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
- ensureDir creates nested directory structures asynchronously if they do not exist
- ensureFile creates empty files and parent directories if they do not exist
- outputFile writes string data creating parent directories automatically
- outputJson and readJson write and read JSON documents while automatically creating parent directories
- copy recursively copies directory hierarchies with support for custom filter functions
- move moves files and directories across paths with optional overwrite
- emptyDir removes all contents within a directory while retaining the directory itself
- pathExists asynchronously checks whether files and directories exist
- remove recursively removes directories and files without throwing if the target does not exist
