Git skips a hook without the bit and says nothing about it, so the gate
would have reported success by being absent. The API cannot set the mode:
a file pushed that way arrives as 100644.
Issue: #121

Section 10.1 promised pre-push as the blocking gate that replaces pull requests.
The hook did not exist, so the document promised a check that was not there —
worse than saying nothing, because a promise like that gets relied on. Until now
process-gate ran only as the catch-up job in CI, which reports after the code is
already in dev.
The hook skips branch deletions and tags, and for a branch the remote has not
seen it measures from the merge-base with dev rather than from the root, or every
violation committed before the gate existed would make it impossible to pass. A
missing script does not block a push: old checkouts and worktrees have to stay
usable.
gh is optional on purpose. Reading issue status needs the network, and a hook
that cannot work on a train is a hook people switch off; offline it runs what it
can and CI does the strict pass.
The executable bit is the quiet part. Git skips a hook without +x and says
nothing — the gate reports success by being absent. Measured on a real push:
mode 644 produces zero lines from the gate and the push goes through, 755 stops
it. The API cannot set the bit, so install-hooks restores it on every install.
Issue: #121
User-Visible: no
Pushing the hook through the GitHub contents API dropped its mode to 100644.
assertHookMode caught it on the next commit, which is the gate working as
intended — a non-executable commit-msg would simply never run.
Also brings dev in line with the turn-limit fix already on main.
Issue: #116
User-Visible: no
The hook parsed the message path with basename, an external command. Where
it is missing from PATH the substitution yields an empty string, set -e does
not trip on it, and the MERGE_MSG guard silently stops working — a generated
merge commit would then be rejected for missing trailers it cannot have.
POSIX parameter expansion needs no external command and behaves the same in
sh, dash, bash and Git Bash.
