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.
MIT-0

Contract
- errors.New creates an error with message
- errors.Errorf creates a formatted error
- errors.Wrap annotates an error with message and returns nil for a nil error
- errors.Wrapf annotates an error with formatted message and returns nil for a nil error
- errors.WithMessage adds context message and returns nil for a nil error
- errors.WithStack attaches stack information while preserving error message and returns nil for a nil error
- errors.Cause recursively unwraps nested errors to retrieve the underlying root cause
