Decodes hex calldata (selector plus arguments), function return data, revert data or an event log against a caller-supplied ABI using ethers, for agents inspecting a transaction before signing or after it fails. Handles tuples, nested and dynamic arrays, bytes and strings, and the built-in Error(string) and Panic(uint256) reverts; a strict re-encode check flags trailing bytes, dirty padding and non-canonical offsets. Does not look up unknown selectors, fetch ABIs, simulate the call or judge whether the transaction is safe; a selector missing from the ABI returns unknown.
