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.

# 2026-04-16 — session wrap, switching to nvim
|
|
|
|
Short capstone note. The substantive work is captured in two earlier notes
|
|
from today:
|
|
|
|
- `2026-04-16-repo-restructure.md` — umbrella repo created, submodules wired,
|
|
CLAUDE.md / README / architecture docs written, claude_memory/ pattern
|
|
established.
|
|
- `2026-04-16-controllers-roughout.md` — plant refactored to thesis naming,
|
|
controller contract locked, `ctrl_null` and `ctrl_operation` built,
|
|
validated live in MATLAB (ctrl_operation cuts T_avg drift by ~47% under
|
|
a 100%→80% Q_sg step).
|
|
|
|
Both notes have the full paths-touched lists.
|
|
|
|
## Last-minute adds
|
|
|
|
- **MATLAB terminal invocation (from `plant-model/CLAUDE.md`):**
|
|
`matlab -nodesktop -nosplash -r "main"` — runs from the terminal, figures
|
|
open in their own windows, drops at `>>` prompt. Use `-batch "main"` for
|
|
headless CI-style checks (no figures shown), or `matlab -r "main" &` to
|
|
launch the full IDE backgrounded.
|
|
- **MATLAB version:** R2025b installed at
|
|
`/Applications/MATLAB_R2025b.app/bin/matlab`. Octave not installed.
|
|
- **One-time gotcha fixed at wrap:** my earlier Write of the thesis-aligned
|
|
`plant-model/CLAUDE.md` silently didn't persist (tool reported success
|
|
but the file held the pre-refactor content on re-Read). Rewrote it at
|
|
wrap time. If this recurs, verify with `Read` after any `Write` on an
|
|
existing file, not just trust the tool's success message.
|
|
|
|
## Repo state at wrap
|
|
|
|
- Initial commit made: see `git log --oneline` in
|
|
`~/Documents/pwr-hybrid-3-demo/`.
|
|
- Submodules at: `thesis/` @ gitea main tip, `presentations/2026DICE/` @
|
|
gitea main tip (note: original `~/Documents/Writing/2026DICE/` still has
|
|
uncommitted local edits that were NOT pulled into the submodule — user
|
|
was warned earlier and deferred).
|
|
- Old folders `~/Documents/fret_processing/` and
|
|
`~/Documents/PKE_Playground/` still exist untouched. Delete whenever
|
|
user is confident the umbrella is right.
|
|
- No remote yet for the umbrella repo. Will need to create
|
|
`gitea.danesabo.com/danesabo/pwr-hybrid-3-demo` and `git remote add origin`
|
|
+ push when user is ready.
|
|
|
|
## What's on deck (for the next session, whichever agent)
|
|
|
|
Per the controllers rough-out note: knock out `ctrl_shutdown` (one line),
|
|
`ctrl_scram` (a few lines + uncertainty later), then `ctrl_heatup` (the
|
|
interesting transitory one — ramp + temperature tracking). Invariants and
|
|
`X_safe` regions come after, explicitly deferred by the user. Do not try
|
|
to verify the whole hybrid system at once — pick one mode, discharge its
|
|
reach-set obligation, move on.
