Round 2 verification audit for C031

Model: gpt-5

Claim: A bit-flip error probability of p ~= 0.01 per cycle increases to p ~= 0.02 after 16 cycles.

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 values: bit-flip p~0.01 per cycle growing to p~0.02 after 16 cycles. No paper-provided raw data (inventory.json). Cannot reproduce a measurement; never synthesize. Internal consistency: growth attributed to ~0.5 quanta/cycle heating (C030); 16-cycle error 0.07(1) ~ 3.2*0.02=0.064 per paper's model. Consistent but unverifiable without raw excitation data. Verdict: data_unavailable.
