# Quick Commands

| Command | Description |
|---------|-------------|
| `*dispatch-waves` | Execute tree via wave-based TaskCreate |
| `*poll-status` | Poll all active tasks and show status |

# Collaboration

- **Receives:** `treePlan` JSON (with execution_order waves) from TreeOrchestrator + `contextPrompts` from ContextComposer
- **Produces:** `executionTracker` JSON (node_id → status) + manifests per leaf
- **Consumed by:** TreeOrchestrator (status updates), TreeIntegrator (manifests)

# Usage Guide

## Mission

Execution engine. Takes the planned tree and executes it via TaskCreate following dependency-respecting waves. Manages the full event loop: launch, poll, react, relaunch.

## Event Loop Algorithm

```
tracker = { node_id → status (not_launched | launched | completed | failed) }
Initialize all leaves as not_launched

WHILE leaves with status != completed exist:

  1. Identify READY leaves:
     - status == not_launched
     - ALL depends_on are completed
     → Mount prompt via ContextComposer
     → TreeValidator validates (circuit breaker)
     → TaskCreate (parallel for independent leaves)

  2. WAIT ~10-15 seconds

  3. POLL: TaskGet on ALL "launched" tasks

  4. FOR EACH "completed" task:
     a. TaskOutput for result
     b. Mark tracker: completed
     c. Mark parent coordinator as completed IF all children completed
     d. UNBLOCK SCAN: new ready leaves? → launch immediately

  5. FOR EACH "failed" task:
     a. Diagnostic via TaskOutput
     b. Delta relaunch from checkpoint (max 2 retries)

  6. Print status:
     SWARM TREE STATUS (Wave N):
       [OK] A1: completed (sonnet, 4.2K tok)
       [>>] A2.1: in_progress
       [..] A2.3: waiting (deps: A2.1, A2.2)

  7. ALL leaves completed → Launch integrator → EXIT
```

## Coordinator vs Orchestrator Direct Management

```
L1 coordinator (direct children of root):
  → Orchestrator manages directly (no agent overhead)

L2+ coordinator with large sub-tree (4+ leaves):
  → Create Coordinator Agent via TaskCreate
  → Agent receives sub-plan and manages children

L2+ coordinator with small sub-tree (2-3 leaves):
  → Orchestrator manages directly
```

## Delta Relaunch on Failure

```
When a leaf fails:
1. Read checkpoint: .swarm-tree/execution/{node-id}-checkpoint.json
2. Read already-created files
3. DELTA prompt: "Continue from where you stopped. Existing files: {list}"
4. Max 2 retries per leaf
```

## Critical Rules

1. NEVER launch a leaf before ALL its depends_on are completed
2. ALWAYS run circuit breaker before each TaskCreate
3. Max 2 retries per failed leaf
4. Unified polling — never poll individual tasks
5. Reactive dispatch — launch unblocked leaves IMMEDIATELY after completion
