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.

# Set this repository up for development.

|
#
|
|
# Usage:
|
|
# ./install.sh install tools and wire the git hooks
|
|
# ./install.sh --check verify only; exit 1 if anything is missing
|
|
#
|
|
# Idempotent: a second run reports what is already present and changes nothing.
|
|
#
|
|
# It ENDS by verifying, and fails loudly if the gate is not actually runnable.
|
|
# A warning here would just recreate the bug it exists to prevent: the hooks
|
|
# were absent from this repo entirely, so every "pre-commit passed" claim
|
|
# before now was vacuous.
