No temporary files, external dependencies, or wall-clock waits are used. +- [x] AC-2: `FolderBreadcrumbBridgeRouter.SetSuggestionsAsync` no longer exposes a transient cleared or partially-populated model: upgraded rows are built into a local collection and swapped into `BreadcrumbStateModel` atomically at the end, so the observable row count never drops below the pre-upgrade count while the upgrade is in flight. +- [x] AC-3: The breadcrumb readback contract (`FolderContains`, `GetSelectedFolder`, `GetFolderItems`, `SelectRow`) returns pre-upgrade-consistent results at every point during an in-flight upgrade, and the host-selected index survives the swap (the `UpgradeSuggestionsAsync` re-selection preserves a selection made after `SetSuggestions` returned). +- [x] AC-4: Completed-upgrade behavior is unchanged: suggestion rows carry ancestor chains and probabilities, unresolvable scored rows fall back to plain rows, non-scored rows remain plain verbatim rows, and all existing `FolderBreadcrumbBridgeRouter` / `BreadcrumbBridgeCoordinator` / `QfcItemController` tests continue to pass. +- [x] AC-5: The full C# toolchain passes in order (CSharpier format, .NET analyzers build, nullable build, MSTest via vstest.console.exe) with zero regressions relative to the Phase 0 baseline, and new/changed code meets the >= 90% coverage target. + +## Next Step + +- [x] Promote to GitHub issue (bug-report template) +- [x] Move to active fix folder / branch diff --git a/docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/plan.2026-07-20T21-41.md b/docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/plan.2026-07-20T21-41.md new file mode 100644 index 00000000..18b29234 --- /dev/null +++ b/docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/plan.2026-07-20T21-41.md @@ -0,0 +1,60 @@ +# 2026-07-20-breadcrumb-suggestions-upgrade-race (Plan) + +- **Issue:** #398 +- **Parent (optional):** none +- **Owner:** drmoisan +- **Branch:** bug/breadcrumb-suggestions-upgrade-race-398 (off origin/main at cd6362f0) +- **Work Mode:** minor-audit (small-path C# bug fix) +- **Requirements source (sole):** docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/issue.md (`## Acceptance Criteria` AC-1..AC-5 only) +- **Last Updated:** 2026-07-20T21-41 +- **Status:** Draft +- **Version:** 1.0 + +**Fail-closed evidence rule:** Include explicit baseline artifact tasks, final-QA artifact tasks, and coverage-comparison tasks for the in-scope C# language.

Any Phase 0 task whose artifact is absent or incomplete MUST remain unchecked. + +**Evidence-path invariant:** All evidence paths resolve to `docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/evidence//`. Non-canonical locations (`artifacts/baselines/`, `artifacts/qa/`, `artifacts/coverage/`, etc.) are rejected. + +**Root cause (confirmed):** `BreadcrumbBridgeCoordinator.SetSuggestions` (QuickFiler/Viewers/BreadcrumbBridgeCoordinator.cs:78-93) populates N plain rows synchronously via `_router.SetItems`, then assigns `SuggestionsUpgrade = UpgradeSuggestionsAsync(rows)` without awaiting. `UpgradeSuggestionsAsync` enters `FolderBreadcrumbBridgeRouter.SetSuggestionsAsync` (UtilitiesCS/OutlookObjects/Folder/FolderBreadcrumbBridgeRouter.cs:43-83), which calls `_model.Clear()` BEFORE its first `await`, then re-adds rows one at a time on thread-pool continuations. The host `QfcItemController.AssignFolderComboBox` (QuickFiler/Controllers/QfcItemController.FolderHandling.cs:182-205) then calls `SetFolderSelectedIndex(FolderArray.Length == 1 ? 0 : 1)` against the transiently cleared/partial model; `BreadcrumbStateModel.SelectRow(1)` (UtilitiesCS/OutlookObjects/Folder/BreadcrumbStateModel.cs:233-246) throws `ArgumentOutOfRangeException`, aborting the load. Distinct from issue #392. + +**Fix direction (approved by maintainer):** Eliminate the mid-rebuild empty window in `FolderBreadcrumbBridgeRouter.SetSuggestionsAsync`: resolve each row's ancestor chain into a LOCAL collection first (no model mutation while awaiting), then swap the completed row set into `BreadcrumbStateModel` atomically at the end (Clear + re-add back-to-back with no intervening `await`, or a dedicated `ReplaceRows` seam on the model). Preserve completed-upgrade semantics exactly (suggestion rows carry chains/probabilities; unresolvable scored rows fall back to plain rows; non-scored rows plain verbatim). Re-read the selected index AFTER