From 90e75ec19e0d0bb88e6d05168354cac4a66a6a2a Mon Sep 17 00:00:00 2001 From: Dan Moisan Date: Fri, 3 Jul 2026 16:43:56 -0400 Subject: [PATCH 1/3] fix(#232): repair QuickFiler navigation-key collision on page swap - Route LoadControlsAndHandlers_01 page-swap through SwapItemGroups so the Unregister/Register navigation pairing runs, and guard the trailing RegisterNavigation in RemoveSpecificControlGroupAsync against double registration (fixes KbdActions "Key already exists" ArgumentException) - Add additive folder-confidence probability debug logging (item summary, score, caller) at the three scoring call sites - Add QfcCollectionController regression tests for the swap and double-registration paths Refs: #232 Co-Authored-By: Claude Opus 4.8 (1M context) ---

Those are pre-existing vendored issues outside the analyzer-stack scope, not a real gate failure.

Do NOT substitute `-t:Rebuild`: a forced whole-solution Rebuild under those flags CLEANS then fails to rebuild the two vendored/exempt projects (SVGControl ~CS8603/CS0649, UtilitiesSwordfish.NET.General ~CS8625/CS8600) — 84 errors — which corrupts the Debug output state so subsequent incremental builds also try (and fail) to rebuild them. Building a single first-party .csproj with `-t:Rebuild` also drags in its vendored dependency (e.g. QuickFiler -> UtilitiesSwordfish) and fails the same way. Also note a standalone `.csproj` build needs `-p:Platform=AnyCPU` (no space); the solution maps `"Any CPU"` -> `AnyCPU` but a bare project build errors "BaseOutputPath/OutputPath not set" with the spaced form. + +**Meaningful nullable gate on a touched legacy project (the correct recipe):** the legacy first-party projects (e.g. QuickFiler) are NOT nullable-annotated and produce a large pre-existing error population when genuinely recompiled under the nullable gate (QuickFiler ~540 unique errors; `-m` parallel double-reports so `grep -c` shows ~1080). The baseline "0 errors" only means nothing recompiled. To validate a change without the vendored noise: (1) restore all outputs with a plain analyzer `-t:Build` (non-nullable, rebuilds cleaned vendored projects to 0 errors); (2) `touch` only the changed source files; (3) run the solution `-t:Build` nullable gate — MSBuild recompiles only the touched projects (their sources are newer) and leaves up-to-date vendored/other projects skipped, so their pre-existing nullable debt does not surface. To PROVE a change adds zero new nullable diagnostics, capture a controlled pre-change count: `git stash push -- `, restore outputs, touch+nullable-build, count errors; then `git stash pop`. Identical pre/post error counts with every touched-file diagnostic merely line-shifted by the inserted-line count = no-regression proof. After any Rebuild/stash dance, finish with a plain analyzer `-t:Build` to restore Debug outputs before vstest. **Pre-existing CS0618 in first-party:** UtilitiesCS/TaskMaster use obsolete IAsyncEnumerable `SelectAwait`/`WhereAwait`/`ForEachAwaitAsync` overloads (warning-only; not promoted under the analyzer `-t:Build` step which omits TWAE). An incremental baseline build may not re-emit them while a later full build does — explains baseline-vs-final warning-count deltas without any new diagnostic. diff --git a/.claude/agent-memory/task-researcher/MEMORY.md b/.claude/agent-memory/task-researcher/MEMORY.md index a3801fdaa..02ce4df54 100644 --- a/.claude/agent-memory/task-researcher/MEMORY.md +++ b/.claude/agent-memory/task-researcher/MEMORY.md @@ -4,3 +4,4 @@ - [qfc-item-controller-227-r2-denial](project_qfc_item_controller_227_r2_denial.md) — Issue #227: maintainer denied blanket exemption boundary (2026-07-01); precedent for per-member barrier analysis before any future coverage exemption - [feedback-exemption-audit-check-proven-techniques](feedback_exemption_audit_check_proven_techniques.md) — when re-auditing exemption boundaries, grep for already-proven test techniques and check sibling-method consistency before accepting IRREDUCIBLE (issue #227 cycle-2 re-audit, 2026-07-02) - [qfc227-headless-itemviewer-and-tlpcellsnapshot](project_qfc227_headless_itemviewer_and_tlpcellsnapshot.md) — Issue #227: headless ItemViewer construction confirmed safe (ProgressPane precedent); TlpCellSnapShot retrofit scoped; revised target 24 -> 19 (2026-07-02) +- [qfc-high-confidence-dual-pipeline](project_qfc_high_confidence_dual_pipeline.md) — QFC has two high-confidence filter pipelines (#169 live, #171 dead-in-prod); "subset shown" is batch-without-backfill, not a scoring bug (2026-07-03) diff --git a/.claude/agent-memory/task-researcher/project_qfc_high_confidence_dual_pipeline.md b/.claude/agent-memory/task-researcher/project_qfc_high_confidence_dual_pipeline.md new file mode 100644 index 000000000..0d87f6dff --- /dev/null +++ b/.claude/agent-memory/task-researcher/project_qfc_high_confidence_dual_pipeline.md @@ -0,0 +1,18 @@ +--- +name: qfc-high-confidence-dual-pipeline +description: QuickFiler has two independent high-confidence filter implementations (#169 post-hoc removal, live; #171 pre-filter, dead in production) plus a fixed-batch-without-backfill pattern that explains "subset of items on navigation" reports +metadata: + type: project +--- + +QuickFiler high-confidence mode has two separately-implemented filtering pipelines: +1.

Run QuickFiler in high-confidence mode with a page that has exactly one item. +2. Click the "pop out" button for that item. +3. Internally: `RemoveSpecificControlGroupAsync` unregisters the current page's key(s), removes the item (count reaches 0), and calls `QfcFormController.SkipGroupAsync()` to bring forward the next cached page via `LoadControlsAndHandlers_01(TableLayoutPanel, List)`, which swaps `_itemGroups` without calling `UnregisterNavigation()`/`RegisterNavigation()`. +4. `RemoveSpecificControlGroupAsync` then unconditionally calls `RegisterNavigation()` again for the newly swapped-in page. +5. If any key in the newly-active page's range ("1".."N") is still occupied by an orphaned entry left behind by an earlier page that was abandoned mid-page via the same defective swap path (OK or Skip while items remained), `KbdActions.Add` throws `ArgumentException`. + +## Expected Behavior + +Keyboard digit-navigation keys ("1".."N", `SourceId = "Collection"`) always match exactly the currently-displayed page's items, regardless of whether the page changed via individual item removal, "OK" (move + load next), or "Skip". No stale keys should ever remain registered for a page that is no longer displayed. + +## Actual Behavior + +`QfcCollectionController.LoadControlsAndHandlers_01(TableLayoutPanel, List)` (`QuickFiler/Controllers/QfcCollectionController.cs:252-262`) — the swap-in path used by both the "OK" flow (`QfcFormController.EventHandlers.cs:136-143`) and the "Skip" flow (`QfcFormController.EventHandlers.cs:361-395`, also invoked internally from `RemoveSpecificControlGroupAsync`'s zero-item branch) — never calls `UnregisterNavigation()` for the outgoing page or `RegisterNavigation()`/`WireUpAsyncKeyboardHandler()` for the incoming page. Its unused sibling `SwapItemGroups` (line 870-878) shows the correct pattern. `_kbdHandler.StringActionsAsync` is a single, session-lifetime collection shared across all pages, so keys orphaned by this gap collide the next time `RegisterNavigation()` walks from position 0 — which happens unconditionally at the end of `RemoveSpecificControlGroupAsync` (line 1219). + +## Logs / Screenshots + +- [x] Attached minimal logs or screenshot +- Snippet: +``` +System.ArgumentException + HResult=0x80070057 + Message=Cannot add key because it already exists.

