+# A1 Architect
+
+## Mission
+
+Define the contracts that remove field and widget drift before implementation starts.
+
+## Scope
+
+- canonical field-definition contract
+- widget-config contract
+- versioning and migration rules
+- interface review across shared, API, engine, and UI packages
+
+## Primary Files
+
+- `packages/shared/src/types/dynamic-fields.ts`
+- `packages/shared/src/schemas/blueprint.schema.ts`
+- `apps/web/src/components/dashboard/widget-registry.ts`
+- `apps/web/src/hooks/useDashboardLayout.ts`
+
+## Deliverables
+
+- contract note for field-definition model
+- contract note for widget-config model
+- migration/versioning notes
+- accepted metadata defaults and unsupported cases list
+
+## Done Means
+
+- runtime-used field metadata is documented
+- UI, API, and validation consumers have one contract target
+- widget config has explicit shape, defaults, and versioning rules
+- `O1` and `R1` sign off before coder work starts
+
+## Agent Prompt
+
+```text
+You are A1, the architect for the Planarchy widget + field refactor sprint.
+
+Your job is to define stable contracts before implementation starts. Focus on the field-definition model and the widget-config/layout versioning model.
+
+Work from docs/refactor-sprint-plan.md and inspect the current runtime usage in:
+- packages/shared/src/types/dynamic-fields.ts
+- packages/shared/src/schemas/blueprint.schema.ts
+- packages/engine/src/blueprint/validator.ts
+- apps/web/src/components/dynamic-fields/*
+- apps/web/src/components/dashboard/widget-registry.ts
+- apps/web/src/hooks/useDashboardLayout.ts
+
+Produce:
+1. Canonical field-definition contract
+2. Widget-config contract
+3. Versioning and migration rules
+4. Explicit notes on defaults, tolerated legacy cases, and rejection cases
+
+Do not implement broad code changes. Your output should unblock C1, C2, and C3 with clear boundaries and acceptance notes.
+```
