# Commercial license

This project is **dual-licensed**: [GNU AGPL-3.0](LICENSE) is the default track, and the commercial track described here is an alternative to it. The two are **parallel choices** — buying the commercial track is not a requirement imposed on anyone using the AGPL track.

## Which track applies

| Your use | Track |
|---|---|
| Personal use, study, research, evaluation | 1 — AGPL-3.0 |
| Internal deployment of an unmodified build | 1 — AGPL-3.0 |
| Modified build, deployed or distributed with its source disclosed | 1 — AGPL-3.0 |
| Closed-source hosted service offered to others | 2 — commercial |
| Embedded in a proprietary product that you ship | 2 — commercial |

Commercial use itself is allowed under **both** tracks. What distinguishes them is the source-disclosure obligation: AGPL-3.0 §13 requires that users of your modified build — including users of a network service — receive the corresponding source.

## What the commercial track provides

- The same rights AGPL-3.0 grants you, **without** the §13 source-disclosure obligation.
- Scope, term, deployment model and fee are set in the agreement both sides sign. **This document is an invitation to negotiate; it is not itself a license grant.**

## How to obtain one

Write to **maogeigei@gmail.com** stating the intended use, the deployment model and the expected scale.

## Third-party components

Upstream DeepSeek Harness is licensed under the MIT License. This project does **not** include or distribute it — it is invoked at runtime as a separate process — so its terms are unaffected by either track above.
