It is a release record, not a second feature plan. *** ## Coverage Matrix ### Session Coverage | Session | Closeout status | Durable destination | Notes | | --------------------------------------- | ---------------- | ---------------------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------- | | 01 Editorial Quick Wins | Shipped | `docs/extensions/trend-finder-sources.md`, `docs/extensions/trend-finder-scoring.md`, Phase 29 PRD | Anti-AI-trope and tutorial-hype guardrails are shipped; broader social reach remains a non-goal. | | 02 Attention Pattern And Polarity Grid | Shipped | `docs/extensions/trend-finder-scoring.md`, `docs/extensions/trend-finder-ui-surfaces.md` | `attentionPattern` and polarity/attention presentation are shipped as bounded derived display fields. | | 03 Reception Signal Aggregate-Only | Shipped | `docs/extensions/trend-finder-scoring.md`, `docs/extensions/trend-finder-ui-surfaces.md` | Aggregate-only `receptionSignal` is shipped; comment bodies remain out of scope. | | 04 Corroboration Gate | Shipped | `docs/extensions/trend-finder-scoring.md`, `docs/extensions/trend-finder-pipeline.md` | `corroboration` separates independent-origin support from source count. | | 05 Per-Evidence Rationale | Shipped | `docs/extensions/trend-finder-scoring.md`, `docs/extensions/trend-finder-ui-surfaces.md` | Bounded per-evidence rationale copy is shipped; weak evidence can be omitted from topic rendering. | | 06 Cross-Topic Substrate Narratives | Shipped | `docs/extensions/trend-finder-pipeline.md`, `docs/extensions/trend-finder-runtime-and-provenance.md` | Run narratives cite known topic and evidence IDs or degrade to deterministic fallback. | | 07 Per-Stage Validation Narration | Shipped | `docs/extensions/trend-finder-pipeline.md`, `docs/extensions/trend-finder-runtime-and-provenance.md` | Retry-once-then-degrade stage narration appears only as sanitized Engine Replay rows. | | 08 Required-Derived-Field Closeout Gate | Shipped | `docs/extensions/trend-finder-pipeline.md`, `docs/extensions/trend-finder-ui-surfaces.md` | Generated payload and static Brief export reject missing required derived branches. | | 09 Source-Death Baseline Alarm | Shipped | `docs/extensions/trend-finder-pipeline.md`, `docs/extensions/trend-finder-sources.md` | Private last-good accepted-evidence baselines produce browser-safe alarm labels only. | | 10 Seed-Candidate Review Artifact | Shipped | `docs/extensions/trend-finder-runtime-and-provenance.md`, Phase 29 PRD | Private seed review remains a local compliance/debug artifact, not a source approval. | | 11 Industry-Events Rollup | Shipped | `docs/extensions/trend-finder-pipeline.md`, `docs/extensions/trend-finder-ui-surfaces.md` | Current-source event rows require at least two independent publisher identities. | | 12 Security Lens | Shipped | `docs/extensions/trend-finder-pipeline.md`, `docs/extensions/trend-finder-ui-surfaces.md` | Security relevance uses existing evidence and reviewed security keywords only. | | 13 Static Brief Archival And Richness | Shipped | `docs/extensions/trend-finder-pipeline.md`, `docs/extensions/trend-finder-ui-surfaces.md` | Static Brief archive and richer report projection stay local, private-cache, and no-media-embed by default. | | 14 One-To-Watch Surface | Shipped | `docs/extensions/trend-finder-pipeline.md`, `docs/extensions/trend-finder-ui-surfaces.md` | One to Watch is projected from existing prediction, retro, calibration, and topic fields. | | 15 Pre-Run Estimate | Shipped | `docs/extensions/trend-finder-pipeline.md`, `docs/extensions/trend-finder-ui-surfaces.md` | Pre-run estimate is planning transparency, not an enforced spend cap. | | 16 Podcast Compliance Package | Shipped decision | `docs/extensions/trend-finder-sources.md`, `docs/sources/source-compliance-podcasts.md` | Decision is `Defer`; podcast/audio implementation is not approved in Phase 29. | | 17 Podcast Themes Enrichment | Deferred | `session_17_podcast_themes_enrichment.md`, `docs/extensions/trend-finder-sources.md` | Skipped because Session 16 deferred the source/media boundary. | | 18 Documentation Validation And Release | Implemented | This artifact, `validation.md`, `security-compliance.md`, PRD, changelog | Closeout updates docs, release evidence, and spec-system records only. | ### Folded Comparison Backlog Coverage | Backlog item | Phase 29 status | Durable destination | | ------------------------------------ | ---------------------------------------------------- | ----------------------------------------- | | 1.1 Reception / sentiment layer | Shipped as aggregate-only reception | Scoring, UI surfaces, PRD coverage audit | | 1.2 Sentiment/polarity heat grid | Shipped as polarity/attention/reception presentation | UI surfaces, scoring | | 1.3 Cross-source corroboration gate | Shipped | Scoring, pipeline | | 1.4 Editorial verdict vocabulary | Shipped as deterministic attention pattern | Scoring, UI surfaces | | 1.5 Tutorial-hype noise detection | Shipped through existing quality/noise scoring | Scoring | | 1.6 Anti-AI-trope copy discipline | Shipped in