RE-RUN 22 Oct 2026 of the ORIGINAL 21 Oct synthetic test: control_run/analyze_pairs_iq.py (unchanged, sha256 74e846a9...) on the files make.py wrote 21 Oct 21:15:16-18 EDT (before the 21:15:29 plan commit). The 21 Oct output was never saved; this is the re-run.
make.py plants: fake 156-qubit chip, 800 shots, idle concurrence 0.8-0.1N, loss 0.03 in K=39 readout at N>0, measured-neighbour leak 3%*N/4 per readout (leaked IQ off-cluster, pair concurrence 0 in that shot); K=1 no loss.
