### Task T001 - Verify Session 15 prerequisites and retired planning file status

**Started**: 2026-06-14 16:10 **Completed**: 2026-06-14 16:11 **Duration**: 1 minute

**Notes**:

* Ran `.spec_system/scripts/analyze-project.sh --json`; current session resolved to `phase28-session15-documentation-validation-and-release`.
* Confirmed Phase 28 Sessions 01-14 are listed as completed in spec-system state and that the Session 15 spec directory exists.
* Confirmed this session is closeout-only: documentation, Reference mode checks, validation, security, PRD, and release records only.
* Confirmed `docs/ongoing-projects/trends-finderz.md` is absent at implementation start and must not be recreated.
* Ran `.spec_system/scripts/check-prereqs.sh --json --env`; environment checks passed.
* Tool prereq check reported missing global `tsc`, `vitest`, `prettier`, and `eslint`, but the repo has the required local binaries under `node_modules/.bin`.

**Files Changed**:

* `.spec_system/specs/phase28-session15-documentation-validation-and-release/implementation-notes.md` - created the session implementation log and recorded prerequisite verification.

**BQC Fixes**:

* N/A - verification and documentation-only task.

***

### Task T002 - Create closeout artifact scaffolds

**Started**: 2026-06-14 16:11 **Completed**: 2026-06-14 16:12 **Duration**: 1 minute

**Notes**:

* Created the session coverage matrix artifact with source-status, matrix, and final-decision sections.
* Created the session security closeout artifact with credential, bridge, hosted storage, payload privacy, source compliance, GDPR, and audit sections.
* Created the session validation report artifact with the required command inventory and release decision section.
* Kept all scaffolds as explicit in-progress records to avoid claiming validation or coverage before execution.

**Files Changed**:

* `.spec_system/specs/phase28-session15-documentation-validation-and-release/coverage.md` - added closeout coverage scaffold.
* `.spec_system/specs/phase28-session15-documentation-validation-and-release/security-compliance.md` - added security and compliance closeout scaffold.
* `.spec_system/specs/phase28-session15-documentation-validation-and-release/validation.md` - added validation report scaffold.
* `.spec_system/specs/phase28-session15-documentation-validation-and-release/implementation-notes.md` - updated progress and task log.

**BQC Fixes**:

* N/A - artifact scaffolding only.

***

### Task T003 - Confirm validation command set and drift expectations

**Started**: 2026-06-14 16:12 **Completed**: 2026-06-14 16:12 **Duration**: 1 minute

**Notes**:

* Confirmed required project scripts in `package.json`: `typecheck`, `typecheck:scripts`, `test`, `format:check`, `test:e2e`, `trend-finder:export-brief`, `budget:check`, and `runtime:check-private`.
* Confirmed dependency audit command is `bun audit`.
* Confirmed Playwright coverage exists for Trend Finder main surfaces, Engine Replay Reference/replay route, static Brief export, and release hardening under `tests/e2e/`.
* Confirmed `scripts/check-private-runtime-artifacts.sh` checks generated private Trend Finder, scheduler, logs, coverage, and Playwright report paths through git ignore/tracking metadata without reading private contents.
* Confirmed `scripts/check-bundle-budget.sh` requires a prior production build and checks JS gzip, CSS raw size, and total JS gzip budgets.
* Confirmed `.spec_system/CONSIDERATIONS.md` already records known repo-wide formatting drift; later validation must separate release blockers from unrelated drift and provide scoped formatting proof for changed files if needed.

**Validation Command Inventory**:

* `bun run typecheck`
* `bun run typecheck:scripts`
* `bun run test`
* `bun run format:check`
* `bun run test:e2e`
* `bun run trend-finder:export-brief`
* `bun run build`
* `bun run budget:check`
* `bun run runtime:check-private`
* `bun audit`
* `bunx prettier --check <changed files>` for scoped formatting proof when repo-wide drift is unrelated.

**Files Changed**:

* `.spec_system/specs/phase28-session15-documentation-validation-and-release/implementation-notes.md` - recorded validation command inventory and known drift expectations.

**BQC Fixes**:

* N/A - validation inventory only.

