The file previously mixed a bare host-bound script body with three +helper functions; every guard, error message, and ordering decision was unreachable from a test. +It now follows the shape its sibling `Invoke-MSTestWithCoverage.ps1` already used: helpers, a +named main function, and a two-line dot-source-guarded entry point. That is the structure +`.claude/rules/general-unit-test.md`'s Coverage Exclusion Policy explicitly prescribes, and it +moved the file from 68.89% to 94.00% command coverage with only three commands left uncovered, +all of them irreducibly host-bound. + +**Seam discipline — correct.** `Get-VsTestConsolePath` follows the wrapper-function seam pattern +in `.claude/rules/powershell.md` section "Design Seams", matching the existing `Invoke-VsTestExe` +in the same file and `Invoke-VsWhereExe` in the sibling. No injectable-delegate or runner framework +was introduced, which the rules discourage. + +**Reuse — the stated goal is met.** `Get-CoberturaPackageLineSummary` has exactly the two callers +the spec named: `Get-CoberturaCoverageSummary` sums one summary per package into the document +totals, and `Merge-CoberturaClassesByFilename` recomputes a package's rates after the merge. The +rounding expression and the `'0'` zero-denominator fallback are byte-identical to the ones the +document-level summarizer already used, which is the invariant the spec's Boundaries section +required. + +**File placement — driven by a hard constraint, correctly resolved.** Two production files and two +test files exist only because `Helpers.ps1` (492 lines) and `Helpers.Tests.ps1` (498 lines) had no +room. Choosing `Assert-CoberturaLineCoverageThreshold` as the extraction unit was the right pick: +it is the only function in Helpers.ps1 with no in-file caller and no in-file dependency, so the +move is a pure relocation with no coupling consequence, and its tests moved with it into a matched +sibling name. + +**Documentation quality — above the repo norm.** Every new function carries comment-based help with +`.SYNOPSIS`, `.DESCRIPTION`, `.PARAMETER`, and `.OUTPUTS`. The comments explain *why* (the +500-line ceiling, the return-enumeration hazard, the safe failure direction) rather than restating +*what*, which is what `.claude/rules/general-code-change.md`'s Naming section asks for. + +## Correctness Review of Each Production Change + +### Finding 1 — package rate recomputation (Helpers.ps1 lines 397-401) + +Placed at the end of the per-package loop, after every filename group in that package has been +merged and after the stale class nodes have been removed, so the recomputation sees the final +class set. Ordering inside `ConvertTo-KoverageCoberturaXml` is also correct: `Merge-...` at line +440 runs before `Get-CoberturaCoverageSummary` at line 453, so the document rate is derived from +merged content. Verified by reading, and pinned by the extended assertions in "computes the merged +per-file line-rate from the merged rollup alone". + +### Finding 2 — union-append of `` (Helpers.ps1 lines 299-307) + +Deep-clones every non-primary group member's `./methods/method` children into the merged class's +methods node, with no deduplication key, matching the spec's explicit prohibition. Correct. + +The double-count risk this creates was checked and does not materialise: +`Get-CoberturaClassLineSummary` enumerates the class-level rollup and the method-level view into +one map keyed by line number, resolving repeats by maximum hits. The union'd method lines therefore +merge with, rather than add to, the class rollup. Confirmed by reading lines 190-232 and by the +`LinesValid | Should -Be '2'` assertion in the new overload-collision pinning test, where four +`` elements across two classes reduce to two counted lines. + +`Where-Object { $_ -ne $primaryNode }` relies on reference equality between `XmlElement` instances. +That holds here because both sides come from the same `$group` array built from one `SelectNodes` +call. Correct, though implicit. + +### Finding 3 — `.claude` discovery exclusion (Invoke-MSTestWithCoverage.ps1 line 301) + +One added clause in the existing style, inside the existing `@(...)` wrapper, which is unchanged. +The regex `'\\\.claude\\'` requires a full path segment (backslash on both sides), so it will not +match a project literally named something ending in `.claude`. Correct and minimal. + +### Findings 5 and 6 — ClosureFilter.ps1 documentation + +Comment-only, zero executable lines changed. The finding-6 addendum names both failure directions +explicitly and records why a signature re-key is infeasible, which is exactly what the plan's P3-T2 +acceptance required. The prose is accurate against the code it describes. + +### Finding 7 — `Get-MSTestAssemblyPathList` (Invoke-MSTest.ps1 lines 97-127) + +The plan's task P4-T4 specified `return @(...)`. The implementation is `return , @(...)`. + +The reviewer verified the semantics independently in a clean `pwsh -NoProfile` session rather than +accepting the executor's account: + +``` +function a { return @() } -> caller receives $null +function b { return , @() } -> caller receives Object[] of Count 0 +function c { return @('x') } -> caller receives System.String +function d { return , @('x') } -> caller receives Object[] of Count 1 +``` + +and, under `Set-StrictMode -Version Latest`, `.Count` on both a bare `String` and on `$null` throws +`PropertyNotFoundException`. The plan's literal `return @(...)` would therefore not have fixed +finding 7 at all: the array would have been unwrapped again at the return boundary and +`$testAssemblies.Count` at line 181 would still throw on a single-match run. **The deviation is not +merely warranted, it is required for the fix to work.** + +Documentation of the deviation is adequate: the function's `.DESCRIPTION` at lines 107-108 states +"A function return enumerates its output, which would unwrap the array again, so the unary comma +below is what delivers the same array shape to the caller." The evidence artifact +`case-10-assembly-discovery-array-shape-discriminating.2026-09-02T22-57.md` records a two-run +measurement with the comma removed, in which the two shape assertions fail and the three older +`@($result).Count` assertions pass. + +### The `Invoke-MSTestMain` extraction and the dot-source guard + +Every guard, `throw` message, ordering decision, and the `-NoExecute` early return were compared +line by line against the pre-change body and are semantically unchanged; `$PSScriptRoot` became an +injectable `ScriptRoot` parameter defaulting to `$PSScriptRoot`, which is the only substantive +difference and is the seam that makes the guards testable. + +The new entry point is `if ($MyInvocation.InvocationName -ne '.') { Invoke-MSTestMain @PSBoundParameters }`. +The reviewer checked every caller in the repository for a regression: + +- `.vscode/tasks.json` line 179-180 invokes with `pwsh -File scripts/vscode/Invoke-MSTest.ps1`. +- `.codex/codex-web-setup.sh` line 343 invokes with `pwsh -NoProfile -ExecutionPolicy Bypass -File ...`. + +Both are `-File` invocations, where `InvocationName` is the script path, so the guard passes and +`Invoke-MSTestMain` runs. No CLI regression. The three test files dot-source the script, where the +guard correctly suppresses execution — which also let `Invoke-MSTest.RunSettings.Tests.ps1` drop +its previous `try { . $script:mstestScript -NoExecute } catch { ... }` swallow-all wrapper, a real +improvement: a genuine parse or load failure will now surface instead of being written to verbose +output. + +## Test Review + +### Determinism, isolation, and independence + +- Reviewer re-ran the full suite: **92 passed, 0 failed, 0 skipped** across 10 files, Pester 5.6.1. +- Reviewer ran each of the 10 test files **individually and in reverse-alphabetical order**. Every + file produced its standalone count unchanged (2, 5, 11, 27, 12, 20, 2, 2, 5, 6 = 92). No + order dependence, no cross-file leakage. +- Two consecutive full runs produced identical counts and identical per-file coverage figures. +- Zero `Start-Sleep`, zero retries, zero timing hacks in the changed test tree. +- Zero temporary files. Every fixture is an inline here-string. The only `Set-Content` and + `Remove-Item` references in the tree are `Mock` registrations and `Should -Invoke` assertions, + all pre-existing. + +### No external process is launched + +This was checked three ways rather than assumed: + +1. By reading. `vswhere.exe` is reachable only through `Get-VsTestConsolePath`, which + `Invoke-MSTest.Main.Tests.ps1` line 61 mocks in a `BeforeEach`. `vstest.console.exe` is + reachable only through `Invoke-VsTestExe`, mocked at line 63. `Invoke-MSTestWithCoverageMain`'s + tests mock `Invoke-VsWhereExe` and `Invoke-DotnetCoverageCollection`. +2. By coverage. `Get-VsTestConsolePath`'s external pipeline at Invoke-MSTest.ps1 lines 93-94 is one + of only three uncovered commands in the entire file. If any test had launched `vswhere.exe`, + those lines would show as executed. They do not. +3. By the one apparent exception. `Invoke-MSTest.Main.Tests.ps1` line 41 calls the real + `Invoke-VsTestExe` with `-VsTestPath 'Join-Path'`. `Join-Path` is an in-process cmdlet, not an + executable; the call proves the splatting contract without spawning anything. The test's own + comment says so, and the returned value `'C:\alpha\beta'` confirms it. + +### Discriminating power of each regression test + +| Test | Can it fail on the defect it pins | Evidence | +|---|---|---| +| package rate assertions in "computes the merged per-file line-rate from the merged rollup alone" | Yes | `case-03` records the package node holding the fixture's stale `'0'` pre-fix against the asserted `'0.6'` | +| "preserves the primary class methods subtree..."

