Two fixes for clean local builds:
1. journal/.latexmkrc — sets pdf_mode=1, max_repeat=5,
silence_logfile_warnings=1, force_mode=1. Without this, latexmk
bails on first-pass undefined-reference errors before getting to
the second pass that would resolve them. Standard issue with
pdfLaTeX in nonstopmode.
2. Replaced the literal U+1F98E lizard glyph in
2026-04-20-evening-mega-session.tex with a textual description.
pdfLaTeX with default inputenc can't render U+1F98E; XeLaTeX or
LuaLaTeX could but switching toolchains is a bigger change than
the issue warrants. The lizard stays in markdown / Pluto where
it works fine.
Final state: 26 pages, 744 KB, no Reference/LaTeX/Unicode errors in
the log.

Records the journal scaffold + retroactive-entries + Julia migration
+ Pluto app work, with \apass{} markers for content that should be
expanded in a later A-pass. Keeps the discipline going from the
night the journal stood up.
Easter eggs:
- ASCII reactor + primary loop in journal/README.md (subtle, shows
where Q_sg flows in as a disturbance).
- Garden-lyric reference embedded in pke_params.jl docstring
("looks ordinary on the surface but is something else underneath")
— same lyric as the preamble.tex comment, referencing the name
behind Split. Hacker-Split's signature.
- 🦎 in the Pluto notebook header + closer.
Nothing functional, nothing that clutters the substance.

journal/ directory, LaTeX-based, dated entries, callout boxes for
derivations / decisions / dead ends / limitations, plus an \apass{}
macro for in-line markers when a later deep-pass is needed.
Retroactive A-style entries for 2026-04-17 (controllers, linearization,
LQR, operation-mode linear reach, Lyapunov barrier) and 2026-04-20
(predicates restructure into deadbands+safety+invariants, OL-vs-CL
barrier analysis, mode-obligation taxonomy, heatup-rate-as-halfspace,
mode_boundaries, first Julia nonlinear reach attempt).
Both entries include derivations written out in math, dead-ends I
hit, code snippets with commentary, figure embeds, and terminal
output where it changed what we did next. The goal is invention-log
depth — readable 4 years from now without the git history to help.
journal/README.md documents the conventions. journal.tex aggregates
all entries into one PDF via latexmk.
Kept claude_memory/ separate as per earlier agreement — those are
short AI-context notes, different audience.
