+
+meta:
+  id: episode-infinite-scroll-11
+  feature: episode-infinite-scroll
+  priority: P2
+  depends_on: [episode-infinite-scroll-10]
+  tags: [rss, pagination, data-fetching]
+
+objective:
+- Fetch episodes in chunks with MAX_EPISODES_REFRESH limit
+- Merge new episodes with existing list
+- Maintain episode ordering (newest first)
+
+deliverables:
+- Paginated episode fetch function
+- Episode list merging logic
+- Integration with feed store
+
+steps:
+1. Create paginated fetch function in feed store
+2. Implement chunk-based episode fetching (50 episodes at a time)
+3. Add logic to merge new episodes with existing list
+4. Maintain reverse chronological order (newest first)
+5. Deduplicate episodes by title or URL
+
+tests:
+- Unit: Test paginated fetch logic
+- Integration: Test with real RSS feeds
+- Edge case: Test with feeds having < 50 episodes
+
+acceptance_criteria:
+- Episodes fetched in chunks of MAX_EPISODES_REFRESH
+- New episodes merged correctly with existing list
+- Episode ordering maintained (newest first)
+
+validation:
+- Test with RSS feed having 100+ episodes
+- Verify pagination works correctly
+- Check episode ordering after merge
+
+notes:
+- Use existing `MAX_EPISODES_REFRESH = 50` constant
+- Add episode deduplication logic
+- Preserve episode metadata during merge
+- Handle cases where feed has fewer episodes
