- Add RemoteNodeClient and RemoteNodeRuntime with comprehensive lifecycle, status, and metrics test coverage
- Route projects by node assignment in ProjectManager and integrate remote runtime handling in HybridExecutor
- Introduce NodeHealthMonitor and wire diagnostic logging/export updates for remote node health tracking
- Harden remote runtime shutdown checks and type-safety paths surfaced during review feedback
- Add HeartbeatTriggerScheduler class with timer, assignment, and on-demand trigger types
- Wire timer-based periodic wakeups using per-agent heartbeatIntervalMs config
- Add agent:assigned event in AgentStore for assignment-triggered wakeups
- Enhance POST /api/agents/:id/runs with WakeContext and 409 conflict on concurrent runs
- Integrate trigger scheduler into InProcessRuntime lifecycle (start/stop)
- Add enabled field to AgentHeartbeatConfig for per-agent trigger control
- Update AGENTS.md with heartbeat trigger scheduling documentation
- Extract shared agent tools (bash, read, write, edit) from executor into agent-tools.ts for reuse
- Implement heartbeat execution in HeartbeatMonitor with configurable interval and task_done support
- Wire heartbeat execution into InProcessRuntime lifecycle (start/stop)
- Add comprehensive test suite covering execution, timeouts, concurrency, and error handling
- Add heartbeat-related log constants to logger
- Add getFusionDir() method to TaskStore for resolving agent database path
- Update in-process-runtime to use getFusionDir() instead of hardcoded path
- Update dashboard routes AgentStore initialization to use getFusionDir()
- Add changeset for published package patch bump
- Add mission CLI commands and pi extension tools for creating missions, milestones, slices, features, and task links
- Extend core mission storage and schema migrations with auto-advance support, task slice linkage, and comment normalization coverage
- Wire mission-aware scheduler and executor behavior so linked features progress with task execution and completed slices can auto-activate follow-on work
- Add regression tests for mission CLI parsing, extension behaviors, scheduler mission semantics, and executor integration
- Define ProjectRuntime interface with unified task execution contract\n- Implement IPC protocol for host-worker communication (messages, streaming, heartbeats)\n- Add InProcessRuntime for synchronous in-process task execution\n- Add ChildProcessRuntime with isolated worker processes for sandboxed execution\n- Implement ProjectManager to coordinate runtime selection and task lifecycle\n- Update engine exports to expose runtime APIs\n- Add comprehensive tests for all runtime implementations and IPC protocol
