Run D1 of manual-push mode (BDR-114). `git config --bool --default true
gitflow.autopush` only covered a MISSING key: an unparseable value made
git die with empty output, the `= false` test failed, and every push ran
again. A typo on a work machine silently re-enabled the pushes it was
meant to stop.
- lib/gitflow.sh: `_gitflow_push_off` reads the mode through the lib
verb (`push-mode`); anything but `auto` is push-off, and the verb's
stderr line names an invalid value during start/finish.
- Emitted post-commit/post-merge hooks (POSIX sh, standalone): push only
when the key reads `true` or is unset; `false` exits quietly; any
other result prints one stderr line ("NOT pushed, treated as manual
push mode") and exits 0. Mirrors gitflow_push_mode.
- .githooks/ and githooks/ regenerated files-only through `emit-hook`
(no config read or write; .git/config hash unchanged).
- hooks/unpushed-guard.sh: mode from the lib verb (absolute lib path
resolved before any cd, no temp file); anything but auto is manual;
the SessionStart line names an invalid or unreadable value.
- Tests: gitflow-test T18q block (invalid → start, hook and finish push
nothing and say so; `true` → the hook pushes; emitted hook is
POSIX-clean), unpushed-guard T14 rewritten.
Global: `make link` generates githooks/ from lib/gitflow.sh and sets git's
global core.hooksPath to ~/.claude/githooks, so every repo on the machine
runs the pre-commit protection and the post-commit / post-merge push, even
one that never ran gitflow init. A repo's own local core.hooksPath still
wins, so hooks/session-start.sh calls `gitflow reconcile-hooks` once per
session and rewrites a .githooks/ that lags the lib (LRN-114 automated);
the pre-commit exemption now covers .githooks/** next to .claude/**.
Per-repo opt-outs for a foreign clone: `git config gitflow.protect false`
(branch model) and `git config gitflow.autopush false` (push). Both, and
the GIT_CONFIG_GLOBAL= / GIT_CONFIG= env bypass, are static deny rules.
`make test` and the two suites that commit on main export
GIT_CONFIG_GLOBAL=/dev/null so the machine's global hooks never fire in
throwaway repos. doctor gains "Git hooks" (global setting, githooks/ equal
to the emitters) and "Scratchpad" (warn when TMPDIR sits on a tmpfs with
usrquota: systemd caps each user at 80% of it, which killed two shells
today, BLK-021). Tests: T18h, T19d, T20 (reconcile), T21 (whitelist and
protect opt-out); this repo's own stale .githooks/ refreshed.
Layer C of the plan written after the 2026-09-21 wipe (BDR-095): a reviewer
sub-agent traced `lftp mirror --delete` against a local file:// tree, the
prose tiers named neither lftp nor a local trace, the brief had authorized
it, and four days of commits had never left the machine.
- gitflow: `start` pushes the branch with its upstream, merge targets are
pushed after each merge, and `init`/`install-hook` write post-commit and
post-merge hooks that push every commit as it lands (warn, never block;
GITFLOW_NO_PUSH=1 for throwaway repos). T18 + T19 (installed == emitted).
- hooks/unpushed-guard.sh on SessionStart and Stop: branch ahead of its
upstream, no upstream, or no origin. Non-blocking systemMessage.
- settings.json: static deny for transfer and mirror tools, rsync --delete,
xargs rm, pipe-to-shell, chmod/chown -R, sudo/doas/pkexec, disk tools,
chattr, docker volume drops/prune/--privileged/socket/-v /:, git history
destruction, --no-verify and core.hooksPath; new hard_deny "destructive
tool against a local path, brief carries no user authority"; soft_deny
reworded + discarding uncommitted work; environment records the incident.
- CLAUDE.global.md "Destructive tools & data loss"; the four report-only
agents trace by reading, never by running, whatever the brief says.
- lib/tests/guard-bash.test.sh: executable spec of the PreToolUse guard
(214 cases). The hook itself is not shipped (BLK-022); the spec skips.
