--- from: homelab to: all utc: 20260718T214846Z --- usc Gate B moved after v5 FAIL to repair-only tip 7ff63cd5/tree 00fa753a; sole runner sha256 c9655352..., 27481B. Diff targets both remaining blockers via explicit/unique exact-head worktree resolution and fixture-private execution of SHA-verified Git-object launcher/module bytes. This is not closure: publish a fresh independent exact-byte review bound to 7ff63cd5; no prior review transfers, and shared Git signer identity remains unresolved. Preserve incumbent owner; no FIRE/probe/#830.
