Running the courses made this machine stutter during a game. That was me:
PORR's suite solves systems up to 10000x10000 and takes every core it is
given, and the pip installs are not cheap either.
A promise to be careful is not a fix, so `run` now executes inside a transient
systemd scope -- MemoryMax=2G, MemorySwapMax=0 (OOM-kill rather than thrash
swap), CPUQuota=200%, nice -n 19, ionice -c 3. Same mechanism the pre-push
hook in testsAndMisc uses. Verified from inside the scope: memory.max reads
2147483648 and cpu.max reads "200000 100000", so the kernel is enforcing it
rather than the script hoping.
RUN_MEMORY_MAX and RUN_CPU_QUOTA override it for a single deliberate run.
Recorded the two courses that still fail: PORR, which will now be OOM-killed
under the cap and needs a smaller default parameter set, and ZPOB, where
latexmk exits 12 from bibtex despite producing the PDF.

Five files were outside README / CLAUDE* / DOCS* / TODO*, and two were over
the 250-line cap. Both gates now pass repo-wide.
Renames: the two lowercase readme.md files, and three documents into DOCS-*.
The AIS requirements doc split at its own boundary into functional (101) and
non-functional (174). The WDWR report split into six numbered sections behind
an index that keeps the original filename, 38-235 lines each; 753 lines of
body plus the 18-line header account for all 771 original lines, so nothing
was dropped.
That WDWR file needed checking before splitting: it sits next to main.tex and
main.pdf and looked like a conversion of them. It is not -- main.tex is
project 25406 and the markdown is project 18402, a different document. So it
is authored content and the split is real work, not churn on a build artifact.
Filled the three empty READMEs and replaced ECOTE's, which was a stale copy of
the root README still claiming the group projects were excluded -- they were
merged in by subtree some time ago.
EOPSY/lab1 turned out not to be the code-free directory the survey suggested:
it has modify.sh and modify_examples.sh. The oddly-named empty files beside
them are the exercise's OUTPUT, committed so the before/after state is
visible, and its README now says so rather than leaving them looking like junk.
CLAUDE.md follows the testsAndMisc structure. Writing it caught a nice one:
the md-naming marker is a biconditional, so quoting the literal removal string
in a non-TODO file fails the gate. The gate was right; the text is rephrased.
