From 3fc7fafe8a59648c6c92b32fb932b5101529957f Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Wed, 2 Sep 2026 11:19:58 -0400 Subject: [PATCH 01/10] docs(729): prepare feature folder and atomic plan for test-determinism-and-hygiene-debt Preparation-mode run for issue #729: promotion (issue pre-existing), research, spec.md (21 ACs), and an atomic plan cleared through 6 rounds of atomic-executor preflight (PREFLIGHT: ALL CLEAR). Findings 1-3 are scoped in (TimeProvider seam on NonBlockingDelay.WaitAsync, live-Form guards for UtilitiesCS.Test/SVGControl.Test, DoNotParallelize hazard fixes for the Console.Out race in UtilitiesCS.Test). Finding 4 (QuickFiler.Test pump-timeout) is confirmed non-fixable test-side and is scoped out, promoted as follow-up issue #743. Atomic execution, PR authoring, and CI monitoring are out of scope for this run and are performed later by parallel-orchestrator.

See "Actual Behavior." + +## Expected Behavior + +Per this repo's own determinism-infrastructure policy: tests use an injected `TimeProvider`/`Clock` seam rather than reading wall-clock time directly; no live UI construction in a unit test; parallelizable tests either tolerate parallel execution or are explicitly excluded with a documented reason; load-sensitive timeouts don't cause spurious CI failures under contention. + +## Actual Behavior + +**1. `NonBlockingDelayTests.cs` awaits real wall-clock time.** Confirmed at `TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs:38-39`: `var interval = TimeSpan.FromMilliseconds(30); var stopwatch = Stopwatch.StartNew();` then awaits `NonBlockingDelay.WaitAsync(interval)` against that real stopwatch — no fake-timer/`TimeProvider` seam is used. *(Source: #694.)* + +**2. `UtilitiesCS.Test/ResourceTests.cs` constructs a live WinForms form in a unit test.** Confirmed at line 20: `Form1 frm = new Form1();` inside `TestMethod1`. No structural guard against this exists for `UtilitiesCS.Test` — only `QuickFiler.Test` has an equivalent "no live Form in test assembly" structural test. *(Source: #586.)* + +**3. Two duplicate `DASLFilterParser*Tests.cs` classes lack `[DoNotParallelize]`**, while the test assembly runs `[assembly: Parallelize(Workers=0, Scope=ClassLevel)]` and no console-lock/serialization mechanism exists to make concurrent execution of these two classes safe. *(Source: #520.)* + +**4. Pump-hosted `QfcItemController` tests expire at the 60s `PumpTimeoutMs` under CPU contention.** Load-sensitive flakiness rather than a straightforward logic defect — no simple code fix, but worth tracking as one line item in this consolidated test-infra debt issue rather than its own standalone tracker, since the underlying cause (no environment-aware timeout scaling, or no mocked pump) is the same class of missing-determinism-seam problem as findings 1-3. *(Source: #711.)* + +## Logs / Screenshots + +- [ ] Attached minimal logs or screenshot +- Snippet: n/a — see file/line citations above, each confirmed directly against `origin/main` on 2026-09-02. + +## Impact / Severity + +- [ ] Blocker +- [ ] High +- [x] Medium +- [ ] Low + +Medium: none of these cause incorrect production behavior — they're test-suite reliability/determinism debt that risks intermittent CI failures and slower feedback loops, consistent with this repo's own stated rationale for the determinism-infrastructure policy these findings violate. + +## Suspected Cause / Notes + +Each finding traces to a specific issue, cited inline above.

No absolute host path, account name, or machine name is written into this plan or into any artifact it produces; see P7-T8. + +**Fail-closed evidence rule:** Every command-bearing task writes its own evidence artifact carrying `Timestamp:`, `Command:`, `EXIT_CODE:`, and `Output Summary:`. A task whose artifact is missing or whose fields are incomplete stays UNCHECKED. `EXIT_CODE: SKIPPED` is never a passing outcome unless the task text itself authorizes a skip branch. + +**Evidence location invariant:** All evidence artifacts live under exactly one of these four canonical directories: `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/baseline/`, `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/regression-testing/`, `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/`, and `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/other/`. No artifact is written to any non-canonical location such as an `artifacts/` evidence sub-path. Two transient raw tool outputs are not evidence artifacts and are deliberately kept out of those directories: the TRX files that P6-T5's two scoped node-outcome confirmation runs write to `coverage\trx\p6t5\utilitiescs-noliveform.trx` and `coverage\trx\p6t5\svgcontrol-noliveform.trx`, both untracked under `.gitignore` line 144 `coverage/*`. One derived result line per TRX is transcribed into the canonical P6-T5 artifact, which is what the acceptance reads. + +**Evidence filename timestamp:** Every evidence filename in this plan carries the plan-assigned fixed stamp `2026-09-02T10-30` so that each path is concrete and harvestable. The `Timestamp:` field *inside* each artifact records the actual ISO-8601 execution time, which may differ from the filename stamp. + +--- + +## Scope Recap (orchestrator decisions already made — do not re-litigate) + +**Finding 1 — `TimeProvider` seam.** `TaskMaster/AppGlobals/NonBlockingDelay.cs` is the only production (non-test) file this plan writes. `WaitAsync` is split into an explicit overload pair. An optional `TimeProvider? = null` parameter is **rejected**: it removes the only method-group-conversion candidate at `TaskMaster/AppGlobals/StoreRehookCoordinator.cs` line 102 and yields CS0123 (research §1.2, re-derived below). + +**Finding 2 — live `Form` types, expanded beyond the issue's literal citation.** Issue #729 names only `UtilitiesCS.Test/ResourceTests.cs:20`. That file is an orphan never compiled into `UtilitiesCS.Test`, so acting on the literal citation alone would leave the actual defect untouched. The orchestrator's decision is to **include `SVGControl.Test`**, which is the only site in the repository where a `Form`-derived type is genuinely compiled into a unit-test assembly and therefore the only site where fail-before evidence exists. This expansion is deliberate and is recorded in `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` lines 74–79. + +**Finding 3 — parallel-execution hazard, corrected.** The hazard is not a two-class conflict; it is process-global `Console.Out` mutation under the class-level parallel scope declared at `UtilitiesCS.Test/Properties/AssemblyInfo.cs` lines 18–21. Two compiled classes are unprotected. The new hazard comments cite `AssemblyInfo.cs`, not `TaskMaster.runsettings`: CI passes no `/Settings:` argument, so the existing precedent comments' `TaskMaster.runsettings` citation is stale and must not be repeated. + +**Finding 4 — out of scope.** No file under `QuickFiler/` is added, modified, or deleted by this plan. Finding 4 (pump-hosted `QfcItemController` / `PumpTimeoutMs` load sensitivity) was scoped out and promoted as follow-up issue **#743** (`docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md`). No action is required from this plan beyond recording the citation. The prior standalone tracker #711 was already closed as superseded by #729, so #743 exists specifically so that closing #729 does not drop the finding a second time. + +**Known harvester limitation (surfaced, not worked around).** The repository-relative path `UtilitiesCS.Test/OutlookObjects/Filter DASL/DASLFilterParserTests.cs` contains a space in the directory segment `Filter DASL`. It is written throughout this plan as a single backticked token, but it will **not** survive a whitespace-splitting blast-radius/contention extractor as one token. Renaming the directory is out of scope for this minimal bugfix. Downstream schedulers must treat this one path specially. + +--- + +## Decisions Record (binding on the executor) + +- **D1 — No optional parameter.** Neither `WaitAsync` overload declares an optional parameter. The 1-arg overload must remain the unique 1-parameter candidate so the method-group conversion at `TaskMaster/AppGlobals/StoreRehookCoordinator.cs` line 102 keeps binding to `Func`. +- **D2 — No null guard on `timeProvider`.** The 2-arg overload does **not** validate `timeProvider` for null. `NonBlockingDelay` is `internal static`; its only in-repo caller of the 2-arg overload is the 1-arg overload, which always supplies `TimeProvider.System`. A guard would add a branch outcome that no in-scope test can reach without a fourth test method that the spec's Test Strategy does not authorize, and an unreached branch outcome lowers branch coverage on a changed production file. This is a deliberate minimal-change decision. +- **D3 — No production project-file edit for `TimeProvider`.** Re-derived against the current tree: `TaskMaster/TaskMaster.csproj` already carries `/` outside any plan task, and P0-T15 records that some such paths are already dirty before Phase 1 begins. The `git diff $base HEAD` half of P7-T4 stays an unconditional empty-output assertion because no plan task commits any such path. P7-T2, P7-T4, and P8-T22 therefore evaluate cleanliness against the P0-T15 recorded set plus the `.claude/agent-memory/` allowance rather than against the empty set. +- **D11 — `$base` is re-derived per task.** The shell resets between tasks, so every task whose command text contains `$base` begins its payload with `$base = (git merge-base origin/main HEAD).Trim()` and then asserts that `$base` equals the `BaseRef:` value recorded by P0-T14. A task that finds a different value stops and reports rather than proceeding on a drifted base. +- **D12 — Test-count assertions are numeric, not whitespace-matched.** `vstest.console.exe` summary formatting varies between versions, so no acceptance in this plan matches the console line's internal spacing. Each test task records the passed count and the failed count as integers in its evidence artifact and its acceptance compares those integers. +- **D13 — Cobertura artifacts carry a declared processing state.** `scripts/vscode/Invoke-MSTestWithCoverage.ps1` calls `ConvertTo-KoverageCoberturaXml` at line 340, asserts the 80% line threshold at line 341, and writes the post-processed XML at line 343. Any throw before line 343 — from the collection call at line 326 or from the threshold assertion at line 341 — leaves the raw dotnet-coverage output on disk. The processed and raw forms are not on the same denominator, because the conversion removes non-allowlisted packages and then rewrites the root `line-rate`, `branch-rate`, `lines-covered`, `lines-valid`, `branches-covered`, and `branches-valid` attributes (`Invoke-MSTestWithCoverage.Helpers.ps1` lines 417-447). Both full-suite tasks therefore record `CoberturaProcessingState:` and P6-T6 refuses to compare across a mismatch without converting the raw side first. +- **D14 — One authorized re-run for #743-tracked `QuickFiler.Test` failures, and nothing wider.** `Invoke-DotnetCoverageCollection` throws on any non-zero coverage exit code (`Invoke-MSTestWithCoverage.ps1` lines 235-237), so a single load-sensitive `QuickFiler.Test` pump timeout aborts the whole gate. `spec.md` line 87 records that failure mode as out of scope and carried by issue #743, and this plan modifies no `QuickFiler/` file. The full-suite tasks therefore authorize exactly one mechanical re-run when every failing node is in `QuickFiler.Test`, require the failing node identifiers to be enumerated, and treat a failure in any other assembly as a genuine gate failure. +- **D15 — The Phase 6 formatter pass is staged by P6-T9.** The scope-locked `csharpier format` pass in P6-T1 runs after all five phase commits, so any rewrite it applies to the seven plan-owned formattable source paths is left unstaged by every earlier task. P6-T9 therefore stages those seven paths in addition to the Phase 6 evidence, and P8-T22 amends its own commit to absorb its own check-off line. + +--- + +## Complete file-write inventory + +Production source (exactly one file): + +- `TaskMaster/AppGlobals/NonBlockingDelay.cs` — modified + +Test sources modified: + +- `TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs` +- `UtilitiesCS.Test/OutlookObjects/Filter DASL/DASLFilterParserTests.cs` +- `UtilitiesCS.Test/ReusableTypeClasses/StackGeek_Tests.cs` + +Test sources created: + +- `UtilitiesCS.Test/NoLiveFormInTestAssemblyTests.cs` +- `SVGControl.Test/NoLiveFormInTestAssemblyTests.cs` + +Test project files and package manifests modified: + +- `TaskMaster.Test/TaskMaster.Test.csproj` +- `TaskMaster.Test/packages.config` +- `UtilitiesCS.Test/UtilitiesCS.Test.csproj` +- `SVGControl.Test/SVGControl.Test.csproj` + +Files deleted (17): + +- `UtilitiesCS.Test/ResourceTests.cs` +- `UtilitiesCS.Test/Form1.cs` +- `UtilitiesCS.Test/Form1.Designer.cs` +- `UtilitiesCS.Test/Form1.resx` +- `UtilitiesCS.Test/Form2.cs` +- `UtilitiesCS.Test/Form2.Designer.cs` +- `UtilitiesCS.Test/Form2.resx` +- `UtilitiesCS.Test/Form3.cs` +- `UtilitiesCS.Test/Form3.Designer.cs` +- `UtilitiesCS.Test/Form3.resx` +- `UtilitiesCS.Test/OutlookObjects/DASLFilterParser_Tests.cs` +- `SVGControl.Test/Form1.cs` +- `SVGControl.Test/Form1.Designer.cs` +- `SVGControl.Test/Form1.resx` +- `SVGControl.Test/Form2.cs` +- `SVGControl.Test/Form2.Designer.cs` +- `SVGControl.Test/Form2.resx` + +Feature documentation and evidence written: + +- `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/plan.2026-09-02T08-59.md` +- `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` (AC checkbox state, plus the one Block L insertion under the Finding 4 out-of-scope bullet required by AC16; no other spec content changes) +- `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/issue.md` — authored before this plan and untracked until P8-T22's directory-level `git add` commits it; this plan does not edit its content +- `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/research/research-729.2026-09-02T09-30.md` — authored before this plan and untracked until P8-T22's directory-level `git add` commits it; this plan does not edit its content except for any host-identifier substitution P7-T8 applies +- all artifacts named in Phases 0–8 under `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/` + +Follow-up promotion record committed by this plan: + +- `docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md` — the promotion record for follow-up issue #743, created by this run's MCP promotion and cited by `spec.md` line 87 and by AC16.

If a #743-tracked failure persists after the second run, record it in the artifact and in the delivery-record task as a known out-of-scope flake. A failure in any other assembly is not covered by this branch. Record the field `CoberturaProcessingState:` with the value `processed` when the script exited 0, and the value `raw` when the script exited non-zero under either authorized branch above; the value is `raw` in those cases because `scripts/vscode/Invoke-MSTestWithCoverage.ps1` writes the post-processed XML at line 343 only after both the collection call at line 326 and the threshold assertion at line 341 have returned, so a throw at either point leaves the dotnet-coverage output on disk unrewritten. The runner writes a transient derived coverage-settings file adjacent to the Cobertura output and deletes it in a finally block. Confirm no stranded derived settings file remains before checking this task off: `Test-Path 'docs\features\active\2026-09-02-test-determinism-and-hygiene-debt-729\evidence\baseline\coverage-baseline.cobertura.xml.effective-coverage.config'` returns `False`, and `Get-ChildItem -Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/baseline' -Filter '*.effective-coverage.config'` returns zero items; if either shows the file present, delete it and repeat the confirmation. Acceptance: the artifact records a numeric `line-rate` value, a numeric `branch-rate` value, a `CoberturaProcessingState:` value of `processed` or `raw`, and the two stranded-settings observations above; and it records, per D9, the integer discovered-assembly count matching the `Discovered N test assemblies.` line, the boolean result that zero discovered paths contain a `\worktrees\` segment below the resolved search root, and the repository-relative form of each discovered assembly path with no absolute path written. +- [ ] [P0-T12] From `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/baseline/coverage-baseline.cobertura.xml`, aggregate across every `` element whose `filename` attribute ends with `NonBlockingDelay.cs` the count of `` children with a `hits` attribute greater than zero and the total count of `` children, and record both integers in `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/baseline/nonblockingdelay-coverage-baseline.2026-09-02T10-30.md` as `BaselineCoveredLines:` and `BaselineTotalLines:`. Aggregate by filename rather than by class so any compiler-generated partitioning is summed.

These paths are not introduced by this plan and every later whole-worktree or `.claude`-scoped cleanliness assertion is evaluated against this recorded set rather than against the empty set.

The console line `Formatted N files` is a processed-file count and must NOT be used as the rewritten-file count. A repo-wide `dotnet tool run csharpier format .` is prohibited by D4.

Authorized mechanical branch: if the reported set contains `TaskMaster.Test/packages.config` (which CSharpier processes by filename and which a per-file invocation may skip), run `dotnet tool run csharpier format TaskMaster.Test` in directory form, re-run this check, and record both runs in the artifact. That directory-form invocation is broader than the D4 scope lock, so immediately after it run `git status --porcelain -- TaskMaster.Test` and paste the result into the artifact; every path it reports must already be one of the seven plan-owned formattable paths, and any other path it reports must be reverted to its committed state by running `git checkout HEAD --` applied to that path, with the restoration recorded, before this task is checked off. Acceptance: either `EXIT_CODE: 0`, or the final reported unformatted set is a subset of the `Baseline unformatted set:` recorded by P0-T8 after removing the seventeen paths deleted by Phases 3-5, and contains none of the seven plan-owned formattable paths and none of `UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs`; the artifact states which of the two outcomes held, lists the reported set verbatim, and lists the subset derivation it performed. +- [ ] [P6-T3] Run `& $msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:EnableNETAnalyzers=true /p:EnforceCodeStyleInBuild=true` using the Block K prelude and record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/msbuild-analyzers.2026-09-02T10-30.md`.

