Proof — a real cross-vendor review

1. The plan

The task was a deploy-script dry run and recovery workflow. These are excerpts from the saved PLAN.md, not claims that the proposed implementation was completed:

## Scope

**In scope:**
- Add `--dry-run` flag to deploy script CLI
- Create `.rollback/` directory structure for storing migration state snapshots

### M1 — CLI dry-run mode

Add `--dry-run` flag parsing and execution path that prints planned operations without database writes.

2. The hand-raise that changed it

The validation report records this concern from the read-only Indexer to the Drafter:

“PLAN.md uses '# Scope' instead of required '## Scope' heading level, which may fail schema validation on /freeze.”

The journey log records “Admitted; indexer elaborated” and a saved plan changing from 3,283 to 3,284 bytes. The final artifact contains the corrected heading:

- # Scope
+ ## Scope

This two-line comparison illustrates the correction described by the report; the evidence bundle retains the final plan, not a separate before-version snapshot.

3. Freeze produced an assignment manifest

After the Brainstorm, /freeze emitted a 7,877-byte EXECUTION.md. The first task includes a role and an acceptance gate:

## Phase 1: M1 — CLI dry-run mode

### Task 1.1
- **Assigned role:** drafter
- **Inputs:** PLAN.md § Milestones / "M1 — CLI dry-run mode"
- **Acceptance gate:**
  - Running `./deploy.sh --dry-run` prints all migration steps with `[DRY-RUN]` prefix and exits zero without touching the database.
- **Dependencies:** none

The same phase also assigned read-only review and cross-file impact assessment. Emitting these assignments is demonstrated here; running and completing them is not.

What this run does and does not prove

The applied raise was a CONCERN. A later BLOCKER was dismissed by the test driver. No Brainstorm BLOCKER pause/resume occurred, so those automated evidence rows remained incomplete. This is evidence of cross-vendor review changing a saved plan, not an all-green result for every possible interruption path.

The plan’s role descriptions did not fully match the live seat assignments; provider attribution above follows the validation seat map. These artifacts are useful precisely because their limits remain visible.

Building with the orchestra

A separate Self-Build Test exercised AI Orchestra against its own repository. The next proof-of-concept goal is to have the extension’s team build its own Co-Work chat web app. These journey artifacts do not establish that the web app has already been built by the extension.
