# Wraps the skill's offline hooks-contract verifier (scripts/validate-hooks-json.py),
# which lints a hooks.json / settings.json hooks block against the 30-event Claude
# Code hook catalog. Contract (py_compile + --help), offline happy path against
# the shipped skill (assets/hooks.json.template, stripped of its JSONC comments
# exactly as the template's own header instructs — "STRIP EVERY COMMENT"), the
# --json §7 envelope, and a NEGATIVE proving the verifier rejects an unknown
# event (exit 10, names the event). The verifier is structural-only by design;
# there is no --live mode to avoid.
#
# Usage:   bash tests/run.sh
# Exit:    0 all pass, 1 one or more failures
