ARCHITECTURE DEEP-DIVE
From business capability to governed execution — every step, traceable.
Understand how Stackmint structures execution around durable contracts, not autonomous agents.

Atomic Execution Unit (Bud)
Contained Intelligence
LAYER 1
Business Capability
A stable, repeatable ability to produce a measurable business outcome. Owned by a business leader. Measured by KPIs. Independent of specific technologies or models. Capabilities survive architecture shifts, vendor changes, and AI evolution.
LAYER 2
Branch — The Execution Contract
The durable execution contract of a capability. Defines intended outcome, execution graph, allowed actions, data scope, policy constraints, approval gates, economic attribution, and audit guarantees.
LAYER 3
Bud Types
Connector Bud
Connects to external systems and APIs with declared schemas.
Logic Bud
Executes business rules and transformations.
Utility Bud
Handles formatting, validation, and data preparation.
Gate Bud (HITL)
Human-in-the-loop approval and review gates.
LAYER 4
Contained Intelligence
What AI CAN do
- Analyze data and generate structured outputs
- Recommend actions based on declared context
- Route decisions within declared scope
What AI CANNOT do
- Escalate permissions beyond declared scope
- Access undeclared data sources
- Perform undeclared side effects
- Bypass policy gates
GOVERNANCE
Capability Control Center
Governance command center for real-time oversight of all execution.
ARCHITECTURE PRINCIPLE
Governance by Construction
Security and compliance are not features bolted on after the fact. They are architectural properties.
