Port pke_params, pke_th_rhs, pke_linearize, and all five controllers
to Julia. sim_sanity.jl reproduces the MATLAB main.m operation-mode
scenario (100%->80% Q_sg step) and matches final state to 3 decimals
across n, T_f, T_avg, T_cold, u.
reach_operation.jl is a stub: ReachabilityAnalysis.jl (LGG09, GLGM06,
BFFPSV18) numerically explodes on the raw stiff system — envelopes of
1e14 K to 1e37 K instead of the known-tight 0.03 K. Almost certainly
a state-scaling issue: precursors C_i ~ 1e5, temperatures ~ 300,
eigvals span 5000x. Diagonal scaling + retry is planned; left for the
next pass since the hand-rolled MATLAB reach already discharges the
operation-mode obligation.
Project.toml pins OrdinaryDiffEq >= 6.111 (the one that precompiled
cleanly on first instantiate). Manifest gitignored.
Hacker-Split: Julia path open, reach side needs a scaling pass.
