Run focused validation **Started**: 2026-06-14 03:49 **Completed**: 2026-06-14 04:00 **Duration**: 11 minutes **Notes**: * Ran the combined focused Vitest set for scoring calibration, snapshots, movement, predictions, retros, collector, schema, ScoreBreakdown, Engine Replay, and dashboard coverage. * Ran script and app TypeScript checks. * Ran ASCII/LF validation across changed and new session artifacts. * All checks passed. **Verification**: * `bunx vitest run scripts/lib/ai-runtime/__tests__/scoring-calibration.test.ts scripts/lib/ai-runtime/__tests__/snapshots.test.ts scripts/lib/ai-runtime/__tests__/movement-analyst.test.ts scripts/lib/ai-runtime/__tests__/predictions.test.ts scripts/lib/ai-runtime/__tests__/retros.test.ts scripts/extensions/trend-finder/__tests__/collector.test.ts src/lib/__tests__/trend-finder-schema.test.ts src/extensions/trend-finder/components/__tests__/score-breakdown.test.tsx src/lib/__tests__/trend-finder-engine-replay.test.tsx src/lib/__tests__/trend-finder-dashboard.test.tsx` - 10 files, 280 tests passed. * `bun run typecheck:scripts` - passed. * `bun run typecheck` - passed. * ASCII/LF validation - passed. **Files Changed**: * `.spec_system/specs/phase28-session03-calibration-version-and-confidence-dampener/tasks.md` - marked T023 complete and checked the completion checklist. * `.spec_system/specs/phase28-session03-calibration-version-and-confidence-dampener/implementation-notes.md` - recorded final validation. **BQC Fixes**: * Regression prevention: final focused validation covers runtime logic, archive parsing, collector payloads, and browser rendering for the new calibration/version metadata. **Validation Follow-up**: * During the validate workflow, full `bun run test` exposed stale assertions in `scripts/lib/ai-runtime/__tests__/scoring.test.ts` that still expected final `score` to equal the raw six-factor score. * Updated those assertions to verify `rawOpportunityScore`, adjusted `score`, sample confidence, and dampener metadata under the new calibration contract. * Applied formatting fixes reported by `bun run lint` and re-ran the full validation command set successfully. *** ### Task T022 - Add browser-facing collector, schema, view-model, and component tests **Started**: 2026-06-14 03:40 **Completed**: 2026-06-14 03:49 **Duration**: 9 minutes **Notes**: * Added collector assertions for browser payload and topic scoring-version stamping, scoring trace metadata, and prediction-retro summary version metadata. * Added schema tests for legacy `unknown` scoring-version defaults on payloads, topics, predictions, and retros. * Added view-model assertions for sample-confidence labels and scoring-version mismatch labels. * Added ScoreBreakdown rendering coverage for sample-confidence and dampener context. * Added Engine Replay coverage for bounded scoring-version provenance display without private paths. * Updated an existing one-evidence watchlist expectation from hidden-gem to rising-delta because confidence dampening now lowers that thin sample below the hidden-gem threshold. * Verified with `bunx vitest run scripts/extensions/trend-finder/__tests__/collector.test.ts src/lib/__tests__/trend-finder-schema.test.ts src/extensions/trend-finder/components/__tests__/score-breakdown.test.tsx src/lib/__tests__/trend-finder-engine-replay.test.tsx`. **Files Changed**: * `scripts/extensions/trend-finder/__tests__/collector.test.ts` -

added retro version fields, sanitizer preservation, local comparison derivation, prompt context, and AI override guard. * `.spec_system/specs/phase28-session03-calibration-version-and-confidence-dampener/tasks.md` - marked T014 complete and updated progress. * `.spec_system/specs/phase28-session03-calibration-version-and-confidence-dampener/implementation-notes.md` - recorded retro implementation and verification. **BQC Fixes**: * Trust boundary enforcement: retro scoring-version provenance is locally derived and AI-provided fields are rejected. * Contract alignment: due-state/outcome behavior remains separate from scoring-version comparison metadata. *** ### Task T013 - Flag movement cross-version comparisons **Started**: 2026-06-14 02:52 **Completed**: 2026-06-14 02:55 **Duration**: 3 minutes **Notes**: * Confirmed movement status and evidence diff logic remains independent of scoring-version comparison state. * Movement records now carry local comparison metadata that flags `unknown` and `mismatch` states without suppressing movement rows. * Added an explicit movement-analyst instruction that scoring-version comparison provenance is assigned locally. * Verified with `bun run typecheck:scripts`. **Files Changed**: * `scripts/lib/ai-runtime/movement-analyst.ts` - added explicit AI instruction and retained local comparison flagging behavior. * `.spec_system/specs/phase28-session03-calibration-version-and-confidence-dampener/tasks.md` - marked T013 complete and updated progress. * `.spec_system/specs/phase28-session03-calibration-version-and-confidence-dampener/implementation-notes.md` -

