📐 Proposed Solution Architecture

Approach

Add a temporary exclusion set in handleComboChat that tracks providers that have returned a hard 429. Before evaluating the next target in the combo, check if its provider is in the exclusion set and skip it if true.

Modified Files

File	Changes
open-sse/services/combo.ts	Add logic to track provider failures and skip matching targets.
open-sse/services/accountFallback.ts	Properly bubble up the 429 status.
