Responsibility-scoped tests
Each policy-bearing layer is checked against its own obligation instead of being treated as an equivalent copy of another layer.

Definition
What PolicyStrata does
PolicyStrata is an open-source regression-testing framework for policy drift in LLM data-agent stacks. It checks whether manifests, validators, compilers, database controls, and release filters preserve the responsibility assigned to each layer.
Audience
Who it is for
PolicyStrata is for teams that operate governed data agents and need repeatable evidence that authorization, semantics, lineage, containment, and release behavior still agree after a policy, schema, or model-facing surface changes.
Capabilities
Deterministic benchmark
DataPolicyDriftBench covers seeded, generated, held-out, and clean-control suites that can run without an LLM API key.
Minimized witnesses
Failures produce smaller reproducible cases that identify the first violated transition.
How the work stays reviewable
Clean controls
The benchmark includes unchanged configurations so a detector must avoid false positives as well as find injected faults.
Explicit limits
Published results are described as coverage of the implemented fault model, not recall on unknown production failures.
Reproducible artifacts
The repository, paper, PDF, benchmark traces, and artifact kit expose the material behind the reported result.
