Run final verification **Started**: 2026-06-12 23:03 **Completed**: 2026-06-12 23:20 **Duration**: 17 minutes **Notes**: * Ran focused Trend Finder tests, full Vitest, app typecheck, scripts typecheck, and ASCII validation over changed and untracked files. * Full-suite verification caught an existing visibility-count copy contract that changed when watched counts were added. * Restored the visible-count text as a standalone inline label in Trends and restored the visible-count period in Hidden Gems while keeping watched-count copy additive. **Files Changed**: * `src/extensions/trend-finder/views/trends-view.tsx` - Preserved the existing standalone visible-count text while appending watched-count context. * `src/extensions/trend-finder/views/hidden-gems-view.tsx` - Preserved the existing visible-count sentence shape while appending watched-count context. * `.spec_system/specs/phase27-session03-data-driven-radar-aliases-and-watching-state/tasks.md` -

Logged projection implementation. **BQC Fixes**: * Contract alignment: projection exposes bounded view-model values and explicit fallback states so components do not invent radar positions from missing data. **Verification**: * `bun test ./src/extensions/trend-finder/__tests__/signal-workbench-model.test.ts` - passed. *** ### Task T002 - Inspect Trend Finder surfaces and source-local behavior **Started**: 2026-06-12 21:41 **Completed**: 2026-06-12 21:44 **Duration**: 3 minutes **Notes**: * Read the existing radar panel and confirmed source-name coordinates are decorative and local to `signal-radar.tsx`. * Read Trends and Hidden Gems views and confirmed watching filters can reuse the existing browser-local triage hook with run re-entry keys. * Read Workbench model, controls, table, storage, and triage controls; existing storage uses version 1 with bounded entries and duplicate-write prevention in the hook. * Read source-local docs and script behavior; outlier work can consume existing `sourceLocal` ratios and unavailable states without collector or schema changes. * Read fixtures and tests; fixture data already covers missing saturation and source-local unavailable states, while aliases need more human-facing coverage. **Files Changed**: * `.spec_system/specs/phase27-session03-data-driven-radar-aliases-and-watching-state/tasks.md` - Marked T002 complete and updated progress. * `.spec_system/specs/phase27-session03-data-driven-radar-aliases-and-watching-state/implementation-notes.md` - Logged inspection findings. **BQC Fixes**: * N/A -

Marked T001 complete and updated progress. * `.spec_system/specs/phase27-session03-data-driven-radar-aliases-and-watching-state/implementation-notes.md` - Logged environment and setup verification. **BQC Fixes**: * N/A - setup verification only. *** ## Task Log ### 2026-06-12 - Session Start **Environment verified**: * [x] Prerequisites confirmed * [x] Tools available * [x] Directory structure ready *** --- # Agent Instructions This documentation is published with GitBook.
