A stale marker for a finished prime is then left in `_primeTasks`, which blocks any later re-prime for that engine. This is hazard B from the #942 research, first recorded as NB-2 in the #735 code review, and never promoted. + +## Environment + +- OS/version: Windows 11 / windows-latest +- Python version: n/a (C#, .NET Framework 4.8) +- Command/flags used: n/a (production code path; also reachable from the re-prime in `GetPressed_WhenPrimeFaults_LogsErrorAndStillReturnsFalse`) +- Data source or fixture: n/a + +## Steps to Reproduce + +1. Arrange for `EngineActiveAsync` to return an already-faulted task, for example after a cached configuration-load fault. +2. Call `GetPressed` for that engine, which triggers `StartPrimeIfNeeded`. +3. `StartObservedPrime` schedules the continuation. The continuation can run `CompletePrime` (`_primeTasks.TryRemove`, line ~348) before the assignment `_primeTasks[engineName] = ...` at line ~276 stores it. + +## Expected Behavior + +A finished prime never leaves a marker in `_primeTasks`, so a later `GetPressed` can start a fresh prime. + +## Actual Behavior + +The removal can precede the registration.

Registration happens after the continuation is scheduled, so a continuation that finishes quickly can remove the marker before it is written. No current test fails on this. #942 fixes a different ordering (log before removal) and leaves this one out of scope by design. + +## Proposed Fix / Validation Ideas + +- [ ] Write a deterministic regression test: use a pre-faulted `EngineActiveAsync` and assert that a second `GetPressed` starts a new prime. It must fail before the fix. +- [ ] Fix options: register a placeholder before scheduling, or make removal conditional on the stored task being the completing one (`TryRemove` with a `KeyValuePair` comparison), or take `_primeGate` in `CompletePrime`. +- [ ] Use no sleeps, retries, `[DoNotParallelize]` or Workers=1. + +## Next Step + +- [x] Promote to GitHub issue (bug-report template) +- [ ] Move to active fix folder / branch diff --git a/docs/features/active/2026-09-30-engine-toggle-prime-marker-registration-races-removal-944/plan.2026-09-30T07-20.md b/docs/features/active/2026-09-30-engine-toggle-prime-marker-registration-races-removal-944/plan.2026-09-30T07-20.md new file mode 100644 index 000000000..55faf6d2b --- /dev/null +++ b/docs/features/active/2026-09-30-engine-toggle-prime-marker-registration-races-removal-944/plan.2026-09-30T07-20.md @@ -0,0 +1,984 @@ +# 2026-09-30-engine-toggle-prime-marker-registration-races-removal (Plan) + +- **Issue:** #944 +- **Parent (optional):** none +- **Owner:** drmoisan +- **Work Mode:** full-bug (acceptance criteria come from `docs/features/active/2026-09-30-engine-toggle-prime-marker-registration-races-removal-944/spec.md` only; no user story exists for this item and none is to be authored) +- **Last Updated:** 2026-09-30T14-00 +- **Status:** Ready for preflight (revision round 2) +- **Version:** 1.2 +- **Revision record:** version 1.0, initial authoring: the planner amended the spec's AC14 and AC15 (and the sibling toolchain sentence in the Test Strategy) and advanced the spec header to version 1.1 (decision D-12). Version 1.1, preflight round 1 (twelve defects, deltas D1 to D12): P0-T4 admits the `STAGED-NEW` promotion-record state (D1); P0-T5 gains an upstream-overlap stop and a `MERGE_HEAD`-guarded abort (D2); P1-T2's exact-entry count builds its double quotes from a character code (D3); D-10 fixes the attribution-trailer form (D4); P0-T4, P0-T20 and P2-T8 run the P3-T13 hygiene sweep before staging (D5), and the same pre-commit sweep was extended to P3-T35 because the artifacts P3-T15 to P3-T34 write land after P3-T13; the issue 780 re-run became a single pass-2 restart of P3-T1 to P3-T8 (D6); spec AC14, the Test Strategy step 4 sentence, D-7 and D-12 name the vstest hang-blame switch on the DIRECT route, and the spec header advanced to version 1.2 (D7; the AC14 words "Phase 0" became "baseline" so the AC line carries no digit other than its label); P2-T8 stops when the formatter re-splits a repaired token (D8); every check-off task appends its line to the status summary, which P3-T33 completes (D9); the P0-T18 `Output Summary:` is bounded to 20 lines with a `Details:` section (D10); P3-T3's expected partial size, self-review finding 4 and the E3 remarks word were corrected (D11); git commands without -C are run with -C WORKTREE (D12). No acceptance criterion was added, removed or renumbered. Version 1.2, preflight round 2 (three defects, deltas R1 to R3; D1 to D12 confirmed): the Git working directory convention fixes the form of the -C operand and bars a dollar sign, a backtick and an angle bracket from any exempt git add or git commit line (R1); region set `PROTECTED` gains `PRIMETASKS-DECLARATION` over the `_primeTasks` declaration, the paragraph after the region sets names the non-edited lines no region verifies (minimally corrected to include the blank line after the E3 block, which the supplied text omitted), the region-set heading no longer claims a partition, and P2-T7's title and row list name the new region (R2); P3-T8's re-run rule rewrites the top-level fields of the coverage summary with pass 2's values and keeps the first attempt's exit code as `FIRST-ATTEMPT-EXIT-CODE:`, and records why no other pass-2 artifact needs the same rewrite (R3).

After #942 (its approved plan's Delivered Source): the `GetPrimeTask` `returns` element grows by two lines and gains the token `cleared only after that report has returned`; the `CompletePrime` summary is rewritten; in the `CompletePrime` body the `_logError(BuildPrimeFailedMessage(engineName), failure);` statement precedes `_primeTasks.TryRemove(engineName, out _);` with a comment beginning `Report-then-clear is load-bearing` above it. #942 edits nothing between line 1 and the `GetPrimeTask` `returns` element, nothing in `StartPrimeIfNeeded` or `StartObservedPrime`, and nothing in `ApplyPrimeAsync`. Every line number in fact 1 at or after 242 therefore shifts after the merge; P0-T6 to P0-T8 re-derive every position this plan uses, and every later gate locates code by single-occurrence tokens or by relations between re-read positions, never by a line number written here. +3.

At PREP-SHA `TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.Race.cs` is 277 content lines with no `[TestClass]` and usings System, System.Threading.Tasks, FluentAssertions, Microsoft.VisualStudio.TestTools.UnitTesting and Moq; it uses `SetupSequence(x => x.EngineActiveAsync(SpamEngine))` (44 to 47) and `.BeAssignableTo(` (227), the precedents the new partial follows. +5. At PREP-SHA `TaskMaster.Test/TaskMaster.Test.csproj` carries `` at 352 and `` at 359, followed by the EngineTogglePressedStateCacheTests entry at 360. #942 inserts its PrimeFaultOrdering entry immediately after the Race entry. The new entry of this plan is inserted immediately after the PrimeFaultOrdering entry, whose line P0-T8 re-derives. Explicit compile items: an unlisted file is not compiled. .csharpierignore line 12 excludes project files from the formatter. +6. `RunContinuationsAsynchronously` is already used in production at TaskMaster/AppGlobals/NonBlockingDelay.cs line 68 and TaskMaster/AppGlobals/AppOlObjects.FolderTreeService.cs line 52; NonBlockingDelay.cs 67 to 69 shows the layout CSharpier gives a `new TaskCompletionSource(` construction whose single argument does not fit the line. +7. `docs/features/potential/promoted/2026-09-30-engine-toggle-prime-marker-registration-races-removal.md` exists in this worktree with `Status: Promoted` at line 5 and `Issue: #944` at line 9. The worktree HEAD and the branch ref both equal PREP-SHA and carry no commit of this item yet, so whether the record is tracked cannot be read without git in the planning session; P0-T4 observes its state and commits it when it is untracked, staged-new or modified. Orchestrator fact recorded at revision round 1: the record is currently staged as a new file because it was restored with a path-scoped checkout from the branch, and the orchestrator commits it with the feature folder at the end of preparation, so the expected execution-time state is `TRACKED-UNCHANGED`; P0-T4 nevertheless admits every state. +8. scripts/vscode/Invoke-MSTestWithCoverage.ps1 defines `ConvertTo-DerivedCoverageSettingsXml` (97) and dot-sources Invoke-MSTestWithCoverage.Helpers.ps1 (303) and Invoke-MSTest.TrxSummary.ps1 (309); Helpers.ps1 dot-sources the ClosureFilter, PackageRate, Threshold, FirstParty and Projection scripts (2 to 6) and defines `Get-CoberturaClassLineSummary` (160; LineMap keyed by line number with Hits, TotalLines, CoveredLines, TotalBranches, CoveredBranches at 252 to 256), `Merge-CoberturaClassesByFilename` (260) and `ConvertTo-KoverageCoberturaXml` (407). Threshold.ps1 defines `Assert-CoberturaLineCoverageThreshold` (3) and `Assert-CoberturaBranchCoverageThreshold` (58); FirstParty.ps1 `Get-CoberturaFirstPartyCoverageReport` (123); Projection.ps1 `ConvertTo-JacocoPackageProjection` (14) and `Assert-JacocoProjectionReconciliation` (83); TrxSummary.ps1 `Get-TrxRunSummary` (12) and `Format-TrxRunSummary` (103). ClosureFilter.ps1 removes closure-type coverage only when the declaring member is absent from the report (235), so the lambda body inside `StartObservedPrime` stays measured and is merged into the file's single class node. +9. .gitignore ignores `*.trx` (146), `*cobertura*.xml` (147) and the coverage directory (150) with a `.gitkeep` re-include (151); coverage\.gitkeep is present. .csharpierignore excludes the evidence tree (4), cobertura, coverage, coveragexml and trx files (5 to 8), csproj, props and targets (12 to 14), packages.config (16) and app.config (18). global.json, dotnet-tools.json, coverage.config, scripts/vscode/Install-RepoDotNetSdk.ps1, scripts/vscode/Invoke-Restore.ps1 and scripts/hygiene/Test-RepositoryHygiene.Rules.ps1 exist. +10. .claude/hooks/validate-planner-output.ps1 line 95 requires a separator-bearing path token on each task's opening line. +11. Host constraint carried from the sibling #931 and #942 plans: four UtilitiesCS.Test shell-icon test classes (`HelperClasses.ShellUtilities_Tests`, `HelperClasses.ShellUtilitiesStatic_Tests`, `HelperClasses.SysImageListHelperTests`, `EmailIntelligence.OSBrowser_Tests`) have stalled vstest on this workstation; CI executes them. Whether the stall reproduces is unknown, so P0-T16 measures it and the result selects the coverage route (D-7). +12. The .dotnet-sdk, packages and bin trees are git-ignored and were not observable from the planning session (a miss is inconclusive), so every bootstrap task is guarded and gated on its post-task marker. + +## Design decisions (do not redesign) + +- **D-1 Fix shape (research 3 (iii)).** In `StartPrimeIfNeeded`, inside the existing `lock (_primeGate)` block and after the `ContainsKey` check, a `TaskCompletionSource` marker created with `TaskCreationOptions.RunContinuationsAsynchronously` is stored with `_primeTasks[engineName] = marker.Task;` and only then is `StartObservedPrime(engines, engineName, controlId, marker);` called, under a why-comment naming issue 944. `StartObservedPrime` returns void, receives the marker, discards the continuation with `_ =`, keeps `CancellationToken.None`, `TaskContinuationOptions.None` and `TaskScheduler.Default`, and its continuation body is a `try` around `CompletePrime(completed, engineName);` with `marker.SetResult(true);` in the `finally`. No `catch`, no lock, no scheduler seam, no `ExecuteSynchronously`. The full texts are in the Delivered Source section. +- **D-2 CompletePrime and ApplyPrimeAsync are frozen.** The `CompletePrime` summary, remarks and body (report-then-clear, owned by #942) and the whole `ApplyPrimeAsync` method are not edited. P2-T7 proves it by comparing the region from the `ApplyPrimeAsync` summary through the `CompletePrime` closing brace against the anchor. +- **D-3 GetPrimeTask documentation is not edited.** Given the #942 delivered text, each sentence was re-read against the new design. The summary ("The in-flight — or most recently completed — prime for an engine key, exposed so tests can await the prime deterministically instead of polling or sleeping.") stays true: the returned value is the handle of that prime and completes when the prime's outcome has been observed. The first `returns` sentence ("The prime task, or Task.CompletedTask when no prime has been started for the key.") stays true to the same extent as before: the marker is the task that represents the prime, and the #942 sentence already qualifies the failure path. The second ("The returned task never faults: a prime fault is observed inside the prime itself and reported through logError.") becomes stronger, because the marker is completed only by `SetResult`. The #942 sentence ("For a key whose prime did not run to completion, the marker is cleared only after that report has returned, so a caller that receives Task.CompletedTask can rely on the fault having been reported.") stays true, because the `finally` completes the marker after `CompletePrime` has reported and removed. No sentence names the continuation task, so none has become false and no replacement text is needed. P0-T7 fails closed: if the anchored `GetPrimeTask` documentation contains the word continuation, or lacks the #942 token `cleared only after that report has returned`, the run stops with `GETPRIMETASK DOC DIVERGES` for re-planning. P2-T7 proves the method is byte-identical to the anchor. +- **D-4 New partial.** `TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.PrimeRegistration.cs` follows the Race partial's shape: no `[TestClass]`, usings System, System.Threading, System.Threading.Tasks, FluentAssertions, Microsoft.VisualStudio.TestTools.UnitTesting and Moq (for `Times`), one region, three `[TestMethod]` methods, each constructing its own `Harness`, no new Harness member and no new mock. The program-order test initialises `handleCompletedDuringRead` to true, so a setup callback that never runs fails the first assertion (spec Risks). Its compile entry is inserted immediately after the PrimeFaultOrdering entry. +- **D-5 Fail-before is a real run.** The partial uses only `internal` API present at the anchor, so it compiles against the unchanged production file, and P1-T4 runs it before any production edit. Test 1 fails by program order on its first assertion: before the fix no entry exists while `EngineActiveAsync` runs, so the recorded handle is `Task.CompletedTask`, which is complete. The failing message carries the reason fragment `must be registered before the activation read runs`, which no other assertion in the fixture carries, so a compile error, an assembly-load failure or a timeout cannot produce it. Tests 2 and 3 fail before the fix only when a pool thread wins the race; their pre-fix outcome is recorded without a gate. +- **D-6 Anchor and substitution rule.** P0-T5 records `ANCHOR-SHA:` as the output of `git merge-base origin/main HEAD` after merging origin/main, and requires it to equal `git rev-parse origin/main`. Wherever the literal ANCHOR-SHA appears in a command or payload of this plan, the executor substitutes that recorded 40-character value; wherever PREP-SHA appears, it substitutes `231e1c0b55105aeb626bf5a6e8d0266a567cacad`. Paths changed between the anchor and HEAD at P0-T5 form the inherited set (`INHERITED-COMMITTED:`), which may contain only feature-folder paths and the promotion record. +- **D-7 Coverage route is selected by a recorded observation.** P0-T16 runs the four shell-icon classes alone and records `STALL-PROBE: CLEAR` or `REPRODUCES`. `COVERAGE-ROUTE: RUNNER` (CLEAR) runs scripts/vscode/Invoke-MSTestWithCoverage.ps1 verbatim (CLAUDE.md step 4). `COVERAGE-ROUTE: DIRECT` (REPRODUCES) issues the runner's own inner collector invocation with those four test classes excluded and the vstest hang-blame switch appended, post-processed with the runner's own helpers, because the runner hard-codes its test-case filter. Both routes yield the same committed forms: the `First-party coverage:` line, the JaCoCo package projection text, the trx-derived summary and the per-method coordinator figures, all transcribed into Markdown. Under DIRECT the CLAUDE.md floors are applied by the runner's own threshold functions and a NOT MET result is treated as a runner failure. The amended AC14 names both routes (D-12). +- **D-8 Per-method coverage figure (how a third party obtains the same number).** From the post-processed Cobertura document, take the single `class` element whose `filename` attribute, after replacing backslashes with forward slashes, ends with `TaskMaster/Ribbon/EngineToggleStateCoordinator.cs`, and reduce it with `Get-CoberturaClassLineSummary` (the deduplicated line map, keyed by line number, taking the maximum hits across the class-level and method-level views). A method's span runs from the first source line matching eight spaces, `private`, a return type and the method name followed by an opening parenthesis, through the first following line that is exactly eight spaces and a closing brace. The method's line coverage is 100 times the number of line-map entries inside the span with hits at least 1, divided by the number of line-map entries inside the span, rounded to two decimals. Lambda bodies inside the span (the continuation in `StartObservedPrime`) are included because the closure filter keeps them and the merge places them in the same class node (fact 8). +- **D-9 Repository-wide rate is recorded under a comparability rule.** The merged repository line rate is not reproducible across runs of an identical tree. P3-T10 compares it in two branches: `COMPARABLE` when the two root lines-valid figures differ by at most 1 percent of the baseline figure (then the final root line-rate must be at least the baseline root line-rate minus 0.005), otherwise `INCOMPARABLE` (recorded, not gated, with a one-sentence reason). The no-regression weight rests on the per-file, per-method and per-changed-line figures, which the merge does not perturb. The amended AC15 states this rule (D-12). +- **D-10 Commits.** Five commits, each `git add -- ` then a separate `git commit`, one command per invocation, never chained, never `git add -A`: P0-T4 (feature folder and promotion record, before the merge, so an untracked copy cannot block the merge), P0-T5 (the merge commit, when a merge is needed), P0-T20 (feature folder), P2-T8 (the three code files and the feature folder, staged only after a scoped CSharpier format so the committed text is formatter-stable) and P3-T35 (feature folder). Documentation-only commits use the exempt form `git commit -m "" -- ` with every path under docs/features/active/ or docs/features/potential/. No `-m` value contains an angle bracket, a dollar sign or a backtick. No code file is edited after the P2-T8 commit. A PreToolUse refusal of any `git add`, `git commit`, `git merge`, `.cs` edit or `.csproj` edit is reported verbatim as `PRE-IMPLEMENTATION GATE BLOCKED` and stops the run; the executor does not modify hooks, checkpoints or permission configuration. An attribution trailer, when the session requires one, is a second -m paragraph with the address written bare (no angle brackets), for example -m "Co-Authored-By: Claude Opus 5.5 noreply@anthropic.com"; no other trailer form is used. +- **D-11 Git gates are pathspec-scoped and anchored.** Every `git diff` carries ANCHOR-SHA (or PREP-SHA) as ref operand or `--cached`; every name-listing diff is paired with a porcelain span in the same task; no gate asserts an empty unscoped porcelain. Porcelain gates after a commit admit this plan file (its check-off mark is written after each commit) and assert scope (no entry under TaskMaster/ or TaskMaster.Test/), never membership or count. +- **D-12 Spec amendments made by the planner in this pass.** AC14 now names the DIRECT coverage route as the admitted alternative when the Phase 0 stall probe reproduces the known local stall (the caller's constraint 5 admits it; the unamended text required the runner exactly, which a reproduced stall would have made unsatisfiable). AC15's repository-summary clause now states the D-9 comparability rule (the unamended "without falling below its baseline value" would have been decided by merge noise rather than by the change). The Test Strategy toolchain step 4 sentence was amended to match AC14. The spec header advanced to version 1.1. Revision round 1 amended AC14 and the Test Strategy step 4 sentence again: the DIRECT route is now described as the inner collector invocation with those four test classes excluded and the vstest hang-blame switch appended, post-processed by the runner's own helpers, because `CMD-COVERAGE-DIRECT` appends the blame switch the runner does not pass and the unamended wording described the route incompletely; the AC14 words "Phase 0 stall probe" became "baseline stall probe" so the criterion line carries no digit other than its label. The spec header advanced to version 1.2. No other criterion text changed. +- **D-13 Fixed artifact names.** No artifact name carries a timestamp; acceptance conditions name files exactly. The write time is the `Timestamp:` field (ISO yyyy-MM-ddTHH-mm). +- **D-14 Check-offs follow the loop.** Every acceptance criterion's evidence is either a Phase 0 observation, a post-format observation or a final-run observation, so every check-off task sits in Phase 3 after the loop and reads the artifact section that survived the final pass. Each check-off task flips exactly one checkbox and completes with the box unchecked when its evidence does not hold, recording `ACn: NOT MET` for P3-T33. Each of P3-T15 through P3-T32 appends exactly one line, ACn: MET or ACn: NOT MET followed by its failing values, to docs/features/active/2026-09-30-engine-toggle-prime-marker-registration-races-removal-944/evidence/other/ac-status-summary.md; P3-T15 creates that file with a Timestamp: line, and P3-T33 completes the same file. + +## Delivered source (the executor writes these texts; CSharpier output wins on any layout difference, and P2-T8 re-runs every token gate on the formatted text) + +Indentation rule: the production-file blocks are shown at their in-file indentation (eight, twelve, sixteen, twenty or twenty-four leading spaces) and are written exactly as shown. The new-partial block is shown with four leading spaces of Markdown indent on every line; those four spaces are removed on every line when the file is written, so `using` and `namespace` sit at column 0. Every line of every block is at most 100 columns at its in-file indentation, and every gated token sits whole on one physical line. + +**Production file `TaskMaster/Ribbon/EngineToggleStateCoordinator.cs`, edit E1 — `_primeGate` summary.** Replace the two text lines of the summary above `private readonly object _primeGate = new object();` (the line carrying `Serializes the at-most-one-prime decision.` and the line after it, which ends `task start; no await occurs inside it.`) with: + + /// Serializes the at-most-one-prime decision.

