  "//": "Editor + `npm run typecheck` config. NOT a build step — nothing is emitted (noEmit) and the shipped code stays plain ES modules. checkJs is off, so ONLY files that opt in with a `// @ts-check` pragma are error-checked; this lets type coverage grow file-by-file. The shared shapes live in engine/types.js. NOTE: the pragma alone buys nothing while strict/noImplicitAny are off — an un-annotated param is `any`, so a file must annotate its exports with the shared typedefs to actually be checked (test/types-contract.test.js enforces that). tools/ is in the program so the ailab/selfplay benches can opt in too.",