Do not add `/p:Nullable=enable`; do not substitute `/t:Build`. Acceptance: `EXIT_CODE: 0` and the artifact's `Output Summary:` states the log contains zero occurrences of `CS8632`. +- [ ] [P6-T5] Run `pwsh -NoProfile -File .\scripts\vscode\Invoke-MSTestWithCoverage.ps1 -SearchRoot . -Configuration Debug -CoverageOutput 'docs\features\active\2026-09-02-test-determinism-and-hygiene-debt-729\evidence\qa-gates\coverage-final.cobertura.xml'` and record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/mstest-coverage.2026-09-02T10-30.md`, pasting into `Output Summary:` the `Discovered N test assemblies.` line, the vstest total/passed/failed counts, and the `line-rate` and `branch-rate` attribute values read from the `` root element of `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/coverage-final.cobertura.xml`. Authorized non-zero branch: if the script exits non-zero and its error text contains the literal `is below the required 80% threshold`, record that observed exit code together with the line `ExpectedExitCode: 1` and the literal note `Threshold assertion fired; raw Cobertura was written before the assertion and the numeric rates below were read from it.` Authorized mechanical re-run branch: if the run reports failures and every failing test node is in `QuickFiler.Test` and is one of the pump-hosted classes tracked by issue #743, re-run this exact command once, record both runs and the full list of failing test node identifiers in the artifact, and treat the second run's counts as authoritative. If a #743-tracked failure persists after the second run, record it in the artifact and in the delivery-record task as a known out-of-scope flake. A failure in any other assembly is not covered by this branch. Record the field `CoberturaProcessingState:` with the value `processed` when the script exited 0, and the value `raw` when the script exited non-zero under either authorized branch above; the value is `raw` in those cases because `scripts/vscode/Invoke-MSTestWithCoverage.ps1` writes the post-processed XML at line 343 only after both the collection call at line 326 and the threshold assertion at line 341 have returned, so a throw at either point leaves the dotnet-coverage output on disk unrewritten. The runner writes a transient derived coverage-settings file adjacent to the Cobertura output and deletes it in a finally block. Confirm no stranded derived settings file remains before checking this task off: `Test-Path 'docs\features\active\2026-09-02-test-determinism-and-hygiene-debt-729\evidence\qa-gates\coverage-final.cobertura.xml.effective-coverage.config'` returns `False`, and `Get-ChildItem -Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates' -Filter '*.effective-coverage.config'` returns zero items; if either shows the file present, delete it and repeat the confirmation. Then, because no logger is configured for the runner's inner vstest invocation (`scripts/vscode/Invoke-MSTestWithCoverage.ps1` line 76 passes only `/Settings:`, `/InIsolation`, and `/TestCaseFilter:`) and the default console logger does not enumerate passing test nodes, obtain the two per-node outcomes from two immediately following scoped confirmation runs using the Block K prelude: `& $vstest UtilitiesCS.Test\bin\Debug\UtilitiesCS.Test.dll /Settings:scripts\vscode\TaskMaster.cli.runsettings /InIsolation /TestCaseFilter:"FullyQualifiedName~NoLiveFormInTestAssemblyTests" /Logger:"trx;LogFileName=utilitiescs-noliveform.trx" /ResultsDirectory:coverage\trx\p6t5` and `& $vstest SVGControl.Test\bin\Debug\SVGControl.Test.dll /Settings:scripts\vscode\TaskMaster.cli.runsettings /InIsolation /TestCaseFilter:"FullyQualifiedName~NoLiveFormInTestAssemblyTests" /Logger:"trx;LogFileName=svgcontrol-noliveform.trx" /ResultsDirectory:coverage\trx\p6t5`. Each TRX contains exactly one `` element; read its `outcome` attribute and pair it with the fully-qualified identifier of the assembly that produced that TRX. Transcribe into `Output Summary:` two lines of the form ` outcome="Passed"`, one per run, plus each run's exit code. Two single-assembly runs are used rather than one combined run because both assemblies declare a class named `NoLiveFormInTestAssemblyTests` with a method named `ExecutingAssembly_ContainsNoFormDerivedType`, and a TRX `` element carries only the bare method name, so a combined TRX cannot distinguish the two nodes without a `` join. Transcribe only the derived fully-qualified test-node identifier and its `outcome` value. Do not paste a raw `` element, which carries a `computerName` host identifier. `coverage/` is gitignored at `.gitignore` line 144, so both TRX files leave the tracked tree clean. This task runs three commands; the artifact's single `Command:` and `EXIT_CODE:` fields carry the `Invoke-MSTestWithCoverage.ps1` run, because that is the run the coverage gate and any `ExpectedExitCode:` apply to, and the two scoped confirmation commands with their own exit codes are recorded inside `Output Summary:`. Acceptance: the artifact records `FailedCount: 0` — or, under the #743 branch above, a `FailedCount:` whose every failing test node identifier is listed in the artifact and is in `QuickFiler.Test` — plus a `PassedCount:` integer greater than 0, a numeric `line-rate`, a numeric `branch-rate`, a `CoberturaProcessingState:` value of `processed` or `raw`, the two stranded-settings observations above, and both literal tokens `UtilitiesCS.Test.NoLiveFormInTestAssemblyTests.ExecutingAssembly_ContainsNoFormDerivedType` and `SVGControl.Test.NoLiveFormInTestAssemblyTests.ExecutingAssembly_ContainsNoFormDerivedType` each recorded with `outcome="Passed"`; and the artifact records, per D9, the integer discovered-assembly count matching the `Discovered N test assemblies.` line, the boolean result that zero discovered paths contain a `\worktrees\` segment below the resolved search root, and the repository-relative form of each discovered assembly path with no absolute path written. +- [ ] [P6-T6] Compare coverage against the Phase 0 baseline and record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/coverage-delta.2026-09-02T10-30.md` with the fields `BaselineLineRate:`, `PostChangeLineRate:`, `BaselineBranchRate:`, `PostChangeBranchRate:`, `BaselineCoveredLines:`, `PostChangeCoveredLines:`, `BaselineTotalLines:`, `PostChangeTotalLines:`, where the four line-count fields aggregate every `` element whose `filename` attribute ends with `NonBlockingDelay.cs`. Before reading any value, compare the `CoberturaProcessingState:` recorded by P0-T11 against the one recorded by P6-T5: both artifacts must declare the same `CoberturaProcessingState:`; if they differ, dot-source `scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1`, call `ConvertTo-KoverageCoberturaXml` with `-RepoRoot (Resolve-Path .).Path` and with `-XmlContent` set to the raw side's content read via `Get-Content -Raw -Encoding UTF8` from `docs\features\active\2026-09-02-test-determinism-and-hygiene-debt-729\evidence\baseline\coverage-baseline.cobertura.xml` when the baseline is the raw side, or from `docs\features\active\2026-09-02-test-determinism-and-hygiene-debt-729\evidence\qa-gates\coverage-final.cobertura.xml` when the post-change run is the raw side, and read the four rate fields and both `NonBlockingDelay.cs` line counts for that side from the converted string rather than from the file on disk, recording in this artifact that this conversion was performed and which side it was applied to. Comparing a raw Cobertura against a processed one is prohibited because `ConvertTo-KoverageCoberturaXml` removes non-allowlisted packages and then rewrites the root `line-rate`, `branch-rate`, `lines-covered`, `lines-valid`, `branches-covered`, and `branches-valid` attributes (`scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1` lines 417-447), so the two forms are not on the same denominator. Acceptance: the artifact records both `CoberturaProcessingState:` values and states whether a conversion was performed; `PostChangeTotalLines` is greater than 0; `PostChangeLineRate` is greater than or equal to `BaselineLineRate`, `PostChangeBranchRate` is greater than or equal to `BaselineBranchRate`, and `PostChangeCoveredLines` divided by `PostChangeTotalLines` is greater than or equal to `BaselineCoveredLines` divided by `BaselineTotalLines`; all eight values and the two comparisons are written into the artifact. `BaselineTotalLines` is already required to be greater than 0 by P0-T12, so both ratios have a non-zero denominator. +- [ ] [P6-T7] Audit file length for the six plan-owned `.cs` files after formatting and record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/file-size-audit.2026-09-02T10-30.md` with one line count per file for `TaskMaster/AppGlobals/NonBlockingDelay.cs`, `TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs`, `UtilitiesCS.Test/NoLiveFormInTestAssemblyTests.cs`, `SVGControl.Test/NoLiveFormInTestAssemblyTests.cs`, `UtilitiesCS.Test/ReusableTypeClasses/StackGeek_Tests.cs`, and `UtilitiesCS.Test/OutlookObjects/Filter DASL/DASLFilterParserTests.cs`. Acceptance: the artifact records six counts and every recorded count is less than or equal to 500. +- [ ] [P6-T8] Record the single-pass toolchain result in `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/toolchain-single-pass.2026-09-02T10-30.md`, listing the five commands from P6-T1 through P6-T5 in order with their exit codes. If P6-T1 reported a `RewrittenFileCount:` greater than 0, or if any of P6-T2 through P6-T5 did not meet its acceptance, re-execute P6-T1 through P6-T5 in order and record the final pass in this same artifact. A P6-T5 artifact recording `ExpectedExitCode: 1` with the literal threshold message and `FailedCount: 0` satisfies this task. A P6-T2 artifact whose final reported unformatted set is a subset of the `Baseline unformatted set:` recorded by P0-T8 after removing the seventeen paths deleted by Phases 3-5, and contains none of the seven plan-owned formattable paths and none of `UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs`, also satisfies this task. Acceptance: the artifact records a final pass in which `RewrittenFileCount:` is 0 and P6-T2 through P6-T5 each met their acceptance, counting the two allowances stated above as met. +- [ ] [P6-T9] Stage and commit all Phase 6 evidence together with any rewrite the P6-T1 scope-locked formatter pass applied to the seven plan-owned formattable source paths, which are committed by Phases 1 through 5 and are therefore not staged by any earlier task. Run `git add docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates 'TaskMaster/AppGlobals/NonBlockingDelay.cs' 'TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs' 'TaskMaster.Test/packages.config' 'UtilitiesCS.Test/NoLiveFormInTestAssemblyTests.cs' 'UtilitiesCS.Test/OutlookObjects/Filter DASL/DASLFilterParserTests.cs' 'UtilitiesCS.Test/ReusableTypeClasses/StackGeek_Tests.cs' 'SVGControl.Test/NoLiveFormInTestAssemblyTests.cs'` and then commit with a subject beginning `chore(729): `. Acceptance: `git status --porcelain` returns empty output for `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates` and for each of the seven plan-owned formattable paths. + +### Phase 7 — Scope-boundary verification and delivery record + +- [ ] [P7-T1] Verify the Finding 3 production file was not touched. Run `git diff --name-only $base HEAD -- 'UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs'` and `git status --porcelain -- 'UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs'`, and record both outputs in `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/scope-boundary-ac17.2026-09-02T10-30.md`. Acceptance: both commands return empty output, and `Select-String -SimpleMatch 'TextWriter' -Path 'UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs'` returns zero matches. +- [ ] [P7-T2] Verify that `TaskMaster/AppGlobals/NonBlockingDelay.cs` is the only non-test production source file changed. Run `git diff --name-status $base HEAD` and `git status --porcelain`, and record the union of both outputs in `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/scope-boundary-ac18.2026-09-02T10-30.md`, classifying every path into exactly one of four buckets: production source; test project asset; feature documentation and evidence, which for this purpose includes the follow-up promotion record `docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md` that P8-T22 commits as deliberate output of this work; or agent-memory scratch, pre-existing or newly written by delegated agents during this plan's execution. The fourth bucket exists because `.claude/agent-memory/` is a tracked directory whose contents are written by the persistent-memory system of delegated agents rather than by any task in this plan, and because P0-T15 records that some such paths are already dirty before Phase 1 begins. A path may be placed in the fourth bucket only if it is under `.claude/agent-memory/` or is listed in the P0-T15 `PreExistingPaths:` set; `docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md` is excluded from the fourth bucket and belongs in the third even though P0-T15 lists it. For the same reason, every path under `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729` belongs in the third bucket even though P0-T15 lists the untracked feature folder: the P0-T15 clause admits a path to the fourth bucket, it does not compel one, and the fourth bucket's subject is agent-memory scratch. Acceptance: exactly one path is classified as production source and it is `TaskMaster/AppGlobals/NonBlockingDelay.cs`; every other path is assigned to one of the remaining three buckets and each fourth-bucket path names which of the two allowances covers it. +- [ ] [P7-T3] Verify no `QuickFiler/` path changed. Run `git diff --name-only $base HEAD -- QuickFiler` and `git status --porcelain -- QuickFiler`, and record both outputs in `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/scope-boundary-ac19.2026-09-02T10-30.md`. Acceptance: both commands return empty output. +- [ ] [P7-T4] Verify no push-down-owned path changed. Run `git diff --name-only $base HEAD -- .claude .codex .agents config/blast-radius.json config/orchestration-routing.json` and `git status --porcelain -- .claude .codex .agents config/blast-radius.json config/orchestration-routing.json`, and record both outputs in `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/scope-boundary-ac20.2026-09-02T10-30.md`. Acceptance: `git diff --name-only $base HEAD -- .claude .codex .agents config/blast-radius.json config/orchestration-routing.json` returns empty output, and every path reported by `git status --porcelain -- .claude .codex .agents config/blast-radius.json config/orchestration-routing.json` is either listed in the P0-T15 `PreExistingPaths:` set or is under `.claude/agent-memory/`, which holds per-agent scratch memory rather than repository policy or configuration content; the artifact enumerates each such path and states which of the two allowances covers it. +- [ ] [P7-T5] Write the changed-file inventory `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/other/changed-file-inventory.2026-09-02T10-30.md` from `git diff --name-status $base HEAD` plus `git status --porcelain`, and compare it line by line against the "Complete file-write inventory" section of this plan. Four differences are known in advance and must be named explicitly in `Deltas:` rather than left unexplained: the `spec.md` Block L insertion authored by P7-T7 and the Phase 8 acceptance-criteria checkbox edits, both of which occur after this task and therefore cannot appear in its diff; and `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/issue.md` together with `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/research/research-729.2026-09-02T09-30.md`, which are authored before this plan, are still untracked at this point, and are committed by P8-T22's directory-level `git add` rather than by any earlier phase commit. Acceptance: the artifact records a `Deltas:` section that is either empty or explains every difference, and that names those two pending `spec.md` changes when the diff does not yet show them and those two untracked feature-documentation paths; the inventory contains exactly seventeen `D` entries. +- [ ] [P7-T6] Write the delivery record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/other/delivery-record.2026-09-02T10-30.md` stating (a) that `UtilitiesCS.Test/NoLiveFormInTestAssemblyTests.cs` is green from birth and is regression prevention rather than a fail-before/pass-after regression test, so no reviewer should expect a red run for it; (b) that `SVGControl.Test/NoLiveFormInTestAssemblyTests.cs` is the genuine red-before/green-after regression test, with the two evidence paths from P3-T4 and P3-T8; (c) the five final toolchain commands with their exit codes from Phase 6; (d) that Finding 4 is out of scope and carried by issue #743; and (e) a section headed `Known out-of-scope flakes:` that either states `None observed` or lists every failing `QuickFiler.Test` test node identifier recorded by the P6-T5 #743 re-run branch. Acceptance: the artifact contains the literal tokens `green-from-birth`, `#743`, `Known out-of-scope flakes:`, and both Phase 3 evidence filenames. +- [ ] [P7-T7] Insert Block L into `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` immediately after the Finding 4 out-of-scope bullet's final sentence and before the next top-level bullet, indenting the heading line and each of the four numbered lines by exactly two spaces so they render as a continuation of that bullet. The Finding 4 bullet is the single line beginning `- **Finding 4 — pump-hosted` in the `### Out of scope / non-goals` section. AC16 requires the four verified reasons to be recorded in the spec itself; today that bullet cites `four independent reasons, §4.2` without enumerating them, so this insertion is what makes AC16 true. Change nothing else in `spec.md` in this task. Acceptance: `Select-String -SimpleMatch 'Finding 4 — reasons no test-only fix exists:' -Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md'` returns exactly one match; `Select-String -SimpleMatch 'The production code reads the context off the control, not from an injected seam.' -Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md'` returns exactly one match, and the same holds for each of the other three Block L reason sentences; before the insertion, record `(Get-Content 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md').Count`; after the insertion, the count has increased by exactly 5, which is the number of lines in Block L (its heading line plus its four numbered lines), and `Select-String -SimpleMatch '- **Finding 4 — pump-hosted' -Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md'` still returns exactly one match, and `Select-String -SimpleMatch 'four independent reasons, §4.2' -Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md'` still returns exactly one match. A ref-anchored diff is deliberately not used here: `spec.md` is untracked until P8-T22, so an anchored diff reports nothing about it and could not fail. Record both line counts and all six search results in `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/other/spec-block-l-insertion.2026-09-02T10-30.md`. +- [ ] [P7-T8] Sweep the feature folder for host identifiers before it is committed. Run a case-insensitive search over every file under `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729` for four things. The first three are fixed-string searches: the account name, derived as `Split-Path -Leaf $env:USERPROFILE`; the machine name, read from `$env:COMPUTERNAME`; and the absolute workspace-root prefix, derived at run time as `(Resolve-Path .).Path`. The fourth is a pattern search rather than a fixed-string search and serves as a residual detector only: a single ASCII letter immediately followed by the two-character drive-root sequence, that sequence constructed at run time as `([string][char]58 + [string][char]92)` so that neither this plan nor this task's own artifact contains the literal. The letter-anchored form is required because the bare two-character sequence occurs three times inside the swept file set in non-host-path contexts — twice in this plan file, where it is preceded by a straight quote and by a backtick, and once in the research artifact inside a regular-expression literal, where it is preceded by an asterisk. Rewriting any of the three would corrupt a recorded acceptance command or a research citation, and leaving them would make the acceptance below unreachable. The letter-anchored form matches none of the three and still matches every genuine absolute path. Replace every workspace-root-prefix hit with `` in its entirety — the whole absolute prefix, never only its drive-root characters, because substituting two characters inside an absolute path drives the residual count to zero while leaving the remainder of that path disclosed — and replace every account-name hit with `` and every machine-name hit with ``, using the XML-escaped forms in any `.xml`, `.cobertura.xml`, `.trx`, or `.coveragexml` artifact, because those placeholders contain angle brackets that would otherwise make the document ill-formed, and re-parse every rewritten XML-family file with `[xml](Get-Content -Raw -Encoding UTF8 $path)` to confirm it is still well-formed. After those three substitutions have been applied, replace every remaining letter-anchored absolute path — the whole path token, from its drive letter to the end of the path — with ``, using the XML-escaped form in any XML-family artifact and re-parsing it afterwards on the same terms. This fourth substitution is required because a raw, unprocessed Cobertura artifact carries third-party build-machine source paths that lie outside the workspace root and are therefore untouched by the workspace-root-prefix substitution, while still being matched by the letter-anchored residual detector: the raw dotnet-coverage output for this solution embeds `Mono.Reflection` source paths rooted at a drive-level `sources` directory. Three raw Cobertura artifacts already committed under `docs/features/active/` in this repository exhibit exactly that — `docs/features/active/2026-08-07-efcviewer-missing-lineage-and-segment-navigation-439/evidence/qa-gates/issue-439-final.cobertura.xml`, `docs/features/active/2026-08-25-quickfiler-high-confidence-partial-screen-backfill-608/evidence/qa-gates/r1-csharp-coverage.2026-08-25T12-33.cobertura.xml`, and `docs/features/active/2026-08-25-quickfiler-high-confidence-partial-screen-backfill-608/evidence/baseline/r3-csharp-coverage.2026-08-25T13-32.cobertura.xml` — each carrying 2,114 lines that the letter-anchored detector matches, of which 15 lines per artifact are the drive-level `sources` third-party paths that lie outside any workspace root and that the workspace-root-prefix substitution therefore cannot reach. A processed Cobertura carries no such path, because `scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1` lines 417-424 remove every non-allowlisted `` and rewrite each retained `class/@filename` to a repository-relative path, so this fourth substitution is a no-op there; every other `*.cobertura.xml` committed under `docs/features/active/` returns zero letter-anchored matches, which confirms it empirically. The fourth substitution is load-bearing only when `CoberturaProcessingState:` is `raw`, which P0-T11 and P6-T5 both explicitly authorize. Without it, `ResidualMatchCount: 0` is unreachable on a plan-authorized execution path. The two Cobertura artifacts are the expected rewrite targets, because dotnet-coverage writes absolute `` and `filename` values into them; both have already been read by P6-T6, which runs earlier, so no later task depends on their pre-substitution content. Record only the post-substitution values; do not quote the pre-substitution values in the evidence artifact itself, and do not spell the account name, the machine name, the absolute workspace-root prefix, or the two-character drive-root sequence literally in it. Rewrites land on files that earlier phase commits already committed, so they are staged and committed by P8-T22's directory-level `git add`. Write `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/host-path-sanitisation.2026-09-02T10-30.md` with `ResidualMatchCount:`, `FilesRewritten:`, `ExternalPathsRewritten:`, and `XmlReparseFailures:`, where `ResidualMatchCount:` is the total number of hits the account-name search, the machine-name search, and the letter-anchored drive-root search return after the substitution pass, counted over the same file set including this artifact, and `ExternalPathsRewritten:` is the number of path tokens the fourth substitution replaced with the `` placeholder, which is `0` when no swept file carried an out-of-workspace absolute path. Acceptance: `ResidualMatchCount: 0`, `XmlReparseFailures: 0`, and an integer `ExternalPathsRewritten:` value is present. + +### Phase 8 — Acceptance-criteria check-off + +Each task below verifies exactly one acceptance criterion in `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` and, only when the stated verification passes, changes that one criterion's checkbox from `- [ ]` to `- [x]` in that file. + +- [ ] [P8-T1] Verify and check off AC1 using the P1-T1 acceptance evidence plus a confirmation that neither `WaitAsync` declaration contains a `=` default in its parameter list and that the 1-arg body is `return WaitAsync(delay, TimeProvider.System);`. +- [ ] [P8-T2] Verify and check off AC2 using P1-T1: `Select-String -SimpleMatch 'timeProvider.CreateTimer(' -Path 'TaskMaster/AppGlobals/NonBlockingDelay.cs'` returns exactly one match, `Select-String -SimpleMatch 'Timeout.InfiniteTimeSpan' -Path 'TaskMaster/AppGlobals/NonBlockingDelay.cs'` returns exactly one match, `Select-String -SimpleMatch 'TaskCreationOptions.RunContinuationsAsynchronously' -Path 'TaskMaster/AppGlobals/NonBlockingDelay.cs'` returns exactly one match, and `Select-String -SimpleMatch 'timer?.Dispose();' -Path 'TaskMaster/AppGlobals/NonBlockingDelay.cs'` returns exactly one match. +- [ ] [P8-T3] Verify and check off AC3 using the P1-T2 acceptance and the P6-T4 artifact's zero-`CS8632` statement. +- [ ] [P8-T4] Verify and check off AC4 using the P6-T3 and P6-T4 artifacts plus `git diff --name-only $base HEAD -- TaskMaster/AppGlobals/StoreRehookCoordinator.cs TaskMaster/AppGlobals/AppEvents.cs` and `git status --porcelain -- TaskMaster/AppGlobals/StoreRehookCoordinator.cs TaskMaster/AppGlobals/AppEvents.cs`, both of which must return empty output. +- [ ] [P8-T5] Verify and check off AC5 using the P2-T1 and P2-T2 acceptances and the P2-T4 artifact. +- [ ] [P8-T6] Verify and check off AC6 using the P2-T4 artifact, which must show all three test methods passing, and the P6-T6 artifact's `PostChangeCoveredLines:` and `PostChangeTotalLines:` values for `TaskMaster/AppGlobals/NonBlockingDelay.cs`. +- [ ] [P8-T7] Verify and check off AC7 using the P1-T3, P1-T4, and P1-T5 acceptances. +- [ ] [P8-T8] Verify and check off AC8 using the P4-T2 acceptance. +- [ ] [P8-T9] Verify and check off AC9 using the P4-T3, P4-T4, and P4-T6 acceptances and the P7-T6 delivery record's green-from-birth statement. +- [ ] [P8-T10] Verify and check off AC10 using the P3-T5 and P3-T6 acceptances. +- [ ] [P8-T11] Verify and check off AC11 using the P3-T1, P3-T2, P3-T8 acceptances and the existence of `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/regression-testing/svgcontrol-guard-fail-before.2026-09-02T10-30.md`. +- [ ] [P8-T12] Verify and check off AC12 using the P6-T5 artifact, whose `Output Summary:` must record both test node identifiers `UtilitiesCS.Test.NoLiveFormInTestAssemblyTests.ExecutingAssembly_ContainsNoFormDerivedType` and `SVGControl.Test.NoLiveFormInTestAssemblyTests.ExecutingAssembly_ContainsNoFormDerivedType` with `outcome="Passed"` against each, alongside the run-level `FailedCount:` recorded by P6-T5 for the whole discovered set; record both identifiers in the check-off note. A per-assembly failure breakdown is not available, because `scripts/vscode/Invoke-MSTestWithCoverage.ps1` line 76 issues one aggregate vstest invocation over the whole discovered assembly set and reports no per-assembly counts. +- [ ] [P8-T13] Verify and check off AC13 using the P5-T1, P5-T2, and P5-T3 acceptances. +- [ ] [P8-T14] Verify and check off AC14 using the P5-T4 and P5-T5 acceptances. +- [ ] [P8-T15] Verify and check off AC15 using the P5-T7 acceptance. +- [ ] [P8-T16] Verify and check off AC16 by confirming `Select-String -SimpleMatch '#743' -Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md'` returns at least one match, `Select-String -SimpleMatch '#711' -Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md'` returns at least one match, and `Select-String -SimpleMatch 'docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md' -Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md'` returns at least one match. Additionally confirm the four-reasons clause of AC16: the P0-T2 scope-recap artifact `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/other/scope-recap.2026-09-02T10-30.md` contains one line equal to `Finding 4 — reasons no test-only fix exists:` followed by four numbered reason lines beginning `1. `, `2. `, `3. `, and `4. `, and `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` contains the heading line and each of the four reason sentences, verified with `Select-String -SimpleMatch` so the two-space continuation indent P7-T7 applies in `spec.md` does not affect the match. The `#743`, `#711`, and promoted-path clauses are satisfied by spec content that already exists and are verified rather than authored here; the four-reasons clause is authored by P7-T7 and verified here. +- [ ] [P8-T17] Verify and check off AC17 using the P7-T1 acceptance. +- [ ] [P8-T18] Verify and check off AC18 using the P7-T2 acceptance. +- [ ] [P8-T19] Verify and check off AC19 using the P7-T3 acceptance. +- [ ] [P8-T20] Verify and check off AC20 using the P7-T4 acceptance. AC20 may be checked off under the P7-T4 carve-out, provided every path reported by `git status --porcelain -- .claude .codex .agents config/blast-radius.json config/orchestration-routing.json` is covered by one of the two allowances P7-T4 states — listed in the P0-T15 `PreExistingPaths:` set, or under `.claude/agent-memory/`. The rationale is that AC20's subject is repository policy and configuration content, and `.claude/agent-memory/` holds per-agent scratch memory written by the persistent-memory system of delegated agents outside any task in this plan. Record in the check-off note the enumerated list of reported paths and, for each, which allowance covers it. If any reported path is covered by neither allowance, leave AC20 unchecked and report it as an outstanding acceptance criterion. +- [ ] [P8-T21] Verify and check off AC21 using the P6-T8 single-pass artifact, which must record `EXIT_CODE: 0` for the csharpier check, the analyzer rebuild, and the nullable rebuild, and `FailedCount: 0` for the coverage-enabled test run, all in the same pass. A P6-T5 artifact recording `ExpectedExitCode: 1` with the literal threshold message and `FailedCount: 0` satisfies this task. A P6-T2 artifact whose final reported unformatted set is a subset of the `Baseline unformatted set:` recorded by P0-T8 after removing the seventeen paths deleted by Phases 3-5, and contains none of the seven plan-owned formattable paths and none of `UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs`, also satisfies this task. A P6-T5 artifact recording a non-zero `FailedCount:` whose every failing test node identifier is enumerated in that artifact and is in `QuickFiler.Test` also satisfies this task, provided P7-T6's `Known out-of-scope flakes:` section lists the same identifiers. If the P6-T2 subset allowance is the outcome that held, leave AC21 unchecked, record the residual unformatted set in the check-off note as a pre-existing condition not owned by this change, and report it as an outstanding acceptance criterion; AC21's literal text requires that `csharpier check` report no unformatted files, which the subset allowance does not establish. +- [ ] [P8-T22] Stage and commit every remaining change with `git add docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729 docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md` and a commit subject beginning `docs(729): `. The promoted record is included because it is the follow-up promotion output of this work that `spec.md` line 87 and AC16 cite, not incidental drift. Acceptance: every path reported by `git status --porcelain` is covered by at least one of three allowances — listed in the P0-T15 `PreExistingPaths:` set; under `.claude/agent-memory/`, which holds per-agent scratch memory written by the persistent-memory system of delegated agents outside any task in this plan; or the single modified-plan-file entry for `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/plan.2026-09-02T08-59.md` representing this task's own check-off — and the check-off note enumerates each reported path with an allowance that covers it. The three allowances deliberately overlap rather than partition: a path recorded by P0-T15 that also sits under `.claude/agent-memory/` is covered twice, which satisfies this acceptance. If any reported path is covered by none of the three, stop and report it. After checking this task off, run `git add docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/plan.2026-09-02T08-59.md` and `git commit --amend --no-edit`, then re-run `git status --porcelain` and confirm every remaining reported path is covered by the first two allowances. + +--- + +## Planner Adversarial Self-Review + +SELF-REVIEW: RE-DERIVED THIS PASS + +Revision round 5 — citations re-derived directly against the current working tree in *this* revision pass. This round applies exactly one delta, the R5-B1 fix confined to P7-T8, so the re-derivation covers that task's own citations and the sibling region that shares its subject matter. + +U1. Bare drive-root-sequence hits in the swept file set — a search of every file under `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729` for the bare two-character drive-root sequence returns exactly three hits in the current tree, unchanged from round 4: `plan.2026-09-02T08-59.md` at the P0-T6 acceptance command, `plan.2026-09-02T08-59.md` at the round-2 sibling-re-check bullet naming P0-T6's absence assertions, and `research/research-729.2026-09-02T09-30.md` line 289 inside a regular-expression literal. The character immediately preceding the sequence is, respectively, a straight single quote (the hit sits inside `-SimpleMatch ':` followed by the escape character and a closing quote), a backtick, and an asterisk closing a `\s*` quantifier. None is an ASCII letter, so the letter-anchored residual detector matches none of the three and none needs rewriting. + +U2. Letter-anchored hits in the swept file set — a search of the same file set for an ASCII letter immediately followed by the drive-root sequence returns zero hits in the current tree, re-run after this round's own edits to P7-T8. This round's inserted prose therefore introduces no account name, no machine name, and no letter-anchored drive-root sequence of its own: it names the placeholder token `` and describes the drive-level `sources` directory in prose rather than spelling any absolute path. The delta does not reintroduce the violation class it exists to close. + +U3. Third-party absolute-path class in raw Cobertura output — of every `*.cobertura.xml` committed under `docs/features/active/` in the current tree, exactly three return any letter-anchored absolute path: `2026-08-07-efcviewer-missing-lineage-and-segment-navigation-439/evidence/qa-gates/issue-439-final.cobertura.xml`, `2026-08-25-quickfiler-high-confidence-partial-screen-backfill-608/evidence/qa-gates/r1-csharp-coverage.2026-08-25T12-33.cobertura.xml`, and `2026-08-25-quickfiler-high-confidence-partial-screen-backfill-608/evidence/baseline/r3-csharp-coverage.2026-08-25T13-32.cobertura.xml`. Each returns exactly 2,114 such lines, of which exactly 15 are rooted at a drive-level `sources` directory and name `Mono.Reflection` sources — for example the `` element in the first of the three. Those 15 lie outside any workspace root, so the workspace-root-prefix substitution cannot reach them while the letter-anchored detector still matches them. Every other Cobertura artifact under `docs/features/active/` returns zero letter-anchored matches, confirming that the fourth substitution is a no-op on processed output. + +U4. `scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1` lines 417-424 — lines 417-421 iterate `$packagesNode.ChildNodes` and `RemoveChild` every element whose `name` is not in `$ProjectNames`; lines 423-424 iterate `//class[@filename]` and assign `ConvertTo-KoverageRelativePath -Path $classNode.filename -RepoRoot $RepoRoot`. This is the mechanism behind U3's empirical finding and is the citation the new P7-T8 sentence carries. + +U5. One authoring correction was applied to the supplied round-5 delta text, for the same reason the round-4 pass corrected two clauses of its own supplied delta: the delta attributed the figure "2,114 such paths per artifact" to the `Mono.Reflection` drive-level `sources` paths, but 2,114 is the count of *all* letter-anchored absolute-path lines per raw artifact and 15 is the count of the drive-level `sources` subset. Writing the supplied figure would have placed a false citation in the plan. Both figures are now stated with the quantity each actually measures, and the three artifacts are named so a third party can re-derive both. The correction does not change which paths the fourth substitution rewrites or what the acceptance requires. The supplied phrase "in a sibling worktree of this repository" was likewise narrowed to "in this repository", because the three artifacts were re-derived in this worktree rather than in a sibling one. + +Sibling-region re-checks performed in revision round 5: + +- Around the P7-T8 edit, first sibling: P0-T6's own acceptance command at the task's `Select-String -SimpleMatch` clause still carries the bare drive-root sequence and is byte-for-byte undisturbed by this round's edit, which touched only text inside P7-T8. P0-T6 remains satisfiable for the reason recorded in round 2 — its artifact enumerates analyzer `Include` values resolved against each declaring project's own directory, which are repository-relative by construction. +- Around the P7-T8 edit, second sibling: the round-2 sibling-re-check bullet that also contains the bare sequence is likewise undisturbed. Both plan-file occurrences are non-letter-anchored, so the fourth substitution does not match them and cannot corrupt either a recorded acceptance command or a recorded self-review finding. +- Around the fourth substitution and P6-T6: P6-T6 is the only task that reads the two Cobertura artifacts, and it runs before P7-T8, so rewriting an out-of-workspace path in a raw artifact strands no later read. The rewrite replaces a `class/@filename` value in a package P6-T6 does not aggregate — P6-T6 aggregates only `` elements whose `filename` ends with `NonBlockingDelay.cs` — so even a re-read would be unaffected. +- Around the fourth substitution and rule 3: a workspace-rooted path is replaced by rule 3 with `` before the fourth rule runs, so the result no longer begins with a drive letter and the fourth rule does not double-rewrite it. The two rules do not compete for the same token. +- Around the new `ExternalPathsRewritten:` field: it is a recorded count, not a threshold. Its acceptance requires only that an integer value be present, so a processed-Cobertura run that rewrites nothing records `0` and passes, while a raw-Cobertura run records the non-zero count. Requiring a non-zero value would have been unsatisfiable on the processed path, which is the mirror image of the defect this round closes. +- Around the AC mapping: this round touches no AC-mapped implementation, test, or evidence task. P7-T8 carries no `AC-MAPPING` entry, so all 21 mappings are unchanged from round 4 and no inventory entry gains or loses a mapping. + +Revision round 4 — citations re-derived directly against the working tree in the round-4 revision pass, covering every citation the four round-3 preflight deltas touched and the sibling region of each edit: + +T1. `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/plan.2026-09-02T08-59.md` and `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/research/research-729.2026-09-02T09-30.md` — a search of the whole feature folder for the bare two-character drive-root sequence returns exactly three hits, all non-host-path: the P0-T6 acceptance command in this plan file, the round-2 sibling-re-check bullet in this plan file that names the absence checks, and the `research-729.2026-09-02T09-30.md` "Primary Search Strategy" bullet whose regular-expression literal contains `\s*` after a colon. Line numbers are deliberately not cited for these three, because they shift with every revision of this plan and the B2 wording does not depend on them. + +T2. Preceding-character re-derivation for the three T1 hits — the P0-T6 hit is preceded by a straight single quote (it sits inside `-SimpleMatch ':` followed by the escape character and a closing quote); the round-2 bullet hit is preceded by a backtick; the research hit is preceded by an asterisk closing the `\s*` quantifier. None of the three is preceded by an ASCII letter, so the letter-anchored residual detector introduced by delta B2 matches none of them, while every genuine absolute path in this environment begins with a drive letter and is matched. `ResidualMatchCount: 0` is therefore reachable without rewriting any of the three. + +T3. Feature-folder account-name search — a search of every file under `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729` for the account name returns zero hits in the current tree, so the account-name component of the P7-T8 residual count is already at zero before the substitution pass and the round-3 B4(i) removals are confirmed still in effect. + +T4. `.claude/agent-memory/task-researcher/project_test_determinism_debt_729.md`, `.claude/agent-memory/atomic-planner/project_729_dirty_tree_and_host_leak_plan_seams.md`, and `docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md` — all three confirmed present on disk in this pass. They are the concrete instances behind the S9 reconstruction, the B1 allowance at P8-T22, and the M1 third-bucket assignment at P7-T2. + +T5. Self-defeat re-check of this round's own edit text — the replacement P7-T8 prose, the replacement P8-T22 acceptance, the amended D10 tail, the amended P7-T2 bucket list, and the rewritten S9 entry each contain no absolute workspace-root prefix, no account name, no machine name, and no ASCII letter immediately followed by the drive-root sequence. This round therefore adds no new hit to any of the four P7-T8 searches and does not make the P7-T8 acceptance self-defeating. + +Sibling-region re-checks performed in revision round 4: + +- Around the D10 tail amendment: P8-T20 is not named in D10's amended final sentence, and does not need to be. P8-T20 does not state a cleanliness rule of its own; it defers explicitly to the two allowances P7-T4 states, and P7-T4 is named. The `git diff $base HEAD` clause that the round-3 wording carried in the same sentence is preserved as its own preceding sentence rather than dropped, so no claim is lost. +- Around the P8-T22 acceptance replacement: P8-T22 still stages exactly the two spans it staged before (`docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729` and the promoted record), so P7-T5's changed-file inventory, its `Deltas:` expectations, and its "exactly seventeen `D` entries" acceptance are unaffected. The amend step and the plan-file self-check-off fixpoint are unchanged; only the set of allowances the post-amend status is measured against widened. +- Around the P7-T2 bucket amendment: P7-T5 compares `git status --porcelain` against the "Complete file-write inventory", which already lists the promoted record under "Follow-up promotion record committed by this plan", so the promoted record produces no unexplained delta there. Agent-memory paths are not in that inventory and therefore do appear as differences at P7-T5, but P7-T5's acceptance requires the `Deltas:` section to *explain* every difference rather than to be empty, so an entry naming them as agent-memory scratch written outside any plan task satisfies it. No edit to P7-T5 is required. +- Around the P7-T8 substitution amendment: P0-T6's acceptance still searches its own artifact for the bare sequence with `Select-String -SimpleMatch`, and that check is unchanged and independent of P7-T8. P0-T6's artifact records analyzer `Include` values resolved against each declaring project's own directory, which are repository-relative by construction, so P0-T6 remains satisfiable. P7-T8 does not rewrite either of the two plan-file occurrences, so it cannot corrupt P0-T6's recorded acceptance command. +- Around the P7-T8 residual-count amendment: the workspace-root-prefix search is a substitution target but is deliberately not one of the three residual searches, because any residual absolute path that survived substitution necessarily begins with a drive letter and is therefore already counted by the letter-anchored search. Omitting it from the residual definition removes a double count, not a check. +- Two authoring corrections were applied to the round-3 delta text itself, each because the supplied wording would have reintroduced the violation class it was written to close. First, the B1 acceptance was supplied as "covered by exactly one of three allowances"; the P0-T15 set and the `.claude/agent-memory/` allowance overlap by construction for the two `task-researcher` paths, so "exactly one" is falsified by the very paths the delta exists to admit. It is written as "at least one", with the overlap stated explicitly. Second, the B2 wording described the letter-anchored detector as part of a "fixed-string search"; a single-ASCII-letter anchor is not expressible as a fixed string, so the first three searches are stated as fixed-string searches and the fourth as a pattern search. Neither correction changes which paths or which text the two tasks accept. +- Around the M1 fourth-bucket restriction: the same admission-versus-compulsion ambiguity that M1 closes for the promoted record also existed for the untracked feature folder, which P0-T15 lists and which the fourth-bucket clause therefore admitted. The restriction now states that feature-folder paths belong in the third bucket for the same reason, so the four buckets partition rather than overlap and the "exactly one of four buckets" instruction is decidable. + +Revision round 3 — citations re-derived directly against the working tree in the round-3 revision pass, covering every citation the twelve round-2 preflight deltas touched and the sibling region of each edit. Entries S8 and S9 were additionally re-derived and corrected in revision round 4: + +S1. `SVGControl.Test/SVGControl.Test.csproj` — line 54 is the opening ``; lines 55-57 `` with `Form`; lines 58-60 `` with `Form1.cs`; lines 61-63 ``; lines 64-66 ``; line 67 ``. The four Form `` elements therefore span 55-66, not 54-66. This is delta m2, re-derived against the tree in this pass rather than accepted from the delta text. +S2. `SVGControl.Test/SVGControl.Test.csproj` — sibling region of S1: line 84 closes the `` holding the `` items and line 85 opens the resource ``; lines 86-88 ``, lines 89-91 ``, lines 92-95 ``, line 96 closes that group. The `86-91` citation is correct and unchanged, and Block H's resource removals still leave `Resources.resx` intact. `.gitignore` lines 144-145 `coverage/*` and `!coverage/.gitkeep` re-derived unchanged. +S3. `scripts/vscode/Invoke-MSTestWithCoverage.ps1` — line 76 appends `@($TestAssembly)` followed by `/Settings:`, `/InIsolation`, and `/TestCaseFilter:TestCategory!=LiveOutlook` to a single `dotnet-coverage collect ... -- ` argument list. That is one aggregate vstest invocation over the whole discovered assembly set with no per-assembly reporting and no `/Logger:`, which is the basis for delta M3's replacement of P8-T12's per-assembly `FailedCount:` demand and for P6-T5's separate scoped confirmation runs. +S4. `scripts/vscode/Invoke-MSTestWithCoverage.ps1` — lines 296-302 build `$testAssemblies` from `Get-ChildItem -Path $resolvedSearchRoot -Recurse -Filter '*.Test.dll'` selecting `FullName`, filtered to `\bin\\` and excluding `\obj\` and `\ref\`; line 315 writes `"Discovered $($testAssemblies.Count) test assemblies."`. Discovered paths are therefore absolute, which is why the round-3 D9 records an integer count, a boolean, and repository-relative forms derived by removing the resolved search-root prefix, rather than asserting an absolute prefix. +S5. `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` — line 87 is a single-line bullet beginning `- **Finding 4 — pump-hosted ` containing the substring `four independent reasons, §4.2` exactly once; line 88 is the next top-level bullet, `- **All \`QuickFiler/\` production sources.**`. This confirms the M2 insertion point (between lines 87 and 88) and confirms both M1 survivor tokens exist exactly once before the insertion. +S6. `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` — line 275 AC20 reads "No file under .claude/\*\*, .codex/\*\*, .agents/\*\*, config/blast-radius.json, or config/orchestration-routing.json is added, modified, or deleted." Its literal text is unqualified, so the B1 carve-out is a documented reading of AC20's subject rather than a match to its literal wording; P8-T20 now states that reading explicitly and requires each reported path to be enumerated against one of the two allowances. +S7. `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` — line 276 AC21 requires that `dotnet tool run csharpier check .` "reports no unformatted files". The P6-T2 subset allowance does not establish that, which is delta m1; P8-T21 now leaves AC21 unchecked under that branch. Lines 254-276 still carry AC1 through AC21, one per line, with no duplicates and no gaps, so the 21-entry inventory below is unchanged. +S8. Feature-folder host-identifier sweep — a case-insensitive search of every file under `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729` for the account name and for a genuine absolute workspace-root prefix returned exactly two hits before revision round 3, both in this plan file: the `Workspace root:` header line and the D9 decision. Delta B4(i) removed both. `spec.md`, `issue.md`, and the research artifact contain no such hit; the two Cobertura artifacts do not yet exist and are the expected rewrite targets. Corrected in revision round 4 as T2 below: the *bare* two-character drive-root sequence, as distinct from a genuine absolute path, has three surviving non-host-path occurrences in the swept set, so the round-3 wording of this entry understated the bare-sequence hit count and the round-3 P7-T8 acceptance was unreachable as written. +S9. Worktree state — `git status --porcelain` now reports six paths rather than the four recorded in revision round 2. The reconstructed list is: a modified `.claude/agent-memory/task-researcher/MEMORY.md`; an untracked `.claude/agent-memory/task-researcher/project_test_determinism_debt_729.md`; a modified `.claude/agent-memory/atomic-planner/MEMORY.md`; an untracked `.claude/agent-memory/atomic-planner/project_729_dirty_tree_and_host_leak_plan_seams.md`; the untracked feature folder `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/`; and the untracked promoted record `docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md`. The four agent-memory entries are tracked-directory writes and are the basis for B1; the promoted record is the #743 promotion output and is the basis for B2 and for M1. The two `atomic-planner` entries were written by the planner's own persistent-memory system after the round-2 observation, which is the direct evidence that `.claude/agent-memory/` paths appear between P0-T15 and P8-T22 and therefore the reason P8-T22 carries the same allowance as P7-T4. Uncertainty is recorded explicitly: the four `.claude/agent-memory/` files and both `docs/` paths were each confirmed present on disk in this pass, and the two `atomic-planner` writes were made by this agent, but no `git status --porcelain` invocation was available to this pass, so the modified-versus-untracked classification of each entry and the exhaustiveness of the six-path list are a reconstruction rather than a direct observation. P0-T15 is the task that records the authoritative set at execution time, and every downstream allowance is evaluated against that recorded set rather than against this reconstruction. + +Sibling-region re-checks performed in revision round 3: + +- Around delta B5's split: both TRX files now live in the same `coverage\trx\p6t5` directory under distinct `LogFileName` values, so neither the round-2 collision analysis nor the `.gitignore` line 144 untracked conclusion changes. The B5 rationale is re-derived rather than asserted: Blocks E and F declare the same class name and the same method name in two namespaces, and a TRX `` carries only the bare method name, so one combined TRX genuinely cannot disambiguate the two nodes. +- Around delta B4(iv)'s `computerName` prohibition: P3-T4, P3-T8, P4-T6, P5-T6, and P2-T4 record counts and node names rather than raw TRX elements, and none of them passes `/Logger:trx` at all, so P6-T5 is the only task that could have leaked a `computerName` attribute. No other task text needs the same restriction. +- Around delta B4(v)'s new P7-T8: it runs after P6-T6, which is the only task that reads the two Cobertura artifacts, so rewriting them strands no later read. Its rewrites land on files already committed by earlier phase commits, and P8-T22's directory-level `git add` stages them, so P7-T8 leaves nothing uncommitted. Its own search-token derivation avoids writing the drive-root literal into the plan or the artifact, so the `ResidualMatchCount: 0` acceptance is not self-defeating. +- Around delta M2's indentation split: P0-T2 still requires the scope-recap artifact to carry unindented `1. ` through `4. ` lines, P7-T7 now requires a two-space indent in `spec.md`, and P8-T16 now verifies each side with `Select-String -SimpleMatch` against the reason sentences rather than demanding the two files match line-for-line. The three tasks are consistent under the new wording. +- Around delta M1's replacement: P7-T7 no longer uses a git-diff acceptance for `spec.md`. The remaining anchored-diff acceptances in the plan (P1-T5, P5-T3, P7-T1, P7-T2, P7-T3, P7-T4, P8-T4) all target tracked paths, so none of them inherits the untracked-blindness defect M1 closes. +- Around delta B1's carve-out: D10 was rewritten so it no longer asserts a clean `.claude/**` tree, which would have contradicted P0-T15 and P7-T4. The `git diff $base HEAD` half of P7-T4 stays an unconditional empty-output assertion, because no plan task commits a `.claude/**` path and the agent-memory writes are never staged. +- Around delta B2's `git add` span: `docs/features/potential/promoted/` is outside the P7-T8 sweep scope, which is the active feature folder only. The promoted record is authored by the MCP promotion route and contains no host identifier; the sweep is not widened to cover it, and P8-T22 commits it as-is. + +Round-2 record, retained for audit and not claimed as re-derived in this pass except where an entry above supersedes it: + +R1. `scripts/vscode/Invoke-MSTestWithCoverage.ps1` — line 76 `Get-DotnetCoverageArgumentList` returns the inner vstest arguments as exactly `/Settings:$RunSettingsPath`, `/InIsolation`, `/TestCaseFilter:TestCategory!=LiveOutlook`. No `/Logger:` and no `/ResultsDirectory` is passed, so the runner's own output cannot enumerate passing test nodes. This is why P6-T5 obtains the two AC12 node outcomes from a separate TRX-logged scoped run rather than from the full-suite console text. +R2. `scripts/vscode/Invoke-MSTestWithCoverage.ps1` — lines 232-237 `Invoke-DotnetCoverageCollection` sets `$global:LASTEXITCODE = 0`, invokes dotnet-coverage, and `throw "MSTest with coverage failed with exit code $coverageExitCode"` on any non-zero code. Basis for D14 and for the authorized #743 re-run branch in P0-T11 and P6-T5. +R3. `scripts/vscode/Invoke-MSTestWithCoverage.ps1` — lines 238-242 the `finally` block removes the derived settings file only when `$shouldRemoveDerivedSettings` is true; lines 118-136 `Get-DerivedCoverageSettingsPath` returns `Join-Path $outputDirectory "$outputName.effective-coverage.config"`. The two concrete stranded-file paths asserted by P0-T11 and P6-T5 are therefore `coverage-baseline.cobertura.xml.effective-coverage.config` and `coverage-final.cobertura.xml.effective-coverage.config` in their respective evidence directories. +R4. `scripts/vscode/Invoke-MSTestWithCoverage.ps1` — lines 326-343: `Invoke-DotnetCoverageCollection` at 326, `ConvertTo-KoverageCoberturaXml` at 340, `Assert-CoberturaLineCoverageThreshold` at 341, `Set-Content` of the processed XML at 343. A throw at 326 or 341 leaves the raw dotnet-coverage file on disk. Basis for D13 and for the `CoberturaProcessingState:` field. +R5. `scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1` — lines 417-447 `ConvertTo-KoverageCoberturaXml` removes every `` whose `name` is not in the allowlist, calls `Remove-CoberturaExemptClosureCoverage` and `Merge-CoberturaClassesByFilename`, then `SetAttribute`s all six root aggregates (`line-rate`, `branch-rate`, `lines-covered`, `lines-valid`, `branches-covered`, `branches-valid`). Confirms raw and processed Cobertura are not on the same denominator, which is what P6-T6's new same-state precondition guards. +R6. `scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1` — line 489 `throw "Cobertura line coverage $formattedPercentage% is below the required 80% threshold."`. The literal substring asserted by the authorized non-zero branch in both P0-T11 and P6-T5 is `is below the required 80% threshold`, which is present in that message verbatim. +R7. `.gitignore` — line 144 `coverage/*` and line 145 `!coverage/.gitkeep`. Confirms the P6-T5 TRX destinations, now `coverage\trx\p6t5\utilitiescs-noliveform.trx` and `coverage\trx\p6t5\svgcontrol-noliveform.trx` after the round-3 B5 split, are untracked and cannot dirty the worktree ahead of P6-T9 or P8-T22. Re-derived again in round 3 as S2 below. +R8. `.csharpierignore` — lines 4-8 `**/evidence/**`, `*.cobertura.xml`, `*.coverage`, `*.coveragexml`, `*.trx`; lines 12-14 `*.csproj`, `*.props`, `*.targets`. Markdown is not processed by CSharpier at all, so the P7-T7 `spec.md` insertion cannot be rewritten by the P6-T1 format pass, and the new TRX is doubly exempt. +R9. `scripts/vscode/TaskMaster.cli.runsettings` — present in the tree; it is the `/Settings:` file the P6-T5 scoped confirmation run passes, matching the form already used by P2-T4, P3-T4, P4-T6, and P5-T6. +R10. `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/research/research-729.2026-09-02T09-30.md` — line 238 heading `### 4.2 Why the pump cannot be faked from the test side`; line 240 states the replacement "is nevertheless not *sufficient*, for four independently verified reasons"; the four bolded lead sentences are at lines 242, 248, 250, and 252 and are reproduced verbatim in Block L. +R11. `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` — line 87 is the `### Out of scope / non-goals` bullet beginning `- **Finding 4 — pump-hosted `; it cites "four independent reasons, §4.2" but does **not** enumerate them, and a whole-file search for the four reason sentences returns zero matches. AC16 at line 271 requires the four reasons to be recorded "in this spec". The prior round's P8-T16 claim that AC16 "is satisfied by spec content that already exists" was therefore false for that clause, which is why P7-T7 now authors the enumeration and P8-T16 verifies it. This is a sibling-region finding produced by the DEF-8 re-derivation, not one of the ten supplied deltas. +R12. `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` — line 267 AC12 requires both guard tests "passing in the final full test run"; line 271 AC16 as quoted in R11. The acceptance-criteria block still runs AC1 through AC21 with no duplicates and no gaps, so the 21-entry AC inventory below is unchanged. +R13. `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` — line 235 states the `SVGControl.Test` guard is the genuine red-before/green-after test and line 234 states the `UtilitiesCS.Test` guard is green from birth. Unchanged by this revision; P8-T12's rewording asserts node outcomes and does not disturb that distinction. +R14. Sibling region of the DEF-4 edit — P1-T8, P2-T6, P3-T9, P4-T7, and P5-T8 stage only their own phase paths, and none of them runs after P6-T1. Confirms that without the P6-T9 change no task stages a P6-T1 rewrite, and that adding the seven paths to P6-T9 double-stages nothing. +R15. Sibling region of the DEF-6 edit — P6-T2's authorized branch runs `csharpier format` in *directory* form over `TaskMaster.Test`, which is broader than the D4 scope lock. That branch now carries a `git status --porcelain -- TaskMaster.Test` observation and a revert instruction, because an out-of-scope rewrite there would survive P6-T9's path-scoped staging and only surface as a dirty worktree at P8-T22. This is a sibling-region finding produced by the DEF-4/DEF-6 re-derivation. +R16. Sibling region of the DEF-9 edit — the delta's literal wording ("no file other than the named Cobertura artifact and this task's evidence markdown is present in that evidence directory") is unsatisfiable as written, because `evidence/baseline/` also holds the P0-T1 through P0-T10, P0-T12, P0-T13, and P0-T14 artifacts by construction. The intent — no stranded derived settings file — is preserved as a concrete two-part absence assertion naming the exact `*.effective-coverage.config` path. + +Citations re-derived directly against the working tree in the original authoring pass. No edit in revision round 2 touched any file or region cited below, except `.csharpierignore` (entry 25), `.gitignore` (entry 26), `scripts/vscode/Invoke-MSTestWithCoverage.ps1` (entry 28), `scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1` (entry 29), and `spec.md` (entry 32) — each of which was re-derived again in the round-2 pass as R1 through R12 above and found unchanged.

