A repository-wide Grep for +`UiThreadDispatcherGate|SwapUiThreadDispatcher` restricted to `*.cs` returns zero files. + +The mechanism that exists today is `UiThreadDispatcherFixture` and `UiThreadDispatcherTransaction` in +`QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs`, whose own documentation +comment states it is the owner of every mutation of the process-wide static +`UtilitiesCS.UiThread._dispatcher` made from this test assembly's owned files, and that swaps are +serialized behind a `TransactionGate`. + +**CORRECTION, 2026-09-12T15-05.** An earlier revision of this artifact attributed that replacement to +issue #648. That was WRONG and is corrected here. The fixture's own doc comment at +`QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs:12-13` attributes the design +to **issue #493**, not #648. The error arose from inferring authorship from a `git log --grep=648` hit on +the merge commit of PR #719, branch `bug/wpfuidispatchertests-ungated-static-swap-648`; that change added +`WpfUiDispatcherTests` as a CONSUMER of the existing fixture rather than creating it. The delegated +researcher caught this independently and the doc comment was then re-read directly to confirm it. The +substantive point is unaffected: the lead's named symbols no longer exist, and the replacement predates +neither the measurement nor the lead in a way that rescues the lead. + +Consequence: the lead is stale as written. It must be re-tested against the current gate, not assumed. +The open question is whether #648 closed the contention or merely renamed and centralized it. + +## Finding 2 — the window-handle cause is already falsified, and #511/#571 already say so + +Acceptance criterion 5 asks that the closing comments of #511 and #571 be checked so they do not assert +the falsified window-handle cause without correction. Both issues carry two comments that already do this +explicitly, with identical text: + +- A "Premise correction from the epic execution run (2026-08-22)" comment stating the stated root cause is + falsified by measurement. +- A "Closing as superseded by #592" comment repeating the refutation with source citations. + +The refutation, as recorded there: + +- `ItemViewer()` calls `InitializeComponent()` at `QuickFiler/Viewers/ItemViewer.cs:25`. +- `InitializeComponent` runs `BeginInit()` on both WebView2 children at + `QuickFiler/Viewers/ItemViewer.Designer.cs:89-90` and `EndInit()` at `:6166-6167`. +- `EndInit` creates the child handles, and WinForms creates a parent's handle when a child's handle is + created, so the viewer's handle exists the instant construction returns. +- Forcing the handle is therefore a measured no-op. +- The failure signature is seven expiries at 60,000 ms, not an immediate exception; a missing handle makes + `Control.Invoke` throw at once rather than hang for sixty seconds. + +So AC5 is predominantly a verification rather than a repair. What does remain is a forward-pointer defect: +both closing comments direct the reader to #592 for the real defect, and #592 is now itself closed +NOT_PLANNED and consolidated into #743. Both comments also restate the stale gate hypothesis from Finding 1. + +## Finding 3 — measured base rate and the statistical bound + +Recorded in #592 and repeated in the #511 and #571 closing comments: + +- Pre-fix run-level failure rate approximately 1 in 21, that is approximately 4.8 percent. +- Thirty consecutive clean runs has probability approximately `0.952^30`, approximately 0.23, under the + null hypothesis of no effect. Thirty clean runs is therefore not sufficient evidence of efficacy. +- Under induced 17-node MSBuild contention a supplementary pass was 8 of 10 green. +- The one genuine pre-fix failure was seven expiries at the 60,000 ms `PumpTimeoutMs`. +- `PumpTimeoutMs = 60000` is cited at `QuickFiler.Test/Controllers/QfcItemController.InitializationTests.cs:38`. + +## Finding 4 — the contradiction between #511 and #571, and its bearing on the constraint set + +The closing comments record that #511 and #571 cannot both be implemented as written: #511 proposes +replacing the real message pump with an injectable context, which executed literally deletes the very +tests #571 exists to stabilize. This is the origin of the inherited constraint forbidding a fake +`SynchronizationContext` that replaces the real pump. That constraint remains in force for this delivery. + +The constraint that is deliberately re-opened for issue #743, and only for it, is the prohibition on +production edits. + +## Finding 5 — prior-art branch with unmerged evidence + +Evidence and a halted implementation are preserved unmerged on branch +`bug/winformspumphost-suite-determinism-511-exec` at commit `53a2a08f`, under +`docs/features/active/winformspumphost-suite-determinism-511/evidence/`, described as 36 markdown +evidence artifacts including `evidence/regression-testing/webview-child-handle-measurement.2026-08-21T18-10.md`. +That branch was not merged and no production file was modified on it. + +## Finding 6 — a second, independent failure mode recorded on #511 + +A #511 comment dated 2026-08-08 records that the two pump-hosted tests +`InitializeBool_ThroughThePumpHost_CompletesAndInitializesState` and +`InitializeNineArgOverload_ThroughThePumpHost_SavesParametersAndDelegates` failed with +`System.InvalidOperationException: Invoke or BeginInvoke cannot be called on a control until the window +handle has been created`, and that they pass in class isolation and in their own assembly but fail in the +combined instrumented nine-assembly run. That is an exception signature, not a timeout signature, and the +later 2026-08-22 premise correction concluded the handle attribution was falsified. Whether these are two +distinct failure modes or one misread observation is not resolved by the issue record and should not be +assumed either way. + +## Output Summary + +Four issues read. The maintainer's first lead is stale: its named symbols were refactored away by #648. +The window-handle cause is already falsified and both #511 and #571 already carry explicit corrections, so +AC5 reduces to a verification plus a forward-pointer update.

Conversely, extracting logic OUT of that excluded method into a covered member CHANGES the + denominator. Coverage can then move in either direction for reasons unrelated to test quality, so a + naive retained-or-improved comparison can produce a false failure or a false pass. + +The acceptance criterion must therefore be phrased against a named test and an explicitly stated +denominator, not against a bare per-file percentage. + +Separately, `QuickFiler/Viewers/ItemViewer.cs` line 20 carries a TYPE-level `[ExcludeFromCodeCoverage]`. +The whole `ItemViewer` type is invisible to coverage, so no acceptance criterion may be phrased over +ItemViewer coverage at all. + +## Incidental pre-existing defect + +`QuickFiler/Controllers/QfcItemController.ViewerSetup.cs` lines 36-37 contain a stale comment reading +"the `await _itemViewer.UiSyncContext` on line 55".

A new `ItemViewer` partial must follow that shape. + `` at line 400 is the plain shape. +- `QuickFiler.Test/QuickFiler.Test.csproj`. Test entries are the plain shape, for example + `` at line 194. + +## Addendum 2026-09-12T15-20 — reconciliation with the delegated research artifact + +Three points where the orchestrator's independent measurement and the research artifact differ or where +the research needs a refinement. All three were re-measured against the tree for this addendum. + +1. **Concrete-cast count.** The research artifact states 14 `(ItemViewer)_itemViewer` casts. A raw Grep + returns 19 occurrences across three files: `QfcItemController.EventWiring.cs` 6, + `QfcItemController.Initialization.cs` 8, `QfcItemController.ViewerSetup.cs` 5. The difference is + comment lines. In `QfcItemController.ViewerSetup.cs` the occurrence at line 39 is inside a comment + block, leaving 4 live casts in that file. Both figures are defensible; 14 is the live count and 19 the + raw occurrence count. A plan task that asserts a count must state which it means. + +2. **`GetAllChildren` has two call sites, not one.** The research cites + `QuickFiler/Controllers/QfcItemController.ViewerSetup.cs:288`. The same extension is also called at + `:234`. The declaration is `public static IEnumerable GetAllChildren(this Control root)` at + `UtilitiesCS/Extensions/WinFormsExtensions.cs:146`, with a second overload taking an exclusion list at + `:160`. Because it extends `System.Windows.Forms.Control` and `IItemViewer` does not derive from + `Control`, neither call site can be routed through the interface. The research finding is confirmed and + its blast radius is one site larger than stated. + +3. **File-length headroom confirmed exactly.** `QuickFiler/Controllers/QfcItemController.ViewerSetup.cs` + is 467 lines. The repository limit in `.claude/rules/general-code-change.md` is 500 lines for + production code, so there are 33 lines of headroom. This file is simultaneously the primary edit target + for this item and the declared edit target of a sibling item in the same parallel run, which makes it + the highest-risk file in the write set on both counts. A plan that adds more than 33 lines to it + violates the file-size rule and must extract to a new partial instead, which in turn requires a + `QuickFiler/QuickFiler.csproj` `Compile` entry. + +## Addendum 2026-09-12T15-45 — `ItemViewer.Designer.cs` initialization citations + +Verified directly against `QuickFiler/Viewers/ItemViewer.Designer.cs`: + +| Location | Content | +|---|---| +| `:46` | `this._l0vhBreadcrumb_WebView2 = new Microsoft.Web.WebView2.WinForms.WebView2();` | +| `:49` | `this._l0v2h2_WebView2 = new Microsoft.Web.WebView2.WinForms.WebView2();` | +| `:89` | `BeginInit()` on `_l0v2h2_WebView2` | +| `:90` | `BeginInit()` on `_l0vhBreadcrumb_WebView2` | +| `:92` | `BeginInit()` on `_topicThread` | +| `:6165` | `EndInit()` on `_l0v2h2_WebView2` | +| `:6166` | `EndInit()` on `_l0vhBreadcrumb_WebView2` | +| `:6169` | `EndInit()` on `_topicThread` | + +Two corrections follow. + +1. **The `EndInit` citation in the #511 and #571 closing comments is off by one line.** Both state + `:6166-6167`. The WebView2 `EndInit` pair is at `:6165-6166`. The substance of the premise correction + is unaffected, because the pair exists and does create the handles. The drift is worth noting only + because acceptance criterion 5 involves those comments, and a reconciliation that repeats a wrong line + number propagates it further. + +2. **A third control participates in the same initialization protocol.** `_topicThread` is begin-inited at + `:92` and end-inited at `:6169`. The issue record consistently describes the fixture cost as two + WebView2 children; there are three `ISupportInitialize` participants. This does not change the + direction of the finding, and the two WebView2 controls are very likely the dominant pair, but a plan + that asserts a count of initialized controls should say three rather than two, or should scope its + claim to WebView2 controls specifically. + +## Output Summary + +Two supplied paths were wrong and are corrected. Three of four supplied `ViewerSetup.cs` line numbers do +not resolve and the real marshalling sites are enumerated. The #729 counts of 4 declarations and 19 +usages both still hold. The controlling risk for acceptance criterion 4 is that the primary cited edit +site is already excluded from coverage measurement, which makes a bare per-file coverage criterion +unfalsifiable. diff --git a/docs/features/active/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam-743/evidence/other/orchestrator-constraint-conflict.2026-09-12T14-45.md b/docs/features/active/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam-743/evidence/other/orchestrator-constraint-conflict.2026-09-12T14-45.md new file mode 100644 index 000000000..5f4202570 --- /dev/null +++ b/docs/features/active/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam-743/evidence/other/orchestrator-constraint-conflict.2026-09-12T14-45.md @@ -0,0 +1,88 @@ +# Orchestrator Note: Constraint Conflict Requiring Explicit Resolution (Issue #743) + +Timestamp: 2026-09-12T14-45 +Collected by: orchestrator (preparation mode) +Method: Read of the cited #729 research artifact and of the inherited constraint set +EXIT_CODE: 0 + +## The conflict + +`CLAUDE.md` requires that conflicting instructions be surfaced rather than silently interpreted.

The +constraint is not arbitrary caution. It prevents the item from "fixing" the flake by removing the test +coverage that detects the underlying behavior, which would satisfy a green suite while losing the +guarantee. + +## Resolution + +The constraint set is explicit about which prohibition is lifted, so this resolves determinately rather +than requiring a maintainer decision: + +1. Production edits ARE permitted. The injectable seam may therefore be added to production code, which + is the substance of Source A's recommendation and the substance of this issue. +2. The seam MUST NOT be used to replace the real pump in the existing pump-hosted tests. Those tests stay + pump-hosted and keep exercising the real message loop. +3. The seam's legitimate purpose is to let members that do NOT require a real Win32 message loop be + tested without constructing the full pump fixture, which shortens the expensive path without deleting + the guarantee. + +So Source A's seam is adopted and Source A's final clause, "replace the message loop entirely", is +rejected. The word "entirely" is what fails; a partial, additive seam is permitted and is the intended +remedy. + +## What the spec must therefore state, explicitly and per test + +The spec cannot leave this implicit. For every test touched it must say which of two categories it falls +into: + +- **RETAINED pump-hosted.** Keeps `WinFormsPumpHost` and the real message loop. Its coverage contribution + is the thing the constraint protects. +- **MOVED to the seam.** Demonstrably does not depend on real Win32 handle creation or + `Control.BeginInvoke` marshalling, and therefore loses nothing by not running on the pump. + +A test may only be placed in the second category with a stated justification. Acceptance criterion 4, +retained-or-improved coverage of `QfcItemController.Initialization.cs` and `QfcItemController.ViewerSetup.cs`, +is the numeric check on that judgment, subject to the coverage-visibility caveat recorded in +`orchestrator-citation-verification.2026-09-12T13-50.md`. + +## A second, smaller conflict in the scaffolded spec + +The template `spec.md` that `new_active_feature_folder` generated carries the promoted record's +"Expected Behavior" prose, which reads: + +> ... either by scaling the harness bound to the environment or by allowing a synchronous fake to replace the real +> message pump for the members under test. + +Both of those alternatives are forbidden. Scaling the harness bound is a timing tolerance, and the second +clause is the Source A problem again.

