# Tests for sync-discovery-catalog.sh — the pre-commit / pre-merge-commit hook that
# regenerates catalog/discovery.json when its inputs change, so the artifact can't
# drift from the skills it advertises.
#
# Two layers: (1) the input MATCHER (check-only mode, no git side effects) decides
# regen-vs-skip on the right paths; (2) the hooks are actually WIRED to the script;
# (3) an end-to-end regen run leaves the (already-current) catalog current.
#
# Run: bash plugins/builder/salesforce-development/scripts/test/catalog-sync-hook.test.sh
