+# Task 7: WebSocket Signaling Server - Issues Encountered
+
+## Build System Issues
+- `libspa-sys` build script failed when running full cargo test due to missing PipeWire dev dependencies
+- Solution: Used `cargo test --no-default-features` to skip PipeWire feature during testing
+
+## Compilation Errors
+
+### E0433: Unresolved Module `tungstenite`
+- **Error**: Could not resolve `tungstenite::Error` type
+- **Cause**: Import statement only imported specific items, not the full module
+- **Solution**: Added `Error as WsError` to tokio_tungstenite imports
+- **Pattern**: Use type aliasing for frequently used imported types
+
+### E0599: No Method `next`
+- **Error**: `WebSocketStream` didn't have `next()` method in scope
+- **Cause**: Missing `StreamExt` trait from futures crate
+- **Solution**: Added `use futures::StreamExt` to imports
+- **Lesson**: WebSocketStream implements Sink and Stream traits from futures, both needed
+
+### E0282: Type Annotations Needed
+- **Error**: Compiler couldn't infer error types in closures
+- **Affected locations**: `handle_client` message variable, multiple error closures
+- **Solution**: Added explicit type annotations: `let msg: Message`, `|e: WsError|`
+- **Pattern**: Async WebSocket code frequently requires explicit type annotations
+
+### Missing Error Variant
+- **Error**: Used `SignalingError::SessionNotFound` which doesn't exist
+- **Root Cause**: Error exists in `WebRtcError` enum, not `SignalingError`
+- **Solution**: Changed to `SignalingError::ProtocolError` with descriptive format string
+- **Alternative**: Could add `SessionNotFound` variant to `SignalingError` enum
+
+## Code Organization Issues
+
+### Duplicate Struct Definition
+- **Issue**: Initially had both placeholder and complete `SignalingServer` struct definitions
+- **Cause**: Added new struct without removing old placeholder
+- **Detection**: Compiler reported "unclosed delimiter" error
+- **Solution**: Removed old placeholder struct definition
+- **Prevention**: Always review file for duplicates before major edits
+
+## Testing Considerations
+
+### Port Conflicts
+- **Issue**: Default port 8765 might conflict during concurrent test runs
+- **Solution**: Used ephemeral ports (18765+) for test instances
+- **Pattern**: Add test port offset (10000+) to default ports
+
+### Dependency Testing
+- **Issue**: Full build requires PipeWire system libraries
+- **Solution**: Test with `--no-default-features` to test core functionality
+- **Trade-off**: Can't test integration with features disabled