The `System.Windows.Forms` reference is a standalone framework reference and survives the Block H removals, so Block E compiles. +15. `SVGControl.Test/SVGControl.Test.csproj` — lines 9-10 default `Configuration` to `Debug` and `Platform` to `AnyCPU`; line 29 is the `Debug|AnyCPU` condition with `OutputPath bin\Debug\`. This is the basis for D6. +16. `SVGControl.Test/` directory listing — all six form files present on disk: `Form1.cs`, `Form1.Designer.cs`, `Form1.resx`, `Form2.cs`, `Form2.Designer.cs`, `Form2.resx`. +17. `QuickFiler.Test/NoLiveFormInTestAssemblyTests.cs` — 54 lines, namespace at line 7, `typeof(System.Windows.Forms.Form)` at line 20, `GetLoadableTypes` with the `ReflectionTypeLoadException` fallback at lines 42-52. Blocks E and F are this file with only the namespace line changed. +18. `UtilitiesCS.Test/UtilitiesCS.Test.csproj` — line 76 `` (the Block G insertion anchor); line 270 ``. A search for `ResourceTests.cs`, `Form1`, `Form2`, `Form3`, and `DASLFilterParser_Tests` across that project file returns matches only for line 270's `DASLFilterParserTests.cs`, confirming all eleven deletion targets in `UtilitiesCS.Test/` are unreferenced orphans. +19. `UtilitiesCS.Test/` directory listing — all ten orphan files present on disk; `UtilitiesCS.Test/OutlookObjects/DASLFilterParser_Tests.cs` present on disk. +20. `UtilitiesCS.Test/Properties/AssemblyInfo.cs` — lines 18-21 `[assembly: Parallelize(Workers = 0, Scope = Microsoft.VisualStudio.TestTools.UnitTesting.ExecutionScope.ClassLevel)]`.

Confirms `packages/` and `coverage/` stay untracked, so no restore or coverage run dirties the tree. +27. `scripts/vscode/Invoke-Restore.ps1` — parameters `-SolutionPath` (default `TaskMaster.sln`), `-Configuration`, `-Platform`; vswhere resolution at lines 22-30; restore command at line 36 with `/t:Restore /p:RestorePackagesConfig=true /m`. +28. `scripts/vscode/Invoke-MSTestWithCoverage.ps1` — parameters `-SearchRoot`, `-Configuration`, `-CoverageOutput`, `-NoExecute`; search-root resolution at lines 271-272; discovery filter at lines 296-302 (excludes `\obj\` and `\ref\` only, which is the basis for D9); `dotnet-coverage` presence check at lines 292-293; prints `Discovered N test assemblies.` at line 315; `Assert-CoberturaLineCoverageThreshold` called at line 341 before the post-processed `Set-Content` at line 343. +29. `scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1` — lines 459-491 `Assert-CoberturaLineCoverageThreshold` throws when the root `` `line-rate` times 100 is below 80. This is the basis for the authorized non-zero branch in P0-T11 and for D5. +30. `scripts/vscode/` directory listing — `Install-RepoDotNetSdk.ps1`, `Invoke-Restore.ps1`, `Invoke-MSTest.ps1`, `Invoke-MSTestWithCoverage.ps1`, and `TaskMaster.cli.runsettings`'s sibling scripts all present. +31. `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/issue.md` — line 12 `- Work Mode: full-bug`, which resolves the mode per the contract's precedence rule. +32. `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` — 21 acceptance criteria at lines 256-276, one per line, IDs AC1 through AC21 with no duplicates and no gaps. + +Sibling-region re-checks performed in revision round 2: + +- Around P6-T5's TRX confirmation: the two assemblies it names, `UtilitiesCS.Test\bin\Debug\UtilitiesCS.Test.dll` and `SVGControl.Test\bin\Debug\SVGControl.Test.dll`, are exactly the outputs P4-T5 and P3-T3 assert with `Test-Path`, so both exist by the time Phase 6 runs. Each `/Logger:trx` form carries both `/ResultsDirectory` and an explicit `LogFileName`, and writes into a task-specific subdirectory under distinct filenames, so the two runs cannot collide with each other or with any other TRX. Superseded in round 3 by the B5 split into two single-assembly runs; re-derived as S3 below. +- Around P6-T9's widened staging: the seventh path, `UtilitiesCS.Test/OutlookObjects/Filter DASL/DASLFilterParserTests.cs`, contains a space and is single-quoted in the `git add` span, matching the quoting P5-T8 already uses for the same path. +- Around P7-T7's new `spec.md` edit: `P7-T2` (AC18) classifies every changed path as production source, test project asset, or feature documentation and evidence — `spec.md` falls in the third class, so the AC18 "exactly one production source path" acceptance is unaffected. `P7-T5` asserts exactly seventeen `D` entries; a content edit to `spec.md` adds an `M` entry, not a `D` entry, and `spec.md` is already named in the Complete file-write inventory, whose wording this revision updated to cover the Block L insertion. +- Around P8-T22's amend: the amended commit is local and unpushed at that point in the plan, and `P8-T22` is the last task in the plan, so no later task depends on the pre-amend commit hash. +- Around P0-T6's new absence assertions: the artifact enumerates analyzer `Include` values resolved against each declaring project's own directory, which are repository-relative by construction, so the `:\` and account-name absence checks are satisfiable by the artifact this task is instructed to write rather than being a constraint it cannot meet. + +Sibling-region re-checks performed in the original authoring pass: + +- Around `NonBlockingDelay.cs` lines 42-66: the class remarks at lines 10-30 reference `` and ``. Block A rewrites the remarks so no `cref` points at a type the file no longer constructs, while keeping `` valid against the surviving 1-arg overload. No `.csproj` in the solution sets `DocumentationFile`, so no CS0419 ambiguity arises from the added overload. +- Around `StoreRehookCoordinator.cs` line 102: the sibling XML doc at line 72 carries `` with no parameter list. That cref stays valid and is unaffected by the added overload for the same `DocumentationFile` reason. The plan does not edit that file. +- Around `SVGControl.Test/SVGControl.Test.csproj` lines 55-66: the sibling `` entries for `GetRelativePath_Test.cs`, `RelativePathCoverageTests.cs`, `SvgAssemblyProbeDirectoryTests.cs`, `SvgRendererNullToleranceTests.cs`, `SvgRendererParseContractTests.cs`, `Properties\AssemblyInfo.cs`, and `Resources.Designer.cs` are untouched by Block H, and the sibling `` at lines 92-95 is untouched by Block H's resource removals. +- Around `UtilitiesCS.Test/UtilitiesCS.Test.csproj` line 76: the sibling entries at lines 73-75 and 77 are untouched by the Block G insertion. +- Around the two Finding 3 classes: `UtilitiesCS.Test/HelperClasses/NLogTraceWriter_Test.cs` also captures and restores `Console.Out` but asserts through Moq rather than on captured text, so it has no failing mode of its own and is deliberately left unmarked per spec lines 90 and 293. This plan does not touch it. +- Around the deleted `UtilitiesCS.Test/OutlookObjects/DASLFilterParser_Tests.cs`: its sibling `UtilitiesCS.Test/OutlookObjects/Filter DASL/DASLFilterParserTests.cs` is the compiled copy at csproj line 270 and is retained; deleting the orphan removes no compiled test. + +--- + +## Planner Internal Review Record + +PLANNER-INTERNAL-REVIEW: PASS + +CITATION-TO-TREE: PASS +AC-TRACEABILITY: PASS +SCOPE-BOUNDARY: PASS + +CITATION: TaskMaster/AppGlobals/NonBlockingDelay.cs | line 42 `public static Task WaitAsync(TimeSpan delay)` +CITATION: TaskMaster/AppGlobals/NonBlockingDelay.cs | lines 52-54 nullable annotations pragma pair around `Timer? timer = null;` +CITATION: TaskMaster/AppGlobals/StoreRehookCoordinator.cs | line 102 `_delay = delay ??

Verified by `Glob quality-tiers.*` → only `.claude/rules/quality-tiers.md` matched. The tier-classification gate described in `.claude/rules/quality-tiers.md` therefore has no data file in this repository, and no tier can be cited for `UtilitiesCS`, `TaskMaster`, or `QuickFiler`.

The rewritten tests must therefore be ordered *start task → advance → await*: + +- `WaitAsync_WithNoDispatcher_CompletesAfterInterval`: start the task, assert it is **not** completed, `fake.Advance(interval)`, then `await`. This is a strictly stronger assertion than the current `Stopwatch` check (it proves the task cannot complete early) and removes the `Stopwatch` entirely. +- `WaitAsync_ZeroDelay_CompletesWithoutPump`: start the task, `fake.Advance(TimeSpan.Zero)`, then `await`.

There is no live `Form` in `UtilitiesCS.Test` today, and no `ShowDialog()` can execute from it.

The plan must state this explicitly rather than claim a red-before run. + +There is also a third form, **`Form3`**, not mentioned in the delegation: `UtilitiesCS.Test/Form3.cs:13` (`public partial class Form3 : Form`), plus `Form3.Designer.cs` and `Form3.resx`.

No csproj edit is needed (none are referenced). Deleting the whole set is preferable to gutting `[Ignore]`d method bodies, because gutting leaves the `Form` sources on disk one csproj line away from re-entering the assembly. +2. Add the ported guard to `UtilitiesCS.Test`, documented as green-from-birth regression prevention. +3. **Decide scope for `SVGControl.Test`.** It is the only live violation and is where the fail-before evidence exists. It is not named in issue #729. Recommendation: include it, because excluding it means #729 ships a guard in the assembly that was already clean while leaving the dirty assembly untouched. If the orchestrator prefers strict issue fidelity, promote it as a follow-up issue and say so in the spec. + +--- + +## 3. Finding 3 — parallel-execution hazard in the DASL parser tests + +### 3.1 Corrected premise + +`UtilitiesCS.Test/OutlookObjects/DASLFilterParser_Tests.cs` and `UtilitiesCS.Test/OutlookObjects/Filter DASL/DASLFilterParserTests.cs` are byte-identical apart from namespace and class name (both 118 lines; same six test methods, same bodies). **Only the latter is compiled** — `UtilitiesCS.Test.csproj:270` includes `OutlookObjects\Filter DASL\DASLFilterParserTests.cs`, and `Grep DASLFilterParser_Tests` against the csproj returns no match. + +Therefore there is **no class-versus-class conflict between these two files**, because one of them is not in the assembly. The delegation's framing of the hazard is wrong. + +### 3.2 The actual shared resource + +`DASLFilterParserTests.PrintTree_WritesIndentedTreeToConsole` (L94-116) mutates **process-global `System.Console.Out`**: + +``` +L100 using var writer = new StringWriter(); +L101 var originalOut = Console.Out; +L102 Console.SetOut(writer); +L107 parser.PrintTree(tree, 0); +L111 Console.SetOut(originalOut); +L115 writer.ToString().Should().Contain("AND").And.Contain(" A").And.Contain(" B"); +``` + +The redirect is unavoidable at the test level because the production method writes directly to the console: `UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs:97-104`, `public void PrintTree(TreeNode node, int level) { Console.WriteLine(...); ... }` — there is no `TextWriter` parameter to inject. + +Under `[assembly: Parallelize(Workers = 0, Scope = ExecutionScope.ClassLevel)]` (`UtilitiesCS.Test/Properties/AssemblyInfo.cs:18-21`, live in CI per §0), this class runs concurrently with roughly thirty sibling classes that call `Console.SetOut(...)` in `[TestInitialize]` (e.g. `Threading/AppGlobalsConverterTests.cs:27`, `NewtonsoftHelpers/*.cs`, `EmailIntelligence/Bayesian/*.cs`). Two concrete failure modes: + +1. **Swallowed output.** A sibling's `Console.SetOut(new DebugTextWriter())` executes between L102 and L107, so `PrintTree`'s output lands in the sibling's writer, `writer.ToString()` is empty, and the assertion at L115 fails. +2. **Stale-writer leak.** If a sibling captures `Console.Out` while this test's `StringWriter` is installed, its own restore reinstalls that `StringWriter` *after* the `using` at L100 has disposed it. Every later `Console.Write` in the process then throws `ObjectDisposedException`, turning one interleaving into a cascade of unrelated failures. + +### 3.3 The repo already has the remedy and its precedent + +Two `UtilitiesCS.Test` classes already carry `[DoNotParallelize]` with a comment naming this exact hazard: + +- `UtilitiesCS.Test/HelperClasses/PrettyPrint_Tests.cs:14-20` — "captures and restores `Console.Out`, which is process-wide state. Under the class-level parallel scope ... a sibling test class's `Console.SetOut` overrides this class's redirect mid-test". +- `UtilitiesCS.Test/OutlookObjects/Table/OlTableExtensions_Tests.cs:17-21` — "redirects `Console.Out`, which is process-wide state. Under class-level parallel execution another test class can replace the writer mid-test and make the captured output empty." + +`[DoNotParallelize]` is in `Microsoft.VisualStudio.TestTools.UnitTesting`, already imported by both target files (`DASLFilterParserTests.cs:4`). MSTest partitions the assembly into a parallel set and a non-parallel set and runs the non-parallel set serially, so marking a class removes it from every concurrent window. + +### 3.4 A third unprotected class exists + +`UtilitiesCS.Test/ReusableTypeClasses/StackGeek_Tests.cs` is compiled (`UtilitiesCS.Test.csproj:431`), declares `[TestClass]` at L9 with **no** `[DoNotParallelize]`, and `Main_RunsSampleScenarioWithoutThrowing` (L139-161) performs the identical capture-assert-restore on `Console.Out` (L144, L146, L155, asserting at L159-160). It is exposed to exactly the same two failure modes. + +`UtilitiesCS.Test/HelperClasses/NLogTraceWriter_Test.cs` (csproj:73) is a related but distinct case: it captures `originalOut` in `[TestInitialize]` (L22-23) and restores it in `[TestCleanup]` (L56), but installs a `DebugTextWriter` and asserts through Moq rather than on captured text. It cannot fail from a swallowed redirect, but it *is* a stale-writer-leak source (failure mode 2). It is listed here for completeness; marking it is optional and not recommended as part of this fix, since it would serialize a class with no failing mode of its own. + +### 3.5 Recommended disposition + +- Add `[DoNotParallelize]` plus a one-line hazard comment (matching the `PrettyPrint_Tests` / `OlTableExtensions_Tests` wording) to **`DASLFilterParserTests`** and **`StackGeek_Tests`**. +- Delete the orphan duplicate `UtilitiesCS.Test/OutlookObjects/DASLFilterParser_Tests.cs`. Leaving it invites a future contributor to add it to the csproj, at which point two identically-named test methods in two classes both mutate `Console.Out`. +- Do **not** attempt to seam `DASLFilterParser.PrintTree` to accept a `TextWriter`. That is a `UtilitiesCS` production API change with no defect behind it, outside the bugfix minimal-change rule. + +Fail-before evidence: this hazard is a race, so a deterministic red run is not producible. The plan should record a fail-before exception dossier (`evidence/regression-testing/fail-before-exception..md`) with `WhyFailingRunImpossible` stating that the failure requires a specific interleaving of `Console.SetOut` across two threads, and use the two in-repo precedent comments as the alternative proof that the hazard is real and previously observed. + +--- + +## 4. Finding 4 — `PumpTimeoutMs = 60000` load sensitivity + +### 4.1 What the constant actually is + +`PumpTimeoutMs` is used in **exactly 19 places, all of them the argument of an MSTest `[Timeout(...)]` attribute**, plus 4 declarations. It is **never** used as a wait duration, a poll interval, or a `WaitOne`/`Wait` argument. Verified by `Grep PumpTimeoutMs` over `QuickFiler.Test` (full result set, 23 lines: 4 declarations + 19 `[Timeout(PumpTimeoutMs)]` usages). + +Every wait inside these tests is on a `TaskCompletionSource`-backed `Task` completed by the pump — see `WinFormsPumpHost.CreateCompletion()` (`QuickFiler.Test/TestSupport/WinFormsPumpHost.cs:364-365`) and the `Post`/`RunAsync` members. There is no `Thread.Sleep`, no `Task.Delay`, no `Stopwatch`, and no polling loop. **The test logic is already deterministic in the sense the determinism rule requires** (`.claude/rules/general-unit-test.md:104` bans `Thread.Sleep`, `Task.Delay`, real wall-clock waits, `Date.now()` — none is present). + +The failure mode is narrower than "non-deterministic tests": under CPU contention the *real elapsed cost of the work under test* can exceed the 60 s harness bound and MSTest aborts an otherwise-correct test. + +### 4.2 Why the pump cannot be faked from the test side + +`WinFormsPumpHost` is test-owned (`QuickFiler.Test/TestSupport/WinFormsPumpHost.cs`, compiled at `QuickFiler.Test.csproj:202`), so replacing it is *permissible* under the file-ownership constraint. It is nevertheless not *sufficient*, for four independently verified reasons: + +1. **The production code reads the context off the control, not from an injected seam.** `QuickFiler/Viewers/ItemViewer.cs:23-29`: + ``` + public ItemViewer() { InitializeComponent(); _context = SynchronizationContext.Current; _uiDispatcher = Dispatcher.CurrentDispatcher; InitControlGroups(); } + ``` + with `UiSyncContext => _context` (L59-62), exposed read-only through `IItemViewer.UiSyncContext` (`QuickFiler/Viewers/IItemViewer.cs:37`). The members under test await it directly — `QuickFiler/Controllers/QfcItemController.ViewerSetup.cs:64` (`await _itemViewer.UiSyncContext;`), L320, L331, L336. To substitute a synchronous fake context the *viewer* must be constructed on a thread where that fake is `SynchronizationContext.Current`, which means the ItemViewer must be constructed off the pump. That is a production-behaviour dependency, not a test-harness one. + +2. **The fixture's cost is the real WinForms control tree, not the pump.** `QuickFiler.Test/Controllers/QfcItemController.InitializationTests.Part2.cs:74` constructs a real `QuickFiler.ItemViewer` on the pump, and L84 forces `viewer.Handle`. The in-file comment at L77-83 records the measured fact (2026-08-22) that "**both WebView2 children — and therefore the parent ItemViewer — are already handle-created when construction returns**". Constructing two WebView2 controls plus their WinForms handles is the dominant cost, and it is unaffected by any change to the pump implementation. `QuickFiler.Test/Viewers/WebView2BreadcrumbHostTests.cs:38`, `:88` construct `new WebView2()` for the same reason. A fake `SynchronizationContext` cannot service WinForms handle creation or `Control.BeginInvoke` marshalling; only a real Win32 message loop can. + +3. **`[DoNotParallelize]` would be a no-op.** `QuickFiler.Test/Properties/AssemblyInfo.cs` declares no `Parallelize` attribute and CI passes no `/Settings:` (§0), so `QuickFiler.Test` already runs serially. The contention comes from the runner host and from `/EnableCodeCoverage` instrumentation, neither of which an in-repo attribute can influence. (Two classes already carry `[DoNotParallelize]` — `Helper Classes/ViewerQueueStaticWrapperTests.cs:11`, `Helper Classes/EmailMoveMonitorTests.cs:22` — for static-state reasons, not timing.) + +4. **Removing `[Timeout]` trades a bounded failure for an unbounded hang.** The attribute's documented purpose is stated in-file at `QfcItemController.InitializationTests.cs:33-37`: it "only converts a genuine deadlock in production code into a test failure instead of a CI hang." Deleting it would let a real deadlock consume the workflow's 30-minute budget instead. + +### 4.3 Definitive recommendation — conclusion (b) + +**No test-only change removes the load sensitivity.** The only durable fix is a `QuickFiler/` production seam: give the members under test an injectable UI-marshalling abstraction (an `IUiDispatcher`/`SynchronizationContext` parameter or settable seam on `QfcItemController`, and an interface over the `WebView2` control accepted by `WebView2BreadcrumbHost`'s constructor) so a synchronous fake can replace the message loop entirely. `QuickFiler/` production sources are owned by other parallel work items in this run. + +**Action:** scope Finding 4 **out** of issue #729's spec and promote it as its own follow-up issue via the potential-to-issue lifecycle. The follow-up should carry the four points above verbatim as its evidence, and should note that issue #711 was already closed as "superseded by #729", so closing #729 without either fixing or re-promoting this finding would silently drop it a second time. + +**Permitted but non-remedial hygiene, if the orchestrator wants any test-side change here:** the constant is declared four times — `QfcItemController.InitializationTests.cs:38` (`internal const`, consumed by `.Part3.cs`), `QfcItemController.SeamFactoryTests.cs:327` (`private const`), `QfcItemController.ViewerSetupTests.cs:34` (`private const`), `WebView2BreadcrumbHostTests.cs:25` (`private const`). Hoisting one `internal const int PumpTimeoutMs` into `QuickFiler.Test/TestSupport/` and referencing it from all four gives a single source of truth. This is duplication hygiene only; it does not address the finding and must not be presented as doing so. + +--- + +## 5.

NonBlockingDelay.WaitAsync;` binding to `Func`); C# forbids a method-group conversion when an optional parameter has no corresponding delegate parameter, producing CS0123.

They are orphan files on disk that never enter the assembly, so no live `Form` is reachable from `UtilitiesCS.Test` today.

The real hazard is that the compiled class mutates process-global `Console.Out` while roughly thirty sibling classes do the same under the class-level parallel scope.

This promotion is load-bearing: the prior standalone tracker for this same finding, **#711**, was already closed as "superseded by #729", so #743 exists specifically so that closing #729 does not silently drop the finding a second time. +- **All `QuickFiler/` production sources.** These are owned by a different parallel work item in this run. No file under `QuickFiler/` is modified by #729. +- **No production API seam for `DASLFilterParser.PrintTree`.** Giving `PrintTree` a `TextWriter` parameter would be an unrelated `UtilitiesCS` production API change with no defect behind it, outside the bugfix minimal-change rule (research §3.5). +- **No `[DoNotParallelize]` on UtilitiesCS.Test/HelperClasses/NLogTraceWriter_Test.cs.** It captures and restores `Console.Out` but asserts through Moq rather than on captured text, so it has no failing mode of its own; marking it would serialize a class for no benefit (research §3.4). +- **No `PumpTimeoutMs` constant-hoisting hygiene in QuickFiler.Test.** Research §4.3 lists this as permitted but non-remedial; it is excluded to keep the change minimal and to avoid touching a parallel work item's assembly. +- **No `app.config` change in TaskMaster.Test.** The `Microsoft.Bcl.TimeProvider` binding redirect is already present (TaskMaster.Test/app.config lines 265-271) and no redirect exists or is needed for `Microsoft.Extensions.TimeProvider.Testing` (research §1.5). + +### Explicitly excluded systems, integrations, or datasets + +- No file under .claude/**, .codex/**, .agents/**, config/blast-radius.json, or config/orchestration-routing.json is modified. These are push-down-owned from an upstream repository and any defect in them must be fixed upstream. +- No Outlook/COM interaction, no network, no filesystem temporary files. All changes are compile-time or reflection-over-metadata only. + +## Root Cause Analysis + +Each finding traces to a specific issue, cited inline above. All four share the same root class: a test depends on real time, real UI, or real environmental load instead of an injected, controllable seam — exactly what .claude/rules/general-unit-test.md's "Determinism Infrastructure" section already mandates repo-wide but which these four tests predate or were missed by. The per-finding root causes below are the **corrected** ones established by research on 2026-09-02. + +**Finding 1 — no seam exists, and the obvious seam shape is blocked by a method-group conversion constraint.** `NonBlockingDelay.WaitAsync` builds its one-shot timer with `new System.Threading.Timer(...)` directly (NonBlockingDelay.cs lines 55-64), so a test has no way to control when the callback fires and must fall back on a real `Stopwatch`. The reason this was not already fixed with the repository's standard optional-`TimeProvider?` pattern (the precedent at UtilitiesCS/Threading/ThreadMonitor.cs lines 64-82) is a language constraint: that precedent is a *constructor*, and constructors are never converted to delegates. `WaitAsync` is converted to a delegate, at StoreRehookCoordinator.cs line 102. Per the C# standard's method-group-conversion rules, candidate methods are ignored if one or more of their optional parameters has no corresponding parameter in the target delegate type, so adding `TimeProvider? timeProvider = null` removes the only candidate and yields CS0123 at that line. Two explicit overloads restore an unambiguous 1-parameter candidate. (Research §1.1, §1.2, §1.6; numeric derivation §5 N1 established that there are exactly two production call sites and exactly one of them is a method-group conversion.) + +**Finding 2 — the reported site is orphan source, and the defect's real location is a sibling assembly (orphan-vs-compiled distinction).** `UtilitiesCS.Test.csproj` uses an explicit `` list with no wildcard include and no SDK-style implicit globbing, so presence on disk does not imply presence in the assembly. `ResourceTests.cs` and the three `Form` sources are on disk but absent from the csproj — a historical file move left the root copies stranded (the same pattern is visible for `SerializableListTest.cs` and `DeedleTests.cs`, which are compiled from their moved copies). The `ShowDialog()` calls the issue flags therefore cannot execute. The identical hygiene defect *is* live in `SVGControl.Test`, whose csproj compiles `Form1.cs` and `Form2.cs` (with `Form`) and embeds their `.resx` files, while no test in that assembly references either type. (Research §2.1, §2.2; numeric derivation §5 N2 and §5 N3.) + +**Finding 3 — the same orphan-vs-compiled distinction, plus a mis-identified shared resource.** `DASLFilterParser_Tests.cs` is byte-identical to `DASLFilterParserTests.cs` apart from namespace and class name, but only the latter appears in the csproj, so the "two classes conflicting" framing describes a conflict that cannot occur. The genuine hazard is that `DASLFilterParserTests.PrintTree_WritesIndentedTreeToConsole` captures `Console.Out`, installs a `StringWriter`, and restores the original — a mutation of process-global state — because the production method writes directly to the console with no injectable `TextWriter`. Under `[assembly: Parallelize(Workers = 0, Scope = ExecutionScope.ClassLevel)]` (UtilitiesCS.Test/Properties/AssemblyInfo.cs lines 18-21, which research §0 confirmed is live in CI because the CI vstest invocation passes no `/Settings:` argument), this class overlaps roughly thirty sibling classes that also call `Console.SetOut`. Two documented failure modes follow: (a) a sibling's redirect lands between capture and act, the `StringWriter` stays empty, and the assertion fails; (b) a sibling captures `Console.Out` while this test's `StringWriter` is installed and reinstalls it after the `using` has disposed it, making every later `Console.Write` in the process throw `ObjectDisposedException` — one interleaving cascading into unrelated failures. The repository already recognises this exact hazard and its remedy in two classes. (Research §3.1, §3.2, §3.3; numeric derivation §5 N4.) + +**Finding 4 — a harness timeout bound, not a wait (timeout-vs-wait distinction).** `PumpTimeoutMs` appears only as the argument of MSTest `[Timeout(...)]` attributes and never in a wait or expression position; the pump-hosted tests contain no `Thread.Sleep`, no `Task.Delay`, no `Stopwatch`, and no polling loop, so their logic already satisfies the determinism rule. The failure mode is narrower than non-determinism: under contention the *real elapsed cost of the work under test* — constructing real WinForms and WebView2 controls to the handle-created state — exceeds the 60 s bound and MSTest aborts an otherwise-correct test. Because the cost is real UI construction serviced by a real Win32 message loop, and because the production code reads its `SynchronizationContext` off the control it constructs rather than from an injected seam, no test-side substitution can remove it. (Research §4.1, §4.2, §4.3; numeric derivation §5 N5.) + +## Proposed Fix + +### Design summary (what changes where): + +Three independent, small changes, all test-side except one production seam: + +1. Split `WaitAsync` in `TaskMaster/AppGlobals/NonBlockingDelay.cs` into a 1-arg overload and a 2-arg `TimeProvider`-accepting overload, and rewrite `TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs` around `FakeTimeProvider`. +2. Remove every `Form`-derived type from the two affected unit-test assemblies and install the existing structural guard in each so the condition cannot return. +3. Move the two remaining `Console.Out`-capturing `UtilitiesCS.Test` classes into MSTest's serial partition with `[DoNotParallelize]`, and delete the orphan duplicate that would reintroduce the hazard if a contributor added it to the csproj. + +**`TaskMaster/AppGlobals/NonBlockingDelay.cs` is the only production (non-test) file this work touches.** It is touched because no seam exists yet and one cannot be created from the test side, which is precisely the exception the item brief allows: *test-only wherever possible, production seam only where a seam genuinely does not exist*. Every other change in this item is confined to test projects, test sources, or test project files. In particular, no production API is broadened, renamed, or removed: the 1-arg `WaitAsync` signature that existing callers bind to is unchanged. + +### Boundaries and invariants to preserve: + +- **`NonBlockingDelay` stays `internal static`.** No class-shape change; the `[assembly: InternalsVisibleTo("TaskMaster.Test")]` declarations already make it reachable from the test project. +- **The 1-arg `WaitAsync(TimeSpan)` overload must remain the unique 1-parameter candidate** so the method-group conversion at StoreRehookCoordinator.cs line 102 continues to bind to `Func` (no CS0123). No optional parameter may be introduced on either overload. +- **Preserve the `#nullable enable annotations` / `#nullable restore annotations` pragma pair at `NonBlockingDelay.cs:52-54`** (surrounding `Timer? timer = null`, together with the explanatory comment at lines 47-51). Removing or widening it re-emits CS8632 under the `TreatWarningsAsErrors` gate. The 2-arg overload's `ITimer? timer = null` local needs the same narrowly-scoped treatment. +- **Timer disposal and completion semantics are unchanged.** `ITimer` is `IDisposable`, so the existing `timer?.Dispose(); tcs.TrySetResult(true);` callback body carries over verbatim. `TaskCreationOptions.RunContinuationsAsynchronously` on the `TaskCompletionSource` must be retained — it is what prevents an `await` continuation from running inline on the thread calling `FakeTimeProvider.Advance`. +- **The structural guard is metadata-only.** It reflects over `Assembly.GetExecutingAssembly()` and never instantiates a type; the `ReflectionTypeLoadException` fallback must be carried over so the guard degrades to the loadable subset rather than turning permanently red for an unrelated load failure. +- **`[DoNotParallelize]` is additive and order-independent.** No test body, assertion, or test name changes for finding 3. +- **No production API seam for `DASLFilterParser.PrintTree`**; the console redirect stays at the test level. +- **No file under .claude/**, .codex/**, .agents/**, config/blast-radius.json, or config/orchestration-routing.json is touched. No file under `QuickFiler/` production sources is touched.** + +### Dependencies or blocked work: + +- The `packages/` directory is absent from this worktree, so `nuget restore` (or a restore-on-build) is a prerequisite before any build following the `packages.config` / `.csproj` edits (research §0). +- Issue #743 tracks Finding 4. It is a follow-up, not a blocker: #729 can be completed and merged independently. +- `QuickFiler/` production sources are held by a different parallel work item in this run; this item must not write into that footprint. + +### Implementation strategy (what changes, not sequencing): + +#### Files/modules to change: + +Reproduced from research §7 "Requirements Mapping", with the `SVGControl.Test` rows added per the in-scope decision recorded above. + +| File | Change | +|---|---| +| `TaskMaster/AppGlobals/NonBlockingDelay.cs` | Split `WaitAsync` into a 1-arg overload delegating to a new 2-arg `WaitAsync(TimeSpan, TimeProvider)`; replace `new Timer(...)` with `timeProvider.CreateTimer(...)` returning `ITimer`; preserve the lines 52-54 `#nullable ... annotations` pragma pair. **Only production file changed.** | +| `TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs` | Remove `Stopwatch` and the `System.Diagnostics` using; inject `FakeTimeProvider`; add the not-completed-before-`Advance` assertion; add one test covering the 1-arg overload | +| `TaskMaster.Test/TaskMaster.Test.csproj` | Two `Reference` blocks (research §1.5 supplies the verbatim text mirrored from UtilitiesCS.Test.csproj) | +| `TaskMaster.Test/packages.config` | Two `package` entries (research §1.5) | +| `UtilitiesCS.Test/ResourceTests.cs`, `UtilitiesCS.Test/Form1.cs`, `UtilitiesCS.Test/Form1.Designer.cs`, `UtilitiesCS.Test/Form1.resx`, `UtilitiesCS.Test/Form2.cs`, `UtilitiesCS.Test/Form2.Designer.cs`, `UtilitiesCS.Test/Form2.resx`, `UtilitiesCS.Test/Form3.cs`, `UtilitiesCS.Test/Form3.Designer.cs`, `UtilitiesCS.Test/Form3.resx` | Delete (orphan files; no csproj edit needed because none is referenced) | +| `UtilitiesCS.Test/NoLiveFormInTestAssemblyTests.cs` | New — ported guard, namespace `UtilitiesCS.Test` | +| `UtilitiesCS.Test/UtilitiesCS.Test.csproj` | Add the `` entry for the new guard | +| `UtilitiesCS.Test/OutlookObjects/Filter DASL/DASLFilterParserTests.cs` | Add `[DoNotParallelize]` + hazard comment | +| `UtilitiesCS.Test/ReusableTypeClasses/StackGeek_Tests.cs` | Add `[DoNotParallelize]` + hazard comment | +| `UtilitiesCS.Test/OutlookObjects/DASLFilterParser_Tests.cs` | Delete (orphan duplicate) | +| `SVGControl.Test/Form1.cs`, `SVGControl.Test/Form1.Designer.cs`, `SVGControl.Test/Form1.resx`, `SVGControl.Test/Form2.cs`, `SVGControl.Test/Form2.Designer.cs`, `SVGControl.Test/Form2.resx` | Delete (compiled, unreferenced live `Form` types — the only live violation of Finding 2) | +| `SVGControl.Test/SVGControl.Test.csproj` | Remove the `` entries for `Form1.cs`, `Form1.Designer.cs`, `Form2.cs`, `Form2.Designer.cs` and the `` entries for `Form1.resx`, `Form2.resx`; add the `` entry for the new guard | +| `SVGControl.Test/NoLiveFormInTestAssemblyTests.cs` | New — ported guard, namespace `SVGControl.Test`.

