All 44 directories now probe: 38 runnable, 5 no-code, 1 blocked (ENUME needs
MATLAB or Octave, neither of which is on this machine).
The runners are stubs over one shared scripts/course_lib.sh rather than 44
copies of the logic, for the same reason the gates live in ~/utils. A stub
passes its kind as ARGUMENTS -- course_main --kind python --entry ... -- "$@"
-- rather than setting globals, because globals a linter cannot see being read
mean SC2034 on every one of them, and the only cure would be 44 disables.
Fixed along the way:
- Generating the stubs overwrote Programming/PSD/run.sh, the original
coursework runner. Restored, and given a --probe early exit instead so it
is otherwise untouched: it installs packages with sudo and starts Kafka,
which is exactly what a probe must not trigger.
- The probe guard only recognised runners containing the literal --probe, so
the new stubs (which delegate to the library) all read unprobed. It now
also accepts delegation to course_lib.sh.
- Blocked probes reported "unknown" because _require_any prints the tool it
found, so probes redirected its stdout -- swallowing the failure reason
too. Split into _probe_any, and ENUME now says exactly what it needs.
- shellcheck runs with -x so it follows the sourced library; without it every
stub reports SC1091 and the only alternative is a per-file disable. The
library itself carries `# shellcheck shell=bash` because it has no shebang
on purpose -- it is sourced, never executed.
Then EADS was actually run, and three of its six C++ files did not compile:
- lab3.cpp: copyDictionary was declared taking Dictionary* but its body used
Node members, and the copy constructor called copyTree(), which does not
exist. The copy also dropped key and balanceFactor. Now compiles AND runs,
printing its AVL tests.
- MidTerm/task2.cpp: a const mismatch between declaration and definition, a
stray semicolon before a function body, findNode calling a Tree method on
a treeNode*, and a while loop that never advanced. sumNodeSub also had no
base case -- unreachable before, because the const mismatch meant its body
was never compiled.
These compiled years ago because older GCC did not diagnose uninstantiated
template bodies. Fragments with no main() are now type-checked with -c rather
than linked, since two of these files are exam answers, not programs.
Binaries go to a gitignored build/ -- an extensionless executable dropped next
to its source is not something .gitignore catches by name.

Untracked (--cached, so they stay on disk): 76 LaTeX artifacts, 7 .xdv XeTeX
intermediates, 18 -eps-converted-to.pdf from epstopdf, 32 files of .NET
obj/Debug/net6.0 output including three copies of lab2.dll, 16 .class/.o, the
9 MB Nx cache with its native .node, and an entire committed Python
virtualenv at ECOTE/program/ecote (python 3.10.10, 18 files).
The existing 407-line LaTeX .gitignore was NOT unused as I first assumed --
it already covered *.aux and *.class, and the artifacts simply predate it. So
this appends the categories it missed (*.o, obj/, .venv/, .nx/, target/)
rather than rewriting something that was working.
The second half is the more interesting bug. Auditing with
git ls-files | git check-ignore --stdin --no-index
found 130 files that were tracked AND ignored. That combination fails
silently: `git add` on such a file is not an error, the edit just never
lands. Causes were dist/ swallowing the vendored jQuery/Bootstrap bundle,
.vscode/ and .idea/, and -- the good one -- the LaTeX template's man-page
patterns *.[1-9] and *.[1-9][0-9] matching EPFU's date-named report
directories, so doc/21.11/ read as a man page section and took report.pdf
and seven screenshots with it.
32 of those 130 turned out to be more build output and were untracked too;
the rest got targeted ! overrides. The first attempt used a blanket
!NotProgramming/EMISY/** which re-enabled that course's own LaTeX artifacts,
so it is narrowed to the *.1 schematic exports that actually needed it.
TRAK's nested .gitignore excluded the .vscode DIRECTORY, which stops git
descending, so no root-level ! can reach inside -- that one had to be fixed
at its source.
Both invariants now verified: 0 tracked files ignored, and 0 of the 189
untracked artifacts leaked back into view.
