## 5. Database/Schema Alignment

### Status: N/A

No DB-layer changes were introduced in this session.

***

## 6. Success Criteria

From `spec.md`:

### Functional Requirements

* [x] New WebSocket connections receive hydration frames in deterministic order with expected payload families.
* [x] Malformed WebSocket payloads do not crash the server, close healthy sockets unnecessarily, or mutate manager state.
* [x] Supported client messages are schema-validated and continue to emit the expected server events.
* [x] Session exports preserve schema version, deterministic CSV headers, and deterministic JSON top-level fields.
* [x] Session exports avoid leaking avoidable prompt, path, command, token, and sensitive local-field values beyond documented local-only boundaries.
* [x] Archive and replay behavior has tests or explicit retained-risk documentation.

### Testing Requirements

* [x] Server WebSocket tests cover hydration order, malformed input, valid messages, duplicate approvals, and socket cleanup.
* [x] Export helper and route tests cover CSV, JSON, schema headers, invalid formats, redaction, and no raw input echo.
* [x] Web tests cover malformed incoming WebSocket frames, replay decoding, and export download/header behavior.
* [x] Protocol tests cover the client-message union and hydration event expectations.
* [x] Focused Vitest commands pass for touched server, web, and protocol tests.

### Quality Gates

* [x] All files ASCII-encoded.
* [x] Unix LF line endings.
* [x] Code follows project conventions.
* [x] Biome format/lint succeeds for touched files.
* [x] TypeScript typecheck succeeds for touched packages.

***

## 7. Conventions Compliance

### Status: PASS

Spot-check of the touched server, web, protocol, and docs files found no obvious issues with naming, structure, error handling, test layout, or comment style.

***

## 8. Security & GDPR

### Status: PASS/N/A

* Security review found no hardcoded secrets, injection issues, or clear misconfiguration in the session deliverables.
* Dependency audit was not required for this session because no dependency manifests changed.
* GDPR review is N/A because this session did not introduce new personal data collection or third-party transfers.

***

## 9. Behavioral Quality

### Status: PASS

Reviewed the application code paths most likely to show behavior regressions:

* `apps/server/src/ws/handlers.ts`
* `apps/server/src/ws/clientMessageValidation.ts`
* `apps/server/src/lib/sessionArchive.ts`
* `apps/server/src/lib/exportSession.ts`
* `apps/web/src/store/useWsClient.ts`

No high-severity trust boundary, cleanup, mutation, failure-path, or contract-alignment issues were found in the validated changes.

# 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://faction-os.gitbook.io/faction-os-docs/.spec_system/archive/sessions/phase01-session05-websocket-hydration-and-archive-export-privacy/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.
