# Implementation Summary

**Session ID**: `phase20-session07-file-executor-integration` **Package**: null **Completed**: 2026-06-28 **Duration**: 1.1 hours

***

## Overview

Session 07 integrated the local file mutation manager into executable orchestration surfaces. Guarded file approvals, queue file tasks, and campaign file tasks now mutate real workspace files through manager-owned safety checks, record compact execution evidence, expose rollback metadata where backups exist, and preserve redaction boundaries across broad REST, WebSocket, queue, campaign, drawer, documentation, and browser surfaces.

## Technical Decisions

1. **Protocol-first file executable contract**: Queue file tasks wrap the existing `CommandCenterFileMutationRequest` so server and web consumers share one manager-validated request shape.
2. **Manager-backed readiness only**: File executor capabilities stay unavailable or approved-not-executing unless a `FileMutationManager` adapter is injected and can execute the requested operation.
3. **Coordinator-owned dispatch and rollback**: Queue and campaign file execution both route through `TaskExecutionCoordinator` so execution runs, retries, stale/conflict mapping, and rollback metadata stay consistent.
4. **Compact broad surfaces**: Broad rows and events expose operation labels, path labels, byte counts, backup labels, rollback state, and recovery copy only; raw content and patch bodies remain out of broad product surfaces.

| Skipped        | 1                           |
| Coverage       | Not collected               |

## Lessons Learned

1. File executor readiness needs end-to-end proof across protocol, server, UI, documentation, and browser evidence before user-facing action verbs are truthful.
2. Keeping queue and campaign file execution inside one coordinator avoids drift between direct queue dispatch and DAG-driven campaign dispatch.
3. Redaction checks need explicit tests at each boundary because compact result fields move through protocol parsers, REST responses, WebSocket events, rows, drawers, and docs.

***

## Future Considerations

Items for future sessions:

1. Session 08 should apply the same truthful-action bar to managed agent lifecycle controls.
2. Session 09 should either prove container dispatch as an executable family or preserve explicit unsupported/unavailable wording.
3. Session 11 should re-run privacy evidence across the completed Phase 20 executor families before release closeout.

## 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/phase20-session07-file-executor-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.
