+/// @brief  CCDB-serializable container for stuck (repeating) pixel error records.
+///
+/// Design rationale
+/// ----------------
+/// TTree-based storage is intentionally avoided for CCDB objects because TTree
+/// branches hold internal file-pointer state; serialising an in-memory TTree
+/// via CcdbApi::createObjectImage() can silently drop the last unflushed basket.
+/// A plain std::vector<StuckPixelEntry> has no such issue: ROOT's TClass
+/// machinery serialises it correctly via the generated dictionary, exactly as
+/// it does for TimeDeadMap.
