The test asserts `IsCompleted` is `false`, and it is recorded failing against the unmodified source before the fix is applied. +- [ ] AC2 (#889): The dispatcher exit in `UtilitiesCS/Threading/UiThread.cs` requires `_dispatcher is not null` before the dispatcher reference comparison, matching the guard the captured-context exit already carries. The AC1 test passes after the fix, and every pre-existing `IsCompleted` test in the UtilitiesCS.Test project still passes. +- [ ] AC3 (#863): `ILGlobals` in the SDIL Reader directory of UtilitiesCS no longer declares the `modules` field, and no longer exposes `Cache` as a public mutable static field (it is removed, or made private readonly). A repository-wide search confirms no remaining reference to either member, including by reflection or by string name, other than any retained private declaration. +- [ ] AC4 (#863): The `ILGlobals.Cache` assertion in `UtilitiesCS.Test/NewtonsoftHelpers/SDILReader/ILGlobals_Tests.cs` is updated or removed consistently with AC3, and the ILGlobals test class passes. +- [ ] AC5 (#862): The XML doc comments in `QuickFiler/Viewers/BreadcrumbBridgeCoordinator.Search.cs` and `QuickFiler/Viewers/BreadcrumbItemViewerLifecycleCoordinator.Search.cs` state no numeric line count for their primary partial-class file, while still explaining why the partial part exists. +- [ ] AC6: The full C# toolchain passes in one clean pass in CLAUDE.md order (CSharpier check, analyzer Rebuild, TreatWarningsAsErrors Rebuild, MSTest with coverage), with test execution in the existing parallel regime: no new `DoNotParallelize` attribute, no worker-count reduction, and no retry.

Never `cd`. Every command is written to run with the current directory at that root; the shell resets its cwd between calls, so each call already starts there. +- Bash discipline: the allowlist grants git, gh, pwsh and poetry run, and every chained segment of a command line is checked independently.

The captured-context exit (lines 182 to 192) requires `_dispatcher is not null` before comparing the thread's dispatcher to the captured one, with a comment at lines 175 to 181 explaining why. The dispatcher exit (lines 197 to 201) performs the same `ReferenceEquals(System.Windows.Threading.Dispatcher.FromThread(Thread.CurrentThread), _dispatcher)` comparison with no null test, so when no dispatcher was captured and the executing thread owns none, null equals null and the exit returns true. Remedy: insert the operand `&& _dispatcher is not null` between the type test and the reference comparison, and extend the comment above the exit by one line. Regression test first ([P1-T1], [P1-T3]), fix second ([P1-T4]). +2. #863 (ILGlobals.cs in the SDIL Reader directory of UtilitiesCS/NewtonsoftHelpers). Line 113 declares `public static Dictionary Cache = new Dictionary();` and line 131 declares `public static Module[]? modules = null;`. Re-derived: the only reference to either member anywhere in the tree outside documentation and the governance tree is the assertion `ILGlobals.Cache.Should().NotBeNull();` at line 267 of the test file; no production code reads, writes, reflects on or names either field.

Remedy: delete the parenthesised count token from each line and nothing else, so the sentence still says the part exists to keep the primary file clear of the 500-line ceiling ([P1-T14]). No behavioural test is possible for a comment edit; the gate is a token census (2 before, 0 after) plus a retention census of the explanation. The bridge coordinator has a third partial part whose remarks carry a historical sentence describing a past line count; that file is out of scope for issue 930 and is not edited, and [P1-T14] proves it by requiring the anchored numstat over the QuickFiler viewers directory to list exactly the two Search parts. -**Phase 5 — Documentation & Status** -- [ ] [P5-T1] Update spec/issue with outcomes, decisions, and any deviations from scope +## Write Set -**Phase 6 — PR & Handoff** -- [ ] [P6-T1] Prepare PR notes (summary, risks, validation performed, links to tests) and request review +- `UtilitiesCS/Threading/UiThread.cs` +- `UtilitiesCS/NewtonsoftHelpers/SDIL Reader/ILGlobals.cs` +- `QuickFiler/Viewers/BreadcrumbBridgeCoordinator.Search.cs` +- `QuickFiler/Viewers/BreadcrumbItemViewerLifecycleCoordinator.Search.cs` +- `UtilitiesCS.Test/Threading/UiThreadApartmentMeasurement_Tests.cs` +- `UtilitiesCS.Test/NewtonsoftHelpers/SDILReader/ILGlobals_Tests.cs` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/issue.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/plan.2026-09-28T20-01.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/baseline/` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/regression-testing/` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/` -**Phase 7 — Rollout / Follow-up** -- [ ] [P7-T1] Capture deployment/rollout notes and post-fix monitoring items -- [ ] [P7-T2] Record links (issue, PRs, related docs) for traceability +The second entry above contains a space in its directory name (the directory is named SDIL Reader).

[P0-T2] records `git rev-parse HEAD` before any edit as `BASE-SHA:`; every later command span writes BASE for that 40-character literal and the artifact's `Command:` field records the substituted command. A fixed commit literal is not pinned in this plan because the branch head moves with every documentation commit. +- D2 (formatter at baseline is read-only). Phase 0 runs the read-only `check` form only. A write-mode format at baseline would repair pre-existing drift outside this item's footprint and blur the anchored diff. The drift list [P0-T9] records is the comparison basis for [P2-T2]. If [P0-T9] lists any unformatted path, Phase 0 halts BLOCKED (the repository owns that repair; CI's format-check would already be red). +- D3 (coverage instrument). Baseline and final coverage both run the repository runner scripts/vscode/Invoke-MSTestWithCoverage.ps1 through its entry function after dot-sourcing (the script's entry guard skips the top-level call when dot-sourced), with one function replaced: `Get-DotnetCoverageArgumentList` is redefined to return the runner's own argument list plus four `FullyQualifiedName!~` exclusions and a `/Blame` hang collector. Reason: the four excluded UtilitiesCS.Test classes call the Windows shell icon API, which hangs process-wide on this workstation (measured on main by the operator on 2026-09-04, reproduced identically in a detached worktree); the runner hard-codes its filter and has no timeout, so an unmodified run stalls with no bounded failure. The exclusion is identical for baseline and final, so both figures describe the same test population, and every other runner step (discovery, derived settings, post-processing, 80 percent line and 75 percent branch assertions on the first-party document, first-party summary line, JaCoCo projection with reconciliation, trx summary, raw-document retention) executes verbatim. The four classes run unfiltered in the repository's mstest-coverage workflow on every pull request. The `/Blame` collector names any hanging test and writes a Sequence document; [P0-T12] and [P2-T6] gate on zero Sequence documents. Repository-wide figures are recorded and compared under Decision D10; the blocking coverage gates are per-file and per-changed-line. +- D4 (#863 disposition). Both fields are deleted rather than made private readonly. `Cache` has no reader in production or test code other than the not-null assertion, so a retained private readonly dictionary would be dead state that nothing publishes or consumes; `modules` has zero references. Repository guidance for dead code is removal, not exclusion. The `Cache_IsInitialized` test is deleted with the field and replaced by two structural tests that pin the property Expected Behavior 2 states (no public mutable static): `PublicStaticFields_AreAllInitOnly` and `PublicStaticFields_AreExactlyTheTwoOpCodeTables`. Both fail on the unfixed tree (the two public writable fields exist) and pass after the deletion, so the test class keeps a discriminating named assertion; the class grows from 14 to 15 test methods. +- D5 (#862 edit shape). Exactly one line changes per file: the token ` (487 lines)` is removed from line 11 of the bridge coordinator part and the token ` (481 lines)` from line 10 of the lifecycle coordinator part. No other wording changes, so the sentence still explains why the part exists. CSharpier does not reflow comments, so the edit is format-stable. The third bridge-coordinator partial part is not edited (Objective item 3). +- D6 (intermediate builds). [P1-T2], [P1-T5], [P1-T8] and [P1-T11] compile with the Build target because vstest never compiles and their only purpose is to produce the assembly the next scoped run reads; the scoped run is self-proving (a run reporting the new test's name proves it was compiled). Every diagnostic gate uses Rebuild and never passes the solution-wide Nullable property. The minimal console verbosity and detailed file-logger switches are logging-only additions; the `Task "Csc"` count from the detailed log is the non-vacuity observation for a Rebuild. +- D7 (committed evidence form). Coverage evidence committed under EVIDENCE is the runner's JaCoCo package projection file plus its one-line first-party summary; test-run evidence is the runner's trx-derived summary text or a summary transcribed from CMD-TRX-SUMMARY output. No .trx, .coverage, .cobertura.xml or msbuild log is copied into the feature folder. Raw documents stay under the coverage directory, which .gitignore line 144 excludes (line 145 re-includes only its .gitkeep). +- D8 (commits and inherited residue). Commit tasks: [P0-T15] (Phase 0 evidence, exempt form), [P1-T16] (implementation, source-bearing), [P2-T12] (QA evidence, exempt form), [P2-T21] (terminal, exempt form). Staging is always by explicit pathspec; `git add -A` is never used. Every porcelain gate asserts SCOPE, never emptiness or a count: any path under the feature folder or under .claude/agent-memory/ is admitted by rule, because agents write memory during the run and the plan file's own check-off marks land after each commit. The [P0-T2] porcelain snapshot is recorded as `PreExistingWorktreePaths:` and admitted by rule wherever it is outside the Write Set. +- D9 (fixed artifact names). Artifact filenames carry no timestamp segment so acceptance conditions can name them; the write time is the `Timestamp:` field. +- D10 (repository-wide coverage comparison). The first-party summary line's lines-valid figure is compared between baseline and final. Branch A (the two lines-valid figures differ by at most 1 percent of the baseline figure): the first-party line percentage must not fall by more than 0.5 percentage points and the branch percentage must not fall by more than 0.5 percentage points. Branch B (they differ by more): the figures are recorded and not gated, and the artifact says so in one sentence. Exactly one branch is named. The hard, unbranched gates are per file: UiThread.cs uncovered-line count not above baseline and every changed executable line hit; ILGlobals.cs uncovered-line count not above baseline (its diff is deletions only). +- D11 (green vstest console output). A passing vstest run prints `Test Run Successful.`, `Total tests:` and `Passed:` and prints neither a `Failed:` nor a `Skipped:` line. Counts are therefore read from the TRX through the repository's Get-TrxRunSummary reader (CMD-TRX-SUMMARY), which derives skipped as total minus executed and says so. +- D12 (test placement and concurrency regime). The #889 test is added to the existing `UiThreadPredicateHardening_Tests` class, which already carries `[DoNotParallelize]` (line 22) because it installs process-global UiThread statics through the shared scope, which is documented as not internally synchronized. Adding a method there adds no new attribute and no new serialization. The #863 tests are added to `ILGlobals_Tests`, which carries no such attribute and gains none. No worker-count change, no retry, no sleep, no delay and no temporary file is introduced; [P2-T9] gates all of these. +- D13 (halting). Phase 0 halts, without editing anything, on: Outlook running after the user has been asked to close it; the branch check failing; a red baseline (csharpier check drift, either Rebuild exiting non-zero or a non-zero `Error(s)` summary, the coverage runner throwing, or any failed test in the baseline scoped runs); a pre-implementation checkpoint missing the keys [P0-T3] names. A red baseline makes AC6 unsatisfiable by this plan, so the executor reports BLOCKED with the artifact and stops. Bounded exception: the full coverage run is documented as load-flaky on this workstation (one known sporadic failure, `TryAddValuesAsync_UpdatesExistingValue`, issue #780); a first run that fails only on that named test may be repeated exactly once with no intervening file change, both runs recorded with their own timestamps and the repeat identified as a repeat, not as a loop restart. + +## Regression test sources (copied verbatim by [P1-T1] and [P1-T7]) + +Indentation is eight spaces for class members, as in both files; the fences are not part of the content. + +#### [P1-T1] method, inserted into `UiThreadPredicateHardening_Tests` after line 96 (the closing brace of the second existing test), preceded by one blank line + +```csharp + /// + /// Issue #889: the dispatcher exit.

