release: v0.4.0

Updated sync_wiki.py to use correct Gitea 1.26 wiki API: POST /wiki/new for create, PATCH /wiki/page/{sub_url} for update, GET /wiki/pages returns sub_url. Tests updated to match.

Closes GRM-36

+```
+
+## Architecture
+
+- **Python CLI** (`src/gitea_runner_manager/`) — Click-based CLI that delegates to Ansible
+- **Ansible Role** (`ansible/roles/gitea-runner/`) — Idempotent role for rootless Docker runner setup
+- **CI Scripts** (`scripts/`) — Automation for auto-merge, post-merge, release, publishing, molecule distribution, PR reviews, failure notifications
+- **Versioning** (`cliff.toml`) — git-cliff configuration for automated semver versioning from conventional commits
+
+## PR Workflow (Mandatory)
+
+Every change to master goes through this workflow. No exceptions.
+
+### Branch Protection (Required Gitea Settings)
+
+Configure the following branch protection rules for `master` in Gitea repo settings:
+- **Require pull request**: No direct pushes to master
+- **Require approval review**: At least 1 `APPROVE` review before merge
+- **Require status checks**: CI quality + molecule tests must pass
+- **Block force pushes**: No history rewriting on master
+
+The auto-merge workflow enforces the APPROVE review check programmatically
+as a defense-in-depth measure, but branch protection is the primary gate.
+
+### 1. Create Vikunja Task
+Create a task in Vikunja project 6 to get a `GRM-N` identifier.
+
+### 2. Create Branch
+```bash
+git checkout master && git pull
+git checkout -b GRM-N-short-description
+```
+
+### 3. Implement Changes
+- Write code following conventions below
+- Write/update tests (100% coverage required)
+- Update documentation (CHANGELOG, README, AGENTS.md as needed)
+
+### 4. Commit (Conventional Commits)
+Branch commits use conventional commit format (no `GRM-N:` prefix):
+```
+feat: add new feature
+fix: resolve bug
+docs: update README
+```
+
+### 5. Push and Create PR
+- **PR title format**: `GRM-N: <vikunja task title>` (must match the Vikunja task title exactly)
+- PR body: summary of changes, `Closes GRM-N`
+- Add `ready-to-merge` label **only after review is complete**
+
+### 6. Review the PR (Mandatory — Before Adding ready-to-merge Label)
+Review the full diff (`git diff master...HEAD`) focusing on:
+
+- **Functional completeness**: Does the code do what it claims? Are all requirements met?
+- **Edge cases**: Are boundary conditions, empty inputs, error paths handled?
+- **Technical excellence**:
+  - Architecture compliance and evolution
+  - Single Responsibility Principle (SRP)
+  - Deduplication (no copy-paste, single source of truth)
+  - Code smells detection and removal
+  - Best industry practices
+  - Industry-grade code quality
+  - Reusability
+  - Clean code
+  - Readability
+  - Maintainability
+  - Extensibility
+- **Performance**: No unnecessary allocations, O(n) vs O(n²), efficient data structures
+- **Security**: No secrets in logs/process list, input validation, no injection vectors
+- **User experience**: Clear error messages, intuitive CLI flags, helpful output
+- **Documentation**: Completeness and relevance of docs, CHANGELOG entries, AGENTS.md updates
+
+Post review comments using `scripts/ci/review_pr.py`:
+```bash
+REPO_TOKEN=<token> python3 scripts/ci/review_pr.py <pr_number> <owner/repo> \
+  --event REQUEST_CHANGES \
+  --body "Review summary" \
+  --comments-json comments.json
+```
+
+### 7. Address Review Comments
+Fix each comment one by one, commit, and push. Re-review until satisfied.
+
+### 8. Approve and Merge
+Once all comments are addressed:
+```bash
+REPO_TOKEN=<token> python3 scripts/ci/review_pr.py <pr_number> <owner/repo> \
+  --event APPROVE \
+  --body "All comments addressed. LGTM."
+```
+
+Then add the `ready-to-merge` label. The auto-merge workflow will:
+1. **Validate** PR title format and match against Vikunja task title
+2. **Check** that at least one APPROVE review exists
+3. Wait for all CI checks to pass
+4. Squash-merge with title: `GRM-N <conventional commit message>` (space-separated)
+5. The post-merge workflow marks the Vikunja task as done
+6. The release workflow automatically versions, tags, and publishes (see below)
+
+### CI Path Filtering
+
+The CI workflow includes a `detect-changes` job that checks whether any files
+under `ansible/` or `.ansible-lint` have changed. If no Ansible files are
+changed, molecule tests are skipped — this prevents non-Ansible changes
+(e.g., Python scripts, workflow YAML, docs) from being blocked by molecule
+test infrastructure flakiness.
+
+### Dynamic Runner Discovery
+
+Molecule tests are distributed across available Gitea Actions runners
+dynamically via `scripts/ci/discover_runners.py`. The `discover-runners`
+job queries the Gitea API for runners at all levels (repo, org, instance)
+and generates a dynamic matrix. If the API can't see instance-level runners
+(no admin scope), it falls back to the `MOLECULE_RUNNERS` repo variable,
+then to a default of 3.
+
+**When adding/removing Gitea runners:**
+1. Repo/org-level runners are auto-detected via the API
+2. For instance-level runners, update the `MOLECULE_RUNNERS` repo variable
+3. The workflow automatically scales the matrix to match available runners
+
+### Automated Release Pipeline
+
+After a PR is merged to master, the release pipeline runs automatically:
+
+1. **Release workflow** (`.gitea/workflows/release.yml`):
+   - Triggers on push to master
+   - Sets up full dev environment (`make setup`) so lint and tests can run
+   - Runs `scripts/ci/release.py` which:
+     - **Checks for user-facing changes** via `scripts/ci/classify_changes.py` — if only
+       workflow/infrastructure files changed (`.gitea/`, `scripts/`, `docs/`, `tests/`,
+       `AGENTS.md`, `Makefile`, etc.), the release is **skipped entirely** — no version
+       bump, no tag, no publish. This prevents unnecessary releases for CI/docs-only changes.
+     - Uses **git-cliff** to calculate the next semver version from conventional commits
+     - Updates `__version__` in `src/gitea_runner_manager/__init__.py` (single source of truth)
+     - Updates `CHANGELOG.md` with the new version section
+     - **Runs `make lint-ruff` and `make pytest-cov`** to verify the release is healthy
+     - If lint or tests fail, **aborts immediately** — no commit, no tag
+     - Commits with `release: vX.Y.Z` prefix (cleaner than `chore(release):`)
+     - Creates an annotated tag `vX.Y.Z` on the release commit
+     - Pushes both the commit and tag to master
+   - `--skip-tests` flag bypasses test verification (emergency use only, not recommended)
+   - Loops are prevented by `has_unreleased_changes` — after a release commit is tagged, the next run finds no unreleased changes and exits
+   - On failure, creates a Gitea issue via `scripts/ci/notify_failure.py`
+
+### Smart CI: User-Facing vs Workflow-Only Changes
+
+Not all changes require the full CI pipeline or a new release. The project
+classifies changes into two categories using `scripts/ci/classify_changes.py`:
+
+**Classification strategy (safe-by-default):** Any file NOT in the explicit
+workflow-only allowlist is treated as user-facing. This prevents new file
+types from accidentally skipping releases.
+
+**Workflow-only paths** (infrastructure → no release needed):
+- `.gitea/**` — Gitea Actions workflows
+- `scripts/ci/**` — CI/CD automation scripts
+- `scripts/setup.sh`, `scripts/molecule_all.sh`, `scripts/__init__.py` — Shell scripts and package init
+- `docs/**` — Documentation
+- `tests/**` — Test files
+- `AGENTS.md`, `README.md`, `CHANGELOG.md`, `TROUBLESHOOTING.md` — Project docs
+- `Makefile`, `cliff.toml`, `.pre-commit-config.yaml`, `.ansible-lint` — Config
+- `.env.example`, `.gitignore`, `.ruff.toml` — Config
+- `hooks/**` — Git hooks
+
+**User-facing paths** (tool changes → release needed) — everything else:
+- `src/gitea_runner_manager/**` — Python CLI source
+- `ansible/**` — Ansible role
+- `pyproject.toml` — Package metadata
+- `scripts/check_test_speed.py`, `scripts/configure_repo.py`, `scripts/install_checkmake.py` — Dev tools
+- Any new file type not in the allowlist
+
+**Script directory structure:**
+- `scripts/` — Dev tools (run locally by developers): `check_test_speed.py`, `configure_repo.py`, `install_checkmake.py`, `setup.sh`, `molecule_all.sh`
+- `scripts/ci/` — CI/CD automation (run by workflows): `release.py`, `publish.py`, `auto_merge.py`, `classify_changes.py`, `doc_coverage.py`, `sync_wiki.py`, etc.
+
+**CI behavior based on classification:**
+- **Molecule tests**: Only run when `ansible/` or `.ansible-lint` files change
+- **Release dry-run**: Only runs when user-facing files change
+- **Quality job** (lint, unit tests, coverage, doc-coverage): Always runs
+- **Release workflow**: Skips entirely when no user-facing files changed since last tag
+
+**AI agents must follow these rules:**
+- When working on workflow/CI/docs-only changes, use `ci:` or `docs:` commit prefixes
+- Do NOT bump the version or create tags for workflow-only changes
+- The `classify_changes.py` script enforces this automatically — no manual intervention needed
+- When adding a new CI script, place it in `scripts/ci/`. Dev tools go in `scripts/`.
+
+2. **Publish workflow** (`.gitea/workflows/publish.yml`):
+   - Triggers on tag push (`v*`)
+   - Validates `PYPI_TOKEN` is set (warns if missing)
+   - Builds the Python package
+   - Optionally publishes to PyPI (if `PYPI_TOKEN` is set)
+   - Creates a Gitea release with git-cliff-generated release notes
+   - On failure, creates a Gitea issue via `scripts/ci/notify_failure.py`
+
+### git-cliff Commit Preprocessing
+
+Merge commits on master have the format `GRM-N <conventional commit>`. The
+`GRM-N ` prefix is not a valid conventional commit prefix, so `cliff.toml`
+includes a `commit_preprocessors` entry that strips it before parsing. This
+ensures all merged work appears in the changelog.
+
+### Version Bumping Rules (git-cliff)
+
+| Commit type | Version bump |
+|-------------|-------------|
+| `feat:` | minor (0.X.0) |
+| `fix:` | patch (0.0.X) |
+| `feat!:` or `BREAKING CHANGE` | minor (pre-1.0: major would be 1.0.0) |
+| `chore:`, `ci:`, `docs:` | no bump (excluded by cliff.toml) |
+
+The version source is `__version__` in `src/gitea_runner_manager/__init__.py`, read by setuptools via `dynamic = ["version"]` in `pyproject.toml`. The release script only updates `__init__.py` — no need to touch `pyproject.toml`. `grm --version` reports this version.
+
+### Title Format Summary
+
+| What | Format | Example |
+|------|--------|---------|
+| Branch name | `GRM-N-short-description` | `GRM-33-add-pr-review-step` |
+| Branch commits | `<conventional commit>` | `feat: add review script` |
+| PR title | `GRM-N: <vikunja task title>` | `GRM-33: Add mandatory PR review step` |
+| Merge commit | `GRM-N <conventional commit>` | `GRM-33 feat: add review script` |
+
+## Key Conventions
+
+- Python 3.12+ required (ruff/pyright target `py312`)
+- 100% test coverage required (`--cov-fail-under=100`)
+- Conventional commits on feature branches (no `GRM-N:` prefix)
+- Branch names must include `GRM-N` task ID
+- Line length: 120 chars
+- Secrets are passed via temp JSON files, never on the command line (CWE-214)
+- CI triggers only on `opened` and `synchronize` PR events (not `labeled`)
+
+## Ansible Role Structure
+
+```
+main.yml → systemd_check → user_setup → rootless_docker → install_runner → prune → integration_test
+```
+
+- `install_runner.yml` handles: download, config, validate, register, service
+- `main.yml` handles: prune, integration_test (NOT install_runner — avoids duplicates)
+- `systemctl --user` tasks must be guarded by `docker_rootless_setup`
+- Template creation tasks are NOT guarded by `docker_rootless_setup` (they just create files)
+
+## Molecule Scenarios
+
+6 scenarios: `default`, `multi-instance`, `lifecycle`, `template-content`, `deregister`, `update`
+4 platforms: `ubuntu-2204`, `ubuntu-2404`, `debian-12`, `archlinux`
+Platform list is defined in `scripts/ci/distribute_molecule.py` (single source of truth)
+
+## Known Issues
+
+- `ansible-lint` may warn about `command-instead-of-module` for `systemctl --user` calls — this is expected (systemd module doesn't support user services) and skipped in `.ansible-lint`
+- Molecule Docker driver may print "Event loop is closed" warnings on interrupt — harmless
+
+## Documentation-as-Code
+
+All documentation lives in `/docs/` and is synced to the Gitea wiki automatically.
+