Production already handled `max(hits)` correctly; this closes a coverage gap identified by finding 4. The fixture is nonetheless well built: the second-seen entry is strictly higher, so a first-seen-wins or last-seen-wins implementation would both be distinguishable from `max()`. Disclosed in the spec's corrected scope for finding 4 | +| "excludes assemblies discovered under a .claude worktree segment" | Yes | `case-07` and `expect-fail-run-phase2` record both paths present in the captured array pre-fix | +| "retains a closure whose bare member name collides with a non-exempt overload" | **No, by design** | A characterization test pinning an accepted limitation in its safe under-exclusion direction. It cannot fail on a defect because no defect is being fixed; it fails if someone flips the behavior toward over-exclusion, which is its purpose. Disclosed in the spec's corrected scope for finding 6 | +| the three original `@($result).Count` array-safety cases | **No, on array shape** | The `@(...)` at the assertion site restores shape locally. They fail pre-fix only on `CommandNotFoundException` | +| the two `($result -is [array])` shape cases | Yes | `case-10` records a direct measurement with the comma removed: these two fail while the three above still pass | + +The executor found and closed the non-discriminating-assertion gap itself, in task H1, and recorded +the two-run proof. That is the right handling and is credited here rather than raised as a finding. + +### Test structure + +Arrange-Act-Assert is followed throughout. Every new It carries either a descriptive name that +states the scenario and expectation, or a leading comment explaining the scenario, or both. Several +comments do genuine work — for example the ClosureFilter pinning test explains why the XPath +predicate uses unescaped `<>` (predicates compare parsed attribute values) and why the line count +is scoped to the closure class's own rollup rather than counted unscoped. + +## Findings + +No blocking defect was found. The following are advisory. + +### CR-1 — Package rate is not recomputed for a package with no `` child (Low) + +`Merge-CoberturaClassesByFilename` line 267-269 `continue`s when a package has no `./classes` node, +which skips the new recomputation at lines 397-401. Such a package keeps whatever `line-rate` the +input document carried. Every other package now gets a freshly computed rate, so the document is +internally inconsistent in that one case. A package with no classes is degenerate and its correct +rate is `'0'`, which the helper would produce. Suggested change: move the recomputation above the +`continue`, or recompute in a second pass over `//package`. + +### CR-2 — Union-appended `` nodes retain their source class's stale rate attributes (Low) + +The clones appended at line 305 carry the `line-rate` and `branch-rate` the source class computed +for them. The merged class's own rate, the package rate, and the document rate are all recomputed +and are unaffected, because `Get-CoberturaClassLineSummary` derives everything from `` +elements and ignores method-level rate attributes. The exposure is limited to a downstream +Cobertura report viewer that reads method-level rates and would see values that no longer +correspond to the merged class's context. Suggested change: recompute each appended method's rate, +or state in the union-append comment that method-level rates are intentionally left as-is. + +### CR-3 — Tests mutate `$global:LASTEXITCODE` (Low) + +`Invoke-MSTest.Main.Tests.ps1` lines 67 and 139 set `$global:LASTEXITCODE` so the +`if ($LASTEXITCODE -ne 0)` guard can be exercised. `.claude/rules/powershell.md` line 31 says to +avoid global state. The mutation is hard to avoid here, since `$LASTEXITCODE` is an automatic +variable the production code reads directly, and the `BeforeEach` re-registers the mock so +within-file ordering is safe. The reviewer confirmed empirically that the file passes standalone +and that no other file's result changes with it present. Left as advisory; the alternative +(threading the exit code through another seam) would add indirection for little gain. + +### CR-4 — `Invoke-MSTest.ps1` still lacks the `.claude` discovery exclusion its sibling gained (Medium, out of scope for this item) + +Finding 3's exclusion was applied only to `Invoke-MSTestWithCoverage.ps1`, per the spec's explicit +scoping. `Get-MSTestAssemblyPathList` retains only the `bin/`, `obj`, and `ref` +clauses. The consequence is concrete: `Invoke-MSTest.ps1 -SearchRoot .` run from the repository +root — which is exactly what `.vscode/tasks.json` line 181-182 does — will discover and run test +assemblies built inside `.claude/worktrees/` agent worktrees. The two scripts now have +asymmetric discovery semantics, which is a maintenance hazard. + +This is not a defect in the delivered change: the spec, the plan's Scope Prohibitions, and the +issue all scope finding 3 to the coverage script only, and widening it here would have been an +out-of-scope edit. Recommend promoting it to its own issue rather than leaving it as prose in a +feature folder that disappears at merge. + +### CR-5 — `Get-CoberturaCoverageSummary` package enumeration narrowed (Informational) + +The loop changed from `$packagesNode.ChildNodes` filtered to Element nodes, with +`$pkg.SelectNodes('.//class')`, to `$packagesNode.SelectNodes('./package')`. For valid Cobertura +these are equivalent, since `` has only `` children. A non-`package` element +child would now be silently skipped rather than searched for descendant classes. No behavior change +against any real input; noted only so the narrowing is on the record. + +### CR-6 — Evidence artifact line citation has drifted (Informational) + +`case-10-...md` cites `Invoke-MSTest.ps1` line 100 for the `return , @(...)` statement; it now sits +at line 120. The citation was almost certainly accurate when written at 22:57, before the +`Invoke-MSTestMain` extraction at roughly 23:21 shifted the file. Harmless, but a reader following +the citation today lands in the wrong place. + +### CR-7 — Two comment-only inaccuracies (Informational) + +The `Get-CoberturaPackageLineSummary` `.SYNOPSIS` says it "Reduces one Cobertura `` element +to a deduplicated line and branch summary." The deduplication happens inside +`Get-CoberturaClassLineSummary`, per class; this function only sums those results. The wording is +defensible but slightly overstates what this function does. + +### CR-8 — Pre-existing absolute host paths with an account name in a test fixture (Medium, pre-existing) + +`tests/scripts/vscode/Invoke-MSTestWithCoverage.Helpers.Tests.ps1` lines 41, 42, 104 and 124 embed +`C:\Users\\repos\TaskMaster` and `C:\Users\\repos\TaskMaster-wt-2026-07-04-12-57` +as fixture data. The reviewer confirmed by `git show origin/main:...` that all four are present +verbatim at the identical line numbers on the base branch. **Not introduced by this change**, and +the file's other changes are two assertion updates elsewhere in the file. + +Every fixture path added by this change uses the synthetic `C:\repo\...` form, which is the correct +pattern. Recommend a separate cleanup issue to convert the four pre-existing occurrences to the +same synthetic form; converting them here would have been an unrelated edit. + +## Best-Practice Checklist + +| Practice | Verdict | +|---|---| +| Simplicity first, no clever indirection | PASS.

The +new `Get-CoberturaPackageLineSummary` is a pure in-memory XML accumulation over nodes the caller +already walks, and P1-T10's refactor replaced an inline per-class loop with a call to it rather +than adding a second traversal. The union-append loop and package rate recomputation operate on +the same already-loaded `XmlDocument`. The `.claude` filter clause adds one regex test to an +existing `Where-Object` predicate. `Get-MSTestAssemblyPathList` moves an existing pipeline into a +function without changing what it enumerates. The iteration-3 remediation adds no operation +either: `Invoke-MSTestMain` executes the same commands the top-level body executed, and +`Get-VsTestConsolePath` wraps the same single `vswhere.exe` invocation.

Zero-match and multiple-match discovery — `AssemblyDiscovery.Tests.ps1`, plus the two + shape-reading cases that make the zero case non-vacuous. +3. Fail-safe under-exclusion direction — `ClosureFilter.Tests.ps1` "retains a closure whose bare + member name collides with a non-exempt overload", asserting `LinesValid` = `'2'` and + `LinesCovered` = `'1'`, which pins both the retention and the denominator effect. + +Additional negative paths verified beyond those cited: four `Should -Throw -ExpectedMessage` cases +in `Main.Tests.ps1` covering missing search root, missing `vswhere.exe`, unresolved +`vstest.console.exe`, and empty discovery. + +### AC4 (spec.md line 176) — "No unintended behavior changes outside the defined scope." + +**Verdict: PASS. Newly checked off by this review** in `spec.md` line 176 and, correspondingly, +plan task P5-T9. + +The executor left this unchecked because the plan's literal P5-T9 mechanism — a repository-root +`git status --porcelain` requiring every reported path to fall under one of three prefixes — +reports three `.claude/agent-memory/orchestrator/` paths. The reviewer ruled on the substantive +criterion, which is what the AC text states, using evidence re-derived rather than accepted. + +**Command 1, anchored footprint, reviewer-run.** `git diff origin/main...HEAD --name-only` returns +63 paths.

That is benign, +because origin/main at 8be5a6aa already contains every merged sibling commit, so merged sibling +content appears on both sides of the comparison and is excluded. The footprint is this item's own +work only. + +This check is capable of failing. Had any commit on this branch touched a path outside the three +prefixes, it would appear in the 63 and be counted in the "outside all three" row. + +**Command 2, porcelain status, reviewer-run.** Four paths are reported at review time: + +``` + M .claude/agent-memory/orchestrator/MEMORY.md +?? .claude/agent-memory/orchestrator/powershell-change-budget-override-for-consolidated-issue.md +?? .claude/agent-memory/orchestrator/pwsh-blanket-blocked-in-isolated-worktree-for-orchestrator.md +?? docs/features/active/2026-09-02-.../evidence/qa-gates/ac4-scope-boundary-anchored-diff.2026-09-03T01-40.md +``` + +The fourth is under an allowed prefix.

The +committed footprint contains zero paths outside the defined scope, proven by a check that could +have failed. The three porcelain-reported paths are uncommitted, third-party, and demonstrably +untouched, so they are neither behavior changes nor changes by this item. AC4 is satisfied. + +The plan's P5-T9 mechanism was a reasonable proxy when authored, under a state where nothing had +been committed; it became the weaker of the two available checks once the commit existed. Ruling on +the criterion rather than the proxy is the correct disposition, and the substituted check is +strictly stronger, not weaker. + +Two evidence defects attach to this AC and are recorded in the policy audit as PA-3, PA-4 and PA-5: +the supporting artifact is uncommitted, its filename timestamp is future-dated by 124 minutes, and +its prefix distribution (51/6/6) is wrong against the reviewer's recount (49/6/8). None affects the +ruling; the load-bearing claim was independently reproduced. + +### AC5 (spec.md line 177) — "Required logs/telemetry updated and validated (if applicable)." + +**Verdict: PASS, Not Applicable.** Already checked; the check-off is supported. + +`spec.md` line 149 states "Logging/telemetry updates (if any): None." The reviewer verified the +stronger claim behind the check-off: the two `Write-Host` calls in `Invoke-MSTest.ps1` are the only +log statements anywhere in the changed production surface, and their message text is byte-identical +to the base branch (`"Using vstest.console: $vstestPath"` and +`"Discovered $($testAssemblies.Count) test assemblies."`), moved from lines 119-120 to 185-186 only +because the enclosing body was relocated. No log statement was added, removed, or reworded. + +### AC6 (spec.md line 178) — "Performance constraints met or explicitly waived with rationale." + +**Verdict: PASS, explicitly waived.** Already checked; the check-off is supported. + +Citation `spec.md` lines 132-133 ("N/A — no latency/throughput/memory constraint applies"). The +reviewer verified the supporting rationale by reading: `Get-CoberturaPackageLineSummary` traverses +`.//class` nodes the caller already walked, and `Get-CoberturaCoverageSummary` was refactored to +delegate to it rather than add a second traversal, so the document-level pass does not double its +work. The `.claude` clause adds one regex test to an existing predicate. `Get-MSTestAssemblyPathList` +and `Invoke-MSTestMain` relocate existing statements without adding operations. Measured suite +duration moved from 15.78s over 70 tests to roughly 19s over 92 tests in the reviewer's run, +consistent with 22 additional cases and two additional files in the coverage denominator. + +### AC7 (spec.md line 179) — "Full toolchain pass completed (format → lint → type-check → test)." + +**Verdict: PASS.** Already checked; the check-off is supported, with one disclosure carried +forward. + +| Step | Final-iteration artifact | Reviewer confirmation | +|---|---|---| +| Format | evidence/qa-gates/poshqc-format.iter3.2026-09-02T23-23.md | 21 of 21 SHA-256 hashes identical before and after; the artifact's line-count table matches the reviewer's independent measurement of all 14 footprint files exactly | +| Lint | evidence/qa-gates/poshqc-analyze.iter3.2026-09-02T23-25.md | Reviewer re-ran `Invoke-ScriptAnalyzer`: 16 diagnostics, 13 Warning + 3 Information, **0 Error**, set-identical to the P0-T6 baseline modulo line-number shift.

