peaked-circuit-landscape: analysis code, verification logs, and figures

Companion code archive of the manuscript "The optimization landscape of peaked-circuit generation" (Ilyes Jamoussi). It holds the analysis scripts, the logs they produced, the figure script, and the two pre-registrations the manuscript cites.

analysis/verify_claims.py recomputes 311 of the manuscript's quoted numbers from the raw archives and reports zero disagreements. figures/make_figures.py regenerates all six manuscript figures from the archived ensembles, including Figure 1.

This version corrects how the published points of Ref. [Aaronson and Zhang] Fig. 3c are read. The previous intensity centroid mixed the fitted line into the marker blob and sat below the true center by up to 9 percent, more than the reading error those points carry. Each marker is now located by a triangle-template fit on its per-row color width, and the data point is the center of the fitted extent. The digitized series moves to 0.728, 0.512, 0.416, 0.238, and 0.169 over n = 8 to 16, and figures/fig_scaling.pdf is regenerated. This version also adds run fingerprints for the converged grid and the learning-rate floor sweep.
