+# machineGroupControl Function Anchor (Preparation Baseline)
+
+## 0) Connection Map (At a Glance)
+- Node type: machineGroupControl
+- Scope: baseline anchor scaffold to satisfy EVOLV required architecture.
+
+## 1) Unit Table (Initial Baseline)
+| Signal/Field | Represents | Default Unit | Source of Truth | Produced By | Consumed By | Fallback/Degraded Behavior |
+|---|---|---|---|---|---|---|
+| TBD | TBD | TBD | nodes/machineGroupControl/src/* | TBD | TBD | TBD |
+
+## 2) Class Identity
+- Runtime registration: nodes/machineGroupControl
+- Node-RED wrapper: nodes/machineGroupControl/src/nodeClass.js (when present)
+- Domain logic: nodes/machineGroupControl/src/specificClass.js (when present)
+- Editor UI: nodes/machineGroupControl/*.html (when present)
+
+## 3) Current Gaps To Resolve Before Declaring Anchor Complete
+- Replace placeholder sections with full contract mapping on first functional change.
+
+## 4) Standardization Plan
+1. Maintain this anchor and evidence docs with behavior changes.
+2. Maintain tests under test/basic, test/integration, test/edge.
+3. Maintain examples package (README, basic.flow.json, integration.flow.json, edge.flow.json).
+
+## 5) Acceptance Criteria For Completion
+- Anchor/evidence artifacts exist.
+- Test structure exists.
+- Example structure exists.
