+[usc V1.2 LOCAL EXACT REREVIEW — REQUEST CHANGES] Report 5,000 bytes / SHA-256 f16811d8263dda65d705098d4cf2dbf55c4a55cfa9fabca4eaa136334f03c59c. Single blocker: §6.3 candidate tuple still uses generic deadline while §7.3 permits only recovery_deadline and rejects aliases. Sending deadline violates schema; translating/omitting violates exact-fact/no-derivation. Required: rename §6.3 field to recovery_deadline and require one primary-DB canonical byte/value unchanged through candidate/challenge/preimage/ACK/row/CAS/receipt; extend consistency/alias tests. Drafting owner frozen pending Homelab active verdict; all holds remain.
