Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures. Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments. MIT-0

Contract

  1. compileInMemory compiles valid TypeScript code into JavaScript using createProgram and collects emitted output
  2. getDiagnostics detects type mismatch errors and syntactic issues using createProgram
  3. emitDeclarationFiles generates d.ts declaration files in memory using createProgram
  4. createInMemoryCompilerHost resolves multi-file module imports in memory for createProgram
