+# Fix filename preservation bug when closing/opening issues with modified titles
+
+## Problem
+
+When users modified issue titles after creation, the `close` and `open` commands created duplicate files with malformed filenames:
+
+1. **Korean/Special Character Titles**: Generated malformed filenames like `001-.md`
+2. **Modified English Titles**: Created new files with updated slugs, leaving originals behind
+
+### Root Cause
+
+Both `close` and `open` commands called `SaveIssue()` before `MoveIssue()`, which:
+- Generated new slugs based on current `issue.Title` (which could be modified by users)
+- Created new files instead of updating existing ones
+- Left original files in place, resulting in duplicates
+
+
+---
+
+
+## Solution
+
+1. **Modified `MoveIssue` in `pkg/storage.go`**:
+   - Update `updated` timestamp after successful file relocation
+   - Preserve original filename during move
+
+2. **Removed redundant `SaveIssue` calls in `cmd/close.go` and `cmd/open.go`**:
+   - Eliminated duplicate file creation
+   - Simplified command logic
+
+3. **Added regression tests**:
+   - `TestRunClosePreservesFilenameWithKoreanTitle`
+   - `TestRunClosePreservesFilenameWhenTitleModified`
+   - `TestRunOpenPreservesFilenameWithKoreanTitle`
+   - `TestRunOpenPreservesFilenameWhenTitleModified`
+   - Updated `TestMoveIssue` to verify timestamp updates
+
+## Test Results
+
+- ✅ All existing tests pass
+- ✅ New regression tests pass
+- ✅ Code coverage maintained: 86.7% (cmd), 76.0% (pkg)
+
+## Files Changed
+
+- `pkg/storage.go`: Add timestamp update in `MoveIssue`
+- `cmd/close.go`: Remove `SaveIssue` call
+- `cmd/open.go`: Remove `SaveIssue` call
+- `pkg/storage_test.go`: Add timestamp verification
+- `cmd/close_test.go`: Add filename preservation tests
+- `cmd/open_test.go`: Add filename preservation tests
