Deliverables Verification ### Status: PASS #### Files Created | File | Found | Status | | ----------------------------------------------------------------------------------- | ----- | ------ | | `src/extensions/trend-finder/components/polarity-attention-grid.tsx` | Yes | PASS | | `src/extensions/trend-finder/components/__tests__/polarity-attention-grid.test.tsx` | Yes | PASS | #### Files Modified | File | Found | Status | | ------------------------------------------------------------------------- | ----- | ------ | | `scripts/lib/ai-runtime/source-breakdown.ts` | Yes | PASS | | `scripts/lib/ai-runtime/__tests__/source-breakdown.test.ts` | Yes | PASS | | `src/extensions/trend-finder/schema.ts` | Yes | PASS | | `src/extensions/trend-finder/fixtures.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/views/trends-view.tsx` | Yes | PASS | | `scripts/extensions/trend-finder/static-brief-export.ts` | Yes | PASS | | `scripts/extensions/trend-finder/static-brief-renderer.ts` | Yes | PASS | | `scripts/extensions/trend-finder/__tests__/static-brief-export.test.ts` | Yes | PASS | | `scripts/extensions/trend-finder/__tests__/static-brief-renderer.test.ts` | Yes | PASS | | `scripts/extensions/trend-finder/measure-payload-size.ts` | Yes | PASS | | `docs/extensions/trend-finder-scoring.md` | Yes | PASS | | `docs/extensions/trend-finder-ui-surfaces.md` | Yes | PASS | | `tests/e2e/trend-finder.spec.ts` | Yes | PASS | | `tests/e2e/trend-finder-static-brief.spec.ts` | Yes | PASS | ### Missing Deliverables None. *** ## 3. ASCII Encoding Check ### Status: PASS Changed and untracked files were scanned for non-ASCII characters and CRLF line endings. | Scope | Encoding | Line Endings | Status | | -------------------------------- | -------- | ------------ | ------ | | Session deliverables | ASCII | LF | PASS | | Session docs and reports | ASCII | LF | PASS | | Validation-touched support files | ASCII | LF | PASS | ### Encoding Issues None. *** ## 4. Test Results ### Status: PASS | Metric | Value | | ----------- | ------------- | | Total Tests | 3811 | | Passed | 3811 | | Failed | 0 | | Coverage | Not collected | ### Commands * `bun run test` - 314 test files passed, 3717 tests passed. * `bun run test:e2e` - 94 Playwright tests passed. * `bun run typecheck` - passed. * `bun run typecheck:scripts` - passed. * `bun run lint` - passed. * `bunx prettier --check ...` over current-session formatted files - passed. * `bun run scripts/extensions/trend-finder/measure-payload-size.ts src/data/live-data.example.json --threshold-kb=1024` - Trend Finder browser data payload 14,077 bytes; extension payload boundary 1,048,576 bytes. ### Failed Tests None after validation fixes. *** ## 5. Database/Schema Alignment ### Status: N/A N/A - this session introduced no database, migration, hosted storage, persisted schema, seed, or ORM changes. The changed schema is the browser/static JSON contract in `src/extensions/trend-finder/schema.ts`; it is additive and verified by unit tests, type checks, static export tests, and e2e guards. ### Issues Found N/A - no DB-layer changes. *** ## 6. Success Criteria From `spec.md`: ### Functional Requirements * [x] `attentionPattern` publishes on ranked topics with an explicit `unavailable` default for legacy data. * [x] Derivation produces `adoption`, `creator-hype`, `announcement`, `discourse`, and `unavailable` from deterministic role-share and title inputs. * [x] The field remains distinct from `actionRecommendation`; it labels observed attention shape and does not decide priority. * [x] Trends header renders a compact grid for movement, action verdict, attention pattern, and reserved reception. * [x] Static Brief exports and renders the same grid without raw source rows, prompts, private paths, tokens, or comment bodies. * [x] Payload size measurement remains under the shared 1 MB boundary. ### Testing Requirements * [x] Unit tests written and passing for source derivation and legacy schema parsing. * [x] View-model and component tests cover label/tone projection, empty states, ordering, and accessibility labels. * [x] Static Brief export and renderer tests cover report schema, escaped rendering, and privacy scan behavior. * [x] Playwright e2e guards cover the live Trends grid and exported static Brief grid on desktop/mobile. ### Quality Gates * [x] All files ASCII-encoded. * [x] Unix LF line endings. * [x] Code follows project conventions. *** ## 7. Conventions Compliance ### Status: PASS | Category | Status | Notes | | -------------- | ------ | -------------------------------------------------------------------------------------------------- | | Naming | PASS | `attentionPattern`, grid types, and helper names match existing Trend Finder language. | | File Structure | PASS | Component, tests, scripts, docs, and e2e files follow local placement conventions. | | Error Handling | PASS | Static export validation remains schema-backed; renderer escapes projected labels and attributes. | | Comments | PASS | No unnecessary commented-out code found. | | Testing | PASS | Focused unit, component, static export/rendering, QA, payload, and e2e coverage added or repaired. | ### 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/source-breakdown.ts` * `src/extensions/trend-finder/view-model.ts` * `src/extensions/trend-finder/components/polarity-attention-grid.tsx` * `scripts/extensions/trend-finder/static-brief-export.ts` * `scripts/extensions/trend-finder/static-brief-renderer.ts` | Category | Status | File | Details | | ------------------ | ------ | ------------------------------------------------------- | ------------------------------------------------------------------------------------ | | Trust boundaries | PASS | `static-brief-export.ts`, `static-brief-renderer.ts` | Static Brief consumes projected bounded rows and escapes rendered labels/attributes. | | Resource cleanup | PASS | `polarity-attention-grid.tsx` | No timers, subscriptions, sockets, or external resources introduced. | | Mutation safety | PASS | `trends-view.tsx`, `view-model.ts` | Grid projection is read-only and deterministic. | | Failure paths | PASS | `polarity-attention-grid.tsx`, `static-brief-export.ts` | Empty states and default `unavailable` paths are explicit. | | Contract alignment | PASS | `schema.ts`, `source-breakdown.ts`, `view-model.ts` | Enum/default/schema/projection contracts are tested and typechecked. | ### Violations Found None. ### Fixes Applied During Validation * Updated `scripts/extensions/trend-finder/__tests__/static-brief-qa.test.ts` for the new required static Brief section count. * Updated `tests/e2e/trend-finder-release-hardening.spec.ts` to assert the current scheduler warning summary text. * Removed unused type aliases from `scripts/extensions/trend-finder/mcp/server.ts` so repo-wide lint passes. * Formatted current-session code and docs with Prettier. ## Validation Result ### PASS All required session tasks are complete, deliverables exist, encoding is clean, tests and quality checks pass, no DB-layer alignment work is required, and the security/GDPR spot-check found no blockers. ### Required Actions None. ## Next Steps Run `updateprd` to mark session complete. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase29-session02-attention-pattern-and-polarity-grid/validation.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
