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
- universalify exports fromCallback and fromPromise helper functions
- fromCallback converts callback-based functions to return a promise when called without a callback
- fromCallback rejects the returned promise when the callback yields an error
- fromCallback invokes provided callback function with result when callback is supplied
- fromCallback delivers errors to the provided callback function
- fromPromise converts promise-returning functions to accept node-style callbacks
- fromPromise delivers rejected promise errors to the provided callback function
- fromPromise returns the original promise when invoked without a callback argument
- wrappers preserve the function name and this context of wrapped functions
