Design offline support for the mobile feature described: {feature_description}. Step 1: Classify each data operation in the feature: must work offline, degrades gracefully offline, or requires connectivity; justify each classification by user expectation. Step 2: For offline-capable writes, design the local persistence and outbound queue: what is stored, in what order operations replay, and how the UI represents pending state. Step 3: Design conflict resolution for each write type when the same data changed server-side during offline: last-write-wins, merge, or surface-to-user; justify per data type by the cost of silent data loss. Step 4: Handle sync failures: partial sync, auth expiry mid-sync, and permanent rejections. Step 5: Define the test matrix: airplane mode transitions, kill-during-sync, and clock skew scenarios.