***

### Task T004 - Build heading-by-heading coverage matrix

**Started**: 2026-06-14 16:12 **Completed**: 2026-06-14 16:13 **Duration**: 1 minute

**Notes**:

* Mapped the retired Trends-Finderz planning source material to the Phase 28 PRD, session PRD stubs, session specs, manuals, ADR 0002, and this closeout artifact.
* Covered source anchors, method and caveats, numbered items 1.1-10.4, already-ahead areas, explicit non-goals, deferred candidates, tier sequencing, and deletion status.
* Recorded that `docs/ongoing-projects/trends-finderz.md` was absent at implementation start and should remain absent after final release validation.
* Avoided recreating stale planning content; the artifact records durable destinations and decisions only.

**Files Changed**:

* `.spec_system/specs/phase28-session15-documentation-validation-and-release/coverage.md` - replaced scaffold with complete coverage matrix and deletion decision.
* `.spec_system/specs/phase28-session15-documentation-validation-and-release/implementation-notes.md` - updated progress and task log.

**BQC Fixes**:

* N/A - coverage documentation only.

**Notes**:

* Reviewed `docs/extensions/trend-finder-scoring.md` against Phase 28 Sessions 01-14.
* Existing coverage is strong for confidence dampener, lifecycle multiplier, topic noise downrank, signal aging, saturation, risk flags, action verdicts, hidden gems, and generated watchlist rules.
* Gaps to update in T010: make deduplicated scoring evidence explicit, document scoring calibration version closeout behavior, clarify unavailable-state and no-invented-metrics boundaries near the top, and distinguish generated Watchlist rules from browser-local pin baselines.

**Files Changed**:

* `.spec_system/specs/phase28-session15-documentation-validation-and-release/implementation-notes.md` - recorded scoring audit findings.

**BQC Fixes**:

* N/A - documentation audit only.

**Started**: 2026-06-14 16:15 **Completed**: 2026-06-14 16:15 **Duration**: 1 minute

**Notes**:

* Reviewed `docs/extensions/trend-finder-pipeline.md` for collection health, retention, static Brief QA, payload limits, source-state transitions, and export privacy.
* Existing coverage includes the aggregate path, static Brief export, private cache retention, private artifact boundaries, source spend accounting, and evidence asset handling.
* Gaps to update in T011: add an explicit closeout section tying dedup counters, source coverage counters, payload validation, static Brief QA, private-artifact scan, and source-state transitions into the Phase 28 release gate.

**Files Changed**:

* `.spec_system/specs/phase28-session15-documentation-validation-and-release/implementation-notes.md` - recorded pipeline audit findings.

* Reviewed `docs/extensions/trend-finder-ui-surfaces.md` for visibility bands, suppressed-noise summary, Action Queue, pins, notes, tags, search palette, KPI strip, Markdown export, and Reference mode.
* Existing coverage includes the tab model, KPI strip, search palette, Workbench, visibility controls, Brief, static Brief export, and Reference mode.
* Gaps to update in T012: name the Action Queue/Decisions mapping explicitly, add browser-local pin baseline, note, and tag behavior to the Watchlist section, and make visibility-band/suppressed-noise behavior easier to find from the top-level surfaces section.

**Files Changed**:

* `.spec_system/specs/phase28-session15-documentation-validation-and-release/implementation-notes.md` - recorded UI surfaces audit findings.

**BQC Fixes**:

* N/A - documentation audit only.

***

### Task T008 - Audit source manual gaps

**Started**: 2026-06-14 16:16 **Completed**: 2026-06-14 16:16 **Duration**: 1 minute

**Notes**:

* Reviewed `docs/extensions/trend-finder-sources.md` for keyword packs, scan modes, rotation, coverage QA, direct adapters, fallback behavior, spend labels, and deferred candidates.
* Existing coverage includes the implemented direct adapter table, reviewed Apify declaration table, keyword scan modes, coverage QA, env keys, source health, Source Setup, spend/cache labels, and deferred source coverage candidates.
* Gaps to update in T013: explicitly connect deferred candidates to the Trends-Finderz closeout as compliance-first future work, call out zero-cost public API spend labels for skipped Apify fallbacks in the closeout context, and sharpen direct readiness/fallback wording for release reviewers.

**Files Changed**:

* `.spec_system/specs/phase28-session15-documentation-validation-and-release/implementation-notes.md` - recorded source manual audit findings.

**BQC Fixes**:

* N/A - documentation audit only.

