Round 2 verification audit for C064

Model: gpt-5

Claim: A Rabi-frequency difference of epsilon ~= 5% is observed on the carrier transition |up> -> |D5/2,mj=+3/2>, which is detuned by ~= 2 pi x 0.9 MHz from the blue sideband of the axial stretch mode.

Source alignment: source/supp_content.tex:125-125 (Supp. Mat. S4)

Prior official verdict: not_verified with failure_reason data_unavailable.

Executable evidence: run.py. Sandbox rerun logs: run.log.

Independent audit: I checked the paper inventory and source context. This claim depends on measured/raw experimental data or device-specific calibration values, and inventory.json records no paper-provided dataset/code artifact. The correct action is not to synthesize data; the data_unavailable verdict is preserved.

Decision: Round 2 verdict is not_verified with failure_reason data_unavailable and limitations ['data_unavailable']. Notes: Paper: eps ~= 5% Rabi-frequency difference on |up>->|D5/2,+3/2>, detuned ~2pi x 0.9 MHz from the blue sideband of the axial stretch mode (omega_m ~= 2pi x 2.4 MHz). The 5% gradient and exact 0.9 MHz placement are MEASURED, device-specific quantities; no paper-provided raw data exists (inventory.json) -> data_unavailable. Sanity check only: 0.9 MHz < 2.4 MHz stretch mode (ratio 0.375); an order-~MHz Zeeman/fine-structure offset between distinct carriers is physically plausible and internally consistent, but not derivable. No data synthesized.
