### Task T022 - Run static Brief, payload, private-artifact, and audit checks

**Started**: 2026-06-21 07:44 **Completed**: 2026-06-21 07:58 **Duration**: 14 minutes

**Notes**:

* `bun run trend-finder:export-brief -- --dry-run --json` passed with `qaStatus: "pass"`, 0 QA issues, 0 warnings, 9 topics, 203 evidence rows, 12 sources, and 29 assets.

### Task T021 - Run typecheck, full Vitest, and scoped formatting

**Started**: 2026-06-21 07:33 **Completed**: 2026-06-21 07:44 **Duration**: 11 minutes

**Notes**:

* Initial `bun run typecheck` failed because the first audit remediation set the Vite override to 7.3.5, which downgraded the direct Vite type surface and rejected `vite.config.ts` `tsconfigPaths`.
* Updated the Vite override to 8.0.16, reran `bun install`, and `bun run typecheck` passed.
* `bun run typecheck:scripts` passed.
* `bun run test` passed: 327 test files, 3856 tests.
* Initial scoped Prettier check reported 8 touched files needing formatting. Ran scoped Prettier write and the scoped check then passed.
* No unrelated repo-wide formatting drift was measured in this task because the required proof was scoped to touched files.

**Files Changed**:

* `package.json` - Corrected Vite override to 8.0.16 after typecheck failure.
* `bun.lock` - Regenerated by `bun install`.
* Touched Markdown/spec/test files - Formatted with scoped Prettier.
* `.spec_system/specs/phase29-session18-documentation-validation-and-release/validation.md` - Recorded T021 command evidence.
* `.spec_system/specs/phase29-session18-documentation-validation-and-release/tasks.md` - Marked T021 complete and updated progress summary.
* `.spec_system/specs/phase29-session18-documentation-validation-and-release/implementation-notes.md` - Logged the task result.

**BQC Fixes**:

* Contract alignment: Corrected dependency override after it changed the direct Vite type contract.
* Failure path completeness: Recorded the initial failure and the applied fix instead of hiding the transient validation failure.

***

### Task T020 - Run Reference docs and Markdown safety checks

**Started**: 2026-06-21 07:24 **Completed**: 2026-06-21 07:33 **Duration**: 9 minutes

**Notes**:

* Initial Reference docs test run failed because an older Phase 24 assertion allowed `Instagram` only in the sources manual.
* Updated the assertion to also allow UI surfaces to mention Instagram when documenting the Phase 29 social-reach non-goal.
* Final `bun run test -- src/extensions/trend-finder/__tests__/reference-docs.test.ts` passed: 1 file, 10 tests.
* Planned-feature wording grep found no podcast/social shipped-source drift.
* ASCII and CRLF checks passed for changed docs/spec/test files.

**Files Changed**:

* `src/extensions/trend-finder/__tests__/reference-docs.test.ts` - Adjusted Phase 24 source-copy assertion for Phase 29 UI non-goal wording.
* `.spec_system/specs/phase29-session18-documentation-validation-and-release/validation.md` - Recorded T020 validation evidence.
* `.spec_system/specs/phase29-session18-documentation-validation-and-release/tasks.md` - Marked T020 complete and updated progress summary.
* `.spec_system/specs/phase29-session18-documentation-validation-and-release/implementation-notes.md` - Logged the task result.

**BQC Fixes**:

* Contract alignment: Fixed Reference test expectations so deferred social-source wording is allowed only where the docs intentionally record the non-goal.

***

### Task T019 - Update cumulative considerations

**Started**: 2026-06-21 07:20 **Completed**: 2026-06-21 07:24 **Duration**: 4 minutes

**Notes**:

### Task T018 - Update cumulative security/compliance

**Started**: 2026-06-21 07:11 **Completed**: 2026-06-21 07:20 **Duration**: 9 minutes

**Notes**:

* Ran `bun audit --json`; initial result found vulnerabilities in transitive or pinned packages.
* Applied scoped dependency remediation with direct `js-yaml` upgrade and package overrides for vulnerable transitive packages.
* Ran `bun install` and re-ran `bun audit --json`; final result returned `{}` with exit 0.
* Updated cumulative security/GDPR posture for Phase 29 no-new-surface review, source-boundary posture, dependency audit result, and clean-state evidence.

**Files Changed**:

* `package.json` - Added audit overrides and updated `js-yaml` to `^5.0.0`.
* `bun.lock` - Regenerated by `bun install`.
* `.spec_system/SECURITY-COMPLIANCE.md` - Added Phase 29 security/GDPR/dependency posture.
* `.spec_system/specs/phase29-session18-documentation-validation-and-release/tasks.md` - Marked T018 complete and updated progress summary.
* `.spec_system/specs/phase29-session18-documentation-validation-and-release/implementation-notes.md` - Logged the task result.

**BQC Fixes**:

* External dependency resilience: Resolved audit findings instead of documenting a failing dependency posture.

***

# 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/phase29-session18-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.