**Notes**:

* Reviewed `src/extensions/trend-finder/reference-docs.ts` and `src/extensions/trend-finder/__tests__/reference-docs.test.ts`.
* Registry order, imports, labels, titles, source paths, and static Markdown import model are stable and should not need structural changes.
* Existing tests verify stable metadata, non-empty Markdown, registered Markdown link resolution, internal Trend Finder link resolution, Phase 24 boundary phrases, and absence of example-specific source copy.
* Gaps to update in T016: add Phase 28 required boundary phrases for scoring, pipeline, sources, runtime, and UI manuals; add planned-feature drift assertions so docs do not imply deferred candidates are shipped.

**Files Changed**:

* `.spec_system/specs/phase28-session15-documentation-validation-and-release/implementation-notes.md` - recorded Reference mode audit findings.

**BQC Fixes**:

* N/A - registry/test audit only.

* `bun run typecheck:scripts` - PASS after fallback-copy fix.
* `VITE_CLAUDE_OS_ENABLED_EXTENSIONS=trend-finder bun run scripts/scheduler-runner.ts --job trend-finder` - PASS, scoped payload regenerated.
* `bun run trend-finder:export-brief` - PASS, 6 topics, 104 evidence rows, 11 sources, 0 warnings.
* `bun run build` - PASS.
* `bun run budget:check` - PASS, 0 violations, total client JS gzip 1194 KB / 1200 KB.
* `bun run runtime:check-private` - PASS.
* `bun audit --json` - PASS, returned `{}`.

**BQC Fixes**:

* Error information boundaries: fixed generated fallback copy that matched a raw-runtime marker pattern before static export promotion.

**Started**: 2026-06-14 16:49 **Completed**: 2026-06-14 17:05 **Duration**: 16 minutes

**Notes**:

* Completed the session security report with a PASS decision for no new credential flow, dependency, source adapter, public transfer path, hosted storage path, runtime bridge, admin write surface, local write surface, or personal-data class.
* Completed the validation report with a PASS implement-handoff decision and the known repo-wide Prettier drift exception.
* Final consistency rerun found a flaky Apify one-second budget boundary in the full Vitest suite. Fixed the guard so only zero or negative remaining budget is treated as exhausted, while preserving the one-second minimum timeout clamp.
* Reran focused Apify, demand-cluster, and static Brief tests successfully.
* Reran script typecheck and the full Vitest suite successfully after the Apify boundary fix.
* Updated the task checklist to 25/25 and recorded the session as ready for the validate workflow step.

**Files Changed**:

* `.spec_system/specs/phase28-session15-documentation-validation-and-release/security-compliance.md` - completed session security/GDPR closeout and final decision.
* `.spec_system/specs/phase28-session15-documentation-validation-and-release/validation.md` - completed validation report, release decision, static export note, and Apify budget boundary note.
* `.spec_system/specs/phase28-session15-documentation-validation-and-release/tasks.md` - marked T025 and completion checklist complete.
* `.spec_system/specs/phase28-session15-documentation-validation-and-release/implementation-notes.md` - recorded final progress and release-ready handoff.
* `scripts/extensions/trend-finder/sources/apify-adapter.ts` - fixed the positive sub-second collection-budget boundary.

**Verification**:

* `bun run test -- scripts/extensions/trend-finder/__tests__/apify-adapter.test.ts scripts/extensions/trend-finder/__tests__/demand-clusters.test.ts scripts/extensions/trend-finder/__tests__/static-brief-export.test.ts` - PASS, 3 files and 15 tests.
* `bun run typecheck:scripts` - PASS after Apify boundary fix.
* `bun run test` - PASS, 307 files and 3672 tests.
* `bunx prettier --check <Session 15 touched files>` - PASS after final report updates.
* `rg -nP '[^\\x00-\\x7F]' <Session 15 touched files>` - PASS, no matches.
* `test -e docs/ongoing-projects/trends-finderz.md` - PASS absent-file check; retired file remains absent.

**BQC Fixes**:

* External dependency resilience: Apify collection-budget handling now preserves the documented one-second timeout clamp for any positive remaining budget instead of skipping the first source because of setup overhead.

# 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/phase28-session15-documentation-validation-and-release/implementation-notes.md?ask=<question>&goal=<endgoal>
```

`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.