Acceptance: `RUNNER_RESULT=COMPLETED` (which implies the runner's own 80 percent line and 75 percent branch first-party assertions passed and the projection reconciled), `COBERTURA_EXISTS=True`, `PROJECTION_EXISTS=True`, `SUMMARY_EXISTS=True`, `SEQUENCE_FILES=0`, `Test run outcome: Completed` with failed 0 (Decision D13 repeat rule applies to the one named flaky test; a second failure of any test restarts the loop after a fix, never with a retry switch), the summary's `Total` equals `BASELINE-SUITE-TOTAL:` from [P0-T12] plus 2 (one #889 test plus one net #863 test: two added, one deleted), and CMD-TRX-NAMES with STAGE = final (its output appended to this artifact) prints `COUNT=1 OUTCOME=Passed` for the three new names and for all twelve pre-existing `IsCompleted` names and `COUNT=0 OUTCOME=absent` for `Cache_IsInitialized` (confirming [P1-T6] and [P1-T12], which are the measured runs; disagreement is recorded as a failure of this task), `RETURN_LINE_MATCHES=1`, `GUARD_COUNT=2`. +- [ ] [P2-T7] Coverage comparison, baseline versus post-change versus changed lines.

Acceptance (all unbranched except the first-party pair): `UITHREAD-UNCOVERED` final at most baseline; `ILGLOBALS-UNCOVERED` final at most baseline; final return-line `HITS` at least 1; guard-line `HITS` at least 1 or no line element; if `BASELINE-RETURN-COND` was a condition-coverage value then `FINAL-RETURN-COND` has covered equal to total (the new test covers the null outcome, the owning-thread test the true outcome, the different-dispatcher test the false reference outcome), otherwise the field is recorded with the sentence that condition coverage was not reported for that line; under Branch A the first-party line and branch percentages each fall by at most 0.5 points, under Branch B they are recorded and the artifact says the denominators are not comparable; exactly one branch is named. +- [ ] [P2-T8] Loop closure: write EVIDENCE/qa-gates/toolchain-final-pass.md listing, for the latest iteration, the six step artifacts with their `Timestamp:`, `EXIT_CODE:` and `Iteration:` values, `LOOP-ITERATIONS:` (the count of iterations run), `SOURCE-REWRITE-COMMITS:` (the SHAs of any style commits made under the loop rule, or NONE), and `LOOP: CLEAN PASS` only when every one of [P2-T1] through [P2-T6] met its acceptance in that same iteration and [P2-T1] rewrote nothing in it.

Artifact EVIDENCE/qa-gates/footprint.md. Acceptance: the first command lists exactly the six Write Set code paths (the space-bearing path prints quoted by git) and nothing else; the second prints nothing; every porcelain line names a path under the feature folder or under .claude/agent-memory/ (recorded verbatim; emptiness is not asserted, count is not recorded). +- [ ] [P2-T11] Evidence hygiene and committed-format gate: CMD-SANITIZE with LOGSTAGE = final and BASE substituted, then `pwsh -NoProfile -Command 'foreach ($p in "docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/baseline/baseline-coverage.jacoco.xml", "docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/final-coverage.jacoco.xml") { [xml]$x = Get-Content -LiteralPath $p -Raw; "PARSE_OK $p PACKAGES=$(@($x.report.package).Count)" }'`.

Acceptance: the artifact exists with every field; the `TOTAL:` figure equals the count of `- [x] AC` lines the Grep tool finds in issue.md; the reduced audit reads this artifact, the seven check-off lines and the four committed tool projections and nothing outside EVIDENCE. +- [ ] [P2-T21] Terminal commit in the exempt form: `git add -- docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930` then `git commit -m "docs(930): acceptance check-off and reduced-audit handoff" -- docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930`, then `git status --porcelain` and `git rev-parse HEAD`.

[P0-T2] records `git rev-parse HEAD` before any edit as `BASE-SHA:`; every later command span writes BASE for that 40-character literal and the artifact's `Command:` field records the substituted command. A fixed commit literal is not pinned in this plan because the branch head moves with every documentation commit. - D2 (formatter at baseline is read-only). Phase 0 runs the read-only `check` form only. A write-mode format at baseline would repair pre-existing drift outside this item's footprint and blur the anchored diff. The drift list [P0-T9] records is the comparison basis for [P2-T2]. If [P0-T9] lists any unformatted path, Phase 0 halts BLOCKED (the repository owns that repair; CI's format-check would already be red). -- D3 (coverage instrument). Baseline and final coverage both run the repository runner scripts/vscode/Invoke-MSTestWithCoverage.ps1 through its entry function after dot-sourcing (the script's entry guard skips the top-level call when dot-sourced), with one function replaced: `Get-DotnetCoverageArgumentList` is redefined to return the runner's own argument list plus four `FullyQualifiedName!~` exclusions and a `/Blame` hang collector. Reason: the four excluded UtilitiesCS.Test classes call the Windows shell icon API, which hangs process-wide on this workstation (measured on main by the operator on 2026-09-04, reproduced identically in a detached worktree); the runner hard-codes its filter and has no timeout, so an unmodified run stalls with no bounded failure. The exclusion is identical for baseline and final, so both figures describe the same test population, and every other runner step (discovery, derived settings, post-processing, 80 percent line and 75 percent branch assertions on the first-party document, first-party summary line, JaCoCo projection with reconciliation, trx summary, raw-document retention) executes verbatim. The four classes run unfiltered in the repository's mstest-coverage workflow on every pull request. The `/Blame` collector names any hanging test and writes a Sequence document; [P0-T12] and [P2-T6] gate on zero Sequence documents. Repository-wide figures are recorded and compared under Decision D10; the blocking coverage gates are per-file and per-changed-line. -- D4 (#863 disposition). Both fields are deleted rather than made private readonly. `Cache` has no reader in production or test code other than the not-null assertion, so a retained private readonly dictionary would be dead state that nothing publishes or consumes; `modules` has zero references. Repository guidance for dead code is removal, not exclusion. The `Cache_IsInitialized` test is deleted with the field and replaced by two structural tests that pin the property Expected Behavior 2 states (no public mutable static): `PublicStaticFields_AreAllInitOnly` and `PublicStaticFields_AreExactlyTheTwoOpCodeTables`. Both fail on the unfixed tree (the two public writable fields exist) and pass after the deletion, so the test class keeps a discriminating named assertion; the class grows from 14 to 15 test methods. +- D3 (coverage instrument). Baseline and final coverage both run the repository runner scripts/vscode/Invoke-MSTestWithCoverage.ps1 through its entry function after dot-sourcing (the script's entry guard skips the top-level call when dot-sourced), with one function replaced: `Get-DotnetCoverageArgumentList` is redefined to return the runner's own argument list plus four `FullyQualifiedName!~` exclusions and a /Blame hang collector.

The exclusion is identical for baseline and final, so both figures describe the same test population, and every other runner step (discovery, derived settings, post-processing, 80 percent line and 75 percent branch assertions on the first-party document, first-party summary line, JaCoCo projection with reconciliation, trx summary, raw-document retention) executes verbatim. The four classes run unfiltered in the repository's mstest-coverage workflow on every pull request. The /Blame collector names any hanging test and writes a Sequence document; [P0-T12] and [P2-T6] gate on zero Sequence documents. Repository-wide figures are recorded and compared under Decision D10; the blocking coverage gates are per-file and per-changed-line. +- D4 (#863 disposition). Both fields are deleted rather than made private readonly. `Cache` has no reader in production or test code other than the not-null assertion, so a retained private readonly dictionary would be dead state that nothing publishes or consumes; `modules` has zero references. Repository guidance for dead code is removal, not exclusion. The `Cache_IsInitialized` test is deleted with the field and replaced by two structural tests that pin the property Expected Behavior 2 states (no public mutable static): `PublicStaticFields_AreAllInitOnly` and `PublicStaticFields_AreExactlyTheTwoOpCodeTables`. Both fail on the unfixed tree (the two public writable fields exist) and pass after the deletion, so the test class keeps a discriminating named assertion; the class grows from 14 to 15 test methods. This removes two public members of UtilitiesCS; the in-repo consumer check is [P1-T11] and [P1-T13]. - D5 (#862 edit shape). Exactly one line changes per file: the token ` (487 lines)` is removed from line 11 of the bridge coordinator part and the token ` (481 lines)` from line 10 of the lifecycle coordinator part. No other wording changes, so the sentence still explains why the part exists. CSharpier does not reflow comments, so the edit is format-stable. The third bridge-coordinator partial part is not edited (Objective item 3). -- D6 (intermediate builds). [P1-T2], [P1-T5], [P1-T8] and [P1-T11] compile with the Build target because vstest never compiles and their only purpose is to produce the assembly the next scoped run reads; the scoped run is self-proving (a run reporting the new test's name proves it was compiled). Every diagnostic gate uses Rebuild and never passes the solution-wide Nullable property. The minimal console verbosity and detailed file-logger switches are logging-only additions; the `Task "Csc"` count from the detailed log is the non-vacuity observation for a Rebuild. +- D6 (intermediate builds). [P1-T2], [P1-T5], [P1-T8] and [P1-T11] compile with the CLAUDE.md type-check command (CMD-NULLABLE, Rebuild with TreatWarningsAsErrors), so every intermediate compile is a real diagnostic gate and no task uses the Build target. The Solution-wide Nullable property is never passed. The two red-state compiles ([P1-T2], [P1-T8]) are expected to succeed: the red state is a failing test, not a failing build, because neither new test method references a member that does not exist and neither test file carries a `#nullable enable` pragma (re-derived: both test files open with a plain `using` line). The minimal console verbosity and detailed file-logger switches are logging-only additions; the `Task "Csc"` count from the detailed log is the non-vacuity observation for a Rebuild. - D7 (committed evidence form). Coverage evidence committed under EVIDENCE is the runner's JaCoCo package projection file plus its one-line first-party summary; test-run evidence is the runner's trx-derived summary text or a summary transcribed from CMD-TRX-SUMMARY output. No .trx, .coverage, .cobertura.xml or msbuild log is copied into the feature folder. Raw documents stay under the coverage directory, which .gitignore line 144 excludes (line 145 re-includes only its .gitkeep). - D8 (commits and inherited residue). Commit tasks: [P0-T15] (Phase 0 evidence, exempt form), [P1-T16] (implementation, source-bearing), [P2-T12] (QA evidence, exempt form), [P2-T21] (terminal, exempt form). Staging is always by explicit pathspec; `git add -A` is never used. Every porcelain gate asserts SCOPE, never emptiness or a count: any path under the feature folder or under .claude/agent-memory/ is admitted by rule, because agents write memory during the run and the plan file's own check-off marks land after each commit. The [P0-T2] porcelain snapshot is recorded as `PreExistingWorktreePaths:` and admitted by rule wherever it is outside the Write Set. - D9 (fixed artifact names). Artifact filenames carry no timestamp segment so acceptance conditions can name them; the write time is the `Timestamp:` field. - D10 (repository-wide coverage comparison). The first-party summary line's lines-valid figure is compared between baseline and final. Branch A (the two lines-valid figures differ by at most 1 percent of the baseline figure): the first-party line percentage must not fall by more than 0.5 percentage points and the branch percentage must not fall by more than 0.5 percentage points. Branch B (they differ by more): the figures are recorded and not gated, and the artifact says so in one sentence. Exactly one branch is named. The hard, unbranched gates are per file: UiThread.cs uncovered-line count not above baseline and every changed executable line hit; ILGlobals.cs uncovered-line count not above baseline (its diff is deletions only). - D11 (green vstest console output). A passing vstest run prints `Test Run Successful.`, `Total tests:` and `Passed:` and prints neither a `Failed:` nor a `Skipped:` line. Counts are therefore read from the TRX through the repository's Get-TrxRunSummary reader (CMD-TRX-SUMMARY), which derives skipped as total minus executed and says so. - D12 (test placement and concurrency regime). The #889 test is added to the existing `UiThreadPredicateHardening_Tests` class, which already carries `[DoNotParallelize]` (line 22) because it installs process-global UiThread statics through the shared scope, which is documented as not internally synchronized. Adding a method there adds no new attribute and no new serialization. The #863 tests are added to `ILGlobals_Tests`, which carries no such attribute and gains none. No worker-count change, no retry, no sleep, no delay and no temporary file is introduced; [P2-T9] gates all of these. -- D13 (halting). Phase 0 halts, without editing anything, on: Outlook running after the user has been asked to close it; the branch check failing; a red baseline (csharpier check drift, either Rebuild exiting non-zero or a non-zero `Error(s)` summary, the coverage runner throwing, or any failed test in the baseline scoped runs); a pre-implementation checkpoint missing the keys [P0-T3] names. A red baseline makes AC6 unsatisfiable by this plan, so the executor reports BLOCKED with the artifact and stops. Bounded exception: the full coverage run is documented as load-flaky on this workstation (one known sporadic failure, `TryAddValuesAsync_UpdatesExistingValue`, issue #780); a first run that fails only on that named test may be repeated exactly once with no intervening file change, both runs recorded with their own timestamps and the repeat identified as a repeat, not as a loop restart. +- D13 (halting).

