Session Start **Environment verified**: * [x] Prerequisites confirmed * [x] Tools available through repo-local `node_modules/.bin` * [x] Directory structure ready *** ### Task T001 - Verify prerequisites and dependency boundary **Started**: 2026-06-14 11:39 **Completed**: 2026-06-14 11:40 **Duration**: 1 minute **Notes**: * Confirmed current session from `.spec_system/state.json` analysis. * Confirmed Phase 27 Session 11 and Phase 28 Session 10 are listed as completed. * Reviewed ADR 0002 and the Session 11 PRD scope; this session must resolve embeddings without adding a model dependency, vector database, source adapter, or published vector arrays. * Reran tool prereqs with `node_modules/.bin` in `PATH` to confirm Bun, TypeScript, Vitest, and Playwright are available. **Files Changed**: * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/implementation-notes.md` - Initialized session notes. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/tasks.md` - Marked prerequisite verification complete. *** ### Task T002 - Inspect Trends-Finderz vector reference **Started**: 2026-06-14 11:40 **Completed**: 2026-06-14 11:41 **Duration**: 1 minute **Notes**: * Reviewed `EXAMPLES/trends-finderz/lib/search/semantic-vector.ts`. * Portable concepts: bounded 384-dimension vectors, text normalization, stopword filtering, synonym expansion, soft stems, bigrams, trigrams, character 4-grams, signed SHA-256 feature hashing, and L2 normalization. * Non-portable concepts: direct `node:crypto` use for browser code and `toPgVectorLiteral`, which is tied to persistence that this session explicitly avoids. **Files Changed**: * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/implementation-notes.md` - Logged reference mapping. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/tasks.md` - Marked reference inspection complete. *** ### Task T003 - Confirm palette targets, hash navigation, and payload safety **Started**: 2026-06-14 11:41 **Completed**: 2026-06-14 11:42 **Duration**: 1 minute **Notes**: * Confirmed extension routes use `/extensions/$extensionId/$viewId`. * Confirmed Trends view reads `#topic:` and selects matching topic or canonical topic IDs. * Confirmed ranked topic cards expose `id="topic:"`, so hash navigation can target existing DOM anchors. * Confirmed search documents must be projected from parsed Trend Finder payload strings only; raw payloads, private paths, provider responses, prompts, credentials, and vector arrays stay out of browser data. **Files Changed**: * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/implementation-notes.md` - Logged navigation and payload boundary findings. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/tasks.md` - Marked integration target inspection complete. *** ### Task T004 - Create shared text feature and lexical scoring primitives **Started**: 2026-06-14 11:42 **Completed**: 2026-06-14 11:47 **Duration**: 5 minutes **Notes**: * Added dependency-free shared text normalization, stopword filtering, synonym expansion, soft stems, n-gram features, vector contracts, cosine math, and hybrid lexical/cosine score composition. * Kept hashing out of the shared file so browser and script callers can supply environment-appropriate SHA-256 implementations. **Files Changed**: * `src/lib/trend-text-vector-features.ts` - Added shared feature extraction, lexical scoring, vector normalization, cosine, and hybrid scoring helpers. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/implementation-notes.md` - Logged shared vector primitive work. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/tasks.md` - Marked shared primitive task complete. **BQC Fixes**: * Contract alignment: Kept shared helpers free of Node-only imports so they can be used by browser code without bundle drift. *** ### Task T005 - Create script-side SHA-256 vectors and grouping helpers **Started**: 2026-06-14 11:42 **Completed**: 2026-06-14 11:48 **Duration**: 6 minutes **Notes**: * Added Node `crypto` signed feature hashing over the shared feature stream. * Added deterministic ranking and greedy similarity grouping with bounded group counts, bounded group size, thresholds, stable tie-breakers, and fallback-safe empty vectors. **Files Changed**: * `scripts/lib/ai-runtime/text-vectors.ts` - Added script vector creation, cosine similarity, hybrid ranking, and similarity grouping helpers. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/implementation-notes.md` - Logged script vector work. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/tasks.md` - Marked script vector task complete. **BQC Fixes**: * Failure path completeness: Empty or non-tokenizable text returns an all-zero vector and grouping filters it out instead of throwing. * Contract alignment: Grouping outputs IDs and display labels only, not vectors. *** ### Task T006 - Create browser Web Crypto vector helper **Started**: 2026-06-14 11:42 **Completed**: 2026-06-14 11:49 **Duration**: 7 minutes **Notes**: * Added browser-only Web Crypto SHA-256 feature hashing with no Node imports. * Added async ranking over already-loaded text documents with a lexical fallback if Web Crypto is missing, vector ranking fails, times out, or the caller reports a stale query. **Files Changed**: * `src/extensions/trend-finder/text-vectors.ts` - Added browser vector creation, hybrid ranking, lexical fallback, timeout, and stale-query handling. