Brummer MCP Server

# Master Request Analysis - Lock-Free Architecture **Original Request**: Complete analysis of script, log, and error tools for race conditions and create a plan to reduce locking using channels and goroutines **Business Context**: Developer experiencing lockups with `scripts_status` MCP tool, needs more robust debugging application **Success Definition**: Simpler, more maintainable code with fewer lockup risks, even if performance is lower **Project Phase**: Refactoring/Architecture Improvement **Timeline Constraints**: None specified - focus on correctness over speed **Integration Scope**: MCP tools, Process Manager, Log Store, Proxy Server, TUI components ## Critical Assumptions Identification **Technical Assumptions**: - Channels provide simpler coordination than mutexes for low-volume debugging workload ✓ - Single goroutine per subsystem is sufficient for coordination ✓ - Integration tests can be added incrementally as refactoring progresses ✓ **Business Assumptions**: - Performance can be sacrificed for simplicity and maintainability ✓ - Users value reliability over speed for debugging tools ✓ - Features can be temporarily removed and re-added later ✓ **Architecture Assumptions**: - Current event bus can handle channel-based architecture ✓ - Internal APIs can be freely modified for simplicity ✓ - Debug/inspection tooling can be built alongside refactoring ✓ **Resource Assumptions**: - Time available for careful, incremental refactoring ✓ - No pressure for immediate performance gains ✓ - Developer time for building test infrastructure ✓ **Integration Assumptions**: - MCP tools can be refactored one at a time ✓ - TUI can adapt to new event-driven updates ✓ - Existing tests won't block API changes ✓ ## Assumption Risk Assessment **High-Risk Assumptions**: None - focusing on simplicity reduces architectural risks **Medium-Risk Assumptions**: Integration test coverage may reveal hidden dependencies **Low-Risk Assumptions**: All other assumptions validated by simplicity-first approach