the swap in `UpgradeSuggestionsAsync` if needed so a host selection made after `SetSuggestions` returns survives. Expected production surface: 1-3 files (FolderBreadcrumbBridgeRouter.cs; possibly BreadcrumbBridgeCoordinator.cs and/or BreadcrumbStateModel.cs for the atomic-replace seam). + +**net48 constraint:** No init-only setters, `record`, or `record struct` (no `IsExternalInit` polyfill on net48). Use plain readonly structs/classes only in any new type. + +**Test constraints:** MSTest + Moq + FluentAssertions. Deterministic fakes only: a fake `IFolderHierarchyProvider` gated by `TaskCompletionSource` (no `Thread.Sleep`, `Task.Delay`, wall-clock waits, or timing loops), no temporary files, no external services. Both test projects (UtilitiesCS.Test, QuickFiler.Test) are legacy `packages.config` projects with explicit `` items; any new test `.cs` file MUST be wired into its `.csproj`. + +--- + +### Phase 0 — Policy Reads & Baseline Capture + +- [x] [P0-T1] Read the required policies in policy-compliance-order (CLAUDE.md; .claude/rules/general-code-change.md; .claude/rules/general-unit-test.md; .claude/rules/csharp.md as the C# code-change and C# unit-test policy) and write `docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/evidence/other/phase0-instructions-read.md` containing `Timestamp:`, `Policy Order:`, and the explicit list of files read. Acceptance: file exists with all three fields populated. +- [x] [P0-T2] Record the branch/commit baseline to `docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/evidence/baseline/branch-commit.2026-07-20T21-41.md` with `Timestamp:`, `Command:` (`git rev-parse HEAD` and `git rev-parse --abbrev-ref HEAD`), `EXIT_CODE:`, and `Output Summary:` naming branch `bug/breadcrumb-suggestions-upgrade-race-398` and the head commit. Acceptance: file exists with all fields populated. +- [x] [P0-T3] Run the baseline formatter check `dotnet tool run csharpier --check .` (or `csharpier --check .`) and write `docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/evidence/baseline/csharpier.2026-07-20T21-41.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:`. Acceptance: artifact records the pre-change formatter state. +- [x] [P0-T4] Run the baseline analyzer build `msbuild TaskMaster.sln /t:Build /p:Configuration=Debug /p:Platform="Any CPU" /p:EnableNETAnalyzers=true /p:EnforceCodeStyleInBuild=true` and write `docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/evidence/baseline/analyzer-build.2026-07-20T21-41.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:` (warning/error counts). Acceptance: artifact records the pre-change analyzer state. +- [x] [P0-T5] Run the baseline nullable build `msbuild TaskMaster.sln /t:Build /p:Configuration=Debug /p:Platform="Any CPU" /p:Nullable=enable /p:TreatWarningsAsErrors=true` and write `docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/evidence/baseline/nullable-build.2026-07-20T21-41.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:`. Note in the summary any pre-existing nullable errors in vendored `SVGControl.csproj` (baseline-exempt, tracked separately); first-party deltas are compared against this baseline. Acceptance: artifact records the pre-change nullable state including the vendored-project exemption note. +- [x] [P0-T6] Run the baseline test suite with coverage `vstest.console.exe UtilitiesCS.Test\bin\Debug\UtilitiesCS.Test.dll QuickFiler.Test\bin\Debug\QuickFiler.Test.dll /EnableCodeCoverage` (when discovering assemblies recursively, exclude any path under `.claude\worktrees\`) and write `docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/evidence/baseline/tests-coverage.2026-07-20T21-41.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:` including numeric pass/fail counts and the baseline line and branch coverage percentages for the touched files (FolderBreadcrumbBridgeRouter.cs, BreadcrumbBridgeCoordinator.cs, BreadcrumbStateModel.cs). Acceptance: artifact records numeric baseline coverage values. + +### Phase 1 — Constrained Small-Path Fix & Regression Tests + +- [x] [P1-T1] [expect-fail] Add a deterministic coordinator-level regression test to `QuickFiler.Test\Viewers\BreadcrumbBridgeCoordinatorTests.cs` that constructs a `BreadcrumbBridgeCoordinator` with a fake `IWebViewMessenger` and a fake `IFolderHierarchyProvider` whose `ResolveLeafKeyAsync` is gated by a `TaskCompletionSource`, supplies