The 2-arg overload changes only *which* timer abstraction schedules the completion callback; the returned `Task`'s observable contract (completes once, after `delay`, on a thread-pool continuation) is identical. + +#### Error handling and logging updates: + +None. No new exception type, no new catch, no logging call is added or removed. The guard's `ReflectionTypeLoadException` fallback is carried over from the existing QuickFiler.Test source unchanged. + +#### Rollback/feature-flag considerations (if applicable): + +Not applicable. There is no runtime flag and no staged rollout. Rollback is a plain revert of the branch; the only production file involved retains a backward-compatible signature, so a revert cannot strand a caller. + +### Technical specifications (interfaces/contracts): + +#### Inputs/outputs and formats: + +- `public static Task WaitAsync(TimeSpan delay)` — unchanged contract: returns a task completing after `delay`, without blocking the caller and without requiring a running `Dispatcher`. Delegates to the 2-arg overload with `TimeProvider.System`. +- `public static Task WaitAsync(TimeSpan delay, TimeProvider timeProvider)` — same contract, with scheduling supplied by the caller's `TimeProvider`. `timeProvider.CreateTimer(callback, null, delay, Timeout.InfiniteTimeSpan)` returns an `ITimer` disposed inside the callback. +- The structural guard produces an ordered `string[]` of `Form`-assignable type full names from the executing assembly and asserts it is empty. + +#### Required configuration keys and defaults: + +None. `TimeProvider.System` is the default supplied by the 1-arg overload; no configuration key, environment variable, or runsettings entry is introduced. + +#### Backward-compatibility expectations: + +- No breaking change. Both production call sites of `WaitAsync` (research §5 N1 established there are exactly two: the method-group conversion at StoreRehookCoordinator.cs line 102 and the direct invocation at TaskMaster/AppGlobals/AppEvents.cs line 456) compile unchanged. +- No `.csproj` in the solution sets `DocumentationFile` or `GenerateDocumentationFile`, so CS0419 (ambiguous cref) cannot be emitted and the existing `` references remain valid despite the new overload (research §0). +- `ITimer` and `TimeProvider` are proven available on net481 in this repository by UtilitiesCS/Threading/ThreadMonitor.cs (lines 43 and 96-101). + +#### Performance constraints (latency/throughput/memory): + +- Production runtime cost is unchanged in practice: `TimeProvider.System.CreateTimer` wraps the same `System.Threading.Timer`, adding one small wrapper allocation per call. The helper is invoked on a retry path, not a hot path. +- Test-suite runtime improves: the rewritten `NonBlockingDelayTests` no longer spends real milliseconds waiting. `[DoNotParallelize]` on two classes moves them to MSTest's serial partition; the two classes are short and the effect on total assembly time is negligible relative to the flake risk removed. + +## Assumptions, Constraints, Dependencies +- Assumptions (environment, data, access): + - `nuget restore` can populate `packages/` in this worktree; the two new packages resolve at the pinned versions used by UtilitiesCS.Test. + - `FakeTimeProvider.Advance(TimeSpan.Zero)` wakes a zero-due-time waiter (research §1.4 read the upstream `WakeWaiters` implementation and found an inclusive comparison). If an actual run shows the comparison is strict, `Advance(TimeSpan.FromTicks(1))` is the equivalent fallback. This is the single point in the change that must be confirmed by executing the test rather than by reading source. + - The MSTest host remains pump-less, so the existing `SynchronizationContext.Current.Should().BeNull()` arrangement assertion stays valid. +- Constraints (budget, performance, compatibility): + - Bugfix minimal-change rule: no opportunistic refactors, no production API widening beyond the single seam. + - Test-only wherever possible; the one production file is justified above. + - net481 / legacy (non-SDK) project format: every new source file needs an explicit `` entry. + - File ownership: `QuickFiler/` production sources and the push-down-owned .claude/.codex/.agents/config paths are off-limits. +- External dependencies (services, libraries, releases): + - `Microsoft.Bcl.TimeProvider` 10.0.11 and `Microsoft.Extensions.TimeProvider.Testing` 10.9.0, both already in use by UtilitiesCS.Test. The testing package declares exactly one net462 dependency (`Microsoft.Bcl.TimeProvider >= 8.0.1`), satisfied by the 10.0.11 pin, so two package entries suffice (research §1.5). + +## Data / API / Config Impact +- User-facing or API changes: none. `NonBlockingDelay` is `internal`; the added overload is not part of any public surface. +- Data or migration considerations: none. +- Logging/telemetry updates (if any): none. +- Compatibility notes (CLI flags, config schemas, versioning): no CLI flag, runsettings, or config-schema change. CI's vstest invocation is unchanged, including its absence of a `/Settings:` argument — which is why `[DoNotParallelize]` (an in-source attribute) is the correct remedy rather than a runsettings edit. + +## Test Strategy + +Derived from research §8. + +**Finding 1 — rewrite in place, plus one added test.** Rewrite the two existing methods in `TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs`; do not leave a third variant of the old wall-clock test behind. Ordering is mandatory: `FakeTimeProvider.CreateTimer` does not invoke the callback at creation, so each test must **start the task, assert it has not completed, `Advance`, then `await`** (research §1.4). For `WaitAsync_WithNoDispatcher_CompletesAfterInterval` this is a strictly stronger assertion than the current `Stopwatch` check, because it proves the task cannot complete *early*, which elapsed-time assertion never did. For `WaitAsync_ZeroDelay_CompletesWithoutPump`, `Advance(TimeSpan.Zero)` is the expected trigger, with `Advance(TimeSpan.FromTicks(1))` as the documented fallback. Keep the existing `[Timeout(5000)]` attributes: after the fix they are a harness deadlock bound, not a wait. + +**Finding 1 — coverage of both overloads (condition from research §7 now resolved).** Research §7 flagged that a direct test of the 1-arg overload is needed *only if* `StoreRehookCoordinator`'s existing tests do not already exercise it transitively. That condition was checked on 2026-09-02: TaskMaster.Test/AppGlobals/StoreRehookCoordinatorTests.cs constructs the coordinator at lines 60 and 259 and **both call sites pass `_ => Task.CompletedTask` for the trailing `delay` parameter**, so the `delay ?? NonBlockingDelay.WaitAsync` fallback is never taken and the 1-arg body would be left uncovered. **A direct test of the 1-arg overload is therefore required**, otherwise coverage on changed production lines regresses. It should assert completion for a small real interval under the existing `[Timeout]` bound without asserting on elapsed time (a completion assertion, not a duration assertion, so no wall-clock dependency is reintroduced). + +**Finding 2 — one guard class per test assembly, metadata-only, no instantiation.** The status of the two guards differs and must be documented rather than conflated: +- `UtilitiesCS.Test/NoLiveFormInTestAssemblyTests.cs` is **green from birth**. Because the `Form` sources were never compiled into that assembly (research §2.1, §5 N2), it is regression *prevention*, not a fail-before/pass-after regression test. No red run exists or can be produced there, and no reviewer should expect one. Deleting the orphan sources rather than gutting the `[Ignore]`d method bodies is deliberate: gutting would leave `Form` sources on disk one csproj line away from re-entering the assembly. +- `SVGControl.Test/NoLiveFormInTestAssemblyTests.cs` is a **genuine red-before / green-after regression test** (research §2.2, §5 N3). The guard must be observed failing against the current csproj — naming the two `Form`-derived types — before the deletions, and passing after. That failing run is the fail-before evidence and is recorded under `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/regression-testing/`. + +**Finding 3 — attribute-only change, no new test, with a fail-before exception dossier.** The hazard is a race requiring a specific interleaving of `Console.SetOut` across two threads, so a deterministic red run is not producible. Record a fail-before exception dossier at `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/regression-testing/fail-before-exception..md` with a `WhyFailingRunImpossible` section stating that constraint, and cite the two in-repo precedent classes as the alternative proof that the hazard is real and was previously observed: UtilitiesCS.Test/HelperClasses/PrettyPrint_Tests.cs lines 14-20 and UtilitiesCS.Test/OutlookObjects/Table/OlTableExtensions_Tests.cs lines 17-21. The new hazard comments should reuse that precedent wording but cite UtilitiesCS.Test/Properties/AssemblyInfo.cs lines 18-21 as the live source of the parallel scope, because the precedent comments' reference to `TaskMaster.runsettings` is stale — CI passes no `/Settings:` argument, so the assembly-level attribute is what actually takes effect (research §0). + +**Finding 4 — no test change.** Out of scope; tracked by #743. + +- Regression tests to add or update: `TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs` (rewrite two, add one); `SVGControl.Test/NoLiveFormInTestAssemblyTests.cs` (new, red-before/green-after); `UtilitiesCS.Test/NoLiveFormInTestAssemblyTests.cs` (new, green-from-birth prevention guard). +- Unit tests for the fixed behavior and boundaries: `FakeTimeProvider`-driven completion for the 2-arg overload; direct completion test for the 1-arg overload; empty-`Form`-set assertion in both guard assemblies. +- Edge cases and negative scenarios: zero-length delay (`TimeSpan.Zero`); the not-completed-before-`Advance` negative assertion; `ReflectionTypeLoadException` degradation in the guard; the compile-time negative case that the method-group conversion at StoreRehookCoordinator.cs line 102 must not regress to CS0123. +- Error handling and logging verification: not applicable — no error-handling or logging behavior changes. +- Coverage impact and targets for changed lines/modules: `TaskMaster/AppGlobals/NonBlockingDelay.cs` is the only production file with changed covered lines; both overloads must be directly exercised so coverage on changed lines does not regress. Test-only files do not enter the production coverage denominator. +- Toolchain commands to run (format → lint → type-check → test): + 1. `nuget restore` (the `packages/` directory is absent from this worktree) + 2. `dotnet tool run csharpier format .` (verify with `dotnet tool run csharpier check .`) — note that CSharpier 1.2.6 formats `packages.config`, so this step will reformat the edited file and the loop must restart from step 1 when it does + 3. `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:EnableNETAnalyzers=true /p:EnforceCodeStyleInBuild=true` + 4. `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:TreatWarningsAsErrors=true` + 5. `vstest.console.exe /EnableCodeCoverage /InIsolation` +- Manual validation steps (if required): for the local test run, exclude `\.claude\` worktree copies from the discovered assembly list and pass `/InIsolation` to match CI; an empty failure message with sub-millisecond duration indicates an assembly-load problem, not a regression. + +## Acceptance Criteria + +- [ ] AC1 — `TaskMaster/AppGlobals/NonBlockingDelay.cs` declares both `public static Task WaitAsync(TimeSpan delay)` and `public static Task WaitAsync(TimeSpan delay, TimeProvider timeProvider)`, neither declaring an optional parameter, and the 1-arg overload delegates to the 2-arg overload passing `TimeProvider.System`. +- [ ] AC2 — The 2-arg overload schedules its one-shot completion via `timeProvider.CreateTimer(callback, null, delay, Timeout.InfiniteTimeSpan)` returning `ITimer` instead of `new System.Threading.Timer(...)`; the callback still disposes the timer and completes the `TaskCompletionSource`, and `TaskCreationOptions.RunContinuationsAsynchronously` is retained. +- [ ] AC3 — The `#nullable enable annotations` / `#nullable restore annotations` pragma pair around the nullable timer local in `TaskMaster/AppGlobals/NonBlockingDelay.cs` (at lines 52-54 before the change) is preserved, and the nullable-rebuild gate emits no CS8632 for that file. +- [ ] AC4 — The method-group conversion `_delay = delay ?? NonBlockingDelay.WaitAsync;` at TaskMaster/AppGlobals/StoreRehookCoordinator.cs line 102 and the direct invocation at TaskMaster/AppGlobals/AppEvents.cs line 456 both still compile with no CS0123 and no source change to either file. (These are the complete set of production call sites per research §5 N1: exactly two, exactly one of which is a method-group conversion.) +- [ ] AC5 — `TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs` contains no `Stopwatch` reference and no `System.Diagnostics` using directive; the rewritten `WaitAsync_WithNoDispatcher_CompletesAfterInterval` and `WaitAsync_ZeroDelay_CompletesWithoutPump` inject a `FakeTimeProvider`, assert the returned task is not completed before `Advance`, and complete after it. Both retain `[Timeout(5000)]` as a deadlock bound. +- [ ] AC6 — Both `WaitAsync` overloads are directly covered by `TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs`: the 2-arg overload via `FakeTimeProvider` and the 1-arg overload via a dedicated test asserting completion (not elapsed duration).

Mitigated by AC1 (no optional parameter on either overload) and AC4 (both call sites verified compiling), and detected by the mandatory `/t:Rebuild` gates. + - **`FakeTimeProvider` zero-delay semantics.** `Advance(TimeSpan.Zero)` is expected to wake a zero-due-time waiter based on reading the upstream `WakeWaiters` implementation, but this is the one behavior confirmed by source reading rather than by an executed run. Mitigated by the documented `Advance(TimeSpan.FromTicks(1))` fallback and by the fact that the test's `[Timeout(5000)]` converts a wrong assumption into a fast, unambiguous failure rather than a hang. + - **CS8632 from the nullable gate.** The 2-arg overload introduces a second nullable local. Mitigated by AC3's requirement to scope the `annotations`-only pragma pair the same way the existing code does. + - **`packages/` absent from the worktree.** A build attempted before `nuget restore` fails on the `` package-restore guards rather than on the change itself. Mitigated by making `nuget restore` the first toolchain step. + - **CSharpier reformats `packages.config`.** The formatter will rewrite the edited file, which under the repository's restart rule requires restarting the toolchain loop. Mitigated by expecting the restart rather than treating it as a failure. + - **Deleting `SVGControl.Test` forms breaks its build.** If the six file deletions and the csproj entry removals are not applied together, the project fails to compile on a missing source file. Mitigated by treating the deletion and the csproj edit as one indivisible change. + - **Coverage regression on changed production lines.** Mitigated by AC6's requirement that both overloads be directly covered. +- Mitigations and rollbacks: the change is a plain revert away from the pre-change state; no data, schema, or configuration migration is involved and the one production signature that existing callers bind to is unchanged. + +## Rollout & Follow-up +- Release/rollout steps: merge to main through the standard PR gate. No deployment, feature flag, or staged rollout is involved — the production change is an internal helper overload and everything else is test-side. +- Post-fix monitoring or clean-up tasks: + - Watch CI for any recurrence of an empty-captured-output or `ObjectDisposedException` failure in `UtilitiesCS.Test`, which would indicate a third unprotected `Console.Out`-capturing class was introduced after this change. + - UtilitiesCS.Test/HelperClasses/NLogTraceWriter_Test.cs remains a potential stale-writer-leak source (failure mode 2 only, no failing mode of its own).

Pump-hosted `QfcItemController`/`WebView2BreadcrumbHost` tests should complete deterministically regardless of CPU contention, either by scaling the harness bound to the environment or by allowing a synchronous fake to replace the real message pump for the members under test. + +## Actual Behavior + +Research performed under issue #729 (2026-09-02) confirmed: `PumpTimeoutMs` (declared 4 times across `QfcItemController.InitializationTests.cs:38`, `.SeamFactoryTests.cs:327`, `.ViewerSetupTests.cs:34`, `WebView2BreadcrumbHostTests.cs:25`) is used in exactly 19 places, all as the argument of an MSTest `[Timeout(...)]` attribute, and never as a wait/poll duration — the test logic itself contains no `Thread.Sleep`, `Task.Delay`, `Stopwatch`, or polling loop. The load-sensitivity is not a test-determinism defect in the MSTest-visible sense; it is that the *real elapsed cost* of constructing the production object graph under test can exceed the 60-second harness bound under contention. + +No test-only fix removes this, for four reasons documented in the #729 research artifact (`docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/research/research-729.2026-09-02T09-30.md`, section 4.2): + +1. `QuickFiler/Viewers/ItemViewer.cs:23-29` reads `SynchronizationContext.Current` and `Dispatcher.CurrentDispatcher` directly at construction (`_context = SynchronizationContext.Current;`), with no injectable seam; `UiSyncContext` (`ItemViewer.cs:59-62`, `IItemViewer.cs:37`) exposes it read-only. `QfcItemController.ViewerSetup.cs:64,320,331,336` await it directly. +2. The dominant fixture cost is a real WinForms control tree plus two handle-created `WebView2` children (`QfcItemController.InitializationTests.Part2.cs:74-84`), which only a real Win32 message loop can service — a fake `SynchronizationContext` cannot substitute for `Control.Handle`/`BeginInvoke` marshalling. +3. `[DoNotParallelize]` would be a no-op: `QuickFiler.Test` already runs serially (no `[assembly: Parallelize]`, CI passes no `/Settings:`). +4. Removing `[Timeout]` would trade a bounded, diagnosable failure for an unbounded CI hang on a genuine deadlock (documented rationale at `QfcItemController.InitializationTests.cs:33-37`). + +## Logs / Screenshots + +- [ ] Attached minimal logs or screenshot +- Snippet: each failure is recorded with an elapsed time of approximately 60 seconds and a `[Timeout]` message rather than an assertion-failure message, consistent with issue #711's original report. + +## Impact / Severity + +- [ ] Blocker +- [ ] High +- [x] Medium +- [ ] Low + +Medium: no incorrect production behavior; test-suite reliability/determinism debt that risks intermittent CI failures on a coverage-enabled or loaded runner, consistent with the closed #711 report this issue re-promotes. + +## Suspected Cause / Notes + +Root cause: `QuickFiler/Viewers/ItemViewer.cs` and the `QfcItemController` members it backs have no injectable UI-marshalling abstraction (an `IUiDispatcher`/`SynchronizationContext` seam, or an interface over the `WebView2` control accepted by `WebView2BreadcrumbHost`'s constructor). Until such a seam exists, the pump-hosted tests must construct real WinForms/WebView2 objects and are therefore coupled to real message-pump timing. This is a `QuickFiler/` production-code change, which was out of scope for issue #729 (test-only item; `QuickFiler/` production sources are owned by a different parallel work item in that run). + +## Proposed Fix / Validation Ideas + +- [ ] Give `QfcItemController`/`ItemViewer` an injectable `IUiDispatcher` (or equivalent `SynchronizationContext` provider) seam so tests can substitute a synchronous fake instead of relying on a live message pump. +- [ ] Introduce an interface over the `WebView2` control that `WebView2BreadcrumbHost` accepts via constructor injection, so its handle-creation cost is not incurred in pump-hosted unit tests. +- [ ] Once a seam exists, re-evaluate whether `PumpTimeoutMs = 60000` can be lowered, since the remaining wait would then be a controllable fake rather than a real Win32 message loop. +- [ ] Do not remove `[Timeout(PumpTimeoutMs)]` outright; it is a documented deadlock guard, not the load-sensitivity source. + +## Next Step + +- [ ] Promote to GitHub issue (bug-report template) +- [ ] Move to active fix folder / branch From 50d0f39a57a616c85f87ad7a3ee088be9bc83ce1 Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Wed, 2 Sep 2026 17:28:55 -0400 Subject: [PATCH 02/10] docs(729): revise spec/plan write-set presentation for blast-radius harvester compatibility Preparation-mode revision on issue #729's already-prepared plan: the downstream parallel-scheduler blast-radius harvester reads every backtick-delimited path token in spec.md/plan.md as a write target regardless of surrounding context (exclusion, model-reference, or read-only citation). This caused three problems: (1) scope-exclusion mentions of .claude/**, .codex/**, .agents/**, config/blast-radius.json, config/orchestration-routing.json, and QuickFiler/ were read as write targets, causing false contention with every sibling item in the 13-item parallel run; (2) the QuickFiler.Test structural-guard file cited as the ported model was read as a QuickFiler.Test write, mis-assigning module membership; (3) the DASL parser test path's space in "Filter DASL" defeats a whitespace-splitting extractor. Adds a new "## Write Set" section to spec.md enumerating the 27 paths this plan's diff actually creates, modifies, or deletes (annotating the DASL parser test path as containing a space), and removes backticks from every narrative mention of an exclusion, model-to-copy, or read-only citation throughout both documents, across thirteen revision rounds each re-validated by atomic-executor preflight. No task, acceptance criterion, command, evidence path, or Decisions Record substance was changed; this is a text-presentation-only revision. Final preflight: PREFLIGHT: ALL CLEAR / CONVERGENCE: NO FURTHER ROUNDS EXPECTED (round 13).

Run a case-insensitive search over every file under `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729` for four things. The first three are fixed-string searches: the account name, derived as `Split-Path -Leaf $env:USERPROFILE`; the machine name, read from `$env:COMPUTERNAME`; and the absolute workspace-root prefix, derived at run time as `(Resolve-Path .).Path`. The fourth is a pattern search rather than a fixed-string search and serves as a residual detector only: a single ASCII letter immediately followed by the two-character drive-root sequence, that sequence constructed at run time as `([string][char]58 + [string][char]92)` so that neither this plan nor this task's own artifact contains the literal. The letter-anchored form is required because the bare two-character sequence occurs three times inside the swept file set in non-host-path contexts — twice in this plan file, where it is preceded by a straight quote and by a backtick, and once in the research artifact inside a regular-expression literal, where it is preceded by an asterisk. Rewriting any of the three would corrupt a recorded acceptance command or a research citation, and leaving them would make the acceptance below unreachable. The letter-anchored form matches none of the three and still matches every genuine absolute path. Replace every workspace-root-prefix hit with `` in its entirety — the whole absolute prefix, never only its drive-root characters, because substituting two characters inside an absolute path drives the residual count to zero while leaving the remainder of that path disclosed — and replace every account-name hit with `` and every machine-name hit with ``, using the XML-escaped forms in any `.xml`, `.cobertura.xml`, `.trx`, or `.coveragexml` artifact, because those placeholders contain angle brackets that would otherwise make the document ill-formed, and re-parse every rewritten XML-family file with `[xml](Get-Content -Raw -Encoding UTF8 $path)` to confirm it is still well-formed. After those three substitutions have been applied, replace every remaining letter-anchored absolute path — the whole path token, from its drive letter to the end of the path — with ``, using the XML-escaped form in any XML-family artifact and re-parsing it afterwards on the same terms. This fourth substitution is required because a raw, unprocessed Cobertura artifact carries third-party build-machine source paths that lie outside the workspace root and are therefore untouched by the workspace-root-prefix substitution, while still being matched by the letter-anchored residual detector: the raw dotnet-coverage output for this solution embeds `Mono.Reflection` source paths rooted at a drive-level `sources` directory. Three raw Cobertura artifacts already committed under `docs/features/active/` in this repository exhibit exactly that — `docs/features/active/2026-08-07-efcviewer-missing-lineage-and-segment-navigation-439/evidence/qa-gates/issue-439-final.cobertura.xml`, `docs/features/active/2026-08-25-quickfiler-high-confidence-partial-screen-backfill-608/evidence/qa-gates/r1-csharp-coverage.2026-08-25T12-33.cobertura.xml`, and `docs/features/active/2026-08-25-quickfiler-high-confidence-partial-screen-backfill-608/evidence/baseline/r3-csharp-coverage.2026-08-25T13-32.cobertura.xml` — each carrying 2,114 lines that the letter-anchored detector matches, of which 15 lines per artifact are the drive-level `sources` third-party paths that lie outside any workspace root and that the workspace-root-prefix substitution therefore cannot reach. A processed Cobertura carries no such path, because `scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1` lines 417-424 remove every non-allowlisted `` and rewrite each retained `class/@filename` to a repository-relative path, so this fourth substitution is a no-op there; every other `*.cobertura.xml` committed under `docs/features/active/` returns zero letter-anchored matches, which confirms it empirically. The fourth substitution is load-bearing only when `CoberturaProcessingState:` is `raw`, which P0-T11 and P6-T5 both explicitly authorize. Without it, `ResidualMatchCount: 0` is unreachable on a plan-authorized execution path. The two Cobertura artifacts are the expected rewrite targets, because dotnet-coverage writes absolute `` and `filename` values into them; both have already been read by P6-T6, which runs earlier, so no later task depends on their pre-substitution content. Record only the post-substitution values; do not quote the pre-substitution values in the evidence artifact itself, and do not spell the account name, the machine name, the absolute workspace-root prefix, or the two-character drive-root sequence literally in it. Rewrites land on files that earlier phase commits already committed, so they are staged and committed by P8-T22's directory-level `git add`.

Round 10's own note had rationalized leaving two of these in place on the theory that a path-plus-trailing-text span is not a bare whitespace-free token; that theory does not hold, since a whitespace-splitting extractor still isolates the leading path segment as its own token regardless of what non-whitespace-adjacent text follows inside the same backtick pair. All four X-entries are corrected in place: the backtick pair around each parenthetical excerpt is removed, leaving the excerpt as plain prose, matching the style already used elsewhere in this same paragraph for a citation excerpt that names a path with no single dedicated backtick span of its own. No task, phase, acceptance criterion, evidence path, git command, or Decisions Record substantive content is altered in this round. Applied directly by the orchestrator, consistent with round 12.

Fixed in spec.md at four locations (the Dependencies-or-blocked-work bullet, the toolchain-commands list step 2, AC18, and the CSharpier-reformats risk bullet): each removed the backtick pair around a bare, unqualified mention of the same short filename token that names one of the ten read-only paths' final path segment, leaving every other backtick on those same lines (including any directory-qualified mention of the genuine write-target file this plan actually edits) untouched. Fixed in plan.2026-09-02T08-59.md: the round-7 W3 self-review entry, which had claimed two specific short-form mentions in line 29 (Scope Recap, Finding 3) remained backtick-wrapped, was stale — round 10 had already removed both of those backtick pairs without updating W3's own description of them.

This entry's own text was checked before finalizing for a backtick immediately adjacent to any of the ten read-only paths or their bare/short forms; none was found, and this entry avoids repeating those forms as literal tokens at all, referring to each fix by its location and nature instead, precisely to close the recursive-reintroduction pattern that affected rounds 7, 8, 9, 10, and 11's own new prose in turn. + +Revision round 11 — this round fixes the five residual backtick-adjacency defects reported by the round-10 confirming preflight pass, all located in self-review narrative text that documented an earlier round's own fix.

