+# Widget + Field Refactor Sprint Agent Pack
+
+This folder contains the sprint-specific agent briefs for the widget-platform, field-management, and dashboard-query refactor.
+
+Source plan: `docs/refactor-sprint-plan.md`
+
+## Team
+
+- `O1-orchestrator.md`
+- `A1-architect.md`
+- `C1-field-domain-coder.md`
+- `C2-blueprint-ui-coder.md`
+- `C3-widget-platform-coder.md`
+- `C4-dashboard-data-coder.md`
+- `T1-test-agent.md`
+- `R1-reviewer.md`
+
+## Startup Order
+
+1. Start `O1`.
+2. Start `A1`.
+3. Wait for contract approval.
+4. Start `C1`, `C3`, and `T1`.
+5. Start `C2` after field contract is stable.
+6. Start `C4` once router/application boundaries are agreed.
+7. Keep `R1` reviewing every merge candidate.
+
+## Hard Rule
+
+The orchestrator never implements. `O1` may inspect, sequence, assign, review, and accept or reject work. `O1` must not patch files, write code, add tests, or fix lint/type issues directly.
+
+## Merge Order
+
+1. Shared contracts
+2. Shared/application helpers
+3. API integration
+4. UI integration
+5. Tests
+6. Final review
+
+## Shared Handoff Format
+
+Every agent handoff should include:
+
+- `summary`
+- `changed_files`
+- `acceptance_met`
+- `tests`
+- `open_risks`
+- `next_agent`
+
+## Shared Sprint Stories
+
+- `S1` Canonical field-definition contract
+- `S2` Shared dynamic-field validation and filter path
+- `S3` Typed widget config and layout versioning
+- `S4` Widget platform refactor
+- `S5` Dashboard query refactor groundwork