analyst and fallback copy boundaries | Runtime/provenance, scoring | | 1.7 Per-evidence "why this item" | Shipped as bounded evidence rationale | Scoring, UI surfaces | | 1.8 Cross-topic substrate narratives | Shipped as bounded run narratives | Pipeline, runtime/provenance | | 2.1 Podcast themes | Deferred | Sources manual and podcast compliance doc | | 2.2 Industry-news extraction | Shipped from current RSS/Google News evidence only | Pipeline, UI surfaces | | 2.3 Security lens | Shipped from existing evidence only | Pipeline, UI surfaces | | 2.4 Social reach | Non-goal | Sources manual and PRD | | 2.5 Reply-driven seed discovery | Shipped as private review artifact only | Runtime/provenance and PRD | | T3 run numbering/archive | Shipped for static Brief artifacts | Pipeline, UI surfaces | | T3 per-stage validation narration | Shipped | Pipeline, runtime/provenance | | T3 staleness/field gate | Shipped | Pipeline, UI surfaces | | T3 One to Watch surface | Shipped | Pipeline, UI surfaces | | T3 pre-run estimate | Shipped | Pipeline, UI surfaces | | T3 single-artifact richness | Shipped without media embeds | UI surfaces, pipeline | | T3 source-death baseline | Shipped with private baseline only | Pipeline, sources | ### Explicit Deferrals And Non-Goals | Item | Release posture | Required future gate | | ----------------------------------------------------------- | -------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------- | | Podcast/audio themes | Deferred by Session 16; Session 17 skipped in Phase 29. | New source-specific compliance review approving provider, media rights, cache, retention, attribution, spend, parser fixtures, and leak tests. | | Broader social reach: X/Twitter, TikTok, Instagram, Bluesky | Deliberate non-goal under current API, terms, PII, and compliance posture. | Source-specific terms/API/PII/retention/parser/spend/browser-safety review before any source row or collector exists. | | Retired standalone comparison/opportunities planning docs | Remain retired. | Use Phase 29 PRD, session stubs, closeout coverage, and manuals as durable destinations. | | New runtime/schema/source behavior in Session 18 | Out of scope. | Future implementation session with spec, tests, docs, and compliance review. | *** ## Do-Not-Regress Guardrails | Guardrail | Closeout check | | ------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | History and memory | Docs preserve snapshots, daily series, 12-week history, topic identity, predictions, retros, calibration, Story Log, and private archive retention. | | Calibration honesty | Docs keep hit rate/Brier score context and avoid per-row mock accuracy claims. | | Provenance and privacy boundary | Manuals and tests keep raw prompts, provider responses, raw rows, logs, private paths, transcripts, media, account auth, and token-shaped strings out of browser/static output. | | Scoring rigor | Manuals preserve six score factors, bounded post-factor adjustments, capped support, unavailable states, and no-invented-metrics rules. | | Compliance-first sourcing | Source candidates stay gated; podcast/audio and broader social reach remain non-shipped. | | Operational surfaces | Docs preserve scheduler, run control, Source Setup, Workbench, MCP, Engine Replay, Reference mode, and static Brief boundaries. | | Browser payload budget | Release validation must record payload/bundle budget check result. | | Private artifacts | Release validation must record private-artifact scan result and keep generated outputs ignored/untracked. | *** ## Release Validation Bundle | Check | Command or review | Status | | -------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------- | | Reference docs and phrase checks | `bun run test -- src/extensions/trend-finder/__tests__/reference-docs.test.ts` | PASS | | Typecheck | `bun run typecheck` | PASS | | Script typecheck | `bun run typecheck:scripts` | PASS | | Full Vitest | `bun run test` | PASS | | Scoped formatting | `bun run prettier -- --check ` | PASS | | Static Brief export | `bun run trend-finder:export-brief -- --dry-run --json` | PASS | | Private artifact scan | `bun run runtime:check-private` | PASS | | Payload/bundle budget | `bun run build`, Trend Finder payload-size script, and `bun run budget:check` | PASS for build and Trend Finder payload; WARN for known pre-existing full bundle overage | | Dependency audit | `bun audit` | PASS | | Playwright e2e | `bun run test:e2e -- tests/e2e/trend-finder.spec.ts tests/e2e/trend-finder-engine-replay.spec.ts tests/e2e/trend-finder-static-brief.spec.ts tests/e2e/trend-finder-release-hardening.spec.ts` | PASS | | Manual closeout review | Docs/PRD/security/changelog review for planned-feature drift | PASS | *** ## Handoff Session implementation is ready for the validate workflow step. The release handoff is `validation.md`, `security-compliance.md`, cumulative `SECURITY-COMPLIANCE.md`, cumulative `CONSIDERATIONS.md`, Phase 29 PRD records, Trend Finder manuals, Reference mode tests, and changelog. --- # Agent Instructions This documentation is published with GitBook.
