## 4. Test Results

### Status: PASS

| Metric      | Value         |
| ----------- | ------------- |
| Total Tests | 3837          |
| Passed      | 3837          |
| Failed      | 0             |
| Coverage    | Not collected |

### Commands

* `bun run test` - PASS, 326 files and 3837 tests.
* `bun run typecheck` - PASS.
* `bun run typecheck:scripts` - PASS.
* `bun run lint` - PASS after applying Prettier to session-touched files.
* `bunx prettier --check <session-touched files>` - PASS.
* `git diff --check` - PASS.
* `bunx vitest run ./scripts/extensions/trend-finder/__tests__/static-brief-export.test.ts ./scripts/extensions/trend-finder/__tests__/static-brief-renderer.test.ts ./scripts/extensions/trend-finder/__tests__/static-brief-qa.test.ts ./scripts/extensions/trend-finder/__tests__/measure-payload-size.test.ts ./scripts/extensions/trend-finder/__tests__/required-derived-fields.test.ts` - PASS, 5 files and 37 tests.
* `bun run scripts/extensions/trend-finder/measure-payload-size.ts src/data/live-data.json --threshold-kb=9999 --json` - PASS.
* Static Brief dry run against a validated fixture with security relevance injected - PASS, 15 checked sections, 0 QA issues, 0 security-lens privacy issues.

### Failed Tests

None.

### Notes

The local generated `src/data/live-data.json` predates this session, so payload-size reporting shows `data.topics[].securityRelevance` as a visible 0-byte legacy/missing branch. The Trend Finder browser data payload is 457150 bytes, below the 1 MB extension payload boundary.

## 5. Database/Schema Alignment

### Status: N/A

This session introduced no DB-layer changes, migrations, persisted storage, seed database changes, SQL, ORM metadata, or hosted storage.

### Issues Found

N/A - no DB-layer changes.

***

## 6. Success Criteria

From `spec.md`:

### Functional Requirements

* [x] Security-relevant fixtures classify with severity, reason codes, cited evidence IDs, and named informational action items.
* [x] Non-security fixtures remain `unavailable` and do not publish misleading severity.
* [x] The existing reviewed `security` keyword category is reused without adding or enabling a new source.
* [x] Signal Workbench exposes a security-lens filter and row chips with platform-appropriate accessibility labels, focus management, and input support.
* [x] Static Brief renders a compact security callout and a clear empty state.
* [x] Browser payloads and static Brief output expose no raw article bodies, comment bodies, transcripts, prompts, provider responses, private paths, tokens, credential-shaped strings, or raw source payloads.

### Testing Requirements

* [x] Unit tests written and passing for matching, severity selection, action-item bounds, cited-evidence bounds, deterministic ordering, and unavailable fallback.
* [x] Schema and source-breakdown tests prove legacy defaults, cited-evidence validation, required-field closeout, and safe integration.
* [x] Workbench model/control/table tests prove filtering, row chips, reset on new run payload, and non-security behavior.
* [x] Static Brief export, renderer, QA, and payload-size tests prove rendering, branch tracking, privacy cleanliness, and failure mapping.
* [x] Payload-size and static Brief privacy scans remain green.

### Non-Functional Requirements

* [x] Browser payload stays under the 1 MB extension budget.
* [x] Derivation is deterministic, bounded, and free of new network calls.
* [x] Derivation errors degrade to unavailable output without blocking unrelated Trend Finder output.
* [x] No new source, media, credential flow, database, hosted storage, dependency, shell execution, or third-party transfer is introduced.

### 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

| -------------- | ------ | ----------------------------------------------------------------------------------------------------------------------- |
| Naming         | PASS   | Names use Trend Finder terms and descriptive TypeScript identifiers.                                                    |
| File Structure | PASS   | Runtime, scripts, extension UI, tests, and docs remain in established locations.                                        |
| Error Handling | PASS   | Security derivation errors degrade to explicit unavailable output; schema and static Brief QA fail malformed contracts. |
| Comments       | PASS   | No obvious commented-out code or noisy comments found.                                                                  |
| Testing        | PASS   | Tests are close to covered behavior and full suite passes.                                                              |

### Convention Violations

## 9. Behavioral Quality Spot-Check

### Status: PASS

| ------------------ | ------ | ------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------- |
| Trust boundaries   | PASS   | `scripts/lib/ai-runtime/security-lens.ts`               | Input/options are Zod-validated and derivation only uses existing normalized evidence/source/topic fields.           |
| Resource cleanup   | PASS   | N/A                                                     | No new timers, subscriptions, connections, file handles, or network clients were introduced.                         |
| Mutation safety    | PASS   | `src/extensions/trend-finder/signal-workbench-model.ts` | Security filter is pure model state and stale selections reset when new rows cannot satisfy the filter.              |
| Failure paths      | PASS   | `scripts/lib/ai-runtime/source-breakdown.ts`            | Derivation exceptions return explicit unavailable security relevance without blocking unrelated topic output.        |
| Contract alignment | PASS   | `src/extensions/trend-finder/schema.ts`                 | Schema defaults, cited-evidence validation, required-derived registration, static Brief projection, and tests agree. |

### Violations Found

### Fixes Applied During Validation

* Applied Prettier to session-touched files after `bun run lint` reported formatting issues.
* Re-ran lint, typechecks, full tests, scoped Prettier check, ASCII/LF scan, payload-size reporting, and static Brief dry-run after formatting.

# 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-session12-security-lens/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.
