dsh-policy-test

Deterministic regression tests for DSH policy decisions.

v0.1 evaluates policy fixtures without calling the protected tool body. It is intended for AgentFuse-style and other DSH pre-dispatch policies where configuration drift can silently turn an expected BLOCK into ASK/ALLOW.

Fixture cases carry tool, args, and expected decision. The runner returns pass/fail results and never dispatches the underlying tool implementation.

AgentFuse integration (the closed loop)

The evaluator adapter plugs directly into @agentfuse/core — the engine behind the dsh-agentfuse pre-dispatch gate. Compile the same PolicyConfig the production gate compiles, and the fixture table becomes a regression lock on the production decision table: policy drift (e.g. a default silently flipped to allow) turns red instead of turning into an unexpected ALLOW.

See examples/agentfuse/ for the adapter, fixtures, and a drift-detection test.

Non-claims

• no physical tool execution in test mode;
• not a sandbox;
• policy adapters must be supplied explicitly;
• passing fixtures do not prove production configuration is identical unless that configuration is what the adapter evaluates.
