"""ops-warden coordination worker (WARDEN-WP-0020).

Pulls ops-warden's unread State Hub coordination requests and turns each into a
**plan** of ops-warden actions. This module is the llm-connect-independent foundation
(T1): the inbox client, the plan model, the deterministic ``RuleBrain`` default, the
guardrail allowlist, and the dry-run renderer. The llm-connect brain (T2) and the
executing dispatcher (T3) plug into the same ``Brain`` protocol and ``WorkerPlan``.

Guardrails live here, not in the brain — the allowlist and no-secret invariant are
enforced on every action *regardless* of what the brain proposes, so an LLM (or a
prompt-injected message) cannot widen ops-warden's authority. Dry-run is the default;
nothing executes in T1.
