eval: the resident model never reaches Praxis either (V-517)

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.

"отметь" is a capture verb) fills `Slots.Fn` with a Praxis capability name.
**These grammars are the only path to Praxis, not a faster one.** Measured
2026-08-05 with the resident model as router (V-517,
`docs/evals/2026-08-05-reach-llm-router.md`): the model alone reaches Praxis
**0/12**, the same as the classifier alone, because nothing in the router
prompt names a Praxis capability and there is no string for it to write.
Through the cascade it is 11/12. Deleting these rules costs every point. Praxis reach
was **0/12 and structurally so**: `handlePraxisAct` compares `Slots.Fn` to a capability
alias, and that slot is filled from the deployment's enabled tool names, which no Praxis
alias is on. Measured **16/30 → 27/30 overall, praxis 0/12 → 11/12, lifecycle 0/5 → 5/5**