The gate +signal relied on is the per-file diagnostic set comparison, not the exit code. The uniform gate in +`.claude/rules/quality-tiers.md` is "Lint errors: 0", and the Error count is 0 at head. This +check-off is not stronger than that evidence. + +### AC8 (spec.md line 180) — "Docs/config references updated to match the new behavior." + +**Verdict: PASS.** Already checked; the check-off is supported. + +All three cited locations were read at head and are present: + +1. `ClosureFilter.ps1` `.DESCRIPTION`, paragraph beginning "That non-admission is an asserted + design choice rather than a measured one (issue #733 finding 5)".

The same function only clones the PRIMARY class's ``, not a real merge.** `$mergedClassNode = $primaryNode.CloneNode($true)` then only ensures a `` node exists — it never unions method entries from the other classes being merged into the group. Confirmed unchanged. *(Source: #530.)* + +**3. `Invoke-MSTestWithCoverage.ps1`'s assembly-discovery filter has no `.claude` exclusion.** The `Where-Object` filter (~line 296-302) checks for `\bin\\`, excludes `\obj\` and `\ref\`, but has no exclusion for paths under `.claude\` (e.g. agent worktrees), so a stray build under an agent worktree can be discovered and counted. Confirmed unchanged. *(Source: #531.)* + +**4. No test exercises the `max(hits)` overwrite branch in the line-merge logic.** In the same merge function, `$existingNode.SetAttribute('hits', [string]([math]::Max(...)))` has no fixture where the SECOND-seen class-level entry has a higher hit count than the first (all existing fixtures present hits already `>=` later entries). *(Source: #537.)* + +**5. `Invoke-MSTestWithCoverage.ClosureFilter.ps1`: local functions are deliberately excluded from the coverage presence set.** Its own doc comment says local functions (`g__Local` members) are "deliberately NOT admitted" — confirmed present verbatim (~line 154). This is stated as intentional but its correctness as a policy is unverified; a local function inside a covered member currently cannot be measured for coverage exclusion purposes at all. *(Source: #559.)* + +**6. The same script's presence set is keyed by member NAME, not full signature.** The set is `Dictionary<"$declaringType|$filename", HashSet[string] of member names>` (~line 140, 168-169) — two overloads with the same name under the same declaring type/file collide in the set, so excluding one overload silently excludes both. *(Source: #560.)* + +**7. `Invoke-MSTest.ps1`'s single-assembly discovery pipeline throws under `StrictMode` on exactly one match.** `Get-ChildItem ... | Where-Object {...} | Select-Object -ExpandProperty FullName` (~line 107-113) is not wrapped in `@(...)`, so when the filter matches exactly one assembly, the pipeline collapses to a bare scalar string rather than an array; a later `.Count` read then throws under `Set-StrictMode -Version Latest`/`2.0+`, since a bare scalar has no native `.Count` member once the adapted-property fallback is disabled. The sibling script (`Invoke-MSTestWithCoverage.ps1`, finding 3 above) has the identical unwrapped-pipeline shape but is less likely to hit the single-match edge case since it typically discovers the whole suite. *(Source: #713.)* + +## Logs / Screenshots + +- [ ] Attached minimal logs or screenshot +- Snippet: n/a — see file/line citations inline above, each independently re-verified against `origin/main` before this consolidation. + +## Impact / Severity + +- [ ] Blocker +- [ ] High +- [x] Medium +- [ ] Low + +Medium: finding 7 is a real crash under `-SearchRoot` matching exactly one assembly (already tracked as a live blocker on a related item this session), and findings 1/2/6 silently corrupt coverage reporting numbers rather than crashing — both classes matter for trusting this repo's coverage gates, but neither is a build-breaking or data-loss defect. + +## Suspected Cause / Notes + +Findings 1, 2, and 4 are all in the same `Merge-CoberturaClassesByFilename` function and likely share one fix pass. Findings 5 and 6 are both in `ClosureFilter.ps1`'s presence-set logic and likely share a second fix pass (moving from name-keyed to signature-keyed, and revisiting the local-function exclusion policy).

No full-repository scan is used anywhere in this plan. +- Because the scan_folders scope is folder-level and both folders contain files outside this plan's write set (for example scripts/vscode/Sync-PackageReferences.ps1, scripts/vscode/Invoke-VSBuild.ps1, tests/scripts/vscode/Invoke-VSBuild.Tests.ps1), every format run in this plan is followed by a git status --porcelain -- scripts/vscode tests/scripts/vscode check; any rewritten path outside this plan's write set is reverted with git checkout -- followed by that path, and the reversion is recorded, so unrelated formatter drift is never mistaken for a scope violation or silently committed. +- This plan's write set (the only paths any task may create or modify, besides FEATURE/evidence/ and FEATURE/plan.2026-09-02T12-01.md itself): scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1, scripts/vscode/Invoke-MSTestWithCoverage.ps1, scripts/vscode/Invoke-MSTestWithCoverage.ClosureFilter.ps1, scripts/vscode/Invoke-MSTest.ps1, scripts/vscode/Invoke-MSTestWithCoverage.PackageRate.ps1 (new, introduced by Phase 1 per the file-size analysis below), tests/scripts/vscode/Invoke-MSTestWithCoverage.Helpers.Tests.ps1, tests/scripts/vscode/Invoke-MSTestWithCoverage.ClosureFilter.Tests.ps1, tests/scripts/vscode/Invoke-MSTest.RunSettings.Tests.ps1, tests/scripts/vscode/Invoke-MSTestWithCoverage.PackageRate.Tests.ps1 (new, paired with the new production file), and conditionally tests/scripts/vscode/Invoke-MSTest.AssemblyDiscovery.Tests.ps1 (only if Phase 4's size check requires the split). The new production file is a necessary consequence of the 500-line ceiling in .claude/rules/general-code-change.md and .claude/rules/powershell.md, which is a hard, non-negotiable constraint that takes precedence over spec.md's stated file-placement preference when the two conflict; spec.md's substantive requirement (one new pure per-package rate helper, reused by both the document-level summarizer and the merge function) is fully honored, only its file placement is adjusted for size. + +### Change Budget Override + +.claude/rules/powershell.md's Change Budget section states a per-batch cap in all modes of at most 3 production files and 3 test files unless an explicit override has been approved. This plan's write set exceeds that cap: it spans 5 production files (scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1, scripts/vscode/Invoke-MSTestWithCoverage.ps1, scripts/vscode/Invoke-MSTestWithCoverage.ClosureFilter.ps1, scripts/vscode/Invoke-MSTest.ps1, and the new scripts/vscode/Invoke-MSTestWithCoverage.PackageRate.ps1) and up to 5 test files (tests/scripts/vscode/Invoke-MSTestWithCoverage.Helpers.Tests.ps1, tests/scripts/vscode/Invoke-MSTestWithCoverage.ClosureFilter.Tests.ps1, tests/scripts/vscode/Invoke-MSTest.RunSettings.Tests.ps1, tests/scripts/vscode/Invoke-MSTestWithCoverage.PackageRate.Tests.ps1, and the conditional tests/scripts/vscode/Invoke-MSTest.AssemblyDiscovery.Tests.ps1). + +An explicit override has been approved by the orchestrator for this run, recorded in artifacts/orchestration/orchestrator-state.json under change_budget_override. The rationale: issue 733 is a single, user-directed, pre-scoped consolidation of seven independently-reported findings (source issues 529, 530, 531, 537, 559, 560, 713) merged into one GitHub issue since all seven are small, same-subsystem fixes confined to the scripts/vscode PowerShell MSTest/Cobertura coverage tooling. The four-file production scope and single branch/issue framing were fixed before planning began, and splitting this pre-scoped item into multiple batches would fragment one already-consolidated issue into multiple PRs, which is outside this planning pass's authority to redefine. The fifth production file is not scope creep but a mechanical consequence of the independently-verified 500-line file-size ceiling on scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1 (492 of 500 lines already used before this change, per P0-T4's measured baseline). + +## Scope Prohibitions (binding on every task in this plan) + +- Do NOT change any coverage threshold value or wire a CI coverage gate. That ownership belongs to issues #561, #562, and #563. +- Do NOT modify any file outside scripts/vscode/ and tests/scripts/vscode/, other than this plan's own evidence and plan-file paths under FEATURE. +- Do NOT apply finding 7's @(...) extraction to Invoke-MSTestWithCoverage.ps1's existing discovery block; it is already @()-wrapped (current lines 296-302) and needs no change. The extraction applies only to Invoke-MSTest.ps1. +- Do NOT attempt a signature-based re-key of the ClosureFilter.ps1 presence set for finding 6. This was evaluated and rejected as infeasible in spec.md's Root Cause Analysis: Get-CoberturaClosureDeclaringMemberName can never recover a signature from Roslyn's closure-naming convention, and forcing a signature key would flip the failure direction from safe under-exclusion to forbidden over-exclusion. +- Do NOT introduce a deduplication key into finding 2's union-append loop. +- Do NOT create temporary files anywhere, in production code, in tests, or in evidence capture. +- Do NOT modify CLAUDE.md or anything under .claude/rules/. +- Do NOT modify coverage.config, TaskMaster.runsettings, or scripts/vscode/TaskMaster.cli.runsettings. +- Do NOT modify any C# source file. + +### Phase 0 — Policy reads, feature-document reads, and PowerShell toolchain baseline + +- [x] [P0-T1] Read CLAUDE.md, .claude/rules/general-code-change.md, .claude/rules/general-unit-test.md, and .claude/rules/powershell.md in that order, per policy-compliance-order, and write FEATURE/evidence/baseline/phase0-instructions-read.TIMESTAMP.md. + - Acceptance: the artifact exists and contains Timestamp, Policy Order (the four files in the order above), and an explicit Files Read list naming each file by its repository-relative path. + +- [x] [P0-T2] Read the feature requirement documents and the current production and test files this plan touches, and write FEATURE/evidence/baseline/phase0-feature-documents-read.TIMESTAMP.md. + - Documents: FEATURE/issue.md, FEATURE/spec.md, FEATURE/research/research-findings.2026-09-02T13-15.md, scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1, scripts/vscode/Invoke-MSTestWithCoverage.ps1, scripts/vscode/Invoke-MSTestWithCoverage.ClosureFilter.ps1, scripts/vscode/Invoke-MSTest.ps1, tests/scripts/vscode/Invoke-MSTestWithCoverage.Helpers.Tests.ps1, tests/scripts/vscode/Invoke-MSTestWithCoverage.ClosureFilter.Tests.ps1, tests/scripts/vscode/Invoke-MSTest.RunSettings.Tests.ps1. + - Acceptance: the artifact exists, contains Timestamp and the explicit file list, and records "Work Mode: full-bug" and "AC Source: FEATURE/spec.md (sole source)". + +- [x] [P0-T3] Record the branch and commit baseline in FEATURE/evidence/baseline/branch-commit-baseline.TIMESTAMP.md. + - Commands: git rev-parse --abbrev-ref HEAD, git rev-parse HEAD, git status --porcelain. + - Acceptance: the artifact records the branch name, the full HEAD SHA, and the verbatim porcelain output.

