  "description": "The operational half of the v1 routing.config, split out so the confused-deputy disjointness test works at the file level (Gemini review F2). Contains only authority-neutral engine settings — default tier, tier preferences, model/provider selection, latency, and retry logic. This file is on the IN-SCOPE surface: writable on the autonomous loop (Green). It declares NO zone assignments, NO escalation thresholds, and NO approval requirements; those live in routing-authority-v2.",
  "$comment": "The Grove Foundation · GRV-001 2.0 · governance-write-protection-v1 · CC BY 4.0. The v1 single routing.config (which mixed operational and authority-gating fields) is replaced by routing.operational (this file) + routing.authority. Splitting by file makes path-level disjointness sufficient: an operational write can never touch an authority field because they are literally different files.",
