SnO 14q GQE+QSCI S4 controls

Reproducible circuit-generator artefacts for H-cGQE vs MatGen-Q on the published SnO (2e,7o) 14-qubit Hamiltonian. This is not an industrial Sn–C resist result, not a 92 eV iodine-edge absorption run, and not a claim that 49/49 determinants or the classical 72.6→21.2 kcal/mol Sn–C collapse are GQE wins.

Companion model card remains a ground-state circuit generator: Ryukijano/h-cgqe-gic2026.

Quantity	Value
gate1_pool_native_pass	true
Sampler	numpy, qsci_backend=matgenq_subspace
Bitstring convention	leftmost char = qubit 0 (11000000000000 HF)
CASCI	−288.10912104 Ha
Smoke-best ΔE	+2.882 mHa (17 dets) vs Demo A +2.869 mHa
Greedy pool union ΔE	+0.953 mHa, 21 dets (< 49 FCI)
Best native 14-char single	pool14q_random_2 +3.934 mHa, 11 dets
HF / frozen 12-char	+6.120 mHa (HF-like; AS correlation)

Mapping fix: Pauli scorer previously used int(bitstring, 2) (LSB-right). CUDA-Q / MatGen-Q use leftmost = qubit 0.

GPU CUDA-Q confirm job 7431345 and 14-char SFT job 7431349 were still PENDING at dump time. No DAPO. No paid QPU.

STOP

No iodine DAPO. No invented methyltin XYZ. Do not score 49/49 dets as a GQE win. Do not write 72.6→21.2 kcal/mol as GQE.
