>Proof-of-Execution

Every network inference call prints a PoE line:

⬡ node 12  sha256:a3f9c2…  0.0420 $PRLX

The three fields are: the node ID that served the request (matches an on-chain entry in NodeRegistryLocker), the SHA-256 hash commitment binding the request and result identifiers, and the $PRLX credit cost of that call.

The hash is a SHA-256 commitment over the request ID, the result, and the node ID. It proves a specific node produced a specific result. It is not a zero-knowledge proof and does not prove the result is correct; validity is enforced separately through redundant re-dispatch sampling at the coordinator.
