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 deep directory structures idempotently without modifying existing contents
- outputFile writes text with custom flag and mode options while creating parent directories
- outputJson writes formatted JSON and readJson parses JSON documents safely
- copy recursively copies directories with custom filter function and respects overwrite options
- emptyDir removes all nested files and subdirectories while retaining the directory itself
- pathExists asynchronously checks whether files and directories exist without throwing
- move relocates directories across paths and supports overwrite mode
- remove deletes files and directories recursively and succeeds silently on non-existent targets
Files

- csx.json
- package-lock.json