Every artifact records repository-relative paths only. No artifact, and no line of this plan, carries an absolute host path, an account name or a machine name. +- **Anchor substitution.** ANCHOR-SHA and PREP-SHA are substituted as D-6 states. +- **Payload channel.** Each indented payload block below is executed as one PowerShell 7 invocation (`pwsh -NoProfile -Command` with the payload in single quotes, or the session's PowerShell tool), with the worktree as the current directory set by the payload's own `Set-Location`. Payloads use double quotes only, and no gated token contains an apostrophe, so the outer single quotes never conflict. The `Command:` field of the artifact records the canonical command the payload runs (named in each payload's note), not the payload text. +- **Encoding.** Every payload that reads git output containing source text first sets `[Console]::OutputEncoding` to UTF-8, so non-ASCII characters in a blob (the em dashes in the coordinator's documentation) decode identically to the working file read with `-Encoding UTF8`. No gated token contains a non-ASCII character. +- **Exit codes.** `EXIT_CODE:` records the printed exit value of the payload's principal command. Deliberately failing runs carry `ExpectedExitCode:` equal to the observed non-zero value. A task that runs several commands names one as the row and records the others as named `Output Summary:` lines. +- **Tool resolution.** MSBuild and vstest.console.exe are resolved through vswhere inside each payload (`TOOLS` prelude below); the resolved paths are used, never printed into an artifact. +- **TOOLS prelude** (the first lines of every build and test payload after the `Set-Location`): + + $vswhere = Join-Path ${env:ProgramFiles(x86)} "Microsoft Visual Studio\Installer\vswhere.exe" + $msbuild = & $vswhere -latest -products * -find "MSBuild\**\Bin\MSBuild.exe" | Select-Object -First 1 + $vstest = & $vswhere -latest -products * -find "Common7\IDE\Extensions\TestPlatform\vstest.console.exe" | Select-Object -First 1 + New-Item -ItemType Directory -Path "coverage\logs" -Force | Out-Null + +- **Stall handling.** Every direct vstest run carries the hang-dump blame switch (CollectHangDump, TestTimeout 4min, HangDumpType None, spelled out in the CMD-VSTEST payload), so a stalled test is named in a Sequence document under the results directory; a run that produces one is recorded as failed with that test name. The RUNNER coverage route passes no blame argument, so P0-T17 and P3-T8 bound it by wall clock: a run still in progress after 120 minutes is `COVERAGE RUN STALLED`: stop and report. +- **Long-running payloads.** `CMD-COVERAGE-RUNNER`, `CMD-COVERAGE-DIRECT` and any payload expected to exceed 8 minutes are started as background processes with the payload's own standard output redirected to `coverage\logs\.result.log`; completion is detected by polling that file for the payload's final line, `PAYLOAD-COMPLETE`. If a foreground attempt times out anyway, the executor runs `pwsh -NoProfile -Command '"STRAY_TEST_PROCESSES: " + @(Get-Process -ErrorAction SilentlyContinue | Where-Object { $_.ProcessName -like "vstest*" -or $_.ProcessName -like "testhost*" -or $_.ProcessName -like "dotnet-coverage*" }).Count'` and reruns only when it prints `STRAY_TEST_PROCESSES: 0`; it never runs two collections at once. +- **Restart rule (Phase 3).** No code file is edited after the P2-T8 commit. If any of P3-T1 through P3-T8 fails or rewrites a file, the run stops and reports the failing step with its artifact; there is no in-plan repair. The only admitted repeat is the single pass-2 restart that P3-T8's re-run rule defines for the issue 780 sporadic failure, after which P3-T9 records both passes. When pass 2 ran, every later reader of a Phase 3 artifact (P3-T9, P3-T10, P3-T11 and the check-off tasks P3-T15 through P3-T32) reads that artifact's `PASS-2:` section in place of the pass-1 values, and a citation of a `POST-FORMAT:` or `FINAL-FIXTURE-RUN:` section means the `PASS-2:` copy of that section; when pass 2 did not run, the pass-1 sections are read. +- **Git working directory.** Every git command this plan writes without -C is run as git -C WORKTREE followed by the same arguments; the Command: field records it without -C. The WORKTREE operand of -C is written with forward slashes and without quotes, or wrapped in single quotes; it is never a double-quoted path that contains a backslash, because the pre-implementation gate's exemption check treats a backslash inside a double-quoted span as unresolvable and withholds the documentation-commit exemption D-10 relies on. No other character of an exempt git add or git commit line may be a dollar sign, a backtick or an angle bracket.

