Deliverables Verification ### Status: PASS #### Files Created Or Modified | File | Found | Status | | ------------------------------------------------------------------------------------ | ----- | ------ | | `scripts/lib/ai-runtime/topic-quality.ts` | Yes | PASS | | `scripts/lib/ai-runtime/__tests__/topic-quality.test.ts` | Yes | PASS | | `src/extensions/trend-finder/components/suppressed-noise-summary.tsx` | Yes | PASS | | `src/extensions/trend-finder/components/__tests__/suppressed-noise-summary.test.tsx` | Yes | PASS | | `scripts/lib/ai-runtime/scoring.ts` | Yes | PASS | | `scripts/lib/ai-runtime/risk-flags.ts` | Yes | PASS | | `scripts/lib/ai-runtime/__tests__/scoring.test.ts` | Yes | PASS | | `scripts/lib/ai-runtime/__tests__/scoring-calibration.test.ts` | Yes | PASS | | `src/extensions/trend-finder/schema.ts` | Yes | PASS | | `src/extensions/trend-finder/view-model.ts` | Yes | PASS | | `src/extensions/trend-finder/__tests__/view-model.test.ts` | Yes | PASS | | `src/extensions/trend-finder/components/trend-card.tsx` | Yes | PASS | | `src/extensions/trend-finder/views/trends-view.tsx` | Yes | PASS | | `src/extensions/trend-finder/signal-workbench-model.ts` | Yes | PASS | | `src/extensions/trend-finder/__tests__/signal-workbench-model.test.ts` | Yes | PASS | | `src/extensions/trend-finder/components/signal-workbench-controls.tsx` | Yes | PASS | | `src/extensions/trend-finder/fixtures.ts` | Yes | PASS | | `docs/extensions/trend-finder-scoring.md` | Yes | PASS | ### Missing Deliverables None. *** ## 3. ASCII Encoding Check ### Status: PASS | File Set | Encoding | Line Endings | Status | | --------------------------------------------------------------- | -------- | ------------ | ------ | | Session deliverables, supporting tests, docs, and session files | ASCII | LF | PASS | ### Encoding Issues None. Commands: * `rg --pcre2 -n "[^\\x00-\\x7F]" ...` - no matches. * `grep -Il $'\\r' ...` - no matches. * `file ...` - deliverables reported ASCII text. *** ## 4. Test Results ### Status: PASS | Metric | Value | | ----------- | ------------- | | Total Tests | 3516 | | Passed | 3516 | | Failed | 0 | | Coverage | Not collected | ### Commands | Command | Result | | -------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------- | | `bun run test` | PASS - 288 test files, 3516 tests | | `bun run typecheck` | PASS | | `bun run typecheck:scripts` | PASS | | `bun run lint` | PASS | | `bunx vitest run src/lib/__tests__/trend-finder-dashboard.test.tsx scripts/lib/ai-runtime/__tests__/scoring-calibration.test.ts` | PASS - targeted rerun after validation fixes | ### Failed Tests None in the final run. ### Fixes Applied During Validation * Fixed `TrendsView` so a valid deep link to a suppressed topic reveals suppressed rows for that report and selects the requested topic instead of silently falling back. * Updated scoring calibration tests for `trend-finder-scoring-v28.4` and the new post-confidence topic-noise downrank metadata. * Removed unused imports from `scripts/lib/ai-runtime/topic-quality.ts`. * Tightened optional scoring metadata handling in `scripts/lib/ai-runtime/__tests__/scoring-calibration.test.ts`. *** ## 5. Database/Schema Alignment ### Status: N/A *N/A because the session introduced no DB-layer changes.* * [x] No migrations, database models, SQL, seeds, persisted data shape, or generated database types were changed. * [x] No local migration/status/diff command is applicable. ### Issues Found N/A - no DB-layer changes. *** ## 6. Success Criteria From spec.md: ### Functional Requirements * [x] Generic or listicle-shaped topics get deterministic medium/high noise risk and are downranked without being removed from the payload. * [x] Visibility bands carry machine-readable reason codes and bounded display labels. * [x] Early hidden gems stay visible when they meet the rescue rule and are not high-noise, stale, or unsupported. * [x] The Trends view default-hides `suppressed` topics behind an explicit control that lists how many low-signal topics were hidden and why. * [x] Manual per-view visibility controls continue to work as the operator override layer. * [x] Signal Workbench can filter by visibility band or noise risk. * [x] Legacy payloads parse with neutral defaults and existing fixtures remain usable. ### Testing