# Implementation Summary

**Session ID**: `phase01-session01-event-ingest-contract-reconciliation` **Package**: Cross-cutting (`packages/protocol`, `apps/server`, `apps/hooks`) **Completed**: 2026-05-29 **Duration**: 1.7 hours

***

## Overview

This session reconciled `/event` ingest with the current hook payloads and the documented OpenClaw compatibility surface. The ingest contract is now typed, the server resolves `sessionId` aliases, supported hook payloads emit first- class protocol events, unsupported named events stay bounded and opaque, and the docs describe the shipped behavior instead of implying broader parity.

## Technical Decisions

1. **Alias resolution lives at the server boundary**: hooks keep their fire- and-forget behavior, while the server resolves `sessionId` back to the spawned hero id.
2. **Unsupported historical payloads stay bounded**: the server accepts them as opaque `mission_event` frames instead of pretending to support every legacy variant.

***

## Test Results

| Metric   | Value |
| -------- | ----- |
| Tests    | 22    |
| Passed   | 22    |
| Coverage | n/a   |

***

## Lessons Learned

1. Session aliasing needs to be explicit in both the server helper and the hero roster, otherwise later hook payloads drift away from the spawned hero.
2. The safest compatibility path is a bounded opaque fallback, not a broad parser that silently accepts everything.

***

## Future Considerations

Items for future sessions:

1. Continue Phase 01 hardening with hook runtime safety.
2. Keep the remaining session docs aligned with the shipped ingest contract.

## 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-session01-event-ingest-contract-reconciliation/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.
