+## 2026-08-25 - [List Truncation Context]
+**Learning:** [When displaying dynamic lists in terminal UIs (such as those using ink), if the list is truncated to fit constraints (e.g., a maxVisible limit), always include an explicit visual indicator (like "... and X more tasks") to preserve user situational awareness.]
+**Action:** [Ensure lists have a count indicator when sliced by limits so users realize they are missing content.]
