Sample
verify github.com/mitchellh/copystructure.Config in pkg:golang/github.com/mitchellh/copystructure@v1.2.0

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
- copystructure.Config.Copy creates deep copies of nested structs, slices, and maps without mutating the original
- copystructure.Config.Copiers applies custom CopierFunc handlers for designated reflect.Type instances
- copystructure.Config.ShallowCopiers preserves pointer references for registered types instead of allocating new instances
- copystructure.Config.Lock acquires locks on sync.Locker pointer types during traversal and enforces pointer arguments
