git writes MERGE_HEAD only after the pre-merge-commit hook returns, so the
gate never found it and aborted every non-fast-forward merge with "No merge
in progress"; git then wrote the merge state via abort_commit(), leaving a
half-finished merge that git status reported as "still merging". The gate
had therefore never verified a single signature.
git also skips pre-merge-commit entirely once a merge conflicts, so the
conflict-resolution commit was unguarded as well. prepare-commit-msg fires
with MERGE_HEAD present on both paths and no-ops on ordinary commits.
Verified in a scratch repo with a real pre-commit install: ordinary commit
passes silently, clean automerge and conflict-resolution commit both block
an unsigned incoming commit, and the extra stash/restore cycle round-trips
unstaged changes byte-identically.
pre_commit install never removes hook types dropped from the config, so the
install script now also uninstalls the stale pre-merge-commit hook.
Move files that share a delimiter-bounded name prefix within a folder (threshold 2) into a subfolder named after the prefix, dropping the prefix from the filename. Covers plugins/filter (docker, generate, has, merge, get/all), env handler subpackages, utils/roles/entity, utils/tests/swarm/write, role SQL/scripts/templates, keycloak/mailu task-includes, shared tasks/utils/load, and CI scripts. Update every import, query_file/script/include_tasks/src/lookup target, compose bind mount, and python -m path to the new locations.
Extend the prefix-grouped-files lint to threshold 2 with dir-level .nocheck and file-head nocheck opt-outs, and skip groups whose shortest member's stem equals the shared prefix. Keep flat only where a loader forbids nesting: WordPress mu-plugins and the docs/requirements namespace. Ansible filter discovery is recursive, so nested filters stay Jinja-resolvable.
