### Task T018 - Run final validation and manual checks

**Started**: 2026-06-14 10:38 **Completed**: 2026-06-14 10:43 **Duration**: 5 minutes

**Validation Commands**:

* `bun test ./src/extensions/trend-finder/__tests__/view-model.test.ts` - passed.
* `bun run test -- src/extensions/trend-finder/views/__tests__/brief-view.test.tsx` - passed.
* `bun test ./scripts/extensions/trend-finder/__tests__/static-brief-export.test.ts` - passed.
* `bun test ./scripts/extensions/trend-finder/__tests__/static-brief-renderer.test.ts` - passed.
* `bun test ./src/extensions/trend-finder/__tests__/signal-workbench-model.test.ts` - passed.
* `bun run test -- src/extensions/trend-finder/components/__tests__/signal-workbench-view.test.tsx` - passed.
* `bun run typecheck` - passed.
* `bun run typecheck:scripts` - passed.
* `bun run test` - passed, 294 files and 3581 tests.
* `LC_ALL=C rg -nP '[^\x00-\x7F]' ...` over touched text files - no matches.

**Manual Browser Checks**:

* Desktop Brief route: `http://127.0.0.1:5189/extensions/trend-finder/brief`.
* Desktop screenshot: `.cache/extensions/trend-finder/session09-screenshots/brief-decisions-desktop.png`.
* Mobile screenshot: `.cache/extensions/trend-finder/session09-screenshots/brief-decisions-mobile.png`.
* Observed Decisions panel with explicit unavailable copy in the current local live payload.
* Desktop showed the Decisions header, unavailable callout, four verdict groups, and following Movement Groups without obvious overlap.
* Mobile showed the unavailable callout and stacked verdict groups with wrapping text and no obvious overlap.

**Residual Risks**:

* Local `src/data/live-data.json` currently exercises the unavailable Decisions state. Available-state UI is covered through view, model, static export, renderer, and Workbench tests using fixture data.
* Static export uses all generated topics for Decisions totals, while the live Brief view filters through visible ranked Brief topics. Tests lock both contexts.

**Files Changed**:

* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T018 and completion checklist complete.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - recorded final validation, screenshots, and residual risks.
* `.cache/extensions/trend-finder/session09-screenshots/brief-decisions-desktop.png` - refreshed desktop evidence.
* `.cache/extensions/trend-finder/session09-screenshots/brief-decisions-mobile.png` - refreshed mobile evidence.

**BQC Fixes**:

* Final typecheck caught a test-only action fixture missing required display fields; the fixture now preserves the full schema contract before overriding verdict-specific fields.
* Full Vitest suite confirmed no cross-view regression from the Brief and Workbench changes.

***

### Task T017 - Add static export, renderer, and Workbench preset tests

**Started**: 2026-06-14 10:34 **Completed**: 2026-06-14 10:38 **Duration**: 4 minutes

**Notes**:

* Added static export assertions for projected Decisions schema shape, verdict ordering, QA caution projection, privacy scanning, and legacy/default unavailable state.
* Added static renderer coverage proving Decisions HTML renders from `report.decisions` even when topic and evidence report rows are empty.
* Added Signal Workbench model coverage for usable action row projection, Decision queue filtering, verdict sort ordering, facets, summary counts, and stale filter revalidation.
* Added Signal Workbench view coverage for the Decision queue preset switching to flat mode, filtering default rows out, and resetting when re-entering with legacy/default action payloads.

**Validation**:

* `bun test ./scripts/extensions/trend-finder/__tests__/static-brief-export.test.ts` - passed.
* `bun test ./scripts/extensions/trend-finder/__tests__/static-brief-renderer.test.ts` - passed.
* `bun test ./src/extensions/trend-finder/__tests__/signal-workbench-model.test.ts` - passed.
* `bun run test -- src/extensions/trend-finder/components/__tests__/signal-workbench-view.test.tsx` - passed.

**Files Changed**:

* `scripts/extensions/trend-finder/__tests__/static-brief-export.test.ts` - added Decisions projection and unavailable-state coverage.
* `scripts/extensions/trend-finder/__tests__/static-brief-renderer.test.ts` - added projected-only Decisions renderer coverage.
* `src/extensions/trend-finder/__tests__/signal-workbench-model.test.ts` - added action verdict filter, sort, facet, and revalidation coverage.
* `src/extensions/trend-finder/components/__tests__/signal-workbench-view.test.tsx` - added Decision queue preset and reset coverage.
* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T017 complete and updated progress totals.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - recorded test coverage.

