### Failed Tests

## 5. Database/Schema Alignment

### Status: N/A

N/A - no DB-layer changes.

* [x] Matching schema artifact exists for each relevant DB-layer change
* [x] Code and schema artifacts are aligned
* [x] Migration/status/diff check passed locally
* [x] Seed or rollback updates included when conventions require them

### Issues Found

N/A - no DB-layer changes

***

## 6. Success Criteria

From spec.md:

### Functional Requirements

* [x] Saved Creator Lens competitor lists affect the next collector run only; browser drafts remain local until saved.
* [x] Lens bridge rejects oversized lists, malformed names, unknown fields, and missing or invalid tokens.
* [x] Competitor flags appear only on evidence whose public YouTube channel-title entity matches a configured competitor name.
* [x] Analyst output validates `contrarianAngle`, `plainExplainer`, and `suggestedTitle`; invalid or missing output falls back deterministically with warnings.
* [x] Legacy payloads and saved lens configs without new fields keep parsing.

### Testing Requirements

* [x] Focused unit tests cover lens storage, saved config, bridge validation, competitor matching, analyst validation, collector fallback, view models, and static Brief projection.
* [x] Component tests cover Creator Lens editor, card/Brief angle blocks, evidence chips, and Workbench evidence rows.
* [x] Manual-flow validation is covered by DOM interaction tests for draft edit, save, save-and-run ordering, and copy-ready output on Trends and Brief.

### Non-Functional Requirements

* [x] Browser-visible payload remains bounded under the shared 1 MB extension payload limit through schema maxes, list caps, and projection limits.
* [x] No raw prompts, provider responses, local paths, tokens, Actor inputs, or raw source payloads enter browser state or static export.
* [x] YouTube compliance boundary remains public metadata only.

### Quality Gates

* [x] All files ASCII-encoded.
* [x] Unix LF line endings.
* [x] Code follows project conventions.
* [x] `bun run typecheck:scripts` passes.
* [x] Focused Vitest suites for changed files pass.

## 7. Conventions Compliance

### Status: PASS

| Category       | Status | Notes                                                                                                          |
| -------------- | ------ | -------------------------------------------------------------------------------------------------------------- |
| Naming         | PASS   | New names match Trend Finder terminology; no new global `findtrend` identifiers added.                         |
| File Structure | PASS   | Script utilities, script tests, browser components, hooks, and view-model tests are in existing local folders. |
| Error Handling | PASS   | Bridge and collector failure paths are explicit; matching failure degrades with warnings.                      |
| Comments       | PASS   | No commented-out code or noisy comments found in reviewed changes.                                             |
| Testing        | PASS   | Focused tests stay close to behavior and cover script, schema, view-model, and component paths.                |

### Convention Violations

None

## 8. Security & GDPR Compliance

### Status: PASS

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

#### Summary

| Area     | Status | Findings |
| -------- | ------ | -------- |

## 9. Behavioral Quality Spot-Check

### Status: PASS

**Checklist applied**: Yes **Files spot-checked**: `src/extensions/trend-finder/creator-lens-competitors.ts`, `src/extensions/trend-finder/hooks/use-creator-lens-draft.ts`, `scripts/lib/trend-finder-lens-bridge.ts`, `scripts/extensions/trend-finder/collector.ts`, `scripts/lib/ai-runtime/trend-analyst.ts`, `scripts/extensions/trend-finder/static-brief-renderer.ts`

| ------------------ | ------ | ------------------------------------------------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------- |
| Trust boundaries   | PASS   | `scripts/lib/trend-finder-lens-bridge.ts`                                             | Loopback, token, size, JSON, and strict payload validation remain in place.                                                   |
| Resource cleanup   | PASS   | `src/extensions/trend-finder/components/trend-card.tsx`                               | Copy state resets on text changes; no new timers/subscriptions introduced.                                                    |
| Mutation safety    | PASS   | `src/extensions/trend-finder/hooks/use-creator-lens-draft.ts`                         | In-flight save guard prevents duplicate writes; save-and-run tests enforce ordering.                                          |
| Failure paths      | PASS   | `scripts/extensions/trend-finder/collector.ts`                                        | Competitor matching failure emits warning and continues with default non-match metadata.                                      |
| Contract alignment | PASS   | `src/extensions/trend-finder/schema.ts` and `scripts/lib/ai-runtime/trend-analyst.ts` | Browser schema defaults preserve legacy payloads; analyst schema requires new angle fields and fallback fills missing fields. |

# 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/phase27-session09-competitor-lens-and-creator-angle-pack/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.
