106dd4e63627c9adb984a795ea4086f3c53a6616 Mon Sep 17 00:00:00 2001 From: FireMonsterBlue Date: Sat, 3 Jan 2026 00:03:35 +0900 Subject: [PATCH 02/25] fix(mcp): Address code review feedback MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit High Priority Fixes: - Fix singleton race condition in ExchangeSessionManager and StrategySessionManager (moved initialization into __new__ with proper locking) - Add price validation (0-1 range) in create_order - Improve error handling in get_usdc_balance_polygon (no longer silently returns 0.0, now logs errors and returns None with warnings) - Add RPC endpoint fallbacks for better reliability Medium Priority Fixes: - Change strategy threads to daemon=True for clean shutdown - Make POLYGON_RPC_URL configurable via environment variable - Add fallback RPC endpoints for Polygon Code Quality: - Fix all ruff lint errors (import sorting, E402 noqa comments) - Add @pytest.mark.asyncio decorators to async tests - Fix test isolation issues with singleton cleanup 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- dr_manhattan/mcp/server.py | 16 +-

Fixed by: - Patch logger_module.setup_logger BEFORE importing dr_manhattan.utils - Recreate default_logger with patched function - Move third-party imports after patching 2. **Verbose mode stdout pollution**: DEFAULT_VERBOSE=True caused polymarket.py to print debug info (with checkmarks like ✓) to stdout.
