# Implementation Summary

**Session ID**: `phase28-session15-documentation-validation-and-release` **Completed**: 2026-06-14 **Duration**: 1.1 hours

***

## Overview

Closed Phase 28 with documentation, validation, security, release, and workflow-state updates. The session aligned Trend Finder manuals and Reference mode tests with shipped Phase 28 behavior only, preserved the retired Trends-Finderz planning material in durable destinations, kept `docs/ongoing-projects/trends-finderz.md` absent, fixed two validation-discovered runtime/test-boundary issues, and marked Phase 28 complete.

## Technical Decisions

1. **Committed Markdown remains the Reference mode authority**: The session kept Reference mode on static manual imports and added phrase tests instead of a dynamic documentation loader.
2. **Deferred source candidates stay non-shipped**: Semantic Scholar, Bluesky, Replicate, X/Twitter, Digg, and similar names remain compliance-first future candidates, not collection approvals.
3. **Validation fixes were accepted inside closeout**: The static Brief marker wording and Apify budget boundary fixes were required to make the release validation truthful rather than merely documented.

***

## Test Results

| Metric   | Value                                |
| -------- | ------------------------------------ |
| Tests    | 3672 Vitest, 94 Playwright           |
| Passed   | 3672 Vitest, 94 Playwright           |
| Coverage | Not generated in this validation run |

Additional gates passed: `bun run typecheck`, `bun run typecheck:scripts`, focused regression tests, scoped Prettier check, ASCII/LF scan, static Brief export, production build, bundle budget, private runtime artifact scan, and `bun audit --json`. Repo-wide `bun run format:check` still reports known older drift outside Session 15 scope.

***

## Lessons Learned

1. Release docs need executable guardrails when manuals are rendered in-product.
2. Static export leak checks can catch marker-shaped fallback copy even when the text is deterministic and local.
3. Sub-second collection-budget edges need to preserve the documented minimum timeout clamp instead of treating positive budget as exhausted.

***

## Future Considerations

Items for future sessions:

1. Run the `audit` workflow next because Phase 28 is fully complete.
2. Keep deferred source candidates on the compliance-first path before any collection-path expansion.
3. Address repo-wide Prettier drift separately from this completed closeout.

# 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_summary.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.