**BQC Fixes**:

* Projection boundary: renderer test keeps Decisions visible without relying on raw topic rows.
* Reset behavior: model and view tests lock action filters back to all rows when usable action verdicts disappear.

***

### Task T016 - Add Brief Decisions view tests

**Started**: 2026-06-14 09:23 **Completed**: 2026-06-14 10:34 **Duration**: 71 minutes

**Notes**:

* Added happy-dom Brief view coverage for Decisions rendering, grouped verdict counts, reason chips, QA caution summaries, explicit legacy/unavailable copy, panel accessibility, visibility hide/restore behavior, and long topic text rendering.
* Validation: `bun run test -- src/extensions/trend-finder/views/__tests__/brief-view.test.tsx` passed.

**Files Changed**:

* `src/extensions/trend-finder/views/__tests__/brief-view.test.tsx` - added Decisions section rendering and interaction coverage.
* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T016 complete and updated progress totals.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - recorded Brief view test coverage.

**BQC Fixes**:

* Accessibility alignment: tests query the Decisions section by region/heading and restore hidden panels through the existing Visibility menu contract.
* Responsive safety: long topic names remain rendered in the decision row instead of disappearing from the Brief surface.

## Task Log

### 2026-06-14 - Session Start

**Environment verified**:

* [x] Prerequisites confirmed
* [x] Tools available
* [x] Directory structure ready

**Notes**:

* Active session resolved from `.spec_system/state.json` via analyze script.
* Environment prerequisite check passed with Bun 1.3.14, jq 1.7, and git.
* Behavioral Quality Checklist is active because this session changes application code.

***

### Task T001 - Verify prerequisite sessions, source mapping, and target paths

**Started**: 2026-06-14 08:08 **Completed**: 2026-06-14 08:09 **Duration**: 1 minute

**Notes**:

* Confirmed `phase28-session09-action-queue-surface` is the current session from the analysis script.
* Confirmed Session 08 and earlier dependency sessions are completed in `.spec_system/state.json`.
* Verified the PRD source mapping references the Trends-Finderz action queue files and keeps the standalone route out of scope.
* Verified existing target implementation and test files. `src/extensions/trend-finder/views/__tests__/brief-view.test.tsx` and this notes file are expected new files.

**Files Changed**:

* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T001 complete and updated progress totals.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - recorded setup verification.

**BQC Fixes**:

* N/A - setup verification only.

***

### Task T002 - Compare Trends-Finderz action queue references

**Started**: 2026-06-14 08:09 **Completed**: 2026-06-14 08:11 **Duration**: 2 minutes

**Notes**:

* Compared `buildActionQueueFromData` and the reference `ActionQueueView` against the shipped Trend Finder action fields.
* Reused the reference ordering pattern: `act_now`, `monitor`, `review`, `ignore`.
* Kept the dedicated `/action-queue` route, API load flow, watchlist writes, and standalone page chrome out of scope.
* Confirmed shipped fields are `actionRecommendation` and `actionConsistency` on `TopicCardViewModel`, backed by the Session 08 enum values and label helpers.

**Files Changed**:

* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T002 complete and updated progress totals.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - recorded reference comparison.

**BQC Fixes**:

* Trust boundary enforcement: confirmed static/export work must consume projected view-model fields, not raw payload reads.

***

### Task T003 - Create implementation-notes shell

**Started**: 2026-06-14 08:08 **Completed**: 2026-06-14 08:12 **Duration**: 4 minutes

**Notes**:

* Created the live implementation notes before source edits as required by the implement workflow.
* Added progress, setup verification, task log, BQC, and validation placeholders through the initial task entries.

**Files Changed**:

* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T003 complete and updated setup progress.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - created and populated implementation log.

**BQC Fixes**:

* N/A - notes-only task.

***

### Task T004 - Add Decisions Brief grouping view model

**Started**: 2026-06-14 08:12 **Completed**: 2026-06-14 08:23 **Duration**: 11 minutes

**Notes**:

* Added a bounded `BriefDecisionsViewModel` with stable verdict order: Act now, Monitor, Review, Ignore.
* Sorted topics within each verdict by action score, urgency, rank, and topic ID.
* Aggregated top action reasons and QA caution summaries per group.
* Added explicit empty and legacy-unavailable states. All-default Session 08 action fields are treated as unavailable rather than real Review decisions.
* Validation: `bun test ./src/extensions/trend-finder/__tests__/view-model.test.ts` passed. An initial pathless Bun filter invocation did not match test files; reran with `./`.

**Files Changed**:

* `src/extensions/trend-finder/view-model.ts` - added Decisions grouping types and helper.
* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T004 complete and updated progress totals.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - recorded model implementation.

