The planning file was absent when implementation started and must remain absent. Coverage is complete only when every source heading, numbered item, already-ahead area, non-goal, deferred candidate, and sequencing note maps to shipped manuals, Phase 28 PRD content, session specs, or an explicit no-action decision. This is a coverage artifact, not a recreated planning note. It summarizes destinations and decisions so the old note does not need to return. *** ## Source Status | Source | Status | Evidence | | ----------------------------------------- | ----------------------------------------------------------------- | ------------------------------------------------------------------------------------ | | `docs/ongoing-projects/trends-finderz.md` | Absent at implementation start and after manual/reference updates | Filesystem checks on 2026-06-14 | | Source anchors from retired planning note | Preserved | `.spec_system/PRD/phase_28/PRD_phase_28.md` overview artifact table | | Method, caveats, and invariants | Preserved | Phase 28 PRD overview, reconciliation notes, invariants, risks, and considerations | | Numbered item mapping | Preserved | `.spec_system/PRD/phase_28/session_01_*.md` through `session_15_*.md` | | Manuals and Reference mode | In current docs, updated during this session | `docs/extensions/trend-finder-*.md`, `src/extensions/trend-finder/reference-docs.ts` | *** ## Source Material And Anchors | Retired Planning Area | Durable Destination | Closeout Status | Notes | | ------------------------------------- | --------------------------------------------------------------- | --------------- | --------------------------------------------------------------------------------------------------------------------------------- | | Project overview | `.spec_system/PRD/phase_28/PRD_phase_28.md` artifact table | Covered | Preserves the Trends-Finderz README path and what it proves. | | Data model | Phase 28 PRD artifact table and explicit non-goals | Covered | PostgreSQL, Drizzle, pgvector, locks, and snapshots are recorded as source context, not ported storage shape. | | Signal quality layer | Session 01 and 02 PRD stubs, scoring and pipeline manuals | Covered | URL normalization, content hashes, fingerprints, quality scores, dedup counters, and coverage counters have durable destinations. | | Scoring layer | Session 03 through 06 PRD stubs and scoring manual | Covered | Calibration, dampening, saturation, visibility, aging, lifecycle multiplier, and named contributions are covered. | | Product QA layer | Session 07 and 08 PRD stubs, scoring/runtime manuals | Covered | Research-only calibration, action verdict QA, consistency checks, and retention posture are covered. | | Trend surfaces | Session 09 through 12 PRD stubs and UI surfaces manual | Covered | Action Queue, pins, notes, tags, palette search, Brief QA, Markdown export, and KPI strip are covered. | | Scan orchestration and keyword config | Session 13 PRD stub and sources/pipeline manuals | Covered | Scan modes, keyword packs, rotation, coverage QA, caps, and warnings are covered. | | Source connectors | Session 14 PRD stub, sources manual, and source compliance docs | Covered | Direct adapters and Apify fallback behavior are covered with compliance gates. | | Cron/retention | Session 07 PRD stub, pipeline manual, and explicit non-goals | Covered | Hosted cron and DB locks are non-goals;

sources manual; considerations | Covered | Candidate names are not approvals and require source-specific compliance review. | | SQLite observation store transition | Phase 28 PRD dependencies and explicit non-goals | Covered | May absorb retention, calibration stamps, and run history in a later phase. | | Standalone Action Queue route | Session 09 PRD/spec/validation and UI manual | Covered | Deferred unless the Brief decision section becomes cramped. | | Local embedding model, vector DB, or model download | ADR 0002 and runtime manual | Covered | Rejected for this phase; feature-hash vectors are the accepted implementation. | | Historical run selection in Engine Replay | docs/extensions/README\_docs-extensions.md and UI/runtime manuals | Covered | Depends on a future durable local run store. | | Hosted observability, production trace storage, generic replay | docs/extensions/README\_docs-extensions.md and runtime manual | Covered | Out of current local extension scope. | *** ## Sequencing Coverage | Tier | Sessions | Durable Destination | Closeout Status | Notes | | ---------------------------------------- | -------- | --------------------------------------------------------------------------- | --------------- | ------------------------------------------------------------------------------------ | | 1 - scoring integrity, no new surfaces | 01-03 | Phase 28 PRD tier table, session PRDs/specs | Covered | Completed before visibility, aging, action, and source changes. | | 2 - derived layers on existing data | 04-07 | Phase 28 PRD tier table, session PRDs/specs | Covered | Pure derivations plus private retention landed before decision/UI layers. | | 3 - decision layer and operator features | 08-12 | Phase 28 PRD tier table, session PRDs/specs | Covered | Product-visible features built on bounded derived fields and browser-local state. | | 4 - collection changes, compliance-gated | 13-14 | Phase 28 PRD tier table, sources manual, source compliance docs | Covered | Keyword inputs and direct adapters landed only with reviewed gates and spend labels. | | Closeout | 15 | This artifact, security report, validation report, manuals, PRDs, changelog | Covered | Documents, validates, security-reviews, and keeps the retired note absent. | *** ## Deletion Decision `docs/ongoing-projects/trends-finderz.md` was absent at implementation start. The durable coverage destinations above preserve the source anchors, method, caveats, item mapping, already-ahead areas, non-goals, deferred candidates, and sequencing that the retired planning note carried. The implementation decision is to keep the file absent and not recreate stale planning content. Final release validation must still confirm the file remains absent after all PRD, security, validation, and changelog updates are complete. --- # Agent Instructions This documentation is published with GitBook.
