+# Entropy Audit Findings: Data-Oriented Python Optimization Pass
+
+## Phase 5 Status: In Progress
+
+## Issues Found and Fixed
+
+### 1. Duplicate Line Bug in `app_controller.py`
+**Location:** `rag_emb_provider.setter` (around line 541)
+**Issue:** Two identical lines in setter:
+```python
+if self.rag_engine: self.rag_engine = rag_engine.RAGEngine(self.rag_config, self.active_project_root)
+if self.rag_engine: self.rag_engine = rag_engine.RAGEngine(self.rag_config, self.active_project_root)
+```
+**Fix:** Removed duplicate line.
+**Status:** FIXED (commit f6feab9)
+
+### 2. FALSE POSITIVE: Python Property Definitions
+**Location:** `app_controller.py`, `gui_2.py`
+**Issue:** Audit script flagged `@property` getter/setter pairs as "duplicate definitions"
+**Explanation:** These are correct Python property patterns (getter + setter), not bugs
+**Status:** NOT AN ISSUE - False positive from audit script
+
+## Issues Identified (Not Fixed - Require Design Decisions)
+
+### 3. Duplicate Blocking/Unblocking Logic
+**Location:** `gui_2.py` vs `dag_engine.py`
+
+**gui_2.py has:**
+- `_cb_block_ticket()` - manual transitive blocking with while loop
+- `_cb_unblock_ticket()` - manual transitive unblocking with while loop
+- `_reorder_ticket()` - manual dependency validation
+
+**dag_engine.py has:**
+- `cascade_blocks()` - transitive blocking propagation
+- `topological_sort()` - dependency ordering
+
+**Issue:** Both do similar transitive closure operations on tickets, but on different data structures:
+- gui_2.py: `List[Dict[str, Any]]` (active_tickets)
+- dag_engine.py: `List[Ticket]` (Ticket objects from models.py)
+
+**Impact:** Potential state inconsistency if GUI state and DAG engine state diverge
+**Recommendation:** Refactor gui_2.py to call controller/engine methods rather than duplicating logic
+
+### 4. Two Parallel Ticket Representations
+**Locations:**
+- `app_controller.py`: `self.active_tickets: List[Dict[str, Any]]` (dictionaries)
+- `dag_engine.py`: `self.tickets: List[Ticket]` (dataclass instances)
+
+**Issue:** Ticket data is converted between dict and Ticket object forms. The `_load_active_tickets` method (line 3184) does:
+```python
+self.active_tickets = [asdict(t) if not isinstance(t, dict) else t for t in self.active_track.tickets]
+```
+
+**Recommendation:** Consider unifying to a single representation, or ensure clear ownership of state management.
+
+## Issues Not Addressed (Lower Priority)
+
+### 5. Widespread Mixed Indentation
+Many files contain 4-space indentation blocks within predominantly 1-space indented code. This is a style inconsistency but not a functional bug.
+
+### 6. Import Consolidation
+Multiple files have similar import patterns. Could benefit from a central `src/__init__.py` with commonly used imports, but this is cosmetic.
+
+## Summary
+- **Fixed:** 1 bug (duplicate line in rag_emb_provider setter)
+- **False Positives:** Property definitions flagged incorrectly by audit
+- **Design Issues:** 2 (duplicate blocking logic, parallel ticket representations)
+- **Cosmetic:** Mixed indentation, import patterns