+
+### Wiki Sync
+
+- **On merge to master**: `sync-wiki.yml` workflow runs `scripts/ci/sync_wiki.py` which pushes all `/docs/` content to the Gitea wiki via API
+- **On release tag**: Same sync runs, plus the wiki is tagged with the release version
+- `mapping.json` maps each file path to a wiki page title (e.g., `user/getting-started.md` → `Getting-Started`)
+- README.md is a lean entry point with links to the wiki — no detailed content
+
+### Documentation Coverage
+
+- `scripts/ci/doc_coverage.py` checks that all CLI commands, Python modules, and CI scripts are documented
+- Runs as a CI step in the quality job
+- Goal: 100% coverage for public CLI commands and major architectural components
+
+### Updating Documentation
+
+1. Edit files in `/docs/`
+2. If adding a new page, add it to `docs/mapping.json`
+3. Commit and create a PR (standard PR workflow)
+4. On merge, wiki is automatically synced

+
+## [Unreleased]
+
+### Added
+
+- **Automated semver versioning and releases**: `scripts/release.py` — CI script that uses git-cliff to calculate the next version from conventional commits, update version files, create a release commit, tag, and push.
+- `cliff.toml` — git-cliff configuration for conventional commit parsing, semver bumping, and changelog generation.
+- Release workflow (`.gitea/workflows/release.yml`) — triggers on push to master, runs `scripts/release.py` to automatically version and tag releases.
+- `publish.py` now uses git-cliff to generate release notes for Gitea releases (falls back to generic message if git-cliff is not available).
+- `pyproject.toml` now uses `dynamic = ["version"]` with setuptools `attr` to source version from `__init__.py` (single source of truth — release script only updates `__init__.py`).
+- **Mandatory PR review step**: `scripts/review_pr.py` — CLI to post Gitea PR reviews (COMMENT, APPROVE, REQUEST_CHANGES) with inline comments via `--comments-json` or `--comments-stdin`.
+- `GiteaClient.get_pr_files`, `GiteaClient.get_pr_commits`, `GiteaClient.create_review` — API methods for PR review workflow.
+- `VikunjaClient.get_task` — fetch a single task by numeric ID.
+- PR title format: `GRM-N: <vikunja task title>` (colon-separated, human-friendly).
+- Merge commit format: `GRM-N <conventional commit message>` (space-separated, conventional).
+- `auto_merge.py` now extracts the conventional commit message from PR commits and constructs the merge title as `GRM-N <conventional commit>`.
+- `post_merge.py` `extract_conventional_msg` now handles both legacy (`GRM-N: <msg>`) and current (`GRM-N <msg>`) merge commit formats.
+- Full PR workflow documented in `AGENTS.md` and `README.md` (Vikunja task → branch → implement → commit → PR → review → address comments → approve → merge).
+
+### Changed
+
+- Parameterized all hardcoded configuration values as Ansible variables in `defaults/main.yml`:
+  - `gitea_runner_data_dir` — Runtime data directory
+  - `gitea_runner_config_dir` — Config directory
+  - `gitea_runner_binary_path` — Binary install path
+  - `gitea_runner_prune_until` — Prune age filter
+  - `gitea_runner_prune_schedule` — Prune timer schedule
+  - `gitea_runner_prune_label` — Docker label for pruning
+  - `gitea_runner_service_restart_sec` — systemd restart interval
+  - `gitea_runner_service_user` — Service user
+  - `gitea_runner_log_level` — Runner log level
+  - `gitea_runner_container_label` — Container label
+  - `gitea_runner_file` — Runner metadata file
+  - `docker_gpg_key_path` — Docker GPG key path
+- Added `console_scripts` entry point in `pyproject.toml` (`grm = "gitea_runner_manager.cli:cli"`).
+- Added shared `molecule/common/prepare.yml` to eliminate duplicated prepare playbooks.
+- Extracted repeated systemd availability check into `tasks/systemd_check.yml`.
+- Added idempotence checks to all Molecule scenarios.
+- Comprehensive README overhaul with Architecture, Configuration, Development, Testing, and Troubleshooting sections.
+- API URLs and repo configuration in `config.py` are now overridable via environment variables (`GRM_GITEA_API_URL`, `GRM_VIKUNJA_API_URL`, `GRM_REPO_OWNER`, `GRM_REPO_NAME`, `GRM_VIKUNJA_PROJECT_ID`).
+- `remove-runner.yml` now disables lingering and removes subuid/subgid entries for complete cleanup.
+
+### Security
+
+- **Critical fix**: Registration tokens and admin tokens are no longer passed via `--extra-vars` on the command line (CWE-214). Extra-vars are now written to a temporary JSON file with `0600` permissions and passed via `--extra-vars @tempfile`, which is deleted after execution. This prevents secrets from being visible in the process list (`ps aux`).
+
+### Changed
+
+- Replaced legacy runner terminology with `gitea_runner` / `gitea-runner` / `Gitea Runner`.
+- Updated default Docker image from `gitea/gitea_runner` to `gitea/runner`.
+- `Makefile` now uses the installed `grm` console script instead of `python grm`.
+- `pyproject.toml` ruff and pyright target versions updated from `py311` to `py312` to match `requires-python = ">=3.12"`.
+- `BRANCH_PROTECTION_CONFIG` updated with correct Gitea Actions status check contexts (including `(pull_request)` suffix) and `required_approvals: 0` for auto-merge.
+- `CONVENTIONAL_RE` no longer matches `BREAKING CHANGE` as a commit type (it is a footer, not a type).
+- `rootless_docker.yml` apt cache update now only runs when the Docker repo file changes (idempotent, but always refreshes on first add).
+- `service.yml` and `prune.yml` template creation tasks are not guarded by `docker_rootless_setup` (templates just create files, they don't need Docker; molecule tests set `docker_rootless_setup: false` but still verify the service file exists).
+- `molecule_all.sh` now sources the platform list from `distribute_molecule.py` to avoid duplication.
+
+### Removed
+
+- Deleted `setup.py` (redundant with `pyproject.toml`).
+- Deleted `grm` shell entrypoint script (replaced by `console_scripts`).
+- Deleted `initial-plan.md` and `tests/integration/test_provision.py` (dead code).
+- Removed empty `__init__.py` files from `tests/` directories.
+- Removed unused `runner_validated` fact from `validate.yml`.
+- Removed duplicate `prune.yml` and `integration_test.yml` includes from `install_runner.yml` (already included from `main.yml`).
+- Removed dead `tasks/config.yml` (never included by any playbook).
+- Removed dead `templates/gitea-runner.service.j2` (legacy system-level service, replaced by rootless `gitea-runner-user.service.j2`).
+- Removed dead "Reload systemd" handler (system-level reload, never notified, wrong scope for user services).
+- Removed dead `scripts/run_molecule_parallel.py` and its test (replaced by `molecule_ci_guard.py`).
+
+### Fixed
+
+- Molecule idempotence failures caused by non-idempotent service restart.
+- Missing `/etc/docker` directory handling in Molecule tests.
+- `ansible-lint` formatting warnings (yaml empty lines).
+- Verify playbooks now explicitly load role defaults so parameterized variables are available during verification.
+- Duplicate execution of prune and integration test tasks during installation (were included from both `main.yml` and `install_runner.yml`).
+- apt cache update reporting `changed` on every run due to `cache_valid_time: 0`.

