rust-xacml

The fragment is intended to implement policy-based authorization, RBAC, policy construction, and caching. It contains no apparent malicious behavior or supply-chain attack indicators: there are no suspicious sinks such as network, process, filesystem, or secret-access operations. It does contain material authorization and correctness risks, particularly the fail-open DenyOverrides behavior and stale cache reads. The fragment also appears syntactically incomplete and may not compile as written. Review and test authorization defaults, policy-combination semantics, cache expiration, and compilation before production use.
