Database/Schema Alignment ### Status: N/A *N/A because this session introduced no persisted database, migration, ORM, SQL, seed, or generated-type changes. `src/extensions/trend-finder/schema.ts` is the browser-safe Trend Finder payload schema, not a database schema.* * [x] Matching schema artifact exists for each relevant DB-layer change - N/A * [x] Code and schema artifacts are aligned - N/A * [x] Migration/status/diff check passed locally - N/A * [x] Seed or rollback updates included when conventions require them - N/A ### Issues Found N/A - no DB-layer changes. *** ## 6. Success Criteria From `spec.md`: ### Functional Requirements * [x] A five-day-old research signal and a five-day-old discussion signal decay differently according to role half-life configuration. * [x] Momentum recency uses half-life weighted freshness while the six-factor weight table remains unchanged. * [x] Each topic carries `signalAging` with status, score, age summary, stale counts, recent confirmation, old-source pressure, and bounded role contributions. * [x] Topics with missing or insufficient evidence show explicit unavailable aging state rather than guessed freshness. * [x] Saturation keeps the existing field and adds diffusion, density, mainstream pressure, and dominance handling without becoming a hidden score multiplier. * [x] Trend cards and Workbench rows expose aging and refined saturation through bounded labels, filters, and deterministic ordering. * [x] Trends-Finderz lifecycle labels are not introduced into Trend Finder payloads or UI. * [x] Legacy payloads parse with neutral defaults and existing fixtures remain usable. ### Testing Requirements * [x] Unit tests written and passing for half-life decay, status transitions, unavailable states, source-role contributions, and Trends-Finderz lifecycle threshold fixtures. * [x] Scoring integration tests cover role-specific recency differences, refined saturation behavior, legacy raw opportunity score behavior, and no score multiplier introduction. * [x] Source-config tests cover half-life defaulting, bounds, and invalid metadata warnings. * [x] Schema/view-model tests cover legacy defaults, labels, and bounded contribution projection. * [x] Workbench and Trend card tests cover aging filters, sort, chip rendering, and accessible labels. * [x] Manual testing completed for Trends and Signal Workbench surfaces through a local Workbench browser smoke plus rendered component coverage for the reusable Trend card. ### 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 | Uses existing Trend Finder terminology and descriptive names. | | File Structure | PASS | Script logic remains under `scripts/`; UI/model changes remain under `src/extensions/trend-finder/`; tests stay near covered behavior. | | Error Handling | PASS | Invalid half-life and date inputs fall back to bounded warnings or unavailable states. | | Comments | PASS | No obvious commented-out code or noisy comments. | | Testing | PASS | Focused tests cover scoring, source config, schema, view model, Workbench, and Trend card behavior. | ### 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/signal-aging.ts`, `scripts/lib/ai-runtime/scoring.ts`, `scripts/extensions/trend-finder/sources/apify-source-config.ts`, `src/extensions/trend-finder/schema.ts`, `src/extensions/trend-finder/components/signal-workbench-table.tsx` | Category | Status | File | Details | | ------------------ | ------ | ------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------- | | Trust boundaries | PASS | `apify-source-config.ts`, `schema.ts` | Env/file half-life metadata and browser payload fields are schema bounded. | | Resource cleanup | PASS | `signal-aging.ts`, `scoring.ts` | Pure deterministic helpers; no timers, subscriptions, connections, or acquired resources. | | Mutation safety | PASS | `signal-workbench-table.tsx` | New UI is read-only display/sort surface; no write path added. | | Failure paths | PASS | `signal-aging.ts`, `scoring.ts` | Invalid input maps to fallback recency, warnings, or explicit unavailable aging states. | | Contract alignment | PASS | `scoring.ts`, `schema.ts` | Scoring version bumped to `trend-finder-scoring-v28.5`, six-factor weights remain unchanged, legacy payloads default safely. | ### Violations Found None after validation fixes. ### Fixes Applied During Validation * Updated `scripts/lib/ai-runtime/__tests__/scoring-calibration.test.ts` to expect `trend-finder-scoring-v28.5`, matching the intentional scoring-version bump. * Added a visible Workbench `Age` sort column and row Age pill in `src/extensions/trend-finder/components/signal-workbench-table.tsx`, with coverage in `src/extensions/trend-finder/components/__tests__/trend-sparkline.test.tsx`. ## Validation Result ### PASS Session 05 is validated. All tasks are complete, deliverables exist, source and session files are ASCII/LF clean, tests and typechecks pass, browser smoke passed for the mounted Workbench surface, security/GDPR review is clean, and no DB-layer alignment work is applicable. ### Required Actions None. ## Next Steps Run `updateprd` to mark the 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/phase28-session05-signal-aging-half-lives-and-saturation-refinement/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.