Fixed: line 749, a round-7 sibling-region bullet, removing the backticks around the same bare DASLFilterParser.cs mention this bullet used to describe the file converted in W1 and W6. No task, phase, acceptance criterion, evidence path, git command, or Decisions Record substantive content is altered in this round; each fix is a same-line backtick-delimiter removal that adds or removes no line at its own location. This entry is inserted above the round-10 entry per the contract's append-only, newest-round-first convention and therefore shifts every line at or below the insertion point downward by four lines; the Planner Internal Review Record's own CITATION, AC-INVENTORY, and AC-MAPPING declarations move position accordingly but their content is unaffected, since none of them cites a line number inside this file's own self-review section. Every internal line-number citation that rounds 6 through 10 recorded for their own self-review entries (the Z1/Z2, Y1-Y7, X1-X4, and W7-W10 line pointers) is now stale by that same four-line amount and is not corrected in this pass, consistent with the round-8/9/10 precedent that each round corrects only its own citations in the same pass that introduces them. + +Before finalizing, this entry's own text was searched for a backtick immediately followed by any of the ten path strings or their bare/short forms (app.config, AssemblyInfo.cs, StoreRehookCoordinator.cs, DASLFilterParser.cs, AppEvents.cs, TaskMaster.csproj, packages.config, PrettyPrint_Tests.cs, OlTableExtensions_Tests.cs, NLogTraceWriter_Test.cs); no such sequence was found, so this entry is not itself a sixth instance of the defect it reports. This is the check that every one of the four prior rounds' own fix-describing entries omitted. + +Revision round 10 — citations re-derived directly against the current working tree in *this* revision pass. This round closes the recurring self-review-narrative backtick defect that rounds 7, 8, and 9 each reintroduced while fixing an instance of it elsewhere: round 7's own W1, W2, W3, W4, W5, W7, W8, W9, and W10 entries, round 8's own X1 entry, and round 9's own Y1 and Y3-Y6 entries — each written to document a fix that removed backticks from a bare mention of one of the ten read-only paths this plan never writes — themselves re-quoted one or more of those same ten paths inside backticks, one paragraph away from the fix each entry describes. This round removes every remaining backtick pair wrapping a bare, unqualified mention of one of the ten paths across every self-review entry, matching the plain-prose model W6 already used. A repository-wide adjacent-backtick search for each of the ten paths, run against the current tree after this round's edits, returns zero matches in this file and in spec.md. This round also removes backticks from two mentions outside the self-review section, identified separately from the ten-path sweep: the short-form AssemblyInfo.cs and TaskMaster.runsettings mentions in this file's Scope Recap Finding 3 paragraph, and the TaskMaster.runsettings mention in spec.md's Finding 3 Test Strategy paragraph — neither is one of the ten read-only paths, but both are stale or misleading citations the round-10 delegation identified for the same backtick-removal treatment. No task, phase, acceptance criterion, evidence path, git command, or Decisions Record substantive content is altered in this round; every edit removes only backtick delimiter characters from an already-correct narrative-prose word sequence and adds or removes no line at its own location. This entry, inserted above the round-9 entry per the contract's append-only rule, is new text and therefore shifts every line at or below the insertion point by a fixed amount; Z1 and Z2 below re-derive the shifted line numbers for the entries this round corrects, in their post-insertion final state, following the round-8/round-9 recursive-shift precedent. + +Z1. plan.2026-09-02T08-59.md — round-9 entries corrected in this round, re-read as the last step of this pass, after every insertion this round makes is already in place: Y1 (now at line 680) had four bare backtick-wrapped path mentions removed — TaskMaster/AppGlobals/StoreRehookCoordinator.cs, TaskMaster/AppGlobals/AppEvents.cs, TaskMaster/TaskMaster.csproj, and UtilitiesCS.Test/Properties/AssemblyInfo.cs; Y3 (now at line 684) had two removed — UtilitiesCS.Test/HelperClasses/PrettyPrint_Tests.cs and UtilitiesCS.Test/OutlookObjects/Table/OlTableExtensions_Tests.cs; Y4, Y5, and Y6 (now at lines 686, 688, 690) each had one removed — UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs. Y2 (now at line 682) and Y7 (now at line 692) were re-read and confirmed to already carry no bare backtick-wrapped mention of any of the ten paths, so neither was edited. + +Z2. plan.2026-09-02T08-59.md — round-7 and round-8 entries corrected in this round, re-read as the last step of this pass: W1 (now at line 727) had one removed, the AC17 production-file mention UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs; W2 and W4 (now at lines 729 and 733) each had one removed, the TaskMaster/AppGlobals/StoreRehookCoordinator.cs mention; W3 (now at line 731) had one removed, the full-path UtilitiesCS.Test/Properties/AssemblyInfo.cs mention, leaving its own already-deliberate short-form AssemblyInfo.cs and TaskMaster.runsettings mentions untouched per its own stated exemption; W5 (now at line 735) had two removed, the TaskMaster/TaskMaster.csproj and TaskMaster/packages.config mentions; W7 (now at line 739) had four removed, the TaskMaster/AppGlobals/StoreRehookCoordinator.cs, TaskMaster/AppGlobals/AppEvents.cs, TaskMaster/TaskMaster.csproj, and TaskMaster/packages.config mentions; W8 (now at line 741) had one removed, the TaskMaster.Test/app.config mention; W9 (now at line 743) had three removed, the UtilitiesCS.Test/Properties/AssemblyInfo.cs, UtilitiesCS.Test/HelperClasses/PrettyPrint_Tests.cs, and UtilitiesCS.Test/OutlookObjects/Table/OlTableExtensions_Tests.cs mentions; W10 (now at line 745) had its full-path UtilitiesCS.Test/HelperClasses/NLogTraceWriter_Test.cs mention removed, leaving its short-form StoreRehookCoordinator.cs mention untouched for the same reason W3 leaves its own short-form mention untouched; X1 (now at line 706) had two bare mentions removed from its citation-list-item-6 excerpt, the TaskMaster/TaskMaster.csproj and TaskMaster/packages.config mentions, leaving its item-4 and item-5 excerpts untouched because each of those backtick spans also carries trailing line-reference text and is not a bare whitespace-free path token by itself. W6 (now at line 737) was re-read and confirmed unchanged: it already models the plain-prose form every correction in this round now matches. + +Sibling-region re-checks performed in revision round 10: + +- Around every genuine write-target and code-identifier backtick left untouched in each corrected entry: each was re-read after this round's edits and confirmed byte-for-byte unchanged, because every edit in this round targeted only the exact bare ten-path token spans named in Z1 and Z2 and none of them matched or altered any other backtick span in the same sentence. +- Around P0-T13, P1-T5, P5-T7, P6-T2, P6-T8, P7-T1, and P8-T21 — the actual task text the Y-entries and W-entries describe: each was re-read in this pass and confirmed to already carry the ten paths as bare, unbackticked narrative prose, unchanged by this round. The defect this round closes existed only in the self-review narrative describing those tasks' earlier fixes, never in the tasks themselves. +- Around Scope Recap Finding 1 (line 25) and Finding 3 (line 29), and D1 (line 39) and D3 (line 41): re-read after this round's edits. Finding 1's and D1's TaskMaster/AppGlobals/StoreRehookCoordinator.cs mentions and D3's TaskMaster/TaskMaster.csproj and TaskMaster/packages.config mentions were already plain prose before this round, unchanged; Finding 3's full-path UtilitiesCS.Test/Properties/AssemblyInfo.cs mention was already plain prose, unchanged; only Finding 3's short-form AssemblyInfo.cs mention and its two TaskMaster.runsettings mentions lost their backticks this round. +- Around spec.md's Finding 3 Test Strategy paragraph (line 237) and its sibling AC17 mention (line 272, already unbackticked since round 7): re-read after this round's edit; the TaskMaster.runsettings mention lost its backticks and the surrounding sentence's `/Settings:` backtick and the AC17 mention are unchanged. +- Recursive-shift check on this round's own insertion — this round's own paragraph and entries Z1-Z2, inserted above the round-9 entry, shifted every citation below the insertion point downward by the same fixed amount (17 lines, once this bullet's own addition is included); Z1 and Z2 were re-read and their line citations corrected only after every insertion this round makes was already final, matching the round-8/round-9 recursive-shift precedent. The Planner Internal Review Record's CITATION-TO-TREE, AC-TRACEABILITY, and SCOPE-BOUNDARY declarations move from lines 896-898 to lines 913-915, AC-INVENTORY moves from line 945 to line 962, and UNRESOLVED-GAPS moves from line 969 to line 986; none of their content changed, only their physical position, because this round's insertion adds text only above them and edits no AC-MAPPING, CITATION, or inventory line. +- Self-check of this round's own new text against the rule it enforces — this paragraph, Z1, Z2, and every bullet above were re-read in full after being drafted to confirm that no bare backtick-wrapped mention of any of the ten paths appears anywhere in them. Every one of the ten paths named above appears as plain, unbackticked prose throughout this entry; none is wrapped in backticks. This is the same failure mode rounds 7 and 9 introduced in their own fix-describing entries, and this entry does not reintroduce it. +- Around the header fields (Last Updated, Status, Version): updated to reflect round 10, continuing the existing numbering convention from round 9's 2026-09-02T17-15 / "revision round 9" / 1.8. +- Recognized residual effect on rounds 6-9's own internal line citations, not corrected in this pass: this round's 17-line insertion shifts every citation-list line number, sibling-region bullet line number, and Y7's own AC-MAPPING line citation (962) that rounds 6 through 9 stated for their own re-derivation passes to a value 17 lines lower than what those entries still read. Per this round's explicit scope, only the eleven named entries receive an edit, and each of those edits is limited to the backtick removal specified; no citation inside Y7, W7, W8, W9, W10, X1, X2, X3, or X4 is corrected in this pass, and each remains at the value valid as of the round in which it was written rather than the value valid now. This is the same staleness mechanism round 8 corrected for round 7's citations; a future round may need to repeat that correction for the citations this round's insertion made stale. + +Revision round 9 — citations re-derived directly against the current working tree in *this* revision pass. This round corrects two defects reported by the round-8 confirming preflight pass: six residual backticked citations of files this plan never writes, sitting in task-prose lead sentences and acceptance-clause prose rather than in git/Select-String command spans, plus one AC-MAPPING `EVIDENCE:` field inconsistency for AC16. No task, phase, acceptance criterion, evidence path, git command, or Decisions Record substantive content is altered in this round; each of the eight corrections is itself a same-line substitution — a backtick-delimiter removal on an existing narrative-prose mention, or a single-token substitution inside an existing AC-MAPPING line — that adds or removes no line at its own location. This self-review entry, appended above the Planner Internal Review Record per the contract's append-only rule, is new text and therefore does shift every line at or below the insertion point; Y7 and the sibling-region bullets below re-derive the Planner Internal Review Record's line numbers against this pass's final state, following the round-8 recursive-shift precedent (X6). + +Y1. `plan.2026-09-02T08-59.md` line 548 (P0-T13) — re-read after editing. Of the twelve anchors P0-T13 re-verifies, four are now unbackticked because they are read-only citation targets, not write targets: TaskMaster/AppGlobals/StoreRehookCoordinator.cs (line 102 anchor), TaskMaster/AppGlobals/AppEvents.cs (line 456 anchor), TaskMaster/TaskMaster.csproj (line 148 anchor), and UtilitiesCS.Test/Properties/AssemblyInfo.cs (lines 18-21 anchor). The other eight anchors in the same list — both `TaskMaster/AppGlobals/NonBlockingDelay.cs` mentions (lines 42 and 52-54), `TaskMaster.Test/packages.config` (line 17), `TaskMaster.Test/TaskMaster.Test.csproj` (line 73), both `SVGControl.Test/SVGControl.Test.csproj` mentions (lines 55-66 and 86-91), `UtilitiesCS.Test/UtilitiesCS.Test.csproj` (line 76), and `UtilitiesCS.Test/OutlookObjects/Filter DASL/DASLFilterParserTests.cs` (line 8) — are genuine write targets or the compiled test file this plan modifies, and are confirmed still backticked and byte-for-byte unchanged after this round's edit. + +Y2. `plan.2026-09-02T08-59.md` line 558 (P1-T5) — re-read after editing. The lead sentence "Confirm TaskMaster.Test/app.config was not modified by P1-T3 or P1-T4." is now unbackticked. The two later occurrences of the same path, inside the `git diff --name-only $base HEAD -- TaskMaster.Test/app.config` and `git status --porcelain -- TaskMaster.Test/app.config` command spans, are confirmed still backticked and byte-for-byte unchanged — those are command arguments, not narrative prose, and were explicitly out of scope for this sweep. + +Y3. `plan.2026-09-02T08-59.md` line 602 (P5-T7) — re-read after editing. The two precedent/context citations UtilitiesCS.Test/HelperClasses/PrettyPrint_Tests.cs (lines 14-20) and UtilitiesCS.Test/OutlookObjects/Table/OlTableExtensions_Tests.cs (lines 17-21) are now unbackticked; the rest of the sentence, including the `WhyFailingRunImpossible:` field name and the artifact path, is unchanged. + +Y4. `plan.2026-09-02T08-59.md` line 608 (P6-T2) — re-read after editing. The acceptance-clause mention UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs (the production DASL parser file this plan verifies is unmodified) is now unbackticked; the sentence's other backticked spans (`EXIT_CODE: 0`, `Baseline unformatted set:`) are unchanged. + +Y5. `plan.2026-09-02T08-59.md` line 614 (P6-T8) — re-read after editing. The same UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs mention in this task's acceptance-clause prose is now unbackticked; the sentence's `RewrittenFileCount:` and `Baseline unformatted set:` backticks are unchanged. + +Y6. `plan.2026-09-02T08-59.md` line 652 (P8-T21) — re-read after editing. The same UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs mention in this task's acceptance-clause prose is now unbackticked; the sentence's `FailedCount:` and `csharpier check` backticks are unchanged. + +Y7. `plan.2026-09-02T08-59.md` — re-read as the last step of this pass, after this round's own paragraph and Y1-Y6 entries were already inserted above the Planner Internal Review Record, so the record's line numbers reflect this pass's final state rather than an intermediate one. The AC-MAPPING block's AC16 line is now at line 962: `AC-MAPPING: AC16 | IMPLEMENTATION: P7-T7 | TESTS: P8-T16 | EVIDENCE: P0-T2` is corrected to `AC-MAPPING: AC16 | IMPLEMENTATION: P7-T7 | TESTS: P8-T16 | EVIDENCE: P8-T16`, matching the pattern every other AC-MAPPING entry follows (`EVIDENCE:` names the AC's own verify-and-check-off task in Phase 8). `IMPLEMENTATION: P7-T7` and `TESTS: P8-T16` are unchanged. P8-T16, at line 647 (unaffected by this round's insertion, which sits below it in the file), is confirmed to be the task that performs and records AC16's verification. + +Sibling-region re-checks performed in revision round 9: + +- Around P0-T13's other eight anchors (line 548): each was re-read in this pass and confirmed to remain backticked exactly as before this round; none of the six corrections in this round matched or altered any of the eight. +- Around P1-T5's two command-span occurrences (line 558): both were re-read in this pass and confirmed to remain backticked exactly as before this round; the `$base` value and the `using the` clause following them are unchanged. +- Around the DASL parser TEST file `UtilitiesCS.Test/OutlookObjects/Filter DASL/DASLFilterParserTests.cs` (distinct from the production DASLFilterParser.cs corrected in Y4-Y6 only by the trailing `Tests` in the filename and the containing `Filter DASL` directory space): every occurrence in the plan — line 66's file-write inventory bullet, line 486's Block I heading, line 548's P0-T13 anchor, lines 596 and 603's P5-T1/P5-T8 task text, line 831's citation-list entry 18, line 850's sibling-region bullet, line 862's sibling-region bullet, and line 888's CITATION line — was re-read in this pass and confirmed still backticked and byte-for-byte unchanged. +- Around the other 20 AC-MAPPING entries, re-located after this round's own insertion to lines 947-961 and 963-967: each was re-read in this pass and confirmed unchanged in `IMPLEMENTATION:`, `TESTS:`, and `EVIDENCE:` fields, task ID, and ordering; only AC16's `EVIDENCE:` field was touched. +- Around the CITATION-TO-TREE, AC-TRACEABILITY, SCOPE-BOUNDARY declarations (re-located to lines 896-898) and the AC-INVENTORY declaration (re-located to line 945), and the remaining 43 CITATION lines: re-read in this pass and confirmed unchanged, because this round's seven edits touch only backtick delimiters on narrative prose and one AC-MAPPING `EVIDENCE:` token, none of which is a CITATION line, an inventory ID, or a tracked declaration. +- Recursive-shift check on this round's own insertion — this round's own paragraph and entries Y1-Y7, inserted into the `## Planner Adversarial Self-Review` section above the Planner Internal Review Record, shifted every citation below the insertion point downward by the same fixed amount; Y7 and the two bullets above it were re-read and corrected only after every insertion this round makes was already final, so the line numbers they carry are the values that hold once this pass stops adding lines, matching the round-8 precedent (X6) for a text-insertion pass. +- Around the header fields (`Last Updated`, `Status`, `Version`): updated to `2026-09-02T17-15`, "Ready for Preflight (revision round 9)", and `1.8` respectively, continuing the existing numbering convention from round 8's `2026-09-02T16-30` / "revision round 8" / `1.7`. + +Revision round 8 — citations re-derived directly against the current working tree in *this* revision pass. This round corrects two preflight-reported line-citation defects left by revision round 7: round 7 inserted a new paragraph and five numbered `W`-entries into the `## Planner Adversarial Self-Review` section, which shifted the numbered "Citations re-derived directly against the working tree" list (originally authored in the round-1 pass) and its sibling-region bullets downward by the same fixed amount, but round 7's own W7-W10 entries cited those locations' *pre-insertion* line numbers instead of re-deriving them against the post-insertion state. This round also corrects one line-range error in the Planner Internal Review Record's CITATION line for the `spec.md` `## Write Set` section, which cited an off-by-one upper bound. No task, phase, acceptance criterion, evidence path, git command, or Decisions Record substantive content is altered in this round; every edit is a numeral-only substitution inside an existing citation line. + +X1. `plan.2026-09-02T08-59.md` — re-read in full with a line-numbered tool as the last step of this pass, after every insertion this round makes is already in place. Citation-list item 4 (TaskMaster/AppGlobals/StoreRehookCoordinator.cs — line 102 ...) is at line 817, item 5 (TaskMaster/AppGlobals/AppEvents.cs — line 456 ...) is at line 818, and item 6 (TaskMaster/TaskMaster.csproj / TaskMaster/packages.config reference/package entries) is at line 819. W7 is corrected to cite lines 817-819. The content at each corrected line number is unchanged from what W7 already described; only the line numbers were stale. + +X2. `plan.2026-09-02T08-59.md` — re-read as the last step of this pass. Citation-list item 11 (TaskMaster.Test/app.config — lines 267-271 ...) is at line 824. W8 is corrected to cite line 824. + +X3. `plan.2026-09-02T08-59.md` — re-read as the last step of this pass. Citation-list item 20 (UtilitiesCS.Test/Properties/AssemblyInfo.cs — lines 18-21 ...) is at line 833, item 21 (UtilitiesCS.Test/HelperClasses/PrettyPrint_Tests.cs — lines 14-20 ...) is at line 834, and item 22 (UtilitiesCS.Test/OutlookObjects/Table/OlTableExtensions_Tests.cs — lines 17-21 ...) is at line 835. W9 is corrected to cite lines 833-835. + +X4. `plan.2026-09-02T08-59.md` — re-read as the last step of this pass. The two sibling-region re-check bullets W10 refers to are at line 858 (Around StoreRehookCoordinator.cs line 102: the sibling XML doc at line 72 carries ...) and line 861 (Around the two Finding 3 classes: UtilitiesCS.Test/HelperClasses/NLogTraceWriter_Test.cs also captures ...). W10 is corrected to cite lines 858 and 861. + +X5. `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` — re-read in full in this pass with a line-numbered tool; the file carries exactly 332 lines total, confirmed independently of the preflight reviewer's report. The `## Write Set` section heading is at line 302 and the section's final content line, the last backticked bullet `` `SVGControl.Test/Form2.resx` ``, is at line 332 — the file's last line. The Planner Internal Review Record's CITATION line for this section is corrected from "lines 302-333" to "lines 302-332". + +X6. Recursive-shift check on this round's own insertion — this round's own paragraph and entries X1-X5, inserted into the `## Planner Adversarial Self-Review` section, sit above the citation list and its sibling bullets, so drafting and then re-numbering this entry itself shifted those same locations again within this one pass, more than once, until no further text was added below the last numbered entry. X1-X4 above were re-read and corrected only after every insertion this round makes was already final, so the values they and W7-W10 now carry are the values that hold once this pass stops adding lines, not an intermediate value from mid-pass. This entry (X6) and the sibling-region bullets immediately below add no further line once written, so no additional shift follows this correction. + +Sibling-region re-checks performed in revision round 8: + +- Around each of the five numeral-only substitutions this round makes (the four in W7-W10 and the one in the spec.md CITATION line): each substitution replaces only the digits inside an existing citation line and adds or removes no line, no word, and no punctuation outside that numeral span, so no line below any of the five edited lines shifts as a result of this round's own edits. This is the sibling-region check the round-7 pass skipped for its own insertion: a text-insertion pass (round 7's new paragraph and five W-entries) shifts every line below it and therefore obligates re-derivation of every downstream citation in the same pass, whereas a pure line-number substitution (this round) does not, because it changes character content on an existing line without changing the document's line count. +- Around citation-list items 4-6, 11, and 20-22 and the two sibling-region bullets at lines 858 and 861: each was re-read in this pass and its described content (file path, line-range, and quoted snippet) matches exactly what W7-W10 already asserted before this round; only the outer line-number citation naming that content was stale. No content-level defect was found at any of the seven relocated citations. +- Around the Planner Internal Review Record's other 43 CITATION lines (every `CITATION:` line in the record except the one corrected at line 917), the `AC-INVENTORY:` block, and all 21 `AC-MAPPING:` entries: re-read in this pass and confirmed unchanged, because this round's spec.md CITATION-line fix touches only the line-range numerals on one CITATION line and no AC identifier, task ID, or mapping triple. +- Around the `## Write Set` section itself (`spec.md` lines 302-332): re-read in this pass; its 27 bullets, the section heading, and the preceding `## Rollout & Follow-up` content at lines 1-301 are unchanged from round 6/round 7's state, confirming the round-8 CITATION-line fix is a citation correction only and not a content edit to `spec.md`. + +Revision round 7 — citations re-derived directly against the current working tree in *this* revision pass. This round is a second, narrower semantics-preserving, text-presentation-only pass closing a residual gap left by revision round 6's blast-radius-harvester fix: ten path mentions that are read-only, verified-unmodified, or precedent/context citations (never write targets) were still backticked in narrative prose. No task, phase, acceptance criterion, evidence path, git command, or Decisions Record substantive content was altered; only backtick delimiters were removed from the ten specific non-write mentions enumerated below, plus one path in `spec.md`'s AC17. + +W1. `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` line 272 — re-read after editing. AC17's file-path mention UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs is now unbackticked; the two code-identifier backticks on `` `PrintTree` `` and `` `TextWriter` `` immediately following it are unchanged, confirming the edit did not over-reach into the identifier spans it was instructed to leave alone. + +W2. `plan.2026-09-02T08-59.md` line 25 (Scope Recap, Finding 1) — re-read after editing. TaskMaster/AppGlobals/StoreRehookCoordinator.cs is now unbackticked; the surrounding sentence's other backticked spans (`` `TimeProvider` ``, `` `TaskMaster/AppGlobals/NonBlockingDelay.cs` ``, `` `WaitAsync` ``, `` `TimeProvider? = null` ``) are unchanged, all of which are either a genuine write target or a code identifier, not a target of this round. + +W3. `plan.2026-09-02T08-59.md` line 29 (Scope Recap, Finding 3) — re-read after editing. UtilitiesCS.Test/Properties/AssemblyInfo.cs is now unbackticked. Re-derived against the current tree in this pass rather than carried forward: the sentence's `` `Console.Out` `` backtick is unchanged (a code identifier), and the short-form AssemblyInfo.cs mention and the TaskMaster.runsettings mention later in the same line are also unbackticked — round 10 separately removed both of those, so neither is "unchanged" as this entry previously stated; that prior wording was stale and is corrected here. + +W4. `plan.2026-09-02T08-59.md` line 39 (D1) — re-read after editing. TaskMaster/AppGlobals/StoreRehookCoordinator.cs is now unbackticked; the sentence's `` `WaitAsync` `` and `` `Func` `` backticks (both code identifiers) are unchanged. + +W5. `plan.2026-09-02T08-59.md` line 41 (D3) — re-read after editing. Both occurrences each of TaskMaster/TaskMaster.csproj and TaskMaster/packages.config are now unbackticked (four conversions in one sentence); the sentence's `` ` _delay;` ``, `` `Func? delay = null` ``, `` `await NonBlockingDelay.WaitAsync(TimeSpan.FromMilliseconds(100));` ``, `` `` ``) are unchanged. + +W8. `plan.2026-09-02T08-59.md` citation-list item 11 (line 824) — re-read after editing.

An explicit overload pair is used rather than an optional TimeProvider? parameter because WaitAsync is consumed as a method group at StoreRehookCoordinator.cs line 102; C# ignores a candidate method whose optional parameter has no corresponding delegate parameter, which would produce CS0123 at that call site. The 1-arg overload therefore stays the unique 1-parameter candidate. Timer disposal and completion semantics are unchanged, and TaskCreationOptions.RunContinuationsAsynchronously is retained. The narrowly scoped #nullable enable/restore annotations pair is carried over for the new ITimer? local. TaskMaster.Test gains Microsoft.Bcl.TimeProvider 10.0.11 and Microsoft.Extensions.TimeProvider.Testing 10.9.0 in both its .csproj and its packages.config, mirroring the existing UtilitiesCS.Test entries. app.config is unchanged: the Microsoft.Bcl.TimeProvider binding redirect is already present and none is needed for the testing package.

From 4b72cc7bae1cd9c94a7b667e20cf98663aac520b Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Wed, 2 Sep 2026 23:26:22 -0400 Subject: [PATCH 05/10] test(729): remove live Form types from SVGControl.Test and install structural guard Delete the six compiled-but-unreferenced Form1/Form2 sources and their csproj / entries, and add the ported NoLiveFormInTestAssemblyTests structural guard so the condition cannot return. Red-before and green-after runs of the guard are recorded under the feature evidence folder; the red-before failure text names both SVGControl.Test.Form1 and SVGControl.Test.Form2.

From 79088aabbe41e33dcf9e56647705ecbe2b6ad001 Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Wed, 2 Sep 2026 23:32:24 -0400 Subject: [PATCH 07/10] test(729): serialize the two Console.Out-capturing UtilitiesCS.Test classes Add a class-level [DoNotParallelize] attribute plus a hazard comment to DASLFilterParserTests and StackGeek_Tests, the only two compiled UtilitiesCS.Test classes that capture, restore, and assert on process-global Console.Out without the attribute. The comments cite UtilitiesCS.Test/Properties/AssemblyInfo.cs lines 18-21 as the live source of the class-level parallel scope, because the CI vstest invocation passes no /Settings: argument. Also delete the orphan duplicate DASLFilterParser_Tests.cs, which is absent from the csproj and would reintroduce the hazard if added to it. The change is additive only: no test body, assertion, or test-method name is altered. A deterministic red run is not producible for this race; a fail-before exception dossier records why and cites the two in-repo precedent classes.

A sibling class captures `Console.Out` while this class's `StringWriter` is installed, and + reinstalls that `StringWriter` after this class's `using` block has disposed it.

No deterministic red run is therefore producible, and none is claimed. + +The remedy is also not observable as a test outcome: `[DoNotParallelize]` moves each class into +MSTest's serial partition, which removes the concurrency that the race needs. Its effect is the +absence of a nondeterministic failure, which no single run can demonstrate. + +## Alternative proof — two in-repo precedent classes + +The hazard is not hypothetical.

From 0fdadefeabf264be3cfbf03aa7f980ec19719c09 Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Wed, 2 Sep 2026 23:59:09 -0400 Subject: [PATCH 08/10] chore(729): record Phase 6 QA gates and absorb the scope-locked formatter rewrite Commits the Phase 6 final-QA evidence set together with the one real rewrite the scope-locked CSharpier pass applied to a file that an earlier phase commit had already committed. - csharpier format (scope-locked to the seven plan-owned formattable paths), csharpier check, msbuild analyzers, msbuild nullable, and the full MSTest coverage run all exit 0 in a single final pass. - The formatter reached a fixpoint on its second pass with RewrittenFileCount 0. Its one content rewrite wrapped a .BeFalse(...) call in TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs; formatter output wins. - Coverage delta: TaskMaster/AppGlobals/NonBlockingDelay.cs is at 20/20 covered lines, up from 17/17, with all three added lines covered. Repository-wide line-rate and branch-rate movement is within the stated 0.0005 tolerance band, and the only file showing a covered-line decrease is outside this change's write set. - All six plan-owned .cs files are at or below the 500-line limit.

The file grew +from 17 to 20 measured lines because the 2-arg overload was added, and all three added lines are +covered. + +### Clause 3 — write-set attribution gate: PASS + +`NegativeMovementFiles:` contains exactly one entry, +`UtilitiesCS/Interfaces/IWinForm/PropertyStore.cs`. That path does not appear anywhere in this +plan's Complete file-write inventory: it is not the single production source entry, it is not one +of the three modified test sources, it is not one of the two created test sources, it is not one +of the four modified project files or package manifests, it is not one of the seventeen deleted +files, and it is not feature documentation or evidence.

From e6c488bf46cec739bddcf4ee07ba070c45b85668 Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Thu, 3 Sep 2026 00:12:12 -0400 Subject: [PATCH 09/10] docs(729): record Phase 7 scope-boundary evidence, delivery record, and AC check-off MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commits the remaining feature documentation and evidence for issue #729, including the Phase 0 baseline set, the Phase 7 scope-boundary gates, the delivery record, and the acceptance-criteria check-off state. - Scope boundaries verified against the merge base: the Finding 3 production parser is untouched and gains no TextWriter seam; exactly one non-test production source file changed; no QuickFiler path changed; and no push-down-owned path is committed on this branch. - The changed-file inventory matches the plan's write inventory element for element, with seventeen deletions and six explained deltas. - spec.md now enumerates the four verified reasons no test-only fix exists for Finding 4, which is out of scope and carried by issue #743. - The research artifact carries an appended correction: its §1.4 zero-due-time premise was falsified by two reproductions of the executed run, which observed FakeTimeProvider invoking a zero-due-time timer during CreateTimer. - The feature folder is swept clean of host identifiers: residual match count 0 over 53 files, with no file rewritten and both Cobertura artifacts well-formed. - All 21 acceptance criteria are verified and checked off in spec.md.

Every toolchain command this plan runs (`dotnet tool run csharpier +check .`, the two `msbuild TaskMaster.sln /t:Rebuild` invocations, and the coverage run) is +character-for-character unchanged, so no plan task, decision record, or acceptance condition +is invalidated by the reconciliation. + +Output Summary: The merge base of `origin/main` and `HEAD` is the 40-character hexadecimal SHA +recorded in `BaseRef:` above. `origin/main` was merged into this branch twice: once during +Phase 0 (merge commit `3c1fb73c`) and once at resume after sibling item #564 landed on `main`. +Every later `$base`-anchored git acceptance in this plan re-derives `$base` per task, per D11, +and asserts equality against the `BaseRef:` value recorded here before proceeding. diff --git a/docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/baseline/citation-verification.2026-09-02T10-30.md b/docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/baseline/citation-verification.2026-09-02T10-30.md new file mode 100644 index 000000000..5cd2dfdee --- /dev/null +++ b/docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/baseline/citation-verification.2026-09-02T10-30.md @@ -0,0 +1,134 @@ +# Citation verification (P0-T13) + +Timestamp: 2026-09-03T01-30 + +Command: read each cited line span directly from the current working tree with a line-numbered +extraction and compare the observed text against the anchor the plan asserts. + +EXIT_CODE: 0 + +Twelve anchors were re-verified.

A guard would add a branch outcome that no in-scope test can reach without a fourth test method that the spec's Test Strategy does not authorize, and an unreached branch outcome lowers branch coverage on a changed production file. This is a deliberate minimal-change decision. - **D3 — No production project-file edit for `TimeProvider`.** Re-derived against the current tree: TaskMaster/TaskMaster.csproj already carries `/ outside any plan task, and P0-T15 records that some such paths are already dirty before Phase 1 begins. The `git diff $base HEAD` half of P7-T4 stays an unconditional empty-output assertion because no plan task commits any such path. P7-T2, P7-T4, and P8-T22 therefore evaluate cleanliness against the P0-T15 recorded set plus the .claude/agent-memory/ allowance rather than against the empty set. -- **D11 — `$base` is re-derived per task.** The shell resets between tasks, so every task whose command text contains `$base` begins its payload with `$base = (git merge-base origin/main HEAD).Trim()` and then asserts that `$base` equals the `BaseRef:` value recorded by P0-T14. A task that finds a different value stops and reports rather than proceeding on a drifted base. +- **D11 — `$base` is re-derived per task, against the currently recorded anchor.** The shell resets between tasks, so every task whose command text contains `$base` begins its payload with `$base = (git merge-base origin/main HEAD).Trim()` and then asserts that `$base` equals the `BaseRef:` value recorded by P0-T14. The authoritative anchor is `8be5a6aac3b5a82c86241fbbf989fd9118602c56`, which is the value that artifact now records. A task that finds a different value stops and reports rather than proceeding on a drifted base. The merge base is not immutable for the duration of execution, and re-anchoring is the correct response to a mid-run reconciliation rather than a violation of this decision: while this item was stopped, sibling parallel item #564 merged to `main`, and the orchestrator reconciled this branch by merging `origin/main` at resume, which moved `git merge-base origin/main HEAD` from a now-superseded value to the value named above. The P0-T14 artifact carries a Re-anchor record documenting that move and its rationale. Anchoring to the superseded value instead would bill sibling item #564's twenty files to this item's footprint, because those files are reachable from `HEAD` through the reconciliation merge and every `$base`-anchored diff acceptance in this plan would therefore enumerate them as this item's own changes. No task's command text changes as a result: each task already re-derives `$base` at run time, which is what makes the re-anchor self-applying. - **D12 — Test-count assertions are numeric, not whitespace-matched.** `vstest.console.exe` summary formatting varies between versions, so no acceptance in this plan matches the console line's internal spacing. Each test task records the passed count and the failed count as integers in its evidence artifact and its acceptance compares those integers. - **D13 — Cobertura artifacts carry a declared processing state.** `scripts/vscode/Invoke-MSTestWithCoverage.ps1` calls `ConvertTo-KoverageCoberturaXml` at line 340, asserts the 80% line threshold at line 341, and writes the post-processed XML at line 343. Any throw before line 343 — from the collection call at line 326 or from the threshold assertion at line 341 — leaves the raw dotnet-coverage output on disk. The processed and raw forms are not on the same denominator, because the conversion removes non-allowlisted packages and then rewrites the root `line-rate`, `branch-rate`, `lines-covered`, `lines-valid`, `branches-covered`, and `branches-valid` attributes (`Invoke-MSTestWithCoverage.Helpers.ps1` lines 417-447). Both full-suite tasks therefore record `CoberturaProcessingState:` and P6-T6 refuses to compare across a mismatch without converting the raw side first. - **D14 — One authorized re-run for #743-tracked QuickFiler.Test failures, and nothing wider.** `Invoke-DotnetCoverageCollection` throws on any non-zero coverage exit code (`Invoke-MSTestWithCoverage.ps1` lines 235-237), so a single load-sensitive QuickFiler.Test pump timeout aborts the whole gate. `spec.md` line 87 records that failure mode as out of scope and carried by issue #743, and this plan modifies no QuickFiler/ file. The full-suite tasks therefore authorize exactly one mechanical re-run when every failing node is in QuickFiler.Test, require the failing node identifiers to be enumerated, and treat a failure in any other assembly as a genuine gate failure. - **D15 — The Phase 6 formatter pass is staged by P6-T9.** The scope-locked `csharpier format` pass in P6-T1 runs after all five phase commits, so any rewrite it applies to the seven plan-owned formattable source paths is left unstaged by every earlier task. P6-T9 therefore stages those seven paths in addition to the Phase 6 evidence, and P8-T22 amends its own commit to absorb its own check-off line. +- **D16 — The guards' `because` argument deliberately differs from the model source.** Blocks E and F are ported from QuickFiler.Test/NoLiveFormInTestAssemblyTests.cs, and their `BeEmpty` `because` argument is the one place where the port is not a copy: it now enumerates every offending type by concatenating `string.Join(", ", formDerivedTypeNames)`, because FluentAssertions 8.10.0 renders a non-empty-collection failure as one representative item and would otherwise never print the second type that P3-T4 and spec.md AC11 both require by name. Block F is changed identically even though its guard is green from birth and never renders the message, so that the two new files stay identical apart from the namespace and so that a future live violation in UtilitiesCS.Test reports every offending type rather than one. spec.md line 264 AC9 and the spec.md line 76 Finding 2 port description scope the "carried over unchanged" requirement to the `GetLoadableTypes` `ReflectionTypeLoadException` fallback specifically, which this change does not touch, so the deviation is compatible with both. --- @@ -101,9 +102,9 @@ Files deleted (17): Feature documentation and evidence written: - `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/plan.2026-09-02T08-59.md` -- `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` (AC checkbox state, plus the one Block L insertion under the Finding 4 out-of-scope bullet required by AC16; no other spec content changes) -- `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/issue.md` — authored before this plan and untracked until P8-T22's directory-level `git add` commits it; this plan does not edit its content -- `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/research/research-729.2026-09-02T09-30.md` — authored before this plan and untracked until P8-T22's directory-level `git add` commits it; this plan does not edit its content except for any host-identifier substitution P7-T8 applies +- `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` (the revision-round-14 corrections to the Assumptions bullet, the Test Strategy Finding 1 paragraph, the Risks zero-delay entry, and AC5, applied before execution resumed and uncommitted until P8-T22; the acceptance-criteria checkbox state written by Phase 8; and the one Block L insertion under the Finding 4 out-of-scope bullet required by AC16, written by P7-T7.

Acceptance: the artifact exists and contains the literal field names `SearchScope:`, `SearchPatterns:`, `SearchResult:`, and `WhyFailingRunImpossible:`. -- [ ] [P2-T6] Stage and commit with `git add TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs` plus the Phase 2 evidence paths, using a commit subject beginning `test(729): `.

Acceptance: `Select-String -SimpleMatch 'WaitAsync_WithNoDispatcher_CompletesAfterInterval' -Path 'TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs'` returns exactly one match, the same for `WaitAsync_ZeroDelay_CompletesWithoutPump` and for `WaitAsync_SingleArgumentOverload_CompletesOnSystemTimeProvider`, and `Select-String -SimpleMatch '[Timeout(5000)]' -Path 'TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs'` returns exactly three matches. +- [x] [P2-T3] Build the `TaskMaster.Test` project with the Block K prelude and `& $msbuild TaskMaster.Test\TaskMaster.Test.csproj /t:Rebuild /m /p:Configuration=Debug /p:Platform=AnyCPU`, and record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/build-taskmaster-test.2026-09-02T10-30.md`. Acceptance: `EXIT_CODE: 0` and `Test-Path TaskMaster.Test\bin\Debug\TaskMaster.Test.dll` returns `True`, pasted into `Output Summary:`. +- [x] [P2-T4] Run the three rewritten tests with the Block K prelude and `& $vstest TaskMaster.Test\bin\Debug\TaskMaster.Test.dll /Settings:scripts\vscode\TaskMaster.cli.runsettings /InIsolation /TestCaseFilter:"FullyQualifiedName~NonBlockingDelayTests"`, and record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/regression-testing/nonblockingdelay-tests.2026-09-02T10-30.md`. Before running the command, preserve the round-14 failing-run record that this path currently holds. If `Test-Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/regression-testing/nonblockingdelay-tests.2026-09-02T10-30.md'` returns `True`, run `Rename-Item -Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/regression-testing/nonblockingdelay-tests.2026-09-02T10-30.md' -NewName 'nonblockingdelay-zero-delay-observation.2026-09-02T10-30.md'`. If it returns `False` and `Test-Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/regression-testing/nonblockingdelay-zero-delay-observation.2026-09-02T10-30.md'` returns `True`, the preservation has already been performed by an earlier attempt at this task; skip the rename and proceed. If both return `True`, an earlier attempt already performed the preservation and then wrote a fresh artifact at the source path; skip the rename and proceed, leaving the existing preserved file untouched, because renaming onto an existing destination would fail and must not be retried in a way that could overwrite the preserved record. If both return `False`, stop and report, because the observation record is missing and four committed citations depend on it. The preserved file is the executed-run record of the zero-due-time behaviour and is the authority Block B's zero-delay assertion, `spec.md`'s Assumptions bullet, its Test Strategy Finding 1 paragraph, and its Risks zero-delay entry all rest on. It must not remain at the path this task's own passing run writes, because it records `EXIT_CODE: 1` for a superseded Block B and the evidence collector reads a duplicated `EXIT_CODE:` field first-occurrence-wins, which would normalize this task's result to a failure. In the renamed file only, and only on the pass that performs the rename, change its first line to `# FakeTimeProvider zero-due-time observation (superseded P2-T4 run, revision round 14)` and insert the single line `ExpectedExitCode: 1` immediately below the `EXIT_CODE: 1` schema field near the head of the file. That text occurs twice in the preserved artifact: once as the schema field, and once inside the fenced determinism-confirmation block lower down. Insert below the schema field only. Placing the new line inside the fenced block would leave the expectation unrecognized, the default expectation of `0` would apply, and the preserved artifact would render as a failed gate. Change nothing else in it; the body is a point-in-time record. No retry branch is authorized for this task: any failure is a genuine gate failure that must be escalated for a plan revision rather than repaired by a mechanical edit to the test source. Acceptance: `EXIT_CODE: 0`, and the artifact records `PassedCount: 3` and `FailedCount: 0` with the three test-method names listed, and `Test-Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/regression-testing/nonblockingdelay-zero-delay-observation.2026-09-02T10-30.md'` returns `True`. +- [x] [P2-T5] Write `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/other/no-fail-before-rationale.2026-09-02T10-30.md` recording, as an auditable negative claim, that no fail-before run is claimed for Finding 1 or for the `UtilitiesCS.Test` guard, with `SearchScope:` naming `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/regression-testing/`, `SearchPatterns:` naming `fail-before-exception.*.md`, `SearchResult:` naming what was found, and a `WhyFailingRunImpossible:` section stating (a) for Finding 1, that the replacement tests reference the 2-arg overload and therefore cannot compile against the pre-change production file, so a red-before state is a compile error rather than a test failure, and (b) for `UtilitiesCS.Test`, that the guard is green from birth because no `Form`-derived type has ever been compiled into that assembly.

It was written by an earlier execution attempt, no task in this plan authorizes it, the `Complete file-write inventory` section does not list it, and the comment-stripped `Stopwatch` reading of P2-T1 it records is superseded because Block B no longer contains that literal in any form.

If that command instead reports the path as tracked, stop and report rather than deleting it, because a tracked state would mean some commit on this branch had already recorded this artifact, which no task in this plan authorizes; P7-T5's inventory admits exactly seventeen deletion entries and all seventeen are drawn from Phases 3 through 5.

