The root ceremony uploaded the new package before the new code was claimed, and the hub overwrites the current package when the sealed secrets are unchanged: a customer who started the ceremony again and walked away kept a written-down code that opened nothing. Json mode (the FELHOM_ESCROW argv, unchanged) now returns the package (CeremonyOutput v2, PendingUpload); the daemon uploads it at POST /escrow/ceremony/claim before handing out the code. A failed upload is a 502 with the code still claimable; TTL and a new start wait for an in-flight claim upload; no uploader is a 503. Text mode still uploads at once. No sudoers change. Tests TestEscrowCeremony_R978_* (localapi) and the cmd-side defer/delivery/wiring tests, red-proved.