Every changed production line that remains executable is covered, and coverage does not regress. - [ ] AC7: Committed evidence follows the CLAUDE.md "Committed Test Evidence Format" section (projections and summaries only, no raw trx or raw coverage collector document), and no committed file contains an absolute host path, the developer account name, or the host name. diff --git a/docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/plan.2026-09-28T20-01.md b/docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/plan.2026-09-28T20-01.md index 3457bf81c..5126095d7 100644 --- a/docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/plan.2026-09-28T20-01.md +++ b/docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/plan.2026-09-28T20-01.md @@ -297,27 +297,27 @@ Delete line 113 (`public static Dictionary Cache = new Dictionary Date: Tue, 29 Sep 2026 09:25:42 -0400 Subject: [PATCH 08/15] docs(930): final QC evidence Co-Authored-By: Claude Opus 5.5 noreply@anthropic.com Claude-Session: https://claude.ai/code/session_01KNZiXntshsLY8vqqCHUvHm --- .../evidence/baseline/outlook-state.md | 12 + .../evidence/qa-gates/concurrency-regime.md | 14 ++ .../evidence/qa-gates/coverage-comparison.md | 19 ++ .../evidence/qa-gates/evidence-hygiene.md | 18 ++ .../qa-gates/final-01-csharpier-format.md | 12 + .../qa-gates/final-02-csharpier-check.md | 10 + .../evidence/qa-gates/final-03-file-size.md | 14 ++ .../evidence/qa-gates/final-04-analyzers.md | 15 ++ .../evidence/qa-gates/final-05-nullable.md | 15 ++ .../qa-gates/final-06-mstest-coverage.md | 229 ++++++++++++++++++ .../qa-gates/final-coverage.jacoco.xml | 38 +++ .../evidence/qa-gates/final-test-summary.txt | 5 + .../evidence/qa-gates/footprint.md | 36 +++ .../evidence/qa-gates/toolchain-final-pass.md | 21 ++ .../plan.2026-09-28T20-01.md | 24 +- 15 files changed, 470 insertions(+), 12 deletions(-) create mode 100644 docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/concurrency-regime.md create mode 100644 docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/coverage-comparison.md create mode 100644 docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/evidence-hygiene.md create mode 100644 docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/final-01-csharpier-format.md create mode 100644 docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/final-02-csharpier-check.md create mode 100644 docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/final-03-file-size.md create mode 100644 docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/final-04-analyzers.md create mode 100644 docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/final-05-nullable.md create mode 100644 docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/final-06-mstest-coverage.md create mode 100644 docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/final-coverage.jacoco.xml create mode 100644 docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/final-test-summary.txt create mode 100644 docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/footprint.md create mode 100644 docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/toolchain-final-pass.md diff --git a/docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/baseline/outlook-state.md b/docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/baseline/outlook-state.md index e34f519b8..e40edbc7b 100644 --- a/docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/baseline/outlook-state.md +++ b/docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/baseline/outlook-state.md @@ -5,3 +5,15 @@ Command: pwsh -NoProfile -Command 'if (Get-Process -Name OUTLOOK -ErrorAction Si EXIT_CODE: 0 Output Summary: - OUTLOOK_STATE=CLOSED + +## Re-runs (appended) + +Each re-run used the same command;

This count is advisory; [P2-T3] after the format pass is authoritative. Fallback if any value exceeds 500 after formatting: for a test file, shorten the XML doc comments of the new tests to one summary line each (never delete an assertion); for UiThread.cs (308 lines, no risk), no fallback is needed. -- [ ] [P1-T16] Commit the implementation: `git add -- UtilitiesCS/Threading/UiThread.cs "UtilitiesCS/NewtonsoftHelpers/SDIL Reader/ILGlobals.cs" QuickFiler/Viewers/BreadcrumbBridgeCoordinator.Search.cs QuickFiler/Viewers/BreadcrumbItemViewerLifecycleCoordinator.Search.cs UtilitiesCS.Test/Threading/UiThreadApartmentMeasurement_Tests.cs UtilitiesCS.Test/NewtonsoftHelpers/SDILReader/ILGlobals_Tests.cs docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930` then `git commit -m "fix(930): UiThread dispatcher-exit null guard, ILGlobals dead statics, stale doc-comment line counts Co-Authored-By: Claude Opus 5.5 noreply@anthropic.com"`.

No artifact is written by this task; the SHA is reported in the executor's return. ### Phase 2 — Final QC loop, coverage comparison, evidence hygiene, reduced-audit handoff and AC check-off Loop rule (unconditional, no SKIPPED path): [P2-T1] through [P2-T6] are one toolchain pass in CLAUDE.md order. If any of them fails its acceptance, or [P2-T1] rewrote any file, restart at [P2-T1]; every restarted task overwrites its artifact with a new `Timestamp:` and increments `Iteration:`. [P2-T7] and [P2-T8] evaluate the latest iteration only. If an iteration of [P2-T1] rewrote a Write Set source file, commit that rewrite before restarting with `git add -- ` and `git commit -m "style(930): csharpier Co-Authored-By: Claude Opus 5.5 noreply@anthropic.com"` (a source-bearing commit under the same gate as [P1-T16]), so the loop's later anchored diffs describe committed state. If [P2-T1] reports a rewritten path outside the Write Set (`FORMAT_NEW_PATHS` non-empty), stop and report FORMAT-SCOPE-BREACH naming the paths; [P0-T9] established that no drift existed at baseline, so such a rewrite is not this item's repair. -- [ ] [P2-T1] Toolchain step 1, write-mode format: CMD-FORMAT (BASE substituted).

Acceptance on the final iteration: `FORMAT_EXIT=0`, `FORMAT_CHANGED_OWNED_PATCH=False`, `FORMAT_NEW_PATHS=` empty, and no porcelain line names a path under UtilitiesCS, UtilitiesCS.Test or QuickFiler. -- [ ] [P2-T2] Toolchain step 1 verification, read-only: CMD-FORMAT-CHECK.

Artifact EVIDENCE/qa-gates/final-03-file-size.md. Acceptance: all six `LINES` values are at most 500 (expected 308, 225, 102, 45, at most 210, at most 320); a value above 500 applies the [P1-T15] fallback and restarts the loop at [P2-T1]. -- [ ] [P2-T4] Toolchain step 2, analyzers: CMD-ANALYZE with STAGE = final, then CMD-MSBUILD-SUMMARY with LOG = 930-final-analyzers.detailed.log. Artifact EVIDENCE/qa-gates/final-04-analyzers.md. Acceptance: `MSBUILD_EXIT=0`, `ERROR_SUMMARY_LINE` is `0 Error(s)`, `CSC_TASK_LINES` at least 1, and the `WARNING_SUMMARY_LINE` count is at most the `BASELINE-ANALYZER-WARNINGS:` count from [P0-T10] (a higher count is a new analyzer diagnostic introduced by this diff; fix and restart). -- [ ] [P2-T5] Toolchain step 3, nullable: CMD-NULLABLE with STAGE = final, then CMD-MSBUILD-SUMMARY with LOG = 930-final-nullable.detailed.log.

Acceptance: `MSBUILD_EXIT=0`, `ERROR_SUMMARY_LINE` is `0 Error(s)`, `CS86_ERROR_LINES=0`, `CSC_TASK_LINES` at least 1. -- [ ] [P2-T6] Toolchain step 4, tests with coverage: CMD-COVERAGE with STAGE = final (identical exclusion set to [P0-T12], Decision D3), then CMD-COVERAGE-PARSE with STAGE = final and CMD-RETURN-LINE. Copy coverage/930-final.cobertura.jacoco.xml to EVIDENCE/qa-gates/final-coverage.jacoco.xml and coverage/test-results/930-final/930-final.summary.txt to EVIDENCE/qa-gates/final-test-summary.txt. Artifact EVIDENCE/qa-gates/final-06-mstest-coverage.md with the same fields and `Output Summary:` content shape as [P0-T12] (the `First-party coverage:` line verbatim with its numeric post-change line and branch percentages, the document figures, the summary text, the exclusion sentence, `SEQUENCE_FILES=`, both `FILE` blocks with every `LINE` row, `FINAL-RETURN-LINE:`, `FINAL-RETURN-HITS:`, `FINAL-RETURN-COND:`). Acceptance: `RUNNER_RESULT=COMPLETED` (which implies the runner's own 80 percent line and 75 percent branch first-party assertions passed and the projection reconciled), `COBERTURA_EXISTS=True`, `PROJECTION_EXISTS=True`, `SUMMARY_EXISTS=True`, `SEQUENCE_FILES=0`, `Test run outcome: Completed` with failed 0 (Decision D13 repeat rule applies to the one named flaky test; a second failure of any test restarts the loop after a fix, never with a retry switch), the summary's `Total` equals `BASELINE-SUITE-TOTAL:` from [P0-T12] plus 2 (one #889 test plus one net #863 test: two added, one deleted), and CMD-TRX-NAMES with STAGE = final (its output appended to this artifact) prints `COUNT=1 OUTCOME=Passed` for the three new names and for all twelve pre-existing `IsCompleted` names and `COUNT=0 OUTCOME=absent` for `Cache_IsInitialized` (confirming [P1-T6] and [P1-T12], which are the measured runs; disagreement is recorded as a failure of this task), `RETURN_LINE_MATCHES=1`, `GUARD_COUNT=2`. On `RUNNER_RESULT=THREW`, run CMD-TRX-SUMMARY with STAGE = final (vstest writes the trx before the runner throws); if its `Failed tests:` line names exactly `TryAddValuesAsync_UpdatesExistingValue` and `SEQUENCE_FILES=0`, apply the Decision D13 single repeat; any other `THREW` result restarts the loop after a fix. Both `FILE` lines print `CLASS_NODES` at least 1 and `LINES_VALID` at least 1 (the per-file predicate matched the processed document's backslash-separated file name). -- [ ] [P2-T7] Coverage comparison, baseline versus post-change versus changed lines.

