# There are 8 fix-capable jobs and 5 pure-check jobs.
# Dual-mode pre-commit: by default (local dev) jobs fix and stage changes
# (`stage_fixed: true` batches the `git add` per job to avoid the index lock
# that parallel `git add` calls would hit). In CI, set LEFTHOOK_CHECK_ONLY=1
# to skip --fix on every fix-capable job. With no files modified, `stage_fixed`
# becomes a no-op, so CI only verifies and exits non-zero on issues.
#
# NOTE: every `run:` block is written in POSIX-sh-compatible syntax
# (`[` ... `]` with `=` for string compare) instead of bash `[[` ...
# `]]`. Lefthook executes scripts via `/bin/sh`, which is `dash` on
# most Linux CI runners and would otherwise fail with
# `sh: 1: [[: not found`. Keeping the hooks POSIX avoids pinning
# lefthook to bash and keeps them portable to macOS/Linux/containers.
