## When to use
Bundled gates before dry-run/apply.

## Workflow
Run `migrate rewrite-manifest --preflight`.
Emit GateResult per gate (manifest, acceptance, path, target, mappingSource, hash, toctou, conflict, occurrence, snapshot).
Any blocking FAIL → STOP.

## CLI bridge
`velinstyle migrate rewrite-manifest <project> --preflight`