Acceptance (all unbranched except the first-party pair): `UITHREAD-UNCOVERED` final at most baseline; `ILGLOBALS-UNCOVERED` final at most baseline; final return-line `HITS` at least 1; guard-line `HITS` at least 1 or no line element; if `BASELINE-RETURN-COND` was a condition-coverage value then `FINAL-RETURN-COND` has covered equal to total (the new test covers the null outcome, the owning-thread test the true outcome, the different-dispatcher test the false reference outcome), otherwise the field is recorded with the sentence that condition coverage was not reported for that line; under Branch A the first-party line and branch percentages each fall by at most 0.5 points, under Branch B they are recorded and the artifact says the denominators are not comparable; exactly one branch is named.

No Blocking finding. One Non-blocking finding concerns committed evidence text rather than code (an absolute Program Files path on two lines, contradicting AC7's literal text).

The remaining public static fields are `readonly` and published once from the static constructor (unchanged since #824). +- `using System.Reflection;` is still required (`FieldInfo`); `using System.Collections.Generic;` is now unused (informational finding above). + +### QuickFiler/Viewers/*.Search.cs + +- Both comments now read "Held on a second partial-class part so `...` stays clear of the repository's 500-line ceiling" with the numeral removed and the explanation intact. CSharpier did not reflow the comment (the write-mode format pass left the patch unchanged). The bridge coordinator's third partial part, which carries a historical sentence with a past line count, was not edited; the anchored numstat over `QuickFiler/Viewers` lists exactly the two Search parts. + +### UtilitiesCS.Test/Threading/UiThreadApartmentMeasurement_Tests.cs (new test, lines 99 to 138) + +- Arrangement satisfies the five conditions AC1 enumerates: `SetDispatcher(null)` (no captured dispatcher); `SetUiThreadId(Thread.CurrentThread.ManagedThreadId)` on the executing MTA thread; awaiter context `new DispatcherSynchronizationContext(foreignHost.Dispatcher)` (a dispatcher context that is not the captured UI context); ambient context `new SynchronizationContext()` (non-null, differs from the awaiter context); executing thread created as MTA by `ApartmentThreadRunner`, which owns no WPF dispatcher. +- The dispatcher-taking `DispatcherSynchronizationContext` constructor is used deliberately so no dispatcher is created on the test worker thread (the XML doc explains this; the parameterless constructor would create one and never shut it down). +- Assertions: `thrown.Should().BeNull()` guards against a swallowed exception being read as `false`; `observed.Should().BeFalse()` is the behavioral assertion. `observed` is initialized to `true` so an unexecuted delegate cannot pass. Good defensive shape, consistent with the two sibling tests. +- Fail-before evidence: the test failed with "Expected observed to be False, but found True" against unmodified source, which is precisely the defect. + +### UtilitiesCS.Test/NewtonsoftHelpers/SDILReader/ILGlobals_Tests.cs (new tests, lines 264 to 313) + +- `PublicStaticFields_AreAllInitOnly`: `NotBeEmpty` first (so an empty reflection result cannot pass vacuously), then `OnlyContain(field => field.IsInitOnly, ...)`. Fail-before output named both offending fields by type and name. +- `PublicStaticFields_AreExactlyTheTwoOpCodeTables`: `BeEquivalentTo` on the name array is order-insensitive, which is correct for reflection output. Uses `nameof(...)` so a rename fails at compile time rather than at run time. +- "Arrange & Act" combined into one comment is acceptable for a single reflection call. + +### Concurrency and determinism + +- `ADDED_DoNotParallelize=0`, `ADDED_Thread.Sleep=0`, `ADDED_Task.Delay=0`, `ADDED_Workers=0`, `ADDED_Retry=0`, `ADDED_GetTempFileName=0`, `ADDED_GetTempPath=0` over 93 added diff lines; runsettings hash unchanged (Workers 0, ClassLevel). The new #889 test relies on the pre-existing class-level `[DoNotParallelize]`, which is appropriate because it mutates process-global `UiThread` statics. + +### Evidence integrity notes + +- The executor's disclosure that several Phase 0 `Timestamp:` values were estimates later replaced by file write times affects no measured figure and no acceptance criterion; the sequence is monotone and consistent with the later phases. Recorded in the policy audit as I-1. +- Both committed JaCoCo projections re-sum exactly to the runner's first-party summary lines; the per-file Cobertura parse figures reconcile with the package-level delta except for six lines elsewhere in UtilitiesCS that flipped missed-to-covered between runs (run-to-run variance, 0.009 points). diff --git a/docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/feature-audit.2026-09-29T00-45.md b/docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/feature-audit.2026-09-29T00-45.md new file mode 100644 index 000000000..7de24e131 --- /dev/null +++ b/docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/feature-audit.2026-09-29T00-45.md @@ -0,0 +1,67 @@ +# Feature Audit: csharp-latent-hazards-uithread-ilglobals-comments (Issue #930) + +- Timestamp (caller-supplied artifact stamp): 2026-09-29T00-45 +- Branch: `bug/csharp-latent-hazards-uithread-ilglobals-comments-930` +- Work mode: `minor-audit` (issue.md marker `- Work Mode: minor-audit`) +- AC source: `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/issue.md`, section `## Acceptance Criteria` (AC1 to AC7).

Non-blocking: 1. Informational: 9. + +The branch delivers three independent latent-defect fixes in C#: a null guard on the dispatcher exit of `UiThread.SynchronizationContextAwaiter.IsCompleted` (#889), deletion of two public mutable static fields from `SDILReader.ILGlobals` (#863), and removal of stale numeric line counts from two XML doc comments (#862). Each fix is preceded by a regression test recorded failing against unmodified source (#889, #863) or by a token census (#862). The full C# toolchain passed in one clean iteration (CSharpier check over 1623 files, analyzer Rebuild 0 errors and 0 warnings, TreatWarningsAsErrors Rebuild 0 errors, 7322 of 7322 tests passed). First-party C# coverage moved from 85.31% lines / 79.71% branches to 85.32% lines / 79.73% branches; the single changed executable production line is covered and its condition coverage reads 4/4. The one Non-blocking finding is that two committed evidence files carry the absolute install path of `vstest.console.exe` under Program Files, which contradicts the literal text of AC7 ("no committed file contains an absolute host path") and the plan's own placeholder instruction, while disclosing neither the account name nor the host name. AC7 was unchecked in issue.md; the remedy is a placeholder substitution on two lines. + +Coverage floors applied: CLAUDE.md governs C# (80% line / 75% branch repo-wide, 90% target for new code, no regression on changed lines); `.claude/rules/general-unit-test.md` and `quality-tiers.md` state 85% line / 75% branch. Both floor sets are satisfied by the post-change first-party figures, so the documented conflict between the two floor statements does not affect this verdict. + +## 1. General Unit Test Policy Compliance + +### 1.1 Core Principles + +| Principle | Verdict | Evidence | +|---|---|---| +| Independence | PASS | The #889 test is added to `UiThreadPredicateHardening_Tests`, which already carries `[DoNotParallelize]` because it installs process-global `UiThread` statics through `UiThreadStateScope`; the scope is entered and disposed per test.

The percentage decrease is the arithmetic effect of deleting two covered field-initializer lines; the diff for this file is deletions only, so there is no changed-line regression. +- `QuickFiler/Viewers/BreadcrumbBridgeCoordinator.Search.cs` and `BreadcrumbItemViewerLifecycleCoordinator.Search.cs`: comment-only edits; no executable line changed. +- Test files (`UtilitiesCS.Test/...`) are excluded from the coverage denominator by the runner's first-party filter. + +Reviewer cross-check of the committed projections: the nine package counters in evidence/baseline/baseline-coverage.jacoco.xml sum to 56079 covered of 65737 lines and 13593 of 17052 branches; evidence/qa-gates/final-coverage.jacoco.xml sums to 56084 of 65736 and 13597 of 17054. Both sums equal the runner's first-party summary lines verbatim. The only package whose counters changed is UtilitiesCS (missed 4614 to 4608, covered 38810 to 38815). The changed files account for covered minus 1 and missed 0, so six lines elsewhere in UtilitiesCS flipped from missed to covered between the two runs (0.009 percentage points); this is within the known run-to-run variance of the full suite and is not attributable to the diff. + +Method note on the four excluded test classes (plan Decision D3): both local coverage runs excluded `ShellUtilities_Tests`, `ShellUtilitiesStatic_Tests`, `SysImageListHelperTests` and `OSBrowser_Tests` via an identical `FullyQualifiedName!~` filter because they call the Windows shell icon API, which hangs on this workstation. The exclusion is identical on both sides of the comparison, so the delta is sound; the absolute first-party figure is an under-approximation of the CI figure, and the repository `mstest-coverage` workflow runs the four classes unfiltered on every pull request. The exclusion is a test-selection filter on the local runs, not a coverage `exclude` entry on a production path, so the Coverage Exclusion Policy blocking rule is not engaged. + +### Coverage Evidence Checklist + +- C# baseline coverage artifact: `evidence/baseline/baseline-coverage.jacoco.xml` (package-level JaCoCo projection) plus `evidence/baseline/baseline-04-mstest-coverage.md` (first-party summary line and per-file Cobertura parse) +- C# post-change coverage artifact: `evidence/qa-gates/final-coverage.jacoco.xml` plus `evidence/qa-gates/final-06-mstest-coverage.md` +- TypeScript baseline coverage artifact: `N/A - zero TypeScript files changed on this branch` +- TypeScript post-change coverage artifact: `N/A - zero TypeScript files changed on this branch` +- PowerShell baseline coverage artifact: `N/A - zero PowerShell files changed on this branch` +- PowerShell post-change coverage artifact: `N/A - zero PowerShell files changed on this branch` +- Python baseline coverage artifact: `N/A - zero Python files changed on this branch` +- Python post-change coverage artifact: `N/A - zero Python files changed on this branch` +- Per-language comparison summary: section 1.2.1 of this document + +Note on the canonical artifact path: `artifacts/csharp/coverage.xml` does not exist in the review worktree (no `artifacts/` directory exists there).

The committed package-level JaCoCo projection plus the transcribed per-file parse are treated as the coverage artifact for this review, consistent with prior reviews of this repository. A `artifacts/csharp/coverage.xml` present in the session checkout is a stale Cobertura document from a different branch (lines-valid 64740, timestamp 2026-09-05) and was not used as evidence. + +### 1.2.1 Per-Language Coverage Comparison + +- C#: Baseline: 85.31% lines (56079/65737) / 79.71% branches (13593/17052) -> Post-change: 85.32% lines (56084/65736) / 79.73% branches (13597/17054).

The change is called out in plan Decision D4 and in reduced-audit-handoff.md; the policy's "call it out clearly in the change description" obligation is discharged only when the PR body names both removed members. The deleted `Cache_IsInitialized` test asserted only the existence of the deleted member and is replaced by two structural tests, so the existing-tests-as-spec rule is satisfied. | +| After making changes (toolchain loop) | PASS | evidence/qa-gates/toolchain-final-pass.md: `LOOP: CLEAN PASS`, one iteration, no source-rewrite commits. | +| Architecture boundaries | PASS | No new reference to VSTO, Outlook Interop, COM visibility or Ribbon callbacks. `UiThread.cs` already references `System.Windows.Threading` (WPF), unchanged. | + +## 3.

