- Define Message interface (request/response/event/error) - Define Task interface with priority and retry logic - Define Agent, ContextManager, and Coordinator interfaces - Add Logger interface for structured logging - Establish message-driven architecture foundation - Install @types/node dependency Foundation for Central Nervous System architecture. Ticket: #7
SubagentCoordinator (442 lines): - Central nervous system orchestrator - Agent registration and lifecycle management - Message routing (one-to-one and broadcast) - Task execution with concurrency control - System statistics and health monitoring ContextManager (127 lines): - Hippocampus for shared state management - Repository indexer access - Message history (configurable max size) - Key-value state storage - Context statistics TaskQueue (232 lines): - Motor cortex for task execution - Priority-based scheduling (0-10) - Concurrency control (max concurrent tasks) - Retry logic with configurable max retries - Task lifecycle (pending → running → completed/failed) - Automatic cleanup of old tasks CoordinatorLogger (82 lines): - Structured logging with context - Log levels (debug/info/warn/error) - Child loggers with inherited context - Timestamp formatting - Future: extractable to @lytics/croak Architecture: - Self-contained folder structure - Message-driven communication - Graceful error handling - Shared context pattern Ticket: #7
ContextManager Tests (17 tests): - Indexer management and access control - State management (get/set/delete/clear/keys) - Message history with size limits - Statistics reporting - 100% statement coverage, 100% branch coverage TaskQueue Tests (24 tests): - Task enqueueing and priority sorting - Task status management (pending/running/completed/failed) - Retry logic with max retries - Concurrency control and limits - Task cancellation - Cleanup of old tasks - Error handling - 97% statement coverage, 89% branch coverage Test Coverage Summary: - 41 tests passing - Context Manager: 100% statements, 100% branches - Task Queue: 97% statements, 89% branches - Logger: 89% statements, 93% branches (tests in prev commit) All tests use Vitest with proper mocking and isolation. Ticket: #7