Acceptance: `git status --porcelain -- UtilitiesCS.Test` returns empty output. ### Phase 6 — Final QA loop and coverage verification -- [ ] [P6-T1] Capture the SHA-256 of each of the seven plan-owned formattable files with `Get-FileHash -Algorithm SHA256`, run the scope-locked mutating format pass `dotnet tool run csharpier format 'TaskMaster/AppGlobals/NonBlockingDelay.cs' 'TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs' 'TaskMaster.Test/packages.config' 'UtilitiesCS.Test/NoLiveFormInTestAssemblyTests.cs' 'UtilitiesCS.Test/OutlookObjects/Filter DASL/DASLFilterParserTests.cs' 'UtilitiesCS.Test/ReusableTypeClasses/StackGeek_Tests.cs' 'SVGControl.Test/NoLiveFormInTestAssemblyTests.cs'`, capture the seven hashes again, and record all fourteen hashes plus the derived rewritten-file count in `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/csharpier-format.2026-09-02T10-30.md`. The console line `Formatted N files` is a processed-file count and must NOT be used as the rewritten-file count. A repo-wide `dotnet tool run csharpier format .` is prohibited by D4. Acceptance: `EXIT_CODE: 0` and the artifact records fourteen hash values and a `RewrittenFileCount:` integer. -- [ ] [P6-T2] Run the read-only gate `dotnet tool run csharpier check .` and record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/csharpier-check.2026-09-02T10-30.md`. Authorized mechanical branch: if the reported set contains `TaskMaster.Test/packages.config` (which CSharpier processes by filename and which a per-file invocation may skip), run `dotnet tool run csharpier format TaskMaster.Test` in directory form, re-run this check, and record both runs in the artifact. That directory-form invocation is broader than the D4 scope lock, so immediately after it run `git status --porcelain -- TaskMaster.Test` and paste the result into the artifact; every path it reports must already be one of the seven plan-owned formattable paths, and any other path it reports must be reverted to its committed state by running `git checkout HEAD --` applied to that path, with the restoration recorded, before this task is checked off. Acceptance: either `EXIT_CODE: 0`, or the final reported unformatted set is a subset of the `Baseline unformatted set:` recorded by P0-T8 after removing the seventeen paths deleted by Phases 3-5, and contains none of the seven plan-owned formattable paths and none of UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs; the artifact states which of the two outcomes held, lists the reported set verbatim, and lists the subset derivation it performed. -- [ ] [P6-T3] Run `& $msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:EnableNETAnalyzers=true /p:EnforceCodeStyleInBuild=true` using the Block K prelude and record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/msbuild-analyzers.2026-09-02T10-30.md`. Acceptance: `EXIT_CODE: 0` and the artifact's `Output Summary:` states the diagnostic count is no higher than the count recorded by P0-T9. -- [ ] [P6-T4] Run `& $msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:TreatWarningsAsErrors=true` using the Block K prelude and record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/msbuild-nullable.2026-09-02T10-30.md`. Do not add `/p:Nullable=enable`; do not substitute `/t:Build`. Acceptance: `EXIT_CODE: 0` and the artifact's `Output Summary:` states the log contains zero occurrences of `CS8632`. -- [ ] [P6-T5] Run `pwsh -NoProfile -File .\scripts\vscode\Invoke-MSTestWithCoverage.ps1 -SearchRoot . -Configuration Debug -CoverageOutput 'docs\features\active\2026-09-02-test-determinism-and-hygiene-debt-729\evidence\qa-gates\coverage-final.cobertura.xml'` and record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/mstest-coverage.2026-09-02T10-30.md`, pasting into `Output Summary:` the `Discovered N test assemblies.` line, the vstest total/passed/failed counts, and the `line-rate` and `branch-rate` attribute values read from the `` root element of `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/coverage-final.cobertura.xml`. Authorized non-zero branch: if the script exits non-zero and its error text contains the literal `is below the required 80% threshold`, record that observed exit code together with the line `ExpectedExitCode: 1` and the literal note `Threshold assertion fired; raw Cobertura was written before the assertion and the numeric rates below were read from it.` Authorized mechanical re-run branch: if the run reports failures and every failing test node is in QuickFiler.Test and is one of the pump-hosted classes tracked by issue #743, re-run this exact command once, record both runs and the full list of failing test node identifiers in the artifact, and treat the second run's counts as authoritative. If a #743-tracked failure persists after the second run, record it in the artifact and in the delivery-record task as a known out-of-scope flake. A failure in any other assembly is not covered by this branch. Record the field `CoberturaProcessingState:` with the value `processed` when the script exited 0, and the value `raw` when the script exited non-zero under either authorized branch above; the value is `raw` in those cases because `scripts/vscode/Invoke-MSTestWithCoverage.ps1` writes the post-processed XML at line 343 only after both the collection call at line 326 and the threshold assertion at line 341 have returned, so a throw at either point leaves the dotnet-coverage output on disk unrewritten. The runner writes a transient derived coverage-settings file adjacent to the Cobertura output and deletes it in a finally block. Confirm no stranded derived settings file remains before checking this task off: `Test-Path 'docs\features\active\2026-09-02-test-determinism-and-hygiene-debt-729\evidence\qa-gates\coverage-final.cobertura.xml.effective-coverage.config'` returns `False`, and `Get-ChildItem -Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates' -Filter '*.effective-coverage.config'` returns zero items; if either shows the file present, delete it and repeat the confirmation. Then, because no logger is configured for the runner's inner vstest invocation (`scripts/vscode/Invoke-MSTestWithCoverage.ps1` line 76 passes only `/Settings:`, `/InIsolation`, and `/TestCaseFilter:`) and the default console logger does not enumerate passing test nodes, obtain the two per-node outcomes from two immediately following scoped confirmation runs using the Block K prelude: `& $vstest UtilitiesCS.Test\bin\Debug\UtilitiesCS.Test.dll /Settings:scripts\vscode\TaskMaster.cli.runsettings /InIsolation /TestCaseFilter:"FullyQualifiedName~NoLiveFormInTestAssemblyTests" /Logger:"trx;LogFileName=utilitiescs-noliveform.trx" /ResultsDirectory:coverage\trx\p6t5` and `& $vstest SVGControl.Test\bin\Debug\SVGControl.Test.dll /Settings:scripts\vscode\TaskMaster.cli.runsettings /InIsolation /TestCaseFilter:"FullyQualifiedName~NoLiveFormInTestAssemblyTests" /Logger:"trx;LogFileName=svgcontrol-noliveform.trx" /ResultsDirectory:coverage\trx\p6t5`. Each TRX contains exactly one `` element; read its `outcome` attribute and pair it with the fully-qualified identifier of the assembly that produced that TRX. Transcribe into `Output Summary:` two lines of the form ` outcome="Passed"`, one per run, plus each run's exit code. Two single-assembly runs are used rather than one combined run because both assemblies declare a class named `NoLiveFormInTestAssemblyTests` with a method named `ExecutingAssembly_ContainsNoFormDerivedType`, and a TRX `` element carries only the bare method name, so a combined TRX cannot distinguish the two nodes without a `` join. Transcribe only the derived fully-qualified test-node identifier and its `outcome` value. Do not paste a raw `` element, which carries a `computerName` host identifier. `coverage/` is gitignored at `.gitignore` line 144, so both TRX files leave the tracked tree clean. This task runs three commands; the artifact's single `Command:` and `EXIT_CODE:` fields carry the `Invoke-MSTestWithCoverage.ps1` run, because that is the run the coverage gate and any `ExpectedExitCode:` apply to, and the two scoped confirmation commands with their own exit codes are recorded inside `Output Summary:`. Acceptance: the artifact records `FailedCount: 0` — or, under the #743 branch above, a `FailedCount:` whose every failing test node identifier is listed in the artifact and is in QuickFiler.Test — plus a `PassedCount:` integer greater than 0, a numeric `line-rate`, a numeric `branch-rate`, a `CoberturaProcessingState:` value of `processed` or `raw`, the two stranded-settings observations above, and both literal tokens `UtilitiesCS.Test.NoLiveFormInTestAssemblyTests.ExecutingAssembly_ContainsNoFormDerivedType` and `SVGControl.Test.NoLiveFormInTestAssemblyTests.ExecutingAssembly_ContainsNoFormDerivedType` each recorded with `outcome="Passed"`; and the artifact records, per D9, the integer discovered-assembly count matching the `Discovered N test assemblies.` line, the boolean result that zero discovered paths contain a `\worktrees\` segment below the resolved search root, and the repository-relative form of each discovered assembly path with no absolute path written. -- [ ] [P6-T6] Compare coverage against the Phase 0 baseline and record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/coverage-delta.2026-09-02T10-30.md` with the fields `BaselineLineRate:`, `PostChangeLineRate:`, `BaselineBranchRate:`, `PostChangeBranchRate:`, `BaselineCoveredLines:`, `PostChangeCoveredLines:`, `BaselineTotalLines:`, `PostChangeTotalLines:`, where the four line-count fields aggregate every `` element whose `filename` attribute ends with `NonBlockingDelay.cs`. Before reading any value, compare the `CoberturaProcessingState:` recorded by P0-T11 against the one recorded by P6-T5: both artifacts must declare the same `CoberturaProcessingState:`; if they differ, dot-source `scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1`, call `ConvertTo-KoverageCoberturaXml` with `-RepoRoot (Resolve-Path .).Path` and with `-XmlContent` set to the raw side's content read via `Get-Content -Raw -Encoding UTF8` from `docs\features\active\2026-09-02-test-determinism-and-hygiene-debt-729\evidence\baseline\coverage-baseline.cobertura.xml` when the baseline is the raw side, or from `docs\features\active\2026-09-02-test-determinism-and-hygiene-debt-729\evidence\qa-gates\coverage-final.cobertura.xml` when the post-change run is the raw side, and read the four rate fields and both `NonBlockingDelay.cs` line counts for that side from the converted string rather than from the file on disk, recording in this artifact that this conversion was performed and which side it was applied to. Comparing a raw Cobertura against a processed one is prohibited because `ConvertTo-KoverageCoberturaXml` removes non-allowlisted packages and then rewrites the root `line-rate`, `branch-rate`, `lines-covered`, `lines-valid`, `branches-covered`, and `branches-valid` attributes (`scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1` lines 417-447), so the two forms are not on the same denominator. Acceptance: the artifact records both `CoberturaProcessingState:` values and states whether a conversion was performed; `PostChangeTotalLines` is greater than 0; `PostChangeLineRate` is greater than or equal to `BaselineLineRate`, `PostChangeBranchRate` is greater than or equal to `BaselineBranchRate`, and `PostChangeCoveredLines` divided by `PostChangeTotalLines` is greater than or equal to `BaselineCoveredLines` divided by `BaselineTotalLines`; all eight values and the two comparisons are written into the artifact. `BaselineTotalLines` is already required to be greater than 0 by P0-T12, so both ratios have a non-zero denominator. -- [ ] [P6-T7] Audit file length for the six plan-owned `.cs` files after formatting and record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/file-size-audit.2026-09-02T10-30.md` with one line count per file for `TaskMaster/AppGlobals/NonBlockingDelay.cs`, `TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs`, `UtilitiesCS.Test/NoLiveFormInTestAssemblyTests.cs`, `SVGControl.Test/NoLiveFormInTestAssemblyTests.cs`, `UtilitiesCS.Test/ReusableTypeClasses/StackGeek_Tests.cs`, and `UtilitiesCS.Test/OutlookObjects/Filter DASL/DASLFilterParserTests.cs`. Acceptance: the artifact records six counts and every recorded count is less than or equal to 500. -- [ ] [P6-T8] Record the single-pass toolchain result in `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/toolchain-single-pass.2026-09-02T10-30.md`, listing the five commands from P6-T1 through P6-T5 in order with their exit codes. If P6-T1 reported a `RewrittenFileCount:` greater than 0, or if any of P6-T2 through P6-T5 did not meet its acceptance, re-execute P6-T1 through P6-T5 in order and record the final pass in this same artifact. A P6-T5 artifact recording `ExpectedExitCode: 1` with the literal threshold message and `FailedCount: 0` satisfies this task. A P6-T2 artifact whose final reported unformatted set is a subset of the `Baseline unformatted set:` recorded by P0-T8 after removing the seventeen paths deleted by Phases 3-5, and contains none of the seven plan-owned formattable paths and none of UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs, also satisfies this task. Acceptance: the artifact records a final pass in which `RewrittenFileCount:` is 0 and P6-T2 through P6-T5 each met their acceptance, counting the two allowances stated above as met. -- [ ] [P6-T9] Stage and commit all Phase 6 evidence together with any rewrite the P6-T1 scope-locked formatter pass applied to the seven plan-owned formattable source paths, which are committed by Phases 1 through 5 and are therefore not staged by any earlier task.

The console line `Formatted N files` is a processed-file count and must NOT be used as the rewritten-file count. A repo-wide `dotnet tool run csharpier format .` is prohibited by D4. Acceptance: `EXIT_CODE: 0` and the artifact records fourteen hash values and a `RewrittenFileCount:` integer. +- [x] [P6-T2] Run the read-only gate `dotnet tool run csharpier check .` and record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/csharpier-check.2026-09-02T10-30.md`. Authorized mechanical branch: if the reported set contains `TaskMaster.Test/packages.config` (which CSharpier processes by filename and which a per-file invocation may skip), run `dotnet tool run csharpier format TaskMaster.Test` in directory form, re-run this check, and record both runs in the artifact. That directory-form invocation is broader than the D4 scope lock, so immediately after it run `git status --porcelain -- TaskMaster.Test` and paste the result into the artifact; every path it reports must already be one of the seven plan-owned formattable paths, and any other path it reports must be reverted to its committed state by running `git checkout HEAD --` applied to that path, with the restoration recorded, before this task is checked off. Acceptance: either `EXIT_CODE: 0`, or the final reported unformatted set is a subset of the `Baseline unformatted set:` recorded by P0-T8 after removing the seventeen paths deleted by Phases 3-5, and contains none of the seven plan-owned formattable paths and none of UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs; the artifact states which of the two outcomes held, lists the reported set verbatim, and lists the subset derivation it performed. +- [x] [P6-T3] Run `& $msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:EnableNETAnalyzers=true /p:EnforceCodeStyleInBuild=true` using the Block K prelude and record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/msbuild-analyzers.2026-09-02T10-30.md`.

Authorized non-zero branch: if the script exits non-zero and its error text contains the literal `is below the required 80% threshold`, record that observed exit code together with the line `ExpectedExitCode: 1` and the literal note `Threshold assertion fired; raw Cobertura was written before the assertion and the numeric rates below were read from it.` Authorized mechanical re-run branch: if the run reports failures and every failing test node is in QuickFiler.Test and is one of the pump-hosted classes tracked by issue #743, re-run this exact command once, record both runs and the full list of failing test node identifiers in the artifact, and treat the second run's counts as authoritative. If a #743-tracked failure persists after the second run, record it in the artifact and in the delivery-record task as a known out-of-scope flake. A failure in any other assembly is not covered by this branch. Record the field `CoberturaProcessingState:` with the value `processed` when the script exited 0, and the value `raw` when the script exited non-zero under either authorized branch above; the value is `raw` in those cases because `scripts/vscode/Invoke-MSTestWithCoverage.ps1` writes the post-processed XML at line 343 only after both the collection call at line 326 and the threshold assertion at line 341 have returned, so a throw at either point leaves the dotnet-coverage output on disk unrewritten. The runner writes a transient derived coverage-settings file adjacent to the Cobertura output and deletes it in a finally block. Confirm no stranded derived settings file remains before checking this task off: `Test-Path 'docs\features\active\2026-09-02-test-determinism-and-hygiene-debt-729\evidence\qa-gates\coverage-final.cobertura.xml.effective-coverage.config'` returns `False`, and `Get-ChildItem -Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates' -Filter '*.effective-coverage.config'` returns zero items; if either shows the file present, delete it and repeat the confirmation. Then, because no logger is configured for the runner's inner vstest invocation (`scripts/vscode/Invoke-MSTestWithCoverage.ps1` line 76 passes only `/Settings:`, `/InIsolation`, and `/TestCaseFilter:`) and the default console logger does not enumerate passing test nodes, obtain the two per-node outcomes from two immediately following scoped confirmation runs using the Block K prelude: `& $vstest UtilitiesCS.Test\bin\Debug\UtilitiesCS.Test.dll /Settings:scripts\vscode\TaskMaster.cli.runsettings /InIsolation /TestCaseFilter:"FullyQualifiedName~NoLiveFormInTestAssemblyTests" /Logger:"trx;LogFileName=utilitiescs-noliveform.trx" /ResultsDirectory:coverage\trx\p6t5` and `& $vstest SVGControl.Test\bin\Debug\SVGControl.Test.dll /Settings:scripts\vscode\TaskMaster.cli.runsettings /InIsolation /TestCaseFilter:"FullyQualifiedName~NoLiveFormInTestAssemblyTests" /Logger:"trx;LogFileName=svgcontrol-noliveform.trx" /ResultsDirectory:coverage\trx\p6t5`. Each TRX contains exactly one `` element; read its `outcome` attribute and pair it with the fully-qualified identifier of the assembly that produced that TRX. Transcribe into `Output Summary:` two lines of the form ` outcome="Passed"`, one per run, plus each run's exit code. Two single-assembly runs are used rather than one combined run because both assemblies declare a class named `NoLiveFormInTestAssemblyTests` with a method named `ExecutingAssembly_ContainsNoFormDerivedType`, and a TRX `` element carries only the bare method name, so a combined TRX cannot distinguish the two nodes without a `` join. Transcribe only the derived fully-qualified test-node identifier and its `outcome` value. Do not paste a raw `` element, which carries a `computerName` host identifier. `coverage/` is gitignored at `.gitignore` line 144, so both TRX files leave the tracked tree clean. This task runs three commands; the artifact's single `Command:` and `EXIT_CODE:` fields carry the `Invoke-MSTestWithCoverage.ps1` run, because that is the run the coverage gate and any `ExpectedExitCode:` apply to, and the two scoped confirmation commands with their own exit codes are recorded inside `Output Summary:`. Acceptance: the artifact records `FailedCount: 0` — or, under the #743 branch above, a `FailedCount:` whose every failing test node identifier is listed in the artifact and is in QuickFiler.Test — plus a `PassedCount:` integer greater than 0, a numeric `line-rate`, a numeric `branch-rate`, a `CoberturaProcessingState:` value of `processed` or `raw`, the two stranded-settings observations above, and both literal tokens `UtilitiesCS.Test.NoLiveFormInTestAssemblyTests.ExecutingAssembly_ContainsNoFormDerivedType` and `SVGControl.Test.NoLiveFormInTestAssemblyTests.ExecutingAssembly_ContainsNoFormDerivedType` each recorded with `outcome="Passed"`; and the artifact records, per D9, the integer discovered-assembly count matching the `Discovered N test assemblies.` line, the boolean result that zero discovered paths contain a `\worktrees\` segment below the resolved search root, and the repository-relative form of each discovered assembly path with no absolute path written. +- [x] [P6-T6] Compare coverage against the Phase 0 baseline and record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/coverage-delta.2026-09-02T10-30.md` with the fields `BaselineLineRate:`, `PostChangeLineRate:`, `BaselineBranchRate:`, `PostChangeBranchRate:`, `BaselineCoveredLines:`, `PostChangeCoveredLines:`, `BaselineTotalLines:`, `PostChangeTotalLines:`, where the four line-count fields aggregate every `` element whose `filename` attribute ends with `NonBlockingDelay.cs`. Before reading any value, compare the `CoberturaProcessingState:` recorded by P0-T11 against the one recorded by P6-T5: both artifacts must declare the same `CoberturaProcessingState:`; if they differ, dot-source `scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1`, call `ConvertTo-KoverageCoberturaXml` with `-RepoRoot (Resolve-Path .).Path` and with `-XmlContent` set to the raw side's content read via `Get-Content -Raw -Encoding UTF8` from `docs\features\active\2026-09-02-test-determinism-and-hygiene-debt-729\evidence\baseline\coverage-baseline.cobertura.xml` when the baseline is the raw side, or from `docs\features\active\2026-09-02-test-determinism-and-hygiene-debt-729\evidence\qa-gates\coverage-final.cobertura.xml` when the post-change run is the raw side, and read the four rate fields and both `NonBlockingDelay.cs` line counts for that side from the converted string rather than from the file on disk, recording in this artifact that this conversion was performed and which side it was applied to. Comparing a raw Cobertura against a processed one is prohibited because `ConvertTo-KoverageCoberturaXml` removes non-allowlisted packages and then rewrites the root `line-rate`, `branch-rate`, `lines-covered`, `lines-valid`, `branches-covered`, and `branches-valid` attributes (`scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1` lines 417-447), so the two forms are not on the same denominator. Additionally record these fields, each read from the same two documents: `BaselineLinesValid:` and `PostChangeLinesValid:` from the `lines-valid` attribute of each document's `` root, their difference as `LinesValidDelta:`, and `LinesValidChangedFiles:` enumerating every `filename` whose aggregated instrumented-line count differs between the two documents with both counts shown; `NegativeMovementFiles:` enumerating every `filename` whose aggregated covered-line count is lower in the post-change document than in the baseline document, each with its baseline and post-change covered-over-total figures; `LineRateDelta:` as `PostChangeLineRate` minus `BaselineLineRate` and `BranchRateDelta:` as `PostChangeBranchRate` minus `BaselineBranchRate`, each written to at least six decimal places; and `CounterfactualLineRate:`, which is the post-change `lines-covered` adjusted to remove the net covered-line movement contributed by files that are not in this plan's Complete file-write inventory, divided by the post-change `lines-valid`, together with `CounterfactualLineRateDelta:` against `BaselineLineRate`. The counterfactual and its delta are recorded whether or not they are favourable, because they are what distinguishes a coverage reduction caused by this change from a coverage reduction caused by movement in files this change never writes. The repository-wide comparison below uses a stated tolerance band of `0.0005` on each rate rather than an exact greater-than-or-equal-to comparison. `0.0005` is 0.05 percentage points. It was chosen as roughly three times the 10-line covered-line churn observed in untouched files, measured against a post-change denominator of `64578` lines. An exact comparison is not used because `lines-covered` is not deterministic at this resolution in this repository, while `lines-valid` is; clause 1 therefore places the hard exact gate on the deterministic quantity and clause 4 places a bounded gate on the non-deterministic one. Acceptance: the artifact records both `CoberturaProcessingState:` values and states whether a conversion was performed, records all eight of `BaselineLineRate:`, `PostChangeLineRate:`, `BaselineBranchRate:`, `PostChangeBranchRate:`, `BaselineCoveredLines:`, `PostChangeCoveredLines:`, `BaselineTotalLines:`, and `PostChangeTotalLines:`, and satisfies all four of the following clauses, each of which is recorded in the artifact with the values it was decided on. (1) Deterministic denominator gate: `PostChangeTotalLines` is greater than 0, `LinesValidDelta:` equals the sum of the per-file differences listed in `LinesValidChangedFiles:`, and every `filename` listed in `LinesValidChangedFiles:` appears in this plan's Complete file-write inventory. (2) Changed-file no-regression gate: `PostChangeCoveredLines` divided by `PostChangeTotalLines` is greater than or equal to `BaselineCoveredLines` divided by `BaselineTotalLines`. `BaselineTotalLines` is already required to be greater than 0 by P0-T12, so both ratios have a non-zero denominator. (3) Write-set attribution gate: no `filename` listed in `NegativeMovementFiles:` appears in this plan's Complete file-write inventory. (4) Repository-wide tolerance gate: `BaselineLineRate` minus `PostChangeLineRate` is no greater than `0.0005`, and `BaselineBranchRate` minus `PostChangeBranchRate` is no greater than `0.0005`. This acceptance remains able to fail: clause 1 fails on a `lines-valid` change that no file in the write inventory explains, because `lines-valid` is deterministic and an unexplained change in it is real signal; clause 2 fails on a covered-over-total regression for `TaskMaster/AppGlobals/NonBlockingDelay.cs`; clause 3 fails when any file this plan writes shows a covered-line decrease, which is a real regression and is not tolerated at any magnitude; and clause 4 fails on a repository-wide line-rate or branch-rate drop larger than the stated `0.0005` band. Every value this acceptance reads is present in the two Cobertura documents already on disk, so no additional test run is authorized or required by this task; selecting a favourable run from a set of runs is prohibited, because it would make this acceptance unfalsifiable. +- [x] [P6-T7] Audit file length for the six plan-owned `.cs` files after formatting and record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/file-size-audit.2026-09-02T10-30.md` with one line count per file for `TaskMaster/AppGlobals/NonBlockingDelay.cs`, `TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs`, `UtilitiesCS.Test/NoLiveFormInTestAssemblyTests.cs`, `SVGControl.Test/NoLiveFormInTestAssemblyTests.cs`, `UtilitiesCS.Test/ReusableTypeClasses/StackGeek_Tests.cs`, and `UtilitiesCS.Test/OutlookObjects/Filter DASL/DASLFilterParserTests.cs`.

If P6-T1 reported a `RewrittenFileCount:` greater than 0, or if any of P6-T2 through P6-T5 did not meet its acceptance, re-execute P6-T1 through P6-T5 in order and record the final pass in this same artifact. A P6-T5 artifact recording `ExpectedExitCode: 1` with the literal threshold message and `FailedCount: 0` satisfies this task. A P6-T2 artifact whose final reported unformatted set is a subset of the `Baseline unformatted set:` recorded by P0-T8 after removing the seventeen paths deleted by Phases 3-5, and contains none of the seven plan-owned formattable paths and none of UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs, also satisfies this task. Acceptance: the artifact records a final pass in which `RewrittenFileCount:` is 0 and P6-T2 through P6-T5 each met their acceptance, counting the two allowances stated above as met. +- [x] [P6-T9] Stage and commit all Phase 6 evidence together with any rewrite the P6-T1 scope-locked formatter pass applied to the seven plan-owned formattable source paths, which are committed by Phases 1 through 5 and are therefore not staged by any earlier task.

Run `git diff --name-status $base HEAD` and `git status --porcelain`, and record the union of both outputs in `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/scope-boundary-ac18.2026-09-02T10-30.md`, classifying every path into exactly one of four buckets: production source; test project asset; feature documentation and evidence, which for this purpose includes the follow-up promotion record `docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md` that P8-T22 commits as deliberate output of this work; or agent-memory scratch, pre-existing or newly written by delegated agents during this plan's execution. The fourth bucket exists because .claude/agent-memory/ is a tracked directory whose contents are written by the persistent-memory system of delegated agents rather than by any task in this plan, and because P0-T15 records that some such paths are already dirty before Phase 1 begins. A path may be placed in the fourth bucket only if it is under .claude/agent-memory/ or is listed in the P0-T15 `PreExistingPaths:` set; `docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md` is excluded from the fourth bucket and belongs in the third even though P0-T15 lists it. For the same reason, every path under `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729` belongs in the third bucket even though P0-T15 lists the untracked feature folder: the P0-T15 clause admits a path to the fourth bucket, it does not compel one, and the fourth bucket's subject is agent-memory scratch. Acceptance: exactly one path is classified as production source and it is `TaskMaster/AppGlobals/NonBlockingDelay.cs`; every other path is assigned to one of the remaining three buckets and each fourth-bucket path names which of the two allowances covers it. -- [ ] [P7-T3] Verify no QuickFiler/ path changed.

Acceptance: `git diff --name-only $base HEAD -- .claude .codex .agents config/blast-radius.json config/orchestration-routing.json` returns empty output, and every path reported by `git status --porcelain -- .claude .codex .agents config/blast-radius.json config/orchestration-routing.json` is either listed in the P0-T15 `PreExistingPaths:` set or is under .claude/agent-memory/, which holds per-agent scratch memory rather than repository policy or configuration content; the artifact enumerates each such path and states which of the two allowances covers it. -- [ ] [P7-T5] Write the changed-file inventory `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/other/changed-file-inventory.2026-09-02T10-30.md` from `git diff --name-status $base HEAD` plus `git status --porcelain`, and compare it line by line against the "Complete file-write inventory" section of this plan. Four differences are known in advance and must be named explicitly in `Deltas:` rather than left unexplained: the `spec.md` Block L insertion authored by P7-T7 and the Phase 8 acceptance-criteria checkbox edits, both of which occur after this task and therefore cannot appear in its diff; and `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/issue.md` together with `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/research/research-729.2026-09-02T09-30.md`, which are authored before this plan, are still untracked at this point, and are committed by P8-T22's directory-level `git add` rather than by any earlier phase commit. Acceptance: the artifact records a `Deltas:` section that is either empty or explains every difference, and that names those two pending `spec.md` changes when the diff does not yet show them and those two untracked feature-documentation paths; the inventory contains exactly seventeen `D` entries. -- [ ] [P7-T6] Write the delivery record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/other/delivery-record.2026-09-02T10-30.md` stating (a) that `UtilitiesCS.Test/NoLiveFormInTestAssemblyTests.cs` is green from birth and is regression prevention rather than a fail-before/pass-after regression test, so no reviewer should expect a red run for it; (b) that `SVGControl.Test/NoLiveFormInTestAssemblyTests.cs` is the genuine red-before/green-after regression test, with the two evidence paths from P3-T4 and P3-T8; (c) the five final toolchain commands with their exit codes from Phase 6; (d) that Finding 4 is out of scope and carried by issue #743; and (e) a section headed `Known out-of-scope flakes:` that either states `None observed` or lists every failing QuickFiler.Test test node identifier recorded by the P6-T5 #743 re-run branch.

The Finding 4 bullet is the single line beginning `- **Finding 4 — pump-hosted` in the `### Out of scope / non-goals` section. AC16 requires the four verified reasons to be recorded in the spec itself; today that bullet cites `four independent reasons, §4.2` without enumerating them, so this insertion is what makes AC16 true. Change nothing else in `spec.md` in this task. Acceptance: `Select-String -SimpleMatch 'Finding 4 — reasons no test-only fix exists:' -Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md'` returns exactly one match; `Select-String -SimpleMatch 'The production code reads the context off the control, not from an injected seam.' -Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md'` returns exactly one match, and the same holds for each of the other three Block L reason sentences; before the insertion, record `(Get-Content 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md').Count`; after the insertion, the count has increased by exactly 5, which is the number of lines in Block L (its heading line plus its four numbered lines), and `Select-String -SimpleMatch '- **Finding 4 — pump-hosted' -Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md'` still returns exactly one match, and `Select-String -SimpleMatch 'four independent reasons, §4.2' -Path 'docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md'` still returns exactly one match. A ref-anchored diff is deliberately not used here: `spec.md` is untracked until P8-T22, so an anchored diff reports nothing about it and could not fail. Record both line counts and all six search results in `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/other/spec-block-l-insertion.2026-09-02T10-30.md`. -- [ ] [P7-T8] Sweep the feature folder for host identifiers before it is committed. Run a case-insensitive search over every file under `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729` for four things. The first three are fixed-string searches: the account name, derived as `Split-Path -Leaf $env:USERPROFILE`; the machine name, read from `$env:COMPUTERNAME`; and the absolute workspace-root prefix, derived at run time as `(Resolve-Path .).Path`. The fourth is a pattern search rather than a fixed-string search and serves as a residual detector only: a single ASCII letter immediately followed by the two-character drive-root sequence, that sequence constructed at run time as `([string][char]58 + [string][char]92)` so that neither this plan nor this task's own artifact contains the literal. The letter-anchored form is required because the bare two-character sequence occurs three times inside the swept file set in non-host-path contexts — twice in this plan file, where it is preceded by a straight quote and by a backtick, and once in the research artifact inside a regular-expression literal, where it is preceded by an asterisk. Rewriting any of the three would corrupt a recorded acceptance command or a research citation, and leaving them would make the acceptance below unreachable. The letter-anchored form matches none of the three and still matches every genuine absolute path. Replace every workspace-root-prefix hit with `` in its entirety — the whole absolute prefix, never only its drive-root characters, because substituting two characters inside an absolute path drives the residual count to zero while leaving the remainder of that path disclosed — and replace every account-name hit with `` and every machine-name hit with ``, using the XML-escaped forms in any `.xml`, `.cobertura.xml`, `.trx`, or `.coveragexml` artifact, because those placeholders contain angle brackets that would otherwise make the document ill-formed, and re-parse every rewritten XML-family file with `[xml](Get-Content -Raw -Encoding UTF8 $path)` to confirm it is still well-formed. After those three substitutions have been applied, replace every remaining letter-anchored absolute path — the whole path token, from its drive letter to the end of the path — with ``, using the XML-escaped form in any XML-family artifact and re-parsing it afterwards on the same terms. This fourth substitution is required because a raw, unprocessed Cobertura artifact carries third-party build-machine source paths that lie outside the workspace root and are therefore untouched by the workspace-root-prefix substitution, while still being matched by the letter-anchored residual detector: the raw dotnet-coverage output for this solution embeds `Mono.Reflection` source paths rooted at a drive-level `sources` directory. Three raw Cobertura artifacts already committed under `docs/features/active/` in this repository exhibit exactly that — `docs/features/active/2026-08-07-efcviewer-missing-lineage-and-segment-navigation-439/evidence/qa-gates/issue-439-final.cobertura.xml`, `docs/features/active/2026-08-25-quickfiler-high-confidence-partial-screen-backfill-608/evidence/qa-gates/r1-csharp-coverage.2026-08-25T12-33.cobertura.xml`, and `docs/features/active/2026-08-25-quickfiler-high-confidence-partial-screen-backfill-608/evidence/baseline/r3-csharp-coverage.2026-08-25T13-32.cobertura.xml` — each carrying 2,114 lines that the letter-anchored detector matches, of which 15 lines per artifact are the drive-level `sources` third-party paths that lie outside any workspace root and that the workspace-root-prefix substitution therefore cannot reach. A processed Cobertura carries no such path, because `scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1` lines 417-424 remove every non-allowlisted `` and rewrite each retained `class/@filename` to a repository-relative path, so this fourth substitution is a no-op there; every other `*.cobertura.xml` committed under `docs/features/active/` returns zero letter-anchored matches, which confirms it empirically. The fourth substitution is load-bearing only when `CoberturaProcessingState:` is `raw`, which P0-T11 and P6-T5 both explicitly authorize. Without it, `ResidualMatchCount: 0` is unreachable on a plan-authorized execution path. The two Cobertura artifacts are the expected rewrite targets, because dotnet-coverage writes absolute `` and `filename` values into them; both have already been read by P6-T6, which runs earlier, so no later task depends on their pre-substitution content. Record only the post-substitution values; do not quote the pre-substitution values in the evidence artifact itself, and do not spell the account name, the machine name, the absolute workspace-root prefix, or the two-character drive-root sequence literally in it. Rewrites land on files that earlier phase commits already committed, so they are staged and committed by P8-T22's directory-level `git add`.

Acceptance: `ResidualMatchCount: 0`, `XmlReparseFailures: 0`, and an integer `ExternalPathsRewritten:` value is present. +- [x] [P7-T1] Verify the Finding 3 production file was not touched. Run `git diff --name-only $base HEAD -- 'UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs'` and `git status --porcelain -- 'UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs'`, and record both outputs in `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/qa-gates/scope-boundary-ac17.2026-09-02T10-30.md`.

The fourth bucket exists because .claude/agent-memory/ is a tracked directory whose contents are written by the persistent-memory system of delegated agents rather than by any task in this plan, and because P0-T15 records that some such paths are already dirty before Phase 1 begins. A path may be placed in the fourth bucket only if it is under .claude/agent-memory/ or is listed in the P0-T15 `PreExistingPaths:` set; `docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md` is excluded from the fourth bucket and belongs in the third even though P0-T15 lists it. For the same reason, every path under `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729` belongs in the third bucket even though P0-T15 lists the feature folder as untracked at baseline: the P0-T15 clause admits a path to the fourth bucket, it does not compel one, and the fourth bucket's subject is agent-memory scratch. Four of those paths are no longer untracked and must be classified from the anchored diff rather than from porcelain status: `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/issue.md`, `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md`, `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/research/research-729.2026-09-02T09-30.md`, and `docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md` were committed to this branch before Phase 7 runs, so `git diff --name-status $base HEAD` reports each as an `A` entry; all four belong in the third bucket. `git status --porcelain` additionally reports `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` as modified at this point, because the revision-round-14 corrections to its Assumptions bullet, Test Strategy Finding 1 paragraph, Risks zero-delay entry, and AC5 are uncommitted until P8-T22 and P7-T7 has not yet run. That `M` entry also belongs in the third bucket. The other three paths are clean. Acceptance: exactly one path is classified as production source and it is `TaskMaster/AppGlobals/NonBlockingDelay.cs`; every other path is assigned to one of the remaining three buckets and each fourth-bucket path names which of the two allowances covers it. +- [x] [P7-T3] Verify no QuickFiler/ path changed.

Four differences are known in advance and must be named explicitly in `Deltas:` rather than left unexplained: the `spec.md` Block L insertion authored by P7-T7 and the Phase 8 acceptance-criteria checkbox edits, both of which occur after this task and therefore cannot appear in its diff; and `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/issue.md` together with `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/research/research-729.2026-09-02T09-30.md`, which are authored before this plan and are already tracked and committed on this branch, so each appears as an `A` entry in `git diff --name-status $base HEAD` rather than as an untracked path in `git status --porcelain`. `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` and `docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md` are tracked and committed on the same terms and appear as `A` entries for the same reason. `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` additionally appears as a modified path in `git status --porcelain`, carrying the revision-round-14 corrections applied before execution resumed; it is already named in the Complete file-write inventory and is therefore not an unexplained difference. Acceptance: the artifact records a `Deltas:` section that is either empty or explains every difference, and that names those two pending `spec.md` changes when the diff does not yet show them and names those two already-tracked feature-documentation paths as `A` entries in the anchored diff; the inventory contains exactly seventeen `D` entries. +- [x] [P7-T6] Write the delivery record `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/other/delivery-record.2026-09-02T10-30.md` stating (a) that `UtilitiesCS.Test/NoLiveFormInTestAssemblyTests.cs` is green from birth and is regression prevention rather than a fail-before/pass-after regression test, so no reviewer should expect a red run for it; (b) that `SVGControl.Test/NoLiveFormInTestAssemblyTests.cs` is the genuine red-before/green-after regression test, with the two evidence paths from P3-T4 and P3-T8; (c) the five final toolchain commands with their exit codes from Phase 6; (d) that Finding 4 is out of scope and carried by issue #743; and (e) a section headed `Known out-of-scope flakes:` that either states `None observed` or lists every failing QuickFiler.Test test node identifier recorded by the P6-T5 #743 re-run branch.

A ref-anchored diff is deliberately not used here. `spec.md` is tracked, and the `$base`-anchored name-status diff that P7-T2 and P7-T5 already record reports it as an addition entry, so that diff presents the whole file as added and cannot isolate this task's five inserted lines.