The only tool-derived committed evidence is two package-level JaCoCo projections and two trx-derived summaries; `RAW_TOOL_DOCS=0` over the feature folder; both projections parse with 9 packages. +- Evidence hygiene: PARTIAL. Account name, host name, worktree root and `:\Users\` prefix all read 0 hits with positive controls at least 1 (evidence/qa-gates/evidence-hygiene.md). However, two committed lines carry the absolute install path `C:\Program Files\Microsoft Visual Studio\18\Community\Common7\IDE\Extensions\TestPlatform\vstest.console.exe` (evidence/baseline/baseline-04-mstest-coverage.md line 11; evidence/qa-gates/final-06-mstest-coverage.md line 12). The sanitize gate's four patterns do not match a Program Files path, so the gate passed while the AC7 clause "no committed file contains an absolute host path" is not met literally. See section 8, finding NB-1. + +## 8. Gaps and Exceptions + +### NB-1 (Non-blocking): absolute host path in two committed evidence lines + +- Files: `evidence/baseline/baseline-04-mstest-coverage.md` line 11 and `evidence/qa-gates/final-06-mstest-coverage.md` line 12, both reading `Runner output: Using vstest.console: C:\Program Files\Microsoft Visual Studio\18\Community\Common7\IDE\Extensions\TestPlatform\vstest.console.exe; ...`. +- Rule: AC7 in issue.md ("no committed file contains an absolute host path, the developer account name, or the host name") and the plan's executor note ("Use the placeholders REPO-ROOT, USER-PROFILE, USER and HOST when a value outside the repository must be described"). +- Impact: no identity disclosure (no account or host name; the path is a standard Visual Studio install location), so the Committed Test Evidence Format policy's purpose is met; the literal AC clause is not. AC7 has been unchecked in issue.md. +- Remedy: replace the path prefix on both lines with a placeholder (for example `PROGRAM-FILES\Microsoft Visual Studio\18\Community\...` or the token `VSTEST-CONSOLE`), commit in the exempt docs-only form, and re-check AC7. No code change is involved. + +### I-1 (Informational): Phase 0 `Timestamp:` values were estimates, later replaced by file write times + +- Disclosed in reduced-audit-handoff.md ("several Phase 0 artifact `Timestamp:` values were first written as estimates and were corrected in the [P1-T16] commit to the observed file write times"). The plan's convention is a CMD-TS observation at run time, so the corrected values are a post-hoc substitute rather than the prescribed observation. The git history retains both states (Phase 0 commit `df86ec9e`, correction in `699ad109`). +- Effect on evidence integrity: none on any measured figure. No acceptance criterion depends on a Timestamp value; every AC rests on exit codes, counts, test names and coverage figures that were not edited. The current Phase 0 sequence (08-51 through 09-08) is monotone and consistent with the timestamps of the later phases (09-11 onward) and with the internal mention of a first analyzer invocation at 08-54 inside baseline-02-analyzers.md. +- Residual weakness: the disclosure does not enumerate which artifacts were corrected, and a file-write time can post-date the command it labels. Recommend enumerating the corrected artifact names in the handoff if the folder is revised for NB-1. + +### I-2 (Informational, pre-existing, out of footprint): analyzer HintPath skew on origin/main + +- `UtilitiesCS.csproj` and `VBFunctions.csproj` reference `Meziantou.Analyzer.3.0.235` in their `` items while packages.config and the `.props` import name 3.0.290; `SVGControl.Test.csproj` references `MSTest.Analyzers.4.4.0` while packages.config names 4.4.1. On a fresh worktree the analyzer Rebuild fails with 4 CS0006 errors until the two older versions are installed into the gitignored packages directory, which the executor did (baseline-02-analyzers.md). No tracked file changed (`git status --porcelain` over csproj/config/props/targets/packages printed nothing). +- Classification: pre-existing environment defect on origin/main, outside this diff's footprint; consistent with the known pattern of a NuGet version bump leaving stale `` paths. Recommend a follow-up issue to align the `` versions with packages.config; a CI analyzer run on a cold checkout would also fail on this unless it restores the older versions. + +### I-3 (Informational): breaking public API change obligation + +- `ILGlobals.Cache` and `ILGlobals.modules` removed from UtilitiesCS. In-repo consumers: none (three independent checks listed in section 2). The general policy requires the removal to be called out in the change description; the PR body must name both members. `quality-tiers.yml` does not exist at the repository root of this branch, so the tier-dependent "major bump required" gate for contract-breaking changes is not operable here; the call-out obligation is the applicable control. + +### I-4 (Informational): unused `using System.Collections.Generic;` left in ILGlobals.cs + +- After the `Dictionary Cache` deletion, a Grep over the file for `Dictionary|IList|List<|IEnumerable|ICollection|HashSet|KeyValuePair|Queue<|Stack<|IReadOnly|Comparer<|EqualityComparer` returns zero matches, so the directive at line 3 appears unused. The analyzer Rebuild reported 0 warnings, so no enabled rule flags it. Removal is a one-line cleanup for a later touch of this file; leaving it is consistent with the minimal-fix rule. + +### I-5 (Informational): six UtilitiesCS lines outside the changed files flipped missed-to-covered between runs + +- Package delta (UtilitiesCS missed minus 6, covered plus 5) exceeds what the changed files explain (covered minus 1, missed 0) by six covered lines elsewhere in the assembly; 0.009 percentage points, within the known full-suite run-to-run variance. Not attributable to the diff; recorded so the package-level delta is not read as an effect of the change. + +### I-6 (Informational): four shell-icon test classes excluded from both local coverage runs (plan Decision D3) + +- Identical exclusion on both sides; CI runs the classes unfiltered on every pull request. The executor also reports that `scripts/vscode/Invoke-MSTestWithCoverage.ps1` hard-codes its test-case filter and exposes no filter or hang-timeout extension point, which forced a function override to apply the exclusion; candidate follow-up, no obligation created by this branch. + +### I-7 (Informational): PR-context artifacts absent for this branch + +- No `artifacts/` directory exists in the review worktree, and the caller prohibited Bash; scope was derived from the caller-supplied diff and verified against footprint.md and the files on disk. The session checkout's `artifacts/pr_context.summary.txt` belongs to a different branch (`documentationandmemories`, head `1c80f6e0`) and lists only `.md` files. + +### I-8 (Informational): ILGlobals.cs file-level percentage decreased while its uncovered count did not + +- 95.00% to 94.74% because two covered field-initializer lines were deleted; not a changed-line regression (the file's diff is deletions only). Recorded so the per-file figure is not misread. + +### I-9 (Informational, pre-existing): test file hosts two classes + +- `UtilitiesCS.Test/Threading/UiThreadApartmentMeasurement_Tests.cs` contains both `UiThreadPredicateHardening_Tests` (where the #889 test was added, per the plan) and `UiThreadApartmentMeasurement_Tests`. The file name matches only the second class. Pre-existing arrangement from #816; not changed by this branch. + +## 9. Summary of Changes + +- `UtilitiesCS/Threading/UiThread.cs` (+2/-0): one comment line and the operand `&& _dispatcher is not null` inserted into the dispatcher exit of `SynchronizationContextAwaiter.IsCompleted`, matching the guard the captured-context exit already carries. +- `UtilitiesCS/NewtonsoftHelpers/SDIL Reader/ILGlobals.cs` (+0/-3): `public static Dictionary Cache` and `public static Module[]? modules` deleted. +- `QuickFiler/Viewers/BreadcrumbBridgeCoordinator.Search.cs` (+1/-1) and `BreadcrumbItemViewerLifecycleCoordinator.Search.cs` (+1/-1): the tokens ` (487 lines)` and ` (481 lines)` removed from XML doc comments. +- `UtilitiesCS.Test/Threading/UiThreadApartmentMeasurement_Tests.cs` (+42): one regression test and `using System.Windows.Threading;`. +- `UtilitiesCS.Test/NewtonsoftHelpers/SDILReader/ILGlobals_Tests.cs` (+51/-6 net +45): `Cache_IsInitialized` replaced by `PublicStaticFields_AreAllInitOnly` and `PublicStaticFields_AreExactlyTheTwoOpCodeTables`; `using System.Linq;` added. +- Feature folder: issue.md (AC check-offs), plan check-offs, 44 evidence files.

Scope source for this cycle: remediation-inputs.2026-09-29T09-50.md in this folder. No spec.md, user-story.md or research file exists or is required; execution, validation and audit fail closed if spec.md or user-story.md appears in this folder. +- **Branch:** bug/csharp-latent-hazards-uithread-ilglobals-comments-930. The diff anchor is the execution-time self-anchor R1-BASE recorded by [P0-T2] (Decision R1-D1); no commit literal is pinned in this plan. +- **Provenance:** every file, line and count below was re-derived on 2026-09-29 against the tree in the assigned worktree by a Grep of the feature folder for a drive letter, a colon, a path separator and a following character (word-boundary anchored). The Grep returned exactly seven hit lines in five files, listed in [P0-T3], and one non-hit control line in issue.md (a URL scheme). + +**Fail-closed evidence rule:** every gate below writes an artifact; if any required artifact is missing or carries incomplete fields, the audit verdict is BLOCKED or INCOMPLETE, never PASS. + +**Evidence accounting rule:** every evidence-producing task names its artifact path. Do not mark evidence-backed work complete without the artifact. + +> Formatting rule for this document (do not "fix" it): a downstream extractor harvests backticked, whitespace-free tokens from this file to compute the item's blast radius. Repository paths therefore appear in backticks only in the Write Set section. Every other repository path here is plain prose, the plain token FEATURE or EVIDENCE followed by a relative path, or sits inside a multi-word command span. + +## Executor notes (record now, act at execution time) + +- Run the execution child NON-ISOLATED with Bash permission for git and pwsh. Under Agent worktree isolation the Bash tool refuses pwsh, and every measurement command below is a pwsh invocation. +- Work only in the assigned worktree. The Bash tool's working directory is the session checkout, not the worktree, and `cd` is prohibited. WORKTREE-ROOT in this plan stands for the absolute worktree root supplied on the orchestrator's WORKTREE line, written with forward slashes. Every pwsh span in the Command Reference begins with `Set-Location -LiteralPath WORKTREE-ROOT;` inside the outer single quotes, and every git command outside a pwsh span is written `git -C WORKTREE-ROOT ...` (the pre-implementation gate admits this selector form when the value is a literal drive-rooted path with no dot segment, wildcard or extra colon). The executor substitutes the literal root only in the command it runs. Every artifact's `Command:` field records the command with WORKTREE-ROOT left unsubstituted, because a substituted root is a drive-rooted path and would fail [P2-T1] and [P2-T2]. R1-BASE stays substituted. For the Read, Edit, Write, Grep and Glob tools, every FEATURE, EVIDENCE, policy-file and plan path in this plan is a path relative to WORKTREE-ROOT; the executor passes the tool the substituted absolute path WORKTREE-ROOT followed by a forward slash and the relative path. A tool call rooted at the session checkout is a defect even though the same relative path exists there. The substituted root appears in tool arguments only and never in an artifact, so every path an artifact records (including the `Files Read:` list of [P0-T1]) is the relative form. [P0-T2] proves the resulting condition with `CWD_IS_TOPLEVEL=True` and `TOPLEVEL_LEAF`. +- Bash discipline: only single commands whose first token is git, gh, pwsh, poetry, dotnet or msbuild, no chaining. Read and search with the Read, Grep and Glob tools; change text with the Edit tool. Never `git add -A`. +- Do not rebase, merge, reset or otherwise move the branch. The only history operations are the two commits named in [P2-T5] and [P2-T6] and the push in [P2-T6]. +- Placeholder rule: no committed file and no artifact written by this plan may contain a real drive-rooted path, the account name, the host name or the worktree root. Use the placeholders REPO-ROOT, USER-PROFILE, USER, HOST and VS-INSTALL-ROOT. The Visual Studio install path is read from the tree with the Read tool only to build the Edit tool's search text; it is never transcribed into an artifact, a command, or this plan. +- pwsh quoting rule: every `pwsh -NoProfile -Command '...'` span uses OUTER SINGLE quotes and INNER DOUBLE quotes. A backslash that must reach a regular expression is built from `[char]92`, a colon that would form a drive prefix is built from `[char]58`, and a doubled backslash is never written in a span. A literal single quote is never written. Copy spans verbatim. +- Every literal counted by the Grep tool is a fixed string. The Grep tool takes a regular expression, so escape each of the characters [ ] ( ) . in the literal with one backslash before searching, for example `- \[x\] AC`. Affected tasks: [P0-T6], [P2-T4]. +- Commit attribution: the commit subject in [P2-T5] ends with the angle-bracket-free trailer text the task quotes, and the second `-m` argument carries the Claude-Session line. The pre-implementation gate hook admits a no-checkpoint commit only in the exempt form used by [P2-T5] and [P2-T6]: `git -C WORKTREE-ROOT commit -m "SUBJECT" -m "SESSION-LINE" -- FEATURE-PATH`, one segment, with the root substituted by the literal absolute root, and with no dollar sign, backtick or angle bracket on the executed line. The bare `git commit` form is never used, because the Bash tool's working directory is the session checkout. +- No C# toolchain step (format, analyzers, nullable, MSTest coverage) is planned because no C# file changes in this cycle. That statement is not assumed: [P1-T6] and [P2-T3] prove it with anchored diffs and a porcelain listing, and any code or configuration path in the cycle diff halts the run BLOCKED. + +## Objective and decided remedy + +Finding NB-1 (the only in-scope finding): two committed evidence lines transcribe the coverage runner's `Using vstest.console:` output including the absolute Visual Studio install path, and the three audit artifacts of 2026-09-29T00-45 quote the same path when describing the finding. AC7 requires that no committed file contains an absolute host path. The escape occurred because the executed plan's sanitize gate searched for four named identity patterns (account, host, worktree root, a drive-rooted Users directory) and none matches a path under Program Files, so the gate read zero while the path was present. + +Invariant to restore: no file under this feature folder contains any drive-rooted absolute path (a drive letter, a colon, a path separator, then a path segment). The gate is drive-rooted in general, not a list of known directories, and carries a positive control. + +Remedy: replace the Visual Studio install directory prefix with the placeholder VS-INSTALL-ROOT in the five hit files (two evidence files, three audit artifacts), changing only that text. Then re-scan with the general pattern, re-run the existing four-pattern sanitize counts, check off AC7 on verified evidence, commit in the exempt form and push. The out-of-scope Informational items in remediation-inputs.2026-09-29T09-50.md are not touched. + +Root-cause demonstration built into this plan: [P0-T3] (general scan) reads 7 hits while [P0-T5] (the old four patterns) reads 0 on the same tree, both with controls, so the baseline proves the old gate could not see the defect and the new gate can. + +## Write Set + +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/issue.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/remediation-plan.2026-09-29T09-50.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/code-review.2026-09-29T00-45.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/policy-audit.2026-09-29T00-45.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/feature-audit.2026-09-29T00-45.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/baseline/baseline-04-mstest-coverage.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/final-06-mstest-coverage.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/remediation-baseline/r1-phase0-instructions-read.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/remediation-baseline/r1-tree-anchor.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/remediation-baseline/r1-drive-scan-baseline.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/remediation-baseline/r1-file-state-baseline.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/remediation-baseline/r1-sanitize-baseline.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/remediation-baseline/r1-ac-baseline.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/r1-subst-1.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/r1-subst-2.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/r1-subst-3.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/r1-subst-4.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/r1-subst-5.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/r1-footprint.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/r1-drive-scan-final.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/r1-sanitize-final.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/r1-toolchain-exemption.md` +- `docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/evidence/qa-gates/r1-ac-status.md` + +The Write Set is 23 files: issue.md, this plan, the three audit artifacts, the two evidence files carrying the path, and 16 new evidence files (6 remediation-baseline, 10 qa-gates) written under fixed names.

