Round 2 verification audit for C033

Model: gpt-5

Claim: Operating at a fixed N=16 cycles corresponds to ~= 3 ms of 729 nm light per shot.

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

Prior official verdict: partial with failure_reason None.

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

Independent audit: I scanned the copied script for imports/shared helper dependencies and reran it through the sandbox. The code is self-contained in this attempt directory and targets the claim strategy: Check 16 cycles x ~165 us/cycle (or the 729 nm-on time per cycle) is consistent with ~3 ms.. I checked the relevant family model rather than relying only on exit status; the rerun is treated as one reproducibility input.

Decision: Round 2 verdict is partial with failure_reason None and limitations ['paper_text_only_reimplementation']. Notes: Paper: N=16 cycles ~= 3 ms of 729 nm light per shot. Reconstructed from quoted timings: drive (A) = two 75 us 729 nm MS pulses/cycle = 150 us/cycle (main line 122; supp line 133), so 16 x 150 us = 2.40 ms. Using the full average cycle time 165 us (main line 122) as an upper bound gives 16 x 165 us = 2.64 ms. Adding shelving (two 729 carrier pulses, supp line 137) and the analysis drive-A round (~150 us) lands at ~2.7-3.0 ms. All within rounding of the paper's one-sig-fig ~3 ms. Capped at partial: exact shelving/analysis 729 pulse durations not fully specified; provenance paper_text_only reconstruction.
