+# Optimization Backlog
+
+## Progress Contract Frontend Consumption
+
+- Status: pending
+- Priority: medium
+- Context: The backend now returns `progressSource`, `stage`, `startedAt`, and `expectedDurationMs` on generation task status payloads. The frontend progress UI currently still derives these values locally from message state and static defaults.
+- Follow-up: Wire the backend task progress contract through `aiGenerationClient`, task/message view models, and the progress card components so model-aware `expectedDurationMs` and real provider progress can be consumed end to end.
+- Boundary: Keep this separate from the task store consolidation. The store consolidation is complete without requiring these fields because `WebGenerationPreviewTask` is not the source for Workbench progress cards.
