⚡ Bolt: Optimize HistoryGrouper date checking #111
Conversation
💡 What: Replaced repeated `Calendar` instantiations and field lookups inside the history grouping loop with pre-calculated timestamp boundaries for "Today" and "Yesterday". 🎯 Why: The previous implementation performed O(N) Calendar operations (instantiation, `setTimeInMillis`, and `get(FIELD)`) inside the `groupBy` loop. `Calendar` operations are relatively expensive due to field recalculations. 📊 Impact: - Reduces object allocation (Calendar internal arrays) per item. - Changes date checking complexity from O(N * Calendar_Compute) to O(N * Long_Compare) for recent items. - Optimizes the main thread performance during history list rendering. 🔬 Measurement: Verified via code inspection that timestamp boundaries correctly respect local time midnight. The logic remains functionally equivalent to `isSameDay` checks.
