# Implementation Summary

**Session ID**: `phase19-session04-campaign-workbench` **Package**: null **Completed**: 2026-06-26 **Duration**: 1 hour

***

## Overview

Session 04 turned the command-center campaign and task scaffolds into an operator workbench. The server now owns campaign preview, creation, state transitions, refinement, retry, dispatch, queue bridging, expected-revision checks, and idempotency. The web app now exposes campaign and queue controls with bounded product-facing copy, stale-revision and offline feedback, duplicate-trigger guards, and focused tests.

## Technical Decisions

1. **Server manager owns campaign mutations**: Centralizing preview, create, transition, refine, retry, and dispatch keeps idempotency, expected revisions, audit timestamps, bounded failures, and event metadata aligned.
2. **Dispatch queues work without executor claims**: Campaign dispatch creates or links queue entries with `source: "plan"` and plan references, but does not claim executor completion before later executor-family sessions.
3. **Workbench UI stays summary-only in broad rows**: Campaign and queue rows expose bounded titles, summaries, expected results, state, revision, and verification metadata while raw prompt, command, path, terminal, and artifact content remain out of broad surfaces.
4. **Duplicate-trigger guards exist on both sides**: Server managers keep mutation locks and idempotency replay maps, while web API and store helpers prevent repeated in-flight actions and clean keys after accepted updates or failures.

## Test Results

| Metric        | Value                                            |
| ------------- | ------------------------------------------------ |
| Focused Tests | 42 passed                                        |
| Full Tests    | 2721 passed, 1 skipped                           |
| Coverage      | Not emitted by the configured `npm test` command |

Additional quality gates passed:

* `npm --workspace apps/server run typecheck`
* `npm --workspace apps/web run typecheck`
* `npm run typecheck --workspaces --if-present`
* `npm run lint`
* `npm run format:check`
* `git diff --check`
* ASCII/LF validation across changed files

***

## Lessons Learned

1. Campaign behavior should stay behind a single manager boundary so route responses, WebSocket events, queue bridge state, retries, and compensation remain consistent.
2. Queue transitions need explicit action names rather than generic updates when the UI must communicate restore, unavailable, and dispatch behavior clearly.
3. UI workbench controls need both product-facing copy checks and mutation-key cleanup tests because failures can otherwise leave local controls stuck.

***

## Future Considerations

Items for future sessions:

1. Session 05 should merge campaign blockers, guarded actions, permission requests, failed verification, and review gates into the attention surface.
2. Session 06 should add executor registry capability states before dispatch can imply runnable executor-family behavior.
3. Session 10 should own durable workpad, evidence, verification, and artifact detail views beyond the summary-only campaign and queue rows.

## 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-session04-campaign-workbench/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.