A test blocked in +`TransactionGate.WaitAsync()` is spending its own timeout budget while waiting, even though it is doing +no work. With one permit, a serialized queue, and a per-holder cost dominated by a real WinForms control +tree with two WebView2 children, the waiting time for a test late in the queue scales with the number of +predecessors multiplied by the per-fixture cost. + +Under CPU contention every holder's cost rises, so the queue tail crosses 60,000 ms. That predicts +exactly what the record reports, and predicts it better than the falsified handle attribution does: + +- Expiry at the timeout bound rather than an exception, because waiting is not faulting. +- Several tests expiring together (the recorded genuine failure was seven expiries), because the whole + queue tail crosses the bound at once rather than one test failing independently. +- Load sensitivity, because contention inflates the per-holder cost that the queue multiplies. +- Passing in class isolation and in the assembly alone but failing in the combined instrumented + nine-assembly run, as recorded on #511 for 2026-08-08, because instrumentation overhead inflates the + same per-holder cost. + +## Counter-evidence that substantially weakens this hypothesis + +Added 2026-09-12T14-35, after the sections above were written. It is recorded here rather than silently +removing the hypothesis, because the plan must weigh both. + +A Grep for `Parallelize` over `QuickFiler.Test/**/*.cs` returns only two `[DoNotParallelize]` class +attributes, at `QuickFiler.Test/Helper Classes/ViewerQueueStaticWrapperTests.cs` line 11 and +`QuickFiler.Test/Helper Classes/EmailMoveMonitorTests.cs` line 24. There is no `[assembly: Parallelize]`, +which corroborates claim 3 of the #729 research: `QuickFiler.Test` runs serially under the MSTest default. + +If tests in the assembly never run concurrently, then no second test is ever waiting at +`TransactionGate.WaitAsync()` while a first holds it, and the queue-wait mechanism above cannot arise in +the ordinary case. The gate would always be free at acquisition. + +This does not reduce the hypothesis to zero, but it narrows it sharply. The residual ways it could still +bite are narrower and each must be measured rather than assumed: + +- A transaction released late, after its test has formally completed, so the NEXT test's acquisition + blocks on a predecessor the runner already considers finished. `BuildPumpHarnessAsync` holds until + `PumpHarness.Restore`, so a path that fails to restore promptly produces exactly this. +- A transaction leaked entirely by a faulted or timed-out test, after which every subsequent acquirer + blocks forever and expires at its own `[Timeout]`. This would produce a CLUSTER of expiries following + one initial failure, which matches the recorded signature of seven expiries better than an independent + per-test cost does. +- The `EnsureDispatcher` path at line 99 of the fixture, whose own doc comment states that disposing the + returned scope is optional and that "a discarded scope leaks exactly as the pre-fix helper did". + +The leaked-transaction variant is the most promising of the three and is the one worth instrumenting +first, because it explains clustering without requiring concurrency. + +The competing explanation remains the one the #729 research favours: the real elapsed cost of building a +WinForms control tree with two WebView2 children, inflated by coverage instrumentation and by CPU +contention from OTHER assemblies running in parallel in the combined nine-assembly run. Cross-assembly +parallelism does not contend on this static gate, which lives only in `QuickFiler.Test`, but it does +contend for CPU. + +Both explanations predict load sensitivity. They are distinguished by whether failures cluster after a +first failure (favouring the leak) or arrive independently (favouring elapsed cost). The recorded seven +simultaneous expiries is weak evidence for clustering, but it is a single observation. + +## Relationship to the maintainer's lead + +The lead is stale in its naming and understated in its scope, but it is not wrong in substance. Issue +**#493** did not remove the contention it describes; it centralized every swap behind one owner and, by +holding the gate across the full fixture build to preserve the #230 hold window, gave the serialized +region a longer critical section than the pre-#493 helper had. + +That is a hypothesis about a change in degree and it must be measured. It is entirely possible that #493 +reduced total contention by eliminating lock-ordering stalls even while lengthening the critical +section. Preparation mode cannot settle it. + +**CORRECTION, 2026-09-12T15-05.** An earlier revision of this artifact attributed the replacement to +issue #648 throughout. The correct attribution is **#493**, per the fixture's own doc comment at +`QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs:12-13`. Issue #648 only added +`WpfUiDispatcherTests` as a consumer of the already-existing fixture. The orchestrator's original +attribution was inferred from a commit-title grep rather than read from source, which is the error class +this repository's evidence rules exist to prevent. + +## Bearing on the fix + +If this mechanism is confirmed, an injectable UI-marshalling seam on `ItemViewer` addresses the defect by +removing the need to construct a real `ItemViewer` inside the serialized region for the tests that do not +require one, which shortens the critical section and shrinks the queue. That is a different remedy from +replacing the real message pump, so it does not violate the inherited constraint that forbids a fake +`SynchronizationContext` substituting for the real pump, and it does not introduce a timing tolerance. + +The plan must state which tests keep the real pump and which move to the seam, because the inherited +constraint exists precisely to stop the seam from deleting the coverage that the pump-hosted tests +provide. + +## Output Summary + +`TransactionGate` is a single-permit `SemaphoreSlim` awaited without timeout and held across the entire +pump-harness build and test body, and at least six test files acquire it rather than the two the +inherited lead names. However, `QuickFiler.Test` carries no `[assembly: Parallelize]` and runs serially, +so the simple queue-wait story cannot arise in the ordinary case. The surviving and most promising +variant is a LEAKED or late-released transaction, which would block every subsequent acquirer until its +own `[Timeout]` expires and would explain the recorded cluster of seven simultaneous expiries without +requiring concurrency. The competing explanation, favoured by the #729 research, is raw elapsed fixture +cost inflated by coverage instrumentation and by CPU contention from other assemblies. The two are +distinguished by whether failures cluster after a first failure or arrive independently. Nothing here was +measured at runtime; the plan must instrument to decide between them rather than adopt either. diff --git a/docs/features/active/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam-743/evidence/other/orchestrator-run-count-derivation.2026-09-12T14-15.md b/docs/features/active/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam-743/evidence/other/orchestrator-run-count-derivation.2026-09-12T14-15.md new file mode 100644 index 000000000..0a25ba38a --- /dev/null +++ b/docs/features/active/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam-743/evidence/other/orchestrator-run-count-derivation.2026-09-12T14-15.md @@ -0,0 +1,91 @@ +# Orchestrator Derivation: Sufficient Run Count (Issue #743, Acceptance Criterion 3) + +Timestamp: 2026-09-12T14-15 +Collected by: orchestrator (preparation mode) +Method: closed-form arithmetic over the base rate recorded in issues #592, #511 and #571 +EXIT_CODE: 0 + +## The recorded figures + +- Pre-fix run-level failure rate: approximately 1 in 21, that is approximately 4.8 percent. +- The issue record asserts that thirty consecutive clean runs has probability approximately `0.952^30`, + approximately 0.23, under the null hypothesis of no effect. + +## Verification of the recorded figure + +Let `q` be the per-run pass probability under the null, `q = 1 - 0.048 = 0.952`. + +`ln(0.952) = -0.0491903` +`30 * (-0.0491903) = -1.4757` +`exp(-1.4757) = 0.2286` + +So `0.952^30 = 0.229`, which rounds to the 0.23 the issue record states.

This finding was previously tracked standalone as issue #711, closed 2026-09-02 as "superseded by consolidated issue #729"; #729's research concluded finding 4 cannot be closed deterministically within that item and must be re-promoted here so it is not silently dropped a second time. + +## Environment + +- OS/version: Windows 11 Pro (repo default) +- Python version: n/a — C# MSTest suite +- Command/flags used: `vstest.console.exe` over discovered `*.Test.dll` with `/EnableCodeCoverage /InIsolation /TestCaseFilter:TestCategory!=LiveOutlook` +- Data source or fixture: `QuickFiler.Test` pump-host and dispatcher fixtures (`QfcItemController.InitializationTests*.cs`, `.SeamFactoryTests.cs`, `.ViewerSetupTests.cs`, `WebView2BreadcrumbHostTests.cs`) + +## Steps to Reproduce + +1. Run the full discovered `QuickFiler.Test` set with `/EnableCodeCoverage` while the machine is under concurrent load. +2. Observe pump-hosted `QfcItemController`/`WebView2BreadcrumbHost` tests fail at approximately 60 seconds each. +3. Re-run the same command against a byte-identical tree with the machine idle. +4. Observe the same tests pass. + +## Expected Behavior + +Per `.claude/rules/general-unit-test.md`'s Determinism Infrastructure section, test outcomes must not depend on host load. Pump-hosted `QfcItemController`/`WebView2BreadcrumbHost` tests should complete deterministically regardless of CPU contention, either by scaling the harness bound to the environment or by allowing a synchronous fake to replace the real message pump for the members under test. + +## Actual Behavior + +Research performed under issue #729 (2026-09-02) confirmed: `PumpTimeoutMs` (declared 4 times across `QfcItemController.InitializationTests.cs:38`, `.SeamFactoryTests.cs:327`, `.ViewerSetupTests.cs:34`, `WebView2BreadcrumbHostTests.cs:25`) is used in exactly 19 places, all as the argument of an MSTest `[Timeout(...)]` attribute, and never as a wait/poll duration — the test logic itself contains no `Thread.Sleep`, `Task.Delay`, `Stopwatch`, or polling loop. The load-sensitivity is not a test-determinism defect in the MSTest-visible sense; it is that the *real elapsed cost* of constructing the production object graph under test can exceed the 60-second harness bound under contention. + +No test-only fix removes this, for four reasons documented in the #729 research artifact (`docs/features/active/2026-09-02-test-determinism-and-hygiene-debt-729/research/research-729.2026-09-02T09-30.md`, section 4.2): + +1. `QuickFiler/Viewers/ItemViewer.cs:23-29` reads `SynchronizationContext.Current` and `Dispatcher.CurrentDispatcher` directly at construction (`_context = SynchronizationContext.Current;`), with no injectable seam; `UiSyncContext` (`ItemViewer.cs:59-62`, `IItemViewer.cs:37`) exposes it read-only. `QfcItemController.ViewerSetup.cs:64,320,331,336` await it directly. +2. The dominant fixture cost is a real WinForms control tree plus two handle-created `WebView2` children (`QfcItemController.InitializationTests.Part2.cs:74-84`), which only a real Win32 message loop can service — a fake `SynchronizationContext` cannot substitute for `Control.Handle`/`BeginInvoke` marshalling. +3. `[DoNotParallelize]` would be a no-op: `QuickFiler.Test` already runs serially (no `[assembly: Parallelize]`, CI passes no `/Settings:`). +4. Removing `[Timeout]` would trade a bounded, diagnosable failure for an unbounded CI hang on a genuine deadlock (documented rationale at `QfcItemController.InitializationTests.cs:33-37`). + +## Logs / Screenshots + +- [ ] Attached minimal logs or screenshot +- Snippet: each failure is recorded with an elapsed time of approximately 60 seconds and a `[Timeout]` message rather than an assertion-failure message, consistent with issue #711's original report. + +## Impact / Severity + +- [ ] Blocker +- [ ] High +- [x] Medium +- [ ] Low + +Medium: no incorrect production behavior; test-suite reliability/determinism debt that risks intermittent CI failures on a coverage-enabled or loaded runner, consistent with the closed #711 report this issue re-promotes. + +## Suspected Cause / Notes + +Root cause: `QuickFiler/Viewers/ItemViewer.cs` and the `QfcItemController` members it backs have no injectable UI-marshalling abstraction (an `IUiDispatcher`/`SynchronizationContext` seam, or an interface over the `WebView2` control accepted by `WebView2BreadcrumbHost`'s constructor). Until such a seam exists, the pump-hosted tests must construct real WinForms/WebView2 objects and are therefore coupled to real message-pump timing. This is a `QuickFiler/` production-code change, which was out of scope for issue #729 (test-only item; `QuickFiler/` production sources are owned by a different parallel work item in that run). + +## Proposed Fix / Validation Ideas + +- [ ] Give `QfcItemController`/`ItemViewer` an injectable `IUiDispatcher` (or equivalent `SynchronizationContext` provider) seam so tests can substitute a synchronous fake instead of relying on a live message pump. +- [ ] Introduce an interface over the `WebView2` control that `WebView2BreadcrumbHost` accepts via constructor injection, so its handle-creation cost is not incurred in pump-hosted unit tests. +- [ ] Once a seam exists, re-evaluate whether `PumpTimeoutMs = 60000` can be lowered, since the remaining wait would then be a controllable fake rather than a real Win32 message loop. +- [ ] Do not remove `[Timeout(PumpTimeoutMs)]` outright; it is a documented deadlock guard, not the load-sensitivity source. + +## Consolidation Note (2026-09-11): carries #592 + +Mirrored from the GitHub consolidation comment on issue #743, retrieved 2026-09-12. This section is +provenance. The authoritative acceptance-criteria source for this `full-bug` feature is `spec.md`, per +the `acceptance-criteria-tracking` skill. + +Issue #592 is closed as a duplicate root cause of this issue. Its acceptance criteria are carried here +and apply to this delivery in addition to the criteria above: + +- The mechanism producing the 60,000 ms expiry is identified and recorded with evidence, not inferred. + First lead to instrument: the `UiThreadDispatcherGate` / `SwapUiThreadDispatcher` contention between + `QfcItemController.SeamFactoryTests` and `QfcItemController.InitializationTests`, which mutate the + process-wide static `UtilitiesCS.UiThread._dispatcher` by reflection. +- A regression test reproduces the failure deterministically, without a sleep, a retry, or a timing + tolerance. +- The fix is demonstrated effective against the reproduction with a run count sufficient to distinguish + it from the roughly 4.8% base rate (thirty clean runs alone is not sufficient; p is approximately 0.23 + under the null). +- Coverage of `QuickFiler/Controllers/QfcItemController.Initialization.cs` and + `QfcItemController.ViewerSetup.cs` is retained or improved. +- #511 and #571 are reconciled against the corrected root cause (they are already closed; confirm their + closing comments do not assert the falsified window-handle cause without correction). + +Constraint note carried from #592: the `quickfiler-suite-determinism-foundation` epic forbade production +edits, timing tolerances, and a synchronization-context seam. This delivery deliberately re-opens the +production-edit constraint, as #743 requires; the other two remain in force. + +## Orchestrator Verification Note (2026-09-12) + +Two corrections to the text above were established before planning began. Both are recorded in +`evidence/other/issue-reconciliation-and-gh-context.2026-09-12T13-40.md`. + +1. The first lead is stale. `UiThreadDispatcherGate` and `SwapUiThreadDispatcher` exist in no `.cs` file + in the current tree; they were replaced by `UiThreadDispatcherFixture` and + `UiThreadDispatcherTransaction` under issue #493, per the fixture doc comment at + `QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs:12-13`. Issue #648 only + added `WpfUiDispatcherTests` as a consumer of that fixture. The replacement changed the owner of the + contention, not its shape: `TransactionGate` is still a one-permit `SemaphoreSlim` held from + acquisition to disposal. The lead must be re-tested against the current gate, not assumed. +2. The closing comments of #511 and #571 already carry an explicit premise correction refuting the + window-handle cause. The residual reconciliation work is a forward-pointer update, because both point + to #592, which is now itself closed and consolidated into #743. + +## Next Step + +- [x] Promote to GitHub issue (bug-report template) — issue #743 opened 2026-09-02 +- [x] Move to active fix folder / branch — active folder created 2026-09-12 diff --git a/docs/features/active/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam-743/plan.2026-09-12T13-23.md b/docs/features/active/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam-743/plan.2026-09-12T13-23.md new file mode 100644 index 000000000..dc8d4532a --- /dev/null +++ b/docs/features/active/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam-743/plan.2026-09-12T13-23.md @@ -0,0 +1,328 @@ +# 2026-09-02-quickfiler-itemviewer-ui-marshalling-seam (Plan) + +- **Issue:** #743 +- **Work Mode:** full-bug +- **Complexity:** C4 +- **Parent (optional):** none (consolidates closed #592, which superseded #511 and #571) +- **Owner:** drmoisan +- **Last Updated:** 2026-09-12T13-23 +- **Status:** Ready for preflight +- **Version:** 1.0 +- **Requirements source:** `docs/features/active/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam-743/spec.md`, section `## Acceptance Criteria`.

