This source code is published for transparency, auditability, and personal reading. It is NOT open-source software as defined by the Open Source Initiative (https://opensource.org/osd). No rights are granted under this document except those narrowly enumerated below. 1. PERMITTED USES Subject to full and ongoing compliance with every term of this license, and only so long as you do not engage in any Prohibited Use (Section 2), the following are permitted without additional permission: (a) Viewing and reading the source code in this repository. (b) Downloading and installing official pre-built binary releases of MUX0 published by the copyright holder and running them on hardware you own, lease, or otherwise control — including: (i) personal use; (ii) use inside any organization (including for-profit companies), by employees or contractors, on that organization's devices or on personal devices used for that organization's work; (iii) use of MUX0 as a tool to design, build, test, debug, deploy, operate, or support other software, services, or content — including commercial, revenue-generating, or client-facing work. Nothing produced inside MUX0 (code, documents, command output, transcripts, etc.) is subject to this license; you own whatever you create with it. (c) Compiling the source code locally, on a machine you own or control, solely for your own or your organization's internal use as described in (b), provided the resulting binary is not redistributed, published, hosted as a service, bundled into any product, or otherwise made accessible to anyone outside your organization. (d) Creating a personal fork of this repository on a public code-hosting platform (e.g., GitHub), preparing modifications to the source code on that fork, and proposing those modifications back to the copyright holder via pull request or equivalent contribution channel. Contributions so submitted are governed by Section 9 (Contributions). A fork made under this subsection: (i) must not be promoted, marketed, or distributed as an alternative, replacement, or competing version of MUX0; (ii) must not be used to publish or distribute compiled binaries to anyone other than the fork owner; (iii) must retain a clear reference to this upstream repository and its LICENSE file, unmodified; (iv) must not be renamed or rebranded in a way that would confuse users about its relationship to MUX0. A fork kept up for ongoing contribution is fine; a fork kept up as a parallel distribution is not. In short: using MUX0 as a terminal to do your work — personal or commercial — is fine. Forking to contribute back is fine. What is not fine is redistributing, repackaging, reselling, or maintaining a competing distribution of MUX0 itself. See Section 2. 2. PROHIBITED USES Except with the prior, specific, written permission of the copyright holder, you MAY NOT: (a) Copy, reproduce, mirror, or republish the source code, in whole or in part, in any form or medium, whether verbatim or modified, except as expressly permitted by Section 1(d) (forks for contribution). (b) Maintain any fork, mirror, or derivative repository for purposes other than proposing contributions back to the upstream project — including, without limitation, maintaining a long-running divergent fork, a competing distribution, a rebrand, or a hard-fork project. (c) Create, prepare, distribute, sublicense, or publish any derivative work, adaptation, port, translation, or modification of the source code or binaries to any third party, whether free of charge or for a fee. (Preparing modifications on a personal contribution fork for the purpose of submitting a pull request is permitted under Section 1(d) and is not considered distribution.) (d) Redistribute MUX0 itself (source or binary) to third parties in any form — including, without limitation: (i) reselling, sublicensing, renting, leasing, or lending MUX0; (ii) bundling MUX0 into a product, service, device, or distribution that you ship, sell, license, or otherwise make available to third parties; (iii) hosting MUX0 (or any service whose primary value derives from MUX0) as a Software-as-a-Service or other managed offering available to users outside your organization; (iv) publishing compiled builds of MUX0 on any third-party distribution channel (app store, package manager, website, mirror, etc.) other than the copyright holder's own official channels. This clause is the reason this license exists: MUX0 is free to *use* commercially, but not free to *redistribute* or *productize*. (e) Remove, alter, or obscure any copyright, trademark, author, attribution, or proprietary notice contained in the source code or binaries. (f) Use the name "MUX0", the MUX0 logo, or any confusingly similar name or mark to identify, promote, or market any product, service, fork, or derivative work. (g) Train, fine-tune, evaluate, benchmark, or condition any machine-learning model, dataset, or AI system on the source code (in whole or in part), or publish any dataset derived from the source code for such purposes, without prior written permission. 3. NO TRANSFER OF OWNERSHIP All right, title, and interest in and to the source code and binaries, including all intellectual property rights, remain exclusively with the copyright holder. Nothing in this license transfers or assigns any ownership interest to you. 4. THIRD-PARTY COMPONENTS This project depends on third-party libraries (including, without limitation, ghostty and Sparkle), each of which is distributed under its own respective license. Those components remain governed by their original licenses, which are not superseded by this document. 5. TERMINATION Any breach of Section 1 or Section 2 automatically and immediately terminates all rights granted to you under this license, without notice. Upon termination you must cease all use of the source code and binaries, delete all local copies, and destroy any materials derived from them. 6. NO WARRANTY THE SOURCE CODE AND BINARIES 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, TITLE, AND NON-INFRINGEMENT. 7. LIMITATION OF LIABILITY IN NO EVENT SHALL THE COPYRIGHT HOLDER BE LIABLE FOR ANY CLAIM, DAMAGES, OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, TORT, OR OTHERWISE, ARISING FROM, OUT OF, OR IN CONNECTION WITH THE SOURCE CODE OR BINARIES OR THE USE OR OTHER DEALINGS IN THEM. 8. GOVERNING LAW This license is governed by the laws of the jurisdiction of the copyright holder's primary residence, without regard to its conflict of law provisions. 9. CONTRIBUTIONS By submitting any contribution (pull request, patch, issue comment containing code, or equivalent) to this project, you: (a) Represent that the contribution is your original work, or that you otherwise have the right to submit it under the terms of this license; (b) Irrevocably grant the copyright holder a perpetual, worldwide, royalty-free, non-exclusive license to use, reproduce, modify, relicense, sublicense, and distribute your contribution as part of MUX0 under this license or any future license the copyright holder chooses to adopt for MUX0; (c) Understand that your contribution, once merged, is subject to the same terms as the rest of MUX0 — in particular, you do not retain the right to redistribute a version of MUX0 containing your contribution outside the terms of this license. For inquiries about redistribution, bundling, hosting as a service, maintaining a non-contribution fork, or any other use not permitted above, contact the copyright holder.
