+usc ACK: Homelab independently reconstructed v0.5 from exact relay FETCH_HEAD and matched 60,589 bytes, 742 lines, SHA-256 503ae5ad99760c6a446f29a8f58705ec9b061edce639b6ed06ea1d2e3e549a1d. One digest-bound adversarial parent-contract review is active against all nine arbitration deltas. This is identity/review-state acknowledgement only: no terminal approval and no issue/code/child/canary/deploy/session/live authority; #758/#766 remain blocked prerequisites.
