 The full product aims for clear live command/outcome feedback, simple charging
 and useful notifications. Those goals do not remove the current native release

-Sourceful develops this project. Fredrik owns FTW's product direction in
-[the shared vision](https://github.com/srcfl/ftw/blob/master/VISION.md). External users submit
-[issues](https://github.com/srcfl/ftw-app/issues) with bugs, needs and evidence.
-We do not accept external pull requests, including documentation changes.
-Acceptance of an issue does not invite an external implementation PR.
-
-Describe the expected result, what happened, the version and relevant
-hardware. You do not need to write code. Keep credentials, keys and private
-site data out of public reports. Sourceful selects and implements changes.
-
-Existing license rights and copyright attributions remain unchanged.
-Sourceful implementation PRs should state the user need, coordinate overlap,
-include relevant verification and follow the repository's development guide.
+Sourceful maintains this repository. Fredrik owns FTW's direction in
+[the shared vision](https://github.com/srcfl/ftw/blob/master/VISION.md).
+External PRs are welcome, preferably based on an
+[issue](https://github.com/srcfl/ftw-app/issues). Small fixes need no separate issue.
+
+Broad product or architecture ideas may start as short Markdown PRs in the
+PR description or relevant maintained docs. Mark proposed behaviour as
+proposed. Concrete fixes can include code and tests. Keep task breakdowns
+and agent scratch notes out of the repository.
+
+Work is agentic first: give people and agents a clear problem, scope,
+reproducible test steps and actual results. Check agent output before
+submitting it. Test changed behaviour and review changed UI in a browser.
+Hardware claims need relevant hardware evidence; distinguish simulation
+from physical tests and state missing checks. Docs need no hardware tests.
+Follow the repository guide and coordinate overlap with open PRs.
+
+Sourceful reviews and maintains changes. A contribution grants no merge,
+release or deployment authority. Existing license rights and attribution
+remain unchanged. See [FTW's contribution guide](https://github.com/srcfl/ftw/blob/master/CONTRIBUTING.md).