+
+## Branch Naming
+
+All feature branches **must** include a `GRM-N` prefix corresponding to the Vikunja task identifier. Examples:
+
+- `GRM-19`
+- `GRM-19-fix-bug`
+- `GRM-42-add-update-command`
+
+The `GRM-N` prefix is mandatory — CI extracts it for merge messages and Vikunja updates.
+
+## Commit Format
+
+### Feature branches
+Use **conventional commits** on feature branches:
+
+```
+feat: add new command
+fix: resolve timeout issue
+chore: update dependencies
+docs: improve README
+```
+
+Allowed types: `feat`, `fix`, `chore`, `docs`, `style`, `refactor`, `perf`, `test`, `ci`, `build`, `revert`, `BREAKING CHANGE`.
+
+**Do NOT** include the `GRM-N:` prefix in commit messages on feature branches.
+
+### Master branch (squash merges)
+Squash commits on `master` must follow:
+
+```
+GRM-N: <conventional commit message>
+```
+
+Example: `GRM-24: fix: resolve molecule idempotence`.
+
+This format is enforced by the auto-merge workflow, which validates the PR title is a conventional commit before squash-merging and prepending the task ID.
+
+## Local Testing
+
+```bash
+make test-all    # Runs pytest-cov + molecule
+make lint-all    # Runs ruff, pyright, bandit, ansible-lint, checkmake
+make lint-bandit # Security scan with bandit

+make molecule    # All 6 molecule scenarios
+```
+
+## Code Quality
+
+- **ruff**: Line length 120
+- **pyright**: Strict mode
+- **bandit**: Security scan for Python code (no high/medium severity issues)
+- **Test coverage**: 100% required
+- **ansible-lint**: For all Ansible content

