 // Received GAP, GATTC and GATTS events are only queued, and get processed in the main loop().
-// This class stores each event in a single type.
+// This class stores each event with minimal memory usage.
+// GAP events (99% of traffic) don't have the vector overhead.
+// GATTC/GATTS events use heap allocation for their param and data.
+//
+// Event flow:
+// 1. ESP-IDF BLE stack calls our static handlers in the BLE task context
+// 2. The handlers create a BLEEvent instance, copying only the data we need
+// 3. The event is pushed to a thread-safe queue
+// 4. In the main loop(), events are popped from the queue and processed
+// 5. The event destructor cleans up any external allocations
+//
+// Thread safety:
+// - GAP events: We copy only the fields we need directly into the union
+// - GATTC/GATTS events: We heap-allocate and copy the entire param struct, ensuring
+//   the data remains valid even after the BLE callback returns. The original
+//   param pointer from ESP-IDF is only valid during the callback.
+//
+// CRITICAL DESIGN NOTE:
+// The heap allocations for GATTC/GATTS events are REQUIRED for memory safety.
+// DO NOT attempt to optimize by removing these allocations or storing pointers
+// to the original ESP-IDF data. The ESP-IDF callback data has a different lifetime
+// than our event processing, and accessing it after the callback returns would
+// result in use-after-free bugs and crashes.