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/implementation-notes.md` - Logged browser vector work. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/tasks.md` - Marked browser vector task complete. **BQC Fixes**: * Resource cleanup: Vector timeout clears its timer on success and failure. * State freshness on re-entry: Ranking accepts an `isStale` callback so palette callers can discard results after the query changes. * Failure path completeness: The public ranker returns `lexical-fallback` results instead of leaving callers in a failed or loading-only state. *** ### Task T007 - Create Trend Finder search index builder **Started**: 2026-06-14 11:49 **Completed**: 2026-06-14 11:55 **Duration**: 6 minutes **Notes**: * Added bounded search document projection for topics, sources, evidence, and creator angles from parsed Trend Finder data. * Added scope filtering, async vector ranking, lexical ranking fallback, deterministic hrefs, and topic hash targets. * Added private-string sanitization and vector-array detection helpers for payload safety tests. **Files Changed**: * `src/extensions/trend-finder/search-index.ts` - Added search index projection, scope filtering, ranking, href helpers, and payload-safety guards. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/implementation-notes.md` - Logged search index work. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/tasks.md` - Marked search index task complete. **BQC Fixes**: * Trust boundary enforcement: Search documents sanitize display/search strings before they enter the index. * Contract alignment: Search documents carry display-safe strings, IDs, view IDs, hrefs, and fields only; no vector arrays are stored. *** ### Task T008 - Add similarity-assisted theme fallback grouping **Started**: 2026-06-14 11:55 **Completed**: 2026-06-14 11:59 **Duration**: 4 minutes **Notes**: * Preserved analyst-provided labels as the highest-priority assignment. * Added similarity grouping for unlabeled topics before the existing creator-lens keyword overlap fallback. * Kept fallback output deterministic with fixed thresholds, bounded group size, score/name tie-breakers, and existing fallback provenance. **Files Changed**: * `scripts/extensions/trend-finder/theme-rollups.ts` - Wired feature-hash similarity groups into fallback theme assignment. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/implementation-notes.md` - Logged theme fallback work. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/tasks.md` - Marked theme fallback task complete. **BQC Fixes**: * Contract alignment: Analyst labels remain `ai` provenance; similarity-assisted assignments remain `fallback` provenance. * Failure path completeness: Single-topic or non-tokenizable groups fall through to the existing keyword fallback. *** ### Task T009 - Add similarity fallback topic extraction **Started**: 2026-06-14 11:59 **Completed**: 2026-06-14 12:04 **Duration**: 5 minutes **Notes**: * Added deterministic similarity fallback topic creation for unmatched evidence titles. * Kept fallback clusters bounded, deterministic, and multi-item only so a single unrelated evidence item does not create a topic. * Left AI-mode analyst clustering untouched; this helper only covers deterministic fallback utilities. **Files Changed**: * `scripts/extensions/trend-finder/topics.ts` - Added similarity fallback topic clustering and merged it with keyword-frequency topics. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/implementation-notes.md` - Logged topic fallback work. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/tasks.md` - Marked topic fallback task complete. **BQC Fixes**: * Contract alignment: Fallback topics keep existing `TrendTopic` shape and provenance text while avoiding AI-mode changes. * Failure path completeness: Non-tokenizable, single-item, or already-used evidence falls through without generating extra topics. *** ### Task T010 - Amend ADR 0002 **Started**: 2026-06-14 12:04 **Completed**: 2026-06-14 12:06 **Duration**: 2 minutes **Notes**: * Recorded that Phase 28 Session 11 ships dependency-free feature-hash text vectors. * Kept the local embedding model and vector database path rejected pending a separate future ADR. * Documented that vectors are transient and are not published in browser payloads. **Files Changed**: * `docs/adr/0002-trend-finder-embedding-fallback-clustering.md` - Amended ADR with the feature-hash decision and payload boundary. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/implementation-notes.md` - Logged ADR update. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/tasks.md` - Marked ADR task complete. *** ### Task T011 - Wire collector trace summaries and vector payload guard **Started**: 2026-06-14 12:06 **Completed**: 2026-06-14 12:11 **Duration**: 5 minutes **Notes**: * Added collector trace counts for similarity-assisted fallback theme groups. * Added a deterministic warning path when feature-hash fallback grouping is active without AI output. * Added a final browser-payload guard that rejects vector-shaped numeric arrays before snapshot/write publication. **Files Changed**: * `scripts/extensions/trend-finder/collector.ts` - Added similarity trace summaries and vector-array publication guard. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/implementation-notes.md` - Logged collector wiring work. