-# Fanout Contributor License Agreement
+# LabStack Contributor License Agreement
 
-Thank you for contributing to Fanout. This agreement clarifies the intellectual
-property license granted with contributions from any person or entity, and
-protects both you and LabStack LLC ("LabStack").
+Thank you for your interest in contributing to a project of LabStack LLC
+("LabStack", "we", "us"), such as Driga, Fanout, or Onebox.
 
-By signing, you accept and agree to the following terms for your present and
-future contributions to Fanout. Except for the licenses granted here, you retain
-all right, title, and interest in and to your contributions.
+This Contributor License Agreement ("Agreement") documents the rights granted
+by contributors to LabStack. It applies to any Contribution you submit to any
+project owned or managed by LabStack. Signing it is a one-time step; it covers
+all of your future Contributions to LabStack projects unless you notify us
+otherwise.
+
+**You keep the copyright in your Contribution.** This Agreement is a license,
+not an assignment. You may continue to use your Contribution however you wish,
+including in other projects under other licenses.
 
 ## 1. Definitions
 
-**"You"** means the copyright owner, or the legal entity authorized by the
-copyright owner, entering into this agreement with LabStack.
+**"You"** means the individual who submits a Contribution to LabStack, or the
+legal entity on whose behalf a Contribution is submitted. For a legal entity,
+the entity making a Contribution and all other entities that control, are
+controlled by, or are under common control with that entity are considered a
+single Contributor.
 
 **"Contribution"** means any original work of authorship, including any
-modification to or addition to an existing work, that is intentionally submitted
-by You to LabStack for inclusion in Fanout. "Submitted" means any form of
+modification to or addition to an existing work, that is intentionally
+submitted by You to LabStack for inclusion in, or documentation of, any of the
+products owned or managed by LabStack. "Submitted" means any form of
 electronic, verbal, or written communication sent to LabStack or its
-representatives, including but not limited to pull requests, issues, and
-electronic mailing lists.
-
-## 2. Grant of copyright license
+representatives, including but not limited to communication on electronic
+mailing lists, source code control systems, and issue tracking systems that are
+managed by, or on behalf of, LabStack for the purpose of discussing and
+improving the work — excluding communication that is conspicuously marked or
+otherwise designated in writing by You as "Not a Contribution".
+
+## 2. Copyright license
+
+Subject to the terms of this Agreement, You grant to LabStack and to recipients
+of software distributed by LabStack a perpetual, worldwide, non-exclusive,
+no-charge, royalty-free, irrevocable copyright license to reproduce, prepare
+derivative works of, publicly display, publicly perform, sublicense, and
+distribute Your Contribution and such derivative works.
+
+## 3. Patent license
+
+Subject to the terms of this Agreement, You grant to LabStack and to recipients
+of software distributed by LabStack a perpetual, worldwide, non-exclusive,
+no-charge, royalty-free, irrevocable (except as stated in this section) patent
+license to make, have made, use, offer to sell, sell, import, and otherwise
+transfer Your Contribution, where such license applies only to those patent
+claims licensable by You that are necessarily infringed by Your Contribution
+alone or by combination of Your Contribution with the work to which You
+submitted it.
 
-You grant to LabStack and to recipients of software distributed by LabStack a
-perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-copyright license to reproduce, prepare derivative works of, publicly display,
-publicly perform, sublicense, and distribute Your contributions and such
-derivative works.
+If any entity institutes patent litigation against You or any other entity
+alleging that Your Contribution, or the work to which You contributed it,
+constitutes direct or contributory patent infringement, then any patent
+licenses granted to that entity under this Agreement for that Contribution or
+work terminate as of the date such litigation is filed.
 
-You further grant LabStack the right to license Your contributions, including
-under licenses other than the license Fanout currently uses, and to relicense
-Fanout in whole or in part.
+## 4. Right to relicense
 
-## 3. Grant of patent license
+You grant LabStack the right to license Your Contribution under any license
+terms, including licenses other than the Apache License, Version 2.0, and to
+distribute Your Contribution as part of proprietary or commercially licensed
+offerings.
 
-You grant to LabStack and to recipients of software distributed by LabStack a
-perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-(except as stated in this section) patent license to make, have made, use, offer
-to sell, sell, import, and otherwise transfer Fanout. This license applies only
-to those patent claims licensable by You that are necessarily infringed by Your
-contribution alone or by combination of Your contribution with Fanout.
+This clause exists so that a LabStack project can offer a commercially
+licensed edition without needing to locate and re-negotiate with every past
+contributor. It does not restrict Your own use of Your Contribution, and it
+does not withdraw any release already made under an open source license: every
+version of a LabStack project published under the Apache License, Version 2.0,
+remains available under that license permanently.
 
-If any entity institutes patent litigation against You or any other entity
-alleging that Your contribution, or Fanout to which You contributed, constitutes
-direct or contributory patent infringement, then any patent licenses granted to
-that entity under this agreement for that contribution or for Fanout terminate
-as of the date such litigation is filed.
