validation, compliance, cost visibility, run proof, and retro rigor; scoring, runtime, sources, pipeline, and history manuals will restate the current behavior. | | Explicit non-goals | Preserved. | Phase 27 PRD records no `tbts`/peak estimates, no X/Twitter source, no hotlinked thumbnails, no landing-page media, and no single-creator hardcoding; closeout docs will keep these boundaries current. | ### Deletion Precondition `docs/ongoing-projects/alpha-radar.md` can be deleted after T010-T019 because: * The complete improvement map is preserved in `.spec_system/PRD/phase_27/PRD_phase_27.md`. * Shipped behavior is documented in committed Trend Finder manuals rendered by Reference mode. * Deferred source candidates and explicit non-goals are retained in current docs/PRD artifacts. * Do-not-regress areas are retained in the PRD and reinforced in security/compliance and considerations. * The old file contains planning language and Unicode text that should not remain the current source of truth after closeout. *** ## Validation Commands Confirmed commands from `package.json`: | Purpose | Command | | --------------------------------- |

a dedicated housekeeping session if the project wants repo-wide `bun run format:check` to be green. *** ## Documentation Audit Findings ### Scoring Manual * Missing explicit Phase 27 derived metric inventory: saturation, hidden-gem score, consensus ratio, role shares, builder signal, and risk flags. * Hidden Gems sort language is stale: implementation now ranks by continuous hidden-gem score before score/novelty tie-breakers. * Momentum section omits velocity acceleration, significance, burst support, and unavailable states. * Source-local lift caps are present, but cross-source outlier preset and outlier ideas need clearer relationship to scoring. * No-invented-metrics boundary should explicitly say `tbts`, peak-day estimates, and RRF are not shipped scoring inputs. ### History Manual * Missing private daily topic series and bounded 14-day sparkline behavior. * Missing Hugging Face model download observation deltas and explicit no-baseline/unavailable states. * Prediction writer section is stale: dated target windows, target lifecycle, and target-date grading are now part of the record. * Retro section omits calibration metrics: hit rate, Brier score, resolved counts, and stale pending handling in the summary. * Missing Story Log projection details and verdict/due-state filtering boundaries. ### UI Surfaces Manual * Trends/Hidden Gems/Watchlist section does not mention continuous gem-score sorting, watching filters, lifecycle chips, aliases, or risk chips. * Signal Radar section is stale: radar now uses data-driven axes instead of purely decorative source-name positions. * Brief section omits movement groups, today's pick, demand centers, theme rollups, calibration, Story Log, and angle-pack copy. * Workbench section omits lifecycle, saturation, gem score, builder signal, risk flag, sparkline, theme grouping, cross-source outlier preset, outlier idea, competitor, and watching controls. * Static Brief section omits Phase 27 projections for movement groups, today's pick, demand centers, Story Log, angle packs, and bounded sparklines. ### Cross-Manual Set * Creator Lens manual omits bounded competitor names, validation warnings, bridge/cache parsing, collect-time public channel-title matching, and angle-pack influence. * Pipeline manual omits Phase 27 stages after scoring: velocity dynamics, lifecycle, convergence, demand clusters, theme rollups, outlier ideas, and browser-safe Story Log projection. * Runtime/provenance manual omits analyst fields added in Phase 27: target lifecycle/date, demand brief, theme labels, outlier ideas, contrarian angle, plain explainer, and suggested title. * Sources manual needs a durable deferred-source-candidates section and Hugging Face download delta behavior. * Concepts manual needs core objects for lifecycle, convergence, demand cluster, theme, watching state, angle pack, and outlier idea. * Extension README current-behavior list and certification commands need Phase 27 closeout updates. ### Reference Mode Registry * All eight registered Trend Finder manual source paths exist. * Import set is complete for the current manuals; no new manual file is required. * Registry descriptions are stale for scoring, creator lens, history, UI surfaces, runtime, and sources; update descriptions after manual edits. *** ## Task Log ### 2026-06-13 - Session Start

registry metadata updates. * Initial focused test failed because the scoring registry description dropped the stable `actionability` keyword expected by `reference-docs.test.ts`. * Restored stable metadata anchors while keeping Phase 27 descriptions current. * Re-ran focused tests successfully. * Ran ASCII validation across changed Markdown/spec files successfully. * Ran phrase checks for closeout terms: no-invented-metrics, Story Log, Demand Centers, deferred source candidates, Semantic Scholar, browser-local watching, cross-source outlier, target-date, angle-pack, and Hugging Face download. **Commands**: * `bun run test -- src/extensions/trend-finder/__tests__/reference-docs.test.ts src/extensions/trend-finder/components/__tests__/trend-reference-doc-viewer.test.tsx src/routes/__tests__/extensions-routes.test.tsx` - PASS, 3 files / 23 tests. * `perl -ne '...' ` - PASS, no non-ASCII bytes found. * `rg -n "" docs/extensions .spec_system/specs/phase27-session12-documentation-validation-and-release/implementation-notes.md` - PASS, expected phrases present. **Files Changed**: * `src/extensions/trend-finder/reference-docs.ts` - restored stable description keywords after focused test failure. * `.spec_system/specs/phase27-session12-documentation-validation-and-release/tasks.md` - marked T020 complete. * `.spec_system/specs/phase27-session12-documentation-validation-and-release/implementation-notes.md` - logged T020. **BQC Fixes**: * Contract alignment: restored registry description keywords expected by the Reference