  "summary": "Successfully added comprehensive unit tests for critical uncovered areas across kb packages:\n\n1. **packages/core/src/board.test.ts** (24 tests) - Tests for column transition logic (`canTransition`, `getValidTransitions`) and dependency resolution (`resolveDependencyOrder`) including linear dependencies, diamond dependencies, disconnected components, and circular dependency handling.\n\n2. **packages/engine/src/agent-heartbeat.test.ts** (32 tests) - Tests for the `HeartbeatMonitor` class covering constructor options, start/stop lifecycle, agent tracking, heartbeat recording, health checking, missed heartbeat detection with callback triggers, and unresponsive agent termination.\n\n3. **packages/dashboard/app/utils/modelFilter.test.ts** (21 tests) - Tests for the `filterModels` utility function including empty/whitespace filters, case-insensitive matching, provider/ID/name filtering, multi-word AND logic, and substring matching.\n\n4. **packages/dashboard/app/hooks/useToast.test.tsx** (18 tests + 1 skipped) - Tests for the `useToast` React hook covering provider rendering, error handling outside provider, toast addition with various types, auto-assigned sequential IDs, auto-removal after 4000ms, manual removal, and multiple simultaneous toasts.\n\nAll tests pass, TypeScript type checking passes for core and engine packages, and build succeeds.",
