Test Results ### Status: PASS | Metric | Value | | ----------- | ------------- | | Total Tests | 3507 | | Passed | 3507 | | Failed | 0 | | Coverage | Not collected | ### Commands Run * `bun run test` - PASS, 286 test files and 3507 tests passed * `bun run lint` - PASS * `bun run typecheck:scripts` - PASS * `bun run typecheck` - PASS * `git diff --check` - PASS * ASCII/LF scan - PASS, 31 files checked ### Failed Tests None after validation-time fixes. *** ## 5. Database/Schema Alignment ### Status: N/A *N/A because the session introduced no persisted data shape, database migration, database constraint, index, seed, ORM metadata, or DB-layer behavior change.* * [x] No DB-layer change detected * [x] No schema artifact required * [x] Application schema changes are Zod browser/script payload contracts only ### Issues Found N/A - no DB-layer changes. *** ## 6. Success Criteria From spec.md: ### Functional Requirements * [x] Every new snapshot records the current scoring version. * [x] Every new prediction record records the current scoring version at filing time. * [x] Legacy snapshots and predictions parse as `unknown` version without crashing. * [x] Movement comparisons across different or unknown scoring versions are flagged with provenance text and still return normal movement statuses. * [x] Retro comparisons across different or unknown scoring versions are flagged with provenance text and still preserve due-state behavior. * [x] Thin-evidence topics receive a bounded confidence adjustment; strong evidence topics are minimally affected. * [x] Score breakdown UI shows the sample-confidence value and dampener context alongside the existing factor rows. ### Testing Requirements * [x] Unit tests written and passing for confidence derivation, dampener clamps, and thin-vs-strong evidence behavior. * [x] Snapshot tests cover version stamping, default `unknown`, and comparison metadata. * [x] Movement and retro tests cover cross-version flagging without suppression. * [x] Prediction tests cover deterministic and sanitized AI-output stamping. * [x] Schema, view-model, and component tests cover legacy defaults and visible confidence/version labels. ### Quality Gates * [x] All files ASCII-encoded. * [x] Unix LF line endings. * [x] Code follows project conventions. * [x] Focused Vitest suites pass as part of full `bun run test`. * [x] `bun run typecheck:scripts` passes for script-side contracts touched in this session. *** ## 7. Conventions Compliance ### Status: PASS | Category | Status | Notes | | -------------- | ------ | ------------------------------------------------------------------------------------------------------------------------ | | Naming | PASS | New names match Trend Finder scoring, confidence, dampener, and provenance terminology. | | File Structure | PASS | Implementation and tests remain in existing Trend Finder script, model, component, and test locations. | | Error Handling | PASS | Invalid snapshot payloads produce bounded schema issue warnings; non-finite scoring inputs clamp to safe defaults. | | Comments | PASS | No commented-out code or unnecessary explanatory comments found. | | Testing | PASS | Full suite covers scoring, snapshot, movement, prediction, retro, collector, schema, view-model, and component behavior. | ### Convention Violations None remain. Prettier formatting issues found by `bun run lint` were fixed during validation and lint was rerun successfully. *** ## 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 *Application code was produced, so BQC applies.* **Checklist applied**: Yes **Files spot-checked**: `scripts/lib/ai-runtime/scoring.ts`, `scripts/extensions/trend-finder/collector.ts`, `scripts/lib/ai-runtime/movement-analyst.ts`, `scripts/lib/ai-runtime/predictions.ts`, `src/extensions/trend-finder/schema.ts` | Category | Status | File | Details | | ------------------ | ------ | ---------------------------------------------- | ------------------------------------------------------------------------------------------------------------------- | | Trust boundaries | PASS | `scripts/lib/ai-runtime/predictions.ts` | Prediction scoring version is stamped locally and AI output attempting to set provenance is rejected. | | Resource cleanup | PASS | `scripts/extensions/trend-finder/collector.ts` | No new timers, subscriptions, connections, or retained resources were added. | | Mutation safety | PASS | `scripts/lib/ai-runtime/scoring.ts` | Confidence math is deterministic and bounded; it cannot inflate low-confidence scores above the raw weighted score. | | Failure paths | PASS | `scripts/lib/ai-runtime/scoring.ts` | Non-finite and negative confidence inputs normalize to bounded safe defaults. | | Contract alignment | PASS | `src/extensions/trend-finder/schema.ts` | Additive defaults preserve legacy payload, snapshot, prediction, retro, story-log, and summary parsing. | ### Violations Found None. ### Fixes Applied During Validation * Updated `scripts/lib/ai-runtime/__tests__/scoring.test.ts` so legacy scoring assertions validate the new raw weighted score and adjusted score contract. * Applied ESLint/Prettier fixes to touched implementation files after lint reported formatting-only issues. ## Validation Result ### PASS Session 03 satisfies the task checklist, deliverables, quality gates, security/GDPR review, and behavioral quality spot-check. Validation-time fixes were rechecked with the focused scoring suite, the full Vitest suite, lint, both typechecks, diff whitespace validation, and ASCII/LF checks. ### 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/phase28-session03-calibration-version-and-confidence-dampener/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.