+GNU GENERAL PUBLIC LICENSE
+Version 3, 29 June 2007
+
+Copyright © 2007 Free Software Foundation, Inc. <https://fsf.org/>
+
+Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
+
+Preamble
+
+The GNU General Public License is a free, copyleft license for software and other kinds of works.
+
+The licenses for most software and other practical works are designed to take away your freedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change all versions of a program--to make sure it remains free software for all its users. We, the Free Software Foundation, use the GNU General Public License for most of our software; it applies also to any other work released this way by its authors. You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for them if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs, and that you know you can do these things.
+
+To protect your rights, we need to prevent others from denying you these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you distribute copies of the software, or if you modify it: responsibilities to respect the freedom of others.
+
+For example, if you distribute copies of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that you received. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.
+
+Developers that use the GNU GPL protect your rights with two steps: (1) assert copyright on the software, and (2) offer you this License giving you legal permission to copy, distribute and/or modify it.
+
+For the developers' and authors' protection, the GPL clearly explains that there is no warranty for this free software. For both users' and authors' sake, the GPL requires that modified versions be marked as changed, so that their problems will not be attributed erroneously to authors of previous versions.
+
+Some devices are designed to deny users access to install or run modified versions of the software inside them, although the manufacturer can do so. This is fundamentally incompatible with the aim of protecting users' freedom to change the software. The systematic pattern of such abuse occurs in the area of products for individuals to use, which is precisely where it is most unacceptable. Therefore, we have designed this version of the GPL to prohibit the practice for those products. If such problems arise substantially in other domains, we stand ready to extend this provision to those domains in future versions of the GPL, as needed to protect the freedom of users.
+
+Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free.
+
+The precise terms and conditions for copying, distribution and modification follow.
+
+TERMS AND CONDITIONS
+
+0. Definitions.
+
+“This License” refers to version 3 of the GNU General Public License.
+
+“Copyright” also means copyright-like laws that apply to other kinds of works, such as semiconductor masks.
+
+“The Program” refers to any copyrightable work licensed under this License. Each licensee is addressed as “you”. “Licensees” and “recipients” may be individuals or organizations.
+
+To “modify” a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy. The resulting work is called a “modified version” of the earlier work or a work “based on” the earlier work.
+
+A “covered work” means either the unmodified Program or a work based on the Program.
+
+To “propagate” a work means to do anything with it that, without permission, would make you directly or secondarily liable for infringement under applicable copyright law, except executing it on a computer or modifying a private copy. Propagation includes copying, distribution (with or without modification), making available to the public, and in some countries other activities as well.
+
+To “convey” a work means any kind of propagation that enables other parties to make or receive copies. Mere interaction with a user through a computer network, with no transfer of a copy, is not conveying.
+
+An interactive user interface displays “Appropriate Legal Notices” to the extent that it includes a convenient and prominently visible feature that (1) displays an appropriate copyright notice, and (2) tells the user that there is no warranty for the work (except to the extent that warranties are provided), that licensees may convey the work under this License, and how to view a copy of this License. If the interface presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.
+
+1. Source Code.
+The “source code” for a work means the preferred form of the work for making modifications to it. “Object code” means any non-source form of a work.
+
+A “Standard Interface” means an interface that either is an official standard defined by a recognized standards body, or, in the case of interfaces specified for a particular programming language, one that is widely used among developers working in that language.
+
+The “System Libraries” of an executable work include anything, other than the work as a whole, that (a) is included in the normal form of packaging a Major Component, but which is not part of that Major Component, and (b) serves only to enable use of the work with that Major Component, or to implement a Standard Interface for which an implementation is available to the public in source code form. A “Major Component”, in this context, means a major essential component (kernel, window system, and so on) of the specific operating system (if any) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it.
+
+The “Corresponding Source” for a work in object code form means all the source code needed to generate, install, and (for an executable work) run the object code and to modify the work, including scripts to control those activities. However, it does not include the work's System Libraries, or general-purpose tools or generally available free programs which are used unmodified in performing those activities but which are not part of the work. For example, Corresponding Source includes interface definition files associated with source files for the work, and the source code for shared libraries and dynamically linked subprograms that the work is specifically designed to require, such as by intimate data communication or control flow between those subprograms and other parts of the work.
+
+The Corresponding Source need not include anything that users can regenerate automatically from other parts of the Corresponding Source.
+
+The Corresponding Source for a work in source code form is that same work.
+
+2. Basic Permissions.
+All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
+
+You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside their relationship with you.
+
+Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
+
+3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.
+
+When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.
+
+4. Conveying Verbatim Copies.
+You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program.
+
+You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
+
+5. Conveying Modified Source Versions.
+You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4, provided that you also meet all of these conditions:
+
+     a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
+
+     b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to “keep intact all notices”.
+
+     c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
+
+     d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate Legal Notices, your work need not make them do so.
+
+A compilation of a covered work with other separate and independent works, which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of a storage or distribution medium, is called an “aggregate” if the compilation and its resulting copyright are not used to limit the access or legal rights of the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the other parts of the aggregate.
+
+6. Conveying Non-Source Forms.
+You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding Source under the terms of this License, in one of these ways:
+
+     a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source fixed on a durable physical medium customarily used for software interchange.
+
+     b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge.
+
+     c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
+
+     d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party) that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source. Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these requirements.
+
+     e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the work are being offered to the general public at no charge under subsection 6d.
+
+A separable portion of the object code, whose source code is excluded from the Corresponding Source as a System Library, need not be included in conveying the object code work.
+
+A “User Product” is either (1) a “consumer product”, which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For a particular product received by a particular user, “normally used” refers to a typical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of use of the product.
+
+“Installation Information” for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued functioning of the modified object code is in no case prevented or interfered with solely because modification has been made.
+
+If you convey an object code work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).
+
+The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when the modification itself materially and adversely affects the operation of the network or violates the rules and protocols for communication across the network.
+
+Corresponding Source conveyed, and Installation Information provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to the public in source code form), and must require no special password or key for unpacking, reading or copying.
+
+7. Additional Terms.
+“Additional permissions” are terms that supplement the terms of this License by making exceptions from one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains governed by this License without regard to the additional permissions.
+
+When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which you have or can give appropriate copyright permission.
+
+Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this License with terms:
+
+     a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or
+
+     b) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices displayed by works containing it; or
+
+     c) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material be marked in reasonable ways as different from the original version; or
+
+     d) Limiting the use for publicity purposes of names of licensors or authors of the material; or
+
+     e) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; or
+
+     f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptions directly impose on those licensors and authors.
+
+All other non-permissive additional terms are considered “further restrictions” within the meaning of section 10. If the Program as you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is a further restriction, you may remove that term. If a license document contains a further restriction but permits relicensing or conveying under this License, you may add to a covered work material governed by the terms of that license document, provided that the further restriction does not survive such relicensing or conveying.
+
+If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of the additional terms that apply to those files, or a notice indicating where to find the applicable terms.
+
+Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated as exceptions; the above requirements apply either way.
+
+8. Termination.
+You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise to propagate or modify it is void, and will automatically terminate your rights under this License (including any patent licenses granted under the third paragraph of section 11).
+
+However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a) provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.
+
+Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by some reasonable means, this is the first time you have received notice of violation of this License (for any work) from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.
+
+Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights from you under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material under section 10.
+
+9. Acceptance Not Required for Having Copies.
+You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, you indicate your acceptance of this License to do so.
+
+10. Automatic Licensing of Downstream Recipients.
+Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with this License.
+
+An “entity transaction” is a transaction transferring control of an organization, or substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the work from the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.
+
+You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example, you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making, using, selling, offering for sale, or importing the Program or any portion of it.
+
+11. Patents.
+A “contributor” is a copyright holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor's “contributor version”.
+
+A contributor's “essential patent claims” are all patent claims owned or controlled by the contributor, whether already acquired or hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a consequence of further modification of the contributor version. For purposes of this definition, “control” includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.
+
+Each contributor grants you a non-exclusive, worldwide, royalty-free patent license under the contributor's essential patent claims, to make, use, sell, offer for sale, import and otherwise run, modify and propagate the contents of its contributor version.
+
+In the following three paragraphs, a “patent license” is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to practice a patent or covenant not to sue for patent infringement). To “grant” such a patent license to a party means to make such an agreement or commitment not to enforce a patent against the party.
+
+If you convey a covered work, knowingly relying on a patent license, and the Corresponding Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. “Knowingly relying” means you have actual knowledge that, but for the patent license, your conveying the covered work in a country, or your recipient's use of the covered work in a country, would infringe one or more identifiable patents in that country that you have reason to believe are valid.
+
+If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate, modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work and works based on it.
+
+A patent license is “discriminatory” if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent license was granted, prior to 28 March 2007.
+
+Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be available to you under applicable patent law.
+
+12. No Surrender of Others' Freedom.
+If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be to refrain entirely from conveying the Program.
+
+13. Use with the GNU Affero General Public License.
+Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3 of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction through a network will apply to the combination as such.
+
+14. Revised Versions of this License.
+The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies that a certain numbered version of the GNU General Public License “or any later version” applies to it, you have the option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software Foundation.
+
+If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy's public statement of acceptance of a version permanently authorizes you to choose that version for the Program.
+
+Later license versions may give you additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to follow a later version.
+
+15. Disclaimer of Warranty.
+THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+16. Limitation of Liability.
+IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+17. Interpretation of Sections 15 and 16.
+If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return for a fee.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively state the exclusion of warranty; and each file should have at least the “copyright” line and a pointer to where the full notice is found.
+
+     grm
+     Copyright (C) 2026  emil
+
+     This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation, either version 3 of the License, or (at your option) any later version.
+
+     This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU General Public License for more details.
+
+     You should have received a copy of the GNU General Public License along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program does terminal interaction, make it output a short notice like this when it starts in an interactive mode:
+
+     grm  Copyright (C) 2026  emil
+     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+     This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, your program's commands might be different; for a GUI interface, you would use an “about box”.
+
+You should also get your employer (if you work as a programmer) or school, if any, to sign a “copyright disclaimer” for the program, if necessary. For more information on this, and how to apply and follow the GNU GPL, see <https://www.gnu.org/licenses/>.
+
+The GNU General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Lesser General Public License instead of this License. But first, please read <https://www.gnu.org/philosophy/why-not-lgpl.html>.

+# Gitea Runner Manager (GRM)
+
+A lean command-line tool to automate the installation, configuration, and lifecycle management of Gitea Actions runners on Arch Linux, Ubuntu, and Debian hosts.
+
+Each runner runs in an isolated **rootless Docker** environment under a dedicated system user, enabling multiple runners to operate in parallel on the same host without conflicts.
+
+> **Pronunciation:** GRM is short for *Gitea Runner Manager*, but say it like **ГРЪМ** (roughly "GRUM") — the Bulgarian word for **thunder**. An open-source project from **Oblachno** (облачно means *cloudy* in Bulgarian).

+## Quick Start
+
+```bash
+git clone https://git.oblachno.oblachno.fyi/oblachno-oss/grm.git
+cd grm
+make setup
+cp .env.example .env  # Edit with your Gitea URL and registration token
+grm install 192.168.1.10 --user ubuntu --key ~/.ssh/id_ed25519 --name prod-runner

+# Troubleshooting
+
+| Symptom | Likely Cause | Solution |
+|---------|-------------|----------|
+| Pre-commit rejects commit message | Missing conventional format or GRM-N prefix present | Use `feat: description` format without `GRM-N:` |
+| `make molecule` fails with `runner_name is undefined` | Verify playbook missing variable | Fixed in Phase 1.1; ensure you're on latest master |
+| CI molecule job fails | Docker not available on runner host | Ensure Gitea runner host has Docker installed and running |
+| Auto-merge doesn't trigger | Label not exactly `ready-to-merge` or CI checks not all green | Verify label spelling; check CI status |
+| Vikunja task not updated after merge | VIKUNJA_TOKEN expired or task ID missing from commit | Regenerate token; verify merge commit has `GRM-N:` prefix |
+| Post-merge can't find Vikunja task | Task not in project 6 or identifier mismatch | Verify task exists in Vikunja project 6 with correct identifier |
+| `make pytest-cov` fails | Coverage below 100% | Add tests for new code paths |
+| `scripts/configure_repo.py` fails | REPO_TOKEN missing or invalid | Set token with repo admin scope and re-run |
+| `configure_repo.py` sets wrong status checks | Stale `BRANCH_PROTECTION_CONFIG` | Updated to include `(pull_request)` suffix; re-run `configure_repo.py` |
+| Token visible in `ps aux` during install | Old version passed tokens via command line | Fixed: tokens now passed via temp file with `0600` permissions |
+| `remove-runner.yml` leaves lingering enabled | Old version didn't disable lingering | Fixed: now runs `loginctl disable-linger` and removes subuid/subgid |
+| apt cache update always reports `changed` | `cache_valid_time: 0` forced update every run | Fixed: changed to `cache_valid_time: 3600` |
+| Prune/service templates created even when `docker_rootless_setup: false` | Template tasks not guarded | Fixed: template creation now guarded by `docker_rootless_setup` |

+# GRM — Gitea Runner Manager
+
+A lean command-line tool to automate the installation, configuration, and lifecycle management of Gitea Actions runners on Arch Linux, Ubuntu, and Debian hosts.