Confirmed root cause: missing `UnregisterNavigation()`/`RegisterNavigation()` pairing in `LoadControlsAndHandlers_01(TableLayoutPanel, List)`, `QuickFiler/Controllers/QfcCollectionController.cs:252-262`. Copilot's initial "overlapping `RemoveSpecificControlGroupAsync` race" hypothesis was investigated and ruled out as the primary explanation — this is a deterministic sequencing/bookkeeping gap, not a race. Recommended fix: route the swap through the existing (currently dead) `SwapItemGroups` method, which already does `UnregisterNavigation(); ...; RegisterNavigation();` correctly, and decide whether the trailing unconditional `RegisterNavigation()` in `RemoveSpecificControlGroupAsync` (line 1219) needs to become conditional to avoid double-registration once the swap path registers correctly on its own. + +**Bundled scope (user-requested, same change):** Add `logger.Debug(...)` calls at every point a folder-confidence probability is computed, each capturing item summary (Subject/EntryID), the computed score, and a literal caller-context string, per the existing log4net convention already used throughout this file family.

Key 2 SourceId Collection` when a page transition (OK/Skip, including the automatic skip triggered by popping out the last item on a page) swaps in a new page without unregistering the outgoing page's keyboard navigation keys or registering the incoming page's keys, leaving stale `"Collection"`-sourced keys in the shared `KbdActions` registry that later collide. Bundled with this fix, at the user's request, is an additive debug-logging change so that every folder-confidence probability calculation is logged (item summary, score, caller) to make a separately-observed "only a subset of items appears in high-confidence mode" symptom empirically diagnosable in future sessions. + +Environment: +- OS/version: Windows (VSTO Outlook add-in host) +- Repo/branch: TaskMaster, branch `TaskMaster-wt-2026-07-03-10-11`, HEAD `00507b59` +- Command/flags used: QuickFiler run in "high confidence mode" +- Data source or fixture: Live Outlook inbox (production run, not a test fixture) + +Impact / Severity: +- [x] High +- [ ] Blocker +- [ ] Medium +- [ ] Low + +Rationale: crashes the active QuickFiler session (unhandled exception surfaced to the user) during ordinary bulk-processing use; reachable via everyday OK/Skip page transitions, not an edge case. + + +## Repro & Evidence +Steps to Reproduce: +1. Run QuickFiler in high-confidence mode with a page that has exactly one item. +2. Click the "pop out" button for that item. +3. Internally: `RemoveSpecificControlGroupAsync` unregisters the current page's key(s), removes the item (count reaches 0), and calls `QfcFormController.SkipGroupAsync()` to bring forward the next cached page via `LoadControlsAndHandlers_01(TableLayoutPanel, List)`, which swaps `_itemGroups` without calling `UnregisterNavigation()`/`RegisterNavigation()`. +4. `RemoveSpecificControlGroupAsync` then unconditionally calls `RegisterNavigation()` again for the newly swapped-in page. +5. If any key in the newly-active page's range ("1".."N") is still occupied by an orphaned entry left behind by an earlier page that was abandoned mid-page via the same defective swap path (OK or Skip while items remained), `KbdActions.Add` throws `ArgumentException`. + +Expected: +Keyboard digit-navigation keys ("1".."N", `SourceId = "Collection"`) always match exactly the currently-displayed page's items, regardless of whether the page changed via individual item removal, "OK" (move + load next), or "Skip". No stale keys should ever remain registered for a page that is no longer displayed. + +Actual: +`QfcCollectionController.LoadControlsAndHandlers_01(TableLayoutPanel, List)` (`QuickFiler/Controllers/QfcCollectionController.cs:252-262`) — the swap-in path used by both the "OK" flow (`QfcFormController.EventHandlers.cs:136-143`) and the "Skip" flow (`QfcFormController.EventHandlers.cs:361-395`, also invoked internally from `RemoveSpecificControlGroupAsync`'s zero-item branch) — never calls `UnregisterNavigation()` for the outgoing page or `RegisterNavigation()`/`WireUpAsyncKeyboardHandler()` for the incoming page. Its unused sibling `SwapItemGroups` (line 870-878) shows the correct pattern. `_kbdHandler.StringActionsAsync` is a single, session-lifetime collection shared across all pages, so keys orphaned by this gap collide the next time `RegisterNavigation()` walks from position 0 — which happens unconditionally at the end of `RemoveSpecificControlGroupAsync` (line 1219). + +Logs / Screenshots: +- [x] Attached minimal logs or screenshot +- Snippet: +``` +System.ArgumentException + HResult=0x80070057 + Message=Cannot add key because it already exists.

Confirmed root cause: missing `UnregisterNavigation()`/`RegisterNavigation()` pairing in `LoadControlsAndHandlers_01(TableLayoutPanel, List)`, `QuickFiler/Controllers/QfcCollectionController.cs:252-262`. Copilot's initial "overlapping `RemoveSpecificControlGroupAsync` race" hypothesis was investigated and ruled out as the primary explanation — this is a deterministic sequencing/bookkeeping gap, not a race. Recommended fix: route the swap through the existing (currently dead) `SwapItemGroups` method, which already does `UnregisterNavigation(); ...; RegisterNavigation();` correctly, and decide whether the trailing unconditional `RegisterNavigation()` in `RemoveSpecificControlGroupAsync` (line 1219) needs to become conditional to avoid double-registration once the swap path registers correctly on its own. + +**Bundled scope (user-requested, same change):** Add `logger.Debug(...)` calls at every point a folder-confidence probability is computed, each capturing item summary (Subject/EntryID), the computed score, and a literal caller-context string, per the existing log4net convention already used throughout this file family.