If the re-run format command again splits the repaired token, the repair is not re-attempted: record FORMATTER SPLITS GATED TOKEN with the token and the formatter's layout, and stop for re-planning before any git add. + - Command, commit: `git add -- TaskMaster/Ribbon/EngineToggleStateCoordinator.cs TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.PrimeRegistration.cs TaskMaster.Test/TaskMaster.Test.csproj docs/features/active/2026-09-30-engine-toggle-prime-marker-registration-races-removal-944` then `git commit -m "fix(ribbon): register the prime marker before the prime starts (issue 944)"` then `git show --name-only --format= HEAD` then `git status --porcelain -- TaskMaster TaskMaster.Test`. + - Acceptance: `CSHARPIER_EXIT_CODE: 0`; `PRECOMMIT-FORMAT-REWRITES:` is recorded (0 is expected when the Delivered Source layout is already formatter-stable; a non-zero value is admissible only with a passing `PRECOMMIT-FORMAT-RECHECK:`); the commit exits 0; `IMPLEMENTATION-COMMIT-SHA:` records `git rev-parse HEAD` as an observation; the `git show` name list contains exactly the three code paths plus paths under the feature folder and nothing else; the porcelain span scoped to the two code trees prints no line. From this commit on, no code file is edited. This commit stages paths outside every exempt tree, so it runs only in a session whose pre-implementation checkpoint is ready; a hook refusal is `PRE-IMPLEMENTATION GATE BLOCKED`. Before the git add, run the P3-T13 command unchanged and record its counts as PRE-COMMIT-HYGIENE: in this task's artifact; ACCOUNT_HITS=0, MACHINE_HITS=0 and DRIVE_USERS_HITS=0 are required (the FILES_SCANNED floor does not apply here); a non-zero count is repaired by replacing the occurrence with REDACTED-PATH and re-running the command before staging. + +### Phase 3 — Final QA Toolchain Loop, Coverage Delta, Footprint and Acceptance + +The loop is format, then the read-only format check, then the analyzer rebuild, then the nullable rebuild, then the coverage-enabled test run, in the CLAUDE.md order. The code was committed at P2-T8 after a scoped format, so no step of this loop may rewrite a code file and no code file is edited after P2-T8: a failing or rewriting step is stop and report (Execution conventions, restart rule), except the single pass-2 restart that P3-T8's re-run rule admits. P3-T9 records that a single pass completed clean. + +- [ ] [P3-T1] Run the formatter repository-wide with `dotnet tool run csharpier format .` and record FEATURE/evidence/qa-gates/csharpier-format.md with a before-and-after observation. + - Command: `CMD-HASH` before; `git status --porcelain -- . ":(exclude)docs/features" ":(exclude).claude"` before; `pwsh -NoProfile -Command 'Set-Location -LiteralPath "WORKTREE"; dotnet tool run csharpier format .; "CSHARPIER_EXIT_CODE: $LASTEXITCODE"'`; `CMD-HASH` after; the same scoped porcelain span after. + - Acceptance: `CSHARPIER_EXIT_CODE: 0` recorded as `EXIT_CODE:`; the artifact records four hashes (two before, two after) and defines the rewritten-file count as the number of the two Write Set source paths whose two hashes differ; it records both scoped porcelain outputs verbatim and requires them to be identical line sets (a difference is `FORMAT WIDENED FOOTPRINT`: stop and report, because P0-T13 established a clean drift baseline). The console line `Formatted N files` is not used as the rewritten count: CSharpier reports files processed, not files changed. The rewritten count must be 0; a non-zero count is `POST-COMMIT CODE REWRITE`: stop and report. +- [ ] [P3-T2] Re-run the scope and token gates on the formatted files `TaskMaster/Ribbon/EngineToggleStateCoordinator.cs` and `TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.PrimeRegistration.cs`: repeat P1-T1's `CMD-TOKEN-COUNT` with `TOKENS-PARTIAL`, and the P2-T6 and P2-T7 commands, appending `POST-FORMAT:` sections to FEATURE/evidence/regression-testing/prime-registration-partial-tokens.md, FEATURE/evidence/qa-gates/production-edit-scope.md and FEATURE/evidence/qa-gates/protected-regions-unchanged.md. + - Acceptance: every clause of P1-T1, P2-T6 and P2-T7 holds on the post-format tree, with every count, `FIRST-LINE`, `SPAN` and `REGION` row re-printed. A failing clause is `POST-COMMIT CODE REWRITE`: stop and report; no code edit is made after P2-T8. The `POST-FORMAT:` sections are the sections the Phase 3 check-off tasks cite. +- [ ] [P3-T3] Audit the post-format line counts of the coordinator source files with `CMD-LINECOUNT`, including `TaskMaster/Ribbon/EngineToggleStateCoordinator.cs` and `TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.PrimeRegistration.cs`, and record FEATURE/evidence/qa-gates/file-line-counts.md. + - Acceptance: `LINES` for the production file and the PrimeRegistration partial are each at most 500 (expected roughly 442 and 175); the production count is greater than `ANCHOR-LINES-PROD:` from P0-T8 (the edit landed); the main fixture, Race and PrimeFaultOrdering counts equal their `ANCHOR-LINES-*:` values. This is the authoritative AC18 size audit. +- [ ] [P3-T4] Verify formatting repository-wide, read-only, with `dotnet tool run csharpier check .` and record FEATURE/evidence/qa-gates/csharpier-check-final.md. + - Command: `pwsh -NoProfile -Command 'Set-Location -LiteralPath "WORKTREE"; dotnet tool run csharpier check .; "CSHARPIER_EXIT_CODE: $LASTEXITCODE"'` + - Acceptance: `CSHARPIER_EXIT_CODE: 0` recorded as `EXIT_CODE:` and the output reports no unformatted file. A non-zero exit is a failing step: stop and report. +- [ ] [P3-T5] Run the analyzer gate with `CMD-REBUILD` (`GATEARGS` analyzers, `TASKID` p3-t5) and record FEATURE/evidence/qa-gates/msbuild-analyzer-final.md (`Command:` records `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:EnableNETAnalyzers=true /p:EnforceCodeStyleInBuild=true`). + - Acceptance, all required: `EXIT_CODE: 0`; `ERRORS: 0`; `SKIP_CORECOMPILE_LINES: 0`; `CSC_OUT_TASKMASTER:` and `CSC_OUT_TASKMASTER_TEST:` each at least 1; `WRITESET_DIAGNOSTIC_LINES: 0`; `WARNINGS:` at most `ANALYZER-BASELINE-WARNINGS:` from P0-T14. +- [ ] [P3-T6] Run the nullable type-check gate with `CMD-REBUILD` (`GATEARGS` nullable, `TASKID` p3-t6) and record FEATURE/evidence/qa-gates/msbuild-nullable-final.md (`Command:` records `msbuild TaskMaster.sln /t:Rebuild /m /p:Configuration=Debug "/p:Platform=Any CPU" /p:TreatWarningsAsErrors=true`; no Nullable property override). + - Acceptance, all required: `EXIT_CODE: 0`; `ERRORS: 0`; `SKIP_CORECOMPILE_LINES: 0`; both `CSC_OUT_` counts at least 1; `WRITESET_DIAGNOSTIC_LINES: 0`; `WARNINGS:` at most `NULLABLE-BASELINE-WARNINGS:` from P0-T15; `TEST_DLL_EXISTS: True`. +- [ ] [P3-T7] Re-run the coordinator fixture on the rebuilt assembly TaskMaster.Test\bin\Debug\TaskMaster.Test.dll with `CMD-VSTEST` (`ASSEMBLY-TM`, `FILTER-COORD`, `TASKID` p3-t7, `NAMES-944`) and append a `FINAL-FIXTURE-RUN:` section to FEATURE/evidence/regression-testing/prime-registration-pass-after.md. + - Acceptance: `EXIT_CODE: 0`; `SEQUENCE_FILES: 0`; `COUNTERS` `failed` 0 and total equal to `BASELINE-TOTAL:` plus 3; all seven `NAMES-944` names `Passed`. This confirms the fixture on the exact assembly the coverage run measures. +- [ ] [P3-T8] Run the coverage-enabled test gate by the route P0-T16 fixed and record FEATURE/evidence/qa-gates/coverage-summary.md (fixed name per the spec): under `RUNNER` run `CMD-COVERAGE-RUNNER` with `STAGE` final, under `DIRECT` run `CMD-COVERAGE-DIRECT` with `STAGE` final, then `CMD-COVERAGE-POST` with `STAGE` final and `RAW` per the rule, with the same artifact fields as P0-T18 (the `ANCHOR-SHA:` row included). + - Re-run rule: when the first attempt's `FAILED-SET:` is exactly the single name `TryAddValuesAsync_UpdatesExistingValue` (the issue 780 sporadic failure P0-T18 admits), the loop restarts once at P3-T1 and P3-T1 through P3-T8 are repeated in order as pass 2, each appending a PASS-2: section to its own artifact; the first attempt is recorded as FIRST-ATTEMPT-FAILED-SET: and pass 2's values are the run; no other failure and no second re-run is admitted. When pass 2 runs, the top-level `Timestamp:`, `Command:`, `EXIT_CODE:` and `Output Summary:` fields of FEATURE/evidence/qa-gates/coverage-summary.md are rewritten with pass 2's values after pass 2's P3-T8 completes, the first attempt's exit code is kept as `FIRST-ATTEMPT-EXIT-CODE:` beside `FIRST-ATTEMPT-FAILED-SET:`, and no `ExpectedExitCode:` is added, so the first `EXIT_CODE:` an evidence reader encounters is the clean run's. No other artifact pass 2 appends to needs the same rewrite: pass 2 runs only when P3-T1 through P3-T7 each exited 0 on pass 1 (any other outcome stops the run first), so the first `EXIT_CODE:` of each of their artifacts, and of the four artifacts P3-T2 and P3-T7 append sections to (whose top-level fields were written by the passing P1-T1, P2-T6, P2-T7 and P2-T4 runs), already records a clean run. + - Acceptance, all required: branch (a) of P0-T18's branch rule (exit 0, both floors met, `FAILED-SET:` empty) on the recorded attempt; `SEQUENCE_FILES: 0` (DIRECT) and `TRX_PRESENT: True`; the `Output Summary:` holds at most 20 lines, as P0-T18 requires; the summary block in the `Details:` section reports `failed 0`; `COORD-CLASS-NODES: 1` in the `Details:` section; the three `METHOD` rows are present in the `Output Summary:`; the projection block in the `Details:` section contains the `TaskMaster` package with both counters. `RESULT`-level proof that the new tests executed is taken from P3-T7, because the runner's summary carries counts and failed names only. Any other outcome is a failing step: stop and report (a stall is `COVERAGE RUN STALLED` or `ABORTED`: stop and report). Under `RUNNER` the runner's own 80 percent line and 75 percent branch assertions are the floor gate; under `DIRECT` the `LINE-FLOOR:` and `BRANCH-FLOOR:` lines are. +- [ ] [P3-T9] Record the loop closure in FEATURE/evidence/qa-gates/toolchain-final-pass.md (fixed name per the spec). + - Acceptance: the artifact lists P3-T1 through P3-T8 with each step's `Command:` and exit code, states the pass number, states for P3-T1 that the rewritten count was 0 and the scoped porcelain sets were identical, states for P3-T4 that the check reported no differences, states for P3-T5 and P3-T6 that `SKIP_CORECOMPILE_LINES: 0` and both `CSC_OUT_` counts are at least 1, and states for P3-T8 the `COVERAGE-ROUTE:`, the `STALL-PROBE:` value from P0-T16 that selected it, and that the run exited 0. The pass number is 1, or 2 when P3-T8's re-run rule restarted the loop; in that case pass 1 is recorded with its single admitted failure and pass 2 is recorded as the clean pass. +- [ ] [P3-T10] Compute the coverage comparison for `TaskMaster/Ribbon/EngineToggleStateCoordinator.cs` from FEATURE/evidence/baseline/coverage-baseline.md and FEATURE/evidence/qa-gates/coverage-summary.md, run `CMD-CHANGED-LINES`, and append a `COMPARISON:` section to FEATURE/evidence/qa-gates/coverage-summary.md. + - Sources: the `METHOD` rows, the `First-party coverage:` lines and the `ROOT` lines are read from each artifact's `Output Summary:`; the `COORD-LINES`, `COORD-BRANCHES` and `METHOD-LINE` rows are read from each artifact's `Details:` section (the bounded summary P0-T18 defines leaves them there). + - Rows, all required: `COORD-LINES-BASELINE:` and `COORD-LINES-FINAL:` (covered over valid); `COORD-UNCOVERED-BASELINE:` and `COORD-UNCOVERED-FINAL:` (valid minus covered); `COORD-BRANCHES-BASELINE:` and `COORD-BRANCHES-FINAL:`; for each of `StartPrimeIfNeeded`, `StartObservedPrime` and `CompletePrime`, `METHOD-BASELINE:` and `METHOD-FINAL:` (the two `METHOD` rows verbatim); the `CMD-CHANGED-LINES` output verbatim; `FIRST-PARTY-BASELINE:` and `FIRST-PARTY-FINAL:` (the two `First-party coverage:` lines verbatim, which are the repository summary line); `ROOT-BASELINE:` and `ROOT-FINAL:`; `DENOMINATOR-BRANCH:` either `COMPARABLE` (the two root lines-valid figures differ by at most 1 percent of the baseline figure; then the final root line-rate must be at least the baseline root line-rate minus 0.005) or `INCOMPARABLE` (recorded, not gated, with the one-sentence reason from D-9). + - Acceptance, all required: `METHOD StartPrimeIfNeeded` final `rate=` at least 90.00; `METHOD StartObservedPrime` final `rate=` at least 90.00 and final `elements=` strictly greater than baseline `elements=` (the continuation's block body replaces a single-expression lambda, so the measured statement set must grow; a document that dropped the closure lines would report fewer elements than the baseline, whose span includes the old lambda line, and fails this clause); `METHOD CompletePrime` final `elements=` equals its baseline and final `uncovered=` is at most its baseline; `CHANGED-LINES-UNCOVERED: 0` and `CHANGED-LINES-WITH-ELEMENT:` at least 4 (every changed executable line is covered); `COORD-LINES-FINAL` covered at least `COORD-LINES-BASELINE` covered; `COORD-UNCOVERED-FINAL` at most `COORD-UNCOVERED-BASELINE`; `COORD-BRANCHES-FINAL` covered at least baseline covered; exactly one `DENOMINATOR-BRANCH:` value is recorded and, under `COMPARABLE`, its rate clause holds. The method figures are computed as D-8 states, so a third party re-running `CMD-COVERAGE-POST` on the two retained documents obtains the same numbers. +- [ ] [P3-T11] Verify the determinism-token constraints of AC13 over the anchored diff of TaskMaster.Test/Ribbon and record FEATURE/evidence/qa-gates/determinism-tokens.md. + - Command: `pwsh -NoProfile -Command 'Set-Location -LiteralPath "WORKTREE"; $added = @(git diff -U0 ANCHOR-SHA -- TaskMaster.Test/Ribbon | Where-Object { $_.StartsWith("+") -and -not $_.StartsWith("+++") }); "ADDED-LINE-COUNT: $($added.Count)"; "ADDED-FILES: $(@(git diff --name-only ANCHOR-SHA -- TaskMaster.Test/Ribbon) -join ", ")"; foreach ($t in @("Thread.Sleep", "Task.Delay", "SpinWait", "while (", "for (", "Retry", "DoNotParallelize", "Parallelize", "[Timeout", "Timeout=", "DateTime", "Stopwatch", "Environment.TickCount", ".Wait(", ".Result", "GetResult(", "ManualResetEvent", "SemaphoreSlim", "GetTempFileName", "GetTempPath", "File.", "TaskScheduler", "TimeProvider")) { "ADDED-TOKEN [$t] = $(@($added | Where-Object { $_.Contains($t) }).Count)" }'` together with `git status --porcelain -- TaskMaster.Test/Ribbon`. + - Acceptance: `ADDED-LINE-COUNT:` at least 150 (the new partial; a smaller figure means the diff missed the new file); `ADDED-FILES:` is exactly `TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.PrimeRegistration.cs` (no other file of the directory changed); every `ADDED-TOKEN` count is 0; the porcelain span prints no line (the directory has no uncommitted change, so the anchored diff is the committed content). The token list is applied to added lines of the test directory only, so this plan's own prose cannot trip it.

