+## 2026-02-19 Prevent duplicate unchecked notification dialogs
+
+### Decision
+Implement singleton behavior for unchecked notification dialogs (title prefix `⚠️ 미확인 VOC`).
+Allow regular new notifications to open multiple dialogs as before.
+
+### Implementation
+- **notification_dialog.py (lines 4-6, 8-15, 20, 22-24, 59-62, 86, 88-101)**:
+  1. Added class variable `_unchecked_dialog = None` to track open unchecked dialog
+  2. In `__init__`: Check if incoming title is unchecked notification (startswith `⚠️ 미확인 VOC`)
+  3. If unchecked AND one already open → lift() and focus_force() existing dialog, return early (no new instance)
+  4. If unchecked AND none open → store reference in `_unchecked_dialog`
+  5. Modified close button (line 61) to call `self._on_close()` instead of `self.destroy()`
+  6. Added `_on_close()` method (lines 97-101): Cleans up `_unchecked_dialog` reference before destroying
+  7. Updated `_on_view()` and `_on_open_list()` to call `_on_close()` instead of direct `destroy()`
+
+### Behavior
+- **Unchecked dialogs (⚠️ 미확인 VOC)**: Maximum one open at a time; new attempts bring existing to front
+- **Regular notifications (신규 알림)**: Unchanged; multiple can open (checked in title prefix)
+- **Cleanup**: Reference cleared when dialog closes via any path (button, protocol handler, or methods)
+
+### Why This Approach
+- **Minimal scope**: Changes only notification_dialog.py, no controller/scheduler modifications
+- **Non-intrusive**: Regular new notifications unaffected; only unchecked notifications deduplicated
+- **Safe cleanup**: `_on_close()` ensures `_unchecked_dialog` ref cleared regardless of close method
+- **Semantic check**: title.startswith("⚠️ 미확인 VOC") is the exact prefix used by notifier
+
+### Verified
+- Syntax: python -m py_compile passed
+- No regressions: All button callbacks still work (updated to use _on_close)
+- LSP: Only pre-existing MAIN_COLOR hasattr error (unrelated)

+## 2026-02-19 Fix: HistoryDialog Title Click Checked Timestamp Refresh
+
+### Issue
+When clicking a title in HistoryDialog to open detail view, `controller.mark_as_read(voc_id)` is called which refreshes `controller.list_window`. However, UIManager independently manages `self.list_window`, causing a mismatch—the refresh affects the wrong instance.
+
+### Root Cause
+Two separate list_window references:
+- `controller.list_window` (checked in mark_as_read)
+- `UIManager.list_window` (actual active window displayed)
+
+These never synchronized, so refresh refreshed a stale reference.
+
+### Solution
+**File**: `app/controllers/ui_manager.py` (line 97)
+**Change**: After creating HistoryDialog instance in UIManager, synchronize it to controller:
+```python
+self.list_window = HistoryDialog(self.controller, formatted)
+# UIManager의 list_window를 controller가 접근하도록 동기화
+self.controller.list_window = self.list_window
+```
+
+### Impact
+- Title click → detail open → `mark_as_read()` → `controller.list_window.refresh_data_only()` now refreshes the visible list
+- Checked timestamp visibility updates immediately (same behavior as pressing refresh button)
+- No code changes needed in controller.py; list refresh flow remains unchanged
+- Minimal 1-line addition with clear Korean comment explaining synchronization
+
+### Verification
+✓ Syntax valid (py_compile)
+✓ No LSP diagnostics
+✓ Controller mark_as_read() logic preserved
+✓ Existing list open behavior unaffected