No commit literal is pinned here because the branch head moves. +- R1-D2 (gate pattern is general, not a list). The invariant is enforced by CMD-DRIVE-SCAN, a word-boundary-anchored drive letter, colon, separator and following character over every file in FEATURE. It carries three synthetic controls (backslash form must match, slash form must match, a URL scheme must not match) and two real controls (the raw final coverage log under the gitignored coverage directory must match at least once; issue.md carries a URL line and must not match). A pattern that matched a URL scheme, or that matched nothing, fails a control. +- R1-D3 (edit is provably placeholder-only). CMD-FILE-STATE hashes each file's text after an in-memory application of exactly the intended edit, recorded before any edit in [P0-T4]. After each edit, the file's on-disk text hash must equal that recorded value, so a change to any other character, figure, exit code or field fails the gate. For the three audit artifacts and two evidence files the in-memory edit replaces the drive letter through the edition directory (the text ending before the separator preceding Common7) with VS-INSTALL-ROOT; for issue.md it flips the AC7 marker only. +- R1-D4 (audit artifacts are edited only by substitution). The three audit artifacts of 2026-09-29T00-45 quote the path while describing the finding, so they fall under AC7. They may be edited only by the placeholder substitution; the substitution leaves their verdicts, finding text and line counts unchanged, which R1-D3 enforces. +- R1-D5 (no C# toolchain). No C# source, test, project, props, targets, solution, runsettings or configuration file changes. [P1-T6] and [P2-T3] prove it. A toolchain run over an unchanged C# tree would measure nothing this cycle changed. If either gate lists a code or configuration path, the run halts BLOCKED and a toolchain loop is required by a revised plan. +- R1-D6 (commits and residue). Staging is always by explicit pathspec over FEATURE; `git add -A` is never used. Porcelain gates assert SCOPE: any path under FEATURE or under .claude/agent-memory/ is admitted by rule, and [P0-T2] requires zero other paths at the start so the cycle's footprint claim rests on a known state. +- R1-D7 (AC scope). AC1 through AC6 are already checked in issue.md and remain untouched; [P0-T6] records that state and [P2-T4] proves it unchanged. Only AC7 is unmet and only AC7 is in scope. + +## Acceptance criteria inventory for this cycle + +AC7 (issue.md, `## Acceptance Criteria`): committed evidence follows the CLAUDE.md Committed Test Evidence Format and no committed file contains an absolute host path, the developer account name, or the host name. Closed by [P1-T1] through [P1-T5] (implementation), [P2-T1] and [P2-T2] (tests), and [P2-T4] (check-off). + +## Phases + +### Phase 0 — Baseline capture + +- [ ] [P0-T1] Read the policy files in order and record the read: CLAUDE.md, .claude/rules/general-code-change.md, .claude/rules/general-unit-test.md, .claude/rules/csharp.md, .claude/rules/plan-acceptance-gates.md, .claude/skills/atomic-plan-contract/SKILL.md, .claude/skills/evidence-and-timestamp-conventions/SKILL.md, .claude/skills/acceptance-criteria-tracking/SKILL.md, .claude/skills/remediation-handoff-atomic-planner/SKILL.md, then FEATURE/issue.md, FEATURE/remediation-inputs.2026-09-29T09-50.md and the three audit artifacts policy-audit.2026-09-29T00-45.md, code-review.2026-09-29T00-45.md and feature-audit.2026-09-29T00-45.md in FEATURE. Artifact EVIDENCE/remediation-baseline/r1-phase0-instructions-read.md with `Timestamp:` (CMD-TS), `Policy Order:` (the numbered list above), `Files Read:` (each path on its own line), `AC Source:` naming issue.md and quoting its `## Acceptance Criteria` heading verbatim, and `Work Mode:` quoting the `- Work Mode: minor-audit` line. Acceptance: the artifact exists with all five fields; the Grep tool finds the heading text `## Acceptance Criteria` in issue.md exactly once and the marker `- Work Mode: minor-audit` exactly once; the Glob tool over FEATURE returns no spec.md and no user-story.md (a hit halts the run as FAIL-CLOSED). +- [ ] [P0-T2] Record the tree anchors with CMD-ANCHOR. Artifact EVIDENCE/remediation-baseline/r1-tree-anchor.md with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:`, `R1-BASE:` (the 40-character `HEAD_SHA=` literal, which every later R1-BASE token substitutes), `Branch:`, `PreExistingWorktreePaths:` (the `STATUS` rows verbatim, relative paths only). Acceptance: `CWD_IS_TOPLEVEL=True`; `TOPLEVEL_LEAF=agent-ab7f72be619adf22f`; `BRANCH=bug/csharp-latent-hazards-uithread-ilglobals-comments-930`; `PORCELAIN_OUTSIDE_ALLOWED=0` (any path outside FEATURE and .claude/agent-memory/ halts BLOCKED, because the cycle's footprint claim would rest on an unknown starting state); no `STATUS` row names a path ending .cs, .csproj, .props, .targets, .sln, .runsettings or .config. Any other value halts BLOCKED. +- [ ] [P0-T3] Baseline measurement of the invariant with CMD-DRIVE-SCAN. Artifact EVIDENCE/remediation-baseline/r1-drive-scan-baseline.md with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:` carrying `SCAN_FILES:` and `HITS_TOTAL:` as printed, one row per printed `HIT` row in the form `FILE= LINE= MATCH=DRIVE-ROOTED-PATH` (the matched text is never transcribed; the printed row already carries none), and the printed control values. Acceptance: `HITS_TOTAL=7` and the seven hit rows are exactly: the baseline-04-mstest-coverage.md file under the evidence baseline directory at line 11; the final-06-mstest-coverage.md file under the evidence qa-gates directory at line 12; code-review.2026-09-29T00-45.md at line 18; policy-audit.2026-09-29T00-45.md at lines 182 and 188; feature-audit.2026-09-29T00-45.md at lines 39 and 53 (relative paths as printed, with backslash separators). Neither issue.md, remediation-inputs.2026-09-29T09-50.md, remediation-plan.2026-09-29T09-50.md nor any other file appears as a hit row. Controls: `SYNTHETIC_BACKSLASH_MATCH=True`, `SYNTHETIC_SLASH_MATCH=True`, `SYNTHETIC_URL_MATCH=False`, `CONTROL_LOG_HITS` at least 1 (the raw final coverage log carries drive-rooted paths, proving the pattern can match real data), `ISSUE_URL_LINES=1` (issue.md carries a URL line that does not match, proving the pattern does not over-match), `SCAN_FILES` at least 44. A different hit set, a failed control, or `CONTROL_LOG_HITS=0` halts BLOCKED with the printed values recorded. Record `BASELINE-SCAN-FILES:` from `SCAN_FILES=` for [P2-T1]. +- [ ] [P0-T4] Record the per-file state before any edit with CMD-FILE-STATE. Artifact EVIDENCE/remediation-baseline/r1-file-state-baseline.md with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:` carrying the six printed `FILE_STATE` rows verbatim (hashes and counts only). Acceptance: the six rows name, in order, the baseline-04 and final-06 evidence files, the code-review, policy-audit and feature-audit artifacts, and issue.md; `OCC` values are 1, 1, 1, 2, 2 and 1 (the seven drive-rooted install-path occurrences and the one open AC7 marker); `DRIVE_MATCHES` values are 1, 1, 1, 2, 2 and 0; `PLACEHOLDERS` is 0 in all six; `MASK_CHANGES_TEXT=True` in all six (the control that the in-memory edit changes each file); `RAW_TEXTHASH` differs from `MASKED_TEXTHASH` in all six. The six `MASKED_TEXTHASH` values are recorded as `EXPECTED-TEXTHASH-1:` through `EXPECTED-TEXTHASH-6:` in that order for [P1-T1] through [P1-T5] and [P2-T4]. Any other value halts BLOCKED. +- [ ] [P0-T5] Baseline of the executed plan's four-pattern gate with CMD-SANITIZE-R1. Artifact EVIDENCE/remediation-baseline/r1-sanitize-baseline.md recording counts only, never a matched value. Acceptance: `ACCOUNT_HITS=0`, `HOST_HITS=0`, `ROOT_HITS=0`, `DRIVE_USERS_HITS=0`, `RAW_TOOL_DOCS=0`, and the four controls `CONTROL_ACCOUNT_HITS`, `CONTROL_ROOT_HITS`, `CONTROL_HOST_HITS`, `CONTROL_DRIVE_HITS` each at least 1. The artifact states in one sentence that this is the root-cause observation: these four patterns read zero on the same tree on which [P0-T3] read seven hits, so they cannot detect a drive-rooted path outside a Users directory. A non-zero identity count halts BLOCKED, because the scope of this cycle would then be wider than NB-1. +- [ ] [P0-T6] Record the acceptance-criteria state of issue.md before the cycle with the Grep tool. Artifact EVIDENCE/remediation-baseline/r1-ac-baseline.md with `Timestamp:` and the counts `CHECKED-AC-LINES:`, `OPEN-AC-LINES:`, `OPEN-AC7-LINES:`. Acceptance: the Grep tool finds the fixed string `- [x] AC` (escaped for the Grep tool) on exactly 6 lines, the string `- [ ] AC` on exactly 1 line, and the string `- [ ] AC7:` on exactly 1 line, so the open item is AC7 and AC1 through AC6 are checked; any other count halts BLOCKED because the scope source no longer matches remediation-inputs.2026-09-29T09-50.md. + +### Phase 1 — Constrained remediation: placeholder substitution + +Each task below replaces the Visual Studio install directory prefix with VS-INSTALL-ROOT in one file and verifies, with CMD-FILE-STATE run after the edit, that nothing else in the file changed. Procedure for every substitution task: read the named line with the Read tool to obtain the exact install-root text (the drive letter, colon, separators, Program Files, Microsoft Visual Studio, the version directory and the edition directory, ending before the separator that precedes Common7); call the Edit tool on the named file with that text as `old_string`, VS-INSTALL-ROOT as `new_string` and `replace_all` true; never write the obtained text into an artifact, a command or this plan. The path that follows the install root (Common7 onward) stays in place. A `PROGRAM-FILES`-style placeholder form already present in a file has no drive prefix, so the search text does not match it and it is left as written. + +- [ ] [P1-T1] Substitute in FEATURE/evidence/baseline/baseline-04-mstest-coverage.md (line 11, one occurrence), then run CMD-FILE-STATE and write EVIDENCE/qa-gates/r1-subst-1.md with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:` carrying that file's printed `FILE_STATE` row. Acceptance: for the baseline-04 row, `RAW_TEXTHASH` equals `EXPECTED-TEXTHASH-1:` from [P0-T4], `PLACEHOLDERS=1`, `OCC=0`, `DRIVE_MATCHES=0`, and `LINES` equals the [P0-T4] value for that file. +- [ ] [P1-T2] Substitute in FEATURE/evidence/qa-gates/final-06-mstest-coverage.md (line 12, one occurrence), then run CMD-FILE-STATE and write EVIDENCE/qa-gates/r1-subst-2.md in the same form. Acceptance: for the final-06 row, `RAW_TEXTHASH` equals `EXPECTED-TEXTHASH-2:`, `PLACEHOLDERS=1`, `OCC=0`, `DRIVE_MATCHES=0`, `LINES` unchanged from [P0-T4]. +- [ ] [P1-T3] Substitute in FEATURE/code-review.2026-09-29T00-45.md (line 18, one occurrence, inside a backticked quotation), then run CMD-FILE-STATE and write EVIDENCE/qa-gates/r1-subst-3.md in the same form. Acceptance: for the code-review row, `RAW_TEXTHASH` equals `EXPECTED-TEXTHASH-3:`, `PLACEHOLDERS=1`, `OCC=0`, `DRIVE_MATCHES=0`, `LINES` unchanged from [P0-T4]. This file is edited only by the substitution (Decision R1-D4). +- [ ] [P1-T4] Substitute in FEATURE/policy-audit.2026-09-29T00-45.md (lines 182 and 188, two occurrences, so `replace_all` is required), then run CMD-FILE-STATE and write EVIDENCE/qa-gates/r1-subst-4.md in the same form. Acceptance: for the policy-audit row, `RAW_TEXTHASH` equals `EXPECTED-TEXTHASH-4:`, `PLACEHOLDERS=2`, `OCC=0`, `DRIVE_MATCHES=0`, `LINES` unchanged from [P0-T4]. +- [ ] [P1-T5] Substitute in FEATURE/feature-audit.2026-09-29T00-45.md (lines 39 and 53, two occurrences, so `replace_all` is required), then run CMD-FILE-STATE and write EVIDENCE/qa-gates/r1-subst-5.md in the same form. Acceptance: for the feature-audit row, `RAW_TEXTHASH` equals `EXPECTED-TEXTHASH-5:`, `PLACEHOLDERS=2`, `OCC=0`, `DRIVE_MATCHES=0`, `LINES` unchanged from [P0-T4]. +- [ ] [P1-T6] Footprint gate: run CMD-FOOTPRINT with R1-BASE substituted. Artifact EVIDENCE/qa-gates/r1-footprint.md with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:` carrying the printed counts and `OUTSIDE_PATH`, `INSIDE_PATH` and `STATUS` rows (relative paths only). Acceptance: `OUTSIDE_TRACKED_CHANGES=0` (the cycle changes no tracked file outside FEATURE and .claude/agent-memory/); `PORCELAIN_OUTSIDE_ALLOWED=0`; `INSIDE_TRACKED_CHANGES` is at least 2 (the positive control that the anchored diff sees tracked edits: the two pre-existing evidence files are tracked and were just edited) and every `INSIDE_PATH` row names one of the five substituted files or the file remediation-plan.2026-09-29T09-50.md (the plan file appears only when it was already tracked at R1-BASE and carries check-off marks); `PORCELAIN_IN_FEATURE` is at least 1 (the positive control that the porcelain filter sees the new untracked r1 artifacts). A path outside the allowed scope halts BLOCKED. + +### Phase 2 — Final verification, acceptance check-off, commit and push + +- [ ] [P2-T1] Re-run the general drive-rooted scan with CMD-DRIVE-SCAN over the whole of FEATURE. Artifact EVIDENCE/qa-gates/r1-drive-scan-final.md with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:` carrying the printed values. Acceptance: `HITS_TOTAL=0` (no file in FEATURE contains a drive-rooted path, including this plan, issue.md, every evidence file and every audit artifact); `SYNTHETIC_BACKSLASH_MATCH=True`, `SYNTHETIC_SLASH_MATCH=True`, `SYNTHETIC_URL_MATCH=False`; `CONTROL_LOG_HITS` at least 1 (the pattern still matches real data, so zero hits is not vacuous); `ISSUE_URL_LINES=1`; `SCAN_FILES` is at least `BASELINE-SCAN-FILES:` from [P0-T3] plus 10 (ten artifacts are written after the [P0-T3] scan and are inside the scanned set: the four r1 artifacts of [P0-T3] through [P0-T6], the five substitution artifacts of [P1-T1] through [P1-T5], and the footprint artifact of [P1-T6]). Any hit row is remediated by the placeholder substitution of the offending file and the run restarts at [P2-T1]; this task cannot complete with a non-zero hit count. +- [ ] [P2-T2] Re-run the executed plan's four sanitize patterns with CMD-SANITIZE-R1. Artifact EVIDENCE/qa-gates/r1-sanitize-final.md recording counts only. Acceptance: `ACCOUNT_HITS=0`, `HOST_HITS=0`, `ROOT_HITS=0`, `DRIVE_USERS_HITS=0`, `RAW_TOOL_DOCS=0`, and the four controls `CONTROL_ACCOUNT_HITS`, `CONTROL_ROOT_HITS`, `CONTROL_HOST_HITS`, `CONTROL_DRIVE_HITS` each at least 1. A non-zero count is remediated by placeholder substitution in the offending file and both [P2-T1] and this task are re-run. +- [ ] [P2-T3] Record why no C# toolchain run is required. Run CMD-EXTENSIONS with R1-BASE substituted. Artifact EVIDENCE/qa-gates/r1-toolchain-exemption.md with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:` carrying the printed counts and one statement that the format, analyzer, nullable and MSTest-with-coverage steps are not run because the cycle diff holds no C# source, test, project, props, targets, solution, runsettings or configuration file, citing r1-footprint.md (`OUTSIDE_TRACKED_CHANGES=0`) as the footprint proof. Acceptance: `CODE_OR_CONFIG_TRACKED_CHANGES=0`, `CODE_OR_CONFIG_PORCELAIN=0`, and `CONTROL_MD_PORCELAIN` at least 1 (the porcelain filter sees the markdown artifacts, so zero code paths is not a blind filter). Any non-zero code or configuration count halts BLOCKED. +- [ ] [P2-T4] Check off AC7 in FEATURE/issue.md on verified evidence. First confirm the conditions: r1-drive-scan-final.md shows `HITS_TOTAL=0` with the controls met, r1-sanitize-final.md shows its five zero counts with four controls at least 1, r1-subst-1.md through r1-subst-5.md each show `RAW_TEXTHASH` equal to its expected value, and r1-toolchain-exemption.md shows both zero counts. If every condition holds, use the Edit tool to change exactly the text `- [ ] AC7:` to `- [x] AC7:` in FEATURE/issue.md (no criterion wording changes), then run CMD-FILE-STATE and write EVIDENCE/qa-gates/r1-ac-status.md with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:`, and the line `AC7: MET` citing r1-drive-scan-final.md, r1-sanitize-final.md, r1-subst-1.md through r1-subst-5.md and r1-footprint.md. Acceptance: the issue.md `FILE_STATE` row has `RAW_TEXTHASH` equal to `EXPECTED-TEXTHASH-6:` from [P0-T4] (only the AC7 marker changed), `OCC=0`; the Grep tool finds the fixed string `- [x] AC` on exactly 7 lines and `- [ ] AC` on 0 lines. If any confirming condition fails, leave issue.md untouched, write `AC7: NOT MET` naming the failing value in r1-ac-status.md, and halt BLOCKED. +- [ ] [P2-T5] Commit in the exempt form. Before staging, re-run CMD-DRIVE-SCAN (with its Set-Location prefix) and require `HITS_TOTAL=0` and `CONTROL_LOG_HITS` at least 1 (this re-run covers the artifacts written after [P2-T1], and its counts are reported in the executor's return with no artifact written). Then run `git -C WORKTREE-ROOT add -- docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930` and then `git -C WORKTREE-ROOT commit -m "docs(930): remediation cycle 1 replace absolute install path with VS-INSTALL-ROOT placeholder and check off AC7 Co-Authored-By: Claude Opus 5.5 noreply@anthropic.com" -m "Claude-Session: https://claude.ai/code/session_01KNZiXntshsLY8vqqCHUvHm" -- docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930`, then `git -C WORKTREE-ROOT diff --name-only R1-BASE HEAD -- .