+1. **Python CLI** (`src/gitea_runner_manager/`) — built with Click, handles argument parsing, environment loading, i18n translations, and delegates to Ansible via the `ansible-playbook` subprocess.
+2. **Ansible Role** (`ansible/roles/gitea-runner/`) — idempotent role that creates a dedicated system user, sets up rootless Docker, installs the runner binary, creates a systemd user service, and registers the runner with Gitea.
+
+## Component Tree
+
+```
+grm install <host>
+  └── RunnerManager.install()
+      └── ansible-playbook ansible/install-runner.yml
+          └── role: gitea-runner
+              ├── user_setup.yml       (create per-runner system user + lingering)
+              ├── rootless_docker.yml  (rootless Docker setup under runner user)
+              ├── install_runner.yml   (download binary, config, register, service)
+              ├── prune.yml            (Docker prune timer)
+              └── integration_test.yml (validate service is active)
+```
+
+The Ansible role task execution order (from `AGENTS.md`):
+
+```
+main.yml → systemd_check → user_setup → rootless_docker → install_runner → prune → integration_test
+```
+
+- `install_runner.yml` handles: download, config, validate, register, service
+- `main.yml` handles: prune, integration_test (NOT install_runner — avoids duplicates)
+- `systemctl --user` tasks must be guarded by `docker_rootless_setup`
+- Template creation tasks are NOT guarded by `docker_rootless_setup` (they just create files)
+
+## Per-Runner Isolation
+
+Each runner runs as a systemd user service under a dedicated system user (`grm-<name>`). Each instance has fully isolated resources:
+
+- **User**: `grm-<name>` (dedicated system user with lingering enabled)
+- **Home**: `/home/grm-<name>/`
+- **Data**: `/var/lib/gitea-runner/<name>/`
+- **Config**: `/etc/gitea-runner/<name>/`
+- **Service**: `gitea-runner.service` (systemd user service)
+- **Docker socket**: `/run/user/<UID>/docker.sock` (rootless, per-runner)

+## Additional Components
+
+From `AGENTS.md`, the project also includes:
+
+- **CI Scripts** (`scripts/`) — Automation for auto-merge, post-merge, release, publishing, molecule distribution, PR reviews, failure notifications
+- **Versioning** (`cliff.toml`) — git-cliff configuration for automated semver versioning from conventional commits
+
+## Python Modules
+
+The Python CLI layer (`src/gitea_runner_manager/`) consists of the following modules:
+
+| Module | Description |
+|--------|-------------|
+| `cli.py` | Click-based CLI entry point — defines all commands (install, update, start, stop, enable, disable, status, remove, list) |
+| `runner_manager.py` | Ansible orchestration + registry integration — delegates to executor and manages runner lifecycle |
+| `executor.py` | Ansible subprocess execution — runs `ansible-playbook` with extra-vars via temp JSON files |
+| `registry.py` | Local JSON runner registry at `~/.local/share/grm/runners.json` — stores connection metadata |
+| `i18n.py` | Internationalization translations (en, bg, de, ru, zh) |
+| `exceptions.py` | Custom exceptions (`GRMError`, `APIError`) |
+| `api_clients.py` | Gitea and Vikunja API client classes for CI automation scripts |
+| `config.py` | Configuration constants (API URLs, repo owner/name, project IDs) — overridable via environment variables |