two or more scored `FolderRow` suggestions, calls `SetSuggestions(rows)`, then calls `SelectRow(1)` while `SuggestionsUpgrade` is still in flight, and asserts (FluentAssertions) that `SelectRow(1)` does NOT throw and the selection is applied. This reproduces AC-1. Acceptance: the test method compiles and is present. +- [x] [P1-T2] Wire any new test `.cs` file created in Phase 1 into its project via an explicit `` item (`QuickFiler.Test\QuickFiler.Test.csproj` and/or `UtilitiesCS.Test\UtilitiesCS.Test.csproj`). If the tests are added to existing test `.cs` files already listed in the csproj, record "no new file — no csproj change required" in the task note. Acceptance: every new test file is referenced by its csproj (or the no-new-file note is recorded). +- [x] [P1-T3] [expect-fail] Build the test projects and run only the new regression test(s) via `vstest.console.exe QuickFiler.Test\bin\Debug\QuickFiler.Test.dll /Tests:` and write the failing run to `docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/evidence/regression-testing/fail-before.2026-07-20T21-41.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:` showing the `ArgumentOutOfRangeException` ("Row selection requires -1 or an index in [0, 0]", actual 1). Acceptance: artifact records the pre-fix failure with the expected exception message. +- [x] [P1-T4] Add deterministic router-level invariant tests to `UtilitiesCS.Test\OutlookObjects\Folder\FolderBreadcrumbBridgeRouterTests.cs` proving AC-2 and AC-3: with a `TaskCompletionSource`-gated fake `IFolderHierarchyProvider`, an in-flight `SetSuggestionsAsync` never lets `Model.Rows.Count` drop below the pre-upgrade count, and `FolderContains` / `GetSelectedFolder` / `SelectRow` return pre-upgrade-consistent results at every point during the in-flight upgrade. Acceptance: the test methods compile and are present (they will pass only after P1-T5). +- [x] [P1-T5] Implement the atomic-swap fix in `UtilitiesCS\OutlookObjects\Folder\FolderBreadcrumbBridgeRouter.cs` `SetSuggestionsAsync`: resolve each row's ancestor chain into a local collection with no mutation of `_model` while awaiting, then apply the completed row set to `BreadcrumbStateModel` in a single synchronous block with no intervening `await` (Clear + re-add back-to-back, or a new `ReplaceRows` seam on `BreadcrumbStateModel`). Preserve exact completed-upgrade semantics (suggestion rows with chains/probabilities; unresolvable scored rows fall back to plain rows carrying the score's folder path; non-scored rows plain verbatim). Acceptance: no `_model` mutation occurs before or between awaits in the method. +- [x] [P1-T6] If P1-T5 introduces an atomic-replace seam, add it to `UtilitiesCS\OutlookObjects\Folder\BreadcrumbStateModel.cs` as a single method (e.g., `ReplaceRows(IReadOnlyList)` or an internal builder) that clears and re-adds rows synchronously without an intervening await, using plain classes only (no init-only setters / records per the net48 constraint). If no new seam is needed, record "no model seam required" in the task note. Acceptance: the seam exists and is synchronous, or the no-seam note is recorded. +- [x] [P1-T7] In `QuickFiler\Viewers\BreadcrumbBridgeCoordinator.cs` `UpgradeSuggestionsAsync`, re-read the selected index AFTER the router swap (rather than only capturing it before the rebuild) so a host selection made after `SetSuggestions` returns survives, keeping the change minimal. If analysis in P1-T5 shows the pre-capture already survives the atomic swap, record "no coordinator change required — selection survives swap" with justification. Acceptance: post-swap selection is preserved, or the no-change justification is recorded. +- [x] [P1-T8] Rebuild the test projects and re-run the P1-T1 regression test and the P1-T4 router invariant tests; write the passing run to `docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/evidence/regression-testing/pass-after.2026-07-20T21-41.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:` showing all AC-1..AC-4 regression tests passing. Acceptance: artifact records the post-fix passing run. + +### Phase 2 — Final QC Loop, Coverage & Acceptance Check-off + +- [x] [P2-T1] Run the formatter `dotnet tool run csharpier .` (or `csharpier .`) and write `docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/evidence/qa-gates/csharpier.2026-07-20T21-41.