This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured.
How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people.

Contract
- Linter.verify validates custom rule options against JSON schema, interpolates report message placeholders, and provides AST tokens and lexical scope through context.sourceCode
- Linter.verifyAndFix applies fix transformations iteratively while preserving non-autofixable suggestions and remaining diagnostics in result messages
- Linter.getSuppressedMessages retains diagnostic records for rule violations bypassed by inline disable directives
- Linter.verify throws a descriptor error when a custom rule reports a messageId omitted from its meta.messages declaration
