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.

Two workflows, one per gate, each checking out kuhyx/utils into .utils and
calling the shared script -- the pattern every other repo here uses.
pre-commit.yml sets UTILS_ROOT to that checkout, without which the shims fail
with "shared gate not found", and both use fetch-depth 1 because the history
is ~494 MB and no gate reads it.
install.sh ends by verifying and exits non-zero if the gate cannot run; a
warning there would just recreate the bug it exists to prevent, since this
repo had no hooks at all until now. Confirmed both ways: --check exited 1
while the hooks were missing, then 0 once installed.
run.sh separates `status` (probe, seconds, safe in CI) from `run <dir>`
(actually executes one project). Conflating them is not hypothetical -- the
first version of the probe did exactly that and it cost 120 seconds and a
scare. Some course dirs already ship a run.sh from years ago, and
Programming/PSD/run.sh installs packages with sudo and starts Kafka; calling
it with an unknown --probe flag does not probe anything, it runs the project.
It blocked on a sudo prompt rather than installing (verified against
/var/log/pacman.log and the absence of a yay clone), but only by luck.
So probe_one now invokes a runner ONLY if it declares --probe, wraps it in
`timeout 20s` as defence in depth, and reports anything else as unprobed
without touching it. All 44 directories now probe instantly.
DOCS-runnability.md is generated with a per-environment column. Recording one
global status would make the CI check red by construction, since `runnable`
locally and `blocked` on ubuntu-latest is the normal case for the MATLAB,
Unity and .NET directories rather than a drift signal.
Per-directory run.sh files are the next step; all 44 currently read unprobed.
