reach_heatup_pj_tight_full.mat now has per-timestep envelopes (Tc_lo_ts, Tc_hi_ts, Tf_lo_ts, ..., rho_lo_ts, rho_hi_ts) for 12932 reach-sets over 300 s, 200s wall time. plot_reach_tubes.jl produces four-panel overlay figures for both operation and heatup PJ modes. Two figures saved: docs/figures/reach_operation_tubes.png (operation LQR) docs/figures/reach_heatup_pj_tubes.png (heatup PJ tight entry) Each shows: - T_c / T_hot / T_cold tubes overlaid on one axis - ΔT_core = T_hot - T_cold (power proxy; right axis MW) - rho envelope in dollars, ±1$ prompt-critical lines - n envelope Finding worth flagging: heatup PJ tight tube shows rho in [-0.25 $, -0.05 $] throughout — always subcritical. The controller is driving rho negative because T_ref starts at T_standby=275 but X_entry has T_c in [285, 291]. So the ramp reference is BELOW the current T_c and the FL controller commands cooling. n decays from [0.001, 0.002] to near zero. PJ validity trivially satisfied (rho stays well below +beta). But the physics being captured is "plant cooling back to ramp reference," not "plant heating to operating temp." For a real heatup tube we'd need ref.T_start aligned with X_entry's T_c midpoint, or X_entry pinned at T_standby. Logged as apass in journal for next pass; morning's priority list (polytopic/SOS barriers, Tikhonov bound) takes precedence. OVERNIGHT_NOTES.md flags the blocked remote push — gitea URL is agent-inferred from submodule submodule.thesis.url pattern, harness (correctly) refused the exfiltration risk.
