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. @napi-rs/wasm-runtime exports createContext, getDefaultContext, emnapiAsyncWorkPlugin, emnapiTSFNPlugin, instantiateNapiModule, instantiateNapiModuleSync, MessageHandler, WASI, createFsProxy, and createOnMessage
  2. getDefaultContext returns the default emnapi Context instance with active handle and scope stores
  3. createContext creates an independent emnapi Context instance
  4. WASI can be instantiated with custom args and environment variables
  5. MessageHandler can be instantiated with onLoad and postMessage handlers
  6. @napi-rs/wasm-runtime/fs exports memfs, Volume, fs, and createFsFromVolume
  7. createOnMessage processes readFileSync requests over SharedArrayBuffer messaging protocol
  8. createOnMessage handles errors and reports status 1 with serialized error payload over SharedArrayBuffer