Every raw tool artifact this plan produces is written under the repository-root `coverage` directory, which `.gitignore` line 144 ignores with the pattern `coverage/*` (line 145 re-includes only `coverage/.gitkeep`). Numeric figures are transcribed into Markdown evidence artifacts and the raw output is then discarded. Note that `*.trx` is **not** gitignored anywhere in this repository, so writing a TRX anywhere other than under the ignored `coverage` directory would leave an untracked raw artifact and violate D1. + +**D2 — Evidence location is non-overridable.** Every evidence artifact resolves under `docs/features/active/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam-743/evidence//` with `` in {baseline, regression-testing, qa-gates, issue-updates, other}. No artifact is written to `artifacts/baselines`, `artifacts/qa`, `artifacts/coverage`, or any other non-canonical location. + +**D3 — Two execution regimes, named in every run-bearing task.** The repository root runsettings file declares `0` and `ClassLevel` (lines 5 and 6). The CI command at line 99 of the MSTest coverage workflow passes **no** `/Settings:` argument, so CI runs the assembly **serially**. `QuickFiler.Test` declares no `[assembly: Parallelize]`. + +- **SERIAL regime** = a `vstest.console.exe` invocation with **no** `/Settings:` argument. This is CI's regime. Gate contention cannot arise; elapsed fixture cost is the only available mechanism. +- **PARALLEL regime** = a `vstest.console.exe` invocation **with** `/Settings:TaskMaster.runsettings`. Distinct `[TestClass]` types run concurrently and the one-permit `TransactionGate` genuinely serializes them. + +Additionally verified this pass and load-bearing: `scripts/vscode/TaskMaster.cli.runsettings` **also** declares `0` and `ClassLevel`, and `scripts/vscode/Invoke-MSTestWithCoverage.ps1` line 76 always appends `/Settings:$RunSettingsPath` resolved to that file. **The repository coverage runner is therefore a PARALLEL-regime command.** Every coverage task below states this. + +**D4 — Part A is narrowed to exactly one converted site, with the reason recorded.** Spec section 6.2 names lines 282, 287, 298, 303 and 371 of `QuickFiler/Controllers/QfcItemController.ViewerSetup.cs`. The binding Write Set in the spec's `## Write Set` section admits seven paths and no others. Re-derived against the tree on 2026-09-12: + +- **Line 371 IS converted.** It is `await _itemViewer.UiDispatcher.InvokeAsync(...)`, a controller-performed marshal with a delegate argument. The production default seam is constructed at line 391 of the Initialization controller partial as `new UtilitiesCS.Threading.WpfUiDispatcher()`, whose parameterless constructor resolves its dispatcher lazily through `() => UiThread.Dispatcher` (lines 24-25 and 33-37 of `UtilitiesCS/Threading/WpfUiDispatcher.cs`) and whose `InvokeAsync(Action)` forwards 1:1 to `Dispatcher.InvokeAsync(action).Task` (line 43). This is the same primitive with the same delegate and the same queue, so the substitution is like-for-like and net zero lines. +- **Lines 282, 298 and 303 are NOT converted.** Each passes `_itemViewer.UiSyncContext` as the second **argument** of `QfcTipsDetails.CreateAsync(Label, SynchronizationContext, CancellationToken)`, declared at line 80 of the UtilitiesCS tooltips helper file. That file is in the `UtilitiesCS` project and is not in the binding Write Set. Converting these sites would require changing a public UtilitiesCS API signature, which is out of scope. They are argument-passing sites, not marshals the controller performs. +- **Line 287 is NOT converted.** It is `await itemViewer.UiSyncContext;`, a context **hop** after which every subsequent statement runs on the UI thread. The injected seam interface declares only `Invoke(Action)`, `InvokeAsync(Action)`, `InvokeAsync(Action, DispatcherPriority, CancellationToken)`, `BeginInvoke(Action)`, `InvokeAsync(Func)` and `InvokeAsync(Func>)` (lines 15 to 42 of `UtilitiesCS/Threading/IUiDispatcher.cs`). None of these is a hop. An equivalent conversion requires wrapping lines 288 through 328 inside a delegate, which is a restructure of a file with 33 lines of headroom that a sibling item is concurrently editing. Spec section 6.2 requires ordering equivalence to be **established before** the edit; it cannot be established for this site within the Write Set, so the site is deferred with this reason recorded. +- **Line 64 is NOT converted.** Spec section 6.2 already defers it: it sits inside a method carrying `[System.Diagnostics.CodeAnalysis.ExcludeFromCodeCoverage]` at line 47, whose residual barrier is a real WebView2 runtime. + +**D5 — Part B is the substantive fix and is what removes the construction cost.** `ResolveControlGroupsAsync` is widened from the concrete viewer type to the viewer interface. Two additive interface members replace the two concrete-only reads in its body. Re-derived: the descendant enumeration at line 288 is an extension method on `System.Windows.Forms.Control`, declared at line 146 of `UtilitiesCS/Extensions/WinFormsExtensions.cs` in namespace `UtilitiesCS`, and the interface does not derive from `Control`; the item-number label read at line 281 reaches a concrete member the interface does not publish. + +**D6 — The additive members are `DescendantControls()` and `ItemNumberLabel`.** A repository-wide Grep over `*.cs` for either identifier returns **zero** matches as of 2026-09-12, so both names are free and a post-change occurrence count is falsifiable. Neither removes, renames nor narrows `UiDispatcher` or `UiSyncContext`, so the reflection contract tests at lines 248 and 264 of the breadcrumb drop-down contract test file continue to pass. + +**D7 — The fail-before is a runnable, defect-preserving seam, not a compile error.** Phase 2 widens the signature while deliberately retaining the concrete dependency as two explicit casts of the form `(ItemViewer)itemViewer`. A Moq proxy for the viewer interface does not derive from the concrete viewer class, so those casts throw `InvalidCastException` deterministically, with no timing dependency. Phase 3 replaces the casts with the additive interface members and the same tests pass. This preserves the exact pre-change defect ("the member cannot be driven without a concrete viewer") while making it observable from a test. + +**D8 — The seam tests install an ambient `SynchronizationContext`.** The awaiter extension `GetAwaiter(this SynchronizationContext)` is declared at line 198 of `UtilitiesCS/Threading/UiThread.cs`; its `IsCompleted` returns true at line 162 when the awaited context is reference-equal to the ambient context. The seam tests therefore install the same context instance the viewer mock returns as `SynchronizationContext.Current` for the duration of the test and restore the previous value in a `finally`, exactly as the existing headless viewer-setup test does at its lines 391-392 and 412. With that arrangement every `await ` in the call graph completes inline and **no message pump is required**. This is permitted: spec non-goal 2 bars replacing the real pump in the existing pump-hosted tests, and the seam-design-constraints artifact states explicitly that a context double in a test that never used the pump is not barred. No existing pump-hosted test is modified by this plan. + +**D9 — No new measurable production lines are added outside the edited controller partial.** The two additive interface members have no bodies. Their implementations live on the concrete viewer type, which carries a type-level `[ExcludeFromCodeCoverage]` at line 20 of `QuickFiler/Viewers/ItemViewer.cs` and therefore emits no Cobertura element at all. That exclusion is pre-existing; this item neither adds nor removes it. The repository's >= 90% new-code floor is therefore applied to the changed lines in `QuickFiler/Controllers/QfcItemController.ViewerSetup.cs` only, and no acceptance condition in this plan is phrased over concrete-viewer coverage. + +**D10 — Self-anchored diff base.** Phase 0 writes the ref `refs/plan/issue-743-base` at the current `HEAD`. Every `git diff` in this plan uses that ref as its explicit operand. No SHA is pinned in this plan text. + +**D11 — `.claude/agent-memory` is a tracked path in this repository and the executing agent writes to it during the run.** Every `git status`, `git diff` and `git ls-files` gate below is scoped with an explicit pathspec so that agent-memory writes cannot satisfy or falsify it. + +--- + +## Write Set (binding;

They were removed by issue #493 and replaced by `UiThreadDispatcherFixture` / `UiThreadDispatcherTransaction`. | Maintainer's lead **falsified as literally stated** | +| F2 | The surviving `TransactionGate` **does** serialize, and blocking on it **does** burn the blocked test's own `[Timeout]` budget. Measured at ≈4.1 s of pure blocking in a committed TRX. | Mechanism **real but small** | +| F3 | Gate contention cannot be the dominant cause: **9 of the 19** `[Timeout(PumpTimeoutMs)]` tests never touch the gate, and 8 of those 9 are the `WebView2BreadcrumbHostTests` that #743 names in its own summary. | Lead **refined, not confirmed** | +| F4 | Gate contention requires class-level parallelization. CI passes **no** `/Settings:`, the assembly declares no `[assembly: Parallelize]`, and #743's own stated repro command passes no `/Settings:` either. | Lead **inapplicable under #743's stated repro** | +| F5 | The strongest surviving form of the lead is a **gate leak, not gate contention**: MSTest's default non-cooperative `[Timeout]` stops observing a timed-out method, so a gate-holding test that expires may never run its `finally`. `#511 spec.md:132-139` already recorded exactly this and left it unfixed. | **Open, untested, worth an AC** | +| F6 | The dominant cost is the real `ItemViewer` construction: `ItemViewer.Designer.cs` is **6223 lines** and `InitializeComponent` instantiates 110 controls including two `WebView2` children whose `EndInit` creates the handles. First-in-class pump tests measure 3.3 s and 6.2 s on an idle 24-worker box; siblings measure 0.18–0.43 s. | **Confirmed (b)** | +| F7 | An `IUiDispatcher`-style marshalling seam **alone does not remove that cost**, because `QfcItemController` reaches the viewer through 14 `(ItemViewer)_itemViewer` concrete casts and one `ResolveControlGroupsAsync(ItemViewer)` signature. | **Central design constraint** | +| F8 | `QuickFiler/Interfaces/IItemViewer.cs` does not exist. The file is `QuickFiler/Viewers/IItemViewer.cs`. | Citation **corrected** | +| F9 | `QuickFiler/Viewers/ItemViewer.cs:20` carries `[ExcludeFromCodeCoverage]`, and the type is therefore **absent** from committed Cobertura, not reported at 0%. | **Confirmed** | +| F10 | The #729 census of `PumpTimeoutMs` (4 declarations, 19 usages, all `[Timeout]`) **still holds exactly**, at the same line numbers. | **Re-derived, unchanged** | +| F11 | The AC-3 arithmetic checks out: 0.952381^30 = 0.2314.

Under those conditions MSTest runs the assembly +serially and the gate is never contended. Note the discrepancy: **#711's** repro command +(`.../2026-08-31-quickfiler-pump-host-tests-load-sensitive-under-coverage.md:20`) *did* include +`/Settings:TaskMaster.runsettings`, and `TaskMaster.runsettings:4-7` declares +`0ClassLevel`. The two repro commands are not the same experiment. + +**(c) The measured magnitude is an order of magnitude too small.** See §4.2: ≈4.1 s of blocking +against a 60,000 ms bound. + +### 2.5 The surviving, untested form of the lead: a leak, not contention + +`docs/features/active/2026-08-21-winformspumphost-suite-determinism-511/spec.md:132-139` states it +precisely, and explicitly leaves it unfixed: + +> "**The MSTest `[Timeout]` / `UiThreadDispatcherGate` cascade is not fixed here.** The research +> identifies a second, independent load amplifier: MSTest's `[Timeout]` on a `Task`-returning test +> records a failure without aborting the continuation, so a timed-out pump test has not yet run its +> `finally` and therefore has not released the process-wide `UiThreadDispatcherGate` semaphore or +> reverted `UtilitiesCS.UiThread._dispatcher`." + +That statement survives #493 verbatim with `TransactionGate` substituted for `UiThreadDispatcherGate`, +because the release still happens only inside the test's `finally` +(`QfcItemController.InitializationTests.Part3.cs:63-71` → `harness.Restore()` → +`Part2.cs:317-330` → `_transaction.Dispose()` → `UiThreadDispatcherFixture.cs:275`). + +The authoritative MSTest semantics are given in §5.2.

Design options for the seam + +### 7.1 The inherited constraints, restated exactly + +1. **No timing tolerance.** `.claude/rules/csharp.md` (cited at `epic.md:117`) prohibits "adding + sleeps, retries, or timing hacks to mask flaky behavior". This rules out raising `PumpTimeoutMs`, + scaling it by core count, adding retries, or `[Ignore]`. +2. **No fake `SynchronizationContext` replacing the real message pump.** Recorded as an explicit + non-goal at `#511 spec.md:121-123` and `epic.md:78-79`. +3. **Coverage of the de-exempted members must not be lost.** `#511 spec.md:265-267`: "Every one of + the eight pump-hosted consumer tests is the named coverage evidence for at least one de-exempted + production member. Deleting, `[Ignore]`-ing, or reclassifying any of them out of the unit suite + invalidates the corresponding comment and re-opens the exemption question." The affected + justification blocks are `QfcItemController.Initialization.cs` at 135, 164, 196, 259, 291, 403, + 447 and `QfcItemController.ViewerSetup.cs` at 254 (`#511 spec.md:246-258`; those line numbers are + themselves pre-drift and must be re-derived before use). +4. Production edits **are** permitted for this item. + +Constraint 2 is the one that most constrains the design. It does **not** prohibit an injected +*marshalling abstraction* — `UtilitiesCS.Threading.IUiDispatcher` already exists, is already a +production constructor parameter, and is already mocked by these very tests. It prohibits +substituting a counterfeit `SynchronizationContext` for the Win32 loop. + +### 7.2 The production surface that bypasses the existing seam + +`QfcItemController` marshals through **three** distinct channels. Only the first is injectable. + +| Channel | Type | Sites | +|---|---|---| +| `IUiDispatcher _uiDispatcher` | `UtilitiesCS.Threading.IUiDispatcher` (`QfcItemController.cs:66`) | ~20 sites; injected at `Initialization.cs:59`, `:438`, `:480`; defaulted `??= new WpfUiDispatcher()` at `:391` | +| `_itemViewer.UiSyncContext` | raw `SynchronizationContext` | `ViewerSetup.cs:64, 282, 287, 298, 303` — **5** | +| `_itemViewer.UiDispatcher` | raw WPF `Dispatcher` | `Initialization.cs:200`, `FolderHandling.cs:188`, `ViewerSetup.cs:371` — **3** | + +**8 production sites in `QfcItemController` bypass the existing seam.** That is the precise surface +#743 is about. (`EfcItemController.cs:191, 846, 855, 1104` have the same shape but are a different +controller and out of scope.) + +### 7.3 The blocker that no marshalling seam removes + +`QfcItemController` reaches the viewer through **14** `(ItemViewer)_itemViewer` concrete casts plus +one concrete signature: + +- `Initialization.cs:179, 184, 216, 220, 274, 279, 308, 312` +- `EventWiring.cs:37, 50, 313, 318, 327, 332` +- `ViewerSetup.cs:75, 85, 114` (inside the already-exempt `InitializeWebViewAsync`) +- `ViewerSetup.cs:276` — `internal async Task ResolveControlGroupsAsync(ItemViewer itemViewer)` + +and at `ViewerSetup.cs:288` it calls `itemViewer.GetAllChildren()`, which is an **extension method on +`System.Windows.Forms.Control`** (`UtilitiesCS/Extensions/WinFormsExtensions.cs:146`) and therefore +**cannot be invoked through `IItemViewer`** without a new intent member on the interface. + +**Therefore: making the marshalling injectable does not make the tests cheap.** As long as those +casts stand, every test of those members must construct a real 6223-line `ItemViewer`. This is the +single most important design conclusion in this artifact. + +### 7.4 Recommended approach + +**Two-part, sequenced. Part A is the #743 deliverable; Part B is what actually removes the 60 s risk +and should be scoped explicitly rather than assumed.** + +**Part A — route the 8 bypassing sites through the existing `IUiDispatcher` seam.** + +Replace each `await _itemViewer.UiSyncContext` with an `_uiDispatcher`-mediated marshal, and each +`_itemViewer.UiDispatcher.InvokeAsync(...)` with `_uiDispatcher.InvokeAsync(...)`. No new abstraction +is introduced; the seam already exists, is already production-default-wired (`Initialization.cs:391`), +and already has a synchronous test double (`QfcItemControllerTestSupport.BuildSyncDispatcher()` at +`QuickFiler.Test/Controllers/QfcItemController.TestSupport.cs:105-145`). + +*Why this satisfies constraint 2:* the substitute is an `IUiDispatcher`, not a counterfeit +`SynchronizationContext`.

The interface-widening precedent is already established in +this exact file: `IItemViewer.cs:39-52` carries display-state intent members added for the same +reason, and `:184-194` re-declares `InvokeRequired`/`Invoke`/`BeginInvoke` with the in-file rationale +"declared on the interface (not resolved by a concrete cast) so InvokeRequired-guarded [callers stay +mockable]". + +*Effect:* the member becomes coverable against a `Mock` plus a handful of real `Label`s +on a bare `UserControl` — a control tree three orders of magnitude smaller than the Designer's — +while **the same production member keeps the same coverage**, satisfying constraint 3.

