# Tests for scripts/rename-ai-artifact.sh — rename an .ai artifact (workflow or
# script) across the canonical + mirror trees, rewriting every reference and
# leaving archived session records (history) untouched.
#
# Strategy: build a synthetic git repo mirroring the canonical/mirror layout in
# a temp dir, copy the real script in, and run it there. The script resolves
# the repo root from git, so it operates entirely on the fixture. The verify
# step (workflow-integrity / sync-check) is best-effort and skips when those
# scripts are absent, which they are in the fixture.
