Struct RoutingRules 

pub struct RoutingRules {
    pub enabled: Option<bool>,
    pub aliases: BTreeMap<String, String>,
    pub tiers: BTreeMap<String, String>,
}

[proxy.routing] — the active router’s rule set (enterprise#13).

Two mechanisms, both within-shape in M1 (the target must speak the same wire dialect as the request; N×M shape translation is M2):

• Aliases: exact requested-model → target. Lets an org expose stable names (acme/fast) or transparently swap one concrete model for another.
• Tiers: intent-based downgrade. The request’s last user message is classified (intent_router); the resulting tier (fast|standard|premium) picks a target from this table. An absent tier key (or "") keeps the requested model — premium work is never silently downgraded unless the operator says so.

A target is "model" (swap the model, keep the upstream) or "provider:model" where provider is a [[proxy.providers]] registry id or a built-in (anthropic|openai|gemini) — then the request is also re-targeted to that provider’s upstream.

Fail-open by construction: any lookup/classification/validation miss routes nothing and forwards the request unchanged.

Fields

enabled: Option<bool>

Master switch; false/absent = passthrough (no body rewrite at all).

aliases: BTreeMap<String, String>

Exact model-name aliases: requested model → "provider:model" | "model". BTreeMap for deterministic iteration/serialization (#498).

tiers: BTreeMap<String, String>

Intent-tier targets: fast|standard|premium → "provider:model" | "model" | "" (= keep requested model).
