HexStellar CLI — Proprietary Software License
Copyright © 2025-2026 Brayon Pieske. All rights reserved.

1. GRANT. Subject to a valid, active HexStellar subscription or license key,
   and to this Agreement, HexStellar ("Licensor") grants you a non-exclusive,
   non-transferable, revocable license to install and use the HexStellar
   command-line interface (the "Client") solely to submit your own problems to
   the HexStellar service and receive results, for your internal business or
   research purposes. The Client is a thin network client; all solving is
   performed by the HexStellar service, which is licensed separately under this
   Agreement and to which access is metered by your license key. Licensor
   ADDITIONALLY grants, without requiring a subscription, permission to install
   the Client and to use (a) the public evaluation sandbox and (b) any free tier
   made available upon registration, in each case subject to this Agreement and
   to the posted usage, rate, and size limits of that offering. This free grant
   is provided for evaluation and light use, may be changed, throttled, or
   withdrawn at any time, and does not waive any restriction in Section 2.

2. RESTRICTIONS. You may NOT, in whole or in part: (a) reverse engineer,
   decompile, disassemble, or otherwise attempt to derive the source code,
   algorithms, internal methods, or structure of the HexStellar service or
   engine, or probe, benchmark, or analyze the service to infer them;
   (b) copy, modify, translate, or create derivative works of the Client or the
   service; (c) rent, lease, lend, sell, sublicense, distribute, or make the
   Client or your service access available to any third party; (d) remove or
   alter any proprietary notice; (e) use confidential access, non-public
   artifacts, or observations obtained under NDA to build or materially assist
   a competing implementation; (f) publish a benchmark produced through
   prohibited security testing, reverse engineering, interference, limit
   evasion, or materially misleading measurement; or (g) circumvent any
   license, authentication, metering, rate-limit, or usage-limit mechanism.
   Truthful, reproducible benchmarks from ordinary authorized use are permitted
   when they comply with the posted Terms, preserve assurance and limitations,
   and do not imply endorsement.

3. OWNERSHIP. The Client and the service are licensed, not sold. All right,
   title, and interest in and to the Client, the HexStellar service and engine,
   and all related intellectual property remain the exclusive property of
   Licensor. The engine's methods are trade secrets; nothing in this Agreement
   transfers any ownership.

4. NO WARRANTY. THE CLIENT AND SERVICE ARE 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.

5. LIMITATION OF LIABILITY. IN NO EVENT SHALL LICENSOR BE LIABLE FOR ANY CLAIM,
   DAMAGES, OR OTHER LIABILITY, WHETHER IN CONTRACT, TORT, OR OTHERWISE, ARISING
   FROM, OUT OF, OR IN CONNECTION WITH THE CLIENT, THE SERVICE, OR THE USE OR
   OTHER DEALINGS IN THE CLIENT OR SERVICE.

6. TERMINATION. This license terminates automatically if you breach any term,
   or if your subscription or license key lapses. On termination you must stop
   using and delete all copies of the Client.

7. SERVICE TERMS AND ENTERPRISE. Use of the public sandbox, free tier, hosted
   Cortex service, and any automated agent integration is also governed by the
   then-current Terms at https://hexstellar.com/legal. Enterprise Low-Energy
   Runtime & Acceleration is not licensed by this Client license; customer
   deployment requires separately issued Enterprise terms and, where required,
   an NDA and order form.