Requirements * [x] Unit tests written and passing for topic-quality scoring, gate status, reason codes, and hidden-gem rescue. * [x] Scoring integration tests cover downrank behavior, fallback-mode quality bounds, and risk-flag integration. * [x] Schema/view-model tests cover legacy parsing and suppressed summary projection. * [x] Component or route tests cover default-hidden suppressed rows and the show affordance. * [x] Manual browser testing completed for Trends and Signal Workbench surfaces. ### Quality Gates * [x] All files ASCII-encoded. * [x] Unix LF line endings. * [x] Code follows project conventions. * [x] Focused and full tests pass. * [x] Type checking remains clean for changed files. Manual browser notes: * Opened `http://127.0.0.1:5189/extensions/trend-finder/trends#topic:topic-003` with `agent-browser`; current live data had no suppressed rows, and the suppressed summary rendered with a disabled zero-count control. * Opened Workbench, selected `NOISE = Low noise` and `VISIBILITY = Watch`; the table remained populated with 7 matching rows and controls remained accessible. * The suppressed-row fixture path is covered by component and dashboard tests, including the validation fix for suppressed topic deep links. *** ## 7. Conventions Compliance ### Status: PASS | Category | Status | Notes | | -------------- | ------ | ---------------------------------------------------------------------------------------------- | | Naming | PASS | New names use Trend Finder language and avoid new legacy `findtrend` or host-identity names. | | File Structure | PASS | Helpers, tests, components, view models, fixtures, and docs follow existing locations. | | Error Handling | PASS | Helper inputs use Zod validation and issue mapping; schema defaults keep legacy payloads safe. | | Comments | PASS | No commented-out code or unnecessary explanatory comments found. | | Testing | PASS | Focused tests stay near the behavior they cover and full suite passes. | ### Convention Violations None. *** ## 8. Security & GDPR Compliance ### Status: PASS **Full report**: See `security-compliance.md` in this session directory. #### Summary | Area | Status | Findings | | -------- | ------ | -------- | | Security | PASS | 0 issues | | GDPR | N/A | 0 issues | ### Critical Violations None. *** ## 9. Behavioral Quality Spot-Check ### Status: PASS **Checklist applied**: Yes **Files spot-checked**: * `scripts/lib/ai-runtime/topic-quality.ts` * `scripts/lib/ai-runtime/scoring.ts` * `src/extensions/trend-finder/schema.ts` * `src/extensions/trend-finder/views/trends-view.tsx` * `src/extensions/trend-finder/signal-workbench-model.ts` | Category | Status | File | Details | | ------------------ | ------ | ------------------------------------------------------ | ---------------------------------------------------------------------------------------- | | Trust boundaries | PASS | `topic-quality.ts`, `schema.ts` | Inputs and browser payload additions are validated and bounded. | | Resource cleanup | PASS | `trends-view.tsx` | Hash listener cleanup is preserved; no timers or subscriptions added. | | Mutation safety | PASS | `trends-view.tsx`, `signal-workbench-model.ts` | New controls are local deterministic filters; no new persisted mutation path. | | Failure paths | PASS | `topic-quality.ts`, `schema.ts` | Invalid helper inputs return issues and malformed/missing payload fields default safely. | | Contract alignment | PASS | `scoring.ts`, `schema.ts`, `signal-workbench-model.ts` | Shared enums and type checks align scoring, parser, UI, and tests. | ### Violations Found None. ### Fixes Applied During Validation * Revealed suppressed rows when a valid suppressed topic is requested by hash target. * Updated stale calibration assertions for scoring version and noise-downrank metadata. * Removed lint/typecheck violations introduced by validation test updates. *** ## Validation Result ### PASS All required tasks are complete, deliverables exist, file hygiene is clean, final tests and quality gates pass, DB/schema alignment is not applicable, and targeted security/GDPR review found no blocking issues. ### Required Actions None. ## Next Steps Run updateprd to mark session complete. --- # Agent Instructions This documentation is published with GitBook.
