## Decision requested

Approve, revise, or reject the exact batch manifest named above. Approval is
limited to `reef-railiance`, `REEF-RAILIANCE-WP-0003`, and
`REEF-RAILIANCE-WP-0003-T04`; it does not authorize assignments, another
repository, or any later fleet plan.

The manifest remains fail-closed: any Git, source-fingerprint, projection, or
plan-seal drift before execution voids the approval and requires a new batch
hash.