Record both line counts and all six search results in `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/other/spec-block-l-insertion.2026-09-02T10-30.md`. +- [x] [P7-T8] Sweep the feature folder for host identifiers before it is committed. Run a case-insensitive search over every file under `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729` for four things. The first three are fixed-string searches: the account name, derived as `Split-Path -Leaf $env:USERPROFILE`; the machine name, read from `$env:COMPUTERNAME`; and the absolute workspace-root prefix, derived at run time as `(Resolve-Path .).Path`. The fourth is a pattern search rather than a fixed-string search and serves as a residual detector only: a single ASCII letter immediately followed by the two-character drive-root sequence, that sequence constructed at run time as `([string][char]58 + [string][char]92)` so that neither this plan nor this task's own artifact contains the literal. The letter-anchored form is required because the bare two-character sequence occurs three times inside the swept file set in non-host-path contexts — twice in this plan file, where it is preceded by a straight quote and by a backtick, and once in the research artifact inside a regular-expression literal, where it is preceded by an asterisk. Rewriting any of the three would corrupt a recorded acceptance command or a research citation, and leaving them would make the acceptance below unreachable. The letter-anchored form matches none of the three and still matches every genuine absolute path. Replace every workspace-root-prefix hit with `` in its entirety — the whole absolute prefix, never only its drive-root characters, because substituting two characters inside an absolute path drives the residual count to zero while leaving the remainder of that path disclosed — and replace every account-name hit with `` and every machine-name hit with ``, using the XML-escaped forms in any `.xml`, `.cobertura.xml`, `.trx`, or `.coveragexml` artifact, because those placeholders contain angle brackets that would otherwise make the document ill-formed, and re-parse every rewritten XML-family file with `[xml](Get-Content -Raw -Encoding UTF8 $path)` to confirm it is still well-formed. After those three substitutions have been applied, replace every remaining letter-anchored absolute path — the whole path token, from its drive letter to the end of the path — with ``, using the XML-escaped form in any XML-family artifact and re-parsing it afterwards on the same terms. This fourth substitution is required because a raw, unprocessed Cobertura artifact carries third-party build-machine source paths that lie outside the workspace root and are therefore untouched by the workspace-root-prefix substitution, while still being matched by the letter-anchored residual detector: the raw dotnet-coverage output for this solution embeds `Mono.Reflection` source paths rooted at a drive-level `sources` directory. Three raw Cobertura artifacts already committed under `docs/features/active/` in this repository exhibit exactly that — `docs/features/active/2026-08-07-efcviewer-missing-lineage-and-segment-navigation-439/evidence/qa-gates/issue-439-final.cobertura.xml`, `docs/features/active/2026-08-25-quickfiler-high-confidence-partial-screen-backfill-608/evidence/qa-gates/r1-csharp-coverage.2026-08-25T12-33.cobertura.xml`, and `docs/features/active/2026-08-25-quickfiler-high-confidence-partial-screen-backfill-608/evidence/baseline/r3-csharp-coverage.2026-08-25T13-32.cobertura.xml` — each carrying 2,114 lines that the letter-anchored detector matches, of which 15 lines per artifact are the drive-level `sources` third-party paths that lie outside any workspace root and that the workspace-root-prefix substitution therefore cannot reach. A processed Cobertura carries no such path, because `scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1` lines 417-424 remove every non-allowlisted `` and rewrite each retained `class/@filename` to a repository-relative path, so this fourth substitution is a no-op there; every other `*.cobertura.xml` committed under `docs/features/active/` returns zero letter-anchored matches, which confirms it empirically.

The note states that §1.4 asserts at line 80 that `FakeTimeProvider.CreateTimer` does not invoke the callback at creation, at line 83 that a zero-due-time timer therefore fires on the next `Advance`, and at line 86 that a zero-delay test must call `fake.Advance(TimeSpan.Zero)`; that the executed run recorded in `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/regression-testing/nonblockingdelay-zero-delay-observation.2026-09-02T10-30.md` reproduced the opposite behaviour twice, with the callback invoked during `CreateTimer` for a due time of `TimeSpan.Zero`; and that `spec.md`, not §1.4, carries the governing statement.

Execution reached P6-T6 and stopped on an acceptance that correct work could not satisfy. The rest of the toolchain is green: the csharpier check is clean, both msbuild rebuilds report zero errors, and the full suite records 6955 passed and 0 failed. P6-T6 demanded an exact repository-wide greater-than-or-equal-to comparison of `line-rate` and `branch-rate`. Read directly from the two Cobertura roots, the baseline is `lines-covered=55138`, `lines-valid=64575`, `branches-covered=13187`, `branches-valid=16596`, `line-rate=0.85385985`, and the post-change document is `lines-covered=55139`, `lines-valid=64578`, `branches-covered=13186`, `branches-valid=16596`, `line-rate=0.85383567`. This change adds three instrumented lines, all of them covered, because `TaskMaster/AppGlobals/NonBlockingDelay.cs` measures 20 of 20 after the change against 17 of 17 at the baseline; adding three fully covered lines to a repository at 85.386 percent must raise the rate. The counterfactual at the post-change denominator with untouched-file movement removed is `55141/64578 = 0.85386664`, which is 0.00068 percentage points above baseline. The observed 0.0024 percentage-point drop is attributable in full to a net movement of minus two covered lines in two files this change never writes: `UtilitiesCS/Interfaces/IWinForm/PropertyStore.cs` moves from 565 of 663 to 559 of 663, and `UtilitiesCS/OutlookObjects/Table/OlTableExtensions.Etl.cs` moves from 267 of 297 to 271 of 297. Both report identical `lines-valid` on each side, so neither changed size and no source change in either is possible; the arithmetic closes exactly as `55138 + 3 - 6 + 4 = 55139`. Two independent reasons make this ambient rather than a regression: `lines-covered` is not deterministic at per-file granularity in this repository, and this change adds `[DoNotParallelize]` to two UtilitiesCS.Test classes, which by design alters execution interleaving in that assembly, so movement in concurrently exercised UtilitiesCS production code is an expected consequence of the fix working. A re-run was considered and deliberately not authorized, because selecting a favourable run from a set would make the acceptance unfalsifiable, which is the defect the plan-acceptance-gate rules exist to prevent. The remedy adds a stated tolerance band plus two new hard attribution gates rather than removing the check: P6-T6's two repository-wide rate comparisons are replaced by a four-clause acceptance whose clause 1 places an exact gate on the deterministic `lines-valid` denominator, clause 2 keeps the unchanged `NonBlockingDelay.cs` covered-over-total no-regression check, clause 3 fails on any covered-line decrease in a file this plan writes, and clause 4 bounds each repository-wide rate drop at `0.0005`; the task additionally records a counterfactual line rate whether or not it is favourable. D5's clause (a) is amended to match, with the reason recorded; D5's clause (b) and the recorded coverage-floor conflict are unchanged. Two deltas were applied and nothing else was touched: P6-T6's acceptance, and D5's clause (a). P6-T6 stays unchecked so the executor re-runs it against the revised acceptance using the two Cobertura documents already on disk; P6-T1 through P6-T5 stay checked, P6-T7 onward stay unchecked, no task was renumbered, and no AC-MAPPING entry changed. + +Citations re-derived directly against the current working tree in this pass: + +- docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/baseline/coverage-baseline.cobertura.xml line 2 — the `` root, carrying `line-rate="0.85386"`, `branch-rate="0.794589"`, `lines-covered="55138"`, `lines-valid="64575"`, `branches-covered="13187"`, `branches-valid="16596"`.

Execution reached P3-T4 and stopped: the task requires the guard's failure text to contain both the token SVGControl.Test.Form1 and the token SVGControl.Test.Form2, and a real run showed that acceptance is unsatisfiable against the assertion library's actual failure-message rendering. Block E asserts with `formDerivedTypeNames.Should().BeEmpty(because)`, and FluentAssertions 8.10.0 renders a non-empty-collection failure as `but found at least one item {}` — one representative element, never the whole collection — while Block E's `OrderBy(name, StringComparer.Ordinal)` makes Form1 win that selection deterministically, so Form2 could never appear. Both types genuinely are compiled into the pre-deletion assembly, so the red-before state is real and only the message shape was wrong. The remedy changes the guard's message rather than relaxing the acceptance: relaxing P3-T4 to a single token was considered and rejected, because spec.md line 266 AC11 independently requires the red-before run to name the two Form-derived types, so a relaxed task would leave AC11 unsatisfiable and merely move the defect. Three deltas were applied. Block E's `because` argument becomes a three-operand concatenation ending in `string.Join(", ", formDerivedTypeNames)`, so the guard enumerates every type it found. Block F, which is defined by reference as byte-identical to Block E except its namespace line, inherits the same change; a sentence under Block F now states that inheritance explicitly, and new Decisions Record entry D16 records the resulting deliberate deviation from the QuickFiler.Test model source and why spec.md line 264 AC9 and the spec.md line 76 port description, which scope "carried over unchanged" to the `GetLoadableTypes` `ReflectionTypeLoadException` fallback, are unaffected by it. Because Block E changed and P3-T1 writes it verbatim, the file on disk no longer matches the plan, so P3-T1 and P3-T3 return to unchecked. P3-T2 stays checked deliberately: it inserts a `` entry into SVGControl.Test/SVGControl.Test.csproj, that project file is untouched by the Block E change, its acceptance of exactly one match still holds, and re-running it would insert a second entry and break that very acceptance — so no future reader may re-run it. Phase 0, Phase 1, and Phase 2 checkboxes are unchanged because those phases are committed; P3-T4 onward stay unchecked and nothing is checked off by this round. No task was renumbered, no acceptance condition was altered, and no AC-MAPPING entry changed. + +Citations re-derived directly against the current working tree in this pass: + +- SVGControl.Test/NoLiveFormInTestAssemblyTests.cs lines 33-35 — the file P3-T1 wrote, carrying the pre-round-16 single-string `because` argument on line 34 at an indent of twenty spaces. This is the on-disk state that no longer matches revised Block E and is the basis for returning P3-T1 and P3-T3 to unchecked. +- Block E in this plan, the `BeEmpty` argument — the only region this round edits inside that block. The `OrderBy(name, StringComparer.Ordinal)` line, the `GetLoadableTypes` helper, its `ReflectionTypeLoadException` catch, the namespace line, and both doc comments are byte-for-byte unchanged. +- Block E sibling region, the namespace line `namespace SVGControl.Test` — re-read after the edit. It occurs exactly once in the block, and the new `because` text introduces no second occurrence, so P3-T1's first acceptance still returns exactly one match. +- Block E sibling region, the `catch (ReflectionTypeLoadException ex)` line and the four-line comment above `GetLoadableTypes` — re-read after the edit. The token `ReflectionTypeLoadException` occurs exactly once in the block; the comment does not repeat it and the new `because` text does not introduce it, so P3-T1's second acceptance still returns exactly one match. +- Block E sibling region, the `using System;` and `using System.Linq;` directives at the head of the block — re-read after the edit. `string.Join` resolves from `System` with no new using directive, so the edit adds no directive and disturbs no line P3-T1 or P4-T3 reads. +- Block F in this plan — re-read after the edit. It remains a by-reference definition naming only the namespace substitution, so both P4-T3 acceptances hold against it for the same reasons: `namespace UtilitiesCS.Test` occurs exactly once and `ReflectionTypeLoadException` occurs exactly once in the inherited text. +- UtilitiesCS.Test/ReusableTypeClasses/Concurrent/Observable/Collection/ConcurrentObservableCollectionLockRecursionTests.cs lines 49-55 — an already-CSharpier-formatted FluentAssertions call of the same shape: a receiver longer than the tab width on its own line, the chained calls beneath it, a single string-concatenation argument at the argument indent, and the `+` continuation indented four further spaces. This is the observed formatter output the new Block E text is written to match, so the Phase 6 scope-locked `csharpier format` pass rewrites nothing and the repo-wide `csharpier check` gate is unaffected. +- UtilitiesCS.Test/EmailIntelligence/MovedMailInfo_Tests.cs lines 288-294 — a multi-operand concatenation in the same position, confirming that CSharpier places every `+` operand of a chain at the same continuation indent rather than stepping each one further, which is what the three-operand Block E form assumes. +- Sibling-region check on P3-T2: SVGControl.Test/SVGControl.Test.csproj holds exactly one `` entry, inserted by the already-executed P3-T2 and unaffected by the Block E change, which is why that task alone stays checked. +- Sibling-region check on P3-T4 and P3-T8: neither task's command text or acceptance is edited by this round. P3-T4's two required tokens are now producible because the guard enumerates the collection; P3-T8's green-after acceptance is unaffected, because `string.Join` over an empty array yields an empty string and `BeEmpty` passes without rendering the message at all. +- Sibling-region check on the file-write inventory and the Decisions Record: the inventory's entries for the two created guard files are unchanged, and D16 is appended after D15 without renumbering or editing D1 through D15. + +Consistent with the round-8 through round-15 precedent, this entry's insertion shifts every line at or below it, so the internal line-number citations that rounds 6 through 15 recorded for their own entries are stale by that amount and are not corrected in this pass; each remains at the value valid in the round that wrote it. + +Revision round 15 — this round applies the eight defects the round-14 confirming preflight pass reported, one of them blocking. The blocking defect was that P2-T4 wrote its passing artifact to the exact path holding the round-14 failing-run record, which is the sole authority in the tree for Block B's zero-delay assertion and for three regions of spec.md; re-running the task would have overwritten it and stranded four committed citations, and appending was ruled out because the preserved record carries `EXIT_CODE: 1` and a duplicated `EXIT_CODE:` field is read first-occurrence-wins. P2-T4 now preserves that record by renaming it to `nonblockingdelay-zero-delay-observation.2026-09-02T10-30.md`, stamps it `ExpectedExitCode: 1`, and asserts the preserved path exists; Block B's zero-delay doc comment and the three spec.md regions were re-pointed at the new filename. The seven non-blocking deltas: P7-T7's claim that spec.md is untracked is replaced by the accurate tracked-and-`A`-entry statement; P7-T2 and P7-T5 now admit the `M` porcelain entry that spec.md carries because the round-14 corrections are uncommitted until P8-T22; the file-write inventory's spec.md parenthetical now names the round-14 corrections alongside the checkbox state and the Block L insertion; P2-T6's guard rationale is corrected, because a tracked artifact added on this branch after `$base` and then deleted produces no anchored-diff entry at all rather than an eighteenth `D`; one Planner Internal Review Record CITATION is relabelled as a historical pre-P2-T1 anchor, since the file on disk carries neither the `System.Diagnostics` using nor the Stopwatch arrangement it named; a new task P7-T9 appends a dated correction note to the research artifact, whose §1.4 lines 80, 83, and 86 assert as fact a zero-due-time behaviour this branch's own executed run falsified; and spec.md's Test Strategy 1-arg sentence now names `TimeSpan.Zero` rather than a small real interval, matching Block B. No checkbox changed: Phase 0 and Phase 1 stay checked, and every task from P2-T1 onward stays unchecked. No existing task was renumbered; P7-T9 is appended after the previous final Phase 7 task, P7-T8.

Two independent inputs forced it. First, P2-T4 was executed and failed: the scoped run recorded in docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/regression-testing/nonblockingdelay-tests.2026-09-02T10-30.md observed, deterministically and twice, that FakeTimeProvider invokes a zero-due-time one-shot timer callback during CreateTimer, so the task returned by the two-argument overload for TimeSpan.Zero is already completed when control returns. That falsifies the premise Block B's zero-delay pre-advance assertion encoded, and the premise was also stated in spec.md's Assumptions bullet, its Test Strategy Finding 1 paragraph, and its Risks entry. Second, sibling parallel item #564 merged to main while this item was stopped, and the orchestrator reconciled this branch by merging origin/main at resume, moving the merge base to 8be5a6aac3b5a82c86241fbbf989fd9118602c56. Eight deltas were applied: Block B's zero-delay method now asserts already-completion and drops its dead Advance call; Block B's class doc comment no longer embeds the literal P2-T1's own acceptance requires to be absent from that file; P2-T4's inapplicable retry branch is deleted and replaced by an explicit no-retry statement; spec.md AC5 is split so the two methods carry their separate, satisfiable assertions; the three spec prose regions are corrected to the observed behaviour with the evidence artifact cited; P7-T2, P7-T5, and the file-write inventory reclassify four now-tracked documentation paths as anchored-diff additions; a new Phase 2 task removes an unauthorized evidence artifact no task authorizes; and D11 names the re-anchored base and records that re-anchoring is the correct response to a mid-run reconciliation. Because Block B changed and P2-T1 writes it verbatim, the file on disk no longer matches the plan, so P2-T1, P2-T2, and P2-T3 are returned to unchecked. Adding one task before the Phase 2 commit task required renumbering within Phase 2 only: the commit task moved from P2-T6 to P2-T7, and the single other reference to it, in the R14 sibling-region bullet of this section, was updated in the same pass. Phase 0 and Phase 1 checkboxes are unchanged, and no Phase 3 through Phase 8 checkbox was checked. + +Citations re-derived directly against the current working tree in this pass: + +- TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs line 16 — the class doc comment clause carrying the literal that P2-T1's first acceptance requires to be absent from this same file, confirming Delta 2's contradiction is real in the tree and not only in the plan text. +- TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs lines 61-89 — the whole zero-delay method as P2-T1 wrote it.

Round 10's own note had rationalized leaving two of these in place on the theory that a path-plus-trailing-text span is not a bare whitespace-free token; that theory does not hold, since a whitespace-splitting extractor still isolates the leading path segment as its own token regardless of what non-whitespace-adjacent text follows inside the same backtick pair. All four X-entries are corrected in place: the backtick pair around each parenthetical excerpt is removed, leaving the excerpt as plain prose, matching the style already used elsewhere in this same paragraph for a citation excerpt that names a path with no single dedicated backtick span of its own. No task, phase, acceptance criterion, evidence path, git command, or Decisions Record substantive content is altered in this round. Applied directly by the orchestrator, consistent with round 12. Before finalizing, this paragraph and every location it touches were checked directly against the current tree for any remaining backtick immediately adjacent to a full or short form of any of the ten read-only paths, including forms with an intervening directory prefix between the opening backtick and the terminal filename segment — the specific gap in every prior round's narrower bare-filename-only check. None was found in either document. Revision round 12 — this round fixes the defects reported by the round-11 confirming preflight pass, applied directly by the orchestrator rather than by a further atomic-planner delegation, given the repeated recursive-defect pattern rounds 7 through 11 exhibited in their own fix-describing prose. Fixed in spec.md at four locations (the Dependencies-or-blocked-work bullet, the toolchain-commands list step 2, AC18, and the CSharpier-reformats risk bullet): each removed the backtick pair around a bare, unqualified mention of the same short filename token that names one of the ten read-only paths' final path segment, leaving every other backtick on those same lines (including any directory-qualified mention of the genuine write-target file this plan actually edits) untouched. Fixed in plan.2026-09-02T08-59.md: the round-7 W3 self-review entry, which had claimed two specific short-form mentions in line 29 (Scope Recap, Finding 3) remained backtick-wrapped, was stale — round 10 had already removed both of those backtick pairs without updating W3's own description of them. W3 is corrected to state accurately that both mentions are now unbackticked, attributing that fact to round 10's edit rather than describing it as unchanged. No task, phase, acceptance criterion, evidence path, git command, or Decisions Record substantive content is altered in this round. This entry's own text was checked before finalizing for a backtick immediately adjacent to any of the ten read-only paths or their bare/short forms; none was found, and this entry avoids repeating those forms as literal tokens at all, referring to each fix by its location and nature instead, precisely to close the recursive-reintroduction pattern that affected rounds 7, 8, 9, 10, and 11's own new prose in turn. @@ -856,7 +944,7 @@ R10. `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/rese R11. `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` — line 87 is the `### Out of scope / non-goals` bullet beginning `- **Finding 4 — pump-hosted `; it cites "four independent reasons, §4.2" but does **not** enumerate them, and a whole-file search for the four reason sentences returns zero matches.

(Per research §5 N4 these are the only two compiled `UtilitiesCS.Test` classes that capture, restore, and assert on `Console.Out` without the attribute.) +- [x] AC14 — `UtilitiesCS.Test/OutlookObjects/DASLFilterParser_Tests.cs` no longer exists on disk, and `UtilitiesCS.Test/UtilitiesCS.Test.csproj` contains no reference to it. +- [x] AC15 — A fail-before exception dossier exists at `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/regression-testing/fail-before-exception..md` for Finding 3, containing a `WhyFailingRunImpossible` section explaining that the failure requires a specific `Console.SetOut` interleaving across two threads, and citing the two in-repo precedent classes as the alternative proof of the hazard. +- [x] AC16 — Finding 4 (pump-hosted `QfcItemController` / `PumpTimeoutMs` load sensitivity) is recorded in this spec as explicitly out of scope, with the four verified reasons no test-only fix exists, and is linked to follow-up issue **#743** (docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md), including the note that the prior standalone tracker #711 was closed as superseded by #729. +- [x] AC17 — UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs is unmodified: `PrintTree` gains no `TextWriter` parameter and no other production seam is added for Finding 3. +- [x] AC18 — `TaskMaster/AppGlobals/NonBlockingDelay.cs` is the only non-test production source file modified by this change; every other modified file belongs to a test project (source, project file, or packages.config) or to this feature's documentation and evidence folder. +- [x] AC19 — No file under QuickFiler/ production sources is added, modified, or deleted. +- [x] AC20 — No file under .claude/**, .codex/**, .agents/**, config/blast-radius.json, or config/orchestration-routing.json is added, modified, or deleted. +- [x] AC21 — The full C# toolchain passes clean in a single final pass, in order: `dotnet tool run csharpier check .` reports no unformatted files; the analyzer rebuild (`/p:EnableNETAnalyzers=true /p:EnforceCodeStyleInBuild=true`) succeeds with no new diagnostics; the nullable rebuild (`/p:TreatWarningsAsErrors=true`) succeeds; and `vstest.console.exe ... /EnableCodeCoverage /InIsolation` reports zero failed tests. The commands run and their results are stated in the completion report. ## Risks & Mitigations - Technical or operational risks: - **CS0123 regression.** If the seam is implemented as an optional parameter rather than an overload pair, the solution stops compiling at StoreRehookCoordinator.cs line 102. Mitigated by AC1 (no optional parameter on either overload) and AC4 (both call sites verified compiling), and detected by the mandatory `/t:Rebuild` gates. - - **`FakeTimeProvider` zero-delay semantics.** `Advance(TimeSpan.Zero)` is expected to wake a zero-due-time waiter based on reading the upstream `WakeWaiters` implementation, but this is the one behavior confirmed by source reading rather than by an executed run. Mitigated by the documented `Advance(TimeSpan.FromTicks(1))` fallback and by the fact that the test's `[Timeout(5000)]` converts a wrong assumption into a fast, unambiguous failure rather than a hang. + - **`FakeTimeProvider` zero-delay semantics — resolved by execution, no longer open.** This was the one behavior held on source reading rather than on an executed run. The run recorded in `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/evidence/regression-testing/nonblockingdelay-zero-delay-observation.2026-09-02T10-30.md` executed it twice with the same result: `CreateTimer` invokes a zero-due-time one-shot callback during creation, so the returned task is already completed on return and `Advance` is not required. The anticipated `Advance(TimeSpan.FromTicks(1))` fallback addressed the opposite direction of error and is withdrawn. The risk is closed; `[Timeout(5000)]` remains on both tests as a deadlock bound. - **CS8632 from the nullable gate.** The 2-arg overload introduces a second nullable local. Mitigated by AC3's requirement to scope the `annotations`-only pragma pair the same way the existing code does. - **`packages/` absent from the worktree.** A build attempted before `nuget restore` fails on the `` package-restore guards rather than on the change itself. Mitigated by making `nuget restore` the first toolchain step. - **CSharpier reformats packages.config.** The formatter will rewrite the edited file, which under the repository's restart rule requires restarting the toolchain loop. Mitigated by expecting the restart rather than treating it as a failure.

The production edit is minimal and additive — one new overload, one type substitution, no behavioural change to the existing entry point. The test rewrites replace a timing-dependent assertion with a strictly stronger one. The two guard classes are correctly scoped to metadata reflection and correctly defended against a whole-assembly reflection failure. The 17 deletions were verified safe by direct search rather than by inference. + +## 1. The production seam — `TaskMaster/AppGlobals/NonBlockingDelay.cs` + +### The overload-pair decision is correct and the constraint still holds + +The change declares an explicit overload pair rather than adding an optional `TimeProvider` parameter to the existing method. The stated reason is that `WaitAsync` is consumed as a method group and an optional parameter would produce CS0123 at that site. Both halves of that were verified. + +Call-site enumeration (`grep -rn "NonBlockingDelay" --include=*.cs --include=*.csproj`) returns exactly two production call sites, matching the spec's claim: + +- `TaskMaster/AppGlobals/StoreRehookCoordinator.cs:102` — `_delay = delay ?? NonBlockingDelay.WaitAsync;` +- `TaskMaster/AppGlobals/AppEvents.cs:456` — `await NonBlockingDelay.WaitAsync(TimeSpan.FromMilliseconds(100));` + +The first is a method-group conversion. The target type is `Func?`, declared as the seventh constructor parameter of `StoreRehookCoordinator` (`StoreRehookCoordinator.cs:82`) and assigned to the `_delay` field. A method-group conversion ignores a candidate method when one or more of its optional parameters has no corresponding parameter in the target delegate type, so `WaitAsync(TimeSpan delay, TimeProvider timeProvider = null)` would leave zero applicable candidates and yield CS0123 at line 102. The constraint holds as described. Two explicit overloads restore an unambiguous one-parameter candidate. + +Confirming evidence rather than reasoning alone: `evidence/qa-gates/msbuild-analyzers.2026-09-02T10-30.md` records a fixed-string search of the analyzer rebuild log returning zero `CS0123` occurrences across 75 `CoreCompile:` executions. Neither call site was edited — neither file appears in the anchored diff. + +Note that the natural precedent for an optional-parameter seam, `UtilitiesCS/Threading/ThreadMonitor.cs`, is a *constructor*, and constructors are never converted to delegates. The reason that precedent could not be followed here is real and specific, not a preference. + +### The type substitution is faithful + +`Timer? timer = null` becomes `ITimer? timer = null`; `new Timer(callback, null, delay, Timeout.InfiniteTimeSpan)` becomes `timeProvider.CreateTimer(callback, null, delay, Timeout.InfiniteTimeSpan)`. The callback body, argument order, due time, infinite period, `TaskCompletionSource` construction, and `TaskCreationOptions.RunContinuationsAsynchronously` are all unchanged. The 1-arg overload's entire body is `return WaitAsync(delay, TimeProvider.System);`, which preserves the prior behaviour for both production call sites exactly. + +The narrowly-scoped `#nullable enable annotations` / `#nullable restore annotations` pragma pair around the nullable local is preserved. That is the right call in this file: the file has no whole-file pragma and no project-level `` element, so the narrow scope avoids conscripting the rest of the file into nullable analysis while still suppressing CS8632 on the one annotation that needs it. The nullable rebuild records zero `CS8632` and zero `CS86xx` across 55 `CoreCompile:` executions. + +The doc comment was updated honestly rather than left stale: the banned-API paragraph now names both `TimeProvider` and `System.Threading.Timer`, and a new paragraph records the CS0123 constraint so the next reader does not "simplify" the overload pair back into an optional parameter and break `StoreRehookCoordinator`. That comment is doing real work. + +### OBS-1 — `timer?.Dispose()` no-ops when the callback fires during `CreateTimer` (confirmed pre-existing, out of scope) + +Location: `TaskMaster/AppGlobals/NonBlockingDelay.cs:78-83`. + +```csharp +ITimer? timer = null; +timer = timeProvider.CreateTimer( + _ => + { + timer?.Dispose(); + tcs.TrySetResult(true); + }, + null, + delay, + Timeout.InfiniteTimeSpan +); +``` + +The callback captures `timer` before the assignment completes. When the timer fires during `CreateTimer` — or, with a real `System.Threading.Timer`, on a threadpool thread that wins the race against the assignment — `timer` is still `null`, `timer?.Dispose()` short-circuits, and the timer instance is never disposed. + +**Confirmed pre-existing.** `git show 8be5a6aac3b5a82c86241fbbf989fd9118602c56:TaskMaster/AppGlobals/NonBlockingDelay.cs` carries the identical construct at its lines 55-64, character for character apart from the concrete type. The change swaps `new Timer(...)` for `timeProvider.CreateTimer(...)` and `Timer?` for `ITimer?`; it does not introduce, widen, or narrow the race. **Refuted as a new defect; confirmed as pre-existing.** + +One qualification worth recording, because it changes what the evidence now shows rather than what the code does. The path was previously unexercised: the baseline Cobertura records `condition-coverage="50% (1/2)"` on that line. Post-change it records `condition-coverage="100% (2/2)"`. The new `WaitAsync_ZeroDelay_CompletesWithoutPump` test uses `FakeTimeProvider`, which invokes a zero-due-time one-shot timer during `CreateTimer`, so the null branch is now taken deterministically on every run. The undisposed-timer path is therefore no longer theoretical — it is demonstrated by the suite. This does not make the change responsible for the defect, and it does not make the leak newly harmful (a `FakeTimeProvider` timer holds no OS handle). It does mean a follow-up fix now has a ready-made deterministic reproduction. + +Suggested shape for the follow-up, recorded so the issue does not have to rediscover it: capture into a local before publishing, for example by assigning the `ITimer` to a local that the callback reads through a `TaskCompletionSource` continuation, or by having the callback dispose via a captured `StrongBox` written before `CreateTimer` returns. Any fix must keep the 1-arg signature intact for `StoreRehookCoordinator.cs:102`. + +**Disposition: out-of-scope observation for follow-up. Not blocking.** The bugfix minimal-change rule in the General Code Change Policy directs opening a new issue rather than widening scope, which is exactly what the correct handling is here. + +### CR-1 (advisory) — no precondition guard on `timeProvider` + +Location: `TaskMaster/AppGlobals/NonBlockingDelay.cs:66` — `public static Task WaitAsync(TimeSpan delay, TimeProvider timeProvider)`. + +A `null` argument produces a `NullReferenceException` at the `timeProvider.CreateTimer(...)` call rather than an `ArgumentNullException` naming the parameter. CLAUDE.md § C#4.3 ("Validate constructor and method preconditions") and the General Code Change Policy's fail-fast-and-explicitly rule both point at a guard here. The immediately adjacent `StoreRehookCoordinator` constructor throws `ArgumentNullException` for all seven of its dependencies, so the repository style is unambiguous on this point. + +Severity is low: the class is `internal`, the 1-arg overload always supplies `TimeProvider.System`, and the only other caller is the test project, which always supplies a `FakeTimeProvider`. There is no reachable production path that can pass null today. + +Not raised as a required change, for two reasons. First, adding a guard line would add an uncovered line to a file the spec requires at 100% coverage unless a matching negative test were also added, which is scope the plan did not authorize. Second, the bugfix minimal-change rule argues against opportunistic hardening in a defect fix. Recorded as advisory so a future edit to this file can pick it up. + +## 2. The two guard classes + +Both files were read in full. `SVGControl.Test/NoLiveFormInTestAssemblyTests.cs` and `UtilitiesCS.Test/NoLiveFormInTestAssemblyTests.cs` are byte-identical apart from the namespace line and a message improvement. + +### Verified: metadata only, nothing instantiated + +The method body is: + +```csharp +Type formType = typeof(System.Windows.Forms.Form); +Assembly executing = Assembly.GetExecutingAssembly(); +string[] formDerivedTypeNames = GetLoadableTypes(executing) + .Where(candidate => formType.IsAssignableFrom(candidate)) + .Select(candidate => candidate.FullName) + .OrderBy(name => name, StringComparer.Ordinal) + .ToArray(); +``` + +`typeof`, `Assembly.GetExecutingAssembly()`, `Assembly.GetTypes()`, `Type.IsAssignableFrom`, `Type.FullName` — every operation is metadata-level. No constructor is invoked, no `Form` handle is created, and no message pump is required. The scope is correctly limited to the executing assembly, so a referenced assembly's `Form` types cannot produce a false failure. `OrderBy(..., StringComparer.Ordinal)` makes the failure message deterministic. **Verified.** + +### Verified: `ReflectionTypeLoadException` fallback + +```csharp +private static Type[] GetLoadableTypes(Assembly assembly) +{ + try { return assembly.GetTypes(); } + catch (ReflectionTypeLoadException ex) + { + return ex.Types.Where(candidate => candidate != null).ToArray(); + } +} +``` + +Present and correct in both files. `Assembly.GetTypes()` throws for the whole assembly when any single type's dependencies fail to resolve, and `ex.Types` carries the partially-loaded set with `null` entries for the failures. Filtering the nulls degrades the guard to the loadable subset rather than leaving it permanently red for a reason unrelated to what it measures. The `catch` is narrowly typed to `ReflectionTypeLoadException` rather than broad, which satisfies the error-handling rule, and the accompanying comment explains *why* the degradation is preferred rather than restating what the code does. **Verified.** + +The degradation is a deliberate and correctly documented trade-off: a `Form`-derived type that fails to load would be silently excluded from the check. That is the right choice for a guard whose purpose is to prevent regression rather than to prove a negative under adversarial conditions, and it matches the existing precedent. + +### Fidelity to the precedent + +``` +diff QuickFiler.Test/NoLiveFormInTestAssemblyTests.cs UtilitiesCS.Test/NoLiveFormInTestAssemblyTests.cs +``` + +Two differences: the namespace, and the `because` argument. The new copies append `string.Join(", ", formDerivedTypeNames)` to the message. That is a real improvement, and a necessary one — `evidence/regression-testing/svgcontrol-guard-fail-before.2026-09-02T10-30.md` shows FluentAssertions 8.10.0 rendering only one representative item (`but found at least one item {"SVGControl.Test.Form1"}`), so without the enumeration the second offending type could never have been named. AC11 requires the red-before run to name both types; the message change is what makes that requirement satisfiable rather than a matter of luck. + +### CR-2 (advisory) — one async test does not use the fake-timer facility + +Location: `TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs:104-127`, `WaitAsync_SingleArgumentOverload_CompletesOnSystemTimeProvider`. + +The test awaits `NonBlockingDelay.WaitAsync(TimeSpan.Zero)`, which routes through `TimeProvider.System` and therefore a real `System.Threading.Timer`. `.claude/rules/general-unit-test.md` § Determinism Infrastructure states that async tests must use the framework's fake-timer facility to advance simulated time deterministically; this test advances no time and uses no fake. + +Assessed as advisory rather than a violation: + +- The due time is `TimeSpan.Zero`, so no wall-clock duration is waited on. +- The assertion is `waitTask.Status.Should().Be(TaskStatus.RanToCompletion)` — a completion assertion, not a duration assertion. The banned pattern the rule targets is a test whose *outcome* depends on elapsed real time; this test's outcome does not. +- `[Timeout(5000)]` bounds the failure mode to a diagnosable timeout rather than a hang. +- The test is required by AC6. `StoreRehookCoordinatorTests` supplies an explicit `delay` at both construction sites and never reaches the `NonBlockingDelay.WaitAsync` fallback, so without this test the 1-arg overload body would be uncovered and the file could not reach the 100% the spec requires. +- The alternative — mocking `TimeProvider.System` — is not available, and injecting a fake into the 1-arg overload would defeat the purpose of testing the 1-arg overload's own delegation. + +The residual risk is that a threadpool starved for more than five seconds would fail this test. That is a real but small exposure, and it is strictly smaller than the 30 ms `Stopwatch` comparison it replaced. The XML doc comment on the test states the reasoning explicitly, so a later reader will not mistake it for an oversight. + +No change requested. Recorded so the deviation is on the record rather than discovered later as an unexplained inconsistency. + +### CR-3 (advisory) — three identical copies of the guard class + +Locations: `QuickFiler.Test/NoLiveFormInTestAssemblyTests.cs`, `UtilitiesCS.Test/NoLiveFormInTestAssemblyTests.cs`, `SVGControl.Test/NoLiveFormInTestAssemblyTests.cs` — 56 lines each, identical apart from the namespace and (in the two new copies) the message enumeration. + +The General Code Change Policy's reusability principle argues against copy-paste. Three mitigating facts argue that duplication is the right answer here: + +1. `Assembly.GetExecutingAssembly()` must be evaluated *inside* the assembly under test. A shared helper would have to accept the assembly as a parameter, and the calling test method would still have to live in each assembly to supply it — so the shared portion would be the `GetLoadableTypes` helper and the LINQ query, roughly 25 of the 56 lines. +2. There is no shared test-support assembly that all three test projects reference. Creating one is a structural change well outside a minimal bugfix. +3. The duplication follows an existing in-repo precedent rather than establishing a new one. `QuickFiler.Test` already carried this exact file. + +A drift risk exists: the two new copies already differ from the original in their `because` argument, so the three are no longer identical. If a fourth assembly needs the guard, extracting a shared `NoLiveFormGuard.Assert(Assembly)` helper into a test-support library would be the point to do it. Recorded as advisory, not requested for this change. + +## 3. The `[DoNotParallelize]` additions + +Locations: `UtilitiesCS.Test/OutlookObjects/Filter DASL/DASLFilterParserTests.cs:8-14` and `UtilitiesCS.Test/ReusableTypeClasses/StackGeek_Tests.cs:9-15`. + +Each adds exactly seven lines — a six-line hazard comment and the attribute. The diff confirms no test body, assertion, or method name changed in either file. + +### The target-class selection was verified independently + +The spec claims these are the only two compiled `UtilitiesCS.Test` classes that capture, restore, and assert on `Console.Out` without the attribute. That is a substantive claim and it was checked rather than accepted: + +``` +grep -rln "Console.SetOut" UtilitiesCS.Test --include=*.cs -> 28 files +grep -rln "StringWriter" UtilitiesCS.Test --include=*.cs -> 10 files +``` + +The intersection is five files: `BayesianSerializationHelper_Tests.cs`, `PrettyPrint_Tests.cs`, `OlTableExtensions_Tests.cs`, `DASLFilterParserTests.cs`, `StackGeek_Tests.cs`. Inspecting each: + +- `BayesianSerializationHelper_Tests.cs` calls `Console.SetOut(new DebugTextWriter())` once in its initializer for noise suppression and never restores or asserts; its `StringWriter` uses at lines 510 and 522 are unrelated to console capture. Not a member of the set. +- `PrettyPrint_Tests.cs` (lines 196, 218) and `OlTableExtensions_Tests.cs` (lines 1640, 1645) capture, restore, and assert — and both already carried `[DoNotParallelize]` before this change. They are the two precedents the hazard comments cite. +- `DASLFilterParserTests.cs` (lines 109, 118) and `StackGeek_Tests.cs` (lines 153, 162) capture, restore, and assert — and were the only two without the attribute. + +The remaining 23 `Console.SetOut` files use the one-way `Console.SetOut(new DebugTextWriter())` initializer pattern and never assert on captured text. `NLogTraceWriter_Test.cs` is the one near-miss: it captures `originalOut` at line 22 and restores it at line 56, but it asserts through Moq callbacks rather than on captured console text, so it has no failing mode of its own. The spec records that exclusion explicitly at its out-of-scope section. **The selection is exactly right.** + +### The hazard comment corrects a stale citation, and the correction is accurate + +The two precedent comments cite `TaskMaster.runsettings` as the source of the class-level parallel scope. The new comments deliberately do not repeat that, citing `UtilitiesCS.Test/Properties/AssemblyInfo.cs` lines 18-21 instead and stating that the CI vstest invocation passes no `/Settings:` argument. + +Both halves verified: + +- `UtilitiesCS.Test/Properties/AssemblyInfo.cs` lines 18-21 are the `[assembly: Parallelize(Workers = 0, Scope = ExecutionScope.ClassLevel)]` declaration. Line numbers are correct. +- `.github/workflows/_mstest-coverage.yml:83` is `& $vstestPath $testAssemblies /EnableCodeCoverage /InIsolation /Logger:trx /TestCaseFilter:"TestCategory!=LiveOutlook"`. No `/Settings:` argument. The claim is accurate. + +Declining to propagate a stale citation into new code is the right call, and stating the correction in the comment rather than silently diverging from the precedent is the right way to do it. + +### On the absence of a red-before run + +`evidence/regression-testing/fail-before-exception.2026-09-02T10-30.md` argues that no deterministic red run is producible for Finding 3, because the failure requires a specific `Console.SetOut` interleaving across two threads that cannot be forced from test source, and because the remedy's effect is the *absence* of a nondeterministic failure, which no single run demonstrates. + +That reasoning is sound and the dossier is the right disposition. It states plainly that none is claimed rather than manufacturing a weak proxy, and it substitutes the correct alternative evidence: two in-repo precedent classes that were marked in response to this same hazard, quoted with file and line. This is a case where "no red run exists" is the honest answer and the artifact says so. + +## 4. The deletions + +17 files, verified individually. The two groups have materially different character and the change treats them correctly as different. + +**`SVGControl.Test` (6 files) — the real defect.** `Form1.cs`, `Form1.Designer.cs`, `Form1.resx`, `Form2.cs`, `Form2.Designer.cs`, `Form2.resx` were genuinely compiled: the csproj diff removes four `` entries (two carrying `Form`) and two `` entries. These are live `Form`-derived types in a unit-test assembly, which is what the guard now forbids. No test in that assembly referenced either type — confirmed by the empty grep across `SVGControl.Test`. + +**`UtilitiesCS.Test` (11 files) — orphans.** `ResourceTests.cs`, the three `Form` triplets, and `OutlookObjects/DASLFilterParser_Tests.cs` were on disk but absent from the explicit `` list in a csproj with no wildcard globbing. The `Form1 frm = new Form1();` at `ResourceTests.cs:20` that the issue cites could never execute, because the file was never compiled. The csproj diff for `UtilitiesCS.Test` is a single added line — the guard registration — with no removals, which is itself the proof that nothing was un-registered because nothing was registered. + +The change is honest about this distinction rather than papering over it: `evidence/other/scope-recap.2026-09-02T10-30.md` states that acting on the issue's literal citation alone "would satisfy the letter of the issue while leaving the actual defect untouched," and expands scope to `SVGControl.Test` for that reason. That is the correct call and the correct way to record it. + +Safety confirmed by direct search rather than inference: `grep -rn "Form1|Form2|Form3|ResourceTests"` across both test projects with `--include=*.cs --include=*.csproj --include=*.resx --include=*.config` returns empty output. The only surviving `DASLFilterParser` reference in `UtilitiesCS.Test.csproj` is line 271, pointing at the retained `OutlookObjects\Filter DASL\DASLFilterParserTests.cs`. + +## 5. Package and project file changes + +`TaskMaster.Test/TaskMaster.Test.csproj` gains two `` elements and `TaskMaster.Test/packages.config` two `` entries, for `Microsoft.Bcl.TimeProvider` 10.0.11 and `Microsoft.Extensions.TimeProvider.Testing` 10.9.0. + +Mirroring against `UtilitiesCS.Test` was verified attribute by attribute. `UtilitiesCS.Test.csproj` lines 592-593 and 644-645 carry the same `Version`, `PublicKeyToken`, `processorArchitecture`, and `lib\net462\` `HintPath` values; `UtilitiesCS.Test/packages.config` lines 23 and 91 carry the same `version` and `targetFramework="net481"`. The `net462` lib path under a `net481` target framework matches the existing `Microsoft.Bcl.AsyncInterfaces` entry, so it follows repository practice rather than introducing a new pattern. + +`TaskMaster.Test/app.config` is correctly unmodified. It already carried a `Microsoft.Bcl.TimeProvider` binding redirect at line 267 before this change — verified by grep, not assumed from the spec's assertion. `Microsoft.Extensions.TimeProvider.Testing` needs no redirect and none was added. Given that two `vstest` binaries in this repository differ in how they honour binding redirects, an unnecessary redirect edit here would have been a real risk; not making one is the right outcome. + +Both new packages are test-only.

