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. init is a Promise that resolves when the WebAssembly lexer is initialized
  2. initSync() synchronously initializes the WebAssembly lexer
  3. parse(source) extracts static import specifiers with positions and statement ranges
  4. parse(source) identifies dynamic import expressions with positive dynamic indices
  5. parse(source) detects import.meta expressions with dynamic index set to -2
  6. parse(source) parses import attributes with positive attribute index
  7. parse(source) extracts named, default, and renamed export specifiers with local and exported positions
  8. parse(source) detects re-export facade modules where facade flag is true
  9. parse(source) accurately flags hasModuleSyntax for ES module syntax
