# Contributor License Agreement

Thank you for contributing to observability-mcp. To keep the project
sustainable as open core, every contributor must agree to this Contributor
License Agreement (CLA) before a contribution can be merged. You accept it by
commenting the sign-off phrase on your pull request when the CLA bot asks.

This CLA is adapted from the Apache Individual CLA, **with an explicit
relicensing/sublicensing grant** so the project can offer commercial and
source-available editions.

By contributing, You agree to the following for each Contribution You submit:

1. **Copyright license.** You grant the project owner (Thomas Tischner) and
   recipients of software distributed by the project 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.

2. **Patent license.** You grant the project owner and recipients a
   perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable
   (except as stated below) 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 with
   the project. If any entity institutes patent litigation alleging that the
   project or a Contribution constitutes patent infringement, the patent
   licenses granted to that entity under this CLA terminate.

3. **Relicensing / sublicensing (the open-core grant).** You agree that the
   project owner may license, relicense, and sublicense Your Contributions
   and any derivative works, in whole or in part, under **any license terms
   the project owner chooses, including proprietary, commercial, or
   source-available terms (for example the Functional Source License), and
   without any obligation to release such derivative works under an
   open-source license.** This right is in addition to, and does not limit,
   the open-source license under which the project is currently distributed
   (Apache-2.0).

4. **Original work / authority.** Each Contribution is either Your original
   creation or You have the right to submit it under this CLA. If Your
   employer has rights to intellectual property You create, You represent
   that You are authorized to submit the Contribution, or that Your employer
   has waived such rights. You must identify any third-party-licensed
   material included in a Contribution.

5. **No warranty.** Contributions are provided "as is", without warranty of
   any kind.

This is a CLA, **not a DCO**: a `Signed-off-by` line only certifies origin
and does **not** grant the relicensing rights in clause 3, which the
open-core model requires. `Signed-off-by` is optional and not enforced.