Research concluded the subset symptom is most likely explained by an existing fixed-batch-without-backfill pattern (not a threshold bug, and not proven to be caused by score mutation across time) — see Investigation 2 in the research artifact. Fixing that batch/backfill behavior, or wiring up the currently-dead Issue #171 pre-filter pipeline, are explicitly **not** part of this change; they are flagged as separate candidate follow-up issues. + + +## Proposed Fix + +### Design summary (what changes where): +Two independent, non-overlapping changes bundled into one PR: +1. **Navigation-key fix** (`QfcCollectionController.cs`): make `LoadControlsAndHandlers_01(TableLayoutPanel, List)` unregister the outgoing page's keys and register the incoming page's keys during the swap, by delegating the item-groups swap portion to the existing `SwapItemGroups(List)` method (which already implements `UnregisterNavigation(); ...; RegisterNavigation();` correctly) instead of calling `ActivateQueuedItemGroups(itemGroups)` directly. Then re-examine `RemoveSpecificControlGroupAsync`'s trailing, unconditional `RegisterNavigation()` (line ~1219): once the zero-item branch's `SkipGroupAsync()` call performs a correct register via the fixed swap path, the trailing call would attempt to re-register the same page's keys a second time in the same call stack and must be skipped in that specific branch (guard on whether a swap-and-register already occurred during this invocation). +2. **Probability debug logging** (`QfcDatamodel.cs`, `QfcItemController.FolderHandling.cs`, `QfcHighConfidencePreFilter.cs`): add `logger.Debug(...)` immediately after each of the three identified score-computation points, with no control-flow change. + +### Boundaries and invariants to preserve: +- `_kbdHandler.StringActionsAsync` must, after any page transition, contain exactly one `"Collection"`-sourced entry per key `"1".."N"` (or zero-padded per current `Digits`) matching the live `_itemGroups`, and zero entries for any page no longer displayed. +- `KbdActions.Add`'s existing throw-on-duplicate contract is preserved unchanged (Approach B, making it idempotent, is rejected). +- `SwapItemGroups`'s existing signature and behavior are preserved; it is invoked from a new call site, not modified. +- The public surface of `LoadControlsAndHandlers_01(TableLayoutPanel, List)` (signature, callers) is unchanged. +- Probability logging is purely additive: no return values, thresholds, or control flow may change as a result of adding the log calls. + +### Dependencies or blocked work: +None. Both changes are self-contained within `QuickFiler/Controllers/`. + +### Implementation strategy (what changes, not sequencing): + +#### Files/modules to change: +1. `QuickFiler/Controllers/QfcCollectionController.cs` — navigation-key fix (route swap through `SwapItemGroups`; guard the trailing `RegisterNavigation()` in `RemoveSpecificControlGroupAsync` against double-registration after a swap-triggered registration). +2. `QuickFiler/Controllers/QfcDatamodel.cs` — add debug log after score computation in `ScoreRemainingQueueMailItemAsync` (lines ~316-326). +3. `QuickFiler/Controllers/QfcItemController.FolderHandling.cs` — add debug log after each of the 4 `_folderHandler = ...` assignment points in `LoadFolderHandler`/`LoadFolderHandlerAsync` (lines ~27-111). +4. `QuickFiler/Controllers/QfcHighConfidencePreFilter.cs` — add a new `logger` field and a debug log inside the `FilterAsync` per-item lambda (lines ~62-70). + +Corresponding test files (existing `QuickFiler.Test` project, MSTest/Moq/FluentAssertions per repo policy): +- `QuickFiler.Test/Controllers/QfcFormControllerTests.cs` (or a new sibling test file if the existing one is at/near the 500-line cap) — add/extend mock-based assertions for register/unregister ordering on page swap. +- A new or extended `QfcCollectionController`-focused test (seam-permitting) reproducing the exact reported scenario. + +#### Functions/classes/CLI commands impacted: +- `QfcCollectionController.LoadControlsAndHandlers_01(TableLayoutPanel, List)` +- `QfcCollectionController.RemoveSpecificControlGroupAsync(int selection)` +- `QfcCollectionController.SwapItemGroups(List)` (new caller, no signature change) +- `QfcDatamodel.ScoreRemainingQueueMailItemAsync(MailItem, CancellationToken)` +- `QfcItemController.LoadFolderHandler(object)` / `LoadFolderHandlerAsync(CancellationToken, object)` +- `QfcHighConfidencePreFilter.FilterAsync(...)` + +No CLI commands are impacted (WinForms/VSTO add-in, no CLI surface). + +#### Data flow and validation changes: +No data-flow or validation-rule changes. The navigation-key fix corrects internal bookkeeping (a collection membership invariant); the logging change reads already-computed values without altering them. + +#### Error handling and logging updates: +- Navigation-key fix removes the reachability of the reported `ArgumentException` for the documented scenario; no new exception types are introduced. +- New `logger.Debug(...)` calls at 3 call sites (4 assignment points in one of them) per the Suspected Cause / Notes section above, following the existing `private static readonly log4net.ILog logger = log4net.LogManager.GetLogger(...)` convention already present in `QfcDatamodel.cs`/`QfcItemController.cs` and newly added to `QfcHighConfidencePreFilter.cs`. + +#### Rollback/feature-flag considerations (if applicable): +None required — both changes are behavior-preserving except for the specific defect being corrected (no feature flag; a straight revert of the commit(s) fully rolls back). + +### Technical specifications (interfaces/contracts): + +#### Inputs/outputs and formats: +No public interface/contract changes. Log message format: include item summary (Subject and/or EntryID), the numeric score, and a literal caller-context string identifying the invoking method/branch (per convention documented in the research artifact, Investigation 2 §2.2). + +#### Required configuration keys and defaults: +None new. Debug-level visibility is controlled entirely by the existing `log4net.config` root logger level (``); no new config key is introduced. + +#### Backward-compatibility expectations: +Fully backward compatible — no public API signatures change, no persisted data formats change, no configuration schema changes. + +#### Performance constraints (latency/throughput/memory): +Negligible: one additional string-formatted debug log call per item per scoring call site (bounded by page size / inbox batch size, consistent with existing `logger.Debug` calls already present in this file family); no additional COM round-trips introduced (reuses already-loaded `Subject`/`EntryID` values per the research artifact's convention citation). + +## Assumptions, Constraints, Dependencies +- Assumptions (environment, data, access): the shared `_kbdHandler.StringActionsAsync` collection remains a single, session-lifetime instance per the confirmed research finding (`KeyboardHandler.cs:84-89`); no other in-flight change re-architects keyboard-handler ownership. +- Constraints (budget, performance, compatibility): repo file-size cap (500 lines) applies to any modified/new test file; no live-Outlook dependency may be introduced in tests; MSTest + Moq + FluentAssertions only. +- External dependencies (services, libraries, releases): none. No new package dependencies. + +## Data / API / Config Impact +- User-facing or API changes: none (internal bookkeeping fix; logging is developer/diagnostic-facing only, gated by existing log4net config, not user-visible UI). +- Data or migration considerations: none. +- Logging/telemetry updates (if any): 3 new `logger.Debug(...)` call sites (4 assignment points in one of them) per Proposed Fix above; no telemetry system changes. +- Compatibility notes (CLI flags, config schemas, versioning): none (no CLI surface; no config schema changes). + +## Test Strategy +Seeded from issue: + +- [x] Unit coverage areas: `QfcFormControllerTests.cs`-style mock-based assertions that `LoadItems(TableLayoutPanel, List)` invokes `RegisterNavigation()`/`UnregisterNavigation()` in the correct order; a logical-level regression test reproducing the exact reported scenario (1-item page popped out, cached ≥2-item page swapped in, no `ArgumentException` on the subsequent `RegisterNavigation()`); no dedicated new tests required for the additive `logger.Debug` calls beyond confirming they do not throw. +- [ ] Integration scenario to retest: manual QuickFiler high-confidence-mode run exercising OK, Skip, and single-item pop-out transitions across multiple pages. +- [ ] Manual verification notes: after the fix, confirm `_kbdHandler.StringActionsAsync` never accumulates stale entries across a full multi-page processing session. + +- Regression tests to add or update: new MSTest test(s) in `QuickFiler.Test/Controllers/` reproducing (a) register/unregister ordering on `LoadItems`/`LoadControlsAndHandlers_01` swap via the existing `IQfcCollectionController` mock pattern, and (b) the exact reported crash scenario at whatever seam is feasible per the coverage-exemption carve-out for testable seams within COM-bound classes. +- Unit tests (MSTest/Moq/FluentAssertions) for the fixed behavior and boundaries: positive (swap registers/unregisters correctly), negative (pre-fix reproduction would throw; post-fix must not), edge (page size 1 → 0 transition, page size crossing the 9/10-item digit-format boundary if reachable within the fix's scope). +- Edge cases and negative scenarios (invalid inputs, missing data, boundary values): zero-item outgoing page (no keys to unregister — must remain a no-op, not an error); incoming cached page with 0 items (no keys to register); digit-format boundary (1 → 2 digits) during a swap. +- Error handling and logging verification: confirm no `ArgumentException` is thrown for the documented scenario; confirm new debug log calls do not throw when their referenced fields (`ItemHelper`, `_folderHandler`, `mailItem`) are in normal post-assignment state. +- Coverage impact and targets for changed lines/modules: `QfcCollectionController.cs` is `[ExcludeFromCodeCoverage]` (ratified COM/WinForms exemption) — no numeric coverage obligation on that file's changed lines, but behavioral verification via the mock-based test pattern is still required per Test Strategy above. `QfcDatamodel.cs` and `QfcItemController.FolderHandling.cs` are within the same ratified exemption. `QfcHighConfidencePreFilter.cs` is NOT exempt — its existing `QfcHighConfidencePreFilterTests.cs` scoring-seam mock must continue to exercise the new log line without a coverage regression. +- Toolchain commands to run (format → lint → type-check → test): `dotnet tool run csharpier .` → `msbuild TaskMaster.sln /t:Build /p:Configuration=Debug /p:Platform="Any CPU" /p:EnableNETAnalyzers=true /p:EnforceCodeStyleInBuild=true` → `msbuild TaskMaster.sln /t:Build /p:Configuration=Debug /p:Platform="Any CPU" /p:Nullable=enable /p:TreatWarningsAsErrors=true` → `vstest.console.exe /EnableCodeCoverage`. +- Manual validation steps (if required): manual QuickFiler high-confidence-mode session exercising OK, Skip, and single-item pop-out transitions across multiple pages, confirming no `ArgumentException` and confirming new debug log lines appear per item scored. + +## Acceptance Criteria +- [x] AC1: `LoadControlsAndHandlers_01(TableLayoutPanel, List)` unregisters the outgoing page's `"Collection"` navigation keys and registers the incoming page's navigation keys on every swap (verified via mock-based assertion on `RegisterNavigation()`/`UnregisterNavigation()` call order). — Evidence: P3-T1/P3-T2, `evidence/regression-testing/swap-register-unregister-order.pass.md`. +- [x] AC2: The reported reproduction (1-item page popped out; `RemoveSpecificControlGroupAsync` reaches zero items; `SkipGroupAsync` swaps in a cached page whose key range overlaps a previously-abandoned page's stale keys) no longer throws `ArgumentException`; a regression test encodes this exact scenario and passes. — Evidence: P1-T2 (expect-fail) `evidence/regression-testing/reported-repro.expect-fail.md`, P2-T3 `evidence/regression-testing/reported-repro.pass-after-fix.md`. +- [x] AC3: `RemoveSpecificControlGroupAsync`'s trailing `RegisterNavigation()` does not double-register keys already registered by a swap that occurred earlier in the same call (no `ArgumentException` from re-adding the same key twice within one invocation). — Evidence: P2-T2 guard fix; P3-T3/P3-T4/P3-T5 `evidence/regression-testing/double-registration-guard.pass.md`. +- [x] AC4: `QfcDatamodel.ScoreRemainingQueueMailItemAsync` logs at debug level, for every item scored, the item summary (Subject/EntryID), the computed score, and a caller-context string. — Evidence: P4-T1 (`QfcDatamodel.cs` `logger.Debug` in `ScoreRemainingQueueMailItemAsync`); verified by P4-T6 `evidence/regression-testing/part-b-logging-no-regression.md`. +- [x] AC5: `QfcItemController.LoadFolderHandler`/`LoadFolderHandlerAsync` log at debug level, at all 4 assignment points, the item summary, computed score, and a caller-context string distinguishing the branch. — Evidence: P4-T2/P4-T3 (four `logger.Debug` calls with FromField/FromArrayOrString caller-context strings in `QfcItemController.FolderHandling.cs`); verified by P4-T6 `evidence/regression-testing/part-b-logging-no-regression.md`. +- [x] AC6: `QfcHighConfidencePreFilter.FilterAsync` logs at debug level, for every item scored, the item summary, computed score, and topFolder, and a caller-context string; a new `logger` field is added to this file following repo log4net convention. — Evidence: P4-T4 (new `logger` field) and P4-T5 (`logger.Debug` in the `FilterAsync` scoring lambda logging Subject/EntryID/Score/TopFolder); verified by P4-T6 `evidence/regression-testing/part-b-logging-no-regression.md`. +- [x] AC7: The logging additions introduce no behavior change — all pre-existing tests covering `ScoreRemainingQueueMailItemAsync`, `LoadFolderHandler(Async)`, and `QfcHighConfidencePreFilterTests.cs` continue to pass unmodified. — Evidence: P4-T6 `evidence/regression-testing/part-b-logging-no-regression.md` (29/29 tests pass across the three unmodified test files; no assertions altered). +- [x] AC8: No unintended behavior changes outside the defined scope (fixed-batch-without-backfill pattern, dormant #171 pre-filter, and `removespecificcontrolgroupcounter` reentrancy hygiene remain untouched and are documented as follow-up). — Evidence: P3-T6 `evidence/other/ac8-scope-confirmation.md`; follow-ups recorded in P6-T4 `evidence/other/follow-up-candidates.md`. +- [x] AC9: Full C# toolchain (csharpier → .NET analyzers → nullable/TreatWarningsAsErrors → MSTest via vstest.console.exe) passes with no regressions, in this exact order, in a single clean pass. — Evidence: P5-T1 `evidence/qa-gates/csharpier-final.md` (0 files changed), P5-T2 `evidence/qa-gates/msbuild-analyzers-final.md` (0 errors, no new diagnostics), P5-T3 `evidence/qa-gates/msbuild-nullable-final.md` (zero new nullable diagnostics;