The phrase "The returned continuation task always completes successfully" is wrapped across 287 and 288 at PREP-SHA, so a line-oriented absence count of the whole phrase reads 0 before the fix and could never fail. The plan gates the single-line token `The returned continuation task always` (1 before, 0 after) and the joined-text count of `CMD-PHRASE-COUNT` (1 at P0-T6, 0 at P2-T6). +2. `git show` output is decoded through the console encoding, and the coordinator's documentation carries em dashes, so every region comparison sets UTF-8 output decoding and strips a byte-order mark and trailing carriage returns on both sides; without that, a byte-identical region could compare unequal. +3. The `GetPrimeTask` region and the `CompletePrime` region both change between PREP-SHA and the anchor (by #942), so P0-T7 uses them as the positive control that the region comparison detects change, while the two edit windows must compare equal across that same merge. +4. A per-method rate over the new `StartObservedPrime` is computed over a span that contains the lambda body; P3-T10 requires the final element count to exceed the baseline strictly so that a document in which the closure lines were dropped cannot satisfy the ninety-percent clause over the old statement set. +5. The unamended AC15 required the repository summary line not to fall at all, which the merged denominator's run-to-run variation decides independently of this change; the unamended AC14 required the runner exactly, which the documented local stall can make unsatisfiable. Both were amended in the spec by the planner (D-12) rather than reinterpreted inside the plan. + +Revision round 1 pass, 2026-09-30, same worktree. Every citation the twelve deltas touched was re-derived in this pass against the current files, and its sibling region re-read: + +- `docs/features/active/2026-09-30-engine-toggle-prime-marker-registration-races-removal-944/spec.md` — header line 6 (Last Updated) and line 8 (Version 1.2) re-read after the edit; the Test Strategy step 4 sentence at 245 re-read with the hang-blame words; AC14 at 266 re-read as one physical line, and a search for any acceptance line carrying a digit, an angle bracket or a percent sign after its label found none (the AC14 words "Phase 0" were the only prior instance). Sibling region: AC1 to AC13 and AC15 to AC18 at 253 to 270 are unchanged and each still sits on one line, so no check-off prefix moved. +- `scripts/vscode/Invoke-MSTestWithCoverage.ps1` — line 91 hard-codes `/TestCaseFilter:TestCategory!=LiveOutlook` and the file contains no blame argument, which is the fact the amended AC14, D-7 and D-12 wording rests on; line 97 still defines `ConvertTo-DerivedCoverageSettingsXml`. +- `docs/features/potential/promoted/2026-09-30-engine-toggle-prime-marker-registration-races-removal.md` — `Status: Promoted` at line 5 and `Issue: #944` at line 9 re-read (fact 7 and P0-T4). +- This plan's Delivered Source — the new-partial block spans plan lines 238 to 412, 175 lines, which is the corrected P3-T3 expectation; the production edit adds 22 lines to the anchored file (E1 0, E2 1, E3 21: 68 replacement lines for the 47 PREP-SHA lines 257 to 303), so 442 is unchanged; the edited E3 remarks line at plan line 205 is 95 columns at its in-file indentation, and no `TOKENS-PROD` token, no quoted prose token and no count list contains the word that changed. +- This plan's P0-T4, P0-T5, P0-T18, P0-T20, P1-T2, P2-T8, P3-T3, P3-T8 to P3-T10 and P3-T15 to P3-T35 texts, D-7, D-10, D-12, D-14 and the Execution conventions — re-read after the edits. Sibling checks: P0-T4's commit condition keys on the cached listing, which lists the record under every non-`TRACKED-UNCHANGED` state; P0-T5's overlap intersection excludes the feature folder, because the plan file is both in the HEAD-to-origin/main diff and dirty after P0-T4's check-off, and without the carve-out the stop would fire on every correct run; the P1-T2 payload still uses single outer quotes and double inner quotes only; P3-T10 now names which figures it reads from `Output Summary:` and which from `Details:`; P3-T13's `FILES_SCANNED` floor of 42 is unaffected because P3-T15 creates the status summary after P3-T13; the Write Set lists `ac-status-summary.md` once. + +Revision round 1 findings beyond the literal delta text, applied and stated here so the executor-preflight sees them: + +6. D2's `git diff --name-only HEAD origin/main` lists the feature folder, which P0-T4 commits and origin/main lacks, while P0-T4's own check-off leaves the plan file dirty; the intersection therefore excludes feature-folder paths. The upstream-overlap stop still covers .claude/agent-memory/ and every other tree. +7. D1's `STAGED-NEW` state also admits an `AM` line (staged new, then edited), which the same commit resolves. +8. D5's pre-commit sweep was extended to P3-T35, recording into evidence-hygiene.md, because the spec check-offs and the P3-T15 to P3-T34 artifacts are written after P3-T13 and would otherwise be committed unscanned. +9. D6's pass-2 restart needs a reader rule, so the Execution conventions state that every later reader cites the `PASS-2:` copy of a section when pass 2 ran. +10. D12's -C rule is satisfied inside payloads by the payload's own `Set-Location`, which the convention now states so the executor does not rewrite payload text. + +Revision round 2 pass, 2026-09-30, same worktree (HEAD at PREP-SHA). Every citation the three deltas touched was re-derived in this pass against the current files, and its sibling region re-read: + +- `TaskMaster/Ribbon/EngineToggleStateCoordinator.cs` — `private readonly ConcurrentDictionary _primeTasks = new ConcurrentDictionary<` occurs once (line 77) and `>(StringComparer.Ordinal);` once (line 80), so `PRIMETASKS-DECLARATION` resolves to lines 77 to 80 (start offset 0 on the declaration line, end offset 0 on the closing line, the same field-line convention `PRESSED-STATE` uses for 62 to 70). Neither token occurs in the E1, E2 or E3 replacement text, and fact 2 places #942's edits after the `GetPrimeTask` `returns` element, so the region is untouched by both. Sibling region: 58 and 61 (the `_primeGate` summary tag lines), 71 (blank), 72 and 76 (the `_primeTasks` summary tag lines), 73 to 75 (E2 text lines), 257 to 303 (the E3 block) and 304 (the blank line before the `ApplyPrimeAsync` summary at 305) are the only lines outside every `PROTECTED` region: `HEAD` ends at 57, `PRESSED-STATE` is 62 to 70, `MIDDLE` starts at 81 and ends at 236, `GETPRIMETASK` is 237 to 256, `APPLYPRIME-AND-COMPLETEPRIME` starts at 305. The supplied R2(b) text omitted line 304, so the paragraph was minimally corrected to name the blank line after the block; the `PRIME-START` window (257 to 304) contains it. +- This plan's region-set heading and P2-T7 title — both claimed that the protected set covers every line outside the three edits, and the heading claimed a partition although `GATE-AND-TASKS-FIELDS` (58 to 80) already contained `PRESSED-STATE`; both were reworded to the verified coverage. The authoring-pass record above ("partition the file") describes the state before this correction and is retained as history. +- Readers of the region rows: P0-T7 records `PROTECTED` rows without a gate except `GETPRIMETASK` and `APPLYPRIME-AND-COMPLETEPRIME`, so the new row (expected `equal=True` across the #942 merge) needs no P0-T7 change; P2-T7's row list now names it; P3-T2 re-prints every `REGION` row, so it carries the new row with no text change; P3-T22 reads only `APPLYPRIME-AND-COMPLETEPRIME` and `PROTECTED_FILES_DIFF_EXIT`, and P3-T23 and P3-T25 read only