+# CI/CD Workflow
+
+Every change to master goes through a mandatory PR workflow. No exceptions.
+
+## PR Workflow
+
+### 1. Create Vikunja Task
+
+Create a task in Vikunja project 6 to get a `GRM-N` identifier.
+
+### 2. Create Branch
+
+```bash
+git checkout master && git pull
+git checkout -b GRM-N-short-description
+```
+
+### 3. Implement Changes
+
+- Write code following conventions
+- Write/update tests (100% coverage required)
+- Update documentation (CHANGELOG, README, AGENTS.md as needed)
+
+### 4. Commit (Conventional Commits)
+
+Branch commits use conventional commit format (no `GRM-N:` prefix):
+
+```
+feat: add new feature
+fix: resolve bug
+docs: update README
+```
+
+### 5. Push and Create PR
+
+- **PR title format**: `GRM-N: <vikunja task title>` (must match the Vikunja task title exactly)
+- PR body: summary of changes, `Closes GRM-N`
+- Add `ready-to-merge` label **only after review is complete**
+
+### 6. Review the PR (Mandatory — Before Adding ready-to-merge Label)
+
+Review the full diff (`git diff master...HEAD`) focusing on:
+
+- **Functional completeness**: Does the code do what it claims? Are all requirements met?
+- **Edge cases**: Are boundary conditions, empty inputs, error paths handled?
+- **Technical excellence**:
+  - Architecture compliance and evolution
+  - Single Responsibility Principle (SRP)
+  - Deduplication (no copy-paste, single source of truth)
+  - Code smells detection and removal
+  - Best industry practices
+  - Industry-grade code quality
+  - Reusability
+  - Clean code
+  - Readability
+  - Maintainability
+  - Extensibility
+- **Performance**: No unnecessary allocations, O(n) vs O(n²), efficient data structures
+- **Security**: No secrets in logs/process list, input validation, no injection vectors
+- **User experience**: Clear error messages, intuitive CLI flags, helpful output
+- **Documentation**: Completeness and relevance of docs, CHANGELOG entries, AGENTS.md updates
+
+Post review comments using `scripts/ci/review_pr.py`:
+
+```bash
+REPO_TOKEN=<token> python3 scripts/ci/review_pr.py <pr_number> <owner/repo> \
+  --event REQUEST_CHANGES \
+  --body "Review summary" \
+  --comments-json comments.json
+```
+
+### 7. Address Review Comments
+
+Fix each comment one by one, commit, and push. Re-review until satisfied.
+
+### 8. Approve and Merge
+
+Once all comments are addressed:
+
+```bash
+REPO_TOKEN=<token> python3 scripts/ci/review_pr.py <pr_number> <owner/repo> \
+  --event APPROVE \
+  --body "All comments addressed. LGTM."
+```
+
+Then add the `ready-to-merge` label. The auto-merge workflow will:
+
+1. **Validate** PR title format and match against Vikunja task title
+2. **Check** that at least one APPROVE review exists
+3. Wait for all CI checks to pass
+4. Squash-merge with title: `GRM-N <conventional commit message>` (space-separated)
+5. The post-merge workflow marks the Vikunja task as done
+6. The release workflow automatically versions, tags, and publishes
+
+### 9. Post-Merge Automation
+
+After the squash-merge:
+
+- The **post-merge workflow** (`.gitea/workflows/post-merge.yml`) triggers on push to `master` and runs `scripts/ci/post_merge.py` to mark the Vikunja task as done, extracting the task ID from the merge commit message.
+- The **release workflow** (`.gitea/workflows/release.yml`) triggers on push to `master` and automatically versions, tags, and publishes (see below).
+
+## Branch Protection (Required Gitea Settings)
+
+Configure the following branch protection rules for `master` in Gitea repo settings:
+
+- **Require pull request**: No direct pushes to master
+- **Require approval review**: At least 1 `APPROVE` review before merge
+- **Require status checks**: CI quality + molecule tests must pass
+- **Block force pushes**: No history rewriting on master
+
+The auto-merge workflow enforces the APPROVE review check programmatically as a defense-in-depth measure, but branch protection is the primary gate.
+
+## CI Path Filtering
+
+The CI workflow (`.gitea/workflows/ci.yml`) includes a `detect-changes` job that checks whether any files under `ansible/` or `.ansible-lint` have changed. If no Ansible files are changed, molecule tests are skipped — this prevents non-Ansible changes (e.g., Python scripts, workflow YAML, docs) from being blocked by molecule test infrastructure flakiness.
+
+The `detect-changes` job:
+
+- For pull requests: compares `origin/master` against the PR head SHA
+- For pushes to master: compares `HEAD~1` against `HEAD`
+- Outputs `ansible-changed` as `true` or `false`
+
+The `molecule-tests` job depends on both `quality` and `detect-changes`, and only runs if `ansible-changed == 'true'`.
+
+CI triggers only on `opened` and `synchronize` PR events (not `labeled`).
+
+## CI Quality Job
+
+The `quality` job in `.gitea/workflows/ci.yml` runs:
+
+1. `make setup` — full environment setup
+2. `make lint-all` — ruff + pyright + bandit + ansible-lint + checkmake
+3. `make pytest-cov` — unit tests with 100% coverage enforcement
+4. `python3 scripts/check_test_speed.py --max-seconds 10` — verify unit tests run fast
+5. `PYTHONPATH=src python3 scripts/ci/release.py --dry-run` — release dry-run validation
+
+## Automated Release Pipeline
+
+After a PR is merged to master, the release pipeline runs automatically.
+
+### Release Workflow (`.gitea/workflows/release.yml`)
+
+- Triggers on push to `master`
+- Sets up full dev environment (`make setup`) so lint and tests can run
+- Installs git-cliff (version 2.13.0)
+- Configures git as `grm-ci-bot`
+- Runs `scripts/ci/release.py` which uses **git-cliff** to:
+  - Calculate the next semver version from conventional commits since the last tag
+  - Update `__version__` in `src/gitea_runner_manager/__init__.py` (single source of truth)
+  - Update `CHANGELOG.md` with the new version section
+  - **Run `make lint-ruff` and `make pytest-cov`** to verify the release is healthy
+  - If lint or tests fail, **abort immediately** — no commit, no tag
+  - Commit with `release: vX.Y.Z` prefix (cleaner than `chore(release):`)
+  - Create an annotated tag `vX.Y.Z` on the release commit
+  - Push both the commit and tag to master
+- `--skip-tests` flag bypasses test verification (emergency use only, not recommended)
+- Loops are prevented by `has_unreleased_changes` — after a release commit is tagged, the next run finds no unreleased changes and exits
+- On failure, creates a Gitea issue via `scripts/ci/notify_failure.py`
+
+### Publish Workflow (`.gitea/workflows/publish.yml`)
+
+- Triggers on tag push (`v*`)
+- Installs git-cliff (version 2.13.0)
+- Installs build tools (`build`, `twine`, `requests`, `python-dotenv`, `click`)
+- Validates `PYPI_TOKEN` is set (warns if missing)
+- Builds the Python package
+- Optionally publishes to PyPI (if `PYPI_TOKEN` is set)
+- Creates a Gitea release with git-cliff-generated release notes
+- Uses `scripts/ci/publish.py` for build and publish orchestration
+- On failure, creates a Gitea issue via `scripts/ci/notify_failure.py`
+
+### Auto-Merge Workflow (`.gitea/workflows/auto-merge.yml`)
+
+- Triggers on `pull_request` labeled events
+- Runs `scripts/ci/auto_merge.py` with the branch name, PR title, repository, PR number, and label name
+- Validates PR title format, checks for APPROVE review, waits for CI, and squash-merges
+
+### Post-Merge Workflow (`.gitea/workflows/post-merge.yml`)
+
+- Triggers on push to `master`
+- Runs `scripts/ci/post_merge.py` with the latest commit message and commit SHA
+- Marks the corresponding Vikunja task as done
+
+### Smart CI: User-Facing vs Workflow-Only Changes
+
+Not all changes require the full CI pipeline or a new release. The project uses
+`scripts/ci/classify_changes.py` to classify changed files into two categories:
+
+**User-facing paths** (tool changes → release needed):
+- `src/gitea_runner_manager/**` — Python CLI source
+- `ansible/**` — Ansible role
+- `pyproject.toml` — Package metadata
+
+**Workflow-only paths** (infrastructure → no release needed):
+- `.gitea/workflows/**`, `scripts/**`, `docs/**`, `tests/**`
+- `AGENTS.md`, `README.md`, `CHANGELOG.md`, `Makefile`, `cliff.toml`, etc.
+
+**CI behavior based on classification:**
+- **Molecule tests**: Only run when `ansible/` or `.ansible-lint` files change
+- **Release dry-run**: Only runs when user-facing files change (separate `release-dry-run` job)
+- **Quality job** (lint, unit tests, coverage, doc-coverage): Always runs
+- **Release workflow**: `release.py` calls `classify_changes.py` to check if any
+  user-facing files changed since the last tag. If not, the release is skipped
+  entirely — no version bump, no tag, no publish.
+
+### Dynamic Runner Discovery
+
+Molecule tests are distributed across available Gitea Actions runners
+dynamically. The `discover-runners` job runs `scripts/ci/discover_runners.py` which queries the Gitea API for
+registered runners at three levels (repo, org, instance) and generates
+a matrix of runner indices. If the API query fails (e.g., no admin
+access for instance-level runners), it falls back to the
+`MOLECULE_RUNNERS` repo variable, then to a default of 3.
+
+The `molecule-tests` job uses `fromJSON()` to consume the dynamic
+matrix, and passes the runner count to `distribute_molecule.py
+--max-runners` so test pairs are evenly distributed.
+
+When adding or removing Gitea runners:
+1. If runners are registered at the repo/org level, they're auto-detected
+2. If runners are at the instance level, update the `MOLECULE_RUNNERS` repo variable
+3. The workflow automatically scales the matrix to match available runners
+
+## git-cliff Commit Preprocessing
+
+Merge commits on master have the format `GRM-N <conventional commit>`. The `GRM-N ` prefix is not a valid conventional commit prefix, so `cliff.toml` includes a `commit_preprocessors` entry that strips it before parsing:
+
+```toml
+commit_preprocessors = [
+    # Strip GRM-N task ID prefix from merge commits so git-cliff sees conventional commits
+    { pattern = "^GRM-\\d+\\s+", replace = "" },
+]
+```
+
+This ensures all merged work appears in the changelog.
+
+### git-cliff Configuration Highlights (`cliff.toml`)
+
+- `conventional_commits = true` — parse conventional commit format
+- `filter_unconventional = true` — skip non-conventional commits
+- `render_always = true` — always render the changelog
+- `trim = true` — trim whitespace
+- Commit parsers group commits into: Features, Bug Fixes, Documentation, Performance, Refactor, Styling, Testing, Miscellaneous Tasks, Security, Revert, Other
+- `chore(release): prepare for`, `chore(deps.*)`, `chore(pr)`, `chore(pull)` commits are skipped
+- `sort_commits = "oldest"` — oldest commits first
+
+## Version Bumping Rules (git-cliff)
+
+| Commit type | Version bump |
+|-------------|-------------|
+| `feat:` | minor (0.X.0) |
+| `fix:` | patch (0.0.X) |
+| `feat!:` or `BREAKING CHANGE` | minor (pre-1.0: major would be 1.0.0) |
+| `chore:`, `ci:`, `docs:` | no bump (excluded by cliff.toml) |
+
+From `cliff.toml` `[bump]` section:
+
+- `features_always_bump_minor = true`
+- `breaking_always_bump_major = false`
+- `initial_tag = "0.1.0"`
+
+The version source is `__version__` in `src/gitea_runner_manager/__init__.py`, read by setuptools via `dynamic = ["version"]` in `pyproject.toml`. The release script only updates `__init__.py` — no need to touch `pyproject.toml`. `grm --version` reports this version.
+
+## Title Format Summary
+
+| What | Format | Example |
+|------|--------|---------|
+| Branch name | `GRM-N-short-description` | `GRM-33-add-pr-review-step` |
+| Branch commits | `<conventional commit>` | `feat: add review script` |
+| PR title | `GRM-N: <vikunja task title>` | `GRM-33: Add mandatory PR review step` |
+| Merge commit | `GRM-N <conventional commit>` | `GRM-33 feat: add review script` |

+## Key Conventions
+
+- Python 3.12+ required (ruff/pyright target `py312`)
+- 100% test coverage required (`--cov-fail-under=100`)
+- Conventional commits on feature branches (no `GRM-N:` prefix)
+- Branch names must include `GRM-N` task ID
+- Line length: 120 chars
+- Secrets are passed via temp JSON files, never on the command line (CWE-214)

