DataTug Commercial Subsystem

This directory contains the commercial subsystem, enterprise entitlement definitions, and proprietary extensions for the DataTug platform.

1. Governance & Licensing Scope

Unlike the community core (pkg/, cmd/, internal/, web/, docs/, scripts/, spec/), which is licensed under the Apache License 2.0, all code and documentation under commercial/ are governed by the DataTug Commercial Terms.

For full license terms, refer to:

• LICENSES/COMMERCIAL-TERMS.md
• LICENSING.md

2. Architectural Boundary & Separation of Concerns

DataTug enforces strict architectural boundaries to preserve the integrity of the open-source community edition:

1. No Inward Dependencies: Core community packages (pkg/, internal/, cmd/) must never import proprietary commercial implementations.
2. Contract-First Entitlement: The commercial/licensing package exposes clean Go interfaces (e.g., EntitlementVerifier, CapacityDescriptor, CoordinatorContract). This allows core subsystems to define optional hooks or runtime extension points without bundling proprietary enterprise logic into the open-source binaries.
3. Standalone / Community Operation: When running in community mode, DataTug operates fully standalone with built-in default/no-op verifiers, requiring zero proprietary runtime dependencies or network callouts to commercial license servers.

3. Package Summary

• commercial/licensing/: Defines enterprise entitlement contracts, capacity descriptors, license validation abstractions, and coordinator interfaces.
