chaotic-ring example: more pump points + onset zoom panel
claude

chaotic-ring example: mark newton L-I points (active-set switch reads as data)

harden(salt): single-add active set, threshold bootstrap, Ge regression test
claude
committed

Commits on Jun 12, 2026

line_PRA: reproducible Ge-Chong-Stone Fig. 6 validation

arnaudon
and
claude
committed
line_PRA: clean Fig.6 digitization and one color per mode

arnaudon
and
claude
committed
line_PRA: pin the second-threshold offset to a high-k systematic

arnaudon
and
claude
committed
Remove self_consistent and full_salt solvers; keep linear + newton

arnaudon
and
claude
committed
salt: analytic newton onset scale (replaces the measured probe)

arnaudon
and
claude
committed
examples: one folder per graph + linear-vs-newton mode-profile figures

arnaudon
and
claude
committed
examples: ring_chain (mode count by design) and long_line (multimode FP)

arnaudon
and
claude
committed
examples: mini_buffon dense-spectrum reality check

arnaudon
and
claude
committed
examples: chord_sweep -- density alone does not buy lasing modes

arnaudon
and
claude
committed
mini_buffon: more lasing modes -- pump strength beats pump shaping

arnaudon
and
claude
committed
mini_buffon: diagnose the high-pump per-mode kink (identity swap)

arnaudon
and
claude
committed
salt: harden the newton continuation against wrong-basin solves

arnaudon
and
claude

salt: total-output ratchet removes the high-pump L-I kink

arnaudon
and
claude
committed
docs: CF-state SALT solver design + validated foundation

arnaudon
and
claude
committed
docs(cf): record the CF basis-finding obstacle (Beyn-in-eta fails)

arnaudon
and
claude
committed
salt: full_salt_newton runs on the real buffon (correct the cost claim)
