+# Visual Formatting & GitHub Stats Improvements
+
+## Visual Enhancements ✨
+
+### Tree Branches & File Icons
+All CLI outputs now use consistent tree-based formatting with file icons:
+
+**`dev map` hot paths:**
+```
+## Hot Paths (most referenced)
+  ├─ 📘 **typescript.ts** • 307 refs
+     /packages/core/src/scanner
+  ├─ 📘 **index.ts** • 251 refs
+     /packages/core/src/indexer
+  └─ 📘 **go.ts** • 152 refs
+     /packages/core/src/scanner
+```
+
+**`dev activity` output:**
+```
+├─ 📘 packages/mcp-server/bin/dev-agent-mcp.ts
+│     34 commits • 1 👤 • Last: today
+│
+├─ 📘 packages/core/src/indexer/index.ts
+│     32 commits • 1 👤 • Last: today
+```
+
+### Shared Icon Utility
+Extracted `getFileIcon()` to `@lytics/dev-agent-core/utils` for reuse across packages.
+
+## GitHub Stats Fix 🐛
+
+Fixed confusing issue/PR state display:
+
+**Before:**
+```
+Issues: 68 total (14 open, 55 closed)
+Pull Requests: 97 total (14 open, 96 merged)  ❌ Wrong!
+```
+
+**After:**
+```
+Issues: 68 total (14 open, 54 closed)
+Pull Requests: 97 total (0 open, 96 merged)   ✅ Correct!
+```
+
+- Added separate state tracking: `issuesByState`, `prsByState`
+- GitHub indexer now tracks issue and PR states independently
+- Stats display now shows accurate per-type counts
+
+## Progress Display Improvements 📊
+
+### Detailed Progress with Rates
+All indexing commands now show detailed progress:
+
+```
+Scanning Repository: 1,234/4,567 files (27%, 45 files/sec)
+Embedding Vectors: 856/2,549 documents (34%, 122 docs/sec)
+```
+
+Applied to:
+- `dev index` - scanning & embedding progress
+- `dev update` - changed files & embedding progress
+- `dev git index` - commit embedding progress
+- `dev github index` - document embedding progress
+
+### Update Plan Display
+`dev update` now shows what will change before starting:
+
+```
+Update plan:
+  • Changed: 3 files
+  • Added: 1 file
+  • Deleted: 0 files
+```
+
+### Code Quality
+- Refactored progress logic into `ProgressRenderer.updateSectionWithRate()`
+- Reduced ~40 lines of duplicated code
+- Fixed NaN display (now shows "Discovering files..." initially)
+
+## Bug Fixes 🐛
+
+- **`dev owners`**: Fixed "No ownership data" error when run from subdirectories
+- **Progress Display**: Fixed NaN showing during initial file discovery phase
+- **`dev update`**: Removed duplicate checkmark in success message
+
+## Breaking Changes
+
+None - all changes are backward compatible. Old GitHub state files will fall back to aggregate counts gracefully.
