+# Web3AI ↔ Tower Control Integration
+
+This document explains how `Web3AI` should integrate with `lippytm-lippytm.ai-tower-control-ai`.
+
+The purpose is to keep commerce logic modular while allowing the control layer to observe, route, and coordinate monetized workflows.
+
+---
+
+## Integration Goal
+
+Allow the Control Tower to:
+
+- observe payment and service events
+- trigger monetized workflow paths
+- coordinate enterprise or premium operations
+- keep commerce state visible without tightly coupling business logic
+
+---
+
+## Separation of Responsibility
+
+### Web3AI owns
+- payment routes
+- subscription logic
+- access state
+- service receipts
+- commerce product definitions
+
+### Tower Control owns
+- orchestration
+- mission execution
+- fleet visibility
+- rollout governance
+- event aggregation
+
+This preserves clean lane boundaries.
+
+---
+
+## Suggested Event Flow
+
+1. checkout created in Web3AI
+2. Web3AI emits commerce event
+3. Control Tower records or reacts to event
+4. if payment or service activation succeeds, Control Tower may trigger downstream workflows
+5. service completion may update service receipt state
+
+---
+
+## Suggested Shared Events
+
+- `billing.event`
+- `task.created`
+- `task.completed`
+- `deployment.completed`
+- `content.generated`
+
+---
+
+## Best Practices
+
+- keep sensitive payment logic inside Web3AI
+- expose only the event surfaces needed by the control layer
+- use service receipts as proof, not as the only source of operational truth
+- do not let orchestration logic directly rewrite commerce records without policy checks
+
+---
+
+## Rule of thumb
+
+Commerce should be connectable to orchestration, but not swallowed by it. Keep billing modular, observable, and policy-aware.