**BQC Fixes**:

* State freshness on re-entry: legacy/default action payloads now produce an explicit unavailable model instead of stale-looking Review groups.
* Contract alignment: view-model groups are typed by the shipped `TrendActionVerdict` enum and sorted exhaustively.

***

### Task T005 - Add static Brief Decisions projection contract

**Started**: 2026-06-14 08:23 **Completed**: 2026-06-14 08:29 **Duration**: 6 minutes

**Notes**:

* Added a `decisions` field to `StaticBriefReportSchema` with bounded groups, topic rows, reason summaries, and QA caution summaries.
* Projected Decisions from `getBriefDecisionsViewModel` and sanitized all browser-visible strings through the existing static export helpers.
* Kept the renderer contract narrowed to `report.decisions`; renderer implementation is a later task.
* Validation: `bun test ./scripts/extensions/trend-finder/__tests__/static-brief-export.test.ts` passed.

**Files Changed**:

* `scripts/extensions/trend-finder/static-brief-export.ts` - added Decisions schema defaults and projection.
* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T005 complete and updated progress totals.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - recorded static projection work.

**BQC Fixes**:

* Trust boundary enforcement: static export now projects Decisions before HTML rendering.
* Error information boundaries: projected strings continue through the existing sanitization and privacy scan path.

***

### Task T006 - Add Signal Workbench verdict preset contracts

**Started**: 2026-06-14 08:29 **Completed**: 2026-06-14 08:39 **Duration**: 10 minutes

**Notes**:

* Added Workbench row action verdict fields, labels, tones, score, urgency, QA state, and explicit `hasActionVerdict` detection.
* Added action verdict facets, filter state, decision preset state, deterministic action-verdict sort, and row-change filter revalidation helper.
* Kept legacy/default action rows out of explicit verdict filters and the decision preset.
* Validation: `bun test ./src/extensions/trend-finder/__tests__/signal-workbench-model.test.ts` passed.

**Files Changed**:

* `src/extensions/trend-finder/signal-workbench-model.ts` - added verdict contracts, filtering, sorting, facets, and revalidation.
* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T006 complete and updated progress totals.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - recorded Workbench model implementation.

**BQC Fixes**:

* State freshness on re-entry: added model revalidation for verdict filters when row data changes.
* Contract alignment: Workbench sort/filter contracts use shipped `TrendActionVerdict` values and preserve deterministic tie breakers.

***

### Task T007 - Add representative Decisions fixtures

**Started**: 2026-06-14 08:39 **Completed**: 2026-06-14 08:44 **Duration**: 5 minutes

**Notes**:

* Added stable fixture topic ID aliases for Act now, Monitor, Review, Ignore, QA review, and QA blocked cases.
* Added `LEGACY_ACTION_UNAVAILABLE_TREND_FINDER_DATA` with all topics reset to default action fields for unavailable-state coverage.
* Validation: `bun test ./src/extensions/trend-finder/__tests__/view-model.test.ts` passed.

**Files Changed**:

* `src/extensions/trend-finder/fixtures.ts` - added Decisions fixture aliases and legacy unavailable fixture.
* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T007 complete and updated progress totals.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - recorded fixture update.

**BQC Fixes**:

* State freshness on re-entry: legacy fixture now exercises default action payloads explicitly.

***

### Task T008 - Add Brief visibility metadata

**Started**: 2026-06-14 08:44 **Completed**: 2026-06-14 08:46 **Duration**: 2 minutes

**Notes**:

* Added `panel:decisions` to the Brief visibility menu between Today's pick and Movement groups.
* Existing panel IDs and item hidden-state keys were left unchanged.

**Files Changed**:

* `src/extensions/trend-finder/views/brief-view.tsx` - added Decisions visibility menu metadata.
* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T008 complete and updated progress totals.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - recorded visibility metadata update.

**BQC Fixes**:

* State freshness on re-entry: preserved existing visibility keys so stored hidden state remains valid.

***

### Task T009 - Render Decisions Brief section

**Started**: 2026-06-14 08:46 **Completed**: 2026-06-14 08:55 **Duration**: 9 minutes

**Notes**:

* Rendered a dense Decisions panel grouped by Act now, Monitor, Review, and Ignore.
* Included per-group counts, top reason chips, QA caution summaries, top topic rows, next-step copy, action score, urgency, score band, and warning summaries.
* Added explicit Decisions empty and legacy-unavailable states. Existing Brief loading, disabled, and error states continue to cover page-level lifecycle states.
* Validation: `bun run typecheck` passed.

