Seal structurally valid · PQC signatures missing or unverified
Hash chain verified, but PQC signature verification did not pass. This may be expected for benchmark archive seals (PQC pre-signing limited to interactive seals in Phase 3).

Sealed payload (summary)

cuquantum_phi_ansatz on GPU statevector · NVIDIA GeForce RTX 5090 Laptop GPU — SIMULATION, not hardware. 24 measured qubits, 4096 shots, transpiled depth 12. No IBM job id: this run did not execute on hardware. Measured: layers 12 · distinct 4092 · top 101000100111011101101001 @ 0.000488. Receipt receipt_cuquantum_24q_12L_1777346366.json, sha256 b3ca1f7a76059d72dcd3781865a99d39125482bccfe4d63de1ee7ffdcb40d302. Ed25519 signature is over the 32-byte hex-decoded seal_hash and verifies against the published key; ML-DSA-87 present. Not anchored to an L2 chain — this is a signed archive receipt, not an on-chain record.
