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. buildInterfaceDeclaration constructs an interface declaration AST node with property and method signatures and validates it with isInterfaceDeclaration
  2. buildGenericInterfaceDeclaration constructs an interface declaration with type parameters and extends heritage clause
  3. buildPropertySignature constructs property signatures with optional modifiers and question token
  4. inspectInterfaceDeclaration extracts interface metadata including name, modifiers, type parameters, heritage clauses, and member descriptors