(2) `QfcCollectionController` is COM/WinForms-bound and coverage-exempt, so behavioral verification depends on the `IQfcCollectionController` mock seam rather than direct coverage — mitigate by also adding a direct-seam test if one is feasible per the "testable seams within otherwise-COM-bound assemblies are not exempt" policy carve-out (research artifact §8). (3) Adding a `logger` field to `QfcHighConfidencePreFilter.cs` for a currently-dead-in-production code path has low risk but should not be mistaken for wiring up Issue #171 — explicitly out of scope. +- Mitigations and rollbacks: both changes are behavior-preserving except for the targeted defect; a straight `git revert` of the change fully rolls back with no data/schema/config cleanup required. + +## Rollout & Follow-up +- Release/rollout steps: standard PR merge to `main`; no phased rollout, feature flag, or data migration required. +- Post-fix monitoring or clean-up tasks: candidate follow-up issues (not part of this change) — (1) fixed-batch-without-backfill pattern in `QfcDatamodel.InitEmailQueue`/`DequeueNextItemGroupAsync` causing "subset of items shown" in high-confidence mode; (2) dormant Issue #171 pre-filter pipeline never wired into the live startup path; (3) `removespecificcontrolgroupcounter` reentrancy-counter hygiene (leaks upward on any exception mid-method, unsynchronized outside the `Interlocked` calls themselves). +- Links: Issue #232 (`https://github.com/drmoisan/TaskMaster/issues/232`); research artifact `artifacts/research/2026-07-03T00-00-quickfiler-kbdactions-duplicate-key-research.md`.