Issue #592 was closed as a duplicate root cause on +2026-09-11 (state reason NOT_PLANNED) and its acceptance criteria are carried into the Acceptance +Criteria section of this spec. #511 and #571 were previously closed as superseded by #592. + +This spec replaces the auto-generated template that mapped the promoted record's prose. Two sentences +from that template were removed rather than carried forward, because both name remedies this item +forbids: "scaling the harness bound to the environment" is a timing tolerance, and "allowing a +synchronous fake to replace the real message pump" is the prohibition recorded in section 5. + +--- + +## 2. Corrections to the inherited record (established before planning) + +These four corrections are load-bearing. Planning and execution must use them in preference to the +prose they correct. + +**C1 — the maintainer's first lead is falsified as literally stated.** The identifiers +`UiThreadDispatcherGate` and `SwapUiThreadDispatcher` exist in **zero** `.cs` files in the current +tree. A repository-wide search restricted to `*.cs` returns no files; the surviving references are in +the docs tree and agent memory only, and the most recent code-bearing reference is the record of their +*removal* under issue #493. The mechanism that exists today is `UiThreadDispatcherFixture` / +`UiThreadDispatcherTransaction`, whose own doc comment at lines 12-13 of +QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs attributes the design to +issue #493. Issue #648 only added a consumer. Any acceptance criterion, plan task, or evidence +artifact that identifies the mechanism by the two removed names is invalid on its face. + +**C2 — #493 changed the owner of the serialization, not its shape.** `TransactionGate` is still a +one-permit `SemaphoreSlim(1,1)`, still awaited without timeout or cancellation token, and still held +from acquisition to disposal. The lead must therefore be re-tested against the current gate, not +assumed closed and not assumed open. + +**C3 — three of the four supplied `ViewerSetup.cs` citations do not resolve.** Lines 320, 331 and 336 +carry no marshalling site. The actual sites in `QuickFiler/Controllers/QfcItemController.ViewerSetup.cs` +are lines 64, 282, 287, 298 and 303 (synchronization-context path) and line 371 (WPF dispatcher path). +Lines 36, 273 and 365 are comment references, not executable sites. Line 64 is inside a method that is +excluded from coverage measurement; see C4. + +**C4 — two coverage exclusions make the naive form of criterion 4 unfalsifiable.** +`QuickFiler/Controllers/QfcItemController.ViewerSetup.cs` line 47 carries +`[System.Diagnostics.CodeAnalysis.ExcludeFromCodeCoverage]` on `InitializeWebViewAsync`, declared at +line 48, and the primary cited edit site at line 64 is inside that method. An edit confined to that +method produces no coverage delta at all. Separately, `QuickFiler/Viewers/ItemViewer.cs` line 20 +carries a **type-level** `[ExcludeFromCodeCoverage]`, so the whole `ItemViewer` type — including its +6,223-line Designer partial — emits no Cobertura `` element whatsoever and is unmeasurable, not +0 %. No acceptance criterion may be phrased over `ItemViewer` coverage, and no acceptance criterion may +be phrased as a bare per-file percentage over the two controller partials without a stated denominator. + +--- + +## 3. Reproduction and measured evidence + +### 3.1 Reported reproduction + +1. Run the full discovered `QuickFiler.Test` set with `/EnableCodeCoverage` while the machine is under + concurrent load. +2. Observe pump-hosted controller and breadcrumb-host tests fail at approximately 60 seconds each, with + a `[Timeout]` message rather than an assertion-failure message. +3. Re-run the same command against a byte-identical tree with the machine idle. +4. Observe the same tests pass. + +Note a discrepancy that changes which hypothesis a run tests: #743's stated command passes no +`/Settings:`, and CI passes no `/Settings:` either, so MSTest runs the assembly serially. #711's +original command *did* pass `/Settings:TaskMaster.runsettings`, which declares `0` +and `ClassLevel`. The two commands are not the same experiment. The plan must state +which one it runs, per run. + +### 3.2 What is measured and what is not + +| Figure | Value | Source quality | +|---|---|---| +| `PumpTimeoutMs` census | 4 declarations, 19 usages, all `[Timeout(...)]` arguments, 0 in a wait or poll position | Re-derived twice on 2026-09-12, unchanged from the #729 census, same line numbers | +| Gate-taking population | 21 test methods in 6 `[TestClass]` types contend for the single `TransactionGate` permit | Two independent censuses, acquire-side and release-side, agreeing member for member | +| Bypassing production sites | 8 sites in the `QfcItemController` partial read a marshalling primitive off the viewer instead of the injected seam (5 `UiSyncContext`, 3 `UiDispatcher`) | Usage census cross-checked against the interface's published marshalling surface | +| Measured gate blocking | approximately 4.10 s, i.e. 6.8 % of the 60,000 ms bound | Committed TRX timestamps, class-parallel idle run | +| Measured pump-test cost | first test in a class 3.3 s to 6.2 s; siblings 0.19 s to 1.04 s | Two committed TRX files, both idle, both 24-worker class-parallel | +| Measured load multiplier | 6x to 26x unloaded duration under sustained CPU saturation | Ten-run #511 determinism evidence | +| Pre-fix run-level failure rate | approximately 1 in 21, approximately 4.8 % | **Point estimate from a single observed failing run.** Exact 95 % interval for 1 of 21 is approximately [0.0012, 0.2382] | + +Applying the upper measured multiplier to the largest measured pump test gives 26 x 6.223 s, or +approximately 162 s, which exceeds the 60,000 ms bound; the lower multiplier gives approximately 37 s, +which does not. The bound therefore sits **inside** the measured load-multiplier band, which is the +signature of an intermittent load-correlated expiry. This is stated no more strongly than that: the +multiplier was measured suite-wide, not per test. + +### 3.3 Recorded unknowns, carried forward unresolved + +These are not to be resolved by assertion in the plan or in any evidence artifact. + +- **U1.** The identity of the seven tests that expired in the one recorded genuine failure is + **unrecoverable**. The underlying TRX is not in this worktree; #511 never merged, and its work is + preserved unmerged on branch bug/winformspumphost-suite-determinism-511-exec at commit 53a2a08f. + A repository-wide search of the docs tree for timeout signatures returns zero matches, so **there is no + committed artifact of an actual expiry anywhere in this tree.** +- **U2.** Whether the gate leak described in section 4.2 has ever actually occurred is **unknown and + untested**. Weak counter-evidence exists (no CI hang of the predicted shape has been reported, and + four gate-taking tests carry no `[Timeout]` at all, so a leak should hang one of them under CI's + serial ordering), but ordering is not pinned and this is not proof. +- **U3.** #711 reported fourteen failing tests; #511 recorded seven expiries. These are two + observations on two different days under two different commands and cannot be reconciled from + in-repo evidence. +- **U4.** Whether an MSTest-abandoned `async` continuation later resumes — releasing the gate late + rather than never — is not verified. Deciding it requires either testfx source inspection or an + experiment. + +--- + +## 4. Root cause analysis + +### 4.1 The production defect, which is not in dispute + +Eight executable sites in the `QfcItemController` partial class obtain a UI-marshalling primitive +directly from the viewer rather than through the `UtilitiesCS.Threading.IUiDispatcher` seam that the +controller already accepts by injection: + +| Channel | Sites | +|---|---| +| `_itemViewer.UiSyncContext` | `QuickFiler/Controllers/QfcItemController.ViewerSetup.cs` lines 64, 282, 287, 298, 303 | +| `_itemViewer.UiDispatcher` | `QuickFiler/Controllers/QfcItemController.ViewerSetup.cs` line 371, plus one site each in the Initialization and FolderHandling partials | + +`QuickFiler/Viewers/ItemViewer.cs` captures both primitives in its constructor at lines 23-29, from +`SynchronizationContext.Current` and `Dispatcher.CurrentDispatcher`, and publishes them read-only. A +test therefore cannot supply either one without a live WinForms message loop. + +Compounding this, `QfcItemController` reaches the viewer through 14 `(ItemViewer)_itemViewer` concrete +casts plus one concrete signature, `internal async Task ResolveControlGroupsAsync(ItemViewer itemViewer)` +at line 276 of `QuickFiler/Controllers/QfcItemController.ViewerSetup.cs`. At line 288 that method calls +`itemViewer.GetAllChildren()`, an extension method on `System.Windows.Forms.Control`, which cannot be +invoked through `IItemViewer` at all. **This is the single most important design conclusion available: +making the marshalling injectable does not by itself make the tests cheap.** As long as the concrete +casts stand, every test of those members must construct a real viewer. + +The construction cost is structural: `QuickFiler/Viewers/ItemViewer.cs` calls `InitializeComponent()` +unconditionally, and the Designer partial is 6,223 lines containing 110 control constructions including +two WebView2 children whose `EndInit()` calls create their handles, which in turn creates the parent's +handle. + +### 4.2 Two competing mechanisms for the expiry, neither yet measured + +The spec deliberately does not pick between these. Acceptance criterion 1 exists to settle it. + +**Hypothesis H-COST — raw elapsed fixture cost.** The real elapsed cost of the control-tree +construction, inflated by coverage instrumentation and by CPU contention from the other assemblies in +the combined run, crosses the 60,000 ms bound. Favoured by the #729 research. Predicts expiries that +arrive **independently** of one another. + +**Hypothesis H-LEAK — a leaked or late-released transaction.** MSTest 4.4.0 is configured with +`useCooperativeCancellation` at its default of `false`, and the authoritative Microsoft Learn wording +for the non-default `true` setting is that it "will only trigger cancellation of the `CancellationToken` +but will **not stop observing the method**". At the repository's configuration the adapter therefore +does stop observing a timed-out method. For an `async Task` test there is no mechanism to abort a +suspended state machine, so the remainder of the method — including the `finally` that calls +`harness.Restore()` and thence `UiThreadDispatcherTransaction.Dispose` and +`ReleaseTransactionGate` — is not awaited. Every subsequent acquirer then blocks on a permit whose +holder the runner already considers finished. Predicts a **cluster** of expiries following one initial +failure, and an unbounded hang on the four gate-taking tests that carry no `[Timeout]` at all. + +The #511 spec recorded H-LEAK precisely at its lines 132-139 and explicitly left it unfixed. It +survives #493 verbatim with `TransactionGate` substituted for the removed name. + +**Discriminating observable.** The two hypotheses are distinguished by whether the permit is free at +acquisition. Under H-COST every acquisition on a serial run finds the permit free and the elapsed cost +is charged to construction; under H-LEAK at least one acquisition finds the permit held with no live +holder. This is the observable that criterion 1 requires to be declared before the measuring run and +recorded after it. + +**Note on serial execution.** `QuickFiler.Test` declares no `[assembly: Parallelize]`; the only +parallelization attributes in the assembly are two `[DoNotParallelize]` class attributes in the helper +tests. Under CI's serial ordering the simple queue-wait story cannot arise, which narrows the gate +hypothesis sharply to its leak variant. Cross-assembly parallelism does not contend on this static +gate, which lives only in `QuickFiler.Test`, but it does contend for CPU. + +--- + +## 5. Scope and non-goals + +### 5.1 In scope + +- An **additive** UI-marshalling seam that lets `QfcItemController` members which do not require a real + Win32 message loop be exercised without constructing the full pump fixture. +- Instrumentation sufficient to decide between H-COST and H-LEAK, and the corresponding fix for + whichever is found operative. +- A deterministic regression test for the identified mechanism. +- Reconciliation of the forward pointers on #511 and #571. + +### 5.2 Explicit non-goals (each is a hard prohibition, not a preference) + +1. **No timing tolerance of any kind.** Raising `PumpTimeoutMs`, scaling it by core count, scaling it + by measured machine speed, adding a retry, adding a sleep, adding a `Stopwatch`-based tolerance, or + applying `[Ignore]` are all forbidden. This is the inherited epic constraint and it remains in force. +2. **No fake `SynchronizationContext` replacing the real message pump in the existing pump-hosted + tests.** Those tests keep `WinFormsPumpHost` and keep exercising the real message loop. Their + coverage contribution is exactly what this constraint protects. A nuance the plan must not trip + over: a `DrainableSynchronizationContext` test double already exists in the assembly and is used by + breadcrumb tests that never used the pump. Its existence is not a precedent for introducing one into + a pump-hosted test. +3. **The final clause of the inherited #729 recommendation is rejected.** That recommendation ends + "...so a synchronous fake can replace the message loop **entirely**." The seam is adopted; the word + "entirely" is what fails. A partial, additive seam is permitted and is the intended remedy. Recorded + in full in the constraint-conflict artifact listed in section 11. +4. **The seam must be additive to `IItemViewer`, never a replacement.** Reflection contract tests at + lines 248 and 264 of QuickFiler.Test/Viewers/ItemViewerBreadcrumbDropDownContractTests.cs assert that + `UiDispatcher` and `UiSyncContext` still exist as declared members, with the stated reason that + `UiDispatcher` "still has production consumers and must survive". Removing, renaming or narrowing + either member fails existing tests. +5. **`[Timeout(PumpTimeoutMs)]` is not to be removed.** It is a documented deadlock guard, not the + load-sensitivity source. Removing it trades a bounded, diagnosable failure for an unbounded CI hang. +6. **No interface over the `WebView2` control.** Rejected: it addresses at most the eight breadcrumb-host + tests, whose measured durations are already 0.018 s to 0.16 s, i.e. the cheapest tests in the + population; and it would require the interface to carry two events and `ConditionalWeakTable` key + identity, which is disproportionate. The control is already constructor-injected today; what is + concrete is its type. +7. **No `[DoNotParallelize]` on the six gate-taking classes.** A no-op under CI, and under a + `/Settings:`-driven run it would serialize classes the gate already serializes. It would also make + the H-LEAK cascade deterministic rather than order-dependent, which is worse for diagnosis. +8. **No shared pump host or shared viewer instance across a test class.** This is the single + highest-leverage cost reduction available but it introduces order-coupling between tests, contrary + to the independence principle in the repository's general unit-test rule. Recorded here as + considered-and-rejected; promote it separately if it is ever wanted. +9. **No `.trx` and no `.cobertura.xml` committed.** See section 8. +10. **No edits to the WebView2 breadcrumb host or to the Initialization and FolderHandling controller + partials.** Deferred, with reasons in section 6.4. + +### 5.3 Constraint deliberately re-opened + +**Production edits ARE permitted for this item, and only for this item.** The +`quickfiler-suite-determinism-foundation` epic forbade them; #743 exists because the defect cannot be +closed without them. The other two epic prohibitions (non-goals 1 and 2 above) remain in force. + +--- + +## 6. Proposed fix + +### 6.1 Invariant + +Every UI-thread marshal performed by `QfcItemController` on behalf of a member that does not create or +manipulate a Win32 window handle must go through the injected `IUiDispatcher`, so that the marshaller +is substitutable; and every marshal performed by a member that does create or manipulate a handle must +continue to go through the real message pump, so that no coverage or guarantee is lost. The seam +changes **which marshaller is chosen**, never **whether a real pump exists**. + +### 6.2 Part A — route the interface-reachable marshalling sites through the existing seam + +The controller already declares an `IUiDispatcher _uiDispatcher` field, already accepts it by +injection, already defaults it to `WpfUiDispatcher` in the production path, and the test assembly +already has a synchronous double for it. No new abstraction is introduced and no new injection wiring +is required. + +In `QuickFiler/Controllers/QfcItemController.ViewerSetup.cs`, replace the `await _itemViewer.UiSyncContext` +and `_itemViewer.UiDispatcher.InvokeAsync(...)` forms at lines 282, 287, 298, 303 and 371 with +`_uiDispatcher`-mediated marshals. + +Line 64 is **not** converted in this item. It sits inside `InitializeWebViewAsync`, which is excluded +from coverage measurement and whose residual barrier is a real WebView2 runtime, an external process +barred by the unit-test policy. Converting it would change nothing measurable and would enlarge the +diff on a contended file. + +Two risks must be established **before** the edit, not after: + +- `await ctx` and `IUiDispatcher.InvokeAsync` are not the same primitive. A WinForms + `SynchronizationContext` and a WPF `Dispatcher` are different queues on the same thread. Production + ordering on the UI thread must be shown unchanged. +- `_uiDispatcher` is null until `SaveParameters` applies its default, and the assembly already records + an observed null in the seam-factory tests. Every converted site needs the same null tolerance the + existing sites have. + +### 6.3 Part B — remove the concrete-viewer dependency from `ResolveControlGroupsAsync` + +Widen `ResolveControlGroupsAsync(ItemViewer)` to accept `IItemViewer`. This is the change that actually +removes the need to construct a real viewer for that member, and therefore the change that Part A alone +does not deliver. + +It requires two **additive** members on `QuickFiler/Viewers/IItemViewer.cs`, implemented on +`QuickFiler/Viewers/ItemViewer.cs`: + +1. A descendant-control enumeration replacing the `GetAllChildren()` extension call at line 288 of + `QuickFiler/Controllers/QfcItemController.ViewerSetup.cs`, which cannot be invoked through the + interface. +2. An accessor for the item-number label consumed at line 281. The interface publishes + `ItemNumberText` as a string but not the underlying `Label`, and the call site needs the control. + +The widening is source-compatible for existing callers passing a concrete viewer. The precedent for +adding intent members to this interface is already established in the same file: the display-state +members at lines 39-52 and the re-declared `InvokeRequired` / `Invoke` / `BeginInvoke` trio at lines +192-194 were added for exactly this reason. `QuickFiler/Viewers/IItemViewer.cs` is 200 lines against +the 500-line cap, so there is ample headroom. + +The `#230` justification comment at lines 272-275 of +`QuickFiler/Controllers/QfcItemController.ViewerSetup.cs` names the test that covers the de-exempted +member and **must** be updated to name the retained test, per the de-exemption rule restated in +section 7.3. + +**Dependency to confirm at Phase 0.** The determinism epic assigned `IItemViewer` rewriting to issue +#489. Its display-state members are present in the tree, so #489 landed at least partially, but its +disposition was not confirmable during preparation. Confirm it before executing Part B; if #489 is +still open, coordinate or defer Part B and deliver Part A plus the mechanism work alone. + +### 6.4 Part C — the mechanism fix, branch-dependent + +Which branch executes is decided by criterion 1, not by this spec. + +- **If H-LEAK is operative:** move the gate release out of the abandoned async path in + `QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs`, for example by + anchoring it to a `[TestCleanup]`- or `[AssemblyCleanup]`-reachable owner rather than to the timed-out + test's own `finally`. Add the deterministic regression test to + `QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixtureTests.cs`, which is 353 lines + and has 147 lines of headroom. +- **If H-COST is operative:** Parts A and B are the fix, and + `QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs` is touched only by the + instrumentation needed to record the discriminating observable, which is then either retained as a + permanent assertion or reverted. + +### 6.5 Deferrals, stated as prose without paths so the scheduler does not serialize on them + +The two marshalling sites in the Initialization and FolderHandling controller partials are **not** +converted in this item. Both partials are near the 500-line cap (Initialization is 497 lines, three +lines of headroom), both are single `UiDispatcher` reads, and converting them adds contended surface +without changing any measured figure. The existing viewer-setup test file is 498 lines with two lines +of headroom, so no test may be added to it; the interface widening is source-compatible, so it is +expected to compile unchanged, and the plan must verify that expectation rather than assume it. The +WebView2 breadcrumb host is out of scope per non-goal 6 and is concurrently edited by a sibling item. + +--- + +## 7. Test disposition + +Every test the item touches is classified below. A test may be placed in the MOVED category only with a +stated justification that it does not depend on real Win32 handle creation or `Control.BeginInvoke` +marshalling. + +### 7.1 Touched tests + +| Test / file | Classification | Justification | +|---|---|---| +| New seam tests in `QuickFiler.Test/Controllers/QfcItemController.SeamMarshallingTests.cs` covering `ResolveControlGroupsAsync` through `IItemViewer` | **MOVED to the seam** | The member reads labels, enumerates descendant controls and marshals.

