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. package manifest declares src/hfs-types.ts types entrypoint, module type, and node engine requirements
  2. declares HfsImpl interface with asynchronous bytes, write, append, isFile, and isDirectory file operations
  3. declares HfsImpl directory management methods including createDirectory, delete, deleteAll, and async iterable list
  4. declares HfsImpl metadata inspection and file transfer methods including size, lastModified, copy, copyAll, move, and moveAll
  5. declares HfsDirectoryEntry and HfsWalkEntry interfaces with path, depth, name, isDirectory, isFile, and isSymlink properties
  6. runtime implementations conforming to HfsImpl contract fulfill in-memory file lifecycle, directory traversal, and entry hierarchy semantics