No task in this plan stages or commits the plan's own changes before this task runs, so an anchored git diff against a ref would report nothing regardless of what the executor touched; git status --porcelain instead surfaces every staged, unstaged, and untracked path, including brand-new untracked files such as scripts/vscode/Invoke-MSTestWithCoverage.PackageRate.ps1 and tests/scripts/vscode/Invoke-MSTestWithCoverage.PackageRate.Tests.ps1. Confirm every reported path falls under one of exactly three allowed prefixes: scripts/vscode/, tests/scripts/vscode/, or docs/features/active/2026-09-02-coverage-cobertura-mstest-powershell-tooling-defects-733/ (the last prefix covers this task's own and sibling P5-T6 through P5-T13 AC check-off edits to the acceptance-criteria-status artifact, and any plan checkbox updates the executor itself makes). + - Acceptance: the artifact records the verbatim git status --porcelain output and confirms every reported path (staged, unstaged, and untracked) falls under one of the three allowed prefixes named above; any path outside those three prefixes fails this task's acceptance. + +- [x] [P5-T10] [AC5] Check off "Required logs/telemetry updated and validated (if applicable)." in the same artifact as Not Applicable, citing spec.md's Data / API / Config Impact section ("Logging/telemetry updates (if any): None."). + - Acceptance: the artifact records the Not Applicable determination with its citation. + +- [x] [P5-T11] [AC6] Check off "Performance constraints met or explicitly waived with rationale." in the same artifact as explicitly waived, citing spec.md's Proposed Fix section ("Performance constraints (latency/throughput/memory): N/A") and noting no new I/O or expensive operation is introduced by any of the seven findings. + - Acceptance: the artifact records the waiver with its citation and rationale. + +- [x] [P5-T12] [AC7] Check off "Full toolchain pass completed (format → lint → type-check → test)." in the same artifact, citing the clean, non-file-changing, non-failing final iteration of P5-T1, P5-T2, and P5-T4, and recording that type-check is Not Applicable for PowerShell per .claude/rules/powershell.md. + - Acceptance: the artifact cites the specific final-iteration artifact paths for format, analyze, and test. + +- [x] [P5-T13] [AC8] Check off "Docs/config references updated to match the new behavior." in the same artifact, citing the P3-T1 and P3-T2 docstring clarifications in scripts/vscode/Invoke-MSTestWithCoverage.ClosureFilter.ps1 and the P1-T12 comment correction in scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1, and confirming FEATURE/spec.md already documents the corrected, post-fix scope with no further edit required. + - Acceptance: the artifact cites both docstring/comment locations and the spec.md determination. + +## Planner Adversarial Self-Review + +Revision round: this pass applies two preflight-directed deltas (Change Budget Override subsection; P5-T9 acceptance-condition replacement) to the plan previously validated at CITATION-TO-TREE PASS. Per atomic-plan-contract, every citation this pass's edits touched is re-derived below directly against current repository state, and the sibling region around each edit is re-checked for invalidated assumptions. Citations unaffected by this round's two deltas (the Phase 0-4 findings-specific line citations) were not re-touched by this pass's edits and are not re-asserted here; they remain part of the plan's overall citation set as already recorded in the Planner Internal Review Record below. + +SELF-REVIEW: RE-DERIVED THIS PASS +- .claude/rules/powershell.md — read this pass (Change Budget section, lines 37-41); confirmed the exact per-batch cap text "at most 3 production files and 3 test files unless an explicit override has been approved" (line 40) that the new Change Budget Override subsection cites. Re-derived directly against current tree state for this pass's edit. +- artifacts/orchestration/orchestrator-state.json — read this pass (change_budget_override block, lines 67-73); confirmed approved: true, the 5-production/5-test scope description, and the rationale text (source issues 529, 530, 531, 537, 559, 560, 713; fixed four-file scope; fifth file as a mechanical consequence of the Helpers.ps1 size ceiling) that the new Change Budget Override subsection paraphrases. Re-derived directly against current tree state for this pass's edit. +- scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1 — re-read this pass (lines 480-492, tail of file); confirmed 492 total lines, matching the file-size figure the Change Budget Override subsection now cites (492 of 500, not the 491 given in the orchestrator-state.json rationale prose, which is corrected here to match the plan's own P0-T4 measured baseline rather than carried forward from the delegation prompt). +- FEATURE/plan.2026-09-02T12-01.md, Conventions section (sibling region for delta 1) — re-read lines 12-23 this pass; the existing write-set enumeration (line 23: 5 production files, up to 5 test files) is unchanged by this round and matches the counts newly stated in the Change Budget Override subsection with no discrepancy; no invalidated assumption found in the sibling Conventions bullets (lines 14-22). +- FEATURE/plan.2026-09-02T12-01.md, whole-document search for "git commit" and "git add " (basis for the P5-T9 edit) — searched this pass; zero matches found anywhere in the plan, confirming no task stages or commits the plan's own changes before P5-T9 runs, which is the load-bearing fact for replacing the anchored git diff with an unstaged-aware git status --porcelain check. +- FEATURE/plan.2026-09-02T12-01.md, Phase 5 sibling AC check-off tasks (sibling region for delta 2) — re-read P5-T1 through P5-T8 and P5-T10 through P5-T13 (lines 191-228) this pass; none of them cite the removed anchored git diff, none assume a prior commit or staging step, and none is invalidated by P5-T9's replacement. P5-T1's existing scoped git status --porcelain -- scripts/vscode tests/scripts/vscode (line 191, Conventions line 22) is a distinct, narrower, drift-detection invocation from P5-T9's new unscoped repository-root git status --porcelain; the two do not conflict. +- FEATURE/plan.2026-09-02T12-01.md, revised P5-T9 text itself — re-read after editing; confirmed the three allowed prefixes (scripts/vscode/, tests/scripts/vscode/, docs/features/active/2026-09-02-coverage-cobertura-mstest-powershell-tooling-defects-733/) collectively cover every path this plan's own tasks write to (evidence artifacts, plan checkbox edits, and the new PackageRate production/test files), so the AC4 gate is satisfiable on a compliant run and can fail on a genuine out-of-scope write. + +## Planner Internal Review Record + +PLANNER-INTERNAL-REVIEW: PASS + +CITATION-TO-TREE: PASS +- CITATION: docs/features/active/2026-09-02-coverage-cobertura-mstest-powershell-tooling-defects-733/issue.md | findings 1-7, lines 34-47 +- CITATION: docs/features/active/2026-09-02-coverage-cobertura-mstest-powershell-tooling-defects-733/spec.md | Proposed Fix design summary lines 78-92, Root Cause Analysis correction lines 72-75, Write Set lines 196-204, Acceptance Criteria lines 172-180 +- CITATION: docs/features/active/2026-09-02-coverage-cobertura-mstest-powershell-tooling-defects-733/research/research-findings.2026-09-02T13-15.md | per-finding fix proposals, section 3, lines 32-147 +- CITATION: scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1 | Get-CoberturaCoverageSummary lines 99-139; Merge-CoberturaClassesByFilename lines 262-391; methods-node handling lines 295-301; max(hits) line 329; stale comment lines 367-370; merged-class rate lines 371-375; tail/line-count check lines 480-492 +- CITATION: scripts/vscode/Invoke-MSTestWithCoverage.ps1 | Invoke-MSTestWithCoverageMain lines 248-345; discovery Where-Object filter lines 296-302 +- CITATION: scripts/vscode/Invoke-MSTestWithCoverage.ClosureFilter.ps1 | Get-CoberturaInstrumentedMemberName lines 134-209; local-function exclusion doc lines 154-157 +- CITATION: scripts/vscode/Invoke-MSTest.ps1 | function definitions lines 12-75; unwrapped discovery pipeline lines 107-113 +- CITATION: tests/scripts/vscode/Invoke-MSTestWithCoverage.Helpers.Tests.ps1 | "computes the merged per-file line-rate..." lines 238-271; "preserves the primary class methods subtree..." lines 316-349 +- CITATION: tests/scripts/vscode/Invoke-MSTestWithCoverage.ClosureFilter.Tests.ps1 | Describe 'Remove-CoberturaExemptClosureCoverage' lines 9-324, Part B lines 152-190 +- CITATION: tests/scripts/vscode/Invoke-MSTest.RunSettings.Tests.ps1 | BeforeAll lines 3-25; Describe 'Invoke-MSTestWithCoverageMain' lines 345-414 +- CITATION: .claude/rules/powershell.md | toolchain order lines 13-20; 500-line ceiling line 35; coverage floor lines 63-65; Change Budget section lines 37-41 +- CITATION: docs/features/archive/2026-08-10-excludefromcodecoverage-nested-lambdas-457/plan.2026-08-10T14-08.md | Conventions section lines 12-28 +- CITATION: artifacts/orchestration/orchestrator-state.json | change_budget_override block lines 67-73 + +AC-TRACEABILITY: PASS + +SCOPE-BOUNDARY: PASS — every write task in this plan targets a path under scripts/vscode/ or tests/scripts/vscode/, or an evidence/plan path under FEATURE, matching spec.md's Scope & Non-Goals section (lines 55-70) and the Scope Prohibitions section above.

Extracting + `Assert-CoberturaLineCoverageThreshold` brought it to 469, which the reviewer re-measured. The + function was the only one in the file with no in-file caller and no in-file dependency, so the + move is a pure relocation. The extraction is authorized in-band by P1-T14's own acceptance text, + which directs extraction into "a further sibling file" when the ceiling is exceeded. +- Helpers.Tests.ps1 measured 498 at baseline and 566 after Phase 1's additions. Two Describe-block + extractions brought it to 494, which the reviewer re-measured. Merge.Tests.ps1 and + Threshold.Tests.ps1 are those two blocks, moved verbatim. +- Invoke-MSTest.ps1 measured **68.89%** at the P0-T7 baseline, already below the 85% floor before + any change, with its 14 missed commands concentrated in the un-extracted host-bound top-level + body. `.claude/rules/general-unit-test.md`'s Coverage Exclusion Policy forbids excluding a + production file and prescribes exactly the remedy applied: extract the logic into host-neutral + testable units and leave only the thinnest wiring in the entry point. The plan's own P5-T5 + criterion (d) requires every write-set production file at or above 85%. Main.Tests.ps1 exists to + cover the extracted `Invoke-MSTestMain`. RunSettings.Tests.ps1 measured 488 lines, so the + 11 new cases could not be appended there without breaching the ceiling. + +Ruling: **the excess is a genuine consequence of two hard constraints that outrank the change +budget, not scope creep.** Every extra file is traceable to the 500-line ceiling or the 85% +coverage floor combined with the no-exclusion policy, each is confined to the two in-scope trees, +and each has a contemporaneous, checkable evidence record. Nothing in the excess advances an +unrelated goal or touches an unrelated script. + +Two qualifications are recorded so the ruling is not read as stronger than the evidence: + +1. The `Invoke-MSTestMain` and `Get-VsTestConsolePath` extraction is the one discretionary element. + No finding among the seven required it. A defensible alternative was to record the pre-existing + 68.89% as a baseline condition outside this item's causation and leave the file alone. The + executor instead applied the remedy the Coverage Exclusion Policy prescribes. That is the more + policy-faithful choice, and it is confined to one file, so `.claude/rules/powershell.md` line 92 + ("broad refactors across unrelated scripts or modules") is not engaged. Accepted. +2. The procedural defect is real: the plan's Conventions write set (line 23) and its Change Budget + Override section (lines 25-29) still describe 5 production and up to 5 test files, and the + override record in `artifacts/orchestration/orchestrator-state.json` was not amended. The + delivered scope therefore exceeds the scope a maintainer actually approved. + +Required action: the orchestrator should amend the change-budget override record to the delivered +6 production and 8 test files, citing the ceiling and floor derivations above.

