+## About the ownCloud OSPO
+
+The [Kiteworks Open Source Program Office](https://kiteworks.com/opensource), operating under
+the [ownCloud](https://owncloud.com) brand, launched on May 5, 2026, to steward the open source
+ecosystem around ownCloud's products. The OSPO ensures transparent governance, license compliance,
+community health, and sustainable collaboration between the open source community and
+[Kiteworks](https://www.kiteworks.com), which acquired ownCloud in 2023.

+For questions about the OSPO or licensing, contact ospo@kiteworks.com.
+
+### License Migration to Apache 2.0
+
+The OSPO is driving a strategic relicensing of ownCloud repositories toward the
+[Apache License 2.0](https://www.apache.org/licenses/LICENSE-2.0), following
+the [Apache Software Foundation's third-party license policy](https://www.apache.org/legal/resolved.html).
+
+Individual repositories will migrate as their audit is completed. The LICENSE file
+in each repo reflects its **current** license status (not the target).
+
+**Current license: AGPL-3.0** (Category X per Apache policy -- cannot be included in Apache-2.0 works).
+
+Migration prerequisites for this repository:
+
+- **CLA/DCO coverage**: All past contributors must have signed agreements permitting relicensing
+- **Copyleft dependency audit**: All AGPL/GPL dependencies must be replaced or isolated
+- **KDE heritage review**: Any code with KDE-era copyrights requires legal analysis
+- **Complete relicensing**: AGPL-3.0 is a strong copyleft license; migration requires full relicensing of all files, not just a header change

+# agents.md -- Notes
+
+## Repository Overview
+
+Distraction-free note-taking app for ownCloud Server with a RESTful API. Licensed under AGPL-3.0. PHP backend with JavaScript frontend.
+
+## Architecture & Key Paths
+
+- `controller/` -- HTTP controllers
+- `service/` -- Business logic services
+- `db/` -- Database mappers and entities
+- `js/` -- Frontend JavaScript
+- `css/` -- Stylesheets
+- `templates/` -- Server-side templates
+- `appinfo/` -- ownCloud app metadata
+- `l10n/` -- Translation files
+- `tests/` -- Unit and integration tests
+- `Makefile` -- Build and test automation
+- `composer.json` -- PHP dependencies
+
+## Development Conventions
+
+- PHP code follows ownCloud coding standards (phpcs)
+- Static analysis with PHPStan
+
+## Build & Test Commands
+
+```bash
+make build # Build the app
+make test-php-unit # Run PHP unit tests
+make test-php-integration # Run PHP integration tests
+make test-php-style # Check PHP code style
+make dist # Create distribution package
+```
+
+## Important Constraints
+
+- Licensed under AGPL-3.0 (copyleft). Apache 2.0 migration planned.
+- All contributions require a DCO sign-off.
+
+
+## OSPO Policy Constraints
+
+### GitHub Actions
+- **Only** use actions owned by `owncloud`, created by GitHub (`actions/*`), verified on the GitHub Marketplace, or verified by the ownCloud Maintainers.
+- Pin all actions to their full commit SHA (not tags): `uses: actions/checkout@ # vX.Y.Z`
+- Never introduce actions from unverified third parties.
+
+### Dependency Management
+- Dependabot is configured for automated dependency updates.
+- Review and merge Dependabot PRs as part of regular maintenance.
+- Do not introduce new dependencies without discussion in an issue first.
+
+### Git Workflow
+- **Rebase policy**: Always rebase; never create merge commits. Use `git pull --rebase` and `git rebase` before pushing.
+- **Signed commits**: All commits **must** be PGP/GPG signed (`git commit -S -s`).
+- **DCO sign-off**: Every commit needs a `Signed-off-by` line (`git commit -s`).
+- **Conventional Commits & Squash Merge**: Use the [Conventional Commits](https://www.conventionalcommits.org/) format where the repository enforces it. Many repos use squash merge, where the PR title becomes the commit message on the default branch — apply Conventional Commits format to PR titles as well. A reusable GitHub Actions workflow enforces this.
+
+## Context for AI Agents
+
+Standard OC10 app with controller/service/db architecture. The REST API is documented in the wiki. Notes are stored as plain text files in user cloud storage.
