Conformance

Fixtures live in conformance/<suite>/cases.json and are the executable oracle for every wire rule. scripts/check-conformance.ts guards the files themselves; language tests consume them directly:

  • Bun: packages/errcode/index.test.ts imports the JSON and asserts each case.
  • Rust: crates/search-wasm uses include_str! on the same file for its cargo test.

A normative wire statement without a fixture is draft material and does not ship. When the Rust crate and the TS kit disagree, the fixture is wrong or one implementation is wrong; fix the fixture first, then both sides.
