Setup (3 tasks) Initial validation context and release-hardening map. * [x] T001 \[S2409] Verify Phase 24 Sessions 01-08 validation status, deferred items, and affected deliverables before adding new closeout coverage (`.spec_system/specs/phase24-session09-end-to-end-validation-release-hardening/implementation-notes.md`) * [x] T002 \[S2409] Audit existing Trend Finder unit, script, component, and browser regression coverage against the Session 09 required fixture list (`scripts/extensions/trend-finder/__tests__/`, `src/extensions/trend-finder/__tests__/`, `tests/e2e/`) * [x] T003 \[S2409] Confirm generated/private artifact ignore coverage, static export output roots, asset cache paths, scheduler logs, and browser-output privacy targets (`.gitignore`, `scripts/check-private-runtime-artifacts.sh`) *** ## Foundation (5 tasks) Focused regression fixtures for Phase 24 feature families. * [x] T004 \[S2409] \[P] Add missing source-local ratio, promoted/pinned exclusion, small-sample cap, and actionability band regressions (`scripts/extensions/trend-finder/__tests__/source-local-signals.test.ts`) * [x] T005 \[S2409] \[P] Add missing enrichment cache hit, stale, saved-count, pruning, estimated spend, actual spend, and cadence projection regressions (`scripts/extensions/trend-finder/__tests__/enrichment-cache.test.ts`, `scripts/extensions/trend-finder/__tests__/spend-accounting.test.ts`) * [x] T006 \[S2409] \[P] Add missing evidence asset blocked, failed, pruned, unsafe-reference, and file-serving privacy regressions (`scripts/extensions/trend-finder/__tests__/evidence-assets.test.ts`, `scripts/lib/__tests__/trend-finder-asset-bridge.test.ts`) * [x] T007 \[S2409] \[P] Add missing source setup target validation, reviewed-source handling, scheduler status, and live progress safe-summary regressions (`scripts/extensions/trend-finder/sources/__tests__/source-setup.test.ts`, `scripts/lib/__tests__/trend-finder-scheduler-status.test.ts`) * [x] T008 \[S2409] \[P] Add missing Workbench local triage, generated Watchlist separation, static export privacy, and local triage exclusion regressions (`src/extensions/trend-finder/components/__tests__/signal-workbench-view.test.tsx`, `scripts/extensions/trend-finder/__tests__/static-brief-export.test.ts`) *** ## Implementation (8 tasks) End-to-end dogfood, private artifact checks, and phase closeout evidence. * [x] T009 \[S2409] Create the release-hardening regression matrix, dogfood plan, command ledger, and expected privacy assertions (`.spec_system/specs/phase24-session09-end-to-end-validation-release-hardening/implementation-notes.md`) * [x] T010 \[S2409] Update complete Phase 24 fixtures for source setup, run progress, Engine Replay, Workbench triage, Brief, static export, spend, assets, and degraded/missing-credential states (`tests/e2e/fixtures/live-data.ts`, `src/extensions/trend-finder/fixtures.ts`) * [x] T011 \[S2409] Create first-run browser dogfood proof from no configured sources through source setup, run-now/live progress, Engine Replay, Workbench, Brief, and static export with explicit loading, empty, error, and offline states (`tests/e2e/trend-finder-release-hardening.spec.ts`) * [x] T012 \[S2409] Expand Engine Replay browser proof for stage progress, spend labels, asset failure labels, source-local evidence labels, and private-string redaction (`tests/e2e/trend-finder-engine-replay.spec.ts`) * [x] T013 \[S2409] Expand static Brief browser proof for safe public links, no private strings, no local triage notes, desktop/mobile overflow, and deterministic generated output (`tests/e2e/trend-finder-static-brief.spec.ts`) * [x] T014 \[S2409] Extend private runtime artifact checks for Phase 24 enrichment cache, asset cache, scheduler state/log, and static Brief export paths using git ignore/status metadata (`scripts/check-private-runtime-artifacts.sh`) * [x] T015 \[S2409] Re-review source compliance for entity identity, promoted/pinned flags, evidence assets, target fields, and spend labels, then record closeout findings (`docs/sources/`, `.spec_system/specs/phase24-session09-end-to-end-validation-release-hardening/security-compliance.md`) * [x] T016 \[S2409] Record folded Outlier source memo completion state, changed files, dogfood observations, residual risks, and any phase PRD closeout note needed for completion (`.spec_system/specs/phase24-session09-end-to-end-validation-release-hardening/implementation-notes.md`, `.spec_system/PRD/phase_24/PRD_phase_24.md`) *** ## Testing (4 tasks) Verification and quality assurance. * [x] T017 \[S2409] Run focused Trend Finder unit, script, component, source setup, scheduler, Workbench, and static export regression suites and record exact results (`package.json`) * [x] T018 \[S2409] Run relevant Playwright Trend Finder specs, including release hardening, Engine Replay, static Brief, and route smoke coverage, and record exact results (`tests/e2e/`) * [x] T019 \[S2409] Run broad release gates: `bun run test`, `bun run typecheck`, `bun run typecheck:scripts`, `bun run lint`, `bun run format:check`, `bun run build`, and `bun run runtime:check-private` (`package.json`) * [x] T020 \[S2409] Validate ASCII encoding, LF endings, `git diff --check`, private artifact invisibility, implementation notes, and security-compliance notes before validate handoff (`.spec_system/specs/phase24-session09-end-to-end-validation-release-hardening/`) *** ## Completion Checklist Before marking session complete: * [x] All tasks marked `[x]` * [x] All tests passing or unrelated blockers documented * [x] All files ASCII-encoded * [x] implementation-notes.md updated * [x] security-compliance.md updated * [x] Ready for the validate workflow step *** ## Next Steps Session complete. Validation and updateprd handoff are recorded in the session artifacts and implementation summary. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase24-session09-end-to-end-validation-release-hardening/tasks.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
