# ADR-265 D1 — the npm-package gate.
#
# Every Node package in this repo (published or private) gets: install, build,
# tests, a version-literal gate (D3 — package.json is the only place a version
# lives), a pack-content gate (no source maps, unpacked-size budget), a
# tarball-install smoke test (would have caught ADR-264 F1's broken `require`
# export), and the claim-check honesty lint on the README (D4).
