Dane Sabo cebf8c167a Initial umbrella repo: thesis + FRET pipeline + plant model with first controllers
Folds three previously-separate pieces into one preliminary-example repo
for the HAHACS thesis:

- thesis/ (submodule) → gitea Thesis.git — the PhD proposal
- fret-pipeline/ — FRET requirements to AIGER controller (was
  ~/Documents/fret_processing/; prior single-commit history abandoned
  per user decision)
- plant-model/ — 10-state PKE + lumped T/H PWR model (was
  ~/Documents/PKE_Playground/; never version-controlled before)
- presentations/2026DICE/ (submodule) → gitea 2026DICE.git
- reachability/, hardware/ — empty placeholders for Thrust 3 and HIL
- docs/architecture.md — how the discrete and continuous layers compose
- claude_memory/ — session notes and scratch knowledge pattern

Plant model refactored to thesis naming (x, plant, u, ref); pke_th_rhs
now takes u as an explicit arg instead of reading rho_ext from the
params struct. First two controllers built to the contract
u = ctrl_<mode>(t, x, plant, ref): ctrl_null (baseline) and
ctrl_operation (stabilizing, proportional on T_avg). Validated under a
100% -> 80% Q_sg step: ctrl_operation reduces steady-state T_avg drift
~47% vs. the unforced plant.

Root CLAUDE.md emphasizes that CLAUDE.md files are living documents and
that any knowledge not captured before a session ends is lost forever;
claude_memory/ holds the session-level notes that haven't stabilized
enough to graduate into a CLAUDE.md.
