Filed as cast's record of heavy-duty/box#116: a `shopt -s globstar;
files=(bin/* **/*.sh)` sweep never descends into `.github/`, because globs
do not match dot-prefixed names without `dotglob`. cast has no such sweep —
it has no shellcheck step at all. Its only shell gate was
bash -n install.sh bin/cast scripts/*.sh .github/scripts/*.sh
a syntax check over a hand-maintained list. The reported symptom holds
(release-notes.sh and labels-reconcile.sh ship unlinted) but so does every
other script here, and `bash -n` parses without linting: it would not catch
a quoting or unset-variable bug in any of them.
.github/scripts/shellcheck-all.sh now runs `shellcheck -x` over the tracked
tree, from CI and from `npm run check:shell`. The file list comes from
`git ls-files`, not a glob. `dotglob` was measured and does work today —
cast's dependency tree ships zero `.sh` files, so sweeping after `npm ci`
pulls in nothing — but that is a property of somebody else's package tree,
re-decided by every install. `git ls-files` does not depend on it.
Extensionless scripts are matched by shebang, which covers bin/cast without
naming it.
It carries a class check in box#112's shape: the sweep asserts its own list
covers `git ls-files '*.sh'` and fails naming the strays otherwise. Verified
by swapping the derivation for the buggy globstar glob, which reports
exactly the two .github/scripts files.
All eight scripts pass as they stood; the three findings were intentional
($PATH written literally into a profile, advice text in backticks) or a
false positive, and are annotated in place. No behavior changes.
