## 5. Database/Schema Alignment

### Status: N/A

No DB-layer changes were introduced in this session.

### Issues Found

N/A -- no DB-layer changes.

***

## 6. Success Criteria

From `spec.md`:

### Functional Requirements

* [x] Every Session 02 read endpoint has a typed parser and a `useHermes` query or helper.
* [x] Token-gated reads do not execute until the token handshake succeeds.
* [x] Every Session 02 write endpoint has a typed parser and a `useHermesAdmin` mutation wrapper.
* [x] All writes remain unavailable when offline, token-missing, or admin disabled.
* [x] Demo fixtures include connections, profiles, templates, missions, documents, document trash, and chat thread detail.

### Testing Requirements

* [x] Parser tests reject malformed read and write payloads.
* [x] Hook tests cover loading, success, empty, error, offline, and token-failure states for new reads.
* [x] Hook tests cover duplicate write prevention and success-only query invalidation for new writes.
* [x] Focused Vitest commands pass.

### Quality Gates

* [x] All files ASCII-encoded.
* [x] Unix LF line endings.
* [x] Code follows project conventions.
* [x] `bun run typecheck` passes.
* [x] Focused Vitest coverage passes for Hermes parser and hook tests.
* [x] `bun run lint` has unrelated existing failures documented in implementation notes; targeted ESLint for touched files passed.

***

## 7. Conventions Compliance

### Status: PASS

Spot-check outcome:

* Naming and file placement match the existing Hermes conventions.
* Error handling stays within the established `HermesParseError` and query-view patterns.
* Test files follow the repo's existing Vitest and happy-dom structure.
* No commented-out code or obvious style regressions were introduced.

***

## 8. Security & GDPR

### Status: PASS / N/A

* Security: PASS
* GDPR: N/A

No security or privacy findings were identified.

***

## 9. Behavioral Quality

### Status: PASS

Spot-check outcome:

* Trust-boundary checks remain in place for token-gated reads and admin writes.
* Duplicate-trigger prevention is present for mutation paths that can be re-invoked while in flight.
* Failure paths surface structured states rather than silent success.
* No high-severity contract mismatches were found in the session deliverables.

***

## 10. Notes

* Full repository lint still reports existing Prettier issues in `scripts/lib/hermes-admin-bridge.ts`, `scripts/lib/hermes-dev-bridge.ts`, `scripts/lib/__tests__/hermes-admin-bridge.test.ts`, and `src/lib/__tests__/home-transforms.test.ts`.
* Those failures are outside this session's deliverable scope and do not block this validation result.

# 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/phase16-session03-data-layer-demo-fixtures/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.
