v7.224.0

• T-999: sc / saipen crew is now a mechanically resumable serial circuit over the full built-in crew. Its durable converge_target: crew state is derived from live role, OUTBOX, shared-contract, release and Core evidence instead of a mutable stage counter.
• T-999: shared-contract sync now has receipt-bound ownership, safe regular-file inventory, exact obsolete-path reconciliation and source/read CAS. Spawn establishes that contract first; collect treats a truly empty targeted OUTBOX as a truthful no-op while refusing malformed or non-ready evidence.
• T-999: crew snapshots and finalization close every evidence race found in REVIEW. File/tree/source identities, role packages, pending operations and release receipts are captured before the snapshot barrier and rechecked at APPLY; stale proof writes zero Core bytes.
• T-999: journal recovery now covers directory and missing-file dependencies plus the crash boundary where a target already carries its after-hash. The hostile matrix carries 138 SAICREW controls and the full scenario suite passes.
