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. create initializes a new cache instance and tracks file modifications using mtime and size
  2. createFromFile initializes a cache instance from a single file path
  3. hasFileChanged detects new and modified files
  4. getUpdatedFiles filters and returns only files that have changed
  5. analyzeFiles categorizes files into changedFiles, notChangedFiles, and notFoundFiles
  6. reconcile persists file metadata and clears changed status on subsequent checks
  7. removeEntry clears cached metadata for a specified file
  8. deleteCacheFile removes the cache file from disk
  9. destroy clears in-memory state and removes the underlying cache file
  10. create with useChecksum tracks file modifications using cryptographic hash instead of mtime
