### Commands Run

* `bun run test` - PASS, 318 test files and 3748 tests.
* `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 --threshold-kb=0 --json` - PASS, `extensions.items["trend-finder"].data` is 14138 bytes against the 1048576 byte boundary.

### Failed Tests

None.

***

## 5. Database/Schema Alignment

### Status: N/A

*N/A because the session introduced no DB-layer changes, migrations, seeds, persisted database schema, hosted storage path, or ORM metadata.*

* [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] `evidenceRationale` or equivalent topic evidence projection defaults safely for legacy payloads.
* [x] A valid AI rationale is accepted only when it references an existing evidence ID cited by that topic.
* [x] A fabricated rationale that introduces unsupported URL, source, date, metric, or source-local claim is rejected by the validator.
* [x] A deterministic fallback rationale exists when the AI runtime is absent.
* [x] Weak analyst-only evidence is omitted from topic rendering without deleting the raw normalized source row.
* [x] Live Evidence to verify and static Brief evidence cards render concise rationale copy.

### Testing Requirements

* [x] Unit tests written and passing for rationale validation, fallback generation, and weak-link omission.
* [x] Schema/view-model/component tests cover legacy defaults, labels, accessibility text, and missing rationale behavior.
* [x] Static Brief export/renderer tests cover escaped rationale output and privacy cleanliness.
* [x] Payload-size check confirms the extension remains under the 1 MB boundary.
* [x] Focused test commands recorded in implementation notes during the implement step.

### Quality Gates

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

## 7. Conventions Compliance

### Status: PASS

| Category       | Status | Notes                                                                                                  |
| -------------- | ------ | ------------------------------------------------------------------------------------------------------ |
| Naming         | PASS   | Rationale helpers, types, and fields use descriptive Trend Finder naming.                              |
| File Structure | PASS   | Script helpers/tests, UI tests, schema tests, and static Brief code are in existing locations.         |
| Error Handling | PASS   | Invalid AI rationale output returns explicit issue codes; weak/missing links produce bounded warnings. |
| Comments       | PASS   | No obvious commented-out code or noisy comments.                                                       |
| Testing        | PASS   | Focused tests live close to the behavior they cover.                                                   |

### Convention Violations

None.

#### Summary

| Area     | Status | Findings |

### Critical Violations

None.

## 9. Behavioral Quality Spot-Check

### Status: PASS

*Application code changed, so the behavioral quality checklist was applied.*

**Checklist applied**: Yes **Files spot-checked**: `scripts/lib/ai-runtime/evidence-rationale.ts`, `scripts/lib/ai-runtime/trend-analyst.ts`, `scripts/extensions/trend-finder/collector.ts`, `src/extensions/trend-finder/view-model.ts`, `scripts/extensions/trend-finder/static-brief-renderer.ts`

| Category           | Status | File                                           | Details                                                                                                       |
| ------------------ | ------ | ---------------------------------------------- | ------------------------------------------------------------------------------------------------------------- |
| Trust boundaries   | PASS   | `scripts/lib/ai-runtime/trend-analyst.ts`      | AI rationale IDs, cited membership, unsafe text, and unsupported claims are validated before scoring/display. |
| Resource cleanup   | PASS   | `scripts/extensions/trend-finder/collector.ts` | No new persistent resources, subscriptions, timers, or connections are acquired.                              |
| Mutation safety    | PASS   | `scripts/extensions/trend-finder/collector.ts` | Topic projection returns new topic objects; raw normalized evidence rows remain preserved.                    |
| Failure paths      | PASS   | `scripts/lib/ai-runtime/evidence-rationale.ts` | Missing, unsafe, unsupported, and weak evidence paths return explicit omission results.                       |
| Contract alignment | PASS   | `src/extensions/trend-finder/schema.ts`        | Browser schema defaults rationale maps, bounded rationale records, and fallback behavior consistently.        |

### Violations Found

None.

### Fixes Applied During Validation

None.

# 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-session05-per-evidence-rationale/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.
