1.2 "Project Sandstar" means the open-source control engine that merges the Sedona Framework with Project Haystack, as maintained at the official Project Sandstar repositories, including the Sandstar C/C++ engine, the eacio Sedona kit, device templates, and Zinc grid configurations.

1.3 "Sedona Framework" means the open-source software environment for building smart, networked, embedded devices, including the Sedona Virtual Machine (SVM), the Sox protocol, Sedona component model, and associated kits, as maintained by the Sedona Alliance or its successors.

1.4 "Project Haystack" means the open-source semantic data modeling standard for IoT data, including Haystack tag definitions, Zinc data format, filter syntax, and the Haystack REST API (Ops), as maintained by Project Haystack or its successors.

1.7 "Qualifying Use" means use of the Licensed Software in which the Licensed Software exclusively consumes, displays, interacts with, and operates upon Sandstar-Origin Data. A deployment constitutes Qualifying Use when every data packet rendered, visualized, browsed, edited, or acted upon by the Licensed Software can be traced back to a Project Sandstar hardware-agnostic controller running Sedona and Haystack.

1.9 "You" / "Licensee" means the individual or legal entity exercising rights under this license.

1.10 "Licensor" means Anka Labs, Inc., or its authorized successors and assigns.

Subject to the terms of this license, the Licensor grants You a worldwide, non-exclusive, royalty-free, non-transferable right to:

(a) Use the Licensed Software for any purpose, including commercial purposes, provided the Licensed Software exclusively consumes Sandstar-Origin Data (Qualifying Use).

(b) Study the source code of the Licensed Software, inspect its operation, and learn from its design.

(c) Modify the Licensed Software and create derivative works for use within Qualifying Use deployments.

(e) Deploy the Licensed Software on an unlimited number of devices and servers within a Qualifying Use deployment at no charge.

3.1 Any use of the Licensed Software that does NOT meet the definition of Qualifying Use (Section 1.7) requires a separate commercial license from Anka Labs, Inc.

3.3 No Unified View Without Full Sandstar Ecosystem. The Licensed Software may not be used as a single-pane-of-glass interface that unifies data from both Sandstar and non-Sandstar systems without a commercial license.

3.4 For clarity, the following scenarios require a commercial license: consuming data from BACnet, Modbus, LonWorks, KNX, or other legacy protocols in the Licensed Software; operating the Licensed Software as a unified dashboard combining Sandstar-Origin Data with Non-Sandstar Data; proxying Non-Sandstar Data through a Haystack server and then consuming it in the Licensed Software; and any deployment in which the Licensed Software does not exclusively consume Sandstar-Origin Data.

3.5 To obtain a commercial license, contact: Anka Labs, Inc. — 6800 West Gate Blvd, Suite 132-577, Austin, TX 78745, USA — Email: [email protected] — Phone: +1 (512) 540-3010

3.6 Commercial license terms, including pricing, deployment scope, support, and SLA provisions, are negotiated separately and are not governed by this document.

4.2 Licensees shall not circumvent, disable, modify, or bypass any data origin verification mechanism implemented in the Licensed Software or the Project Sandstar engine. Circumvention of such mechanisms constitutes a material breach of this license.

4.3 In the absence of technical verification mechanisms, Licensees are responsible for ensuring that their deployment meets Qualifying Use conditions through architectural controls, configuration, and operational procedures.

5.1 Licensees operating under Qualifying Use may freely modify, extend, enhance, and customize the Licensed Software without restriction on the nature of their modifications, provided the resulting deployment continues to meet Qualifying Use conditions.

5.2 There is no obligation to contribute modifications back to the Licensor or to the Project Sandstar community. Contributions are welcome but voluntary.

5.3 If a modification causes the Licensed Software to consume Non-Sandstar Data, the deployment immediately becomes Non-Qualifying Use and is subject to the Commercial License Requirement (Section 3).

5.4 Modifications must not remove, alter, or obscure this license, any copyright notices, or any attribution to the Licensor.

6.1 This license does NOT include any provision for automatic conversion to a permissive open-source license (such as MIT, Apache 2.0, or similar) after any period of time.

6.2 The Qualifying Use condition applies permanently to every version of the Licensed Software released under this license, without exception.

6.3 The Licensor reserves the right to release future versions under different license terms at its sole discretion, but such changes will not retroactively alter the terms of previously released versions.

7.2 You may not use the names "Anka Labs," "Project Sandstar," "Mobilytik," "Visualytik," "Ankalytik," or related trademarks to endorse or promote derivative works without prior written permission from the Licensor.

8.1 The Licensor retains all right, title, and interest in and to the Licensed Software, including all intellectual property rights.

8.2 This license does not grant any rights to patents, trademarks, trade secrets, or other intellectual property of the Licensor except the limited rights expressly stated herein.

8.3 If You create modifications or derivative works, You own the intellectual property in Your original contributions, but the underlying Licensed Software remains the property of the Licensor.

9.1 Self-Assessment. Licensees are responsible for determining whether their deployment constitutes Qualifying Use or requires a commercial license.

9.2 Audit Right. The Licensor reserves the right, upon reasonable notice, to verify that deployments using the Licensed Software comply with the terms of this license.

9.4 Failure to cure within the 60-day period constitutes copyright infringement and the Licensor may pursue all remedies available under applicable law.

THE LICENSED SOFTWARE IS PROVIDED "AS IS," WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NONINFRINGEMENT.

IN NO EVENT SHALL THE LICENSOR'S TOTAL LIABILITY UNDER THIS LICENSE EXCEED THE AMOUNT OF LICENSE FEES ACTUALLY PAID BY THE LICENSEE TO THE LICENSOR IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM. FOR QUALIFYING USE DEPLOYMENTS WHERE NO FEES HAVE BEEN PAID, THE LICENSOR'S LIABILITY SHALL NOT EXCEED ZERO DOLLARS ($0).

12.1 This license is effective until terminated.

12.2 Your rights under this license terminate automatically if You fail to comply with any of its terms and do not cure the non-compliance within the period specified in Section 9.3.
