+# C2 Blueprint UI Coder
+
+## Mission
+
+Align blueprint and dynamic-field UI to the canonical field contract so UI behavior stops drifting from schema behavior.
+
+## Scope
+
+- blueprint field editor
+- dynamic-field editor
+- dynamic-field renderer
+- custom field filter bar
+
+## Primary Files
+
+- `apps/web/src/components/blueprints/BlueprintFieldEditor.tsx`
+- `apps/web/src/components/dynamic-fields/DynamicFieldEditor.tsx`
+- `apps/web/src/components/dynamic-fields/DynamicFieldRenderer.tsx`
+- `apps/web/src/components/ui/CustomFieldFilterBar.tsx`
+
+## Deliverables
+
+- UI aligned to shared field metadata
+- removed implicit assumptions in rendering and filtering
+- safer handling of unsupported or legacy field metadata
+
+## Done Means
+
+- UI uses the canonical metadata model from `A1`
+- editor, renderer, and filter bar do not rely on undeclared properties
+- field-specific defaults and edge cases behave consistently with validation
+
+## Agent Prompt
+
+```text
+You are C2, the blueprint UI coder for the Planarchy refactor sprint.
+
+Update the blueprint field editor and dynamic-field UI to use the canonical field-definition contract. Remove UI-only assumptions and align rendering and filtering behavior with the shared schema.
+
+Work in:
+- apps/web/src/components/blueprints/BlueprintFieldEditor.tsx
+- apps/web/src/components/dynamic-fields/DynamicFieldEditor.tsx
+- apps/web/src/components/dynamic-fields/DynamicFieldRenderer.tsx
+- apps/web/src/components/ui/CustomFieldFilterBar.tsx
+
+Requirements:
+1. Consume only declared field metadata.
+2. Keep required/optional/select/multi-select behavior aligned with validation.
+3. Degrade safely on unsupported or stale metadata.
+4. Coordinate with T1 for regression coverage on visible behavior.
+
+Your handoff must list any remaining UI edge cases that depend on legacy data.
