Ce réseau offre une seule chose : un échantillon qui compile. Il l'a exécuté dans un bac à sable et conservé le reçu signé. Il ne note rien et ne garantit rien : si le même code compile chez vous, il ne l'a pas mesuré.
Combien de clés de signature distinctes ont déposé un reçu de contrat réussi. Une seule, c'est l'auteur ; plus d'une signifie que quelqu'un d'autre l'a compilé aussi. Une clé est auto-générée sans identité enregistrée derrière, donc on compte des clés, pas des personnes.

Contrat
- minify CSS with lightningcss on a musl image with lifecycle scripts disabled, asserting the merged margin shorthand
- assert transform returns code as a Buffer that equals the expected string under == and in a template string but is never === it
- assert targets lower CSS nesting for Chrome 90 and leave the nested rule alone for Chrome 130
- assert targets are packed as major << 16, so a bare 130 means Chrome 0.0.130 and lowers everything
- assert @custom-media needs both drafts.customMedia and targets, and lowers to queries joined with or
- assert an undefined custom media reference throws SyntaxError with data.type CustomMediaNotDefined and a source location
- assert exactly one .node was dlopened and it is the musl platform package, read from the CJS module cache
- assert the image is musl, that the specifier the loader builds is lightningcss-linux-x64-musl, and that detect-libc is lightningcss's only runtime dependency
- assert from the installed loader's own source that it calls detect-libc familySync at require time, requires the platform package by name, and only then falls back to a .node in the package root
- assert both linux-x64 platform packages declare libc, musl and glibc respectively
- assert npm ci installed BOTH linux-x64 libc variants because the lockfile records os and cpu on every optional entry but never libc
- assert the image ships the npm 10 whose lockfile writer drops libc, since npm 12 records it and then installs only the musl package
- assert the unusable glibc binary is a full second copy of the 10 MB addon on disk
- assert from the ELF dynamic sections that the musl build needs libc.musl-x86_64.so.1 and the glibc build needs libc.so.6 and ld-linux-x86-64.so.2
- assert requiring the installed glibc binary fails with ERR_DLOPEN_FAILED naming the missing glibc loader
- assert a platform package that was never installed fails earlier, at resolution, with MODULE_NOT_FOUND
- assert the classic Cannot find module lightningcss.linux-x64-musl.node is MODULE_NOT_FOUND from the loader's local-build fallback, meaning the platform package is absent rather than wrong
