Round 2 verification audit for C030

Model: gpt-5

Claim: High heating rates add ~= 0.5 motional quanta per cycle on a 1 MHz center-of-mass mode, increasing a correlated bit-flip error during drive (A) as the protocol progresses.

Source alignment: source/main.tex:155-155 (Experimental error analysis)

Prior official verdict: not_verified with failure_reason data_unavailable.

Executable evidence: none. Sandbox rerun logs: none.

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: Measured value: ~0.5 motional quanta added per cycle on a 1 MHz COM mode. No paper-provided raw data (inventory.json). Cannot reproduce a measurement; never synthesize. Sanity check: cycle time ~190 us (3 ms/16), so 0.5 quanta/cycle => ~2.6 quanta/ms heating, a high-but-plausible surface-trap rate consistent with C037's ~100x-cryogenic statement. Not verifiable without the measured data. Verdict: data_unavailable.
