Dynamic model routing: cheaper LLM calls, audited per-request

Yesterday we landed dynamic model routing in LineageLens: the proxy now classifies requests (simple / standard / complex) using deterministic rules and rewrites the model to a cost-appropriate upstream while recording the decision on every provenance record. The key tradeoff we made: no model fallbacks and no cross-provider routing in v1 to keep correlation and auditability intact. Curious how teams would like routing policies surfaced in CI/PR checks — policy-as-code or dashboard toggles?
