# /opt/jest-ctrf so /app stays byte-identical (no manifest/lockfile churn; the
# anti-cheat tripwire on those files stays valid). jest-environment-node MUST be
# co-installed and pinned to the task's jest version (29.7.0): 0.0.11's index.js
# loads dist/environment.js which hard-requires jest-environment-node at module
# load, so an /opt install fails to register as a reporter without it.
