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
- assert findUp traverses parent directories asynchronously to resolve the first matching file path
- assert findUp returns undefined when the target file is not found in parent hierarchy
- assert findUp.sync traverses parent directories synchronously to resolve the matching file path
- assert findUp.sync returns undefined when the target file is not found
- assert findUp accepts an array of filenames and matches by order of priority in each directory
- assert findUp with type directory resolves matching directory path instead of regular file
- assert findUp matcher function returning findUp.stop halts directory traversal
- assert findUp.exists and findUp.sync.exists verify whether a path exists asynchronously and synchronously
