pre-commit

#!/bin/bash
# =============================================================================
# 3d-cli REPO-DEV pre-commit gate (TRACKED source of truth).
#
# Runs the repo's own Python dev gate before each commit: ruff -> pytest -> mypy.
# Prefer `dev run test` (the primary runner surface). If the external dev CLI is
# unavailable or cannot execute the repo script, fall back to the literal
# rig.yaml scripts.test command. The commit is blocked if any step fails or no
# runner can execute checks.
#
# This is DISTINCT from the `3d init` user-facing template
# (assets/templates/pre-commit): that one gates a *user's* .scad project via
# `3d check`. This hook gates THIS repo's own Python source. Both can exist;
# they live in different repos and never collide.
#
# Install into .git/hooks/pre-commit with: scripts/install-dev-hooks.sh
# Bypass (rare, discouraged): git commit --no-verify
# =============================================================================