They keep the real message loop and their existing timeouts. + +- The eight pump-hosted initialization tests in QuickFiler.Test/Controllers/QfcItemController.InitializationTests.Part3.cs. +- The two pump-hosted seam-factory tests in QuickFiler.Test/Controllers/QfcItemController.SeamFactoryTests.cs. +- The one pump-hosted test in QuickFiler.Test/Controllers/QfcItemController.ViewerSetupTests.cs.

Note the + correct directory: these are under the Viewers folder of the test project, not the Controllers folder. +- The reflection contract tests in QuickFiler.Test/Viewers/ItemViewerBreadcrumbDropDownContractTests.cs, + which are the guard that keeps the seam additive. + +### 7.3 De-exemption coverage rule, inherited and binding + +Every one of the pump-hosted consumer tests is the named coverage evidence for at least one de-exempted +production member. Deleting, `[Ignore]`-ing, or reclassifying any of them out of the unit suite +invalidates the corresponding `#230` justification comment and re-opens the exemption question. The +affected comment blocks are in the Initialization partial and at lines 272-275 of +`QuickFiler/Controllers/QfcItemController.ViewerSetup.cs`; the line numbers recorded in the #511 spec +are pre-drift and must be re-derived before use. + +### 7.4 Determinism rules for new tests + +No `Thread.Sleep`, `Task.Delay`, `Stopwatch`, wall-clock comparison, retry loop or polling loop in any +new or modified test.

All five must be satisfied. + +- [ ] **AC1 — Mechanism identified by measurement, not inference.** An evidence artifact under this + feature folder's evidence/baseline directory names which of the two candidate mechanisms defined in section 4.2 — + H-COST (raw elapsed fixture cost) or H-LEAK (a leaked or late-released `TransactionGate` permit) — is + operative, and does so from a direct instrumented observation. The artifact PASSES only if it contains + all four of: (i) the discriminating observable stated in advance, namely whether any acquisition of + the one-permit `TransactionGate` finds the permit held with no live holder; (ii) the measured value of + that observable, with the command and the load condition under which it was measured; (iii) the + rejected hypothesis named explicitly together with the observation that rejects it; and (iv) the + per-test elapsed durations that bound the contribution of construction cost. It FAILS if it reasons + only from static reading, if it identifies the mechanism as `UiThreadDispatcherGate` or + `SwapUiThreadDispatcher` (which exist in zero `.cs` files, per correction C1), or if it reports + agreement with both hypotheses.

There is no end-user impact: no Outlook user sees different behaviour as a result of +this defect, and no production code path is known to be incorrect. Severity is Medium for exactly that +reason. + +## The narrative + +A maintainer or an agent runs the C# toolchain as CLAUDE.md defines it, ending in +`vstest.console.exe` with coverage enabled. On an idle machine the QuickFiler test assembly passes. On +a loaded machine — another build running, a coverage-instrumented multi-assembly run, idle MSBuild +node-reuse processes holding CPU — a handful of pump-hosted controller and breadcrumb-host tests stop +after approximately sixty seconds each and report a timeout rather than an assertion failure. Re-running +the identical tree with the machine idle passes. + +The consequence is not a wrong answer; it is a lost signal. A gate that fails for reasons unrelated to +the change under test stops being usable as evidence. An agent that sees it has no principled way to +distinguish "this change broke something" from "this machine was busy", and the cheapest available +response — rerun until green — is precisely the habit the repository's determinism rules exist to +prevent. + +The defect has now been reported three times: as #711, as part of #729, and as #592, which also +absorbed #511 and #571. Twice it was closed without being fixed, because the fix requires editing +QuickFiler production code and the owning items were scoped test-only. This item exists to stop that +happening a third time, and the production-edit prohibition is re-opened here specifically so it can be +closed. + +## What "fixed" looks like from the maintainer's seat + +Three things, in order of how much they matter. + +First, the maintainer can point to a measurement — not an argument — that says what actually causes the +sixty-second expiry. Two mechanisms are currently live candidates: the real elapsed cost of building a +6,223-line Designer control tree with two handle-created WebView2 children, and a test-fixture +semaphore permit that is never released because MSTest stops observing a method it has timed out. The +evidence in this folder supports both and settles neither. The maintainer's first lead, which named two +specific helper identifiers, has been checked and those identifiers exist in no source file in the tree; +they were removed under issue #493 and replaced. That correction is recorded so nobody spends time +instrumenting something that is not there. + +Second, a single deterministic test reproduces whichever mechanism is found, and does so without a +sleep, a retry, or a timing tolerance of any kind. This matters more than any number of green runs. A +deterministic test has no base rate, so it needs one run to be convincing, whereas the historical +failure rate of roughly one run in twenty-one means that thirty consecutive clean runs would occur by +chance about once in every four attempts even if nothing had been fixed. Sixty-two clean runs would be +needed to reject that null at the five-percent level, and sixty-two loaded full-suite runs would take +roughly fifteen hours. The statistical evidence is therefore scoped to a targeted reproduction and kept +as a supporting signal behind the deterministic one. + +Third, nothing is lost in the trade. The pump-hosted tests that today provide the coverage evidence for +several de-exempted production members stay on the real Win32 message loop. The seam this item adds is +additive, and its purpose is narrow: to let the members that never needed a real message loop be tested +without paying for one. There are existing reflection-based contract tests in the assembly that assert +the two marshalling members of the viewer interface still exist, and they are the guard that keeps the +change additive rather than substitutive. + +## What the maintainer explicitly does not want + +The prohibitions matter as much as the goal here, because every cheap "fix" for this class of defect +destroys the thing being protected. + +Raising the sixty-second bound, scaling it to the machine, or retrying is forbidden. Replacing the real +message pump in the existing pump-hosted tests with a fake synchronization context is forbidden; the +inherited recommendation this item is built on ends with a clause proposing exactly that, and the clause +is rejected while the rest of the recommendation is adopted. Removing the timeout attribute is +forbidden, because it is a deadlock guard and removing it converts a bounded, diagnosable failure into +an unbounded hang. Sharing one viewer across a test class would be the single cheapest speed-up +available and is also rejected, because it couples tests to each other's ordering. + +## What remains honestly unknown + +This story does not claim more than the evidence supports. + +The identity of the seven tests that expired in the one recorded genuine failure cannot be recovered: +the underlying result file is not in this worktree, and the branch holding it never merged. There is no +committed artifact of an actual expiry anywhere in the tree. Whether the semaphore leak has ever +actually occurred is untested; there is weak evidence against it, since a leak should have hung one of +the four gate-taking tests that carry no timeout at all, but test ordering is not pinned so that is not +proof. An earlier report counted fourteen failing tests where a later one counted seven; those were two +different days under two different commands and they cannot be reconciled from what is in the +repository. + +Each of these is carried forward as an open question rather than resolved by assumption, and the +acceptance criteria in the spec are written so that an honest negative result is recorded as such +rather than dressed up as a pass. + +## Related records + +Issues #711, #729, #592, #511, #571, #493 and #489. The last of these owns the viewer-interface surface +and its current disposition must be confirmed before the interface-widening part of the work proceeds.

Its **uncommitted** files are readable by absolute path. + +**Why:** on 2026-09-12 a preparation-mode run for issue #743 died on an account-wide rate limit +holding the only copy of a spec, a user story and a mid-authoring plan. Reconstructing them would +have cost hours; recovering them cost four commands. + +**How to apply:** + +1. `git -C cat-file -t ` — it resolves, because the object store is + shared. `git ls-tree -r --name-only -- ` then enumerates what it committed. +2. Restore committed content byte-exact with `git -C checkout -- /`. + This also stages it, which `git add`/`git commit` gates do not object to. +3. For an **uncommitted** file, `git -C hash-object -w ` works, then `git cat-file blob > `. Re-`hash-object` your copy and + compare SHAs to prove byte-identity and preserve LF. See [[byte-exact-copy-via-git-plumbing]]. +4. **`git -C ...` is REFUSED** by the isolation filter ("a worktree-isolated + agent's git operations must target its own worktree"), so you cannot read the predecessor's + `git status` or `git log`. Substitute the `Glob` tool over its folder and compare the file list + against `ls-tree` of its last commit — a file present on disk but absent from the tree is its + uncommitted work. +5. **Prove the citation base matches before trusting inherited line numbers.** + `git diff --name-only ` — if it lists only docs, the predecessor's + citations were derived against your exact source tree. That converts a full re-derivation into a + spot check. Do the spot check anyway; see [[imported-checkpoint-recorded-pass-is-not-evidence]]. +6. Commit and **push** the recovered work before starting any new work, so it stops being + single-copy. Do not write into the other worktree. + +Also: an inherited checkpoint's `model_budget.fable_policy` may differ from your session's. Recompute +the routing rather than inheriting the receipts — see [[model-routing-feature-review-is-always-fable]].

The production default seam is constructed at line 391 of the Initialization controller partial as `new UtilitiesCS.Threading.WpfUiDispatcher()`, whose parameterless constructor resolves its dispatcher lazily through `() => UiThread.Dispatcher` (lines 24-25 and 33-37 of `UtilitiesCS/Threading/WpfUiDispatcher.cs`) and whose `InvokeAsync(Action)` forwards 1:1 to `Dispatcher.InvokeAsync(action).Task` (line 43). This is the same primitive with the same delegate and the same queue, so the substitution is like-for-like and net zero lines. +- **Line 371 IS converted.** It is `await _itemViewer.UiDispatcher.InvokeAsync(...)`, a controller-performed marshal with a delegate argument.

This is the same primitive with the same delegate and the same queue on the non-null path, so the substitution is like-for-like there; the converted site additionally carries the null tolerance spec section 6.2 requires (P1-T2, P3-T2), which adds a net three to five lines to the file (467 to between 470 and 472 before the P3-T3 comment, depending on whether the formatter keeps the replacement single-line marshal on one line; the three-line original is replaced by one statement plus a five-line null block). - **Lines 282, 298 and 303 are NOT converted.** Each passes `_itemViewer.UiSyncContext` as the second **argument** of `QfcTipsDetails.CreateAsync(Label, SynchronizationContext, CancellationToken)`, declared at line 80 of the UtilitiesCS tooltips helper file. That file is in the `UtilitiesCS` project and is not in the binding Write Set. Converting these sites would require changing a public UtilitiesCS API signature, which is out of scope. They are argument-passing sites, not marshals the controller performs. -- **Line 287 is NOT converted.** It is `await itemViewer.UiSyncContext;`, a context **hop** after which every subsequent statement runs on the UI thread. The injected seam interface declares only `Invoke(Action)`, `InvokeAsync(Action)`, `InvokeAsync(Action, DispatcherPriority, CancellationToken)`, `BeginInvoke(Action)`, `InvokeAsync<TResult>(Func<TResult>)` and `InvokeAsync<TResult>(Func<Task<TResult>>)` (lines 15 to 42 of `UtilitiesCS/Threading/IUiDispatcher.cs`). None of these is a hop. An equivalent conversion requires wrapping lines 288 through 328 inside a delegate, which is a restructure of a file with 33 lines of headroom that a sibling item is concurrently editing. Spec section 6.2 requires ordering equivalence to be **established before** the edit; it cannot be established for this site within the Write Set, so the site is deferred with this reason recorded. +- **Line 287 is NOT converted.** It is `await itemViewer.UiSyncContext;`, a context **hop** after which every subsequent statement runs on the UI thread.

Two additive interface members replace the two concrete-only reads in its body. Re-derived: the descendant enumeration at line 288 is an extension method on `System.Windows.Forms.Control`, declared at line 146 of `UtilitiesCS/Extensions/WinFormsExtensions.cs` in namespace `UtilitiesCS`, and the interface does not derive from `Control`; the item-number label read at line 281 reaches a concrete member the interface does not publish. +**D5 — Part B is the substantive fix and is what removes the construction cost.** `ResolveControlGroupsAsync` is widened from the concrete viewer type to the viewer interface.

Neither removes, renames nor narrows `UiDispatcher` or `UiSyncContext`, so the reflection contract tests at lines 248 and 264 of the breadcrumb drop-down contract test file continue to pass. **D7 — The fail-before is a runnable, defect-preserving seam, not a compile error.** Phase 2 widens the signature while deliberately retaining the concrete dependency as two explicit casts of the form `(ItemViewer)itemViewer`. A Moq proxy for the viewer interface does not derive from the concrete viewer class, so those casts throw `InvalidCastException` deterministically, with no timing dependency. Phase 3 replaces the casts with the additive interface members and the same tests pass. This preserves the exact pre-change defect ("the member cannot be driven without a concrete viewer") while making it observable from a test. -**D8 — The seam tests install an ambient `SynchronizationContext`.** The awaiter extension `GetAwaiter(this SynchronizationContext)` is declared at line 198 of `UtilitiesCS/Threading/UiThread.cs`; its `IsCompleted` returns true at line 162 when the awaited context is reference-equal to the ambient context. The seam tests therefore install the same context instance the viewer mock returns as `SynchronizationContext.Current` for the duration of the test and restore the previous value in a `finally`, exactly as the existing headless viewer-setup test does at its lines 391-392 and 412. With that arrangement every `await <context>` in the call graph completes inline and **no message pump is required**. This is permitted: spec non-goal 2 bars replacing the real pump in the existing pump-hosted tests, and the seam-design-constraints artifact states explicitly that a context double in a test that never used the pump is not barred.

an existing 498-line test off the Write Set; the fixture's R4 test deliberately contends the TransactionGate so a serial "contended count 0" rule is non-discriminating; the coverage runner throws at line 236 before post-processing on ANY failing test +metadata: + type: project +--- + +Three plan-shape facts found while preflighting the #743 plan (`plan.2026-09-12T13-23.md`). + +1. **`_uiDispatcher` is null under the parameterless `HarnessController`.** `QfcItemController.TestSupport.cs` 162-165 records it; the field is assigned only at Initialization.cs 59 / 391. The existing test `AssignControlsAsync_DispatchesAssignThroughViewerDispatcher` (ViewerSetupTests.cs 309-344, file at 498 lines, NOT in the Write Set) injects only `_itemViewer` + `_globals`. Any conversion of `_itemViewer.UiDispatcher.InvokeAsync` (ViewerSetup.cs 371) to `_uiDispatcher.InvokeAsync` with no null tolerance makes that test NRE and the whole-assembly `failed=0` gate unsatisfiable. Spec 6.2's second risk bullet REQUIRES "the same null tolerance the existing sites have"; the reference shape is `NotifyMoveFailure` at MailActions.cs 35-46 (local copy, direct call when null). + +2. **R4 (`Transaction_SecondCallerCannotInstallUntilTheFirstRestores`, FixtureTests.cs 204-262) starts a second transaction while the first is held.** In the SERIAL regime it contributes 0 or 1 "contended acquisition" per run nondeterministically, so any decision rule of the form "serial contended count > 0 => leak" is polluted by design. Exclude it by `FullyQualifiedName!~` from the measurement run and say why. R4 is also the #823 known-intermittent (1 failure in 4 parallel-regime runs per the flake-watch log), so 62-run streaks over its class will not stay clean. + +3. **`Invoke-MSTestWithCoverage.ps1` throws `MSTest with coverage failed with exit code` at line 236 on ANY non-zero vstest exit**, which is BEFORE `ConvertTo-KoverageCoberturaXml` at 342. A single flaky test leaves the raw document with absolute filenames, and a per-file XPath on workspace-relative backslash filenames returns zero class nodes.

Without LogFileName= vstest names the TRX from the account name and host name, and any step that transcribes that filename into committed evidence leaks both. The brief counted seven spans; re-derivation found eight (P4-T3 carries a serial and a parallel span on one line) and all eight are corrected in place. Acceptance-condition-neutral: no assertion, threshold or task ordering changed.

