#Formal support and verification matrix

The current matrix is based on the combinations that have actually been run by the public verification chain; unverified versions are not included in the official support range. Node.js needs to distinguish between two layers: Public CI baseline and Default server matrix.

#Public CI Baseline

#Default server matrix

#Default verification method

• Default gate: npm test
• Fast: npm run verify:fast
• Full functional gate: npm run verify:full
• Coverage governance: npm run test:coverage (independent command and mandatory release-preflight stage)
• Matrix: npm run test:server-matrix
• Package self-check: npm run release:preflight
• Private real env: npm run test:real-env:private

#Public verification and private verification boundaries

• verify:fast / verify:full / test:server-matrix / release:preflight are all publicly reproducible verification commands; test:coverage is an independent coverage command.
• npm test now covers smoke / compatibility / unit / integration by default; migrated TypeScript tests are first compiled to .generated/test-dist/test/** and then executed, and independent migration runners are no longer retained.
• test:real-env:private and verify:release belong to explicit opt-in private real environment verification, which requires the operator to inject SSH/Mongo environment variables by themselves.
• GitHub Actions only runs public access by default and does not assume any private SSH/Mongo resources exist.
• probe:server-matrix and test:server-matrix do not downgrade required versions, topologies, drivers, or test combinations to a skip; unavailable and failed states exit nonzero and block release.