They are residue from a prior occupant of this +reused worktree. Impact on this review: none, because scope and evidence were derived from the +recomputed merge base and the branch diff, which the Scope Invariant names as authoritative. Impact +downstream: real, because the PR-author flow and the coverage hook both read the summary and would +misidentify the branch and its changed languages. + +Required action: regenerate the PR context artifacts for this branch before authoring the PR. +Non-blocking for the code. + +### PA-3 — One evidence artifact carries a future-dated timestamp (PARTIAL, non-blocking) + +`evidence/qa-gates/ac4-scope-boundary-anchored-diff.2026-09-03T01-40.md` claims 2026-09-03T01-40 in +both its filename and its header. Its actual filesystem write time is 2026-09-02T23:35:31 local, and +the reviewer's clock at audit time reads 2026-09-02T23:49. The claimed timestamp is 124 minutes +ahead of the write time and is not the UTC rendering either (UTC at write time was +2026-09-03T03:35). The value is therefore synthetic. + +Every other artifact was checked the same way. The remaining drifts are 7 to 21 minutes and are +explainable by an artifact recording a command time and being finalised or amended later; none is +future-dated by more than a few minutes. + +Content impact: none. The artifact's two commands were independently re-run by this reviewer and +its substantive conclusion is correct. The defect is hygiene only. + +Required action: correct the timestamp to the real write time when the artifact is committed. + +### PA-4 — AC4 evidence artifact is uncommitted (PARTIAL, non-blocking) + +`evidence/qa-gates/ac4-scope-boundary-anchored-diff.2026-09-03T01-40.md` is untracked. It is the +sole evidence supporting the AC4 disposition, and this reviewer is checking AC4 off (see the +feature audit). The artifact, together with the spec.md and plan.md checkbox edits this review +makes, must be committed before the PR is authored, or the branch will carry a checked AC with no +in-branch evidence. + +Required action: commit the AC4 artifact and this review's checkbox edits.

It sets the merged class's own `line-rate`/`branch-rate` (Helpers.ps1:371-375) by duplicating the same rounding expression as `Get-CoberturaCoverageSummary`, with an explicit code comment (Helpers.ps1:367-370) stating this duplication is deliberate because "the spec specifies exactly one new helper" — i.e., a prior work item intentionally avoided adding a second helper for the merged-class rate. That constraint does not extend to a package-scoped helper, which is a different aggregation (across all classes in a package, not one merged class). +- `Invoke-MSTestWithCoverageMain` (Invoke-MSTestWithCoverage.ps1:248-345) is a **testable wrapper function** around the whole coverage pipeline (discovery → collect → post-process). Its assembly-discovery block (lines 296-302) is **already wrapped in `@(...)`**: `$testAssemblies = @(Get-ChildItem ... | Where-Object {...} | Select-Object -ExpandProperty FullName)`. This confirms the issue's own instruction: finding 7's fix does **not** apply to this script, only to `Invoke-MSTest.ps1`. +- `Invoke-MSTest.ps1` has **no such wrapper function** — its body (lines 80-131) is bare top-level script code that runs unconditionally on dot-source or direct invocation (there is no `$MyInvocation.InvocationName -ne '.'` guard, unlike the coverage script). Its discovery block (lines 107-113) is **not** wrapped in `@(...)`, confirming finding 7 as stated. Its `vswhere.exe` invocation (line 102, `& $vswherePath -latest ...`) is also called **directly**, not through a mockable wrapper — unlike the coverage script, which has `Invoke-VsWhereExe` specifically for testability. This is a structural asymmetry between the two scripts (not one of the seven findings, noted here only because it affects test-strategy design for finding 7, below). +- `ClosureFilter.ps1`'s `Get-CoberturaInstrumentedMemberName` (lines 134-209) builds a presence hashtable keyed by `"$declaringType|$filename"` → `HashSet<string>` of **bare member names**, admitted from two sources: (1) plain `<method name="X">` on a non-synthesized class where X doesn't start with `<`; (2) the `<Member>` token parsed from an async/iterator state-machine class name `Type.<Member>d__<N>`. `<Member>g__Local|N_M` (local functions) are explicitly and deliberately **not** admitted (documented rationale at lines 154-157). +- `Get-CoberturaClosureDeclaringMemberName` (lines 38-97) is the **consumer-side** regex lookup used when walking closure classes: it recovers only a bare member-name token from four Roslyn name shapes (`<M>b__...`, `<M>g__Local|N_M`, `Type.<M>d__N`, `...<<M>b__K>d`). **None of its capture groups ever recover a parameter signature or count** — Roslyn's closure/lambda naming convention does not encode the enclosing member's signature. + +## 2. Existing Pester Test Conventions (verified by reading both files in full) + +- Both existing Helper/ClosureFilter test files dot-source the production script directly in `BeforeAll` (`. $helperScriptPath`) — no module manifest, no `Import-Module`. +- Cobertura fixtures are inline here-strings (`[xml]$doc = @'...'@` or `$inputXml = @'...'@` passed to `ConvertTo-KoverageCoberturaXml`), always minimal, single-purpose, and heavily commented with an explicit "Regression case N (Issue #NNN, ...)" note tying the fixture to the specific direction of the defect it pins. +- Assertions use FluentAssertions-style Pester `Should` (this is native Pester `Should`, not a C# FluentAssertions port — the repo's C# assertion-library rule does not apply to PowerShell). +- `tests/scripts/vscode/Invoke-MSTest.RunSettings.Tests.ps1` is the **only** existing test file that imports **both** `Invoke-MSTest.ps1` (via `. $script:mstestScript -NoExecute`) and `Invoke-MSTestWithCoverage.ps1` (via `[System.Management.Automation.Language.Parser]::ParseFile(...).GetScriptBlock()`, dot-sourced, because the coverage script's own trailing invocation guard would otherwise run `Invoke-MSTestWithCoverageMain` for real). It already contains a `Describe 'Invoke-MSTestWithCoverageMain'` block (lines 345-414) that mocks `Resolve-Path`, `Test-Path`, `Resolve-RunSettingsPath`, `Invoke-VsWhereExe`, `Get-Command`, `Get-ChildItem`, `Invoke-DotnetCoverageCollection`, `Get-Content`, `ConvertTo-KoverageCoberturaXml`, `Set-Content`, and calls `Invoke-MSTestWithCoverageMain` directly with `-NoExecute`/`-ScriptRoot`. This is the natural, already-proven scaffold for finding 3's regression test. +- No file currently named `Invoke-MSTestWithCoverage.Tests.ps1` or `Invoke-MSTest.Tests.ps1` exists. Given the discovery above, **new dedicated files are not required** for findings 3 or 7 — `Invoke-MSTest.RunSettings.Tests.ps1` already dot-sources both target scripts and already exercises the exact function (`Invoke-MSTestWithCoverageMain`) or exact top-level body (`Invoke-MSTest.ps1`) that findings 3 and 7 touch. Extending this existing file, rather than creating new ones, follows the file's own established, working pattern and avoids duplicating the mock/import scaffolding. + +## 3. Per-Finding Fix Proposals + +### Finding 1 — package-level `line-rate`/`branch-rate` never recomputed +**Function/location:** `Merge-CoberturaClassesByFilename`, `scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1` (merge loop ~262-391). + +No existing helper computes a rate scoped to a single `<package>` — `Get-CoberturaClassLineSummary` is class-scoped and `Get-CoberturaCoverageSummary` is document-scoped (sums over *all* packages). A new small pure helper is needed. Recommended shape, placed beside `Get-CoberturaCoverageSummary` in Helpers.ps1: + +``` +function Get-CoberturaPackageLineSummary { + param([Parameter(Mandatory = $true)][System.Xml.XmlElement]$PackageNode) + # Same accumulation loop as Get-CoberturaCoverageSummary's inner `foreach ($cls in ...)`, + # scoped to one <package> via $PackageNode.SelectNodes('.//class'), returning the same + # pscustomobject shape (LineRate, BranchRate, LinesCovered, LinesValid, BranchesCovered, BranchesValid). +} +``` + +`Get-CoberturaCoverageSummary` should then be refactored to call this new helper once per package and sum its outputs — this removes the current inline duplication and gives the new package-level helper the same "already proven by the document-level totals" trust the class-level helper has. In `Merge-CoberturaClassesByFilename`, after the inner `foreach ($filename in $filenameGroups.Keys)` loop finishes for a given `$packageNode` (i.e., immediately before the outer `foreach ($packageNode in ...)` closing brace), call the new helper on `$packageNode` and `SetAttribute('line-rate', ...)` / `SetAttribute('branch-rate', ...)` on the package node itself, mirroring the exact rounding/zero-fallback expression already used for both class-level and document-level rates. + +**Test target:** `tests/scripts/vscode/Invoke-MSTestWithCoverage.Helpers.Tests.ps1` — add a new `Describe 'Get-CoberturaPackageLineSummary'` block (mirroring the existing `Describe 'Get-CoberturaClassLineSummary'` block's style), plus extend the existing `ConvertTo-KoverageCoberturaXml` merge tests (e.g. the "merges duplicate class entries..." or "computes the merged per-file line-rate..." fixtures) with an assertion on the resulting `<package>` node's `line-rate`/`branch-rate` attributes. + +### Finding 2 — merged class drops non-primary group members' `<methods>` +**Function/location:** `Merge-CoberturaClassesByFilename`, same file, lines 295-301 (methods-node handling) inside the per-filename-group loop. + +Fix: after ensuring `$methodsNode` exists, iterate the **other** members of `$group` (every class node except `$primaryNode`, whose subtree — including its own `<methods>` — is already present via `CloneNode($true)`) and append a deep clone of each `./methods/method` child into `$methodsNode`: + +``` +foreach ($classNode in $group) { + if ($classNode -eq $primaryNode) { continue } + foreach ($methodNode in @($classNode.SelectNodes('./methods/method'))) { + [void]$methodsNode.AppendChild($methodNode.CloneNode($true)) + } +} +``` + +No dedup key is proposed: Roslyn generates distinct method-name tokens per closure/lambda/local-function/state-machine, so two different group members (declaring class + its `<>c`/`<>c__DisplayClassN_M` closures) cannot legitimately share an identical `<method name=...>` value in the same filename group under normal compiler output. This assumption should be verified by the atomic-plan/test author with a 3+-way merge fixture (declaring class + two distinct closure classes, each contributing a differently-named method) rather than assumed silently. + +**Materially important:** this fix will **change the outcome of an existing, currently-passing regression test.** `Invoke-MSTestWithCoverage.Helpers.Tests.ps1`'s test `'preserves the primary class methods subtree and every hits value when merging'` (lines 316-349) contains the comment *"Locks the decision not to merge or strip `<methods>`."* and asserts `$methodNodes.Count | Should -Be 1` with only method `'M'` present — i.e., it currently asserts, as an intentional prior design decision, exactly the behavior finding 2 identifies as a defect (dropping the closure class's method `'N'`). Fixing finding 2 requires **updating this existing test's assertions** (methodNodes.Count should become 2, containing both `'M'` and `'N'`), not merely adding a new one. Per CLAUDE.md §7.3 ("Treat existing unit tests as part of the spec"), this reversal of a previously locked-in decision should be called out explicitly to the downstream `prd-feature`/atomic-planner authors as a deliberate, spec-approved behavior change, not a silent edit. + +**Test target:** same file — modify the existing test above, and add a new isolated test for a 3-member merge group exercising the union/no-dedup-collision case. + +### Finding 3 — no `.claude\` exclusion in `Invoke-MSTestWithCoverage.ps1` discovery filter +**Function/location:** `Invoke-MSTestWithCoverageMain`, `scripts/vscode/Invoke-MSTestWithCoverage.ps1`, lines 296-302 (already inside a testable function — no extraction needed). + +Fix: add a fourth `-and` clause to the existing `Where-Object` predicate: `-and $_.FullName -notmatch '\\\.claude\\'` (backslash-escaped literal dot, consistent with the existing `\\bin\\`, `\\obj\\`, `\\ref\\` clauses' style). + +Note (informational only, not proposed for this issue): `Invoke-MSTest.ps1`'s own discovery block (lines 107-113) has the identical unfiltered shape and would benefit from the same clause for parity, but finding 3 as scoped in the issue names only `Invoke-MSTestWithCoverage.ps1`; expanding to the sibling script would be a scope decision for the `prd-feature`/planning stage, not this research. + +**Test target:** `tests/scripts/vscode/Invoke-MSTest.RunSettings.Tests.ps1`, extending the existing `Describe 'Invoke-MSTestWithCoverageMain'` block. Add an `It` that mocks `Get-ChildItem` to return two items — one ordinary `...