The continuation task is the value stored in `_primeTasks` and is the handle returned by `GetPrimeTask`. +- `ApplyPrimeAsync` is an `async` method with no `catch`: `NextSequence()`, then `await engines.EngineActiveAsync(engineName).ConfigureAwait(false)`, then `TryApplyState` and conditional `_invalidateControl`. Its synchronous prefix (including the call into `EngineActiveAsync`) runs on the thread that called `GetPressed`, while `_primeGate` is held. +- `CompletePrime` (pre-#942): returns on `RanToCompletion`; otherwise `_primeTasks.TryRemove(engineName, out _)` (no lock), then `_logError(...)`. Post-#942 `[B]` the order becomes log-then-`TryRemove`. +- `GetPrimeTask` returns the stored task or `Task.CompletedTask`. `_primeTasks` is written only by `StartPrimeIfNeeded` and removed only by `CompletePrime`. A successful prime's marker stays registered for the session (success never removes) `[V]`. +- The only production caller is `RibbonController.EngineCommands.cs` (`EngineToggles` lazily constructs the coordinator; `IsEngineToggleActive` → `GetPressed`; the `logError` sink is `logger.Error(message, exception)`). Production never calls `GetPrimeTask` `[V]` (grep of `GetPrimeTask|_primeTasks|StartObservedPrime|CompletePrime` finds only the production file and the two fixture partials). + +### 1.2 Why an already-failed task is a realistic input `[V]` + +- `AppItemEngines.EngineActiveAsync` is `async` and begins with `await Globals.AF.Manager.Configuration`. +- `ManagerAsyncLazy.Configuration` is an `AsyncLazy>`. `AsyncLazy` wraps a `Lazy>`, so a faulted configuration load is cached and every later `await` rethrows synchronously. `EngineActiveAsync` therefore returns an already-faulted task, `ApplyPrimeAsync` returns an already-faulted task, and the hazard window is at its widest. (`ResetConfigAsyncLazy()` exists and replaces the lazy; it is the only recovery path.) + +### 1.3 Tests `[V]` + +- `TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.cs`: 459 lines (460 with trailing newline), `public partial class`, holds the private `Harness` (strict `Mock`, recording `Invalidations`, `Notifications`, `Errors`, optional `OnInvalidate`) and `LoggedError`. #942 `[B]` adds `OnLogError` (~+8 lines). +- `TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.Race.cs`: 277 lines; #735 last-writer and CR-2 canceled-prime tests. +- `TaskMaster.Test/TaskMaster.Test.csproj` uses explicit `` items: `Ribbon\EngineToggleStateCoordinatorTests.cs` and `Ribbon\EngineToggleStateCoordinatorTests.Race.cs`. #942 `[B]` adds `Ribbon\EngineToggleStateCoordinatorTests.PrimeFaultOrdering.cs`. +- Hazard B is already reachable from existing tests `[D]`: the re-prime at the end of `GetPressed_WhenPrimeFaults_LogsErrorAndStillReturnsFalse` and the second read in `GetPressed_WhenPrimeIsCanceled_LogsErrorAndClearsPrimeMarker` both re-enter an already-faulted/canceled `probe.Task`. Neither asserts anything the race can falsify (the second draws its conclusion from `NotBeSameAs(firstPrime)`, which holds whether `GetPrimeTask` returns the stale continuation or `Task.CompletedTask`). This matches NB-2 in `docs/features/active/2026-09-02-ribbon-engine-toggle-defects-735/code-review.2026-09-03T06-19.md` (lines 188-221), which recommended "take `_primeGate` around the `TryRemove`, or register a placeholder marker before attaching the continuation". + +## 2. Q1 — hazard mechanism on .NET Framework 4.8 TPL + +1. `[V]` All TaskMaster projects target `v4.8.1`. +2. `[V-web]` `StandardTaskContinuation.Run(completedTask, bCanInlineContinuationTask)` inlines **only** when `bCanInlineContinuationTask && (options & TaskContinuationOptions.ExecuteSynchronously) != 0`; otherwise it calls `continuationTask.ScheduleAndStart(needsProtection: true)`. +3. `[V-web]` `ThreadPoolTaskScheduler.QueueTask` for a non-`LongRunning` task calls `ThreadPool.UnsafeQueueCustomWorkItem(task, forceToGlobalQueue)`; it never executes the task on the queuing thread. +4. `[D]` (the `ContinueWithCore` body could not be retrieved; the fetched page was truncated) Whether the antecedent is already complete when `ContinueWith` is called or completes later, dispatch goes through `StandardTaskContinuation.Run`. With `TaskContinuationOptions.None`, item 2 means the continuation is **always queued** to the thread pool and **never runs inline on the registering thread**. The only other inlining route is `TryExecuteTaskInline` via a `Wait` on the continuation task, and nothing on the registering thread waits on it. +5. **Race window** `[D]`: from the instant the continuation is queued (inside `ContinueWith`) until the dictionary store `_primeTasks[engineName] = ...` completes on the registering thread. A pool thread that dequeues the continuation inside that window runs `CompletePrime`; its `TryRemove` finds no entry (first prime) or removes nothing relevant, and the registering thread then stores a continuation that has already finished or is finishing. `ContainsKey` is then true for the rest of the session. The window is not limited to synchronously-failed primes: any prime whose antecedent completes on another thread between `ContinueWith` registration and the store has the same exposure. A synchronously-failed prime simply opens the window at the earliest possible point. +6. **Consequence for fix design** `[D]`: because the continuation is never inline on the registering thread, Monitor re-entrancy does not currently defeat a lock-in-`CompletePrime` fix. It would if `ExecuteSynchronously` were ever added (item 2), which #942 already rejected for this reason `[B]`. + +## 3. Q2 — candidate fix shapes + +Evaluation criteria: correctness under every interleaving (including a hypothetical inline continuation), #942 compatibility (report-then-clear; handle captured before the trigger is the same instance seen inside the sink; that handle completes only after report and removal; `GetPrimeTask` afterwards is `Task.CompletedTask`), `GetPrimeTask` never-faults contract, at-most-one prime per engine, single-`catch` invariant, deadlock freedom, size, single production file. + +| Shape | Fixes hazard B | Inline-safe | #942 assertions | Deterministic RED test possible | Size | +|---|---|---|---|---|---| +| (i) `_primeGate` around `TryRemove` in `CompletePrime` | yes (cross-thread only) | **no** (Monitor re-entrant) | pass | **no** | ~4 lines | +| (ii) identity-conditional removal alone | **no** | n/a | pass | no | ~2 lines | +| (iii) register-before-start with a `TaskCompletionSource` marker | yes | yes | pass | **yes** | ~+12 lines | +| (iv-a) cold `Task` + `Unwrap` + `RunSynchronously` | yes | yes | pass | yes | ~+4 lines | + +### (i) Lock in `CompletePrime` + +Correct today: the removal blocks until the registering thread leaves `_primeGate`, which is after the store. `_logError` runs before the lock under #942's order, so no user code runs under the gate; deadlock-free. Rejected because (a) its correctness depends on the continuation never running on the registering thread — Monitor re-entrancy would let an inline continuation remove before the store — so it is a property of `TaskContinuationOptions.None` rather than of the type; (b) no program-order discriminator can tell it apart from the defect (the handle is still unregistered while `EngineActiveAsync` runs), so the bugfix workflow's "fails before the fix" test is impossible without a scheduler seam, which #942 already rejected `[B]`. + +### (ii) Identity-conditional removal alone + +`((ICollection>)_primeTasks).Remove(new KeyValuePair(engineName, handle))` is available on net48 (the public `TryRemove(KeyValuePair)` overload is .NET 5+). Alone it does not fix the defect: when removal precedes registration there is nothing to remove, and the later store still leaves a finished marker. It also needs the continuation to know its own handle, which with the current shape is only obtainable through a closure variable assigned after `ContinueWith` returns — the same race. Rejected as a fix; see §4.4 for its status as optional hardening. + +### (iii) Register-before-start — **recommended** + +Inside the existing `lock (_primeGate)`: after the `ContainsKey` check, create `var marker = new TaskCompletionSource(TaskCreationOptions.RunContinuationsAsynchronously);`, store `_primeTasks[engineName] = marker.Task;`, **then** call `StartObservedPrime(engines, engineName, controlId, marker)`. `StartObservedPrime` becomes `void`, discards the continuation task (`_ = ...` for MA0134), and the continuation body is `try { CompletePrime(completed, engineName); } finally { marker.SetResult(true); }`. `CompletePrime` is unchanged from its post-#942 form. + +- **Correctness, all interleavings** `[D]`: the marker is in the dictionary before `ApplyPrimeAsync` is invoked, so it is present before the prime can complete on any thread, including inline. `_primeTasks[engineName]` has exactly one writer (`StartPrimeIfNeeded`, gated by `ContainsKey` under `_primeGate`), so while the marker is registered no other value can replace it; the only removal is that marker's own `CompletePrime`. Therefore `TryRemove(engineName, out _)` in `CompletePrime` always removes this prime's own marker, and a finished failed prime can never leave a marker behind. +- **#942 compatibility** `[D]`: the handle captured before `probe.SetException` is `marker.Task`; inside the sink (before `TryRemove`) `GetPrimeTask` returns the same `marker.Task`; `SetResult` runs in `finally` after `CompletePrime` returns, i.e., after the report and after the removal, so `await prime` resumes only then, and `GetPrimeTask` afterwards returns `Task.CompletedTask`. The #942 `` guarantee ("the handle is incomplete while the marker is registered", scoped to the failure path) holds. On the success path the marker stays registered and completed, exactly as the continuation handle does today. +- **Never-faults contract** `[D]`: `marker.Task` is only ever completed with `SetResult`, so it cannot fault or cancel — stronger than today, where a throwing sink would fault the continuation handle. +- **At-most-one prime** `[D]`: unchanged; the check-and-register remains atomic under `_primeGate`, and registration now precedes start. +- **Single-`catch` invariant** `[V]`/`[D]`: `try`/`finally` adds no `catch`. +- **Deadlock** `[D]`: no new lock acquisition. `_primeGate` is still held across a dictionary probe, a store, and the synchronous prefix of the prime start — identical to today. `CompletePrime` takes no lock. +- **`RunContinuationsAsynchronously`** `[V]`/`[V-web]`: present in the .NET Framework reference `Task.cs` and already used in production TaskMaster (`TaskMaster/AppGlobals/NonBlockingDelay.cs:68`, `TaskMaster/AppGlobals/AppOlObjects.FolderTreeService.cs:52`). It is recommended so that awaiters of the handle (tests) resume on their own pool work item instead of running inside the coordinator's `finally`. It is not required for correctness. +- **Synchronous start preserved** `[D]`: `ApplyPrimeAsync` is still invoked directly on the calling thread, inside the lock, as today. +- **Scope**: one production file, net ≈ +12 lines including comment and doc updates. + +### (iv-a) Cold start — rejected + +`var start = new Task(() => ApplyPrimeAsync(...)); _primeTasks[engineName] = start.Unwrap().ContinueWith(...); start.RunSynchronously(TaskScheduler.Default);` also registers before start and keeps the continuation as the handle. Rejected: `RunSynchronously` falls back to queue-and-`Wait` when the inlining stack guard refuses, which would block the Outlook STA the class remarks forbid blocking; and the `Task`/`Unwrap` indirection is less readable than an explicit marker (Simplicity first). + +### Rejected alternatives (summary) + +- `await Task.Yield()` at the top of `ApplyPrimeAsync`: moves `EngineActiveAsync` off the calling thread and does not close the window for antecedents that complete on another thread. +- `TaskContinuationOptions.ExecuteSynchronously`: makes the defect deterministic (inline removal before the store) `[B]`. +- Scheduler constructor seam: rejected by #942 `[B]`; unnecessary because (iii) admits a program-order test. + +## 4. Recommended design + +### 4.1 State model + +`_primeTasks[engine]` holds a *marker* — `TaskCompletionSource.Task` — for the lifetime of an in-flight prime and, after success, for the session. Transitions: absent → registered-incomplete (under `_primeGate`, before start) → on success: registered-complete (permanent) | on failure: report → removed → complete. + +### 4.2 Production changes (one file: `TaskMaster/Ribbon/EngineToggleStateCoordinator.cs`) + +1. `StartPrimeIfNeeded`: create and register the marker before calling `StartObservedPrime`; add a *why* comment naming #944. +2. `StartObservedPrime`: signature gains `TaskCompletionSource marker`, returns `void`; continuation body `try { CompletePrime(completed, engineName); } finally { marker.SetResult(true); }`; keep `CancellationToken.None, TaskContinuationOptions.None, TaskScheduler.Default`. Rewrite its `` sentence "The returned continuation task always completes successfully, which is what makes it safe for a test to await." to describe the marker. +3. Doc updates: `_primeTasks` field summary ("The in-flight — or most recently completed — prime per engine key" → the registered marker, registered before the prime starts); `_primeGate` summary ("a dictionary probe and a task start" → probe, marker registration, and task start); `GetPrimeTask` summary/returns as rewritten by #942 remain true — verify wording after the #942 merge rather than re-edit it. +4. `CompletePrime`: no code change. + +Expected post-change size: ≈ 415 + #942 delta + ~12, well under 500 `[D]`. + +### 4.3 Invariants preserved + +report-then-clear ordering; #942 test assertions; all existing tests in both partials (§5.3); at most one concurrent prime per engine; exactly one `catch` in the type; no new lock, no deadlock path; `ApplyPrimeAsync` starts synchronously on the caller. + +### 4.4 Optional hardening (not recommended for this issue) + +Identity-conditional removal of `marker.Task` becomes race-free under (iii) because the marker exists before the continuation is created. It is not needed (§3 (iii) single-writer proof), no reachable interleaving distinguishes it, and it would edit the #942-owned `TryRemove` line. Keep `TryRemove(engineName, out _)`. + +## 5. Q3 — deterministic regression tests + +The raw race cannot be forced: `ContinueWith` is hard-wired to `TaskScheduler.Default` and nothing observable executes between the queueing inside `ContinueWith` and the dictionary store. The deterministic RED therefore targets the invariant whose absence *is* the defect — "the marker is registered before the prime can complete" — using program order only. + +### 5.1 Test 1 — program-order discriminator (deterministic RED) + +`GetPressed_WhenPrimeStarts_RegistersPrimeHandleBeforeActivationReadRuns` + +- Arrange: `harness.Engines.Setup(x => x.EngineActiveAsync(SpamEngine)).Returns(() => { handleSeenDuringRead = harness.Coordinator.GetPrimeTask(SpamEngine); handleCompletedDuringRead = handleSeenDuringRead.IsCompleted; return Task.FromException(failure); });` — this callback runs synchronously inside `ApplyPrimeAsync` on the test thread. Record only; assert outside the callback (an assertion thrown inside would become a prime fault). +- Act: `harness.Coordinator.GetPressed(SpamEngine);` +- Assert: `handleCompletedDuringRead.Should().BeFalse(...)`; then `await handleSeenDuringRead;`; `Errors` contains a single entry whose exception `BeSameAs(failure)`; `GetPrimeTask(SpamEngine)` `NotBeSameAs(handleSeenDuringRead)` and `IsCompleted` is true. +- Before the fix: inside the callback the dictionary has no entry, so `GetPrimeTask` returns `Task.CompletedTask` and `handleCompletedDuringRead` is `true`. The first assertion fails on every run, by program order alone (the store happens only after `StartObservedPrime` returns, which is after `EngineActiveAsync` was called). **Deterministic RED.** +- After the fix: the marker is registered and cannot be complete (its completion requires the continuation, which requires `ApplyPrimeAsync`'s task, which has not yet returned). Awaiting the marker resumes only after report and removal, so the remaining assertions are deterministic. **Deterministic GREEN.** +- Do not assert `GetPrimeTask(SpamEngine)` identity immediately after `GetPressed` returns: post-fix the queued continuation may already have removed the marker, so that assertion would be timing-dependent. +- Do not rely on `BeSameAs(Task.CompletedTask)` as the discriminator; `IsCompleted` is sufficient and independent of the lazily cached singleton. + +### 5.2 Tests 2 and 3 — behavioral re-prime guards (deterministic GREEN; RED not deterministic) + +`GetPressed_AfterPrimeFaultsSynchronously_LaterReadStartsNewPrime` and `GetPressed_AfterPrimeIsCanceledSynchronously_LaterReadStartsNewPrime` + +- Arrange: `SetupSequence(x => x.EngineActiveAsync(SpamEngine)).Returns(Task.FromException(failure)).Returns(Task.FromResult(true))` (canceled variant: `Task.FromCanceled(new CancellationToken(true))`, requires `using System.Threading;`). +- Act: `GetPressed`; `await GetPrimeTask(SpamEngine)`; second `GetPressed`; `var secondPrime = GetPrimeTask(SpamEngine); await secondPrime;`. +- Assert: `Engines.Verify(x => x.EngineActiveAsync(SpamEngine), Times.Exactly(2), ...)`; `GetPressed(SpamEngine)` is `true`; `Invalidations` equals `[SpamToggleControlId]`; `Errors` contains a single entry (faulted: `BeSameAs(failure)`; canceled: `BeAssignableTo`). +- Post-fix determinism `[D]`: the first `GetPrimeTask` returns either the marker (awaiting it resumes after removal) or `Task.CompletedTask` (which means removal has already happened); in both cases the second read starts a new prime.

The registering thread then stores a handle for a prime that has already finished. `_primeTasks.ContainsKey(engineName)` stays true for the rest of the session, and no later `GetPressed` read can start a new prime for that engine. This is hazard B from the issue #942 research, first recorded as NB-2 in the issue #735 code review, and not previously promoted. + +Environment: +- OS/version: Windows 11 / windows-latest +- Runtime: C#, .NET Framework v4.8.1 (all TaskMaster projects) +- Reachability: production path (`RibbonController` `getPressed` polling through `IsEngineToggleActive` to `GetPressed`); also reachable from the re-prime at the end of the existing test `GetPressed_WhenPrimeFaults_LogsErrorAndStillReturnsFalse` and the second read in `GetPressed_WhenPrimeIsCanceled_LogsErrorAndClearsPrimeMarker` +- Data source or fixture: n/a + +Impact / Severity: +- [ ] Blocker +- [ ] High +- [x] Medium +- [ ] Low + +## Repro & Evidence + +Steps to Reproduce: +1. Arrange for `EngineActiveAsync` to return an already-faulted task. In production this occurs after a cached configuration-load fault: `AppItemEngines.EngineActiveAsync` begins with `await Globals.AF.Manager.Configuration`, which is an `AsyncLazy` over a `Lazy` of a task, so a faulted load is cached and every later await rethrows synchronously. +2. Call `GetPressed` for that engine. On a cache miss it calls `StartPrimeIfNeeded`. +3. Inside `lock (_primeGate)`, the statement `_primeTasks[engineName] = StartObservedPrime(engines, engineName, controlId);` first evaluates `StartObservedPrime`, which calls `ContinueWith` on the already-faulted task. With `TaskContinuationOptions.None` the continuation is queued to the thread pool immediately. A pool thread can dequeue it and execute `_primeTasks.TryRemove(engineName, out _);` inside `CompletePrime` before the registering thread performs the dictionary store. + +Expected: +A finished failed or canceled prime never leaves a marker in `_primeTasks`, so a later `GetPressed` can start a new prime. + +Actual: +The removal can precede the registration.