Part A fixes a `System.ArgumentException: Cannot add key because it already exists. Key 2 SourceId Collection` that crashed active QuickFiler sessions on page transitions: `LoadControlsAndHandlers_01(TableLayoutPanel, List)` previously called `ActivateQueuedItemGroups` directly, swapping in a new page without unregistering the outgoing page's `"Collection"` navigation keys or registering the incoming page's keys, leaving stale entries in the session-lifetime `KbdActions` registry that later collided. The fix routes the swap through the existing (previously dead) `SwapItemGroups` method — which already unregisters then re-registers correctly — and guards the trailing unconditional `RegisterNavigation()` in `RemoveSpecificControlGroupAsync` with a method-local `bool` so the zero-item skip path does not double-register. Part B adds seven additive `logger.Debug(...)` calls across three folder-confidence scoring sites plus a new `logger` field in `QfcHighConfidencePreFilter.cs`, with no control-flow change. + +**What changed:** 4 C# production files (`QfcCollectionController.cs` +13 net; `QfcDatamodel.cs` +4; `QfcHighConfidencePreFilter.cs` +9; `QfcItemController.FolderHandling.cs` +20) and 1 test file (`QfcCollectionControllerTests.cs` +172, four new MSTest regression tests). The remaining diff is feature-folder docs, evidence artifacts, and task-researcher memory markdown. The larger dequeue-time high-confidence rework is intentionally excluded and tracked as feature #233. + +**Top 3 risks:** +1. Machine-readable coverage artifact for C# is absent; the 100%-changed-line and no-regression claims exist only as prose transcription and cannot be independently verified from an artifact (blocking; see policy audit and remediation inputs). +2. The guard `swapAlreadyRegistered` correctly suppresses the trailing register only on the zero-item skip branch; an incorrect guard could silently leave the incoming page unregistered. The behavior is asserted by the new tests, mitigating this. +3. `QfcCollectionController.cs` is COM/WinForms coverage-exempt, so Part A behavior is verified through a `GetUninitializedObject` + reflection-injected seam rather than direct coverage; the seam is unusual but deterministic. + +**PR readiness recommendation:** **Conditional Go** — implementation quality supports merge; the one blocking item is the missing C# coverage artifact, which is an evidence/verification gap rather than a code defect. + +--- + +## Findings Table + +| Severity | File | Location | Finding | Recommendation | Rationale | Evidence | +|---|---|---|---|---|---|---| +| Blocker | `docs/features/active/2026-07-03-quickfiler-navigation-key-collision-232/evidence/qa-gates/` | coverage evidence | Machine-readable C# Cobertura coverage artifact absent; coverage exists only as transcribed prose. | Regenerate the Cobertura coverage run and persist the XML at `artifacts/csharp/coverage.xml` or `.../evidence/coverage/`; re-verify claims. | Coverage Verification model requires inspecting a coverage artifact for every changed language; fail-closed. | `find . -name coverage.xml` returns only feature #177 files; `artifacts/csharp/` does not exist. | +| Minor | `QuickFiler/Controllers/QfcDatamodel.cs` | ~325 | Log caller-context string reads `[QfcDatamodel.LoadRemainingEmailsToQueueAsync (master-queue admission)]`, but the `logger.Debug` physically sits in `ScoreRemainingQueueMailItemAsync` (the method named by spec AC4). | Optionally align the context label to the enclosing method, or keep and document that it names the logical caller flow. | Diagnostic string names a different method than the one it is in; could mislead a future log reader. AC4 requires "a caller-context string," which is present. | `git show HEAD:QfcDatamodel.cs` lines 316–329. | +| Minor | `QuickFiler.Test/Controllers/QfcCollectionControllerTests.cs` | whole file | File is now exactly 500 lines — at the policy cap. | Split future `QfcCollectionController` tests into a sibling file. | Any further addition breaches the 500-line limit. | `awk END{print NR}` = 500. | +| Info | `QuickFiler/Controllers/QfcCollectionController.cs` | whole file | Pre-existing 2308-line file (> 500-line limit); this change adds +13 net lines. | No action for this bug fix; consider a separate refactor issue. | Pre-existing legacy COM-bound controller; not introduced by #232. | `git show HEAD:...` = 2308 lines. | +| Info | `QuickFiler.Test/Controllers/QfcCollectionControllerTests.cs` | `LoadControlsAndHandlers_01_ReportedRepro_...ThrowsBeforeFix` | Test asserts the swap *throws* `ArgumentException` (with a seeded orphan key) to prove registration now occurs during the swap — a valid but non-obvious inversion of the "no longer throws" AC2 framing. | None required; the XML-doc already explains the construction. | Naming/semantics could confuse; documentation mitigates. | Test docstring + body. | + +No unresolved Major findings. + +--- + +## Implementation Audit + +### C# implementation audit + +#### What changed well + +- **Reuse over duplication (Part A).** The fix delegates the swap to the existing, correct `SwapItemGroups(List)` rather than re-implementing unregister/register logic at the call site. This eliminates the divergence between the defective `ActivateQueuedItemGroups`-only path and the already-correct sibling method, aligning with the repository's simplicity-first and reusability principles. +- **Minimal, targeted guard.** The double-registration hazard is addressed with a single method-scoped `bool swapAlreadyRegistered`, set only on the zero-item skip branch and checked immediately before the trailing `RegisterNavigation()`. This is the smallest change that preserves the existing control flow while removing the reachable collision. +- **Rationale comments.** Both Part A edits carry `why`-focused comments citing Issue #232, explaining the stale-key mechanism and the double-registration guard — appropriate for a non-obvious bookkeeping fix. +- **Purely additive logging (Part B).** All seven log calls are appended after already-computed values; no return value, threshold, or branch is altered. The new `logger` field in `QfcHighConfidencePreFilter.cs` follows the established `log4net.LogManager.GetLogger(...DeclaringType)` pattern used elsewhere in the file family. + +#### Type safety and API notes + +- No public API surface changed: `LoadControlsAndHandlers_01`, `SwapItemGroups`, and `RemoveSpecificControlGroupAsync` signatures and callers are unchanged. +- Log interpolation uses null-conditional access (`ItemHelper?.Subject`, `_folderHandler?.Suggestions?.TopScore() ?? 0`, `mailItem.Subject`), consistent with the codebase and nullable-safe. The nullable forced-recompile shows zero new diagnostics. +- The `KbdActions.Add` throw-on-duplicate contract is preserved unchanged; the fix removes the reachable duplicate rather than masking it (the rejected Approach B). + +#### Error handling and logging + +- The fix does not introduce or catch new exception types; it removes the reachability of the reported `ArgumentException` for the documented scenario. +- Debug logging is gated by the existing log4net root level; no new configuration key. Log volume is one line per item per scoring site, bounded by page/batch size and consistent with pre-existing `logger.Debug` usage. +- The `removespecificcontrolgroupcounter` reentrancy-counter hygiene issue is intentionally left unchanged (documented follow-up); the guard uses a separate local and does not perturb the counter. + +--- + +## Test Quality Audit + +The four new Part A tests are deterministic and hermetic: they construct an uninitialized controller via `FormatterServices.GetUninitializedObject`, inject a real in-memory `KbdActions` behind a Loose `IQfcKeyboardHandler`, and force `IQfcFormViewer.L1v0L2L3v_TableLayout` to null to avoid WinForms-bound paths. `_digits = 1` is deliberately set to bypass the `SetVisualDigits` WinForms path — a documented, understood workaround for the seam. Part B is verified as behavior-preserving by running the 29 pre-existing tests over the three affected files with no assertion changes (AC7). + +### Reviewed test and QA artifacts + +- `QuickFiler.Test/Controllers/QfcCollectionControllerTests.cs` — 4 new tests covering register/unregister ordering, duplicate-key throw, and guarded-skip final state; mock-based, no I/O. +- `evidence/regression-testing/reported-repro.expect-fail.md` / `reported-repro.pass-after-fix.md` — the reported-repro boundary before/after the fix. +- `evidence/regression-testing/swap-register-unregister-order.pass.md` — AC1 ordering assertion. +- `evidence/regression-testing/double-registration-guard.pass.md` — AC3 guard behavior. +- `evidence/regression-testing/part-b-logging-no-regression.md` — 29/29 pre-existing tests pass over the Part B call sites. +- `evidence/qa-gates/vstest-final.md` — 4641/4641 pass; repo-wide 76.5712%; `QfcHighConfidencePreFilter.cs` 100% (transcribed). +- `evidence/qa-gates/coverage-delta.md` — baseline→final coverage comparison (transcribed; underlying XML not persisted — see Findings/Blocker). + +### Quality assessment prompts + +- **Determinism:** No randomness, time, network, filesystem, or COM; Moq + in-memory registry. +- **Isolation:** Each test targets a single behavior with fresh instances. +- **Speed:** Full suite 52.88s; Part B subset 1.29s. +- **Diagnostics:** FluentAssertions with message matchers (`*Key 2 SourceId Collection*`) and precise count assertions. + +--- + +## Security / Correctness Checks + +| Check | Status | Evidence | +|---|---|---| +| No secrets in code | ✅ PASS | Diff contains only control-flow fix and debug logging of Subject/EntryID/Score; no credentials. | +| No unsafe subprocess or command construction | ✅ PASS | No process/shell invocation in the change. | +| Input validation at boundaries | ✅ PASS | Registry-membership invariant enforced by the swap; null-conditional access in log calls. | +| Error handling remains explicit | ✅ PASS | Throw-on-duplicate contract preserved; reachable collision removed, not swallowed. | +| Configuration / path handling is safe | N/A | No config or path handling changed. | +| Diagnostic logging does not leak sensitive data beyond existing convention | ⚠️ PARTIAL | Debug logs include mail Subject/EntryID, consistent with existing `logger.Debug` usage in this file family; gated by log4net level. Acceptable per established convention, worth noting for privacy-sensitive deployments. | + +--- + +## Research Log + +No external research was required. The review is grounded in the branch diff (`git diff 00507b59..90e75ec1`), the feature-folder `spec.md`/`issue.md`, the five `evidence/qa-gates/*` and four `evidence/regression-testing/*` artifacts, and direct file-line inspection of the four changed C# files and the test file. + +--- + +## Verdict + +The implementation is correct, minimally scoped, and well-evidenced. Part A removes the reachable `ArgumentException` by reusing the already-correct `SwapItemGroups` and guarding the trailing register; Part B is strictly additive logging with no behavioral impact, confirmed by 29 unchanged passing tests. Format, analyzer, and test gates are clean; the nullable gate's non-zero exit is a pre-existing legacy-project condition with a proven zero-delta error population. + +The change is **Conditional Go**: the sole blocking item is the absent machine-readable C# coverage artifact, an evidence-verification gap rather than a code defect. Regenerate and persist the Cobertura coverage XML and re-verify the transcribed coverage claims, after which this change is ready for normal PR flow. This conclusion is consistent with the Findings Table and the PR readiness recommendation above. diff --git

