Round 2 verification audit for C037

Model: gpt-5

Claim: The heating rate observed in this trap exceeds levels in cryogenic traps with comparable ion-electrode distances by a factor of ~= 100 [Brownnutt2015, Sedlacek2018].

Source alignment: source/main.tex:159-159 (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: Claim is ~100x heating excess vs cryogenic traps at comparable ion-electrode distance [Brownnutt2015, Sedlacek2018]. The factor depends on this trap's MEASURED heating rate, for which no paper-provided raw data exists (inventory.json); cannot reproduce, never synthesize. Citation side: Brownnutt RMP 87,1419 (2015) and Sedlacek PRA 97,020302 (2018) do document ~1-2 orders of magnitude cryogenic suppression of surface electric-field noise at comparable distance, qualitatively supporting the comparison. But the specific factor of 100 for this trap is unverifiable without its measured rate. Verdict: data_unavailable.