That ordering is owned by issue #942. + - Identity-conditional removal (the `ICollection` of `KeyValuePair` `Remove` overload). Research section 4.4 shows it is unnecessary under the chosen design and it would edit the issue #942-owned `TryRemove` line. + - A scheduler constructor seam, `TaskContinuationOptions.ExecuteSynchronously`, `await Task.Yield()` in `ApplyPrimeAsync`, a cold `Task` with `RunSynchronously`, or a lock inside `CompletePrime` (rejected in research section 3). + - The throwing-`logError`-sink hazard and the log volume after a permanent configuration fault (recorded under Rollout and Follow-up; no issue is filed by this item). +- Explicitly excluded files (named in plain prose on purpose; these must be byte-identical to the re-anchored origin/main after this change): + - TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.cs (main fixture, including the private `Harness` and its issue #942 `OnLogError` hook) + - TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.Race.cs + - TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.PrimeFaultOrdering.cs (added by issue #942) + - TaskMaster/Ribbon/RibbonController.EngineCommands.cs (the only production caller; unaffected) + - TaskMaster/TaskMaster.csproj (the production compile item already exists) + +## Root Cause Analysis + +`StartPrimeIfNeeded` evaluates the right-hand side of `_primeTasks[engineName] = StartObservedPrime(engines, engineName, controlId);` before it performs the store. That evaluation calls `ApplyPrimeAsync` and attaches the continuation `completed => CompletePrime(completed, engineName),` with `TaskContinuationOptions.None,` and `TaskScheduler.Default`. On .NET Framework 4.8 the continuation is never run inline on the registering thread with those options; it is queued to the thread pool (research section 2, items 2 to 4, verified against the .NET Framework reference source). The race window therefore runs from the queueing inside `ContinueWith` to the completion of the dictionary store on the registering thread. + +`CompletePrime` removes the marker without taking `_primeGate`. A pool thread that runs `CompletePrime` inside the window finds no entry to remove (first prime) and returns; the registering thread then stores a handle for the finished prime. Because `_primeTasks` is written only by `StartPrimeIfNeeded` and removed only by `CompletePrime`, nothing removes that handle afterwards. + +The window is not limited to synchronously failed primes: any antecedent that completes on another thread between `ContinueWith` registration and the store has the same exposure. A synchronously failed prime opens the window at the earliest point. No current test fails on this, because the existing re-prime assertions hold whether `GetPrimeTask` returns the stale handle or `Task.CompletedTask` (research section 1.3). + +The defect is an ordering property: the marker is registered after the prime can complete. The fix restores the invariant "the marker is registered before the prime can complete, on any thread". + +## Proposed Fix + +### Design summary (what changes where): + +Adopt research design 3 (iii), register-before-start, in `TaskMaster/Ribbon/EngineToggleStateCoordinator.cs` only: + +1. In `StartPrimeIfNeeded`, inside the existing `lock (_primeGate)` block and after the `if (_primeTasks.ContainsKey(engineName))` check, create `var marker = new TaskCompletionSource(TaskCreationOptions.RunContinuationsAsynchronously);`, store `_primeTasks[engineName] = marker.Task;`, and only then call `StartObservedPrime(engines, engineName, controlId, marker);`. Add a short why-comment stating that registration precedes the start so that a prime completing on any thread, including before `StartObservedPrime` returns, always finds its own marker to remove (issue #944). +2. `StartObservedPrime` becomes `private void StartObservedPrime(IAppItemEngines engines, string engineName, string controlId, TaskCompletionSource marker)`. It discards the continuation task (`_ = ApplyPrimeAsync(...).ContinueWith(...)`, which satisfies MA0134) and the continuation body becomes `try { CompletePrime(completed, engineName); } finally { marker.SetResult(true); }`. The arguments `CancellationToken.None`, `TaskContinuationOptions.None` and `TaskScheduler.Default` are unchanged. +3. `CompletePrime` is not edited. + +State model (research section 4.1): `_primeTasks[engine]` is absent, then registered-incomplete (under `_primeGate`, before the start), then either registered-complete for the session (success) or, on failure or cancellation, report, then removed, then marker complete. + +### Boundaries and invariants to preserve: + +- **Report-then-clear (issue #942).** `CompletePrime` reports through `_logError` and only then executes `_primeTasks.TryRemove(engineName, out _);`. The method body is unchanged. Because the marker is completed in the `finally` that follows the `CompletePrime` call, an awaiter of the handle resumes only after both the report and the removal. +- **Handle identity (issue #942 test).** The handle captured before a prime fault is triggered is `marker.Task`; inside the `logError` sink, before the removal, `GetPrimeTask` returns the same `marker.Task`; after the handle completes, `GetPrimeTask` returns `Task.CompletedTask`. +- **Never-faults contract of `GetPrimeTask`.** The marker is completed only through `SetResult`, so the returned task cannot fault or cancel. +- **At most one concurrent prime per engine.** The check-and-register pair stays atomic under `_primeGate`. `_primeTasks[engineName]` has exactly one writer, so while a marker is registered no other value can replace it, and the only removal of it is its own `CompletePrime`. +- **Single `catch` in the type.** `try`/`finally` adds no `catch`; the click boundary in `HandleToggleClickAsync` remains the only `catch` clause. +- **No new lock and no deadlock path.** `_primeGate` is still held across a dictionary probe, a store, and the synchronous prefix of the prime start, as today. `CompletePrime` takes no lock. `GetPrimeTask` takes no lock, so calling it from inside `EngineActiveAsync` while `_primeGate` is held (as test 1 does) cannot deadlock. +- **Synchronous start.** `ApplyPrimeAsync` is still invoked directly on the calling thread, inside the lock. `GetPressed` still never awaits, blocks, or throws. +- **Success path.** A successful prime's marker stays registered, and complete, for the session, exactly as the continuation handle does today. + +### Dependencies or blocked work: + +**Binding sequencing constraint: issue #942 must merge first.** Issue #942 (branch bug/engine-toggle-prime-fault-logging-test-races-942) edits the same production file and the same fixture and merges into main before this item executes. + +- (a) Execution of this item must not begin until issue #942 has merged into main. The first execution step re-anchors this branch on the then-current origin/main (rebase or merge) and records the origin/main commit it anchored on in the execution record. +- (b) Post-#942 baseline this spec is written against: `CompletePrime` reports through `_logError` and only then calls `_primeTasks.TryRemove(engineName, out _);`; its summary and the `GetPrimeTask` returns element were rewritten by issue #942. This item preserves report-then-clear and leaves the `CompletePrime` body and the `TryRemove` statement unchanged. +- (c) Issue #942 adds an `OnLogError` hook to the private `Harness`, a third partial TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.PrimeFaultOrdering.cs containing `GetPressed_WhenPrimeFaults_PrimeHandleStaysRegisteredUntilFaultIsLogged`, and a matching compile entry. Every assertion of that test must keep passing. +- (d) This item does not modify the main fixture file, the Race partial, the PrimeFaultOrdering partial, or RibbonController.EngineCommands.cs. +- (e) All code citations in this spec, the plan, and the execution record use unique source tokens (research section 7), never line numbers. +- If, after re-anchoring, the `CompletePrime` body does not match the report-then-clear shape described in (b), execution halts and the discrepancy is reported rather than worked around. + +No other blocking work. + +### Implementation strategy (what changes, not sequencing): + +#### Files/modules to change: + +| File | Change | Size budget | +|---|---|---| +| `TaskMaster/Ribbon/EngineToggleStateCoordinator.cs` | modify: marker registration in `StartPrimeIfNeeded`; `StartObservedPrime` signature, body and remarks; `_primeTasks` and `_primeGate` summaries | 415 total lines before issue #942; expected roughly 430 to 445 after both issues; must stay at or below 500 total lines | +| `TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.PrimeRegistration.cs` | create: `public partial class EngineToggleStateCoordinatorTests` with three `[TestMethod]` tests | roughly 170 to 200 total lines; must stay at or below 500 | +| `TaskMaster.Test/TaskMaster.Test.csproj` | add `` adjacent to the existing `` entry (the issue #942 PrimeFaultOrdering entry is expected nearby) | n/a (project file; the 500-line ceiling does not apply) | + +The legacy test project uses explicit `` items; without the entry the new tests would silently not compile or run. + +#### Functions/classes/CLI commands impacted: + +- `EngineToggleStateCoordinator.StartPrimeIfNeeded(string engineName, string controlId)`: registers the marker before starting the prime. +- `EngineToggleStateCoordinator.StartObservedPrime(...)`: return type `Task` becomes `void`; new parameter `TaskCompletionSource marker`; continuation body wraps `CompletePrime` in `try`/`finally` that calls `marker.SetResult(true)`. +- `EngineToggleStateCoordinator.GetPrimeTask(string engineName)`: signature and body unchanged; the value it returns is now the registered marker task instead of the continuation task (see Technical specifications). +- `EngineToggleStateCoordinator.CompletePrime(Task completed, string engineName)`: verify-only; not edited. +- `EngineToggleStateCoordinator._primeTasks`, `EngineToggleStateCoordinator._primeGate`: XML summaries updated; field types unchanged (`ConcurrentDictionary`, `object`). +- No public or cross-assembly API changes. All touched members are `private` or `internal`. + +#### Data flow and validation changes: + +`GetPressed` cache miss, then `StartPrimeIfNeeded`: accessor null returns; otherwise under `_primeGate` the `ContainsKey` probe, marker creation, marker store, then `StartObservedPrime`, which calls `ApplyPrimeAsync` synchronously and attaches the continuation. The continuation runs `CompletePrime` and then completes the marker. No input validation changes. + +#### Error handling and logging updates: + +None to behavior. Faults and cancellations are still observed by `CompletePrime` through the continuation, reported through `_logError` with the unwrapped base exception or a synthesized `TaskCanceledException`, and are not rethrown. No `catch` clause is added. + +#### Rollback/feature-flag considerations (if applicable): + +No feature flag. Rollback is a revert of this item's commits; the issue #942 changes are independent and remain in place. + +### Technical specifications (interfaces/contracts): + +#### Inputs/outputs and formats: + +- **`GetPrimeTask` return contract (changed).** Returns the registration marker, `TaskCompletionSource.Task` created with `TaskCreationOptions.RunContinuationsAsynchronously`, which is registered in `_primeTasks` before the prime starts and completes only after `CompletePrime` has returned (on every outcome: success, fault, cancellation). Returns `Task.CompletedTask` for a null or empty key, or when no marker is registered. The returned task never faults or cancels. The issue #942 returns element (the handle stays incomplete while the marker is registered on the failure path) remains true; after re-anchoring, the `GetPrimeTask` XML documentation is re-read and edited only if a sentence has become false (for example a sentence that names the continuation task as the returned value). +- **`StartObservedPrime` contract (changed).** `void`; receives the already-registered marker; completes it in a `finally` after `CompletePrime` returns. Its remarks replace the sentence beginning "The returned continuation task always completes successfully" with a description of the marker: the continuation task is discarded, and the marker, completed only by `SetResult` after `CompletePrime`, is the value a test awaits. +- **`_primeTasks` field summary (changed).** Replace "The in-flight — or most recently completed — prime per engine key." with wording stating that the value is the registration marker for the engine's prime, registered before the prime starts, removed by `CompletePrime` on failure or cancellation, and retained after success; its presence remains the at-most-one-prime guard and its value remains the handle returned by `GetPrimeTask`. +- **`_primeGate` field summary (changed).** "Held only across a dictionary probe and a task start" becomes "held only across a dictionary probe, the marker registration, and the start of the prime"; "no await occurs inside it" is kept. +- `RunContinuationsAsynchronously` is already used in production TaskMaster code (`NonBlockingDelay`, `AppOlObjects.FolderTreeService`) and exists in the .NET Framework v4.8.1 reference source. It is chosen so that awaiters of the marker resume on their own pool work item rather than inside the coordinator's `finally`; it is not required for correctness. + +#### Required configuration keys and defaults: + +None. + +#### Backward-compatibility expectations: + +- The only production caller, RibbonController.EngineCommands.cs, never calls `GetPrimeTask` and is unaffected. +- The ten existing `GetPrimeTask` call sites in test code (five in the main fixture, five in the Race partial, per research Numeric Derivation Evidence; issue #942 adds more) all await the returned handle; the marker completes after `CompletePrime` on every outcome, so they remain valid. The existing baseline is 22 test methods and 24 test cases before issue #942 (research section 5.3). + +#### Performance constraints (latency/throughput/memory): + +One additional `TaskCompletionSource` allocation per prime. Primes occur at most once per engine per session on success, and once per cache-miss read after a failure. No measurable effect on the synchronous `getPressed` path is expected; no latency target is set. + +## Assumptions, Constraints, Dependencies + +- Assumptions: + - Issue #942 merges with the shape described in Dependencies (b) and (c). If it does not, execution halts per Dependencies. + - `ApplyPrimeAsync` remains an `async` method with no synchronous throw path, so `StartObservedPrime` cannot throw after the marker is registered. +- Constraints: + - Single production file. No scheduler seam, no `ExecuteSynchronously`, no new lock, no new `catch`. + - Tests use MSTest, Moq (the fixture's strict `Mock`), and FluentAssertions. No `Thread.Sleep`, `Task.Delay`, wall-clock waits, retries, temporary files, `[DoNotParallelize]`, `Workers=1`, or scheduler seam. + - The 500-line ceiling applies to both C# files, measured as total lines. +- External dependencies: none beyond the .NET Framework v4.8.1 TPL. + +## Data / API / Config Impact + +- User-facing or API changes: none. After a failed or canceled prime, a later `getPressed` poll now reliably starts a new prime instead of being blocked for the session. +- Data or migration considerations: none. +- Logging/telemetry updates: none to code. Operational effect: after a permanent configuration fault, each cache-miss poll that reaches `StartPrimeIfNeeded` now logs again (previously the stale marker intermittently suppressed repeats). See Rollout and Follow-up. +- Compatibility notes: none. + +## Test Strategy + +Framework: MSTest (`[TestClass]` via the existing partial, `[TestMethod]`), Moq (the existing strict `Harness.Engines`), FluentAssertions. Each test constructs its own `Harness`, so the tests are independent under the repository's class-level parallel execution. All three tests live in `TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.PrimeRegistration.cs` as members of `public partial class EngineToggleStateCoordinatorTests` and reuse the existing private `Harness`, `LoggedError`, `SpamEngine` and `SpamToggleControlId` without adding harness members. + +Bugfix workflow order: the new partial and its csproj entry are added and run against the unchanged (re-anchored, post-#942) production file first, to capture the fail-before evidence; only then is the production file edited. + +### Test 1 — program-order discriminator (carries the fail-before obligation) + +`GetPressed_WhenPrimeStarts_RegistersPrimeHandleBeforeActivationReadRuns` + +- Arrange: `harness.Engines.Setup(x => x.EngineActiveAsync(SpamEngine)).Returns(() => { handleSeenDuringRead = harness.Coordinator.GetPrimeTask(SpamEngine); handleCompletedDuringRead = handleSeenDuringRead.IsCompleted; return Task.FromException(failure); });`. The callback runs synchronously inside `ApplyPrimeAsync` on the test thread. It only records; no assertion runs inside it, because an assertion thrown there would become a prime fault. +- Act: `harness.Coordinator.GetPressed(SpamEngine);` +- Assert: `handleCompletedDuringRead.Should().BeFalse(...)` with a message stating that the prime handle must be registered before the activation read runs; then `await handleSeenDuringRead;`; `harness.Errors` contains exactly one entry whose `Exception` is the same instance as `failure`; `harness.Coordinator.GetPrimeTask(SpamEngine)` is not the same instance as `handleSeenDuringRead`, and its `IsCompleted` is true. +- Before the fix: inside the callback no entry exists, so `GetPrimeTask` returns `Task.CompletedTask` and `handleCompletedDuringRead` is true. The first assertion fails on every run by program order alone. This is the deterministic fail-before test. +- After the fix: the marker is registered and cannot yet be complete, because completing it requires the continuation, which requires the task `ApplyPrimeAsync` has not yet returned.