+
+## Code Style Rules
+
+- **Python version**: 3.12+ (ruff and pyright target `py312`)
+- **Line length**: 120 characters
+- **Test coverage**: 100% required (`--cov-fail-under=100`)
+- **Secrets handling**: Secrets are passed via temp JSON files with `0600` permissions, never on the command line (CWE-214). Extra-vars are written to a temporary JSON file and passed via `--extra-vars @tempfile`, which is deleted after execution. This prevents secrets from being visible in the process list (`ps aux`).
+- **Linting**: `make lint-all` runs ruff + pyright + bandit + ansible-lint + checkmake

+## PR Workflow Summary
+
+Every change to master goes through this workflow. No exceptions.
+
+1. **Create Vikunja task** — get a `GRM-N` identifier (Vikunja project 6)
+2. **Create branch** — `GRM-N-short-description`
+3. **Implement** — write code, tests (100% coverage), update docs
+4. **Commit** — conventional commits (no `GRM-N:` prefix on branch)
+5. **Push & create PR** — title: `GRM-N: <vikunja task title>`, body: summary + `Closes GRM-N`
+6. **Review** — review the full diff focusing on: functional completeness, edge cases, technical excellence (architecture, SRP, deduplication, code smells, best practices, code quality, reusability, clean code, readability, maintainability, extensibility), performance, security, UX, documentation completeness/relevance. Post review comments via `scripts/review_pr.py`.
+7. **Address comments** — fix each comment, commit, push, re-review
+8. **Approve** — post an `APPROVE` review via `scripts/review_pr.py`
+9. **Add `ready-to-merge` label** — auto-merge workflow squash-merges with title `GRM-N <conventional commit message>`, post-merge workflow marks the Vikunja task as done, release workflow automatically versions and tags
+
+### Branch Protection (Required Gitea Settings)
+
+Configure the following branch protection rules for `master` in Gitea repo settings:
+
+- **Require pull request**: No direct pushes to master
+- **Require approval review**: At least 1 `APPROVE` review before merge
+- **Require status checks**: CI quality + molecule tests must pass
+- **Block force pushes**: No history rewriting on master
+
+The auto-merge workflow enforces the APPROVE review check programmatically as a defense-in-depth measure, but branch protection is the primary gate.
+
+## Build & Test Commands
+
+```bash
+make setup          # Create venv, install deps, set up hooks
+make lint-all       # ruff + pyright + bandit + ansible-lint + checkmake
+make pytest-cov     # Unit tests with 100% coverage enforcement
+make test-unit      # Unit tests without coverage
+make molecule       # All 6 scenarios on Ubuntu 22.04
+make molecule-all   # All 6 scenarios on all 4 supported OSes
+make test-all       # pytest-cov + molecule
+```
+
+## Ansible Role Conventions
+
+```
+main.yml → systemd_check → user_setup → rootless_docker → install_runner → prune → integration_test
+```
+
+- `install_runner.yml` handles: download, config, validate, register, service
+- `main.yml` handles: prune, integration_test (NOT install_runner — avoids duplicates)
+- `systemctl --user` tasks must be guarded by `docker_rootless_setup`
+- Template creation tasks are NOT guarded by `docker_rootless_setup` (they just create files)
+
+## Known Issues
+
+- `ansible-lint` may warn about `command-instead-of-module` for `systemctl --user` calls — this is expected (systemd module doesn't support user services) and skipped in `.ansible-lint`
+- Molecule Docker driver may print "Event loop is closed" warnings on interrupt — harmless

+# Decision Log
+
+Key technical decisions for the GRM project, extracted from `CHANGELOG.md` and `AGENTS.md`.
+
+---
+
+## ADR-001: Dynamic Versioning via `__init__.py`
+
+**Date:** 2026-06-21 (v0.2.0 unreleased)
+
+**Decision:** Use `dynamic = ["version"]` in `pyproject.toml` with setuptools `attr` to source the version from `__version__` in `src/gitea_runner_manager/__init__.py`.
+
+**Rationale:** `__init__.py` is the single source of truth for the version. The release script (`scripts/release.py`) only updates `__init__.py` — there is no need to touch `pyproject.toml`. `grm --version` reports this version directly. This eliminates version duplication across files and ensures the runtime version always matches the tagged release.
+
+**Source:** `CHANGELOG.md` (Unreleased — Added), `AGENTS.md` (Version Bumping Rules)
+
+---
+
+## ADR-002: Rootless Docker per Runner
+
+**Date:** Project inception (documented in README Architecture)
+
+**Decision:** Each runner instance runs in an isolated rootless Docker environment under a dedicated system user (`grm-<name>`), with its own Docker socket at `/run/user/<UID>/docker.sock`.
+
+**Rationale:** Rootless Docker per-runner avoids conflicts with the host's Docker installation and enables true parallel execution of multiple runners on the same host. Each instance has fully isolated resources: user, home, data directory, config directory, systemd user service, and Docker socket. This is a core feature of GRM — enabling multiple isolated runners on the same host.
+
+**Source:** `README.md` (Architecture, Features), `AGENTS.md` (Architecture)
+
+---
+
+## ADR-003: Conventional Commits + git-cliff for Automated Versioning
+
+**Date:** 2026-06-21 (v0.2.0 unreleased)
+
+**Decision:** Use conventional commits on feature branches and git-cliff (`cliff.toml`) to calculate the next semver version from commit history, generate the changelog, and automate releases.
+
+**Rationale:** `scripts/release.py` uses git-cliff to calculate the next version from conventional commits since the last tag. Merge commits on master have the format `GRM-N <conventional commit>`, so `cliff.toml` includes a `commit_preprocessors` entry that strips the `GRM-N ` prefix before parsing. Version bumping rules: `feat:` → minor, `fix:` → patch, `feat!:`/`BREAKING CHANGE` → minor (pre-1.0), `chore:`/`ci:`/`docs:` → no bump. This fully automates versioning and changelog generation.
+
+**Source:** `CHANGELOG.md` (Unreleased — Added), `AGENTS.md` (Automated Release Pipeline, git-cliff Commit Preprocessing, Version Bumping Rules), `cliff.toml`
+
+---
+
+## ADR-004: Enforce Tests Pass Before Tagging a Release
+
+**Date:** 2026-06-21 (v0.2.2)
+
+**Decision:** The release workflow runs `make lint-ruff` and `make pytest-cov` before creating a release commit or tag. If lint or tests fail, the release aborts immediately — no commit, no tag.
+
+**Rationale:** This ensures every tagged release is healthy. A `--skip-tests` flag exists for emergency use only but is not recommended. This decision was made as a bug fix after identifying that releases could be tagged without verifying test health. Loops are prevented by `has_unreleased_changes` — after a release commit is tagged, the next run finds no unreleased changes and exits.
+
+**Source:** `CHANGELOG.md` (0.2.2 — Bug Fixes: "Enforce tests pass before tagging a release"), `AGENTS.md` (Automated Release Pipeline)
+
+---
+
+## ADR-005: Branch Protection + Auto-Merge Workflow
+
+**Date:** 2026-06-21 (v0.2.0 unreleased)
+
+**Decision:** Require branch protection on `master` (require pull request, require approval review, require status checks, block force pushes) and use an auto-merge workflow that programmatically enforces the APPROVE review check.
+
+**Rationale:** Branch protection is the primary gate — no direct pushes to master, at least 1 APPROVE review before merge, CI quality + molecule tests must pass, and no history rewriting. The auto-merge workflow (`scripts/auto_merge.py`) enforces the APPROVE review check programmatically as a defense-in-depth measure. When the `ready-to-merge` label is added, the workflow validates PR title format, checks for APPROVE review, waits for CI, and squash-merges with title `GRM-N <conventional commit message>`. The post-merge workflow then marks the Vikunja task as done.

+## ADR-006: Path-Based CI Filtering for Molecule Tests
+
+**Date:** 2026-06-21 (v0.2.0 unreleased)
+
+**Decision:** The CI workflow includes a `detect-changes` job that checks whether any files under `ansible/` or `.ansible-lint` have changed. If no Ansible files are changed, molecule tests are skipped.
+
+**Rationale:** This prevents non-Ansible changes (e.g., Python scripts, workflow YAML, docs) from being blocked by molecule test infrastructure flakiness. Molecule tests are only relevant when Ansible files change. The `molecule-tests` job depends on both `quality` and `detect-changes`, and only runs if `ansible-changed == 'true'`. CI triggers only on `opened` and `synchronize` PR events (not `labeled`) to avoid redundant runs.