The branch delivers two bundled, non-overlapping C# changes: (Part A) a navigation-key duplicate-registration crash fix in `QfcCollectionController.cs` with four new MSTest regression tests, and (Part B) additive folder-confidence probability debug logging across three controller files. The excluded larger dequeue-time high-confidence rework (feature #233) is out of scope by design and confirmed untouched. + +Implementation quality is high and scope discipline is well-evidenced. The three non-coverage toolchain gates (csharpier, .NET analyzers, MSTest) pass cleanly with no new diagnostics; the nullable gate exits non-zero solely due to pre-existing legacy VSTO nullable debt, with a documented byte-identical before/after error population proving zero new nullable diagnostics. The four regression tests are deterministic, isolated, and mock-based (no live-Outlook/COM dependency, no temp files). + +**One blocking finding:** the mandatory machine-readable C# coverage artifact is absent. No `artifacts/csharp/coverage.xml` exists, and no Cobertura XML was persisted anywhere under the Issue #232 evidence tree; the coverage evidence exists only as transcribed prose numbers in `vstest-baseline.md`, `vstest-final.md`, and `coverage-delta.md`. The Coverage Verification model in the feature-review contract requires inspecting a machine-readable coverage artifact for every language with changed files; its absence is a fail-closed condition and a remediation trigger. The substantive transcribed figures (non-exempt `QfcHighConfidencePreFilter.cs` changed lines 100% >= 90%; repo-wide flat at ~76.57%) are internally consistent and, if the artifact is regenerated, are expected to support the coverage claims — but they cannot be independently verified from an artifact as required. + +**Policy documents evaluated:** +- ✅ `CLAUDE.md` (all sections; C# Code Change Policy, General/C# Unit Test Policy, COM/VSTO/WinForms coverage exemption) +- ✅ `.claude/rules/general-code-change.md` +- ✅ `.claude/rules/general-unit-test.md` +- ✅ `.claude/rules/csharp.md` (via CLAUDE.md embedded C# policy) + +**Language-specific policies evaluated:** +- N/A `python-*` (no Python files changed) +- N/A `powershell-*` (no PowerShell files changed) +- N/A Bash / JSON (no such files changed) +- ✅ C# Code Change Policy + C# Unit Test Policy (MSTest/Moq/FluentAssertions) + +**Temporary artifacts cleanup:** +- ✅ No temporary/one-time scripts were created by this review (review is check-only, no mutation of source or policy). +- N/A No ongoing tooling scripts were added by the change. + +--- + +## 1.

No shared mutable static state; the shared registry is per-test. | +| **Isolation** - Each test targets single behavior | ✅ PASS | Each `[TestMethod]` targets one behavior: reported-repro registration boundary, swap add/remove, duplicate-register throw, guarded-skip final state. | +| **Fast Execution** - Tests complete quickly | ✅ PASS | Full suite 4641 tests in 52.88s (`vstest-final.md`); the Part B subset ran 29 tests in 1.29s. New tests are pure in-memory. | +| **Determinism** - Consistent results | ✅ PASS | No randomness, time, or I/O; Moq `Loose` mocks and an in-memory `KbdActions`.

(2) `QfcCollectionController` is COM/WinForms-bound and coverage-exempt, so behavioral verification depends on the `IQfcCollectionController` mock seam rather than direct coverage — mitigate by also adding a direct-seam test if one is feasible per the "testable seams within otherwise-COM-bound assemblies are not exempt" policy carve-out (research artifact §8). (3) Adding a `logger` field to `QfcHighConfidencePreFilter.cs` for a currently-dead-in-production code path has low risk but should not be mistaken for wiring up Issue #171 — explicitly out of scope.

The branch delivers two bundled, non-overlapping C# changes. Part A fixes a `System.ArgumentException: Cannot add key because it already exists. Key 2 SourceId Collection` that crashed active QuickFiler sessions on page transitions: `LoadControlsAndHandlers_01(TableLayoutPanel, List)` previously called `ActivateQueuedItemGroups` directly, swapping in a new page without unregistering the outgoing page's `"Collection"` navigation keys or registering the incoming page's keys, leaving stale entries in the session-lifetime `KbdActions` registry that later collided. The fix routes the swap through the existing (previously dead) `SwapItemGroups` method — which already unregisters then re-registers correctly — and guards the trailing unconditional `RegisterNavigation()` in `RemoveSpecificControlGroupAsync` with a method-local `bool` so the zero-item skip path does not double-register. Part B adds seven additive `logger.Debug(...)` calls across three folder-confidence scoring sites plus a new `logger` field in `QfcHighConfidencePreFilter.cs`, with no control-flow change. + +**Remediation cycle 1 changes verified in this review:** (1) the machine-readable Cobertura coverage artifact is now persisted at `artifacts/csharp/coverage.xml` and `.../evidence/coverage/2026-07-03T16-58/coverage.xml` (byte-identical, SHA-256 `a80f5ae3...`), resolving the prior Blocker; (2) the `QfcDatamodel` caller-context log string now correctly names `ScoreRemainingQueueMailItemAsync`, resolving the prior Minor. + +**What changed:** 4 C# production files (`QfcCollectionController.cs` +12 net; `QfcDatamodel.cs` +4; `QfcHighConfidencePreFilter.cs` +9; `QfcItemController.FolderHandling.cs` +20) and 1 test file (`QfcCollectionControllerTests.cs` +172, four new MSTest regression tests). The remaining diff is feature-folder docs, evidence artifacts (including the persisted coverage XML), and task-researcher memory markdown. The larger dequeue-time high-confidence rework is intentionally excluded and tracked as feature #233. + +**Top 3 risks:** +1. Repo-wide raw coverage (76.57%) remains below the generic 80% floor; this is the pre-existing, ratified COM/VSTO/WinForms exemption state, flat within variance and neither introduced nor worsened by this change (non-blocking). +2. The guard `swapAlreadyRegistered` correctly suppresses the trailing register only on the zero-item skip branch; an incorrect guard could silently leave the incoming page unregistered. The behavior is asserted by the new tests, mitigating this. +3. `QfcCollectionController.cs` is COM/WinForms coverage-exempt, so Part A behavior is verified through a `GetUninitializedObject` + reflection-injected seam rather than direct coverage; the seam is unusual but deterministic. + +**PR readiness recommendation:** **Go** — implementation quality supports merge; both prior blocking/minor findings are resolved and coverage is now artifact-verified.