The defect has no reliable manual reproduction; the program-order test is the reproduction. + +## Acceptance Criteria + +- [ ] AC1 — Execution began only after the report-then-clear fix for the engine-toggle prime fault-logging test races had merged into main; the branch was re-anchored on the then-current origin/main before any code change, and the execution record names the origin/main commit it anchored on and confirms that `CompletePrime` reported through the error sink before its marker removal at that commit. +- [ ] AC2 — `TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.PrimeRegistration.cs` contains the test `GetPressed_WhenPrimeStarts_RegistersPrimeHandleBeforeActivationReadRuns`, which records from inside the `EngineActiveAsync` setup callback the handle returned by `GetPrimeTask` and its `IsCompleted` value without asserting inside the callback, then asserts outside the callback that the recorded handle was not completed, awaits it, asserts exactly one logged error whose exception is the injected failure instance, and asserts that `GetPrimeTask` afterwards returns a different, completed task. +- [ ] AC3 — Fail-before evidence: the fail-before projection named in the Test Strategy records a run of the program-order test against the unchanged production file in which it fails on the not-completed-during-read assertion with that assertion's message, and not by a compile error, an assembly-load error, or a timeout. +- [ ] AC4 — Pass-after evidence: the pass-after projection named in the Test Strategy records the program-order test and both re-prime tests passing after the production change. +- [ ] AC5 — The test `GetPressed_AfterPrimeFaultsSynchronously_LaterReadStartsNewPrime` passes: after a first activation read that returns an already-faulted task, a later `GetPressed` starts a new prime, `EngineActiveAsync` is verified as called exactly twice, the toggle then reads as pressed, the mapped control is invalidated exactly once, and exactly one error carrying the injected failure instance is logged. +- [ ] AC6 — The test `GetPressed_AfterPrimeIsCanceledSynchronously_LaterReadStartsNewPrime` passes with the same assertions as the faulted re-prime test, except that the first activation read returns an already-canceled task and the single logged exception is assignable to `OperationCanceledException`. +- [ ] AC7 — In `TaskMaster/Ribbon/EngineToggleStateCoordinator.cs`, `StartPrimeIfNeeded` creates a boolean `TaskCompletionSource` with `TaskCreationOptions.RunContinuationsAsynchronously` and stores its task in `_primeTasks` inside the existing `_primeGate` lock block, after the `ContainsKey` check and before `StartObservedPrime` is called; `StartObservedPrime` returns `void`, receives that completion source as a parameter, keeps `CancellationToken.None`, `TaskContinuationOptions.None` and `TaskScheduler.Default`, and completes the marker only through `SetResult` inside a `finally` block that follows the `CompletePrime` call in the continuation. +- [ ] AC8 — Report-then-clear is preserved: the `CompletePrime` method, including its `_primeTasks.TryRemove(engineName, out _);` statement and its XML documentation, is identical to the re-anchored origin/main, and `GetPressed_WhenPrimeFaults_PrimeHandleStaysRegisteredUntilFaultIsLogged` passes with no assertion changed. +- [ ] AC9 — At most one concurrent prime per engine: the `ContainsKey` check and the marker store occur within a single `_primeGate` lock block with no other writer to `_primeTasks` in the type, and `GetPressed_OnCacheMissWithEnginesAvailable_StartsExactlyOnePrime` passes unmodified. +- [ ] AC10 — The diff of `TaskMaster/Ribbon/EngineToggleStateCoordinator.cs` against the re-anchored origin/main adds no `catch` clause, no `lock` statement, and no `Monitor`, `SemaphoreSlim`, `Mutex` or `ReaderWriterLockSlim` usage. +- [ ] AC11 — Every test method in the main coordinator fixture, the Race partial and the PrimeFaultOrdering partial passes, and those three test files and RibbonController.EngineCommands.cs are byte-identical to the re-anchored origin/main. +- [ ] AC12 — The `_primeTasks` field summary describes the registration marker registered before the prime starts, the `_primeGate` field summary names the marker registration among the operations it is held across, the `StartObservedPrime` remarks describe the marker instead of the returned continuation, the production file no longer contains the phrase "The returned continuation task always completes successfully", and `StartPrimeIfNeeded` carries a why-comment explaining that registration precedes the start. +- [ ] AC13 — The new partial uses MSTest, the existing strict Moq harness and FluentAssertions, constructs a fresh harness in each test, and contains no `Thread.Sleep`, `Task.Delay`, `SpinWait`, polling loop, retry, wall-clock read, temporary file, `DoNotParallelize` or other parallelism attribute, and no custom `TaskScheduler` or scheduler seam. +- [ ] AC14 — A single final toolchain pass succeeds in order with no step failing or rewriting a file: `dotnet tool run csharpier check .`, the analyzer rebuild with analyzers and code-style enforcement enabled, the nullable rebuild with warnings treated as errors, and the coverage-enabled MSTest run, each exactly as named in CLAUDE.md, recorded in the toolchain projection named in the Test Strategy. When the plan's baseline stall probe observes the known local shell-icon test stall, the coverage-enabled run is the coverage runner's own inner collector invocation with those four test classes excluded and the vstest hang-blame switch appended, post-processed by the runner's own helpers and floor checks, and the toolchain projection records that route and the probe result. +- [ ] AC15 — Coverage: no changed line in `TaskMaster/Ribbon/EngineToggleStateCoordinator.cs` loses coverage relative to the baseline projection, `StartPrimeIfNeeded` and `StartObservedPrime` each reach at least ninety percent line coverage in the coverage projection, and the repository summary line is recorded beside its baseline value; when the two runs' repository line denominators differ by at most one percent, the post-change repository line rate is not more than half a percentage point below the baseline rate, and when they differ by more, the merged repository figures are not comparable across runs and are recorded without a gate. +- [ ] AC16 — The diff adds no `.trx`, `.xml` or `.coverage` file; all committed test and coverage evidence is Markdown projections inside this feature folder. +- [ ] AC17 — The diff against the re-anchored origin/main is limited to the three code files `TaskMaster/Ribbon/EngineToggleStateCoordinator.cs`, `TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.PrimeRegistration.cs` and `TaskMaster.Test/TaskMaster.Test.csproj`, plus files inside this feature folder and the inherited promotion record for this item listed in the Write Set. +- [ ] AC18 — `TaskMaster.Test/TaskMaster.Test.csproj` contains a `Compile Include` entry for the new PrimeRegistration partial, and `TaskMaster/Ribbon/EngineToggleStateCoordinator.cs` and `TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.PrimeRegistration.cs` are each at or below the repository five-hundred-line ceiling measured as total lines; the project file is exempt from the ceiling. + +## Risks & Mitigations + +- **Issue #942 lands in a different shape than assumed.** Mitigation: Dependencies (a) and (b) and AC1 require re-anchoring and verifying the `CompletePrime` shape before any change; a mismatch halts execution. +- **Test 1 passes vacuously before the fix** (for example, if the callback were never invoked, both recorded values would stay at defaults). Mitigation: initialize `handleCompletedDuringRead` so that a never-invoked callback fails the assertion (for example to true, or assert the recorded handle is non-null), and AC3 requires captured fail-before evidence showing the specific assertion failing. +- **Fail-before run misread.** A compile failure or an assembly-load failure (empty message, sub-millisecond duration) is not a valid fail-before. Mitigation: AC3 excludes those outcomes explicitly; the new tests use only existing `internal` API, so they compile against the unchanged production file. +- **Marker leaks if `StartObservedPrime` ever throws after registration.** `ApplyPrimeAsync` is `async`, so faults go into its task, and `ContinueWith` with valid arguments does not throw. Mitigation: record this as an assumption; any future change that adds a synchronous throw path before the continuation is attached must also remove the marker. +- **Throwing `logError` sink.** Under report-then-clear, a throwing sink skips `TryRemove`; the marker still completes (`finally`) but stays registered, and the continuation task faults unobserved. Production sink is `logger.Error`, so likelihood is low. Mitigation: out of scope; recorded as a follow-up. +- **Analyzer findings on the discarded continuation.** Mitigation: use an explicit discard (`_ = ...`), which satisfies MA0134; the analyzer rebuild in AC14 is the gate. +- Rollback: revert this item's commits; issue #942 is unaffected. + +## Rollout & Follow-up + +- Release/rollout steps: standard PR into main after issue #942 has merged; no configuration, migration or flag. +- Post-fix monitoring: none required beyond the add-in log. +- Out-of-scope follow-ups (recorded here only; this item files no issue): + 1. **Throwing `logError` sink leaves a stale marker.** Under report-then-clear, a sink that throws skips the removal, reproducing this symptom by a different cause. With this fix the marker still completes, but the continuation faults unobserved. Candidate for a separate bug. + 2. **Log volume after a permanent configuration fault.** `AsyncLazy` caches the configuration fault, so each cache-miss `getPressed` poll re-primes and logs again. Previously the stale marker intermittently suppressed repeats; after this fix every poll that reaches `StartPrimeIfNeeded` logs. A back-off or a `ResetConfigAsyncLazy`-based recovery is a separate decision. +- Links: issue #944 (https://github.com/drmoisan/TaskMaster/issues/944); upstream dependency issue #942; origin NB-2 in the issue #735 code review. + +## Write Set + +- `TaskMaster/Ribbon/EngineToggleStateCoordinator.cs` (modify) +- `TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.PrimeRegistration.cs` (create) +- `TaskMaster.Test/TaskMaster.Test.csproj` (modify: one compile entry) +- `docs/features/active/2026-09-30-engine-toggle-prime-marker-registration-races-removal-944/**` (this feature folder: plan, evidence, spec updates) +- `docs/features/potential/promoted/2026-09-30-engine-toggle-prime-marker-registration-races-removal.md` (inherited promotion record) diff --git a/docs/features/potential/promoted/2026-09-30-engine-toggle-prime-marker-registration-races-removal.md b/docs/features/potential/promoted/2026-09-30-engine-toggle-prime-marker-registration-races-removal.md new file mode 100644 index 000000000..f1b436d4e --- /dev/null +++ b/docs/features/potential/promoted/2026-09-30-engine-toggle-prime-marker-registration-races-removal.md @@ -0,0 +1,62 @@ +# engine-toggle-prime-marker-registration-races-removal (Issue #944) + +- Date captured: 2026-09-30 +- Author: Dan Moisan +- Status: Promoted -> docs/features/active/engine-toggle-prime-marker-registration-races-removal/ (Issue #944) + +> Automation note: Keep the section headings below unchanged; the promotion tooling maps each of them into the GitHub bug issue template. + +- Issue: #944 +- Issue URL: https://github.com/drmoisan/TaskMaster/issues/944 +- Last Updated: 2026-09-30 +## Summary + +In `EngineToggleStateCoordinator`, a prime that completes synchronously in a non-success state can run `CompletePrime`'s marker removal before `StartPrimeIfNeeded` registers that marker.

The first P3-T8 attempt exited 1 with 7325 of 7327 passed; the two failures, `QuickFiler.Controllers.Tests.QfcDatamodelLivenessTests.RemainingLoadActive_AcrossAsyncVoidFirstAwait_StaysTrueWhileLoaderProduces` (00:00:07.04) and `QuickFiler.Controllers.Tests.QfcDatamodelLivenessTests.RemainingLoadActive_AfterLoaderCompletes_BecomesFalse` (00:00:05.02), are five-second wall-clock waits in a QuickFiler test class this item neither changes nor covers, and are recorded verbatim in FEATURE/evidence/qa-gates/coverage-summary.md. The coordinator approved one full restart of P3-T1 through P3-T8 on that basis only, with zero failures required in the restart, no second restart, and no change to AC14 wording. This is a single re-measurement of a gate, not a fix, and it sets no precedent.

Measured after the merge: `git diff --quiet ANCHOR-SHA MAIN-MERGE-SHA` over TaskMaster/Ribbon, TaskMaster.Test/Ribbon, TaskMaster.Test/TaskMaster.Test.csproj and TaskMaster/TaskMaster.csproj exits 0; `git diff --name-status ANCHOR-SHA HEAD` lists 123 paths, 80 of them outside this item, and the ANCHOR-SHA-to-HEAD added-path list carries 2 `.xml` files (the item-929 JaCoCo projections), so P3-T14 would report `FOOTPRINT OUTSIDE AC17` and P3-T12 would report `RAW-DOCS-COMMITTED: 2` for content this item did not author. `git diff --name-status MAIN-MERGE-SHA HEAD` lists 43 paths: the three code paths, the promotion record and the feature folder. Negative control: the same two checks run against ANCHOR-SHA fail on the item-929 paths, which shows that the footprint and raw-document checks still detect out-of-scope and raw-document paths; against MAIN-MERGE-SHA they remain able to fail on any such path this item adds.

