+AI-assisted contribution policy
+===============================
+
+pretix is maintained by humans.
+Every discussion, issue, and pull request is read and reviewed by humans (and sometimes machines, too).
+We ask you to respect the time and effort put in by these humans by not sending low-effort, unqualified work, since it puts the burden of validation on the maintainer.
+
+Therefore, the pretix project has strict rules for AI usage:
+
+- **All AI usage in any form must be disclosed.** You must state the tool you used (e.g. Claude Code, Cursor, Amp) along with the extent that the work was AI-assisted.
+
+- **The human-in-the-loop must fully understand all code.** If you can't explain what your changes do and how they interact with the greater system without the aid of AI tools, do not contribute to this project.
+
+- **Issues and discussions can use AI assistance but must have a full human-in-the-loop.** This means that any content generated with AI must have been reviewed and edited by a human before submission. AI is very good at being overly verbose and including noise that distracts from the main point. Humans must do their research and trim this down.
+
+- **No AI-generated media is allowed (art, images, videos, audio, etc.).** Text and code are the only acceptable AI-generated content, per the other rules in this policy.
+
+- **Bad AI drivers will be excluded from the project.** People who produce bad contributions that are clearly AI (slop) will be blocked from our organization without warning.
+
+This policy was inspired by the `ghostty project`_.

+Discussion & Design
+-------------------
+
+pretix is a large and mature project with more of a decade of history and hopefully many more decades to come.
+Keeping pretix in good shape over long timeframes is first and foremost a fight against complexity.
+With every additional feature, complexity grows, and both features and complexity are hard to remove.
+
+Even if you are doing the initial work of the contribution, accepting the contribution is not free for us.
+Not only will we need to maintain the feature, but every feature adds cost to the maintenance of every other feature it interacts with, and every feature adds effort for users to understand how pretix works.
+Therefore, we must carefully select what features we add, based on how well they fit the system in general and of how much use they will be to our larger user base.
+
+We strongly ask you to **create a discussion on GitHub for every new feature idea** outlining the use case and the proposed implementation design.
+Pull requests without prior discussion will likely just be closed.
+
+For bug fixes and very minor changes, you can skip this step and open a PR right away.

+Adding permissions
+------------------
+
+Plugins can add permissions through the ``register_event_permission_groups`` and ``register_organizer_permission_groups``.
+We recommend to use this only for very significant permissions, as the system will become less usable with too many
+permission levels, also because the team page will show all permission options, even those of disabled plugins.
+
+To register your permissions, you need to register a **permission group** (often representing an area of functionality
+or a key model). Below that group, there are **actions**, which represent the actual permissions. Permissions will be
+generated as ``<group_name>:<action>``. Then, you need to define **options** which are the valid combinations of the
+actions that should be possible to select for a team. This two-step mechanism exists to provide a better user experience
+and avoid useless combinations like "write but not read".
+
+Example::
+
+    @receiver(register_event_permission_groups)
+    def register_plugin_event_permissions(sender, **kwargs):
+        return [
+            PermissionGroup(