This eliminates the divergence between the defective `ActivateQueuedItemGroups`-only path and the already-correct sibling method, aligning with the repository's simplicity-first and reusability principles. +- **Minimal, targeted guard.** The double-registration hazard is addressed with a single method-scoped `bool swapAlreadyRegistered`, set only on the zero-item skip branch and checked immediately before the trailing `RegisterNavigation()`. This is the smallest change that preserves the existing control flow while removing the reachable collision. +- **Rationale comments.** Both Part A edits carry `why`-focused comments citing Issue #232, explaining the stale-key mechanism and the double-registration guard — appropriate for a non-obvious bookkeeping fix. +- **Purely additive logging (Part B).** All seven log calls are appended after already-computed values; no return value, threshold, or branch is altered. The new `logger` field in `QfcHighConfidencePreFilter.cs` follows the established `log4net.LogManager.GetLogger(...DeclaringType)` pattern used elsewhere in the file family. The `QfcDatamodel` caller-context string is now accurate after the cycle-1 correction. + +#### Type safety and API notes + +- No public API surface changed: `LoadControlsAndHandlers_01`, `SwapItemGroups`, and `RemoveSpecificControlGroupAsync` signatures and callers are unchanged. +- Log interpolation uses null-conditional access (`ItemHelper?.Subject`, `_folderHandler?.Suggestions?.TopScore() ?? 0`, `mailItem.Subject`), consistent with the codebase and nullable-safe. The nullable forced-recompile shows zero new diagnostics. +- The `KbdActions.Add` throw-on-duplicate contract is preserved unchanged; the fix removes the reachable duplicate rather than masking it (the rejected Approach B). + +#### Error handling and logging + +- The fix does not introduce or catch new exception types; it removes the reachability of the reported `ArgumentException` for the documented scenario. +- Debug logging is gated by the existing log4net root level; no new configuration key. Log volume is one line per item per scoring site, bounded by page/batch size and consistent with pre-existing `logger.Debug` usage. +- The `removespecificcontrolgroupcounter` reentrancy-counter hygiene issue is intentionally left unchanged (documented follow-up); the guard uses a separate local and does not perturb the counter. + +--- + +## Test Quality Audit + +The four new Part A tests are deterministic and hermetic: they construct an uninitialized controller via `FormatterServices.GetUninitializedObject`, inject a real in-memory `KbdActions` behind a Loose `IQfcKeyboardHandler`, and force `IQfcFormViewer.L1v0L2L3v_TableLayout` to null to avoid WinForms-bound paths. `_digits = 1` is deliberately set to bypass the `SetVisualDigits` WinForms path — a documented, understood workaround for the seam. Part B is verified as behavior-preserving by running the 29 pre-existing tests over the three affected files with no assertion changes (AC7). + +### Reviewed test and QA artifacts + +- `QuickFiler.Test/Controllers/QfcCollectionControllerTests.cs` — 4 new tests covering register/unregister ordering, duplicate-key throw, and guarded-skip final state; mock-based, no I/O. +- `evidence/regression-testing/reported-repro.expect-fail.md` / `reported-repro.pass-after-fix.md` — the reported-repro boundary before/after the fix. +- `evidence/regression-testing/swap-register-unregister-order.pass.md` — AC1 ordering assertion. +- `evidence/regression-testing/double-registration-guard.pass.md` — AC3 guard behavior. +- `evidence/regression-testing/part-b-logging-no-regression.md` — 29/29 pre-existing tests pass over the Part B call sites. +- `evidence/qa-gates/vstest-final.2026-07-03T16-58.md` — 4641/4641 pass. +- `evidence/qa-gates/coverage-verification.2026-07-03T16-58.md` and `evidence/coverage/2026-07-03T16-58/coverage.xml` — coverage verified from the persisted Cobertura artifact (100% changed-line on the non-exempt file; repo-wide flat). + +### Quality assessment prompts + +- **Determinism:** No randomness, time, network, filesystem, or COM; Moq + in-memory registry. +- **Isolation:** Each test targets a single behavior with fresh instances. +- **Speed:** Full suite 52.88s; Part B subset ~1.3s. +- **Diagnostics:** FluentAssertions with message matchers (`*Key 2 SourceId Collection*`) and precise count assertions. + +--- + +## Security / Correctness Checks + +| Check | Status | Evidence | +|---|---|---| +| No secrets in code | PASS | Diff contains only control-flow fix and debug logging of Subject/EntryID/Score; no credentials. | +| No unsafe subprocess or command construction | PASS | No process/shell invocation in the change. | +| Input validation at boundaries | PASS | Registry-membership invariant enforced by the swap; null-conditional access in log calls. | +| Error handling remains explicit | PASS | Throw-on-duplicate contract preserved; reachable collision removed, not swallowed. | +| Configuration / path handling is safe | N/A | No config or path handling changed. | +| Diagnostic logging does not leak sensitive data beyond existing convention | PARTIAL | Debug logs include mail Subject/EntryID, consistent with existing `logger.Debug` usage in this file family; gated by log4net level. Acceptable per established convention, worth noting for privacy-sensitive deployments. Non-blocking. | + +--- + +## Research Log + +No external research was required. The review is grounded in the branch diff (`git diff 00507b59..b495fd34`), the feature-folder `spec.md`/`issue.md`, the `evidence/qa-gates/*` and `evidence/regression-testing/*` artifacts, direct inspection of the persisted Cobertura `coverage.xml` (SHA-256 and root/class line-rate confirmed), and direct file-line inspection of the four changed C# files and the test file. + +--- + +## Verdict + +The implementation is correct, minimally scoped, and well-evidenced. Part A removes the reachable `ArgumentException` by reusing the already-correct `SwapItemGroups` and guarding the trailing register; Part B is strictly additive logging with no behavioral impact, confirmed by 29 unchanged passing tests. Format, analyzer, and test gates are clean; the nullable gate's non-zero exit is a pre-existing legacy-project condition with a proven zero-delta error population. + +Both findings that made cycle 0 a Conditional Go are resolved: the machine-readable C# coverage artifact is persisted and independently verified, and the `QfcDatamodel` caller-context string is corrected. The change is **Go** with 0 blocking findings; the remaining items (test file at the 500-line cap, pre-existing controller size, repo-wide raw coverage under the generic floor covered by the ratified exemption) are non-blocking and documented as follow-ups. This conclusion is consistent with the Findings Table and the PR readiness recommendation above. diff --git a/docs/features/active/2026-07-03-quickfiler-navigation-key-collision-232/feature-audit.2026-07-03T17-25.md b/docs/features/active/2026-07-03-quickfiler-navigation-key-collision-232/feature-audit.2026-07-03T17-25.md new file mode 100644 index 000000000..91b62fdfa --- /dev/null +++ b/docs/features/active/2026-07-03-quickfiler-navigation-key-collision-232/feature-audit.2026-07-03T17-25.md @@ -0,0 +1,115 @@ +# Feature Audit: QuickFiler Navigation-Key Collision Fix (Issue #232) + +**Audit Date:** 2026-07-03 +**Feature Folder:** `docs/features/active/2026-07-03-quickfiler-navigation-key-collision-232` +**Base Branch:** `main` +**Head Branch:** `TaskMaster-wt-2026-07-03-10-11` +**Work Mode:** `full-bug` +**Audit Type:** Exit acceptance re-audit after remediation cycle 1 (full branch diff vs base) + +--- + +## Scope and Baseline + +- **Base branch:** `main` (commit `00507b595297c3e6970634a1855f1144c987dbdf`) +- **Head branch/commit:** `TaskMaster-wt-2026-07-03-10-11` (commit `b495fd34e341b4816be8676295c3f4a04613764b`) +- **Merge base:** `00507b595297c3e6970634a1855f1144c987dbdf` +- **Evidence sources:** + - Primary: `artifacts/pr_context.summary.txt` + - Secondary baseline diff: `artifacts/pr_context.appendix.txt` + - Feature evidence: `docs/features/active/2026-07-03-quickfiler-navigation-key-collision-232/evidence/**` + - Coverage artifact: `evidence/coverage/2026-07-03T16-58/coverage.xml` (byte-identical to `artifacts/csharp/coverage.xml`) + - Additional evidence: `git diff 00507b59..b495fd34` (authoritative scope) +- **Feature folder used:** `docs/features/active/2026-07-03-quickfiler-navigation-key-collision-232` +- **Requirements source:** `spec.md` (full-bug work mode → `spec.md` only) +- **Work mode resolution note:** `issue.md` line 12 declares `- Work Mode: full-bug`, which resolves the authoritative AC source to `spec.md` only (per acceptance-criteria-tracking). +- **Scope note:** Full-branch audit against base; scope was verified from `git diff` directly because the PR context summary overview under-reports the C# changes (`Core logic changes: 0 files`).