Coordinator extension (revision round 3, applied once and setting no precedent): the same single pass-2 restart is also admitted when every `FAILED-SET:` name of the first attempt belongs to the test class `QuickFiler.Controllers.Tests.QfcDatamodelLivenessTests`, which is in QuickFiler.Test, a project this item neither changes nor covers; the first attempt of 2026-09-30 used this extension, so pass 2 must reach branch (a) with an empty `FAILED-SET:`, and any pass-2 failure of any test stops the item with no further re-run. When pass 2 runs, the top-level `Timestamp:`, `Command:`, `EXIT_CODE:` and `Output Summary:` fields of FEATURE/evidence/qa-gates/coverage-summary.md are rewritten with pass 2's values after pass 2's P3-T8 completes, the trailing ` — STOPPED` of the artifact's first heading is removed in the same rewrite, the first attempt's exit code is kept as `FIRST-ATTEMPT-EXIT-CODE:` beside `FIRST-ATTEMPT-FAILED-SET:`, and no `ExpectedExitCode:` is added, so the first `EXIT_CODE:` an evidence reader encounters is the clean run's. No other artifact pass 2 appends to needs the same rewrite: pass 2 runs only when P3-T1 through P3-T7 each exited 0 on pass 1 (any other outcome stops the run first), so the first `EXIT_CODE:` of each of their artifacts, and of the four artifacts P3-T2 and P3-T7 append sections to (whose top-level fields were written by the passing P1-T1, P2-T6, P2-T7 and P2-T4 runs), already records a clean run. - Acceptance, all required: branch (a) of P0-T18's branch rule (exit 0, both floors met, `FAILED-SET:` empty) on the recorded attempt; `SEQUENCE_FILES: 0` (DIRECT) and `TRX_PRESENT: True`; the `Output Summary:` holds at most 20 lines, as P0-T18 requires; the summary block in the `Details:` section reports `failed 0`; `COORD-CLASS-NODES: 1` in the `Details:` section; the three `METHOD` rows are present in the `Output Summary:`; the projection block in the `Details:` section contains the `TaskMaster` package with both counters. `RESULT`-level proof that the new tests executed is taken from P3-T7, because the runner's summary carries counts and failed names only.

Registering the marker under `_primeGate` before `ApplyPrimeAsync` is invoked closes the window in which a synchronously faulted or canceled prime's continuation could run `CompletePrime`'s `TryRemove` before the store, and it does so without a new lock, a scheduler seam or a `catch`. The keyed removal in `CompletePrime` cannot remove a newer marker, because a newer marker for the same key can only be registered after the older marker's removal has already executed (analysis in CR-A below). The three new tests are policy-compliant (MSTest, the existing strict Moq harness, FluentAssertions, no timing constructs, no temporary files) and the fail-before evidence is a genuine program-order failure rather than a compile or load failure.

Keyed removal cannot remove a newer marker + +`CompletePrime` identifies the entry to remove by key only: `_primeTasks.TryRemove(engineName, out _);` (line 381). This is safe under the type's invariants for the following reason, verified by reading every write and removal site in the file: + +1. `_primeTasks` has exactly one write site, line 286, executed under `lock (_primeGate)` immediately after `if (_primeTasks.ContainsKey(engineName)) return;` (line 274). A marker for key K can therefore be registered only while no entry for K exists. +2. `_primeTasks` has exactly one removal site, line 381, inside `CompletePrime`, which runs exactly once per prime as the `ContinueWith` continuation of that prime's `ApplyPrimeAsync` task. +3. Consider marker A for key K and a later marker B for K. B's registration (step 1) required `ContainsKey(K)` to be false, which — since A's registration preceded A's prime start and the only removal path is step 2 — means A's `TryRemove` had already executed. A's continuation never touches the dictionary after that statement (only `marker.SetResult(true)` in the `finally` remains). So A's removal precedes B's registration in the causal order established by the `ConcurrentDictionary` operations themselves, and A cannot remove B. +4. On the success path `CompletePrime` returns at line 370 without removing, so the marker is retained and `ContainsKey` blocks any re-prime for the session — the pre-existing intended behaviour (spec state model). + +Identity-conditional removal (`ICollection>.Remove`) is therefore not needed, as research section 4.4 concluded; the spec correctly excludes it. + +### CR-B. The race the fix closes + +At the anchor, `_primeTasks[engineName] = StartObservedPrime(...)` evaluated the right-hand side first: `ApplyPrimeAsync` ran to its first await, an already-faulted `EngineActiveAsync` task made the async method's task fault synchronously, and `ContinueWith(..., TaskContinuationOptions.None, TaskScheduler.Default)` queued the continuation to the thread pool before the store executed. A pool thread could run `TryRemove(K)` (no entry yet, no-op) before the registering thread stored the finished continuation task, leaving a permanent stale entry. With the fix, the store at line 286 precedes the call at line 287, so any continuation, on any thread, finds the marker it is meant to remove. Test 1 pins this by observing `GetPrimeTask(K).IsCompleted == false` from inside the activation read. + +### CR-C. Marker completion semantics + +- `marker.SetResult(true)` (line 320) is the only completion call (`SetException`/`SetCanceled`/`TrySet*` counts are 0), so the handle returned by `GetPrimeTask` can never fault or cancel; the `` contract "never faults" holds. +- The `finally` guarantees completion even if `CompletePrime` throws (see the Follow-up on a throwing sink), so no awaiter can hang on the marker. +- `TaskCreationOptions.RunContinuationsAsynchronously` prevents an awaiter's continuation from running inline inside the coordinator's `finally` on the pool thread; correctness does not depend on it, but it keeps the coordinator's continuation short and avoids re-entrancy from test code. The option is available on .NET Framework 4.8 and already used in two production files. +- Report-then-clear (#942) is preserved: the marker is completed only after `CompletePrime` returns, and `CompletePrime` still logs (line 380) before removing (line 381). The #942 test `GetPressed_WhenPrimeFaults_PrimeHandleStaysRegisteredUntilFaultIsLogged` passes unchanged in all five recorded runs. +- No deadlock path: `GetPrimeTask` takes no lock, so test 1's call from inside `EngineActiveAsync` while `_primeGate` is held (the prime starts synchronously inside the lock) cannot block. `CompletePrime` takes no lock. + +### CR-D. Assumption recorded by the spec + +`ApplyPrimeAsync` is `async`, so it has no synchronous throw path after the marker is registered, and `ContinueWith` with valid arguments does not throw; a future change that adds a synchronous throw before the continuation is attached must also remove the marker. The spec records this under Risks; the review agrees and adds nothing. + +## Test Review + +| Test | Policy check | Result | +|---|---|---| +| `GetPressed_WhenPrimeStarts_RegistersPrimeHandleBeforeActivationReadRuns` (lines 31-75) | Records only inside the mock callback (lines 44-46), asserts only outside it (53-74); `handleCompletedDuringRead` initialised to `true` so a never-invoked callback fails the first assertion (line 39, spec Risk 2); awaits the recorded marker rather than polling; asserts identity change and completion afterwards.

The fix is confined to `StartPrimeIfNeeded` and `StartObservedPrime`, preserves #942's report-then-clear ordering byte for byte, adds no lock or catch, and is pinned by a deterministic program-order test whose fail-before run is recorded. Coverage of the changed methods is 100% and the repository summary did not regress.

The pre-merge anchor was `b305903e275b8abf58e8e65831c189f517568fe4` (ANCHOR-SHA); the two differ by no path under `TaskMaster/Ribbon`, `TaskMaster.Test/Ribbon`, `TaskMaster.Test/TaskMaster.Test.csproj` or `TaskMaster/TaskMaster.csproj` (plan R3-2 measurement). +- Work mode: `full-bug` (issue.md line 12); AC source `spec.md` only. +- Review worktree: the item worktree `.claude/worktrees/agent-a308c11880eff133b` under the session checkout (all reads rooted here; nothing written outside the feature folder). +- Review mechanics: no Bash tool was available. Every observation below was made with Read, Grep and Glob against files on disk: the two changed C# files, the project file, the main fixture (for the reused `Harness` members), the git-ignored post-processed Cobertura documents `coverage/final-944.cobertura.xml` and `coverage/baseline-944.cobertura.xml`, and the 42 Markdown evidence artifacts.

Three new MSTest/Moq/FluentAssertions regression tests in a new partial cover the ordering invariant (program-order fail-before captured), the faulted re-prime and the canceled re-prime. The four-step C# toolchain passed in a single clean pass (pass 2 of the Phase 3 loop; pass 1 stopped on two pre-existing wall-clock QuickFiler test failures in a project the item does not touch, and a coordinator-ruled single restart was recorded as R3-1). First-party coverage 85.32% lines / 79.73% branches (baseline 85.31% / 79.71%); the coordinator class is 157/157 lines and 37/38 branches, and all 17 changed executable lines have hits, verified by this review directly in the raw Cobertura document. No production file is excluded from coverage, no suppression was added, no raw test or coverage document was committed, and the evidence tree carries no absolute host path, account name or machine name (0 hits on this review's own sweep). + +Rejected scope narrowing: none.

Gaps and Exceptions + +Non-blocking notes: + +- NB-1 (context, already routed by the coordinator): pass 1 of the final coverage run failed two `QuickFiler.Controllers.Tests.QfcDatamodelLivenessTests` tests on five-second wall-clock waits in a project this item does not modify; the coordinator approved one full loop restart (R3-1). The wall-clock waits themselves (`SpinWait.SpinUntil(..., 5 s)`, `Task.Wait(5 s)`) are the flakiness the coordinator is filing separately; they are not this item's finding. +- NB-2 (evidence): the P0-T16 stall probe returned `REPRODUCES` because one shell-icon test failed (`Win32 handle that was passed to Icon is not valid`), not because a hang occurred (`SEQUENCE_FILES: 0`). The plan's rule treats any non-clean probe as REPRODUCES, so the DIRECT route excluded the four `UtilitiesCS.Test` shell-icon classes from the local coverage run. Those classes execute in CI; the PR-time CI run remains the gate for them. The exclusion does not touch any assembly this item changes. +- NB-3 (evidence): the coverage baseline was measured at ANCHOR-SHA and the final at HEAD after merging main `66afa6372`, so the repository-wide delta includes item-929 content; the per-file and per-method figures carry the no-regression conclusion (section 1.2.2). +- NB-4 (procedural): no copy of the coverage document exists at the review hook's canonical path `artifacts/csharp/coverage.xml`; the artifact was read at `coverage/final-944.cobertura.xml` and the floors were applied manually. No remediation is requested: the repository forbids committing the raw document and the on-disk document plus the committed projection satisfy the evidence model. + +Follow-up items (out of this item's scope by spec; recommend promotion to issues so they survive the feature-folder archive): + +- FU-1: a throwing `logError` sink skips `_primeTasks.TryRemove` under report-then-clear; with this fix the marker still completes but stays registered, so the engine cannot re-prime for the session, and the discarded continuation task faults unobserved (spec Rollout item 1). +- FU-2: after a permanently faulted configuration load, every cache-miss `getPressed` poll that reaches `StartPrimeIfNeeded` now re-primes and logs again; a back-off or `ResetConfigAsyncLazy`-based recovery is a separate decision (spec Rollout item 2). +- FU-3: `GetPrimeTask` `` (production lines 244-245) still opens with "The prime task"; the value is now the registration marker that completes after the prime's outcome has been observed. Plan decision D-3 ruled the sentence not false and froze the method; a one-sentence precision edit is a candidate for the next touch of the file. + +Assumptions made because git could not be run in this session: + +- The delta between `594c3eb9b` (PRE-FINAL-COMMIT-HEAD, the tree P3-T12/P3-T14 measured) and HEAD `1f3614deb` is the P3-T35 feature-folder commit only. Basis: plan D-10 (the P3-T35 commit stages feature-folder paths only), the P3-T14 porcelain showing no uncommitted path under `TaskMaster/` or `TaskMaster.Test/`, and the caller's statement of the diff. +- Byte-identity of the three protected test partials and `RibbonController.EngineCommands.cs` to main rests on the executor's `git diff --exit-code` results (`PROTECTED_FILES_DIFF_EXIT=0` on both passes) and on their absence from the caller-supplied diff. + +## 9. Summary of Changes + +- `TaskMaster/Ribbon/EngineToggleStateCoordinator.cs` (+34/-12): `_primeGate` and `_primeTasks` summaries reworded; `StartPrimeIfNeeded` creates a `TaskCompletionSource` (`RunContinuationsAsynchronously`), stores `marker.Task` in `_primeTasks` under the existing lock after the `ContainsKey` probe, then calls `StartObservedPrime(engines, engineName, controlId, marker)`; `StartObservedPrime` becomes `void`, discards the `ContinueWith` task (`_ =`) and wraps `CompletePrime` in `try`/`finally { marker.SetResult(true); }` with the three continuation arguments unchanged. `CompletePrime`, `ApplyPrimeAsync`, `GetPrimeTask` untouched. +- `TaskMaster.Test/Ribbon/EngineToggleStateCoordinatorTests.PrimeRegistration.cs` (new, 175 lines): three regression tests reusing the fixture's `Harness`, `LoggedError`, `SpamEngine`, `SpamToggleControlId`. +- `TaskMaster.Test/TaskMaster.Test.csproj` (+1/-0): compile entry for the new partial. +- `docs/features/potential/promoted/2026-09-30-engine-toggle-prime-marker-registration-races-removal.md` (inherited promotion record, unchanged by the plan) and the feature folder (spec, issue, research, plan, 38 evidence artifacts). + +## 10.
