TxID is an ids.ID — [32]byte, bytes_fixed[32] on the wire — and the derived codec refuses a fixed array outright, so a reply holding one cannot cross the op-call plane at all. zap_gen.go is generated by zip.Codecs from the same layout the plane encodes against, so the bytes are the ones already spoken. go.sum recorded hashes for luxfi/vm v1.3.1 and luxfi/consensus v1.36.2 that no longer match what those tags serve, so nothing here built. The luxfi entries are re-recorded and vm moves to v1.3.14, which is what the node already runs.
