Since BDR-095 `start` sets an auto-pushed upstream, so `git branch -d`
checked "merged into origin/<branch>" (always true, the post-commit hook
keeps it in sync) instead of "merged into develop". T22a proves it: an
unmerged feature with its upstream in sync is deleted by `-d` alone.
- `gitflow_delete` is the single delete path (finish + CLI `delete`):
refuses main/develop (rc 6) and any branch that is not an ancestor of
develop or main (rc 5, `gitflow_merged_into_base`, fail closed when
neither base exists), then `-d` as a second layer. CLI `merged`, `hooks`.
- Fourth generated hook `reference-transaction`: in the `prepared` call,
a deletion of refs/heads/main or refs/heads/develop exits 1, whatever
issued it (branch -d/-D, update-ref -d, rename, script, sub-agent).
`git config gitflow.protect false` opts a foreign clone out.
- `GITFLOW_HOOKS` is the one hook list: write/emit/reconcile, T19d and
doctor.sh (`gitflow.sh hooks`) read it. `.githooks/` and `githooks/`
regenerated with the fourth hook.
- settings.json: static deny on hand `git branch -d/--delete/-dr/-rd` and
on renames of main/develop; hard_deny "Branch deletion by hand"; the
Disarming entry covers all four hooks and `gitflow.*` config; the
protected-branches environment line states the rule.
- Doctrine (CLAUDE.global.md gitflow section), gitflow SKILL (`delete`
op, rc 5/6 rows, common mistake), guard-bash spec T8w flips to deny,
SETTINGS.md, README, CHANGELOG.
- Tests: T22 (12) lib guard incl. the premise proof, T23 (11) hook;
T19 covers the fourth hook. 152/154, the 2 failures are the
pre-existing T16a (gitleaks absent on this host).
Standalone /capitalize /close /prune-memory /reconcile no longer lean on the .claude/** hook exemption when run on main/develop: the aiguillage branches them to chore/* off develop before writing. New chore type (base develop, finish->develop) added to the lib; hook unchanged (chore/* non-protected). Closes the leak where standalone memory work (memory IS the work, no code branch to follow) landed direct on a protected base. 64/64 gitflow-test green, shellcheck clean.
