 ### Technical Invariants
 - **Fail-Fast Cascade Walk**: Free endpoints on OpenRouter frequently return transient `429`, `503`, or drop out of `/v1/models` without warning. Candidate resolution treats failures as cascade triggers rather than fatal aborts, stepping to the next viable candidate model within `<250ms`.
 - **Sliding-Window Budgeting**: Token usage and request counts are stored in atomic sliding windows (`VecDeque<DateTime<Utc>>`). Router and classifier calls deduct from the shared account budget to prevent downstream API lockouts.
