ASCII Encoding Check ### Status: PASS | Scope | Encoding | Line Endings | Status | | ------------------------------------ | -------- | ------------ | ------ | | Modified and untracked session files | ASCII | LF | PASS | ### Encoding Issues None. *** ## 4. Test Results ### Status: PASS | Metric | Value | | ----------- | ------- | | Total Tests | 3551 | | Passed | 3551 | | Failed | 0 | | Coverage | Not run | ### Commands * `bun run test` - PASS, 291 files and 3551 tests. * `bun run typecheck` - PASS. * `bun run typecheck:scripts` - PASS. * `bun run lint` - PASS. * `bunx prettier --check` over modified and untracked session files - PASS. * ASCII and CRLF scan over modified and untracked session files - PASS. * Independent `bun --eval` smoke for chip projection, Workbench risk filter/facet, and temp archive retention pruning - PASS. ### Failed Tests None. *** ## 5. Database/Schema Alignment ### Status: N/A N/A - this session introduced no DB-layer changes, migrations, persisted database schema, constraints, indexes, seeds, or ORM metadata. ### Issues Found N/A - no DB-layer changes. *** ## 6. Success Criteria From `spec.md`: ### Functional Requirements * [x] A topic supported only by research-role evidence is flagged `research-only`. * [x] A topic with developer, discussion, or launch adoption evidence is not flagged `research-only` even when research evidence is also present. * [x] `research-only` appears as a bounded Trend card chip and as a Signal Workbench risk flag filter. * [x] Legacy payloads parse when they omit the new flag, and invalid flag data still falls back safely. * [x] Snapshot, prediction, and retro archives prune dated JSON files beyond a clamped retention window while preserving `latest.json`. * [x] The retention pass respects the 84-day history window, reviewed backtest windows, and active Creator Lens state. * [x] Collector trace and warnings report per-store counts and sanitized codes only; no private file paths enter browser payloads. * [x] Existing risk flag, scoring, history, prediction, retro, collector, and UI tests continue to pass. ### Testing Requirements * [x] Unit tests written and passing for role-composition risk derivation, flag ordering, malformed inputs, and adoption-role exclusions. * [x] Scoring integration tests cover research-only payload output alongside existing risk flags. * [x] Schema, view-model, and Workbench tests cover additive parsing, chip copy, facet counts, and filter behavior. * [x] Snapshot, prediction, and retro archive tests cover retention clamps, latest preservation, deletion counts, malformed files, and path safety. * [x] Collector tests cover end-of-collect retention invocation, trace counts, warning behavior, and no private path leakage. * [x] Manual smoke completed for Trend card risk chips, Signal Workbench risk flag filter, and temp cache retention pruning. ### Quality Gates * [x] All session files ASCII-encoded. * [x] Unix LF line endings. * [x] Code follows project conventions. * [x] Focused and full tests pass. *** ## 7. Conventions Compliance ### Status: PASS | Category | Status | Notes | | -------------- | ------ | --------------------------------------------------------------------------------------- | | Naming | PASS | New names follow existing Trend Finder risk flag, retention, and Workbench conventions. | | File Structure | PASS | Runtime helpers, tests, UI, and docs stay in established directories. | | Error Handling | PASS | Retention failures are bounded to warning codes and counts. | | Comments | PASS | No commented-out code or unnecessary comments found. | | Testing | PASS | Focused tests added near changed behavior 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 | PASS | 0 issues | ### Critical Violations None. *** ## 9. Behavioral Quality Spot-Check ### Status: PASS **Checklist applied**: Yes **Files spot-checked**: `scripts/lib/ai-runtime/risk-flags.ts`, `scripts/lib/ai-runtime/snapshots.ts`, `scripts/lib/ai-runtime/predictions.ts`, `scripts/lib/ai-runtime/retros.ts`, `scripts/extensions/trend-finder/collector.ts` | Category | Status | File | Details | | ------------------ | ------ | ---------------------------------------------- | -------------------------------------------------------------------------------- | | Trust boundaries | PASS | `scripts/lib/ai-runtime/risk-flags.ts` | Role-composition input is schema-validated and bounded. | | Resource cleanup | PASS | `scripts/lib/ai-runtime/snapshots.ts` | Archive pruning asserts path containment before deletion. | | Mutation safety | PASS | `scripts/extensions/trend-finder/collector.ts` | Retention runs once per collect run after writes. | | Failure paths | PASS | `scripts/extensions/trend-finder/collector.ts` | Store failures and warning summaries are surfaced as bounded warning codes. | | Contract alignment | PASS | `src/extensions/trend-finder/schema.ts` | `research-only` extends the existing `riskFlags` array with legacy-safe parsing. | ### Violations Found None. ### Fixes Applied During Validation * Updated two visibility/dashboard test expectations after the fixture gained `topic-006` and an extra active research source. * Hardened snapshot, prediction, and retro archive date parsing so invalid calendar dates such as `2026-99-99...json` are preserved as unclassified instead of being rolled into a valid JavaScript date. ## Validation Result ### PASS All session tasks are complete, all deliverables exist, full tests pass, quality checks pass for the session scope, and no security, GDPR, DB/schema, or behavioral-quality blockers remain. ### 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-session07-research-only-calibration-and-cache-retention/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.