\bin\Debug\Foo.Test.dll` path and one under `...\.claude\worktrees\...\bin\Debug\Bar.Test.dll` — and mocks `Invoke-DotnetCoverageCollection` to capture its `-TestAssembly` parameter (same capture pattern already used for `Invoke-DotnetCoverageExe`/`Invoke-VsWhereExe` elsewhere in this file), asserting only the non-`.claude` path is forwarded. + +### Finding 4 — no dedicated fixture for the "second-seen strictly higher hits" merge branch +**Function/location:** `Merge-CoberturaClassesByFilename`, line 329 (`SetAttribute('hits', Max(...))`). + +**Conclusion: this is a test-only gap, not a code defect**, but the existing coverage is less direct than it first appears and should be clarified rather than assumed adequate: +- The existing focused test `'deduplicates a repeated line number by taking the maximum hits value'` (Helpers.Tests.ps1:273-294) exercises `Get-CoberturaClassLineSummary`'s **own**, separately-implemented max-hits logic (plain property assignment `$existing.Hits = $hits`, not `SetAttribute`) — its fixture has only one `<class>` element, so `Merge-CoberturaClassesByFilename`'s per-group merge is skipped entirely (`$group.Count -le 1` guard, line 286-288) for that fixture. It does not exercise line 329 at all. +- The multi-purpose test `'merges duplicate class entries that point to the same source file'` (Helpers.Tests.ps1:53-95) **does** incidentally exercise line 329 in the exact "second-seen strictly higher" direction (class1's line 11 hits=0 is first-seen in `$group` document order; class2's line 11 hits=1 is second-seen and higher), and asserts `$line11.hits | Should -Be '1'`. However this fixture conflates that assertion with several unrelated behaviors (path normalization, branch promotion, condition-coverage, complexity summation), so it is not an isolated, single-purpose regression pin per the repo's own testing standard ("Write focused tests exercising a single function or behavior," `.claude/rules/powershell.md`). + +Recommendation: no production code change; add one new, minimal, focused fixture to `Helpers.Tests.ps1` with exactly two classes sharing a filename, exactly one overlapping line number, and only the hits value varying (second class strictly higher), asserting the merged line's `hits` attribute. This closes the audit gap identified by the static review without touching production code. + +### Finding 5 — local-function exclusion policy documented but unratified +**Function/location:** `Get-CoberturaInstrumentedMemberName`, `scripts/vscode/Invoke-MSTestWithCoverage.ClosureFilter.ps1`, lines 154-157 (doc comment) / 194 (enforcement — the `foreach` over `./methods/method` only calls `.Add($methodName)` when the class is non-synthesized, which structurally cannot include a `g__` local-function name emitted on the declaring type's own class without deliberately special-casing it, which the code does not do). + +**Conclusion: no code change required.** Evidence: +- The current behavior is already pinned by an existing, passing test: `ClosureFilter.Tests.ps1`'s `'removes a closure class outright when every method resolves to an absent member'` (lines 152-190), Part B, whose comment explicitly states *"a `g__` local function on the declaring type does not admit 'Exempt'."* +- Direction-of-failure analysis: not admitting `g__` tokens pushes outcomes toward **exclusion** (dropping coverage) whenever a closure's declaring member resolves only via a local-function token. For a genuinely `[ExcludeFromCodeCoverage]`-attributed outer member, this is the correct, desired outcome. A counter-example where this would cause **over-exclusion** (the one forbidden failure direction per the function's own documented fail-safe invariant) requires a non-exempt method that emits **only** a `g__` local-function method entry and no plain top-level `<method>` element of its own — no such counter-example was found or constructed during this research, and none is cited in the issue. +- The issue's own framing agrees: it is flagged as a policy whose correctness is "unverified," not as a demonstrated behavior defect, and explicitly does not request a policy change. + +Recommendation: treat as a documentation clarification only. Add a short addendum to the existing docstring (lines 154-157) noting that the exclusion is an asserted design choice, not independently verified against a live counter-example, and that it should be revisited if a genuine non-exempt-method-with-only-a-`g__`-entry case is ever observed. No new test is strictly required (existing Part B already pins current behavior), though a one-line comment cross-referencing issue #733 on the existing test would help future readers understand why the policy exists. + +### Finding 6 — presence-set keyed by bare member name, not full signature +**Function/location:** `Get-CoberturaInstrumentedMemberName`, same file, lines 178-205 (presence-set construction, `HashSet[string]` of bare names). + +**Data-availability analysis (required before proposing any re-keying):** +- **Producer side** (`Get-CoberturaInstrumentedMemberName`, source 1): a `signature` XML attribute **is** present on real Cobertura `<method>` elements (confirmed directly in existing test fixtures, e.g. `Invoke-MSTestWithCoverage.Helpers.Tests.ps1` line 281: `<method name=".ctor" signature="()" ...>` and `<method name=".ctor" signature="(int)" ...>`). This attribute is not read by the current code, so signature-based keying is technically available on this side without new regex parsing. +- **Producer side, source 2** (async/iterator state-machine class names, `Type.<Member>d__<N>`): no signature is available at all — this shape is derived purely from a class-name regex match and carries no parameter information. +- **Consumer side** (`Get-CoberturaClosureDeclaringMemberName`, used by `Remove-CoberturaExemptClosureCoverage` to resolve which declaring member a closure belongs to): **none** of its four regex capture groups (`^<(?<m>...)>b__`, `^<(?<m>...)>g__`, `<<(?<m>...)>b__\d+>d`, `<(?<m>...)>d__\d+`) ever recover a parameter signature or count. Roslyn's closure/lambda/local-function naming convention encodes only the enclosing member's *name*, never its signature. + +**Conclusion: a signature-based re-key is not achievable with the data actually available**, because even if the producer-side presence set were keyed by `"name|signature"`, the consumer-side lookup can only ever supply a bare name — `.Contains()` would then never match anything for **any** member (not just overloaded ones), flipping the outcome from the current "collision causes wrong retention" to "every lookup fails, causing mass over-exclusion of every closure in the file." That would violate the function's own explicit, documented fail-safe invariant ("over-exclusion is not an acceptable failure mode... every failure mode of the key is in the under-exclusion direction"), which is a materially worse regression than the defect finding 6 describes. + +**Direction-of-failure analysis for the current (bare-name) behavior:** because `[ExcludeFromCodeCoverage]`-attributed members emit no `<method>` element at all, a name collision between an exempt overload and a non-exempt overload of the same name causes the presence set to contain the name (from the non-exempt overload) — so the exempt overload's closures are wrongly **retained** (kept in the denominator, permanently uncovered) rather than wrongly **excluded**. This is the safe, already-fail-safe direction ("a file measures no better than it truly is"), not the forbidden over-exclusion direction. It is a real accuracy defect (unfairly penalizes coverage percentage for an exempt overload) but not a correctness-hiding one. + +Recommendation: do not attempt a functional re-keying fix (infeasible given available data on the consumer side, and any attempt risks flipping the fail-safe direction). Instead: (a) document this residual limitation directly in the `Get-CoberturaInstrumentedMemberName` docstring (mirroring the existing style used for the local-function exclusion note), explicitly naming the direction of the effect (safe/under-exclusion, not over-exclusion) so a future reader does not attempt an unsafe fix; (b) add one focused pinning regression test demonstrating the current, documented, safe-direction outcome for a same-name-overload collision (one exempt overload, one non-exempt overload, same declaring type/file) so the behavior cannot silently drift in the unsafe direction without a test failing. + +**This conclusion materially contradicts spec.md's current seeded test-strategy line** ("re-key the presence set by full member signature instead of bare name" — spec.md Test Strategy, item 3). The `prd-feature`/atomic-planner stage should be made aware of this before finalizing acceptance criteria, since the seeded approach is not implementable with the data available in the Cobertura report as currently consumed by this script. + +### Finding 7 — `Invoke-MSTest.ps1` unwrapped discovery pipeline throws under StrictMode +**Function/location:** `Invoke-MSTest.ps1`, lines 107-113 (top-level script body, no wrapper function). + +Fix (minimal): wrap the pipeline in `@(...)`, exactly matching the pattern already used in the sibling script: +``` +$testAssemblies = @(Get-ChildItem -Path $resolvedSearchRoot -Recurse -Filter '*.Test.dll' | + Where-Object { ... } | + Select-Object -ExpandProperty FullName) +``` + +**Testability constraint discovered:** unlike `Invoke-MSTestWithCoverage.ps1`, this script's discovery block is bare top-level code, not inside a callable function, and its `vswhere.exe` invocation (line 102) is a direct `&` call with no mockable wrapper (unlike the coverage script's `Invoke-VsWhereExe`). A test that dot-sources the *entire* script to reach line 115 would need `Test-Path` to return `$true` for the vswhere-exists check (line 98) in order to proceed to discovery, which then causes the real, unmocked `& $vswherePath ...` call at line 102 to execute for real — there is no way to intercept it via `Mock` alone, since `Mock` matches by command name and the invocation target is resolved from a variable at runtime, not a literal command name Pester can bind to. + +To make finding 7 both fixed and reliably regression-tested without expanding scope into a broader script refactor, extract only the discovery-and-count logic (lines 107-117) into a small, testable function, following this file's own established wrapper-function pattern (`Get-VsTestArgumentList`, `Invoke-VsTestExe`) and the repo's documented Design Seams guidance ("introduce the smallest seam that enables reliable mocking," `.claude/rules/powershell.md`): + +``` +function Get-MSTestAssemblyPathList { + param( + [Parameter(Mandatory = $true)][string]$SearchRoot, + [Parameter(Mandatory = $true)][string]$Configuration + ) + return @(Get-ChildItem -Path $SearchRoot -Recurse -Filter '*.Test.dll' | + Where-Object { + $_.FullName -match "\\bin\\$Configuration\\" -and + $_.FullName -notmatch '\\obj\\' -and + $_.FullName -notmatch '\\ref\\' + } | + Select-Object -ExpandProperty FullName) +} +``` +with line 107 replaced by `$testAssemblies = Get-MSTestAssemblyPathList -SearchRoot $resolvedSearchRoot -Configuration $Configuration`. This keeps the fix itself minimal (the `@(...)` wrap) while making it directly and deterministically testable in isolation (mock `Get-ChildItem` to return exactly one item; assert the returned array's `.Count` is `1` without throwing), rather than requiring a fragile whole-script dot-source with an unmockable external-executable call in the path. This mirrors, at file-appropriate scale, the same testability the coverage script already has for its own (already-correct) discovery block. + +**Test target:** `tests/scripts/vscode/Invoke-MSTest.RunSettings.Tests.ps1`, which already dot-sources `Invoke-MSTest.ps1`'s definitions in `BeforeAll`. Add a new `Describe 'Get-MSTestAssemblyPathList'` block with `It`s for: zero matches, exactly one match (the StrictMode regression case — must not throw and `.Count` must equal `1`), and multiple matches, using `Mock Get-ChildItem`. + +## 4.