Positive note — the evidence quality is unusually high + +Two things are worth recording because they are not the norm and they materially reduced the cost of this review: + +`evidence/qa-gates/coverage-delta.2026-09-02T10-30.md` carries a "What this artifact does not claim" section that explicitly disclaims a root cause for the `-6` covered-line movement in `PropertyStore.cs` and states that clause 3 is decided on write-set attribution rather than on causation. That is the correct handling of an unexplained observation, and it is the difference between an artifact that can be trusted and one that has to be re-derived from scratch. + +`evidence/regression-testing/svgcontrol-guard-fail-before.2026-09-02T10-30.md` explains *why* only one type name appears in the FluentAssertions "found at least one item" clause and why the `because` argument had to enumerate the collection to satisfy AC11. That is a message-shape limitation that would have looked like a discrepancy to a reviewer reading the failure text against the AC; pre-empting it saved a false finding. + +## 7.

Line 50: `public static Task WaitAsync(TimeSpan delay)`. Line 65: `public static Task WaitAsync(TimeSpan delay, TimeProvider timeProvider)`. Neither declares a default value, so neither has an optional parameter. Line 52 is the whole body of the 1-arg overload: `return WaitAsync(delay, TimeProvider.System);`. All four clauses hold. | +| AC2 | PASS | Line 78: `timer = timeProvider.CreateTimer(` with argument list `callback, null, delay, Timeout.InfiniteTimeSpan` (lines 79-86). Line 76 declares `ITimer? timer = null`, so the return type is `ITimer`, not `System.Threading.Timer`. Callback body at lines 81-82: `timer?.Dispose(); tcs.TrySetResult(true);` — both retained. Line 68: `TaskCreationOptions.RunContinuationsAsynchronously` — retained. | +| AC3 | PASS | Lines 75-77 of the head file carry `#nullable enable annotations` / `ITimer? timer = null;` / `#nullable restore annotations`. The pair is present and still scoped to the single nullable local. `evidence/qa-gates/msbuild-nullable.2026-09-02T10-30.md` records EXIT_CODE 0 with zero `CS8632` and zero `CS86[0-9][0-9]` occurrences across 55 `CoreCompile:` executions, so the gate is non-vacuous. | +| AC4 | PASS | `grep -rn "NonBlockingDelay" --include=*.cs --include=*.csproj` returns exactly two production call sites: `StoreRehookCoordinator.cs:102` (`_delay = delay ?? NonBlockingDelay.WaitAsync;`) and `AppEvents.cs:456` (`await NonBlockingDelay.WaitAsync(TimeSpan.FromMilliseconds(100));`), confirming research §5 N1's "exactly two, exactly one a method-group conversion". Neither file appears in `git diff --name-status 8be5a6aa...HEAD`, so no source change was made to either. `evidence/qa-gates/msbuild-analyzers.2026-09-02T10-30.md` records zero `CS0123` occurrences with EXIT_CODE 0. | +| AC5 | PASS | `TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs` read in full. Zero `Stopwatch` occurrences; the using set is `System`, `System.Threading`, `System.Threading.Tasks`, `FluentAssertions`, `Microsoft.Extensions.Time.Testing`, `Microsoft.VisualStudio.TestTools.UnitTesting` — no `System.Diagnostics`. `WaitAsync_WithNoDispatcher_CompletesAfterInterval` injects a `FakeTimeProvider`, asserts `waitTask.IsCompleted.Should().BeFalse(...)` before `fakeTimeProvider.Advance(interval)`, then awaits and asserts `RanToCompletion`. `WaitAsync_ZeroDelay_CompletesWithoutPump` injects a `FakeTimeProvider`, asserts `IsCompleted.Should().BeTrue(...)` immediately on return from the 2-arg overload, then awaits and asserts `RanToCompletion`. Both carry `[Timeout(5000)]`. | +| AC6 | PASS | Three test methods. The 2-arg overload is exercised by `WaitAsync_WithNoDispatcher_CompletesAfterInterval` (line 45) and `WaitAsync_ZeroDelay_CompletesWithoutPump` (line 81), both via `FakeTimeProvider`. The 1-arg overload is exercised by the dedicated `WaitAsync_SingleArgumentOverload_CompletesOnSystemTimeProvider` (line 116), which asserts `TaskStatus.RanToCompletion` — a completion assertion, not an elapsed-duration assertion, exactly as AC6 requires. Confirmed by coverage rather than by inspection alone: the post-change Cobertura carries a distinct `` element with `line-rate="1"` over its three lines (51, 52, 53), so the 1-arg body is directly covered. | +| AC7 | PASS | `TaskMaster.Test/TaskMaster.Test.csproj` diff adds `Microsoft.Bcl.TimeProvider, Version=10.0.0.11, PublicKeyToken=cc7b13ffcd2ddd51` with `HintPath` `..\packages\Microsoft.Bcl.TimeProvider.10.0.11\lib\net462\...` and `Microsoft.Extensions.TimeProvider.Testing, Version=10.9.0.0, PublicKeyToken=31bf3856ad364e35` with `HintPath` `..\packages\Microsoft.Extensions.TimeProvider.Testing.10.9.0\lib\net462\...`. `packages.config` adds both with `targetFramework="net481"`. Mirroring verified attribute by attribute against `UtilitiesCS.Test.csproj` lines 592-593 and 644-645 and `UtilitiesCS.Test/packages.config` lines 23 and 91 — identical on every field. `TaskMaster.Test/app.config` does not appear in the anchored diff; grep confirms it already carried a `Microsoft.Bcl.TimeProvider` binding redirect at line 267 before this change. | +| AC8 | PASS | All ten named paths appear as `D` entries in `git diff --name-status 8be5a6aa...HEAD`: `ResourceTests.cs`, `Form1.cs`, `Form1.Designer.cs`, `Form1.resx`, `Form2.cs`, `Form2.Designer.cs`, `Form2.resx`, `Form3.cs`, `Form3.Designer.cs`, `Form3.resx`. `find` across the worktree returns no surviving copy of any of them. | +| AC9 | PASS | File exists, `namespace UtilitiesCS.Test` at line 7. `diff` against `QuickFiler.Test/NoLiveFormInTestAssemblyTests.cs` returns two hunks — the namespace and an improved `because` argument — confirming a faithful port. The `GetLoadableTypes` `ReflectionTypeLoadException` fallback is present at lines 43-55, returning `ex.Types.Where(candidate => candidate != null).ToArray()`. Registered at `UtilitiesCS.Test/UtilitiesCS.Test.csproj` by the single added line ``. Passing status confirmed per node in `evidence/qa-gates/mstest-coverage.2026-09-02T10-30.md` (TRX `outcome="Passed"`). Green-from-birth status is stated in `evidence/other/delivery-record.2026-09-02T10-30.md` section (a), which explicitly directs that no reviewer should expect a red run for it. | +| AC10 | PASS | All six named paths appear as `D` entries. The `SVGControl.Test.csproj` diff removes four `` entries (`Form1.cs`, `Form1.Designer.cs`, `Form2.cs`, `Form2.Designer.cs`, two carrying `Form`) and two `` entries (`Form1.resx`, `Form2.resx`). `grep -n "Form1\|Form2"` against the head csproj returns zero matches. | +| AC11 | PASS | File exists, `namespace SVGControl.Test` at line 7, registered by the added ``. Passing confirmed per node (TRX `outcome="Passed"`). Red-before run recorded at `evidence/regression-testing/svgcontrol-guard-fail-before.2026-09-02T10-30.md` with `EXIT_CODE: 1`, `ExpectedExitCode: 1`, `PassedCount: 0`, `FailedCount: 1`, and failure text naming both types: `...but found: SVGControl.Test.Form1, SVGControl.Test.Form2...`. The artifact is under `.../evidence/regression-testing/` as required. | +| AC12 | PASS | `evidence/qa-gates/mstest-coverage.2026-09-02T10-30.md` records `PassedCount: 6955`, `FailedCount: 0` across 9 discovered assemblies, which entails both guards passed. Corroborated per node by two scoped single-assembly TRX confirmations, each containing exactly one `` with `outcome="Passed"` for `UtilitiesCS.Test.NoLiveFormInTestAssemblyTests.ExecutingAssembly_ContainsNoFormDerivedType` and `SVGControl.Test.NoLiveFormInTestAssemblyTests.ExecutingAssembly_ContainsNoFormDerivedType`. Two runs were needed rather than one because both assemblies declare the same class and method name and a TRX carries only the bare method name — a real limitation, correctly worked around rather than glossed. | +| AC13 | PASS | Both diffs add exactly seven lines: a six-line hazard comment plus `[DoNotParallelize]` above the existing `[TestClass]`. No test body, assertion, or method name changed in either file. The comments follow the precedent wording in `PrettyPrint_Tests.cs` (lines 14-20) and `OlTableExtensions_Tests.cs` (lines 17-21). The `AssemblyInfo.cs` lines 18-21 citation was verified: those lines are the `[assembly: Parallelize(Workers = 0, Scope = ExecutionScope.ClassLevel)]` declaration. The comments' further claim that CI passes no `/Settings:` argument was verified against `.github/workflows/_mstest-coverage.yml:83` — the invocation is `& $vstestPath $testAssemblies /EnableCodeCoverage /InIsolation /Logger:trx /TestCaseFilter:"TestCategory!=LiveOutlook"`, with no `/Settings:`. The parenthetical claim that these are the only two such classes was verified independently: the intersection of `Console.SetOut` (28 files) and `StringWriter` (10 files) in `UtilitiesCS.Test` is five files, of which `BayesianSerializationHelper_Tests.cs` uses the one-way noise-suppression pattern and does not assert, and `PrettyPrint_Tests.cs` and `OlTableExtensions_Tests.cs` already carried the attribute. | +| AC14 | PASS | `UtilitiesCS.Test/OutlookObjects/DASLFilterParser_Tests.cs` appears as a `D` entry and does not exist on disk. `grep -n "DASLFilterParser"` against `UtilitiesCS.Test.csproj` returns exactly one line — 271, `` — which points at the retained file, not the deleted one. | +| AC15 | PASS | `evidence/regression-testing/fail-before-exception.2026-09-02T10-30.md` exists at the required path. It carries a `## WhyFailingRunImpossible:` section explaining that the failure needs a specific `Console.SetOut` interleaving across two threads that cannot be forced from test source, enumerating two distinct failure modes, and stating that the remedy's effect is the absence of a nondeterministic failure. It cites both in-repo precedent classes with file, line range, and quoted source as the alternative proof. | +| AC16 | PASS | `spec.md` line 87 records Finding 4 as "explicitly and entirely OUT of scope for issue #729", enumerates the four verified reasons (lines 88-93), links issue **#743** and the path `docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md`, and states that #711 "was already closed as 'superseded by #729'". The promotion record exists on disk and is committed. Verified as substantive rather than as a citation only: the record itself carries the four reasons with source-line citations. | +| AC17 | PASS | `UtilitiesCS/OutlookObjects/Filter DASL/DASLFilterParser.cs` does not appear in `git diff --name-status 8be5a6aa...HEAD`. It is unmodified; no `TextWriter` parameter was added to `PrintTree` and no production seam was introduced for Finding 3. | +| AC18 | PASS | The anchored diff carries exactly one non-test production source file: `TaskMaster/AppGlobals/NonBlockingDelay.cs` (`M`). Every other changed path is a test-project source, a test `.csproj`, a test `packages.config`, or documentation and evidence. See the deviation note below on AC18's wording versus the `#743` promotion record. | +| AC19 | PASS | `git diff --name-status 8be5a6aa...HEAD` contains zero paths beginning `QuickFiler/`. Corroborated by `evidence/qa-gates/scope-boundary-ac19.2026-09-02T10-30.md`, which records both `git diff --name-only $base HEAD -- QuickFiler` and `git status --porcelain -- QuickFiler` returning empty. | +| AC20 | PASS | The anchored diff contains zero paths under `.claude/`, `.codex/`, `.agents/`, `config/blast-radius.json`, or `config/orchestration-routing.json`. The five dirty `.claude/agent-memory/` paths reported by `git status --porcelain` are uncommitted working-tree state written by other agents' persistent-memory systems, are absent from the anchored diff, and are recorded as pre-existing by `evidence/baseline/preexisting-worktree-state.2026-09-02T10-30.md`. AC20 governs files "added, modified, or deleted" by the change; uncommitted scratch outside the diff is neither. | +| AC21 | PASS | `evidence/qa-gates/toolchain-single-pass.2026-09-02T10-30.md` records five commands in format -> lint -> type-check -> test order, all EXIT_CODE 0, with `RewrittenFileCount: 0` establishing it as a single final pass with no re-execution trigger. `csharpier check .` was **independently re-run by this review** and returned `Checked 1571 files in 4541ms.` with no unformatted-file output and a clean exit. The analyzer rebuild reports 0 errors and 5 non-diagnostic-ID warnings, equal to baseline on all three measures. The nullable rebuild reports 0 errors and zero `CS8632`. The full suite reports `PassedCount: 6955`, `FailedCount: 0`. Both msbuild commands were checked for shape compliance: `/t:Rebuild` (not the vacuous warm `/t:Build`) and no `/p:Nullable=enable`; `CoreCompile:` counts of 75 and 55 confirm the gates are non-vacuous. Commands and results are stated in the completion report and in `evidence/other/delivery-record.2026-09-02T10-30.md` section (c). | + +## Finding-Level Coverage + +The issue consolidates four findings. Their disposition against delivery: + +| Finding | Issue citation | Disposition | Verified | +|---|---|---|---| +| 1 — `NonBlockingDelayTests.cs` awaits real wall-clock time | `TaskMaster.Test/AppGlobals/NonBlockingDelayTests.cs:38-39` | Fixed. `Stopwatch` removed; `TimeProvider` seam added as an overload pair; two of three tests now drive completion from `FakeTimeProvider` virtual time | yes — file read, coverage parsed | +| 2 — live WinForms `Form` constructed in a unit test | `UtilitiesCS.Test/ResourceTests.cs:20` | Fixed, and correctly re-aimed. The cited file was an orphan never compiled into the assembly, so fixing only it would have satisfied the issue's letter and left the defect untouched. The live defect was in `SVGControl.Test`, whose csproj genuinely compiled two `Form`-derived types. Both sites cleared; structural guards installed in each assembly | yes — csproj diffs read, red-before evidence read | +| 3 — two `Console.Out`-capturing classes lack `[DoNotParallelize]` | duplicate `DASLFilterParser*Tests.cs` | Fixed. Both classes marked with a hazard comment; the orphan duplicate deleted; the target-class selection independently re-derived and found exact | yes — full-assembly grep intersection performed | +| 4 — pump-hosted `QfcItemController` timeout under load | `PumpTimeoutMs` | Deliberately out of scope and carried forward as issue **#743**, with the promotion record committed. #711, the prior standalone tracker, was closed as superseded by #729, so #743 exists specifically to prevent the finding being dropped a second time | yes — spec, promotion record, and commit history read | + +Finding 2's re-aiming is the substantive judgement in this delivery. Acting on the issue's literal citation alone would have produced a change that passed its own acceptance criteria while leaving the real defect in place. The expansion is recorded in `evidence/other/scope-recap.2026-09-02T10-30.md` and in `spec.md` lines 74-79, with the reasoning stated rather than the expansion simply performed. + +## Deviation Recorded — AC18 wording versus the `#743` promotion record + +AC18 states that every modified file other than the single production source "belongs to a test project (source, project file, or packages.config) or to this feature's documentation and evidence folder." + +The branch adds `docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md`, which sits outside the feature folder and therefore satisfies neither literal branch of that disjunction. + +AC18 is scored PASS rather than PARTIAL, and the criterion is left checked, for the following reason. AC16 of the same spec explicitly requires that exact file to exist at that exact path, and cites it by full path. The two criteria are inconsistent with each other in wording; the delivery satisfies AC16 and satisfies AC18's substantive clause (exactly one non-test production source file modified, verified as `TaskMaster/AppGlobals/NonBlockingDelay.cs`). Unchecking AC18 would penalise the executor for a spec-authoring imprecision while the artifact on disk is exactly what the spec asked for. The imprecision is recorded as DOC-4 in `policy-audit.2026-09-03T07-30.md` § 12 so it can be corrected in the spec rather than silently carried. + +The promotion record was verified as deliberate output of this work and not incidental drift: `git log --oneline --diff-filter=A` places its addition in `3fc7fafe`, the branch's first commit, alongside the feature folder itself. + +## Known Residuals Confirmed + +The delegating prompt listed five documentation-accuracy residuals carried forward deliberately. Four were located and confirmed; they are documented in full in `policy-audit.2026-09-03T07-30.md` § 12 as DOC-1 through DOC-4, plus the coverage watch item in § 3. None affects any acceptance criterion's verdict. + +The prompt also noted that execution stopped three times on acceptance conditions correct work could not satisfy, and invited a fourth if one exists. **No fourth such condition was found.** Every acceptance condition attached to the tasks whose outputs were examined in this audit is satisfiable by correct work and was in fact satisfied. The nearest candidate is P7-T9, whose acceptance is stated in `Select-String` terms but whose results are recorded in no artifact — an auditability gap rather than an unsatisfiable condition. Its three conditions were verified directly by this review and all three hold. + +## Acceptance Criteria Status + +- Source: `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/spec.md` +- Total AC items: 21 +- Checked off (delivered): 21 +- Remaining (unchecked): 0 +- Items remaining: none +- Items unchecked by this review: none +- Items newly checked off by this review: none (all 21 were already checked and all 21 are supported by evidence) diff --git a/docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/policy-audit.2026-09-03T07-30.md b/docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/policy-audit.2026-09-03T07-30.md new file mode 100644 index 000000000..d3ba06c9c --- /dev/null +++ b/docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/policy-audit.2026-09-03T07-30.md @@ -0,0 +1,280 @@ +# Policy Audit — test-determinism-and-hygiene-debt (Issue #729) + +Timestamp: 2026-09-03T07-30 + +- Feature folder: `docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/` +- Work mode marker (from `issue.md`): `full-bug` — `spec.md` is the sole acceptance-criteria source; no `user-story.md` is expected or present. +- Item worktree audited: `C:/Users/DanMoisan/repos/TaskMaster/.claude/worktrees/agent-a7abf41824d58a80f` +- Head SHA: `e6c488bf46cec739bddcf4ee07ba070c45b85668` +- Base anchor supplied: `8be5a6aac3b5a82c86241fbbf989fd9118602c56` +- Base anchor independently re-derived: `git merge-base origin/main HEAD` -> `8be5a6aac3b5a82c86241fbbf989fd9118602c56`.

Both msbuild invocations use `/t:Rebuild` (not the vacuous warm `/t:Build`) and neither adds `/p:Nullable=enable`. This matters here because CLAUDE.md records that a warm `/t:Build` returns exit 0 with `CoreCompile` skipped on every project, which would make the gate unfalsifiable; the recorded `CoreCompile:` counts of 75 and 55 rule that out. + +Verdict: PASS. One residual note — the analyzer artifact records a `CoreCompile:` count of 75 against a baseline of 64 and states the difference was not investigated. The non-vacuity property needs only a count greater than zero, so the gate is sound; the unexplained delta is noted for completeness and is not a finding. + +## 3.

The canonical path `artifacts/csharp/coverage.xml` is absent in this worktree; the committed feature-evidence Cobertura is the substituting artifact and is treated as artifact-present. The root element of each file was read before parsing to confirm the format is Cobertura `` and not JaCoCo `` or a Visual Studio format. + +Root attributes read directly from the two XML documents by this review: + +| Measure | Baseline (`evidence/baseline/coverage-baseline.cobertura.xml`) | Post-change | Floor | Verdict | +|---|---|---|---|---| +| C# repo-wide line coverage | `line-rate="0.85386"` (85.386%) | `line-rate="0.853836"` (85.3836%) | >= 85% | PASS | +| C# repo-wide branch coverage | `branch-rate="0.794589"` (79.4589%) | `branch-rate="0.794529"` (79.4529%) | >= 75% | PASS | +| `lines-covered` / `lines-valid` | 55138 / 64575 | 55139 / 64578 | — | — | +| `branches-covered` / `branches-valid` | 13187 / 16596 | 13186 / 16596 | — | — | + +Modified-file C# coverage for the one production file changed. The `` element was located in both documents (line 187182 in each) and its `lines/line` children were counted directly, per the known trap that an `.//line` selector double-counts because method rows re-enumerate the same lines: + +| Measure | Baseline | Post-change | Verdict | +|---|---|---|---| +| `line-rate` attribute | `1` | `1` | PASS | +| `branch-rate` attribute | `0.5` | `1` | PASS (improved) | +| `lines/line` children | 17, all `hits="1"` | 20, all `hits="1"` | PASS | +| Line coverage | 17/17 = 100% | 20/20 = 100% | >= 85% floor: PASS; no changed-line regression: PASS | + +All three lines added by the 2-arg overload are covered. The single conditional line in the file (the `timer?.Dispose()` null-conditional) moved from `condition-coverage="50% (1/2)"` at baseline to `condition-coverage="100% (2/2)"` post-change, which is the source of the class-level branch-rate improvement from 0.5 to 1. + +New-code C# coverage. No new production source file was added by this change, so the new-file tier has no member. The two new files are test sources (`UtilitiesCS.Test/NoLiveFormInTestAssemblyTests.cs`, `SVGControl.Test/NoLiveFormInTestAssemblyTests.cs`) and are correctly outside the coverage denominator under the General Unit Test Policy's permitted test-file exclusion. + +### Adjudication of the repository-wide rate movement + +The repository-wide line rate fell by 0.000024 (0.0024 percentage points) and the branch rate by 0.000060 (0.0060 percentage points). Both post-change figures independently clear their absolute floors, so no policy gate turns on the movement. The attribution recorded in `evidence/qa-gates/coverage-delta.2026-09-02T10-30.md` was verified against the two XML documents and is arithmetically closed: `55138 + 3 - 6 + 4 = 55139` and `64575 + 3 = 64578`. The only file whose `lines-valid` changed is `NonBlockingDelay.cs` (+3), and it is the sole production entry in the plan's write inventory. The only file with a negative covered-line movement is `UtilitiesCS/Interfaces/IWinForm/PropertyStore.cs` (-6), which this change never touches and whose `lines-valid` is 663 on both sides. + +**On the `P6-T6` reshape.** The delegating prompt asked for an explicit position on the reshape of P6-T6 from an exact `>=` comparison into four clauses with a stated `0.0005` tolerance band. This review does not disagree with the reshape, for three reasons stated so a later reader can re-derive the position rather than take it on trust: + +1. An exact `>=` on a cross-session repository-wide constant is not a sound gate in this repository. C# repo-wide coverage constants here are non-deterministic at per-file granularity across sessions, and gating on exact comparison converts measurement noise into a false FAIL. The four-clause form replaces the unsound comparison with three deterministic clauses (denominator attribution, changed-file no-regression, write-set attribution) plus one bounded tolerance clause, which is strictly more informative than the single comparison it replaced. +2. The tolerance clause is not load-bearing for policy compliance. Both post-change figures clear the absolute 85% and 75% floors on their own. If clause 4 were struck entirely, the coverage verdict in this audit would be unchanged. The reshape therefore did not lower any gate the repository actually enforces. +3. The reshape did not weaken the clause that could hide a real defect. Clause 3 fails if any file in the write inventory shows a covered-line decrease — a strictly stronger condition than a repo-wide `>=`, because a repo-wide aggregate can mask a per-file regression that clause 3 cannot. + +Residual watch item: the `-6` movement in `PropertyStore.cs` is attributed but not root-caused. The artifact states this limitation explicitly rather than claiming a cause it did not establish, which is the correct disposition; separating run-to-run variance from a consequence of the `[DoNotParallelize]` scheduling change would need at least one further full-suite coverage run. Recorded as a watch item, not a finding. + +### Deviation: PR context artifacts are stale + +`artifacts/pr_context.summary.txt` is a tracked file in this repository and the copy present on this branch describes a different feature entirely: + +``` +Head ref (resolved): bug/claude-md-cites-ciyml-for-moved-toolchain-commands-564 @ fafe3d4d1f5a3dfcd2c44d21245d085e4156faea +Range: 5ebaaf105d8241f309f704d1ff90af2e32e5a6c1..fafe3d4d1f5a3dfcd2c44d21245d085e4156faea +``` + +`git ls-files --error-unmatch artifacts/pr_context.summary.txt` confirms it is tracked.

The pre-advance non-completion assertion proves the task cannot complete early, which the prior elapsed-time check could not. + +One advisory deviation is recorded in the code review as CR-2: `WaitAsync_SingleArgumentOverload_CompletesOnSystemTimeProvider` awaits a real `TimeProvider.System` timer rather than a fake one. It is required by AC6 to cover the 1-arg overload, uses `TimeSpan.Zero` as the due time, asserts completion rather than duration, and is bounded by `[Timeout(5000)]`. It is advisory rather than a violation of the ban on wall-clock waits, because no elapsed real time is waited on or asserted. + +## 5.

Tonality — PASS + +The changed source comments, the spec, and all 31 evidence artifacts were read or sampled. The register is factual and neutral throughout.

Claims are matched to evidence: `evidence/qa-gates/coverage-delta.2026-09-02T10-30.md` carries an explicit "What this artifact does not claim" section disclaiming a root cause it did not establish, and `evidence/regression-testing/fail-before-exception.2026-09-02T10-30.md` states plainly that no deterministic red run is producible and that none is claimed. Both are correct applications of the evidence-first wording rule. + +## 12. Documentation Accuracy — PARTIAL (non-blocking) + +Four bookkeeping inaccuracies were found. None affects delivered behaviour, none is a code defect, and none blocks.

Nothing else belongs in this list". +The list enumerates 27 entries (1 production source, 5 test sources, 4 project files and manifests, 17 deletions). The anchored diff carries 81 paths. The feature documentation, all 31 evidence artifacts, and the `#743` promotion record are absent from the list. The section is accurate as a *code* write set and inaccurate as the "every file" claim its own heading makes. +Disposition: non-blocking. The omitted paths are documentation and evidence, all of which are independently and correctly enumerated in `evidence/other/changed-file-inventory.2026-09-02T10-30.md`. + +**DOC-2 — two stale claims that the `#743` promotion record is staged by P8-T22.** +Locations: `plan.2026-09-02T08-59.md` line 112 ("It is real output of this work rather than incidental drift, so P8-T22 stages and commits it") and line 666 (P8-T22 prescribing `git add ... docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md`). +Verification: `git log --oneline --diff-filter=A -- docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md` returns `3fc7fafe docs(729): prepare feature folder and atomic plan for test-determinism-and-hygiene-debt`, the branch's first commit. The record was already tracked and committed nine commits before P8-T22 ran, so that `git add` was a no-op for this path. +Disposition: non-blocking. The file is present, committed, and correctly cited by `spec.md` line 87 and by AC16. Only the plan's description of how it got there is stale. `plan.2026-09-02T08-59.md` line 920 (S9) also classifies it as untracked, but S9 explicitly labels itself a planning-time reconstruction with recorded uncertainty, so it is not counted as a third stale claim. + +**DOC-3 — P7-T9 records its verification results in no artifact.** +Location: `plan.2026-09-02T08-59.md` line 639. +P7-T9 appends a correction note to the research artifact and states three `Select-String` acceptance conditions, but writes no evidence file. The only on-disk trace that its acceptance was evaluated is the plan checkbox itself, which is self-attesting. +This review verified the three conditions independently rather than accepting the checkbox: +- `grep -c "Correction (2026-09-03) — §1.4 zero-due-time premise falsified by execution" research-729.2026-09-02T09-30.md` -> `1` +- `grep -c "this is the single point in the plan that must be confirmed by an actual test run" research-729.2026-09-02T09-30.md` -> `1`, so the no-rewrite witness is intact and no existing line was rewritten +- The appended note contains no drive-root or host path, confirmed by the feature-folder-wide host-path scan in section 9, which returned empty +Disposition: non-blocking. The task's output is correct; only its auditability is thin. Verified here instead. + +**DOC-4 — AC18 and AC16 are internally inconsistent in wording.** +Location: `spec.md` line 278 (AC18) and line 276 (AC16). +AC18 states that every modified file other than the one production source "belongs to a test project (source, project file, or packages.config) or to this feature's documentation and evidence folder." `docs/features/potential/promoted/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam.md` is added by this branch and sits outside the feature folder, so it satisfies neither literal branch of AC18's disjunction. The same spec's AC16 explicitly requires that file to exist at that exact path. +Disposition: non-blocking, and AC18 is scored PASS rather than PARTIAL in the feature audit. The substantive clause of AC18 — exactly one non-test production source file modified — is satisfied. The file AC18's wording fails to cover is one the same spec mandates in AC16, so the delivery is in-spec and only the AC prose is imprecise. Recording a FAIL here would penalise the executor for a spec-authoring gap while the delivered artifact is exactly what the spec asked for. + +## Assumptions Recorded + +1. The C# coverage artifact obligation is treated as satisfied by the committed `/evidence/qa-gates/coverage-final.cobertura.xml` in the absence of the canonical `artifacts/csharp/coverage.xml`. Both documents were parsed directly by this review, so the substitution rests on read evidence rather than on an assertion that a file exists somewhere. +2. The analyzer, nullable, and full-suite test gates were verified from committed evidence rather than re-executed. Re-running a three-rebuild plus 6955-test loop is outside the check-only posture this review is required to keep, and evidence verification from existing artifacts is the prescribed model. The format gate was cheap enough to re-run and was re-run. +3. The governing coverage floors are taken from `.claude/rules/general-unit-test.md` and `.claude/rules/quality-tiers.md` (line >= 85%, branch >= 75%, uniform across T1-T4). CLAUDE.md § UT2 still states a repository-wide floor of 80% with 90% for new modules; that documented conflict remains unreconciled repo-wide and is out of scope for this item. The delivered figures clear both readings on every measure, so the conflict is not decisive here.