**Files Changed**:

* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T009 complete and updated progress totals.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - recorded Brief rendering work.

**BQC Fixes**:

* Failure path completeness: Decisions now has explicit empty and unavailable copy.
* Accessibility and platform compliance: section, groups, counts, and topic rows expose stable labels and use native buttons only where existing controls already do.

***

### Task T010 - Integrate Decisions visibility and responsive layout

**Started**: 2026-06-14 08:55 **Completed**: 2026-06-14 08:56 **Duration**: 1 minute

**Notes**:

* Added the `panel:decisions` visibility panel to the Brief render path.
* Fed Decisions from visible ranked topics so existing topic hide/show state affects the panel without new hidden-state contracts.
* Used wrapping text, bounded rows, and responsive grid tracks from one to four columns.
* Validation: `bun run typecheck` passed after the Brief view changes.

**Files Changed**:

* `src/extensions/trend-finder/views/brief-view.tsx` - wired Decisions panel into visibility controls and responsive layout.
* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T010 complete and updated progress totals.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - recorded visibility integration.

**BQC Fixes**:

* State freshness on re-entry: Decisions recomputes from currently visible topic rows.
* Accessibility and platform compliance: visibility menu and panel use the existing keyboard-accessible visibility components.

***

### Task T011 - Project Decisions into static Brief report

**Started**: 2026-06-14 08:23 **Completed**: 2026-06-14 08:58 **Duration**: 35 minutes elapsed with T005 projection work

**Notes**:

* `projectStaticBriefReport` now includes `decisions` from `getBriefDecisionsViewModel`.
* Projected rows include bounded topic rows, top reasons, QA cautions, unavailable state copy, and sanitized labels only.
* Validation: `bun test ./scripts/extensions/trend-finder/__tests__/static-brief-export.test.ts` passed after the projection change.

**Files Changed**:

* `scripts/extensions/trend-finder/static-brief-export.ts` - emitted projected Decisions in the static report.
* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T011 complete and updated progress totals.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - recorded projection integration.

**BQC Fixes**:

* Trust boundary enforcement: static HTML receives projected `report.decisions` only.

***

### Task T012 - Render static Brief Decisions HTML

**Started**: 2026-06-14 08:58 **Completed**: 2026-06-14 09:03 **Duration**: 5 minutes

**Notes**:

* Rendered a static Decisions panel from `report.decisions` only.
* Included unavailable copy, group counts, top reasons, QA caution rows, and projected topic rows.
* Validation: `bun test ./scripts/extensions/trend-finder/__tests__/static-brief-renderer.test.ts` passed.

**Files Changed**:

* `scripts/extensions/trend-finder/static-brief-renderer.ts` - rendered projected Decisions HTML.
* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T012 complete and updated progress totals.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - recorded static renderer work.

**BQC Fixes**:

* Trust boundary enforcement: renderer reads only projected `StaticBriefReport` fields.
* Error information boundaries: renderer continues escaping text, attributes, and inline JSON through existing helpers.

***

### Task T013 - Wire Signal Workbench verdict preset UI

**Started**: 2026-06-14 09:03 **Completed**: 2026-06-14 09:08 **Duration**: 5 minutes

**Notes**:

* Added a Decision preset segmented control and explicit verdict filter to Signal Workbench controls.
* Selecting the Decision queue preset switches sorting to action verdict priority and flat view for deterministic scanning.
* Added row-change filter revalidation and a Decisions status chip.
* Validation: `bun run typecheck` passed.
* Validation: `bun run test -- src/extensions/trend-finder/components/__tests__/signal-workbench-view.test.tsx` passed.
* Note: direct `bun test ./src/extensions/trend-finder/components/__tests__/signal-workbench-view.test.tsx` failed because it does not load the repo's DOM test environment.

**Files Changed**:

* `src/extensions/trend-finder/components/signal-workbench-controls.tsx` - added Decision preset and verdict filter controls.
* `src/extensions/trend-finder/views/signal-workbench-view.tsx` - wired preset sort behavior, filter revalidation, and status count.
* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T013 complete and updated progress totals.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - recorded Workbench UI wiring.

**BQC Fixes**:

* State freshness on re-entry: stale action verdict filters are reset when rows no longer support them.
* Accessibility and platform compliance: preset controls use native buttons with `aria-pressed`, labels, and focus rings.

***

## Design Decisions

### Decision 1: Brief-first Decisions surface

**Context**: The PRD asked for a compact answer to "what should I do next?" without adding a standalone route unless the Brief became cramped. **Options Considered**:

1. Add a standalone Action Queue route - more space, but out of scope and duplicates routing/navigation.
2. Add a Decisions section to Brief - smaller surface, keeps static export aligned, and follows the PRD preference.

