Executing coursework has silently overwritten a submitted deliverable twice in
this campaign -- TRAK's outputs/output.png and SPD's results_*.png -- and both
times it was found by a later `git status`, not by the run. `course_main` now
snapshots what git sees under the course root before and after `_run`, and
fails with a diff naming the files if anything moved. Gitignored build output
does not show up there, which is why every runner already writes into build/.
Seen failing before being trusted: a stub whose `_run` appends a newline to
TRAK's config.ini exits 1 and names the file; the same stub without the append
exits 0; and a real `./run.sh run Programming/TRAK` still exits 0 after
rendering, because it writes into build/.
The notebook branch was the specific landmine. `nbconvert --execute --inplace`
rewrites the notebook it just ran, and all four notebooks here are tracked with
their outputs. It now executes to a temp --output-dir. That alone is not
enough, though: nbconvert runs the kernel with its cwd set to the notebook's
own directory, so a cell calling plt.savefig('x.png') still writes beside the
notebook. The tree check above is what actually catches that, which is why it
lives in course_main and applies to every course kind rather than to notebooks.
`_have jupyter` was also the wrong probe. jupyter on this machine is a pipx
shim whose interpreter is gone: `command -v` finds it, and running it exits
127. Both the probe and the runner now use `_works`, which runs `--version`.
`./Programming/twm_4/run.sh --probe` reports "needs jupyter" and exit 78
instead of failing confusingly mid-run.
