+  - Warning logging for degraded state with peer count thresholds
+  - Error logging for critical state detection
+- Implemented state validation logic with proper fallback behavior
+- Added connection statistics collection with peer health metrics
+
+**Session Management** (`crates/wraith-core/src/node/session.rs`)
+- Enhanced session documentation with detailed field descriptions
+- Added TODO tracking for incomplete health state enum matching
+- Improved connection statistics initialization
+
+#### Sprint 2: wraith-ffi Error Handling & Safety (TECH-DEBT-v1.5.0)
+

+- Improved error handling for file path validation
+- Enhanced documentation for progress tracking functions
+
+**Build Configuration** (`crates/wraith-ffi/build.rs`)
+- Added comprehensive documentation for cbindgen configuration
+- Improved header generation with detailed comments
+- Added platform-specific notes for library linking
+
+#### Sprint 3: wraith-cli & wraith-transfer Documentation (TECH-DEBT-v1.5.0)
+
+**CLI Configuration** (`crates/wraith-cli/src/config.rs`)
+- Enhanced configuration documentation with field descriptions
+- Added examples for configuration file format
+- Improved documentation for default values
+
+**CLI Main Module** (`crates/wraith-cli/src/main.rs`)
+- Added comprehensive command documentation
+- Enhanced error handling documentation
+- Improved help text for all CLI options
+
+**Tauri Commands** (`clients/wraith-transfer/src-tauri/src/commands.rs`)
+- Added detailed documentation for all 10 IPC commands
+- Enhanced parameter documentation with type information
+- Added return value documentation with error cases
+
+**Tauri Build** (`clients/wraith-transfer/src-tauri/build.rs`)
+- Added build script documentation
+
+#### Sprint 4: Clippy Pedantic Auto-Fixes (TECH-DEBT-v1.5.0)
+
+**Automated Code Quality Fixes**
+- Applied 104 auto-fixes for clippy pedantic warnings:
