Positive and negative fixtures prove a rule matches the right code and skips comments.
Fixtures & validation
Every new rule needs two small files: one that must match, one that must not.What you will do: drop fixtures under testdata/rules/<rule-id>/, then run make lint-rules.
Negative: the same text only in a comment, or a lookalike that is not the crypto API.
// crypto.createCipheriv is only mentioned in a comment.
Same idea for C: a real RSA_generate_key_ex(...) vs the name only in /* ... */.
Commands
make lint-rulesmake testmake check
Regenerate goldens only on purpose:
make golden
Review that diff. Do not accept it blindly.
make lint-rules currently requires fixtures for the flagship Go RSA rule. Still add positive and negative fixtures for every rule you ship. That is what keeps false positives out of other people’s CI.