Extend snapshot scoring-version contracts **Started**: 2026-06-14 02:19 **Completed**: 2026-06-14 02:24 **Duration**: 5 minutes **Notes**: * Added top-level snapshot `scoringVersion` parsing with `unknown` legacy defaults. * Added scoring-version and comparison metadata to snapshot comparison output while preserving existing movement status derivation. * Stamped new snapshot writes with the local `SCORING_VERSION` and inherited that value into topics that omit their own version. * Preserved legacy reads as `unknown`; only write paths stamp the current local version. * Verified with `bun run typecheck:scripts`. **Files Changed**: * `scripts/lib/ai-runtime/snapshots.ts` - added snapshot version schema, write-time stamping, comparison metadata, and additive type wrappers. * `.spec_system/specs/phase28-session03-calibration-version-and-confidence-dampener/tasks.md` - marked T006 complete and updated progress. * `.spec_system/specs/phase28-session03-calibration-version-and-confidence-dampener/implementation-notes.md` - recorded snapshot implementation and verification. **BQC Fixes**: * State freshness on re-entry: archived snapshots keep their parsed version provenance, and only newly written snapshots receive the current local version. *** ### Task T005 - Add additive scoring-version schemas **Started**: 2026-06-14 02:12 **Completed**: 2026-06-14 02:19 **Duration**: 7 minutes **Notes**: * Added browser/shared schema constants for `unknown` scoring versions and `current`, `mismatch`, and `unknown` comparison states. * Added reusable scoring-version value and comparison schemas with bounded strings and legacy defaults. * Added additive metadata to topic, movement, prediction, retro, story-log, prediction-retro summary, and top-level Trend Finder payload schemas. * Kept exported TypeScript types additive-compatible where existing fixtures construct objects manually; Zod parse output still receives concrete defaults. * Ran `bun run typecheck:scripts`; remaining failures are downstream snapshot/write-path contract assignments expected to be resolved by T006 and collector wiring. **Files Changed**: * `src/extensions/trend-finder/schema.ts` - added scoring-version, confidence metadata, comparison schemas, and additive exported type wrappers. * `.spec_system/specs/phase28-session03-calibration-version-and-confidence-dampener/tasks.md` - marked T005 complete and updated progress. * `.spec_system/specs/phase28-session03-calibration-version-and-confidence-dampener/implementation-notes.md` -

Define scoring version and calibration helpers **Started**: 2026-06-14 02:10 **Completed**: 2026-06-14 02:12 **Duration**: 2 minutes **Notes**: * Added `SCORING_VERSION`, `UNKNOWN_SCORING_VERSION`, and bounded comparison metadata helpers in `scripts/lib/ai-runtime/scoring.ts`. * Added pure sample-confidence derivation from evidence count, distinct scoring source count, and scoring-evidence share. * Added bounded confidence dampener helper with a 0.62 floor, finite-number guards, rounded multiplier metadata, and no adjusted-score inflation above the raw score. **Files Changed**: * `scripts/lib/ai-runtime/scoring.ts` - added scoring version and confidence calibration helpers. * `.spec_system/specs/phase28-session03-calibration-version-and-confidence-dampener/tasks.md` - marked T004 complete and updated progress. * `.spec_system/specs/phase28-session03-calibration-version-and-confidence-dampener/implementation-notes.md` - recorded helper implementation. **BQC Fixes**: * Failure path completeness: pure helpers normalize non-finite and negative numeric input to bounded safe defaults. *** ### Task T003 - Inspect current Trend Finder contracts **Started**: 2026-06-14 02:03 **Completed**: 2026-06-14 02:10 **Duration**: 7 minutes **Notes**: * Reviewed scoring contracts in `scripts/lib/ai-runtime/scoring.ts`; the current final `score` comes directly from the six-factor weighted score and feeds movement, hidden-gem, trajectory, and ranking behavior. * Reviewed snapshot, prediction, retro, and movement modules; archive schemas parse additive records through shared browser Zod schemas, and AI output is sanitized before persistence. * Reviewed collector orchestration; previous snapshots are projected into scoring and movement inputs, while prediction/retro records are archived and projected into browser-safe story-log rows. * Reviewed schema, view-model, score-breakdown, and Engine Replay score rendering; all current UI score context is topic-driven and schema-defaulted. **Files Changed**: * `.spec_system/specs/phase28-session03-calibration-version-and-confidence-dampener/tasks.md` - marked T003 complete and updated progress. * `.spec_system/specs/phase28-session03-calibration-version-and-confidence-dampener/implementation-notes.md` - recorded contract inspection. **BQC Fixes**: * None. *** ### Task T002 - Inspect Trends-Finderz scoring reference **Started**: 2026-06-14 02:02 **Completed**: 2026-06-14 02:03 **Duration**: 1 minute **Notes**: * Reviewed `EXAMPLES/trends-finderz/lib/scoring/trend-score.ts`; it keeps factor math separate from confidence damping. * Reviewed `EXAMPLES/trends-finderz/lib/scoring/score-utils.ts`; the reusable pattern clamps finite scores and applies `floor + (1 - floor) * confidence` with a 0.62 floor. * Local adaptation should preserve the current six-factor weights, compute confidence from existing evidence metadata, and prevent confidence from inflating scores. **Files Changed**: * `.spec_system/specs/phase28-session03-calibration-version-and-confidence-dampener/tasks.md` - marked T002 complete and updated progress. * `.spec_system/specs/phase28-session03-calibration-version-and-confidence-dampener/implementation-notes.md` - recorded scoring reference review. **BQC Fixes**: * None. *** ### Task T001 -

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.
