passes per confirmed member
Seven widths and thirty frozen confirmation seeds per width. Controlled simulation.
diagonal secant at scale
Zero passes at 16,384 and 65,536 controls. It is not eligible for production selection.
cycles to lock
256 to 4,096 simulated wavelength channels, with 0.041–0.058 dB tail error.
Strehl ratio
Locked in six cycles at 128, 640, and 4,096 simulated control pixels.
unitary fidelity
Measured at 4,096 simulated phase controls; 0.9992 at 256 controls.
normalized result
Per-cell sensing reached the 0.95 operating threshold in six cycles.
globally coupled variables
Twenty of twenty fixed and changing-response trials cleared the verified RMS threshold in six acquisitions.
median final error
Controlled response-matching simulation under a fixed six-acquisition budget.
channels tested
Finite differences, SPSA, and CMA-ES matched no control under the same one-read budget. Simulated.
measurements to usable
Zero setup reads at n = 1,024, with every comparison setup and diagnostic read charged to the same budget. Controlled simulation.
channels held flat
From 10⁵ to 10⁸ in the pre-registered controlled-simulation ladder.
controls confirmed
The active default and explicit pilot member each passed 30 of 30 at the largest primary width. Simulated.
resident weights held
Depth eight. 78.6% top-1 agreement versus 65.7% free-running and 70.1% scheduled recalibration. Controlled simulation.
monitored columns
75.4% agreement versus 61.3% free-running and 66.9% scheduled recalibration. Controlled simulation.
Misses beside passes
Predictions that did not survive testing.
More cycles did not always win. Delayed acquisition diverged. Light commissioning was insufficient.
