# v1.1 node-id scoring: official CTRF reporter for jest
# (github.com/ctrf-io/jest-ctrf-json-reporter). kea is pnpm-managed, so
# installing it INSIDE /app (npm or pnpm) would rewrite the manifest /
# lockfile or mangle the pnpm node_modules layout and poison every model.patch.
# Instead it lives outside the repo and jest loads it via an absolute module
# path (--reporters=/opt/jest-ctrf/node_modules/jest-ctrf-json-reporter).
# jest-environment-node MUST be co-installed and pinned to the task's jest
# version (28.1.3 here): 0.0.11's index.js hard-requires it at module load.
# The git-status check asserts the repo worktree stayed byte-for-byte clean.