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/tasks.md` - Marked collector wiring task complete. **BQC Fixes**: * Error information boundaries: Vector guard reports bounded payload paths only. * Failure path completeness: Vector-shaped arrays throw before publication instead of silently shipping browser payload drift. *** ### Task T012 - Add search labels and navigation helpers **Started**: 2026-06-14 12:11 **Completed**: 2026-06-14 12:15 **Duration**: 4 minutes **Notes**: * Added view-model helpers for Trend Finder search-safe topic, source, evidence, and angle labels. * Added a shared Trend Finder search href helper for view and topic hash navigation. * Updated the search index builder to use those helpers instead of local href/label construction. **Files Changed**: * `src/extensions/trend-finder/view-model.ts` - Added search label and navigation helper exports. * `src/extensions/trend-finder/search-index.ts` - Reused view-model label and href helpers. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/implementation-notes.md` - Logged view-model helper work. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/tasks.md` - Marked view-model helper task complete. **BQC Fixes**: * Contract alignment: Palette/index navigation now shares one href helper with the view-model layer. *** ### Task T013 - Create Trend Finder search palette UI **Started**: 2026-06-14 12:15 **Completed**: 2026-06-14 12:25 **Duration**: 10 minutes **Notes**: * Added a Trend Finder command dialog using existing Command/Dialog primitives. * Added scope controls, grouped result rendering, accessible dialog labels, input focus on open, and keyboard result activation. **Files Changed**: * `src/extensions/trend-finder/components/trend-search-palette.tsx` -

Implement palette selection and navigation **Started**: 2026-06-14 12:15 **Completed**: 2026-06-14 12:26 **Duration**: 11 minutes **Notes**: * Added result selection with Enter and item activation. * Added route/hash navigation to the result href, popstate/hashchange dispatch, and topic focus handoff. * Added in-flight navigation state so repeated Enter/click activation cannot trigger duplicate navigation. **Files Changed**: * `src/extensions/trend-finder/components/trend-search-palette.tsx` - Added result selection, default navigation, optional navigation injection for tests, and duplicate-trigger prevention. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/implementation-notes.md` - Logged palette navigation work. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/tasks.md` - Marked palette navigation task complete. **BQC Fixes**: * Duplicate action prevention: Selection is ignored while navigation is in flight. * State freshness on re-entry: Closing/opening resets the in-flight navigation state. *** ### Task T015 - Implement palette fallback and empty states **Started**: 2026-06-14 12:15 **Completed**: 2026-06-14 12:27 **Duration**: 12 minutes **Notes**: * Added loading, empty, error, offline, and lexical-fallback state rows. * Palette searches loaded data only and does not fetch remote data. * Vector ranking failures, missing Web Crypto, stale queries, and timeouts fall back to lexical results through the ranking helper. **Files Changed**: * `src/extensions/trend-finder/components/trend-search-palette.tsx` - Added palette state rendering and async ranking state management. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/implementation-notes.md` - Logged palette state work. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/tasks.md` - Marked palette state task complete. **BQC Fixes**: * Failure path completeness: Ranking errors and vector fallback are caller-visible instead of leaving a spinner. * External dependency resilience: Browser vector ranking has a timeout and pure lexical fallback. *** ### Task T016 - Mount palette and shortcuts in Trend Finder shell **Started**: 2026-06-14 12:27 **Completed**: 2026-06-14 12:31 **Duration**: 4 minutes **Notes**: * Replaced the visibility-only wrapper with a Trend Finder shell wrapper that still provides visibility state. * Mounted the palette for all Trend Finder views. * Added Ctrl/Cmd+K and slash shortcuts with cleanup and input/textarea/contenteditable suppression. **Files Changed**: * `src/extensions/trend-finder/client.tsx` - Mounted the search palette and scoped keyboard listeners in the Trend Finder shell. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/implementation-notes.md` - Logged shell mount work. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/tasks.md` - Marked shell mount task complete. **BQC Fixes**: * Resource cleanup: Global keydown listener is removed when the view wrapper unmounts. * Accessibility and platform compliance: Shortcuts are suppressed for text inputs, textareas, and contenteditable regions. *** ### Task T017 - Add fixture search coverage **Started**: 2026-06-14 12:31 **Completed**: 2026-06-14 12:36 **Duration**: 5 minutes **Notes**: * Added distinctive aliases for topic, hidden/suppressed topic, and research-only topic search assertions. * Added a searchable evidence title for the research-only topic. * Clarified a source label for source-scope search coverage. **Files Changed**: * `src/extensions/trend-finder/fixtures.ts` - Added search-targeted alias, evidence, source, and hidden-topic fixture strings. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/implementation-notes.md` - Logged fixture coverage work. * `.spec_system/specs/phase28-session11-search-palette-and-deterministic-embeddings/tasks.md` -