No artifact is written by this task; the resulting SHA is reported in the executor's return. Acceptance: the pre-stage scan reads `HITS_TOTAL=0`; the commit exits 0; the anchored diff prints nothing (no file outside FEATURE and .claude/agent-memory/ differs between R1-BASE and HEAD); the post-commit porcelain span over FEATURE is empty or names only this plan file (whose own check-off marks land after the commit). +- [ ] [P2-T6] Commit this plan file's check-off marks and push the branch. Mark every completed task in this plan `[x]` (including this one), then run `git -C WORKTREE-ROOT status --porcelain -- docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930`; if it names this plan file, run `git -C WORKTREE-ROOT commit -m "docs(930): remediation cycle 1 plan check-off Co-Authored-By: Claude Opus 5.5 noreply@anthropic.com" -m "Claude-Session: https://claude.ai/code/session_01KNZiXntshsLY8vqqCHUvHm" -- docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930/remediation-plan.2026-09-29T09-50.md` (the plan file only; no `git add -A`). Then run `git -C WORKTREE-ROOT push origin bug/csharp-latent-hazards-uithread-ilglobals-comments-930`, then `git -C WORKTREE-ROOT rev-parse HEAD` and `git -C WORKTREE-ROOT ls-remote origin refs/heads/bug/csharp-latent-hazards-uithread-ilglobals-comments-930`. No artifact is written by this task. Report in the executor's return the Acceptance Criteria Status block (`Source:` issue.md, `Total AC items: 7`, `Checked off (delivered):`, `Remaining (unchecked):`), every commit SHA made in this cycle, and the commands run with their results, stating that no C# toolchain step was run because [P2-T3] and [P1-T6] prove the cycle diff holds no C# or configuration file. Acceptance: the push exits 0; the first field of the `git ls-remote` output equals the `git rev-parse HEAD` output; `git status --porcelain -- docs/features/active/2026-09-28-csharp-latent-hazards-uithread-ilglobals-comments-930` names nothing.

