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)

phi_gadt_heron on real QPU · ibm_boston (Heron 3, 156q device). 4 measured qubits, 4096 shots, transpiled depth 18. IBM job d7not7q94dqs73evbjm0 (DONE) — resolves in the published 1,605-job Heron corpus at molecule-gen.org/evidence. Measured: L1_from_uniform 1.085449 · chi2_uniform 6797.1797 · top 0010 @ 0.228271. Receipt receipt_ibm_boston_d7not7q94dqs73evbjm0.json, sha256 96519e063c4544765b11a03b9016ee6120b37ce1a2c0e447f00c993aa59c09bd. 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.
