## 5. Database/Schema Alignment

### Status: N/A

No DB-layer changes were introduced in this session.

### Issues Found

N/A.

***

## 6. Success Criteria

From `spec.md`:

### Functional Requirements

* [x] Subagent spawn and completion protocol types are exported and covered by focused tests.
* [x] Hook handlers emit bounded lineage metadata when current hook data provides usable identifiers.
* [x] Server ingest produces typed lineage updates when identifiers are available.
* [x] Missing, malformed, duplicate, or oversized lineage metadata degrades without crashes or raw sensitive output.
* [x] Existing opaque compatibility behavior remains available for unsupported named events and unsupported subagent variants.
* [x] WebSocket lineage frames expose only compact local graph state and safe summaries.

### Testing Requirements

* [x] `npm --workspace packages/protocol run typecheck` passed.
* [x] `npm --workspace apps/server run typecheck` passed.
* [x] Focused protocol, hooks, server ingest, export, and WebSocket tests passed.
* [x] Manual validation confirmed no lineage response or frame exposes raw prompts, transcript paths, command bodies, tokens, terminal output, or broad absolute paths.

### Quality Gates

* [x] All files ASCII-encoded.
* [x] Unix LF line endings.
* [x] Code follows project conventions.

# 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/phase03-session03-subagent-lineage-and-mission-graph-runtime/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.