The same function only clones the PRIMARY class's `<methods>`, not a real merge.** `$mergedClassNode = $primaryNode.CloneNode($true)` then only ensures a `<methods>` node exists — it never unions method entries from the other classes being merged into the group. Confirmed unchanged. *(Source: #530.)* + +**3. Invoke-MSTestWithCoverage.ps1's assembly-discovery filter has no .claude exclusion.** The `Where-Object` filter (~line 296-302) checks for `\bin\<Configuration>\`, excludes `\obj\` and `\ref\`, but has no exclusion for paths under .claude\ (e.g. agent worktrees), so a stray build under an agent worktree can be discovered and counted. Confirmed unchanged. *(Source: #531.)* + +**4. No test exercises the `max(hits)` overwrite branch in the line-merge logic.** In the same merge function, `$existingNode.SetAttribute('hits', [string]([math]::Max(...)))` has no fixture where the SECOND-seen class-level entry has a higher hit count than the first (all existing fixtures present hits already `>=` later entries). *(Source: #537.)* + +**5. Invoke-MSTestWithCoverage.ClosureFilter.ps1: local functions are deliberately excluded from the coverage presence set.** Its own doc comment says local functions (`g__Local` members) are "deliberately NOT admitted" — confirmed present verbatim (~line 154). This is stated as intentional but its correctness as a policy is unverified; a local function inside a covered member currently cannot be measured for coverage exclusion purposes at all. *(Source: #559.)* + +**6. The same script's presence set is keyed by member NAME, not full signature.** The set is `Dictionary<"$declaringType|$filename", HashSet[string] of member names>` (~line 140, 168-169) — two overloads with the same name under the same declaring type/file collide in the set, so excluding one overload silently excludes both. *(Source: #560.)* + +**7. Invoke-MSTest.ps1's single-assembly discovery pipeline throws under `StrictMode` on exactly one match.** `Get-ChildItem ... | Where-Object {...} | Select-Object -ExpandProperty FullName` (~line 107-113) is not wrapped in `@(...)`, so when the filter matches exactly one assembly, the pipeline collapses to a bare scalar string rather than an array; a later `.Count` read then throws under `Set-StrictMode -Version Latest`/`2.0+`, since a bare scalar has no native `.Count` member once the adapted-property fallback is disabled. The sibling script (Invoke-MSTestWithCoverage.ps1, finding 3 above) has the identical unwrapped-pipeline shape but is less likely to hit the single-match edge case since it typically discovers the whole suite. *(Source: #713.)* + +Logs / Screenshots: +- [ ] Attached minimal logs or screenshot +- Snippet: n/a — see file/line citations inline above, each independently re-verified against `origin/main` before this consolidation. + + +## Scope & Non-Goals +- In scope: + - Finding 1: a new package-level rate-computation helper, and package-level `line-rate`/`branch-rate` recomputation after class merges, in `Merge-CoberturaClassesByFilename` (scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1). + - Finding 2: a union-append loop over non-primary group members' method nodes in the same function, so a merge unions all group methods instead of cloning only the primary class's. + - Finding 3: a .claude-path exclusion clause added to the existing assembly-discovery filter in `Invoke-MSTestWithCoverageMain` (scripts/vscode/Invoke-MSTestWithCoverage.ps1).

Findings 5 and 6 are both in ClosureFilter.ps1's presence-set logic and likely share a second fix pass (moving from name-keyed to signature-keyed, and revisiting the local-function exclusion policy). Finding 3 and finding 7 are the same missing-`@()`-array-safety class of defect in two sibling scripts. All seven independently re-verified against current `origin/main` as part of this consolidation pass on 2026-09-02. + +**Correction to finding 6's originally stated approach.** The issue text and this spec's originally seeded Test Strategy line proposed re-keying the presence set in ClosureFilter.ps1 by full member signature instead of bare name. Research determined this is infeasible: the consumer-side lookup, `Get-CoberturaClosureDeclaringMemberName`, can only ever recover a bare member name from Roslyn's closure/lambda/local-function/state-machine naming convention — it has no capture group that recovers a parameter signature or count. A signature-keyed presence set would therefore never match any consumer-side lookup, which would flip the defect from its current safe, under-exclusion direction (a name-colliding exempt overload's closures are wrongly retained in the coverage denominator, permanently uncovered) to the explicitly forbidden over-exclusion direction (excluding closures that are actually covered), violating the function's own documented fail-safe invariant. The corrected scope for finding 6 is documentation-only: a docstring clarification of the name-collision limitation and its safe direction, plus one new pinning regression test that documents the current, safe-direction collision behavior. No behavior-changing production code fix is proposed for finding 6; see Proposed Fix and Test Strategy below, which supersede the issue's literal wording. + + +## Proposed Fix + +### Design summary (what changes where): +Three independent, small fix passes, one per finding cluster, all confined to scripts/vscode/ and tests/scripts/vscode/: +1. `Merge-CoberturaClassesByFilename` fixes (findings 1, 2, 4) in Invoke-MSTestWithCoverage.Helpers.ps1: add a new pure per-package rate-computation helper, `Get-CoberturaPackageLineSummary`, reused by both the existing document-level summary function (`Get-CoberturaCoverageSummary`) and the merge function, so package-level `line-rate`/`branch-rate` are recomputed after class merges (finding 1); add a union-append loop over non-primary group members' method nodes so the merge unions all group methods instead of cloning only the primary class's (finding 2); no code change for finding 4, only a new isolated Pester fixture. +2. Discovery-filter fix (finding 3) in Invoke-MSTestWithCoverage.ps1: add one more `-notmatch` clause to the existing `Where-Object` predicate in `Invoke-MSTestWithCoverageMain` to exclude paths under a .claude directory segment, matching the existing bin/obj/ref clause style. This is a discovery-filter change only, not a coverage threshold change. +3. ClosureFilter.ps1 documentation clarifications (findings 5, 6), no behavior change: ratify the local-function exclusion policy as intentional (finding 5), and document the bare-name overload-collision limitation and its safe, under-exclusion failure direction (finding 6, corrected scope — see Root Cause Analysis above). +4. Invoke-MSTest.ps1 discovery-pipeline fix (finding 7): extract the existing bare top-level discovery pipeline into a new function, `Get-MSTestAssemblyPathList`, that wraps the pipeline in `@(...)` so a single-match result stays an array under `Set-StrictMode -Version Latest`, and call it from the script body. This applies only to Invoke-MSTest.ps1 — Invoke-MSTestWithCoverage.ps1's equivalent discovery block is already `@()`-wrapped and needs no change. + +### Boundaries and invariants to preserve: +- Do not change the safe, under-exclusion failure direction of ClosureFilter.ps1's presence-set matching for finding 6. A signature-based re-key is explicitly rejected because it would flip the failure direction to over-exclusion, which the function's own documented fail-safe invariant forbids. +- Do not alter any coverage threshold value and do not wire a CI coverage gate; that ownership belongs to issues #561, #562, and #563. +- Preserve the existing package/class/document rate-rounding and zero-denominator fallback expression pattern already used by `Get-CoberturaCoverageSummary` and the merged-class rate assignment in `Merge-CoberturaClassesByFilename`; the new package-level helper must reuse the identical rounding/fallback expression rather than introduce a divergent one. +- Preserve Invoke-MSTestWithCoverage.ps1's existing `@()`-wrapped discovery block unchanged; finding 7's fix must not be applied there. +- Keep the fix for finding 2 confined to a union-append (no deduplication key) of method nodes across the merge group, consistent with the research's finding that Roslyn generates distinct method-name tokens per closure/lambda/local-function/state-machine member within one filename group; verify this assumption with a 3+-way merge fixture during test authoring. + +### Dependencies or blocked work: +None. All seven fixes are independent of one another and of any other open item, except for the shared ownership boundary with issues #561, #562, and #563 for coverage-threshold/CI-gate work, which this item does not touch. + +### Implementation strategy (what changes, not sequencing): + +#### Files/modules to change: +- scripts/vscode/Invoke-MSTestWithCoverage.Helpers.ps1 — new package-level rate helper (`Get-CoberturaPackageLineSummary`); `Get-CoberturaCoverageSummary` refactored to call it; `Merge-CoberturaClassesByFilename` union-merge of methods and package-level rate recomputation. +- scripts/vscode/Invoke-MSTestWithCoverage.ps1 — `Invoke-MSTestWithCoverageMain`'s assembly-discovery `Where-Object` predicate. +- scripts/vscode/Invoke-MSTestWithCoverage.ClosureFilter.ps1 — docstring-only clarifications to `Get-CoberturaInstrumentedMemberName`'s existing comments. +- scripts/vscode/Invoke-MSTest.ps1 — extraction of a new `Get-MSTestAssemblyPathList` function; script body updated to call it. +- tests/scripts/vscode/Invoke-MSTestWithCoverage.Helpers.Tests.ps1 — new Describe block for the package-level rate helper; updated assertions in the existing methods-preservation test; new fixtures for the union-merge and max(hits) second-seen-higher cases. +- tests/scripts/vscode/Invoke-MSTestWithCoverage.ClosureFilter.Tests.ps1 — new pinning test for the finding-6 name-collision, safe-direction behavior. +- tests/scripts/vscode/Invoke-MSTest.RunSettings.Tests.ps1 — new Describe block for `Get-MSTestAssemblyPathList`; new It case for the .claude exclusion in the existing `Describe 'Invoke-MSTestWithCoverageMain'` block. + +#### Functions/classes/CLI commands impacted: +`Merge-CoberturaClassesByFilename`, `Get-CoberturaCoverageSummary`, a new `Get-CoberturaPackageLineSummary` helper, `Invoke-MSTestWithCoverageMain`, `Get-CoberturaInstrumentedMemberName` (docstring only), `Get-CoberturaClosureDeclaringMemberName` (referenced for the finding-6 docstring, not modified), and a new `Get-MSTestAssemblyPathList` function. + +#### Data flow and validation changes: +None of the seven findings introduce a new input/output data shape. The package-level rate helper reads the same `<package>`/`<class>`/`<lines>` Cobertura XML shape already read by the existing class- and document-level summarizers, and writes the same `line-rate`/`branch-rate` attribute pair the merged class and document nodes already carry. The discovery-filter change (finding 3) and the discovery-extraction change (finding 7) narrow or restructure which filesystem paths are considered during test-assembly discovery; neither changes the shape of the resulting assembly-path list. + +#### Error handling and logging updates: +None required. All seven fixes operate within existing error-handling and logging patterns already present in the target scripts; no new failure mode is introduced beyond the discovery-filter narrowing described above. + +#### Rollback/feature-flag considerations (if applicable): +Not applicable. These are internal developer-tooling scripts with no runtime feature-flag surface; rollback is a standard git revert of the changed files if needed. + +### Technical specifications (interfaces/contracts): +No new external interfaces. All seven fixes are internal to existing PowerShell developer-tooling scripts under scripts/vscode/ and their Pester tests under tests/scripts/vscode/; none exposes a new CLI surface, config schema, or API contract. + +#### Inputs/outputs and formats: +N/A — no new format is introduced; the Cobertura XML shape consumed and produced is unchanged. + +#### Required configuration keys and defaults: +N/A — no new configuration keys are introduced. + +#### Backward-compatibility expectations: +`Merge-CoberturaClassesByFilename`'s output gains additional method entries and package-level rate attributes it previously lacked. Downstream consumers of the merged Cobertura XML (for example, coverage report viewers) should treat this as a completeness improvement, not a breaking schema change, since the XML shape (attribute names, element structure) is unchanged. + +#### Performance constraints (latency/throughput/memory): +N/A — no latency/throughput/memory constraint applies to these developer-tooling scripts beyond existing test-run time. + +## Assumptions, Constraints, Dependencies +- Assumptions (environment, data, access): + - Two different group members merged by filename (a declaring class and its closure classes) never legitimately emit an identical `<method name=...