# Implementation Summary

**Session ID**: `phase19-session14-channels-and-scope` **Package**: null **Completed**: 2026-06-27 **Duration**: 3-4 hours

***

## Overview

Completed the cross-package Channels And Scope session for Phase 19. The work adds protocol-backed channel command and scope contracts, server-owned local channel/webhook intake with replay guards, proposal-first conversion into queue, attention, and guarded-action surfaces, adapter source attribution helpers, and web scope controls plus channel command visibility while preserving local-first trust and redaction boundaries.

## Technical Decisions

1. **Protocol-first channel contracts**: Channel source, replay metadata, scope labels, queue source, and guarded-action vocabulary now live in shared protocol contracts before server or web consumers depend on them.
2. **Manager-owned inbound boundary**: Replay protection, validation, source attribution, scope metadata, and conversion behavior live in `ChannelCommandManager` instead of route or UI code.
3. **Proposal-first external input**: External channel and webhook payloads can create visible local queue, attention, or guarded-action proposal records, but trusted automatic execution remains unavailable.
4. **Path-safe scope filtering**: Scope filters rely on safe stored labels and reject absolute, traversal, URL-like, or raw payload values before browser display.

## Lessons Learned

1. Scope filtering must match stored `scopeLabels` strictly; fallback text matching can leak unscoped records into scoped views.
2. Channel health must retain pairing metadata in the route instance so operators can observe configuration changes after pairing.
3. Guarded-action vocabulary tests need to expand with protocol enum changes so new proposal families do not drift from parser expectations.

***

## Future Considerations

Items for future sessions:

1. Session 15 can use channel command replay, scope, and source metadata for notification and metrics rollups without broadening raw payload exposure.
2. Session 16 should preserve the current proposal-first channel boundary when documenting final ergonomics and keyboard flows.
3. GitHub signature verification, hosted identity, trusted remote execution, mobile push, and production channel trust remain no-claim boundaries until separately scoped, threat-modeled, tested, and documented.

## 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/phase19-session14-channels-and-scope/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.
