## Open now

- #46856: \[Fallback\] "Provider returned error" (no status code) classified as unknown → no rate-limit cooldown → fallback resets every turn
- PR #46858: fix(agent): classify 'Provider returned error' as rate_limit in error classifier
- PR #47354: fix(agent): keep OpenRouter provider fallback on cooldown

These items concern how an agent's error classifier handles OpenRouter's 'Provider returned error' message, which has no status code. One issue reports it being classified as unknown, so no rate-limit cooldown applies and fallback resets each turn; two pull requests propose classifying it as rate_limit and keeping the provider fallback on cooldown.
