 - **D30 (R-1204).** The agent's re-key (felhom-agent `ae69ad4`) registers the new key on `POST /hosts/<id>/wg` (re-key

   mailed (it is stored, not mailed — review 2026-10-22 night).
 - `scripts/wire_contract_gate.py`: `wireguard.last_handshake_age_s` left the unread list (the hub reads it since 0.166.0).
