### Commands

* `bun run lint` - PASS.
* `bun run typecheck` - PASS.
* `bun run typecheck:scripts` - PASS.
* `bun run scripts/extensions/trend-finder/measure-payload-size.ts src/data/live-data.example.json --json` - PASS, Trend Finder browser data payload 14138 bytes against the 1048576 byte extension boundary.

### Failed Tests

None.

## 5. Database/Schema Alignment

### Status: N/A

*N/A because the session introduced no database tables, migrations, indexes, constraints, ORM metadata, persisted hosted storage, or seed data changes.*

### Issues Found

N/A -- no DB-layer changes.

***

## 6. Success Criteria

From spec.md:

### Functional Requirements

* [x] High-quality unclustered fixture evidence produces private seed-candidate rows with evidence IDs and collision checks.
* [x] Repeated weak identity or new canonical ID fixtures produce reviewable candidates without mutating canonical seeds.
* [x] Source-local outlier fixtures with weak topic identity produce bounded review rows.
* [x] Rows that exactly collide with reviewed canonical aliases or keywords are marked as collisions or suppressed according to the helper contract.
* [x] Every row includes `manual_review_required: true`.
* [x] The collector does not start new collection, add new sources, edit keyword packs, or write canonical topic seed files.
* [x] Browser payloads and static Brief output expose no seed-candidate row contents, proposed aliases, private paths, raw diagnostics, prompts, provider responses, tokens, or credential-shaped strings.

### Testing Requirements

* [x] Unit tests written and passing for candidate derivation, collision checks, row bounds, deterministic ordering, no-signal behavior, and privacy-safe serialization.
* [x] Private diagnostics tests prove the artifact is written privately and only safe manifest metadata reaches browser payloads.
* [x] Collector tests prove no automatic collection or keyword/canonical mutation occurs.
* [x] Identity and normalization tests prove existing behavior is unchanged while required context remains available.
* [x] Payload-size and private-artifact checks remain green.

### Quality Gates

* [x] All files ASCII-encoded.
* [x] Unix LF line endings.
* [x] Code follows project conventions.
* [x] New schema branches use explicit fallback/default behavior.

## 7. Conventions Compliance

### Status: PASS

| Category       | Status | Notes                                                                                            |
| -------------- | ------ | ------------------------------------------------------------------------------------------------ |
| Naming         | PASS   | Names are descriptive and preserve Trend Finder boundary language.                               |
| File Structure | PASS   | Script helpers and tests are in existing Trend Finder and AI runtime locations.                  |
| Error Handling | PASS   | Candidate generation and private diagnostics write failures degrade to warnings/error artifacts. |
| Comments       | PASS   | No obvious noisy or commented-out code introduced.                                               |
| Testing        | PASS   | Focused tests live near the covered script behavior.                                             |

### Convention Violations

None.

## 8. Security & GDPR Compliance

**Full report**: See `security-compliance.md` in this session directory.

#### Summary

| Area     | Status | Findings |
| -------- | ------ | -------- |
| Security | PASS   | 0 issues |
| GDPR     | N/A    | 0 issues |

### Critical Violations

None.

## 9. Behavioral Quality Spot-Check

### Status: PASS

*Checklist active because this session produced application/script code.*

**Checklist applied**: Yes **Files spot-checked**:

* `scripts/extensions/trend-finder/seed-candidates.ts`
* `scripts/extensions/trend-finder/private-diagnostics.ts`
* `scripts/extensions/trend-finder/collector.ts`
* `scripts/extensions/trend-finder/topics.ts`
* `src/extensions/trend-finder/schema.ts`

| ------------------ | ------ | -------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------- |
| Trust boundaries   | PASS   | `scripts/extensions/trend-finder/seed-candidates.ts`     | Zod input schemas, bounded arrays, reviewed evidence filtering, and proposal normalization constrain private candidate rows. |
| Resource cleanup   | PASS   | `scripts/extensions/trend-finder/private-diagnostics.ts` | Atomic temp-file writes clean up temp paths on failure and use restricted file modes.                                        |
| Mutation safety    | PASS   | `scripts/extensions/trend-finder/collector.ts`           | Candidate generation is read-only and feeds private diagnostics only; tests cover no canonical seed or keyword mutation.     |
| Failure paths      | PASS   | `scripts/extensions/trend-finder/collector.ts`           | Generation and diagnostics failures produce safe warning/error paths without row/path leakage.                               |
| Contract alignment | PASS   | `src/extensions/trend-finder/schema.ts`                  | Manifest artifact IDs/kinds are defaulted and legacy parsing remains covered by tests.                                       |

### Violations Found

None.

### Fixes Applied During Validation

None.

## Validation Result

### PASS

The session is complete. All tasks are marked complete, all deliverables exist, files are ASCII/LF, tests and local quality checks pass, private seed-candidate rows stay out of browser payloads, and no security, GDPR, database, or behavioral quality blockers were found.

### Required Actions

None.

## Next Steps

Run updateprd to mark session complete.

# 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-session10-seed-candidate-review-artifact/validation.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.
