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.

Contract
- ensureSymlink creates symbolic links across paths and creates parent directories automatically
- ensureLink creates hard links to existing files and creates parent directories automatically
- outputJsonSync and readJsonSync write and read JSON documents synchronously creating parent directories
- outputFileSync writes file content synchronously creating parent directories automatically
- ensureDirSync creates nested directory structures synchronously if they do not exist
- emptyDirSync synchronously deletes all contents within a directory while keeping the directory intact
- pathExistsSync synchronously tests whether a path exists in the file system
- copySync synchronously copies files and directory structures with custom filtering
- removeSync synchronously removes directories and files without throwing if the target does not exist
