# Implementation Summary

**Session ID**: `phase05-session05-federation-event-redaction-and-cockpit-integration` **Package**: Cross-package (`packages/protocol`, `apps/warroom`, `apps/web`) **Completed**: 2026-05-30 **Duration**: 0.4 hours

***

## Overview

This session shipped the redacted War Room federation path for Phase 05. The shared protocol now defines the allowlisted remote event families and rejects blocked sensitive payloads, the Worker persists only validated frames and uses sender-excluded fan-out, and the web cockpit derives outbound redacted frames while rendering remote context in a dedicated overlay and panel summary.

The closeout also updated the Phase 05 tracker, the master PRD status map, the session spec metadata, the project patch version, and the package README boundary notes so the repo now reflects Session 05 as complete and validated.

## Technical Decisions

1. **Protocol-first federation**: The redacted event allowlist lives in the shared protocol package so the Worker and web client consume the same validation rules.
2. **Dedicated remote context**: Remote War Room data stays separate from local hero truth, replay persistence, exports, notifications, adapters, and settings.
3. **Fail-closed payload handling**: Unknown fields, invalid enums, and blocked sensitive keys are rejected before persistence or browser consumption.

***

## Test Results

| Metric   | Value |
| -------- | ----- |
| Tests    | 2035  |
| Passed   | 2034  |
| Coverage | N/A   |

Focused verification also passed during implementation, including 120 session tests across protocol, Worker, web, replay, and export paths.

***

## Lessons Learned

1. Keeping federation helpers pure makes it easier to test redaction and inbound mapping without a browser or live socket.
2. The remote-context boundary is easiest to preserve when the store owns all cleanup paths, including Worker URL changes and socket teardown.

***

## Future Considerations

Items for future sessions:

1. Session 06 should document deployment environment and diagnostics for the optional Worker path.
2. Session 07 should close out Phase 05 validation, security review, and documentation handoff evidence.

## 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/phase05-session05-federation-event-redaction-and-cockpit-integration/implementation_summary.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.