Row 1 is selected. + +**REJECTED hypothesis: H-LEAK** (a leaked or late-released transaction leaving the one-permit gate held with no live holder). **Observation that rejects it:** across the whole serial-regime run of 1394 tests, with the only designed live-holder contention test excluded, every one of the 11 acquisitions found the permit free (`contended=0`), and at the moment the balance test held the permit the acquisition and release counters differed by exactly 1, so no earlier transaction in the run had been left unreleased. A serial run cannot queue a second live holder; therefore a contended count of zero in that regime is a direct observation that the permit was never found held by a leaked transaction. + +**Operative mechanism (exactly one): H-COST** — the elapsed cost of the pump-hosted fixtures themselves, elongated under load, is what consumes the per-test bound. The parallel-regime contended count of 14 does not contradict this: in that regime distinct test classes genuinely queue on the gate with a live holder, and its balance test also passed with difference 1, so those 14 contended acquisitions were live-holder queueing rather than leaks. The two hypotheses are not both supported; only H-COST survives. + +## (iv) Elapsed durations bounding the construction-cost contribution + +Serial-regime (P1-T9) `ThroughThePumpHost` durations, transcribed: + +| Test | duration (ms) | +|---|---| +| InitializeGraphicsAsync_ThroughThePumpHost_CompletesAndAppliesDarkTheme | 85.2421 | +| InitializeBool_ThroughThePumpHost_CompletesAndInitializesState | 81.7954 | +| InitializeNineArgOverload_ThroughThePumpHost_SavesParametersAndDelegates | 85.7493 | +| InitializeAsync_ThroughThePumpHost_RunsToTheMockedWebViewSeamAndFaults | 124.5081 | +| InitializeSequentialAsync_ThroughThePumpHost_CompletesAndInitializesState | 111.1364 | +| ResolveControlGroupsAsync_ThroughThePumpHost_PopulatesTipsAndControlGroups | 68.1703 | + +Largest serial duration: 124.5081 ms.

Under that regime the largest measured duration times the upper multiplier, 6,460.4 ms x 26 = 167,970 ms, exceeds the 60,000 ms bound; this is the reachable path by which elapsed fixture cost, not a gate leak, can consume the per-test timeout when class-level parallelism and CPU saturation coincide. It is consistent with, and does not replace, the counter-based identification above. + +## Expiry statement (recorded negative result) + +Neither instrumented run produced any expiry: the serial run recorded `timeout=0` and `failed=0` over 1394 tests, and the parallel run recorded `timeout=0` and `failed=0` over 1395 tests. No `PumpTimeoutMs` or `GateTimeoutMs` expiry was reproduced in this session. This is stated plainly as a negative result.

A `System.Windows.Forms.Control` constructor calls `WindowsFormsSynchronizationContext.InstallIfNeeded`, which replaces an ambient context whose exact type is `SynchronizationContext` with a `WindowsFormsSynchronizationContext`. The awaiter at UtilitiesCS/Threading/UiThread.cs lines 155-190 therefore never took its reference-equality inline branch; each continuation was posted to a WinForms context that is never pumped on the MSTest STA thread, which is the same mechanism the UtilitiesCS `QfcTipsDetails_Tests.CreateAsync_*_WithMatchingSyncContext_*` tests (lines 654-680, 696-720) avoid by constructing the controls first and installing the context afterwards. + +Correction, confined to the Write Set file `QuickFiler.Test/Controllers/QfcItemController.SeamMarshallingTests.cs`: every control is now constructed before the ambient context is installed, and the class remarks record the ordering rule. This satisfies P2-T6 as written (the task fixes only "install it ... before the act"). The P2-T6 gate counts were re-verified after the rewrite: `[TestMethod]` = 5, `WinFormsPumpHost` = 0, `[Timeout(` = 5, banned constructs = 0; post-format line count 312 (at most 400). The P2-T9 fail-before evidence is unaffected in substance: its three failures were raised by the two `(ItemViewer)itemViewer` casts and the null `UiDispatcher` read, all of which execute before any `await` and are independent of the arrangement order. The fail-before ran against the earlier text of the test file, which is preserved in the Phase 2 commit (bce81049). + +## Results directories deleted + +`coverage\trx\p3-t6-1`, `coverage\trx\p3-t6-2` and `coverage\trx\p3-t6-3` were deleted after transcription; `Test-Path` printed `False` for each and the `p3-t6-*` directory count under `coverage\trx` is `0`.

PASS. + +### `QuickFiler.Test/Controllers/QfcItemController.SeamMarshallingTests.cs` (new, 312 lines) + +- Class remarks (18-36) document the inline-await mechanism and the "controls before ambient context" ordering rule with the reason (`Control` constructor calls `WindowsFormsSynchronizationContext.InstallIfNeeded`, which replaces an ambient context of exact type `SynchronizationContext`). The reason is consistent with documented .NET Framework behaviour and is empirically confirmed by the first pass-after attempt's two timeouts recorded in `ac2-pass-after-three-runs`. This review did not inspect framework source. +- Helpers build panel-parented labels (the tooltip factory's parent resolution accepts exactly `TableLayoutPanel` or `Panel`) and a descendant set containing one `TableLayoutPanel` and one `Button`, so the control-group assertions are non-vacuous. Everything is parented on a `using`-scoped `Panel`, so disposal is deterministic. +- Determinism: no sleep, delay, stopwatch, wall-clock read, retry or polling loop; the `for` in `BuildHostedLabels` is a fixed-count constructor loop. The single `[Timeout(SeamTimeoutMs)]` per test is a deadlock bound. Ambient context installed and restored in `try`/`finally`. PASS. +- Assertions: test 2's `Verify(v => v.DescendantControls(), Times.Once())` and test 5's `dispatcher.Verify(d => d.InvokeAsync(It.IsAny<Action>()), Times.Once())` are the interaction checks that bind the outcome to the seam. Test 1's `NotBeAssignableTo` is tautological (N-5). Test 4 uses `new Mock<IItemViewer>()` without setups, which is correct because the token check precedes any read. +- `BuildSyncDispatcher()` (`TestSupport.cs` 105-140) runs the delegate inline and returns `Task.CompletedTask`, so `viewer.VerifySet(v => v.ItemNumberText = "2", Times.Once())` in test 5 proves the assignment ran inside the seam call.

Required because the project enumerates sources explicitly. PASS. + +## Orchestrator-requested assessments + +1. **AC2(i) same-test requirement.** PASS with a recorded deviation. The fail-before runs (P2-T9, commit `bce810495`) executed an earlier text of the seam test file in which the ambient context was installed before the WinForms controls were constructed; the pass-after runs (P3-T6, commit `cc236c8d2`) executed the corrected order. The fail-before outcome is unaffected, for three reasons that rest on the recorded evidence rather than on the executor's assertion: (a) all three fail-before runs record `InvalidCastException: Unable to cast object of type 'Castle.Proxies.IItemViewerProxy' to type 'QuickFiler.ItemViewer'` for tests 1 and 2, which can only be raised by the `(ItemViewer)itemViewer` cast that P2-T3 placed in the argument expression of the first `QfcTipsDetails.CreateAsync` call; C# evaluates that argument before the call, before the first `await` in the member, so the returned `Task` is faulted synchronously; (b) had execution reached an `await` under the old arrangement, the test would have hung and expired, exactly as the first pass-after attempt did on the fixed tree; the recorded outcome is an exception, not a timeout, which is itself proof the failure precedes any await; (c) test 5's `NullReferenceException` arises from `_itemViewer.UiDispatcher.InvokeAsync` on a mock that returns null for the sealed `Dispatcher` type, also before any await. The arrangement change affects only what happens after the first await. Residual: the final test text was never literally run against the intermediate; the claim that the correction was confined to arrangement order could not be checked by diff in this review (no shell) and rests on the artifact's statement plus the per-test "controls first" comments at lines 138, 184 and 279. A literal re-run of the final file against the `bce810495` production tree is the strictly conforming evidence and is cheap; it is recommended, not required. +2. **`user-story.md` in a `full-bug` folder.** A policy deviation of Observation severity, recorded as Non-blocking in the table. The lifecycle skill's wording is "should be absent unless the requirements explicitly justify it"; the file exists, is explicitly marked non-authoritative, carries no checkboxes and no acceptance criteria, and the spec's own preamble names itself the sole AC source. No AC-tracking ambiguity results, and `minor-audit` integrity rules (which would make the file an integrity failure) do not apply to `full-bug`. Either deleting it at merge or keeping it is acceptable. +3. **Evidence hygiene.** Grep over the feature folder for the user-profile prefix in both separator forms, the account name and the bare `Users` segment with either separator: exactly one hit, `evidence/other/orchestrator-citation-verification.2026-09-12T13-50.md` line 6. Severity: Blocking, consistent with the prior rulings on issues #752 and #645 in this repository (a preparation-session file added by the branch publishes the account name to `main`; the executor's Write Set scope lock does not discharge the obligation). `evidence/baseline/phase0-toolchain-bootstrap.2026-09-12T16-30.md` line 7 carries a `C:\Program Files\...\MSBuild.exe` path; it names no account or host and is an observation only. Grep over the seven Write Set files: zero hits. Projections-only audit: `git ls-files` count of raw artifacts identical at the anchor and at the final tree (570), zero untracked; PASS. +4. **Out-of-scope defects.** Enumerated as follow-ups in the table (Meziantou HintPath skew, confirmed by Grep at `UtilitiesCS.csproj:1308` and `VBFunctions.csproj:58` versus `3.0.235` at lines 1300 and 73; Deedle `TypeInitializationException` in `QfcInitEmailQueueZeroBatchTests` under class-level parallelism). Neither is a finding against this item; both should be promoted to issues so they are not lost at merge. +5. **Null-tolerance branch in `AssignControlsAsync`.** Reachability in production: unreachable, established by reading every assignment of `_uiDispatcher` and every caller of the member. `_uiDispatcher` is assigned in the primary constructor (`Initialization.cs` line 59, followed by `SaveParameters` at 67), by `??=` inside `SaveParameters` (391), and in both static factories (438 and 480, each followed by `SaveParameters` at 441 and 483). The only constructor that assigns nothing is `protected QfcItemController() { }` at line 27; its only subclass is `HarnessController` (`TestSupport.cs` 28-32), and `TestSupport.cs` lines 162-165 record that the harness deliberately does not default the field. `AssignControlsAsync` is reached only from `PopulateControlsAsync` (`ViewerSetup.cs` 361), which is called from `InitializeAsync` (`Initialization.cs` 233) and line 325, both after `SaveParameters` has run on every production route. The branch is therefore reachable only from tests that build a `HarnessController` without injecting `_uiDispatcher`, which is exactly `AssignControlsAsync_DispatchesAssignThroughViewerDispatcher`. The plan's P1-T2 artifact reaches the same conclusion with the same citations. Comment adequacy: the first sentence states the reachability correctly; the second sentence ("so this is no no-op") is unclear and should be reworded (N-1). Design note: a production branch that exists for a test harness is a smell, but it is the shape spec 6.2 mandates ("Every converted site needs the same null tolerance the existing sites have") and matches the `NotifyMoveFailure` precedent; the alternative of defaulting the harness's dispatcher was rejected earlier for the reason recorded at `TestSupport.cs` 162-167.

The observable ("any acquisition of the one-permit `TransactionGate` finds the permit held with no live holder"), its operationalisation as three counters and a balance test, the decision-rule table and the load condition were declared at P0-T11 (2026-09-13T02-36) before P1-T6/P1-T7 added the instrumentation; the declaration records zero `Interlocked.Increment` occurrences at the time of writing. +- (ii) PASS. Serial regime `acquisitions=11 releases=10 contended=0` (R4 excluded by filter, 1394 tests, `timeout=0`); parallel regime `19/18/14` (1395 tests, `timeout=0`); exact commands and load conditions recorded; confirmed unchanged in kind at P4-T3 (`11/10/0`, `19/18/14`). +- (iv) PASS. Six `ThroughThePumpHost` durations per regime (largest serial 124.5 ms; largest parallel 6,460.4 ms, a 58x elongation under class-level parallelism on an idle machine) with the arithmetic against the 60,000 ms bound and the recorded 6x-26x load multiplier. +- FAIL triggers not met: the artifact does not reason only from static reading; it names neither removed identifier outside the mandated quotation; it does not report agreement with both hypotheses. + +What the evidence does not establish: + +- (iii) PARTIAL. The artifact names the rejected hypothesis (H-LEAK) and gives an observation (`contended=0`, balance difference 1). But H-LEAK is defined in spec section 4.2 as a leak that occurs when MSTest stops observing a timed-out `async` test, so that its `finally` never releases the permit. In a run with zero expiries no test was abandoned, so no leak could occur whichever hypothesis is true; the serial observable therefore had only one value it could take, and observing that value is consistent with both hypotheses. A further structural point (code review, N-3): under H-LEAK the serial-regime signature would be the balance test blocking on `WaitAsync` and expiring under its own `[Timeout]` with no `GATECOUNTERS` line printed, so rows 2 and 3 of the decision-rule table cannot be observed as printed counter values; only row 1 can. The verdict's phrase "REJECTED by direct observation" overstates what was observed. +- No-expiry clause. Spec AC1's final sentence: "If the instrumented run produces no expiry at all, that is a recorded negative result, not a pass." The risk table (spec line 531): "A recorded negative result is an honest outcome, not a pass. Escalate rather than infer." The artifact records the negative result plainly (section "Expiry statement") and then infers. The plan's P1-T11 task text treated the negative result as something to state rather than as a bar to passing; the spec is the authority over the plan. + +What can be said in H-COST's favour on this evidence: H-LEAK cannot be an originating mechanism (it amplifies an initial expiry into a cluster), so the originating mechanism of any expiry is elapsed fixture cost by elimination within the spec's own two-hypothesis frame; the parallel-regime measurement shows that cost reaching 6,460 ms with no external load, and 6,460 ms times the upper recorded multiplier exceeds the bound. That is sufficiency evidence for H-COST as originator. It leaves the cascade question (spec unknown U2) open and untested, which is what the artifact should say. + +Verdict: PARTIAL. Resolution paths, cheapest first: (a) amend section (iii) of the verdict artifact to the wording above, record U2 as still open, and obtain the maintainer's explicit ratification that the negative result is accepted for AC1, transcribed into `issue.md` (a gitignored orchestrator-state note is not sufficient); or (b) an instrumented reproduction that produces an expiry, which the spec anticipates may be infeasible. The instrumentation code needs no change under either path. Per the check-off protocol, AC1 should be `- [ ]` until one path completes; this review did not edit `spec.md` (orchestrator directive). + +### AC2 — detailed evaluation, including the same-test question + +- The named test is cited as file path plus method name in the executor's acceptance-status artifact and in the plan's AC-MAPPING; the method exists at `SeamMarshallingTests.cs` lines 180-221. +- (i) Six outcomes transcribed: P2-T9 runs 1-3 on the defect-preserving intermediate (`bce810495`): `total=5 passed=2 failed=3` each, tests 1 and 2 `InvalidCastException`, test 5 `NullReferenceException`; P3-T6 runs 1-3 on the fixed tree (`cc236c8d2`): `5/5` each. Same machine, same session (2026-09-13T03-04 and T03-28). +- Deviation: between the two run sets the executor moved the ambient `SynchronizationContext` installation to after the WinForms control construction, because a `Control` constructor replaces an ambient context of exact type `SynchronizationContext` and the original order hung (first pass-after attempt: tests 1 and 2 `timed out after 60000ms`, recorded in `ac2-pass-after-three-runs`). Why the fail-before outcome is unaffected: the recorded exception type is the proof. An `InvalidCastException` naming `Castle.Proxies.IItemViewerProxy` can only come from the `(ItemViewer)itemViewer` cast P2-T3 placed in the argument expression of the first `CreateAsync` call, which C# evaluates before the call and therefore before the member's first `await`; the returned `Task` is faulted synchronously. Under the old arrangement, reaching an `await` would have produced a timeout (as it did on the fixed tree), not an exception. Test 5's `NullReferenceException` likewise arises from `_itemViewer.UiDispatcher.InvokeAsync` on a mock that returns null for the sealed `Dispatcher` type, before any await. The arrangement change only affects behaviour after the first await. Residual: the corrected file was never literally run against the intermediate, and the statement that the correction was confined to arrangement order could not be checked by diff in this review; a literal re-run is recommended, not required. +- (ii) PASS: `Select-String` over the seam file for `Thread\.Sleep|Task\.Delay|Stopwatch|DateTime\.Now|DateTime\.UtcNow|Environment\.TickCount|\bwhile\b` returned an empty match list, transcribed verbatim; confirmed by this review's own read of the file. +- (iii) PASS: `[Timeout(` count 5, one per test, all `SeamTimeoutMs`; no other time-valued construct. +- (iv) PASS: assertions are counts, non-emptiness, Moq interaction verifications and a reflection parameter-type check; none is an elapsed duration. +- Relation to AC1's mechanism: with H-COST operative, spec section 7.1 row 2 defines the regression test's form as "the member completes with a synchronous dispatcher and constructs no real viewer"; the named test is of that form. + +### AC3 — notes + +- (a) The structural zero-construction assertion `NotBeAssignableTo<ItemViewer>` is tautological for an interface Moq proxy (code review N-5); the effective proof that no concrete viewer is required is that the `await` completed on the fixed tree and faulted on the intermediate. Component (a) still PASSES as specified, because the spec asks for a structural assertion in one run and the run exists. Strengthening the assertion is recommended. +- (b) The targeted scope is the seam test class, which by construction never builds a real viewer, so the 62-run streak demonstrates that class's stability rather than the pump-hosted tests'. The spec defines the scope that way and labels the component supporting; PASS as specified. + +### AC4 — notes + +- The post-change coverage run recorded three environmental failures in `QfcInitEmailQueueZeroBatchTests` (Deedle `TypeInitializationException`); they are outside both subject files and the AC4 accounting is line-level for the subject file, so the verdict stands. Root `lines-covered` fell by 11 between the runs, plausibly for the same reason; not a changed-line regression. +- Branch rate was not transcribed (code review N-8); AC4 is phrased over line rate only. +- Component (v) was cross-checked by name: every test named in spec section 7.1 and 7.2 (five seam tests, the balance test, six gate tests, the Part3 initialization class including the five `ThroughThePumpHost` tests, the two seam-factory `Create*` tests, `ResolveControlGroupsAsync_ThroughThePumpHost_PopulatesTipsAndControlGroups`, eight breadcrumb-host tests, fourteen contract tests) appears with outcome `Passed` in `final-serial-test-run`. + +### AC5 — notes + +- The mirror artifact satisfies every content requirement of the evidence-and-timestamp skill; its filename combines two issues into one file rather than `issue-<N>.<timestamp>.md` (observation). +- The comment text is measured and does not describe the earlier refutation as wrong; it corrects the Designer line citation (6166-6167 to 6165-6166) and re-verifies the mechanics against the current tree. +- Live state not fetched: this review had no `gh`; the two comment URLs carry sequential comment ids (5652002368, 5652002536) consistent with two posts in the same minute. + +## Orchestrator-Requested Assessments (summary; full text in the code review) + +1.