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:`. If formatting changes any file, restart the QC loop from this task. Acceptance: formatter reports a clean pass with no residual changes. +- [x] [P2-T2] Run the analyzer build `msbuild TaskMaster.sln /t:Build /p:Configuration=Debug /p:Platform="Any CPU" /p:EnableNETAnalyzers=true /p:EnforceCodeStyleInBuild=true` and write `docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/evidence/qa-gates/analyzer-build.2026-07-20T21-41.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:` (compared against the P0-T4 baseline; zero new first-party diagnostics). If the build fails or changes files, restart from P2-T1. Acceptance: no new first-party analyzer diagnostics relative to baseline. +- [x] [P2-T3] Run the nullable build `msbuild TaskMaster.sln /t:Build /p:Configuration=Debug /p:Platform="Any CPU" /p:Nullable=enable /p:TreatWarningsAsErrors=true` and write `docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/evidence/qa-gates/nullable-build.2026-07-20T21-41.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:` (first-party deltas compared against the P0-T5 baseline; vendored `SVGControl.csproj` pre-existing errors remain baseline-exempt). If the build fails on first-party code or changes files, restart from P2-T1. Acceptance: no new first-party nullable errors relative to baseline. +- [x] [P2-T4] Run the full test suite with coverage `vstest.console.exe UtilitiesCS.Test\bin\Debug\UtilitiesCS.Test.dll QuickFiler.Test\bin\Debug\QuickFiler.Test.dll /EnableCodeCoverage` (exclude any path under `.claude\worktrees\` when discovering assemblies recursively) and write `docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/evidence/qa-gates/tests-coverage.2026-07-20T21-41.md` with `Timestamp:`, `Command:`, `EXIT_CODE:`, `Output Summary:` including numeric post-change pass/fail counts and post-change line and branch coverage for the touched files. If any test fails or files change, restart from P2-T1. Acceptance: all tests pass and numeric post-change coverage is recorded. +- [x] [P2-T5] Compute and record the coverage delta to `docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/evidence/qa-gates/coverage-delta.2026-07-20T21-41.md` with `Timestamp:`, `Command:` (or derivation method), `EXIT_CODE:`, `Output Summary:` reporting baseline coverage (from P0-T6), post-change coverage (from P2-T4), and new/changed-code coverage; confirm new/changed code meets `>= 90%` and there is no regression on changed lines. If new/changed coverage is below 90% or unavailable, mark the outcome remediation-required (not PASS). Acceptance: artifact records all three numeric coverage figures and the >= 90% new-code determination. +- [x] [P2-T6] Verify AC-1 (deterministic regression reproduces the defect before the fix and passes after; no temp files / external deps / wall-clock waits) against the P1-T3 and P1-T8 evidence, then check off AC-1 in `docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/issue.md`. Acceptance: AC-1 is checked and cites the supporting evidence artifacts. +- [x] [P2-T7] Verify AC-2 (`SetSuggestionsAsync` exposes no transient cleared/partial model; row count never drops below the pre-upgrade count in flight) against the P1-T4/P2-T4 evidence, then check off AC-2 in issue.md. Acceptance: AC-2 is checked and cites the supporting evidence. +- [x] [P2-T8] Verify AC-3 (readback contract `FolderContains`/`GetSelectedFolder`/`GetFolderItems`/`SelectRow` returns pre-upgrade-consistent results in flight and the host-selected index survives the swap) against the P1-T4/P1-T7/P1-T8 evidence, then check off AC-3 in issue.md. Acceptance: AC-3 is checked and cites the supporting evidence. +- [x] [P2-T9] Verify AC-4 (completed-upgrade behavior unchanged: chains/probabilities, fallback-to-plain for unresolvable scored rows, plain non-scored rows; all existing FolderBreadcrumbBridgeRouter / BreadcrumbBridgeCoordinator / QfcItemController tests pass) against the P2-T4 evidence, then check off AC-4 in issue.md. Acceptance: AC-4 is checked and cites the supporting evidence. +- [x] [P2-T10] Verify AC-5 (full C# toolchain passes in order — csharpier, analyzer build, nullable build, vstest — with zero first-party regressions vs the Phase 0 baseline and new/changed code >= 90% coverage) against the P2-T1..P2-T5 evidence, then check off AC-5 in issue.md. Acceptance: AC-5 is checked and cites the supporting evidence.

