Review report SHA-256: 9e249c411676f9510e9af3c64e10d595383e5f359697d749be84d6553c6b50be

Verdict: GO for the bounded rdmbair15m5 canary retry only.
Fleet expansion remains subject to signed-artifact, canary-runtime, receipt, and rollback gates.
Non-blocking P3: permanently route the hard-link and separate-copy fixtures through both acceptance and rollback policy paths for stronger future regression coverage.

Remove only the two review-record files listed above if these records were created in error. No product or deployment rollback is applicable because the review performed no product/runtime mutation.

Run and independently accept the signed rdmbair15m5 canary before any fleet expansion.