Base SHAs are as supplied by the orchestrator; they were not recomputed in this review (see Reviewer constraints). +- **Work mode:** `full-bug` (`issue.md` line 12). AC source: `spec.md` `## Acceptance Criteria` (lines 409-488), five criteria. +- **Audit timestamp:** 2026-09-13T15-30 (the orchestrator receipt records the review dispatch at 2026-09-13T15-14; no clock is available to this review without a shell, so the timestamp is taken from that receipt plus elapsed reading time). +- **Reviewer constraints (recorded assumptions):** the launching agent's directive forbids the Bash tool for this run. Every observation below was made with Read, Grep and Glob against the item worktree. Consequences: (1) no `git` command was run, so the branch diff was taken from the orchestrator's verbatim name-status list and cross-checked against the executor's anchored diff audit (`evidence/qa-gates/final-write-set-audit.2026-09-12T19-30.md`) and the current file contents; (2) `validate_evidence_locations.py` and the coverage-hook simulation were not run; (3) no test, build or coverage command was executed — every toolchain and coverage figure is a transcription from the committed projection artifacts, read directly. Where a claim could not be checked with the read-only tools, the section says so and names the check the orchestrator should run. +- **Policy documents applied (read from the item worktree):** `CLAUDE.md`; `.claude/rules/general-code-change.md`; `.claude/rules/general-unit-test.md`; `.claude/rules/quality-tiers.md`; `.claude/rules/csharp.md`; `.claude/rules/tonality.md`; skills `policy-compliance-order`, `acceptance-criteria-tracking`, `evidence-and-timestamp-conventions`, `policy-audit-template-usage`, `feature-promotion-lifecycle` (user-story rule, line 111). +- **Template provenance deviation:** the MCP template asset (`mcp__drm-copilot__resolve_policy_audit_template_asset`) is not in this agent's tool surface for this run. The document is hand-authored preserving the twelve canonical major headings the `policy-audit-template-usage` skill enumerates, plus the `## Rejected Scope Narrowing` and `## Evidence Location Compliance` sections the feature-review contract requires. The document is not marked BLOCKED because every section is populated from evidence. + +## Executive Summary + +- **Verdict: REMEDIATION REQUIRED.** Two findings block acceptance; neither is a production-code defect. + 1. **Host-path leak (Blocking).** `evidence/other/orchestrator-citation-verification.2026-09-12T13-50.md` line 6 contains an absolute user-profile path with the operator's account name. The file is added by this branch (the whole feature folder is new versus `origin/main`). Rule: `.claude/agent-memory/_shared_no_absolute_host_paths.md` (applies to every committed artifact) and the plan's own gate-literal rule 4. Remedy: substitute `<repo-root>/.claude/worktrees/agent-a190dd2fffe21a25d` and squash-merge so the pre-sanitisation blob is not reachable from `main`. + 2. **AC1 evaluated PARTIAL (Blocking for acceptance, documentation-level remedy).** The AC1 verdict artifact reports `H-LEAK REJECTED by direct observation`, but the instrumented runs produced zero expiries, and H-LEAK as defined in spec section 4.2 is a cascade that follows an initial expiry. In a run with no expiry the counter observable cannot take any value other than the one recorded, so it does not discriminate. Spec AC1's final sentence states that a no-expiry run "is a recorded negative result, not a pass", and the spec risk table says "Escalate rather than infer". Details in `feature-audit.2026-09-13T15-30.md`, AC1. +- **Production change quality: PASS.** The seven Write Set files are exactly the seven files changed under `QuickFiler/` and `QuickFiler.Test/`. The interface widening is additive (`UiDispatcher` and `UiSyncContext` retained; contract tests pass), the parameter widening is source-compatible with both existing callers, and the single converted marshal forwards to the same `Dispatcher.InvokeAsync(Action)` primitive on the non-null path (`UtilitiesCS/Threading/WpfUiDispatcher.cs` lines 24-25 and 43, read directly). +- **Toolchain: PASS** on one clean pass (format rewrote nothing; check exit 0; analyzer Rebuild `0 Warning(s)` / `0 Error(s)`; nullable Rebuild `0 Warning(s)` / `0 Error(s)`; serial `QuickFiler.Test` run 1400/1400, baseline 1394/1394). All transcribed from `evidence/qa-gates/final-*.2026-09-12T19-30.md`. +- **C# coverage verdict: FAIL** (canonical `artifacts/csharp/coverage.xml` absent under the item's projections-only convention; the transcribed root line-rate of the single-assembly run is 24.15%, below the 85% floor; branch rate not transcribed). Disposition: non-blocking and procedural. The change-scope gates hold from the projections: modified file `QfcItemController.ViewerSetup.cs` 90.61% line (baseline 90.48%, no regression, +3 measurable lines all hit); `QfcItemController.Initialization.cs` 95.04% unchanged; the two production members added to `ItemViewer.cs` are unmeasurable because of the pre-existing type-level `[ExcludeFromCodeCoverage]` at line 20, and the two interface members have no bodies. +- **Non-blocking findings** are enumerated in section 8 and in `code-review.2026-09-13T15-30.md`. + +## Rejected Scope Narrowing + +The audit scope is the full branch diff against the resolved base. The launching prompt contains one instruction that narrows the file set, recorded verbatim: + +> `M .claude/agent-memory/** (6 modified index/memory files, 5 added memory files — tracked agent memory written by earlier sessions; out of review scope except for host-path hygiene)` + +Justification for rejecting it: the eleven agent-memory files are part of the branch diff and merge to `main` with the rest of the branch, so they are inside the audit scope. What this review could do about them without a shell: Grep over the item worktree's `.claude/agent-memory` tree for the user-profile prefix (drive letter plus the `Users` segment, both separator forms) and the account name returns 15 files (one occurrence each), listed in section 8. Whether any of those occurrences is introduced by this branch cannot be determined without the diff; the orchestrator should run the branch-scoped sweep named in section 8 before merge. No other narrowing instruction was found. The `DIRECTIVE: PREFLIGHT VALIDATION ONLY` line at the foot of the plan is planner-to-executor handoff text, not a scope instruction to this review. + +One further directive is recorded as a deviation from this agent's output contract rather than as narrowing: the launching prompt states "Write no other file", so `remediation-inputs.<timestamp>.md` was not written. The remediation-required findings are enumerated in the feature audit under `## Remediation-Required Findings` so that nothing is lost; the orchestrator should either author the remediation-inputs artifact from that section or re-dispatch this review with permission to write it. + +## Evidence Location Compliance + +- Canonical scheme: `<FEATURE>/evidence/<kind>/`. Glob over the feature folder shows every evidence artifact under `evidence/baseline/`, `evidence/regression-testing/`, `evidence/qa-gates/`, `evidence/issue-updates/` or `evidence/other/` (54 files enumerated). PASS. +- Forbidden paths: Glob `artifacts/**/*` over the item worktree returns only `artifacts/orchestration/orchestrator-state.json` (gitignored orchestration state) and six pre-existing `artifacts/pr_body_*` files that are not in this branch's diff. No file exists under `artifacts/baselines/`, `artifacts/baseline/`, `artifacts/qa/`, `artifacts/qa-gates/`, `artifacts/evidence/`, `artifacts/coverage/`, `artifacts/regression-testing/` or `artifacts/post-change/`. PASS. +- `validate_evidence_locations.py --root .` was not run (no shell); the Glob enumeration above is the substitute check. The orchestrator can run the script to confirm; a non-zero exit would add findings here. +- Projections-only convention (spec section 8, plan D1): `evidence/qa-gates/final-projections-only-audit.2026-09-12T19-30.md` records 570 tracked `*.trx`/`*.cobertura.xml` paths both at the self-anchor and at the final tree, and zero untracked or modified raw artifacts. The 570 pre-existing raw files are outside this item's scope. PASS for this item's additions. +- Issue-update mirror: `evidence/issue-updates/issue-511-and-571-reconciliation.2026-09-12T19-00.md` carries `Timestamp:`, the exact posted text, `PostedAs: comment` and both comment URLs. The filename does not follow the skill's `issue-<N>.<timestamp>.md` pattern (one combined file for two issues).

The root figure is a single-assembly run (`-SearchRoot QuickFiler.Test`), so its denominator includes every loaded first-party module while only QuickFiler tests executed; it is not comparable with the repository-wide figure the CI gate computes and it is expected to sit far below the floor. The last repository-wide figures known to this reviewer from prior reviews were approximately 84.8-85.3% line and approximately 79% branch; they were not re-measured on this branch. +2. Root `lines-covered` fell by 11 (14950 to 14939) between the two runs while ViewerSetup.cs gained 3 covered lines. The post-change run recorded three failed tests in `QfcInitEmailQueueZeroBatchTests` (Deedle `TypeInitializationException`, environmental, see section 8), which is the plausible cause of the movement in unrelated classes. It is not a changed-line regression: the AC4 artifact accounts every added ViewerSetup.cs line as hit. +3. Branch coverage is not transcribed in either projection. The only new branch in production code is `if (dispatcher is null)` in `AssignControlsAsync`; both arms are exercised (null arm by `AssignControlsAsync_DispatchesAssignThroughViewerDispatcher`, seam arm by `AssignControlsAsync_WithSyncDispatcherDouble_AssignsThroughTheInjectedSeam`), which is evidence of exercise, not a measured branch rate. + +## 2.

Gaps and Exceptions + +1. **Blocking — host-path leak.** `evidence/other/orchestrator-citation-verification.2026-09-12T13-50.md` line 6 carries a backticked absolute path of the form `<user-profile>/repos/TaskMaster/.claude/worktrees/agent-a190dd2fffe21a25d`, with the real user-profile prefix (drive letter, `Users` segment and account name) written out in the file; the raw value is deliberately not reproduced here. Rule: `.claude/agent-memory/_shared_no_absolute_host_paths.md` ("No file committed to this repository may contain an absolute host path or a host identifier"). Authored in the preparation session, added to `main` by this branch. Remedy: replace with `<repo-root>/.claude/worktrees/agent-a190dd2fffe21a25d`; squash-merge the branch so the original blob is unreachable from `main`. The executor disclosed this in its run-B receipt and declined repair on Write Set grounds; that scope lock binds the executor, not the branch. +2. **Blocking for acceptance — AC1 PARTIAL.** See the feature audit. Remedy options, in order of cost: (a) amend section (iii) of `evidence/baseline/ac1-mechanism-verdict.2026-09-12T17-00.md` to state that H-COST is the only available originating mechanism (H-LEAK is by definition a cascade that requires a prior expiry, and the spec's U2 remains open and untested), supported by the measured elongation figures, and obtain the maintainer's explicit ratification that the recorded negative result is accepted for AC1, transcribed into `issue.md`; or (b) design and run an instrumented reproduction that produces an expiry (the spec's risk table anticipates this may be infeasible and says to escalate). +3. **Non-blocking — C# coverage procedural FAIL** (section 1.2): canonical artifact absent by convention; single-assembly root figure below floor; branch rate not transcribed. No code change required. If the orchestrator needs the canonical artifact for the hook, the maintainer's projections-only decision (#671) conflicts with the artifact-path rule and should be reconciled at policy level rather than by committing raw XML. +4. **Non-blocking — AC2 arrangement-order deviation** between the fail-before and pass-after run sets (feature audit AC2). A literal re-run of the final seam-test text against the P2 intermediate (commit `bce810495` production files) would remove the residual reliance on reasoning; optional. +5. **Non-blocking — evidence timestamp convention.** Executor artifacts carry `Timestamp:` values 02-11 through 03-53 on 2026-09-13 while the orchestrator receipts for the same runs record 13-12 through 15-10; the offset is a consistent 12 hours. `phase0-diff-base` records a re-anchor addendum at `2026-09-13T13-05` that precedes P0-T4 (`02-11`) in the executor's convention. The artifacts remain internally ordered; the two clocks should not be mixed in one folder. Observation. +6. **Non-blocking — `user-story.md` present in a `full-bug` folder.** `feature-promotion-lifecycle` line 111: "For `full-bug`, `spec.md` is expected alongside `issue.md`; `user-story.md` should be absent unless the requirements explicitly justify it." The file self-justifies with "the feature-document contract requires both artifacts to exist", which is a contract citation rather than a requirements justification. It is explicitly marked non-authoritative and carries no checkboxes, so no AC-source ambiguity results. Severity: observation; the orchestrator may delete it at merge or leave it. +7. **Non-blocking — `.claude/agent-memory` host-path attribution.** Current-tree matches (one occurrence each): `_shared_no_absolute_host_paths.md`; `epic-planner/reference_isolated_worktrees_cut_from_main_not_session_head.md`; `feature-review/project_464-review-residuals.md`; `feature-review/project_565-review-residuals.md`; `feature-review/project_730-review-residuals.md`; `atomic-executor/project_bash_heredoc_collapses_doubled_backslashes.md`; `atomic-executor/project_koverage_reporoot_needs_native_separators.md`; `atomic-executor/project_selftest_probe_literal_trips_the_next_sweep_pass.md`; `atomic-planner/worktree-root-breaks-dotclaude-exclusion.md`; `orchestrator/angle-bracket-redaction-breaks-trx-xml.md`; `orchestrator/bash-tool-collapses-double-backslash-in-sed.md`; `orchestrator/collect-pr-context-lands-in-main-checkout.md`; `orchestrator/preparation-child-cwd-is-session-root-not-item-worktree.md`; `epic-orchestrator/feedback_measure_whole_volume_before_blaming_worktrees.md`; `epic-orchestrator/feedback_region_ownership_is_a_prefix_claim.md`. Several of these are the hygiene rule's own examples. Required check before merge: `git diff origin/main...HEAD -- .claude/agent-memory | grep -i -E "^\+.*(<account>|C:[\\/]Users)"`; any hit is a Blocking finding of the same class as item 1. +8. **Out-of-scope defects reported by the executors (follow-ups, not findings against this item):** (a) Meziantou.Analyzer HintPath skew — `UtilitiesCS/UtilitiesCS.csproj` line 1308 and `VBFunctions/VBFunctions.csproj` line 58 name `Meziantou.Analyzer.3.0.203` while lines 3/1300 and 3/73 of the same files and both `packages.config` files name `3.0.235` (confirmed by Grep in this review); a cold restore fails with CS0006 until `3.0.203` is installed manually; pre-dates the branch; promote to an issue. (b) `QfcInitEmailQueueZeroBatchTests` fails intermittently under class-level parallelism with `TypeInitializationException` (`Deedle.Reflection`, `netstandard 2.1.0.0` binding) and passes serially and on re-run (two occurrences recorded: P4-T3 run B, P6-T6); promote to an issue. +9. **Reviewer tooling gaps (recorded, not findings):** no `git` recomputation of the merge-base; no coverage-hook simulation; `validate_evidence_locations.py` not run; the live GitHub comments for AC5 not fetched.