>` value within the same merge group under normal Roslyn compiler output; finding 2's fix therefore performs a plain union-append with no deduplication key. This assumption should be spot-checked with a 3+-way merge fixture during test authoring, per the research. + - Correction to the issue's originally stated finding-6 approach: re-keying ClosureFilter.ps1's presence set by full member signature is infeasible because the consumer-side lookup, `Get-CoberturaClosureDeclaringMemberName`, can never recover a signature from Roslyn's closure-naming convention. This spec supersedes the issue's literal wording for finding 6 with a documentation-only fix, per Root Cause Analysis above. + - Finding 5's local-function exclusion policy is treated as ratified and intentional based on the research's direction-of-failure analysis (no over-exclusion counter-example was found or constructed); this spec does not request further behavior investigation. +- Constraints (budget, performance, compatibility): + - All work is confined to scripts/vscode/ and tests/scripts/vscode/; no coverage threshold value, CI gate wiring, or file outside these two trees may be touched. + - No Python tooling exists in this repository; all tests for this item are Pester under tests/scripts/vscode/. +- External dependencies (services, libraries, releases): + - None. No new library, service, or release dependency is introduced by any of the seven findings. + +## Data / API / Config Impact +- User-facing or API changes: None. This item touches internal developer-tooling scripts only. +- Data or migration considerations: None. +- Logging/telemetry updates (if any): None. +- Compatibility notes (CLI flags, config schemas, versioning): N/A — no CLI flag or config schema changes; see Backward-compatibility expectations under Proposed Fix above. + +## Test Strategy +Seeded from issue (corrected against research where noted): + +- [ ] `Merge-CoberturaClassesByFilename`: add a new `Get-CoberturaPackageLineSummary` helper and recompute/set `<package>`-level `line-rate`/`branch-rate` after class merges; union `<methods>` entries across the merged group instead of cloning only the primary class's; add a focused fixture where a later class-level entry has strictly higher hits than the first +- [ ] Invoke-MSTestWithCoverage.ps1 (`Invoke-MSTestWithCoverageMain`): add a .claude-path exclusion clause to the existing assembly-discovery `Where-Object` filter (discovery-filter change only, not a coverage threshold change) +- [ ] ClosureFilter.ps1: docstring-only clarifications — ratify the local-function exclusion policy as intentional (finding 5), and document the bare-name overload-collision limitation and its safe, under-exclusion failure direction (finding 6, corrected scope; re-keying by full member signature is infeasible per Root Cause Analysis above and is not proposed); no production behavior change +- [ ] Invoke-MSTest.ps1: extract the discovery block into a new `Get-MSTestAssemblyPathList` function wrapped in `@(...)` so a single-match result stays an array under `Set-StrictMode -Version Latest`; applies only to this script, since Invoke-MSTestWithCoverage.ps1's equivalent discovery block is already `@()`-wrapped and needs no change + +- Regression tests to add or update: + - tests/scripts/vscode/Invoke-MSTestWithCoverage.Helpers.Tests.ps1: new Describe block for `Get-CoberturaPackageLineSummary`; update the existing "preserves the primary class methods subtree and every hits value when merging" test's assertions (method count and members) to reflect the union-merge behavior — this is a deliberate, called-out assertion change per finding 2, not an unintended regression (see Risks & Mitigations below); add a new isolated 3-member merge fixture exercising the union/no-collision case; add one new minimal fixture isolating the max(hits) second-seen-strictly-higher branch (finding 4, test-only, no production change). + - tests/scripts/vscode/Invoke-MSTestWithCoverage.ClosureFilter.Tests.ps1: add one new pinning test documenting the finding-6 bare-name overload-collision, safe-direction behavior (one exempt overload, one non-exempt overload, same declaring type/file). + - tests/scripts/vscode/Invoke-MSTest.RunSettings.Tests.ps1: add a new Describe block for `Get-MSTestAssemblyPathList` with cases for zero matches, exactly one match (the StrictMode regression case for finding 7), and multiple matches; add a new It in the existing `Describe 'Invoke-MSTestWithCoverageMain'` block asserting a path under a .claude directory segment is excluded from the assembly list passed to coverage collection (finding 3). +- Unit tests (pytest) for the fixed behavior and boundaries: not applicable — this repository has no Python toolchain. All unit tests for this item are Pester tests under tests/scripts/vscode/, listed above. +- Edge cases and negative scenarios (invalid inputs, missing data, boundary values): zero-match and multiple-match discovery cases for `Get-MSTestAssemblyPathList` (finding 7); a merge group with three or more members contributing distinctly named methods (finding 2); a merge group where the second-seen class-level line entry has strictly higher hits than the first (finding 4); a same-name overload collision between an exempt and a non-exempt member (finding 6 pinning test). +- Error handling and logging verification: none of the seven findings introduces a new error path; no new error-handling test case is required beyond the existing coverage in the target test files. +- Coverage impact and targets for changed lines/modules: all seven findings are within scripts/vscode/, covered by Pester. Pester does not measure branch coverage, so only the line-coverage floor applies to these files per the repository's general unit-test policy; new and changed lines should meet the same line-coverage expectations the existing tests in these files already meet. No coverage threshold or CI gate is added, removed, or modified by this item; that ownership belongs to issues #561, #562, and #563. +- Toolchain commands to run (format → lint → type-check → test): format via the PoshQC format tool; lint via the PoshQC analyze tool; type-check is not applicable for PowerShell; test via the PoshQC Pester test tool using the repository's pester.runsettings.psd1 config. Run format, then lint, then test, in that order, restarting from format if any step fails or changes files. +- Manual validation steps (if required): none required beyond the automated Pester regression suite; these are internal developer-tooling scripts with no manual UI or runtime surface to validate. + + +## Acceptance Criteria +- [x] Repro steps now produce the expected behavior in all documented environments. +- [x] Regression test(s) added and passing (list file path and test name). +- [x] Edge cases and invalid inputs are handled with correct errors or fallbacks. +- [x] No unintended behavior changes outside the defined scope. +- [x] Required logs/telemetry updated and validated (if applicable). +- [x] Performance constraints met or explicitly waived with rationale. +- [x] Full toolchain pass completed (format → lint → type-check → test). +- [x] Docs/config references updated to match the new behavior. + +## Risks & Mitigations +- Technical or operational risks: + - Finding 2's fix changes the assertions of an existing, currently-passing Pester test — "preserves the primary class methods subtree and every hits value when merging" in tests/scripts/vscode/Invoke-MSTestWithCoverage.Helpers.Tests.ps1 — which currently locks in "do not merge methods" as an intentional prior decision (its own comment states this explicitly). The research concludes this prior test was pinning the defect described by finding 2, not a correct spec. This is called out here explicitly, per the instruction to treat existing unit tests as part of the spec, as a deliberate, spec-approved test-assertion change, not an unintended regression. + - Finding 2's union-append assumes no two group members legitimately share an identical method name within one merge group. If that assumption is wrong for some real-world compiler output, the union-append could double-count a method. Mitigation: verify with a 3+-way merge fixture during test authoring, as the research recommends, before relying on the no-dedup-key design in production. + - Finding 6's corrected scope leaves the underlying bare-name overload-collision limitation unresolved (it undercounts coverage for an exempt overload sharing a name with a non-exempt overload). Mitigation: this is accepted as the safe, under-exclusion failure direction per the function's own fail-safe invariant, and is now documented and pinned by a regression test so it cannot silently drift into the unsafe, over-exclusion direction. + - Finding 7's extraction (`Get-MSTestAssemblyPathList`) touches Invoke-MSTest.ps1's bare top-level script body, which has no existing wrapper-function pattern (unlike Invoke-MSTestWithCoverage.ps1). Mitigation: keep the extraction minimal and mirror the sibling script's naming and structure conventions exactly, as recommended by the research, to avoid a broader unplanned refactor. +- Mitigations and rollbacks: + - All seven fixes are small and independently revertible via a git revert of the specific file(s) touched. None of the fixes introduces a runtime feature flag or migration, so rollback carries no data or compatibility risk. + +## Rollout & Follow-up +- Release/rollout steps: standard PR merge to main after the full PowerShell toolchain (format, lint, test) passes; no staged rollout, feature flag, or environment-specific deployment is required for these developer-tooling script changes. +- Post-fix monitoring or clean-up tasks: none required.
