Access-governance service that evaluates typed evidence and returns bounded assistant response contracts.

Impact: Separates authorization and refusal adjudication from assistant response generation through explicit verdict contracts.

What I built

• Ingests request-local, user-context, and formal credential evidence with deterministic policy admissibility rules.
• Returns typed verdicts such as scoped enterprise allowance, safe redirect, clarification, or refusal uphold.
• Compiles downstream response contracts with explicit allowed and forbidden modes instead of unrestricted allow decisions.

Proof: Run `python3 -m pytest -q`, `python3 evals/runner.py --check`, and exercise `/adjudicate` locally.