The branch delivers two bundled, non-overlapping C# changes: (Part A) a navigation-key duplicate-registration crash fix in `QfcCollectionController.cs` with four new MSTest regression tests, and (Part B) additive folder-confidence probability debug logging across three controller files. The excluded larger dequeue-time high-confidence rework (feature #233) is out of scope by design and confirmed untouched. + +Remediation cycle 1 addressed the sole prior blocking finding — the absent machine-readable C# coverage artifact — by regenerating and persisting the Cobertura `coverage.xml` at the canonical `artifacts/csharp/coverage.xml` and a committable copy under the feature evidence tree, then re-verifying coverage directly from that artifact. Cycle 1 also applied a one-line caller-context log-string correction in `QfcDatamodel.cs` (the string previously named a different method than the one it was emitted from; it now correctly names `ScoreRemainingQueueMailItemAsync`). + +All four toolchain gates are accounted for: csharpier (0 files changed), .NET analyzers (0 errors, no new diagnostics), and MSTest (4641/4641 pass) are clean; the nullable gate exits non-zero solely due to pre-existing legacy VSTO nullable debt, with a documented byte-identical before/after error population proving zero new nullable diagnostics from this change. The four regression tests are deterministic, isolated, and mock-based (no live-Outlook/COM dependency, no temp files). + +**Blocking findings: 0.** The prior blocking coverage-artifact finding is resolved and independently verified from the persisted XML. Coverage now verifies directly from a machine-readable artifact: the non-exempt `QfcHighConfidencePreFilter.cs` changed lines are 100% (>= 90%), and repo-wide coverage is flat at ~76.57% (exemption-governed testable denominator). Remaining items are non-blocking and pre-existing: repo-wide raw coverage below the generic 80% floor (ratified exemption), the 2308-line `QfcCollectionController.cs` (pre-existing overage), and the test file now at exactly the 500-line cap. + +**Policy documents evaluated:** +- `CLAUDE.md` (all sections; C# Code Change Policy, General/C# Unit Test Policy, COM/VSTO/WinForms coverage exemption) +- `.claude/rules/general-code-change.md` +- `.claude/rules/general-unit-test.md` +- `.claude/rules/csharp.md` (via CLAUDE.md embedded C# policy) + +**Language-specific policies evaluated:** +- N/A `python-*` (no Python files changed) +- N/A `powershell-*` (no PowerShell files changed) +- N/A Bash / JSON (no such files changed) +- C# Code Change Policy + C# Unit Test Policy (MSTest/Moq/FluentAssertions) + +**Temporary artifacts cleanup:** +- No temporary/one-time scripts were created by this review (review is check-only, no mutation of source or policy). +- N/A No ongoing tooling scripts were added by the change. + +--- + +## 1.

This audit verified directly from the XML: all six `` elements mapped to `QfcHighConfidencePreFilter.cs` report line-rate=1 (100% >= 90%); repo-wide root line-rate 0.76575 (40355/52700), flat versus baseline.

Verified in `git diff 00507b59..b495fd34 -- QuickFiler/Controllers/QfcDatamodel.cs`; provenance recorded in `evidence/other/qfcdatamodel-string-correction.2026-07-03T16-58.md`. +- **Repo-wide raw coverage below the 80% generic floor.** 76.5750% (40355/52700) across 7 first-party assemblies (UtilitiesCS 88.1%, QuickFiler 52.5%, TaskMaster 53.3%, Swordfish.NET.General 46.5%, TaskVisualization 18.3%, ToDoModel 2.3%, Tags 0%). This is a pre-existing repository state covered by the ratified COM/VSTO/WinForms testable-denominator exemption (CLAUDE.md; Issue #227). Not introduced or worsened by this change (flat within variance). Non-blocking. +- **`QfcCollectionController.cs` exceeds the 500-line limit (2308 lines).** Pre-existing; the change adds a net +12 lines to a legacy COM-bound controller.

That exclusion is a design decision recorded in `spec.md` Scope & Non-Goals and confirmed untouched by AC8 evidence; it is not a caller-imposed narrowing of the audit scope. No narrowing to a plan, task, phase, or file subset was attempted. + +## PR Context Summary Classification Note + +The regenerated PR context summary overview (`artifacts/pr_context.summary.txt`, "Changed files overview") reports `Core logic changes: 0 files` and buckets the changed C# files under docs/tooling. This is a known summary-generation misclassification. This audit derived scope from `git diff 00507b59..b495fd34` directly (authoritative), which surfaces all five C# files (4 production + 1 test). Any coverage hook that reads changed languages from the summary overview would under-enforce C# coverage; this audit verified C# coverage directly from the persisted Cobertura artifact. + +## Evidence Location Compliance + +Scanned the branch diff for files under `artifacts/baselines/`, `artifacts/qa/`, `artifacts/evidence/`, or `artifacts/coverage/`. **No violations found** — all evidence artifacts are written under the canonical `docs/features/active/2026-07-03-quickfiler-navigation-key-collision-232/evidence/{baseline,qa-gates,regression-testing,coverage,other}/` tree. The persisted coverage XML is at the canonical evidence path `evidence/coverage/2026-07-03T16-58/coverage.xml` with a byte-identical canonical machine copy at `artifacts/csharp/coverage.xml` (an approved machine-readable-artifact location, not one of the prohibited `artifacts/{baselines,qa,evidence,coverage}/` paths). Note: the repo does not currently ship `validate_evidence_locations.py`; the scan was performed via `git diff --name-only` path inspection. No `EVIDENCE_LOCATION_OVERRIDE_REJECTED` conditions were triggered. + +--- + +## 9. Summary of Changes + +### Commits in This PR/Branch + +1.
