DataTug Commercial Engine

This directory contains commercial extensions and enterprise entitlement mechanisms for DataTug.

Governance & Boundary

The code in this directory (commercial/) is proprietary and governed by the DataTug Commercial Terms (see LICENSES/COMMERCIAL-TERMS.md).

Unlike the permissive open-source Community components (apps/, pkg/, internal/, root CLI main.go) licensed under Apache License 2.0, the commercial engine provides centralized coordination, multi-user sharing, enterprise audit logging, and team runners for organizational self-hosted environments.

Features Gated by Commercial Licensing

• central_watch_coordinator: Shared centralized watch coordinator scheduling jobs across organizational runners.
• shared_execution_store: Centralized multi-user execution store and historical query persistence.
• team_audit_trail: Immutable organizational activity logging and compliance auditing.
• sms_notifications: Cellular SMS alerting via cloud telephony providers (e.g., Twilio).

Architectural Principles

1. Air-Gapped & Offline: License verification performs local cryptographic verification of Ed25519 digital signatures. No network phone-home, external validation APIs, or cloud beacons are required.
2. Operational Grace Period: A 14-day grace period ensures that accidental expiration of a license does not instantly disrupt active workflows. Operators receive actionable warnings on stderr.
3. Fails-Open for Developers: Single-user local CLI, TUI, and local datatug serve on localhost remain part of the Community edition and never require a commercial license.