The root cause — a +transient empty/partial window in `FolderBreadcrumbBridgeRouter.SetSuggestionsAsync` caused by a +synchronous `_model.Clear()` before the first `await` — is addressed correctly by building the upgraded +rows into a local `List` and swapping them into the model in a single call via a new +`BreadcrumbStateModel.ReplaceRows` method. `ReplaceRows` reconciles the selected index against the new +row count before publishing the replacement list, so no reader can observe a replacement list paired +with a stale out-of-range index. The change preserves the existing readback contract and the +scored/unresolvable/non-scored row-construction semantics. + +Design quality is good: the seam is small, cohesive, and well-commented with the reason (the "why") for +the atomic swap. The two blocking-for-merge items are structural/procedural rather than logic defects: +two test files exceed the 500-line limit, and the canonical HEAD coverage artifact is absent (detailed +in the policy audit).

It parses under the coverage-gate hook functions to line 86.54% and branch 80.85%, + both above the repository floors (Section 5). + +Overall verdict: PASS. No remediation-required findings remain. One procedural observation is recorded: +the regenerated coverage artifact is at a gitignored tooling-input path and will not travel with the PR; +the repo-wide floor of record for merge is the PR CI coverage run. + +## 1. Policy Reading Order Applied + +1. CLAUDE.md (all sections) +2. `.claude/rules/general-code-change.md` +3. `.claude/rules/general-unit-test.md` +4. C#: `.claude/rules/csharp.md`; CLAUDE.md C# Code Change Policy + C# Unit Test Policy; `.claude/rules/quality-tiers.md` + +## 2. Rejected Scope Narrowing + +No scope-narrowing instructions were detected in the caller prompt. The caller supplied the full branch +diff scope and explicitly delegated scope determination to this reviewer. The audit scope is the full +branch diff cd6362f0..4412d2da, not any plan, task, or phase subset. No caller instruction attempted to +mark any language as out of audit, skip a toolchain check, or limit the changed-file set. + +## 3. PR-Context Integrity Correction + +The refreshed PR-context summary overview again reported "Core logic changes: 0 files" and classified all +C# files (2 production + 5 test) as "Docs/templates/agents/tooling." This is the recurring C#-as-docs +misclassification: the automated overview lists only the top Markdown files in the hook-parsed +`- path (+N/-N)` bullet format, so the coverage-gate hook's `Get-ChangedLanguageSet` would enumerate no +language and silently skip C# coverage enforcement. The C# files were enumerated from `git diff --numstat`: + +| File | Adds/Dels | Type | +|---|---|---| +| UtilitiesCS/OutlookObjects/Folder/BreadcrumbStateModel.cs | +28/-1 | modified production | +| UtilitiesCS/OutlookObjects/Folder/FolderBreadcrumbBridgeRouter.cs | +15/-10 | modified production | +| UtilitiesCS.Test/OutlookObjects/Folder/BreadcrumbStateModelSequenceTests.cs | +235/-0 | new test (R1 split) | +| UtilitiesCS.Test/OutlookObjects/Folder/BreadcrumbStateModelTests.cs | +4/-158 | modified test (R1 split) | +| UtilitiesCS.Test/OutlookObjects/Folder/FolderBreadcrumbBridgeRouterInFlightTests.cs | +256/-0 | new test (R1 split) | +| UtilitiesCS.Test/OutlookObjects/Folder/FolderBreadcrumbBridgeRouterTests.cs | +5/-117 | modified test (R1 split) | +| QuickFiler.Test/Viewers/BreadcrumbBridgeCoordinatorTests.cs | +62/-0 | modified test | +| UtilitiesCS.Test/UtilitiesCS.Test.csproj | +2/-0 | test project (wires 2 new split files) | + +`artifacts/pr_context.summary.txt` was corrected in place (seven space-free `.cs` paths added to the +overview) so the coverage gate enumerates C# rather than skipping it. After the correction, +`Get-ChangedLanguageSet` returns `CSharp` and the gate reads the canonical artifact at 86.54% / 80.85%. +Confirmed via `git diff --diff-filter=A --name-only cd6362f0..HEAD -- '*.cs'`: the only added `.cs` files +are the two R1 split test files; no new production `.cs` file was added (the two production files are +modifications). + +## 4. Toolchain Verdicts (from executor qa-gate evidence) + +| Stage | Command (executor) | EXIT_CODE | Verdict | +|---|---|---|---| +| Format | `csharpier format .` then `csharpier check .` | 0 | PASS | +| Analyzer | `msbuild TaskMaster.sln /t:Build ... /p:EnableNETAnalyzers=true /p:EnforceCodeStyleInBuild=true` | 0 | PASS | +| Nullable | `msbuild TaskMaster.sln /t:Build ... /p:Nullable=enable /p:TreatWarningsAsErrors=true` | 0 | PASS | +| Tests | `vstest.console.exe UtilitiesCS.Test...

These verdicts rely on committed executor +evidence; they were not independently re-executed by the reviewer. The two new split test files and the +`.csproj` compile-item wiring are covered by the same 5061/5061 passing run. + +## 5. Coverage Verification (mandatory for every changed language) + +### 5.1 C# — PASS (canonical HEAD coverage artifact present; both floors met) + +- Changed C# files: 2 modified production, 6 test (Section 3). C# coverage is mandatory. +- The canonical HEAD coverage artifact at `artifacts/csharp/coverage.xml` (JaCoCo format, first-party + UtilitiesCS + QuickFiler denominator, `[ExcludeFromCodeCoverage]` honored) was regenerated during + remediation and reflects HEAD (4412d2da). Independently parsed by this reviewer via the coverage-gate + hook functions `Get-JacocoRepoCoverage` / `Get-JacocoBranchCoverage`: + - C# repo-wide line coverage: 86.54% (43143/49851) — >= 85% line floor: PASS. + - C# branch coverage: 80.85% (9331/11541) — >= 75% branch floor: PASS. +- New/changed-code line coverage: 100% (>= 90% target): PASS.

The repo-wide floor of record + at merge is the PR CI coverage run; the local canonical artifact substantiates the verdict for this + review. + +### 5.2 Other languages + +- TypeScript: no changed files in the branch diff; coverage not evaluated (no `.ts`/`.tsx` in diff). +- Python: no changed files in the branch diff; coverage not evaluated (no `.py` in diff). +- PowerShell: no changed files in the branch diff; coverage not evaluated (no `.ps1`/`.psm1` in diff). + +## 6. File-Size Limit — PASS (R1 remediation resolved) + +The R1 remediation split the two over-limit test files into cohesive, scenario-grouped files.

Evidence Location Compliance — PASS + +- All committed evidence for this feature is under + `docs/features/active/2026-07-20-breadcrumb-suggestions-upgrade-race-398/evidence//` (canonical). +- Branch-diff scan for `artifacts/baselines/`, `artifacts/qa/`, `artifacts/evidence/`, + `artifacts/coverage/`: none present (`git diff --name-only cd6362f0..HEAD | grep -E 'artifacts/(baselines|qa|evidence|coverage)/'` returned no matches). Verdict: PASS. +- `artifacts/csharp/coverage.xml` is the coverage-gate tooling-input path (gitignored), not an + evidence-output location; its presence is not an evidence-location violation. +- The repository has no `validate_evidence_locations.py` script; the scan was performed via `git diff`. + +## 8. modified-workflow-needs-green-run + +Not triggered.