**Chosen**: Add the Decisions section to Brief. **Rationale**: The current layout can support a bounded four-group section. Standalone route remains a follow-up only if real operator usage proves the Brief is too cramped.

### Decision 2: Legacy action defaults are unavailable

**Context**: Parsed legacy payloads can receive default Session 08 action fields that look like real Review verdicts. **Options Considered**:

1. Group default Review rows as Review - simple, but misleading.
2. Detect all-default action recommendation and consistency fields - safer and explicit.

**Chosen**: Treat all-default action fields as unavailable. **Rationale**: This prevents legacy payloads from appearing to recommend Review when no usable action verdict exists.

### Decision 3: Static renderer consumes projected Decisions only

**Context**: Static export privacy depends on project-before-render boundaries. **Options Considered**:

1. Let renderer compute Decisions from topic payloads - duplicates logic and risks raw payload reads.
2. Project `report.decisions` in `projectStaticBriefReport` - one narrowed contract for HTML.

**Chosen**: Project Decisions before rendering. **Rationale**: The renderer now reads only `StaticBriefReport` fields and preserves the existing privacy scan path.

***

## Projection Privacy Notes

* Static Decisions projection uses `getBriefDecisionsViewModel` and emits only bounded labels, counts, reason summaries, QA summaries, and topic display rows.
* Renderer reads only `report.decisions`; it does not access raw Trend Finder topic payloads, prompts, provider responses, local paths, source dumps, or local triage notes.
* Existing `assertStaticBriefPrivacy` remains on the final report object.

***

## UI Checks And Screenshots

* Desktop Decisions check: `.cache/extensions/trend-finder/session09-screenshots/brief-decisions-desktop.png`
* Mobile Decisions check: `.cache/extensions/trend-finder/session09-screenshots/brief-decisions-mobile.png`
* Observed local live payload state: explicit Decisions-unavailable copy rendered because `src/data/live-data.json` does not contain usable Session 08 action verdicts.
* No blank panel, no obvious text overlap, and the Decisions visibility control appeared in the accessibility snapshot.

***

## Validation Commands

* `bun test ./src/extensions/trend-finder/__tests__/view-model.test.ts` - passed.
* `bun test ./scripts/extensions/trend-finder/__tests__/static-brief-export.test.ts` - passed.
* `bun test ./src/extensions/trend-finder/__tests__/signal-workbench-model.test.ts` - passed.
* `bun run typecheck` - passed.
* `bun run test -- src/extensions/trend-finder/components/__tests__/signal-workbench-view.test.tsx` - passed.
* `bun test ./scripts/extensions/trend-finder/__tests__/static-brief-renderer.test.ts` - passed.

***

## Follow-up Route Decision

* Standalone `/action-queue` route remains deferred.
* Follow-up trigger: add a route only if the bounded Brief Decisions section proves cramped during operator use or needs write-capable actions after Session 10 pin/notes work.

***

### Task T014 - Record implementation decisions and visual evidence

**Started**: 2026-06-14 09:08 **Completed**: 2026-06-14 09:17 **Duration**: 9 minutes

**Notes**:

* Recorded grouping choices, projection privacy notes, validation commands, screenshot paths, and the follow-up route decision.
* Captured desktop and mobile screenshots through the local Vite route.
* Live local data showed the unavailable Decisions state, which verifies the legacy/default action copy path.

**Files Changed**:

* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T014 complete and updated implementation progress.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - added decision, privacy, screenshot, validation, and route-decision sections.

**BQC Fixes**:

* Failure path completeness: verified browser-visible unavailable copy with the current local payload.

***

### Task T015 - Add Decisions view-model tests

**Started**: 2026-06-14 09:17 **Completed**: 2026-06-14 09:23 **Duration**: 6 minutes

**Notes**:

* Added tests for verdict order, counts, reason ordering, QA caution summaries, all-one-group ordering and bounds, and legacy unavailable state.
* Validation: `bun test ./src/extensions/trend-finder/__tests__/view-model.test.ts` passed.

**Files Changed**:

* `src/extensions/trend-finder/__tests__/view-model.test.ts` - added Decisions helper coverage.
* `.spec_system/specs/phase28-session09-action-queue-surface/tasks.md` - marked T015 complete and updated progress totals.
* `.spec_system/specs/phase28-session09-action-queue-surface/implementation-notes.md` - recorded test work.

**BQC Fixes**:

* Contract alignment: tests lock shipped verdict ordering and default legacy unavailable behavior.