docs test. *** ### Task T021 - Run typechecks, full tests, and format check **Started**: 2026-06-13 07:37 **Completed**: 2026-06-13 07:43 **Duration**: 6 minutes **Notes**: * App typecheck passed. * Script typecheck passed. * Full Vitest suite passed. * Initial repo-wide format check failed on 56 files, including session-owned files and pre-existing files. * Ran Prettier write only on files touched in this session. * Scoped Prettier check for session-owned files passed. * Repo-wide format check still fails on 45 pre-existing files outside this session: older Phase 27 Session 01-04/08-11 spec artifacts, `.spec_system/PRD/PRD.md`, `docs/ongoing-projects/trends-finderz.md`, `scripts/extensions/trend-finder/demand-clusters.ts`, and `scripts/extensions/trend-finder/static-brief-export.ts`. **Commands**: * `bun run typecheck` - PASS. * `bun run typecheck:scripts` - PASS. * `bun run test` - PASS, 282 files / 3470 tests. * `bun run format:check` - FAIL due formatting drift. * `bunx prettier --write ` - PASS. * `bunx prettier --check ` - PASS. * `bun run format:check` - FAIL due 45 pre-existing files outside session scope. **Files Changed**: * Session-owned docs and spec artifacts - formatted with Prettier. * `.spec_system/specs/phase27-session12-documentation-validation-and-release/tasks.md` - marked T021 complete. * `.spec_system/specs/phase27-session12-documentation-validation-and-release/implementation-notes.md` - logged T021. **BQC Fixes**: * N/A - validation/documentation task. *** ### Task T022 - Run static Brief, private-artifact, and payload budget checks **Started**: 2026-06-13 07:44 **Completed**: 2026-06-13 07:50 **Duration**: 6 minutes **Notes**: * Private runtime artifact check passed. * Bundle budget check passed with 0 violations. * Extension payload-size verification passed for the local Trend Finder runtime item. * The default static Brief dry-run correctly failed because the local `src/data/live-data.json` Trend Finder item has empty data and a prior validation-error state. * Re-ran the static Brief dry-run against the committed generated-safe payload at `src/data/live-data.example.json`; it passed without writing final output and without mutating local runtime state. **Commands**: * `bun run trend-finder:export-brief -- --dry-run --json` - FAIL, expected local data precondition failure: `missing_trend_finder_data`. * `bun run trend-finder:export-brief -- --input src/data/live-data.example.json --dry-run --json` - PASS, status `dry-run`, topics 2, evidence 2, sources 2, copied assets 0, unsafe asset fallbacks 0, warnings 0. * `bun run runtime:check-private` - PASS. * `bun run budget:check` - PASS, 0 violations, total client JS gzip 1121 KB / 1200 KB. * `bun -e ''` - PASS, 1157 bytes / 1048576 byte limit. **Files Changed**: * `.spec_system/specs/phase27-session12-documentation-validation-and-release/tasks.md` - marked T022 complete. * `.spec_system/specs/phase27-session12-documentation-validation-and-release/implementation-notes.md` - logged T022. **BQC Fixes**: * N/A - validation/documentation task. *** ### Task T023 - Run e2e validation **Started**: 2026-06-13 07:50 **Completed**: 2026-06-13 08:05 **Duration**: 15 minutes **Notes**: * Ran the full Playwright suite. * Initial full-suite run failed 2 Trend Finder e2e assertions after 92 passed tests. * Root cause was stale e2e expectations against the current Phase 27 fixture/UI: Engine Replay source-local counters now render `Ready 5`, `Unavailable 3`, `Excluded 1`, and the Brief view renders the Phase 27 sections (`Today's pick`, `Demand Centers`, `Prediction and retro`) instead of the old `Headline finding` label. * Updated the e2e assertions only; no runtime application code was changed. * Focused Trend Finder e2e specs passed after the assertion update. * Final full e2e suite passed. **Commands**: * `bun run test:e2e` - FAIL, 92 passed / 2 failed stale Trend Finder assertions. * `bunx playwright test tests/e2e/trend-finder-engine-replay.spec.ts tests/e2e/trend-finder.spec.ts` - FAIL, 12 passed / 1 failed stale unavailable-counter assertion. * `bunx playwright test tests/e2e/trend-finder-engine-replay.spec.ts tests/e2e/trend-finder.spec.ts` - PASS, 13 passed. * `bun run test:e2e` - PASS, 94 passed in 5.7 minutes. **Files Changed**: * `tests/e2e/trend-finder-engine-replay.spec.ts` - aligned source-local counter expectations with the current Engine Replay model. * `tests/e2e/trend-finder.spec.ts` - aligned Brief navigation assertions with the current Phase 27 Brief sections. * `.spec_system/specs/phase27-session12-documentation-validation-and-release/tasks.md` - marked T023 complete. * `.spec_system/specs/phase27-session12-documentation-validation-and-release/implementation-notes.md` - logged T023. **BQC Fixes**: * Test contract alignment: corrected stale e2e expectations to match the current Phase 27 fixtures and rendered UI. *** ### Task T024 - Complete validation report and handoff **Started**: 2026-06-13 08:05 **Completed**: 2026-06-13 08:10 **Duration**: 5 minutes **Notes**: * Created the session validation report with task completion, command results, coverage proof, security result, and residual non-blocking drift. * Marked the session task checklist complete and updated the next step to the validate workflow. * Recorded the final release readiness result as PASS with known pre-existing repo-wide format drift. **Commands**: * `bunx prettier --write ` - PASS; new validation report formatted. * `bunx prettier --check ` - PASS. * `perl -ne '' ` - PASS. * `git diff --check` - PASS. **Files Changed**: * `.spec_system/specs/phase27-session12-documentation-validation-and-release/validation.md` - created validation report. * `.spec_system/specs/phase27-session12-documentation-validation-and-release/tasks.md` - marked T024 and completion checklist complete. * `.spec_system/specs/phase27-session12-documentation-validation-and-release/implementation-notes.md` - logged T024. **BQC Fixes**: * N/A - validation/documentation handoff task. *** --- # Agent