AC7 has been unchecked in issue.md. - Remedy: replace the path prefix on both lines with a placeholder (for example `PROGRAM-FILES\Microsoft Visual Studio\18\Community\...` or the token `VSTEST-CONSOLE`), commit in the exempt docs-only form, and re-check AC7.

Procedure for every substitution task: read the named line with the Read tool to obtain the exact install-root text (the drive letter, colon, separators, Program Files, Microsoft Visual Studio, the version directory and the edition directory, ending before the separator that precedes Common7); call the Edit tool on the named file with that text as `old_string`, VS-INSTALL-ROOT as `new_string` and `replace_all` true; never write the obtained text into an artifact, a command or this plan. The path that follows the install root (Common7 onward) stays in place.

The cycle-1 change is documentation only: seven path-prefix substitutions with the placeholder `VS-INSTALL-ROOT` in five files (two committed evidence summaries and the quotations inside the three 2026-09-29T00-45 audit artifacts). The Non-blocking finding from the prior review (absolute install path in committed evidence, contradicting AC7) is resolved: a Grep of the whole feature folder for `\b[A-Za-z]:[\\/]\S` returns zero matches, and the same pattern returns 26 matches on the raw coverage log, so the zero is not a blind pattern.

Neither difference changes the counts: Blocking 0, Non-blocking 0, Informational 9. + +## Detailed Review + +### Cycle 1 documentation edits (new in this re-audit) + +- Placeholder counts read by Grep for `VS-INSTALL-ROOT`: baseline-04-mstest-coverage.md 1, final-06-mstest-coverage.md 1, code-review.2026-09-29T00-45.md 1, policy-audit.2026-09-29T00-45.md 2, feature-audit.2026-09-29T00-45.md 2. Together with the substitution records this equals the seven baseline hit rows in r1-drive-scan-baseline.md. The remaining Grep hits for the placeholder are in the remediation plan, remediation inputs and r1 evidence files, which describe the placeholder without any path. +- The two evidence summaries were re-read: line 11 (baseline) and line 12 (final) now read `Runner output: Using vstest.console: VS-INSTALL-ROOT\Common7\IDE\Extensions\TestPlatform\vstest.console.exe; Discovered 9 test assemblies.`. The adjacent figures are intact: baseline `lines 56079/65737 (85.31%), branches 13593/17052 (79.71%)`, `Total tests: 7320. Passed: 7320.`; final `lines 56084/65736 (85.32%), branches 13597/17054 (79.73%)`, `Total tests: 7322. Passed: 7322.`. +- The hash chain (r1-file-state-baseline.md, r1-subst-1 to r1-subst-5) is a sound proof of text-exactness. The expected hash is derived from the pre-edit text by applying only the path-prefix regular expression, so a post-edit hash equal to it excludes any other edit. Line counts equal the baseline values (229, 230, 64, 270, 68). The path mask is narrow (a drive letter, `Program Files`, `Microsoft Visual Studio`, two path segments, lookahead `Common7`), so it cannot rewrite unrelated text. +- The gate is non-vacuous: synthetic backslash and slash paths match, a URL does not, and the raw log yields 26 hits (baseline and final), matching the reviewer's independent control of 26. +- The cycle also edits the three prior audit artifacts in place, replacing quoted path text. That is appropriate here: the quotations were themselves committed AC7 violations, and the edit changes no verdict, count or finding text. +- issue.md: only the AC7 marker changed (hash equals EXPECTED-TEXTHASH-6, r1-ac-status.md). Reviewer read of issue.md confirms `[x]` on AC1 to AC7 (lines 44 to 50) and no other change to criterion text. +- Root-cause treatment: the prior gate enumerated identity patterns (account, host, worktree root, drive-rooted Users directory). The remediation states the invariant (no drive-rooted path anywhere in the folder) and gates on a general pattern with a positive control, which is the correct fix rather than adding one more named directory. + +### UtilitiesCS/Threading/UiThread.cs (unchanged; spot-verified) + +Reviewer Grep finds `&& _dispatcher is not null` at line 184 (captured-context exit) and line 199 (dispatcher exit), the same operand shape in both exits. With `_dispatcher` null and no dispatcher on the executing thread, the former `ReferenceEquals(null, null)` evaluated true; the added conjunct removes that path and can only make the exit more restrictive. The prior audit confirmed all twelve pre-existing `IsCompleted` tests still pass and the nullable Rebuild reports 0 CS86xx. + +### UtilitiesCS/NewtonsoftHelpers/SDIL Reader/ILGlobals.cs (unchanged; spot-verified) + +Reviewer Grep over `*.cs` for a remaining `Cache` or `modules` reference or public static declaration returns zero matches.

The two #863 tests assert non-empty init-only public statics and the exact name set. All three were recorded failing before the fix and passing after. No `DoNotParallelize`, worker-count, retry, sleep or temporary-file change (`ADDED_*=0`, runsettings hash unchanged). + +### Introduced-by-cycle check + +Checked and none found: no tracked change outside the feature folder and `.claude/agent-memory/` (`OUTSIDE_TRACKED_CHANGES=0`, `PORCELAIN_OUTSIDE_ALLOWED=0`); no code or configuration path (`CODE_OR_CONFIG_TRACKED_CHANGES=0`, `CODE_OR_CONFIG_PORCELAIN=0`, control 24 markdown rows); no drive-rooted path in any new artifact (whole-folder Grep zero, including the plan, remediation inputs and all r1 files); no account, host or worktree-root disclosure (r1-sanitize-final.md zeros with controls).

Blocking: 0. Non-blocking: 0. Informational: 9 (carried forward).** + +The prior audit's single Non-blocking finding (NB-1, absolute Visual Studio install path on two committed evidence lines and in the quotations of the three prior audit artifacts) is resolved. Verified by this reviewer: a Grep over the whole feature folder for the drive-rooted pattern `\b[A-Za-z]:[\\/]\S` returns zero matches, and the same pattern returns 26 matches against the gitignored raw coverage log (independent positive control). The five substituted files carry the placeholder `VS-INSTALL-ROOT` (evidence files: one occurrence each; policy-audit: two; feature-audit: two; code-review: one). Each substitution is proven text-exact: the pre-edit masked hash (r1-file-state-baseline.md, computed by applying only the path-prefix regex to the pre-edit text) equals the post-edit raw hash in r1-subst-1 to r1-subst-5, and line counts are unchanged (229, 230, 64, 270, 68). No tracked change exists outside the feature folder and `.claude/agent-memory/`, and no C# source, test, project, props, targets, solution, runsettings or configuration file changed in the cycle. AC7 is therefore met and remains checked in issue.md; AC1 to AC6 rest on unchanged evidence and still pass. + +The code diff and its toolchain evidence are those of the prior audit: CSharpier check over 1623 files exit 0, analyzer Rebuild 0 errors and 0 warnings, TreatWarningsAsErrors Rebuild 0 errors, 7322 of 7322 tests passed, first-party coverage 85.31% lines / 79.71% branches to 85.32% lines / 79.73% branches, changed executable line covered.

Unchanged by the cycle. | +| Isolation | PASS | Each new test targets one predicate exit or one structural property. | +| Fast execution | PASS | No sleeps, delays or retries added (`ADDED_Thread.Sleep=0`, `ADDED_Task.Delay=0`, `ADDED_Retry=0`). | +| Determinism | PASS | Test-owned STA dispatcher host and MTA thread, joined; no wall-clock waits; no temporary files. | +| Readability | PASS | Descriptive names, XML summaries, Arrange/Act/Assert comments. | + +### 1.2 Coverage and Scenarios + +**Coverage Metrics by Language:** + +| Language | Files Changed | Tests | Test Result | Baseline Coverage | Post-Change Coverage | New Code Coverage | +|---|---|---|---|---|---|---| +| C# | 6 | 7322 | 7322 passed / 0 failed | 85.31% lines / 79.71% branches | 85.32% lines / 79.73% branches | 100% lines (1 of 1 changed executable line) | +| TypeScript | 0 | N/A | N/A | N/A | N/A | N/A | +| Python | 0 | N/A | N/A | N/A | N/A | N/A | +| PowerShell | 0 | N/A | N/A | N/A | N/A | N/A | + +C# coverage verdict: PASS (repo-wide first-party 85.32% lines and 79.73% branches; UiThread.cs 97.76%, ILGlobals.cs 94.74%; changed-line coverage 100%; no regression on changed lines). The cycle did not touch any C# file, so the coverage evidence (evidence/baseline/baseline-04-mstest-coverage.md, evidence/qa-gates/final-06-mstest-coverage.md and the two package-level JaCoCo projections) is unchanged in every figure; the only change to the two summary files is the path-prefix text on one line each, proven by hash equality (r1-subst-1, r1-subst-2). Figures in both files re-read by this reviewer: baseline `lines 56079/65737 (85.31%), branches 13593/17052 (79.71%)`; final `lines 56084/65736 (85.32%), branches 13597/17054 (79.73%)`. + +Per-file detail (unchanged; transcribed in the two evidence summaries): + +- `UtilitiesCS/Threading/UiThread.cs`: 130/133 (97.74%) to 131/134 (97.76%); uncovered lines 38, 39, 40 in both runs; changed operand line has HITS=1; condition coverage on the return expression 2/2 to 4/4. +- `UtilitiesCS/NewtonsoftHelpers/SDIL Reader/ILGlobals.cs`: 38/40 (95.00%) to 36/38 (94.74%); deletion-only diff, uncovered count 2 in both runs; the percentage change is arithmetic (two covered initializer lines deleted), not a changed-line regression. +- Two QuickFiler `.Search.cs` files: comment-only edits. + +Method note (Decision D3): four shell-icon test classes were excluded identically from both local coverage runs; CI runs them unfiltered. The exclusion is a test-selection filter, not a coverage `exclude` entry on a production path, so the Coverage Exclusion Policy blocking rule is not engaged. + +### Coverage Evidence Checklist + +- C# baseline coverage artifact: `evidence/baseline/baseline-coverage.jacoco.xml` plus `evidence/baseline/baseline-04-mstest-coverage.md` +- C# post-change coverage artifact: `evidence/qa-gates/final-coverage.jacoco.xml` plus `evidence/qa-gates/final-06-mstest-coverage.md` +- TypeScript baseline coverage artifact: `N/A - zero TypeScript files changed on this branch` +- TypeScript post-change coverage artifact: `N/A - zero TypeScript files changed on this branch` +- PowerShell baseline coverage artifact: `N/A - zero PowerShell files changed on this branch` +- PowerShell post-change coverage artifact: `N/A - zero PowerShell files changed on this branch` +- Python baseline coverage artifact: `N/A - zero Python files changed on this branch` +- Python post-change coverage artifact: `N/A - zero Python files changed on this branch` +- Per-language comparison summary: section 1.2.1 of this document + +Note on the canonical artifact path: `artifacts/csharp/coverage.xml` does not exist in the review worktree, and CLAUDE.md prohibits committing the raw Cobertura document.
