+
+    ;;; ==================================================
+    ;;; KNOWN ISSUES
+    ;;; ==================================================
+    ;;;
+    ;;; COMPILER WARNINGS (34 total, all non-critical):
+    ;;;   - 18 unused imports/variables (Color, Watcher, HashMap, etc.)
+    ;;;   - 3 dead code functions (hash_string, hash_file, calculate_depth)
+    ;;;   - 1 mutable variable not needed (cache_write in executor)
+    ;;;
+    ;;; POTENTIAL SECURITY CONCERNS:
+    ;;;   - Shell executor trusts shell escaping - needs review
+    ;;;   - No input sanitization for shell commands
+    ;;;
+    ;;; TECHNICAL DEBT:
+    ;;;   - 69 .unwrap() calls in library code - verify none panic
+    ;;;   - Some synchronous file I/O in async context
+    ;;;   - No benchmark suite for regression tracking
+    ;;;
+    ;;; ==================================================
+
+    ;;; ==================================================
+    ;;; QUESTIONS FOR REVIEW
+    ;;; ==================================================
+    ;;;
+    ;;; 1. Should dead code functions (hash_string, hash_file) be kept
+    ;;;    for future use or removed to reduce warnings?
+    ;;;
+    ;;; 2. What is the security model for shell command execution?
+    ;;;    Should we sandbox or restrict shell access?
+    ;;;
+    ;;; 3. Is parallel execution needed for MVP or acceptable as post-MVP?
+    ;;;
+    ;;; 4. Should we add timeout configuration to pipeline stages?
+    ;;;
+    ;;; 5. What's the target RSR compliance level for conflow itself?
+    ;;;    (Currently aiming for Silver)
