V-405 measured reach with the classifier only, and the LLM router is the
deployed default, so 16/30 was the floor rather than the shipped behaviour.
TestReachWithLLMRouter scores the same 30 cases with the model, gated on
MAVEN_LLM_URL like TestLLMRouterBaseline.
The open question was whether the model writes a literal Praxis capability
into the fn slot and reaches a service the classifier structurally cannot. It
does not. Praxis is 0/12 with the model alone, exactly what the classifier
alone scores, and all twelve fail the same way: local, empty fn. Nothing in the
router prompt names a Praxis capability, so there is no string for it to write.
So V-516's stage-0 grammars are the only path to Praxis, not a determinism
argument. Through the cascade the model scores 28/30 with praxis 11/12, one
point above the classifier baseline. Hexis is 10/10 either way.
Overreach is 1 in both configurations, under the 4 the harness asserts.