Also append the reviewer's structural point (code-review N-3): under H-LEAK the serial-regime signature is the balance test blocking on `WaitAsync` and expiring under its own `[Timeout]` with no `GATECOUNTERS` line printed, so decision-rule rows 2 and 3 cannot be observed as printed counter values and row 1 is the only row observable as a printed triple. +- Same N-3 addendum, dated, appended to `evidence/baseline/ac1-serial-measurement.2026-09-12T17-00.md` (after its decision-rule table).

The original blob stays reachable in history; squash merges are disallowed repository-wide, so purging it would mean rewriting a pushed branch, which the maintainer judged more dangerous than the residual. The residual is to be disclosed in the pull-request body. AC1: the feature review rated AC1 PARTIAL, so the checked box on disk was wrong. Unchecked per maintainer ruling, independently of the remediation task that would otherwise have done it. R-2, the wording amendment plus manual ratification of the AC1 negative result, remains open with the maintainer.

All four are discharged here. The ratification accepts the item despite a negative result; it is not a finding that the result was positive, and AC1's checkbox stays unchecked because the checkbox records what was measured. Condition 1: AC1 verified still unchecked in spec.md (one match for the unchecked form, zero for the checked form; AC2-AC5 unchanged). Condition 2: the AC1 mechanism verdict is corrected a second time. The original Output Summary claimed H-LEAK was rejected by direct observation of the pre-declared counter observable, and the first amendment then claimed that rejection rested on the counter observable and that this was a legitimate basis. Both claims are withdrawn and both superseded texts are retained under a Correction history heading, so a reader can see both corrections. The accurate statement is that both runs recorded timeout=0, no expiry occurred, and therefore neither H-COST nor H-LEAK was discriminated: there was no expiry event in which to observe whether the one-permit gate was held with no live holder. A hypothesis cannot be rejected by the absence of observations. With no expiry no test was abandoned, so under the spec's own definition of H-LEAK as a cascade conditional on a prior expiry the contended=0 reading was predetermined and carries no information about the hypothesis. Section (iii) is marked superseded rather than deleted, and the escalation paragraph now records that the maintainer has ruled. Condition 3: the AC3(b) statistical caveat is completed in the preparation-mode derivation artifact, which carried the qualitative uncertainty language but neither the single-failure provenance nor the interval. The acceptance-governing artifact ac3b-consecutive-runs already carried both, as spec AC3 requires. Both Clopper-Pearson endpoints were re-derived rather than copied: lower 0.0012049, upper 0.2382. The consequence is stated plainly - near the low endpoint, 62 clean runs establish little. Condition 4: issue 882 is filed for the H-LEAK question through the MCP promotion lifecycle, with no active feature folder.

Also corrects the acceptance-status artifact, which still read PASS for AC1 after commit 9170499b4 unchecked the box without updating it, and redacts the operator account name from a command string in the cycle-1 remediation inputs - the same defect class as R-1, in the document that scoped R-1's repair.

No expiry was observed in either instrumented run. + +Why both superseded texts are wrong. Section 4.2 of `spec.md` defines H-LEAK as a leak that FOLLOWS a timed-out `async` test whose `finally` MSTest has stopped observing. H-LEAK is therefore conditional on an expiry having already occurred. Both instrumented runs recorded `timeout=0`, so no test was abandoned, so under EITHER hypothesis no leak could have occurred in these runs. The serial reading `contended=0` was consequently PREDETERMINED by the absence of expiry: it would have read zero whether H-LEAK is true of this codebase or false. A reading that is fixed in advance by a condition independent of the hypothesis carries no information about the hypothesis, so it cannot reject it. The counter observable was declared in advance and was measured honestly; what failed is that the run never entered the regime in which the observable becomes discriminating. + +The correct statement of what these runs establish: no expiry was reproduced, so the discriminating experiment did not take place. H-COST remains the only available ORIGINATING mechanism within the spec's two-hypothesis frame, because H-LEAK is a cascade conditional on an initial expiry rather than an originating cause; the sufficiency evidence for H-COST is the measured parallel-regime elongation in section (iv). That is a narrower claim than "H-LEAK is rejected". H-LEAK IS NOT REJECTED. Spec unknown U2 — whether a first expiry cascades through a leaked permit — remains OPEN and UNTESTED by this item. It is carried forward as a separate issue; see the ratification record at `evidence/other/maintainer-ratification-ac1.2026-09-13T18-00.md`. + +CONSEQUENCE FOR AC1, STATED EXPLICITLY SO IT IS NOT INFERRED EITHER WAY.

Its conclusion "H-LEAK REJECTED by direct observation" is the claim Correction 2 withdraws. Read it as a record of what was claimed on 2026-09-13, not as a finding. Two specific sentences below do not survive: "A serial run cannot queue a second live holder; therefore a contended count of zero in that regime is a direct observation that the permit was never found held by a leaked transaction" is unsound because with `timeout=0` no transaction could have leaked under either hypothesis, so the zero was predetermined; and "The two hypotheses are not both supported; only H-COST survives" overstates a result that discriminated neither. + +A further structural point, from the code review (finding N-3), explains why the decision rule could not have discriminated as written: under H-LEAK the serial-regime signature is the balance test BLOCKING on `WaitAsync` and expiring under its own `[Timeout]` with no `GATECOUNTERS` line printed at all. Rows 2 and 3 of the rule are therefore not observable as printed counter values. Row 1 is the only row that can ever appear as a printed triple, so selecting row 1 is not evidence that rows 2 and 3 were ruled out.

The other four criteria remain `- [x]`. The stale `evidence/other/acceptance-status.2026-09-12T19-30.md` row that still read `PASS` for AC1 — a residual of commit 9170499b4, which unchecked the box in `spec.md` without updating that artifact — has been corrected to `RATIFIED NEGATIVE RESULT — NOT A PASS`, with the superseded summary retained. + +### Condition 2 — the verdict wording is corrected, with both prior errors visible + +**Discharged** in `evidence/baseline/ac1-mechanism-verdict.2026-09-12T17-00.md`.

The accurate statement now recorded is that the instrumented runs recorded `timeout=0`, no expiry occurred, and therefore **neither H-COST nor H-LEAK was discriminated**: there was no expiry event in which to observe whether the one-permit `TransactionGate` was held with no live holder. **A hypothesis cannot be rejected by the absence of observations.** + +The mechanism of the error is recorded in the artifact and is worth restating. Section 4.2 of `spec.md` defines H-LEAK as a cascade conditional on a prior expiry. With `timeout=0`, no test was abandoned, so no leak could have occurred under *either* hypothesis. The pre-declared observable therefore read `contended=0` for a reason wholly independent of whether H-LEAK is true of this codebase. The reading was predetermined, and a predetermined reading carries no information about the hypothesis it was declared to test. The observable was declared honestly and in advance; what failed is that the run never entered the regime in which it becomes discriminating. + +Section (iii) of the verdict artifact is marked SUPERSEDED rather than deleted, and the escalation paragraph has been updated from "escalated and unresolved" to record that the maintainer has now ruled. + +### Condition 3 — the AC3(b) statistical caveat is complete + +**Discharged.** State before this run, reported precisely because the two artifacts differed: + +- `evidence/regression-testing/ac3b-consecutive-runs.2026-09-12T19-00.md`, which is the artifact spec AC3(b) governs and whose content AC3's own text mandates: **PRESENT and complete.** Its line 25 already carried both the single-failure provenance and the interval. +- `evidence/other/orchestrator-run-count-derivation.2026-09-12T14-15.md`, the preparation-mode derivation: **PARTIAL.** Its Sensitivity note carried the qualitative wide-uncertainty language but neither the single-failure provenance nor the interval. + +The derivation artifact has been completed.

Issue 743 set out to discriminate this hypothesis (H-LEAK) from elapsed fixture cost (H-COST) by instrumented measurement, and the measurement did not discriminate them: no expiry occurred in either instrumented run, so the discriminating experiment never took place. H-LEAK was never excluded, only never observed. Issue 743's fix routes the affected tests around the gate via a UI-marshalling seam rather than answering the question, so if H-LEAK is the real mechanism the defect still exists behind the seam. This issue carries that open question forward so it is not retired along with 743's symptom. + +## Environment + +- OS/version: Windows 11 Pro 10.0.26200 (the machine on which issue 743's instrumented runs were taken) +- Python version: not applicable; this is a C# / .NET Framework 4.8 defect +- Command/flags used: `vstest.console.exe QuickFiler.Test\bin\Debug\QuickFiler.Test.dll /InIsolation "/TestCaseFilter:TestCategory!=LiveOutlook"` for the SERIAL regime, and the same command with `/Settings:TaskMaster.runsettings` (Workers 0, Scope ClassLevel) for the PARALLEL regime +- Data source or fixture: `QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs` — the `UiThreadDispatcherFixture` / `UiThreadDispatcherTransaction` pair, whose `TransactionGate` is the subject + +## Steps to Reproduce + +1. Read `QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs` and confirm the current shape of `TransactionGate`: a `SemaphoreSlim(1, 1)` acquired by `BeginTransactionAsync` and released by `ReleaseTransactionGate` from the transaction's `Dispose`. +2. Observe that the acquisition is awaited with no timeout argument and no `CancellationToken` overload, so a caller that finds the permit held waits without bound. +3. Construct the state the hypothesis requires: an `async` test that acquires a transaction and then exceeds its MSTest `[Timeout(...)]` bound before reaching the `Dispose` that releases the permit. MSTest abandons a timed-out `async` test rather than unwinding it, so the `finally` that would release the permit is no longer observed. +4. Run any later test in the same assembly that acquires the gate. +5. The open question is whether step 4 then blocks without bound on a permit no live holder owns. This has NOT been demonstrated, and demonstrating or refuting it is the work of this issue. + +## Expected Behavior + +A one-permit gate either releases its permit on every path out of a transaction, including abandonment of a timed-out `async` test, or it acquires with a bounded timeout so that a lost permit surfaces as a prompt, diagnosable failure rather than an unbounded wait. A later test must not be able to block indefinitely because an earlier test was abandoned. + +## Actual Behavior + +Unknown, and that is the defect being filed. Issue 743's instrumented measurement was designed to settle it and did not. Both instrumented runs recorded `timeout=0` — no test was abandoned in either run. Because H-LEAK is by definition a cascade conditional on a prior expiry, the absence of any expiry meant no leak could have occurred under either hypothesis, so the pre-declared observable (`contended`, the count of acquisitions that find the permit held) read zero for a reason entirely independent of whether H-LEAK is true of this codebase. The serial reading `acquisitions=11 releases=10 contended=0` was predetermined by the absence of expiry and carries no information about the hypothesis. + +**A hypothesis cannot be rejected by the absence of observations.** Issue 743's verdict artifact originally claimed H-LEAK was "REJECTED by direct observation", and a first amendment then claimed the rejection "rests entirely on the counter observable, which is a legitimate basis". Both claims were wrong and both have been withdrawn on the 743 branch; the artifact now records that neither hypothesis was discriminated. See `docs/features/active/2026-09-02-quickfiler-itemviewer-ui-marshalling-seam-743/evidence/baseline/ac1-mechanism-verdict.2026-09-12T17-00.md`, Correction 2. + +## Logs / Screenshots + +- [x] Attached minimal logs or screenshot +- Snippet: instrumented `GATECOUNTERS` triples from issue 743, both taken on 2026-09-13 from the same instrumented assembly on an otherwise-idle machine with Outlook closed: + - SERIAL regime, 1394 tests: `acquisitions=11 releases=10 contended=0`, balance test passed with difference exactly 1, `timeout=0`, `failed=0`. + - PARALLEL regime (Workers 0, Scope ClassLevel), 1395 tests: `acquisitions=19 releases=18 contended=14`, balance test passed with difference exactly 1, `timeout=0`, `failed=0`. + - The 14 contended acquisitions in the parallel regime are live-holder queueing by distinct test classes, not leaks; the balance test confirms it.

Medium rather than Low because an unbounded wait on a lost permit presents as a hung or timed-out test run whose cause is not local to the failing test, which is expensive to diagnose and is a plausible contributor to the historical flake rate recorded in issues 592, 511 and 571 that 743 was opened to address. + +## Suspected Cause / Notes + +The load-bearing evidence is correction C2 of issue 743's spec, verified against the current tree before this issue was filed. C2 states: + +> **C2 — #493 changed the owner of the serialization, not its shape.** `TransactionGate` is still a one-permit `SemaphoreSlim(1,1)`, still awaited without timeout or cancellation token, and still held from acquisition to disposal. The lead must therefore be re-tested against the current gate, not assumed closed and not assumed open. + +The significance is that issue 493 is frequently cited as having closed this area. It did not. It moved the ownership of the serialization; the gate's shape — one permit, unbounded wait, held for the full span from acquisition to disposal — is unchanged, and every precondition the leak hypothesis needs is still present. Correction C1 of the same spec is also relevant to anyone searching: the identifiers `UiThreadDispatcherGate` and `SwapUiThreadDispatcher` appear in **zero** `.cs` files in the current tree, so a search on those names returns nothing and must not be read as evidence that the mechanism is gone. The live identifiers are `UiThreadDispatcherFixture` and `UiThreadDispatcherTransaction`. + +Spec unknown U2 of issue 743 — whether a first expiry cascades through a leaked permit — is the precise question, and 743 records it as OPEN and UNTESTED. + +**Why this issue must exist rather than being closed inside 743.** Issue 743's remedy is a UI-marshalling seam that routes the affected tests around the concrete viewer and the pump-hosted fixture. That removes the affected tests from the path where the gate is contended. It does not change the gate. If the originating mechanism was H-LEAK, the defect is still present and the seam has AVOIDED it rather than FIXED it. Closing 743 without this issue would retire the observable symptom and lose the open question with it. This is the same disposition applied to the Deedle production risk in issue 879: promote the unresolved part rather than let it close silently inside a merged item. + +## Proposed Fix / Validation Ideas + +- [x] Unit coverage areas: `QuickFiler.Test/Controllers/QfcItemController.UiThreadDispatcherFixture.cs` and its existing test file `QfcItemController.UiThreadDispatcherFixtureTests.cs`. A test that deliberately abandons a transaction-holding `async` test and then asserts the observable state of the gate is the direct experiment 743 could not run, because 743's instrumented runs produced no expiry to observe. +- [x] Integration scenario to retest: a full `QuickFiler.Test` run in the PARALLEL regime (`/Settings:TaskMaster.runsettings`, Workers 0, Scope ClassLevel), which is the regime in which the gate is genuinely contended (14 contended acquisitions observed) and therefore the regime in which a lost permit would be reachable. +- [x] Manual verification notes: two candidate remedies are worth evaluating and they are not equivalent. (1) Acquire with a bounded timeout or a `CancellationToken`, so a lost permit surfaces as a prompt, attributable failure instead of an unbounded wait — this makes the defect diagnosable but does not prevent the leak. (2) Guarantee release on abandonment, so the permit cannot be lost in the first place. Prefer (2) where it is achievable and treat (1) as a diagnostic backstop rather than the fix. +- **Trap to avoid, stated here because the reader will not have 743's feature folder.** Do not treat a clean run as evidence of absence. A run in which `timeout=0` cannot discriminate this hypothesis at all, for exactly the reason recorded under Actual Behavior above: with no expiry there is no abandonment, and with no abandonment there is no leak under either hypothesis, so the counters read identically whether the defect exists or not. Any verification of this issue must first establish that an expiry actually occurred, and only then read the gate state. A verification artifact that reports a clean run and concludes "no leak" repeats the precise error that 743's verdict artifact had to be corrected for twice. + +## Next Step + +- [x] Promote to GitHub issue (bug-report template) +- [ ] Move to active fix folder / branch + +Cross-reference: this issue originates from **issue 743** (QuickFiler ItemViewer UI-marshalling seam), whose maintainer ratification of the AC1 negative result on 2026-09-13 was granted on the explicit condition that this issue be filed before 743's pull request merges.

Neither H-COST nor H-LEAK was discriminated: the instrumented runs recorded timeout=0, so no expiry occurred and there was no event in which to observe whether the one-permit TransactionGate was held with no live holder. A hypothesis cannot be rejected by the absence of observations. Both prior texts are retained verbatim under a correction history, including a coordinator amendment that defended the wrong claim and is now explicitly withdrawn. AC1 remains UNCHECKED and is recorded as a ratified negative result rather than a pass. The checkbox records what was measured; the ratification records the maintainer accepting the item anyway. Adds the post-merge toolchain evidence and a conformance assessment against the Committed Test Evidence Format policy that landed on main after this branch base. Committed by the parallel-orchestrator coordinator: the item child was denied git add by the pre-implementation gate, which resolves its checkpoint path against the session worktree where a sibling item state was published.
