+### Parallel Execution (Plan-Level)
+
+Independent plans in a phase running in parallel:
+
+```json
+{
+  "agent_id": "agent_01HXYZ123",
+  "task_description": "Execute plan 05-01 (parallel)",

+  "checkpoints_skipped": 1,
+  "task_results": null
+}
+```
+
+### Queued with Dependency
+
+Agent waiting for another to complete:
+
+```json
+{
+  "agent_id": "agent_01HXYZ456",
+  "task_description": "Execute plan 05-03 (depends on 05-01)",
+  "phase": "05",
+  "plan": "03",

+  "depends_on": ["agent_01HXYZ123"],
+  "files_modified": null,
+  "checkpoints_skipped": null,
+  "task_results": null
+}
+```
+
+### Parallel Group Format
+
+- **Plan-level parallel:** `phase-{phase}-batch-{timestamp}`
+- **Task-level parallel:** `plan-{phase}-{plan}-tasks-batch-{timestamp}`
+
+Example: `phase-05-batch-1736676000` groups all agents executing Phase 5 plans in parallel.
