ASCII Encoding Check ### Status: PASS | Scope | Encoding | Line Endings | Status | | --------------------------- | -------- | ------------ | ------ | | Changed and untracked files | ASCII | LF | PASS | ### Encoding Issues None. *** ## 4. Test Results ### Status: PASS | Metric | Value | | ----------- | --------------------------------- | | Total Tests | 3,734 | | Passed | 3,734 | | Failed | 0 | | Coverage | Not measured in this validate run | ### Commands * `bun run test` - PASS, 317 test files and 3,734 tests. * `bun run typecheck` - PASS. * `bun run typecheck:scripts` - PASS. * `bun run lint` - PASS. * `bunx prettier --check ...session source/test/doc files...` - PASS. * `bun run scripts/extensions/trend-finder/measure-payload-size.ts src/data/live-data.example.json --all --json` - PASS, Trend Finder browser data payload 14,138 bytes under the 1,048,576 byte extension boundary. ### Failed Tests None in the final run. ### Validation Fixes Applied * `scripts/lib/ai-runtime/action-consistency.ts` now uses `TREND_TOPIC_RISK_FLAGS` so `originator-only` is accepted by action consistency QA. * `scripts/lib/ai-runtime/__tests__/scoring-calibration.test.ts` now expects the neutral `corroboration_gate` score adjustment row in the ordered adjustment list. *** ## 5. Database/Schema Alignment ### Status: N/A *N/A because this session introduced no DB-layer changes.* * [x] No migration was required. * [x] No database schema artifact was required. * [x] Runtime Zod schema changes were covered by schema tests. * [x] No seed or rollback update was required. ### Issues Found N/A - no DB-layer changes. *** ## 6. Success Criteria From `spec.md`: ### Functional Requirements * [x] `corroboration` defaults to an explicit unavailable state for legacy payloads. * [x] A fixture dominated by one reviewed entity is flagged `originator-only`, down-weighted, and blocked from `act_now`. * [x] A multi-entity independent fixture stays confirmed and is not down-weighted by the corroboration gate. * [x] `originator-only` is reported distinctly from `single-source-signal`; a topic can have one, both, or neither. * [x] Live and static surfaces show concise corroboration labels without raw entity IDs or private identity details. ### Testing Requirements * [x] Unit tests written and passing for corroboration derivation, source-breakdown wiring, scoring adjustment, and action caps. * [x] Schema/view-model/component tests cover legacy defaults, labels, tones, accessibility labels, and long text safety. * [x] Static Brief export/renderer tests cover projected corroboration cells and privacy scan behavior. * [x] Payload-size check confirms the extension remains under the 1 MB boundary. * [x] Focused and full test commands recorded in implementation notes and this validation report. ### Quality Gates * [x] All files ASCII-encoded. * [x] Unix LF line endings. * [x] Code follows project conventions. * [x] New enum branches use exhaustive handling and explicit fallback behavior. *** ## 7. Conventions Compliance ### Status: PASS | Category | Status | Notes | | -------------- | ------ | --------------------------------------------------------------------------------------------------------------------------------- | | Naming | PASS | New corroboration, risk flag, action cap, and score adjustment names are descriptive and match existing Trend Finder terminology. | | File Structure | PASS | Runtime helpers, tests, component tests, static Brief tests, and docs are in established local locations. | | Error Handling | PASS | Zod parsing, explicit unavailable defaults, bounded text, and safe fallbacks are used at trust boundaries. | | Comments | PASS | No commented-out code or noisy comments found in the reviewed changes. | | Testing | PASS | Focused runtime, schema, view-model, component, static Brief, and collector/scoring calibration tests cover the changed behavior. | ### Convention Violations None. ### Formatting Note The full repo `bun run format:check` command reported existing `.spec_system` markdown formatting warnings. Session source, test, and public docs passed targeted Prettier after validation fixes, and full lint passed. *** ## 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/corroboration.ts` * `scripts/lib/ai-runtime/source-breakdown.ts` * `scripts/lib/ai-runtime/scoring.ts` * `scripts/lib/ai-runtime/action-priority.ts` * `scripts/extensions/trend-finder/static-brief-renderer.ts` | Category | Status | File | Details | | ------------------ | ------ | -------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------ | | Trust boundaries | PASS | `scripts/lib/ai-runtime/corroboration.ts` | Input is schema parsed, invalid evidence is ignored, and output is parsed through the schema. | | Resource cleanup | PASS | `scripts/lib/ai-runtime/source-breakdown.ts` | No timers, subscriptions, file handles, network calls, or persistent resources are acquired. | | Mutation safety | PASS | `scripts/lib/ai-runtime/source-breakdown.ts` | Risk flags are merged through a set and emitted in schema order, preventing duplicate `originator-only` flags. | | Failure paths | PASS | `scripts/lib/ai-runtime/scoring.ts` | Non-originator states produce neutral corroboration adjustments; unavailable identity data falls back explicitly. | | Contract alignment | PASS | `scripts/lib/ai-runtime/action-priority.ts` | Action priority blocks originator-only topics from `act_now`, and action consistency now accepts the canonical risk flag list. | ### Violations Found None. ### Fixes Applied During Validation * Added canonical risk flag parsing to `scripts/lib/ai-runtime/action-consistency.ts`. * Updated `scripts/lib/ai-runtime/__tests__/scoring-calibration.test.ts` for the new `corroboration_gate` adjustment row. ## Validation Result ### PASS Session 04 satisfies task completion, deliverable, encoding, test, runtime schema, security, GDPR, and behavioral quality validation checks. The only blockers found during validation were fixed and re-tested. ### 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-session04-corroboration-gate/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.
