Reframed from CC agent swarms to babysitter multi-harness parallel dispatch.\n\n## Current State\nctx.parallel.all() and ctx.parallel.map() provide one-shot parallel effect dispatch with deduplication. No persistent team identity across iterations, no inter-effect communication during execution, no fan-out/fan-in patterns with intermediate checkpoints.\n\n## Target State\nNamed effect groups with persistent identity across iterations. Multiple harnesses working concurrently on related tasks. Coordinator process pattern for ongoing management. Fan-out/fan-in delegation with intermediate checkpoints.\n\n## Dependencies\n- [GAP-PAR-001](../parallelization/GAP-PAR-001.md) -- concurrent execution\n- [GAP-PAR-002](../parallelization/GAP-PAR-002.md) -- async execution\n- [GAP-HADAPT-001](../harness-adaptation/GAP-HADAPT-001.md) -- capability-based routing\n\n## Key Files\n| Component | Path |\n|-----------|------|\n| Task batching | `packages/sdk/src/tasks/batching.ts` |\n| Harness adapters | `packages/sdk/src/harness/` |\n| Process context | `packages/sdk/src/runtime/processContext.ts` |\n\n## Recommendation\nPhase 3-4 implementation. Phase 3: named effect groups with persistent identity. Phase 4: inter-effect messaging via journal events and coordinator process pattern.\n",
