-# ownCloud Shell Integrations for Dolphin
+# ownCloud Shell Integration for Dolphin
 
-This is the ownCloud shell integration for the great KDE Dolphin in KDE Frameworks 6.

-It adds overlay icons for local directories that are synced with ownCloud server.
-The icons visualize the sync state of the files.

-Also, a context menu item is added to Dolphins context menu for synced diretories which
-allows to access ownCloud specific functions for the file item such as sharing.
+This is the ownCloud shell integration plugin for KDE Dolphin (KDE Frameworks 6). It adds overlay icons to local directories synced with ownCloud Server, visualizing the sync state of files (synced, syncing, error). It also provides a context menu entry in Dolphin for accessing ownCloud-specific functions such as sharing.
 
+## Part of Desktop Client
 
+This shell integration is a companion to the [ownCloud Desktop Client](https://github.com/owncloud/client). It provides file manager integration for KDE Plasma users. Related repositories include the [Nautilus integration](https://github.com/owncloud/client-desktop-shell-integration-nautilus) and [shared icon resources](https://github.com/owncloud/client-desktop-shell-integration-resources).
 
+> **Note:** This repository is currently in Maintenance mode. It receives bug fixes and compatibility updates but no new feature development.

+
+### Workflow
+
+- **Rebase Early, Rebase Often!** We use a rebase workflow. Always rebase on the target branch before submitting a PR.
+- **Dependabot**: Automated dependency updates are managed via Dependabot. Review and merge dependency PRs promptly.
+- **Signed Commits**: All commits **must** be PGP/GPG signed. See [GitHub's signing guide](https://docs.github.com/en/authentication/managing-commit-signature-verification).
+- **DCO Sign-off**: Every commit must carry a `Signed-off-by` line:
+  ```
+  git commit -s -S -m "your commit message"
+  ```
+- **GitHub Actions Policy**: Workflows may only use actions that are (a) owned by `owncloud`, (b) created by GitHub (`actions/*`), or (c) verified in the GitHub Marketplace.
+
+## Security
+
+**Do not open a public GitHub issue for security vulnerabilities.**

+## 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: GPL-2.0** (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 GPL dependencies must be replaced or isolated
+- **KDE heritage review**: Any code with KDE-era copyrights requires legal analysis
+- **Complete relicensing**: GPL-2.0 is a strong copyleft license; migration requires full relicensing of all files

+# AI Agent Guidelines for Shell Integration (Dolphin)
+
+This file provides context for AI coding agents (Claude Code, GitHub Copilot, Cursor, etc.) working in this repository.
+
+## Repository Overview
+- **Product family:** Desktop Client
+- **Primary language(s):** C++
+- **Build system:** CMake
+- **Test framework:** None detected
+- **CI system:** GitHub Actions
+
+## Architecture & Key Paths
+- `src/` - C++ source code for the Dolphin plugin
+- `CMakeLists.txt` - CMake build configuration
+- `COPYING` - GPL-2.0 license
+
+## Development Conventions
+- **Branching:** master
+- **Commit messages:** DCO sign-off required (`git commit -s`)
+- **Code style:** EditorConfig
+- **PR process:** Open a PR against master. All CI checks must pass.
+
+## Build & Test Commands
+```bash
+# Build
+mkdir build && cd build
+cmake ..
+cmake --build .
+
+# Test
+Not detected
+
+# Lint
+Not detected
+```
+
+## Important Constraints
+- All code contributions must be compatible with the **GPL-2.0** license
+- Do not introduce new **copyleft-licensed dependencies** (GPL, AGPL, LGPL, MPL) without explicit discussion in an issue first. This is especially important for repos migrating to Apache 2.0.
+- Do not introduce new dependencies without discussion in an issue first
+- Requires KDE Frameworks 6 and Qt 6
+- This repo is in Maintenance mode
+
+
+## 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@<SHA> # 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
+- Match existing code style
+- Do not refactor unrelated code in the same PR
+- Write tests for new functionality
+- Keep PRs focused and atomic
+- Icons are provided by the separate client-desktop-shell-integration-resources repository