+
+## Setup Development Environment
+
+```bash
+make setup        # Creates venv, installs deps, sets up hooks
+source .venv/bin/activate
+```
+
+The `make setup` target (from the `Makefile`):
+
+- Verifies Python 3.12+ is installed
+- Creates a virtualenv in `.venv`
+- Installs/updates `pip`, `setuptools`, and `wheel`
+- Creates `.env` from `.env.example` if not present
+- Generates shell activation scripts (`activate.sh`, `activate.fish`, `activate.zsh`)
+- Installs `checkmake` via `scripts/install_checkmake.py`
+- Runs `scripts/setup.sh` to install dependencies and hooks
+
+### Developer Quick Start
+
+```bash
+git clone https://git.oblachno.oblachno.com/oblachno/gitea-runner-manager.git
+cd gitea-runner-manager
+pyenv install 3.12
+pyenv local 3.12
+make setup
+```
+
+### Configure Gitea Credentials
+
+```bash
+cp .env.example .env
+# Edit .env:
+# GITEA_URL=https://git.example.com
+# GITEA_REGISTRATION_TOKEN=your-registration-token
+```
+
+`GITEA_REGISTRATION_TOKEN` is the runner registration token obtained from your Gitea instance (Admin → Actions → Runners → Create Registration Token).
+
+#### Admin API Token (optional)
+
+Set `GITEA_ADMIN_TOKEN` to enable informational API checks during integration test. This is **optional** — the test primarily verifies the runner by checking:
+
+1. **`.runner` registration file** exists and contains valid JSON (proves successful registration)
+2. **Systemd user service** is active (proves daemon is polling for jobs)
+
+API checks, if enabled, are purely informational and do not affect pass/fail.
+
+## Running Linters
+
+```bash
+make lint          # Python (ruff + pyright + bandit)
+make lint-bandit   # Security scan only
+make ansible-lint  # Ansible
+make makefile-lint # Makefile
+```
+
+The full lint target (`make lint-all`) runs all of the above:
+
+```bash
+make lint-all       # ruff + pyright + bandit + ansible-lint + checkmake
+```
+
+Individual lint targets from the `Makefile`:
+
+| Target | Description |
+|--------|-------------|
+| `lint-ruff` | `ruff check src/ tests/` |
+| `lint-format` | `ruff format --check src/ tests/` |
+| `typecheck` | `pyright` |
+| `lint-bandit` | `bandit -r src/ scripts/` |
+| `ansible-lint` | `ansible-lint ansible/` |
+| `makefile-lint` | `checkmake Makefile` |
+| `lint` | ruff + format check + pyright + bandit |
+| `lint-all` | lint + ansible-lint + makefile-lint |

+# Testing Strategy
+
+## Unit Tests
+
+```bash
+make test-unit
+```
+
+Runs pytest with 100% coverage requirement.
+
+From the `Makefile`:
+
+- `test-unit` — `pytest tests/unit/ -v --no-cov` (unit tests without coverage)
+- `pytest-cov` — `pytest tests/unit/ -v --cov=src/gitea_runner_manager --cov=scripts --cov-report=term-missing --cov-fail-under=100` (unit tests with 100% coverage enforcement)
+
+The coverage requirement is `--cov-fail-under=100` — 100% test coverage is required.
+
+## Molecule Tests
+
+```bash
+make molecule      # Quick: all 6 scenarios on Ubuntu 22.04
+make molecule-all  # Full: all 6 scenarios on all 4 supported OSes
+```
+
+Runs six scenarios:
+
+- **default** — Rootless Docker runner installation
+- **multi-instance** — Two isolated runner instances on the same host
+- **lifecycle** — Stop, disable, re-enable, and start sequence
+- **template-content** — Verify rendered systemd user service and prune templates
+- **deregister** — Runner deregistration
+- **update** — Runner binary update
+
+All scenarios test idempotence (second run produces zero changes).
+
+### Platforms
+
+4 platforms are tested: `ubuntu-2204`, `ubuntu-2404`, `debian-12`, `archlinux`.
+
+The platform list is defined in `scripts/distribute_molecule.py` (single source of truth).
+
+### CI Test Distribution
+
+CI runs all 6 scenarios × 4 platforms (24 test pairs) distributed across 3 parallel runners.
+
+From `.gitea/workflows/ci.yml`, the `molecule-tests` job uses a matrix of `runner-index: [0, 1, 2]` and calls `scripts/distribute_molecule.py --runner-index <index> --max-runners 3` to discover assigned test pairs, then runs `scripts/molecule_ci_guard.py` with those pairs.
+
+## Integration Tests
+
+```bash
+make test-integration
+```
+
+Tests the full CLI lifecycle commands end-to-end (mocked executor boundary).
+
+From the `Makefile`:
+
+- `test-integration` — `pytest tests/integration/ -v --no-cov`
+
+## Full Test Suite
+
+```bash
+make test-all      # Runs unit tests + linters + molecule
+```
+
+From the `Makefile`:
+
+- `test-all` — `pytest-cov + molecule` (unit tests with coverage + all 6 molecule scenarios on Ubuntu 22.04)
+
+## Build & Test Commands Summary
+
+From `AGENTS.md`:
+
+```bash
+make setup          # Create venv, install deps, set up hooks
+make lint-all       # ruff + pyright + bandit + ansible-lint + checkmake
+make pytest-cov     # Unit tests with 100% coverage enforcement
+make test-unit      # Unit tests without coverage
+make molecule       # All 6 scenarios on Ubuntu 22.04
+make molecule-all   # All 6 scenarios on all 4 supported OSes
+make test-all       # pytest-cov + molecule
+```
+
+## Known Issues
+
+- `ansible-lint` may warn about `command-instead-of-module` for `systemctl --user` calls — this is expected (systemd module doesn't support user services) and skipped in `.ansible-lint`
+- Molecule Docker driver may print "Event loop is closed" warnings on interrupt — harmless

+# FAQ
+
+### How do I obtain the Gitea registration token?
+
+The runner registration token is obtained from your Gitea instance: **Admin → Actions → Runners → Create Registration Token**. Set it as `GITEA_REGISTRATION_TOKEN` in your `.env` file or pass it via `--token` on the command line.
+
+### How do I skip the sudo password prompt for automation?
+
+Configure passwordless sudo on the remote host and pass `--no-ask-become-pass` to the CLI command. This is recommended for CI/CD pipelines.
+
+### Can I run multiple runners on the same host?
+
+Yes. Each runner instance is fully isolated with its own system user (`grm-<name>`), rootless Docker daemon, data directory, and systemd user service. Install additional runners with different `--name` values and manage them independently by name.
+
+### Why does my runner appear offline after installation?
+
+Check that `GITEA_URL` and `GITEA_REGISTRATION_TOKEN` are correct, verify the runner service is running with `sudo -u grm-<name> systemctl --user status gitea-runner`, and check the logs for registration errors. You can also confirm the runner appears as **Online** in the Gitea UI under **Actions → Runners**.
+
+### What does the "Event loop is closed" warning mean?
+
+This is a harmless cleanup traceback from Molecule's Docker driver when the test process is interrupted. It does not indicate a test failure.
+
+### Where are runner connection details stored?
+
+GRM stores each runner's connection details (host, user, SSH key, Gitea URL) in a local JSON registry at `~/.local/share/grm/runners.json`. After installation, lifecycle commands work by runner name only — you can override any stored value by passing the corresponding flag.

+# Getting Started
+
+## Developer Setup
+
+```bash
+git clone https://git.oblachno.oblachno.com/oblachno/gitea-runner-manager.git
+cd gitea-runner-manager
+pyenv install 3.12
+pyenv local 3.12
+make setup
+```
+
+## Configure Gitea Credentials
+
+```bash
+cp .env.example .env
+# Edit .env:
+# GITEA_URL=https://git.example.com
+# GITEA_REGISTRATION_TOKEN=your-registration-token
+```
+
+`GITEA_REGISTRATION_TOKEN` is the runner registration token obtained from your Gitea instance (Admin → Actions → Runners → Create Registration Token).
+
+### Admin API Token (optional)
+
+Set `GITEA_ADMIN_TOKEN` to enable informational API checks during integration test. This is **optional** — the test primarily verifies the runner by checking:
+
+1. **`.runner` registration file** exists and contains valid JSON (proves successful registration)
+2. **Systemd user service** is active (proves daemon is polling for jobs)
+
+API checks, if enabled, are purely informational and do not affect pass/fail.
+
+## Install a Runner
+
+Using the CLI (you will be prompted for the sudo password by default):
+
+```bash
+grm install 192.168.1.10 --user ubuntu --key ~/.ssh/id_ed25519 --name prod-runner
+```
+
+> **Automation tip:** Configure passwordless sudo on the remote host and pass `--no-ask-become-pass` to skip the password prompt. This is recommended for CI/CD pipelines.
+
+Using Make:
+
+```bash
+make install HOST=192.168.1.10 USER=ubuntu KEY=~/.ssh/id_ed25519 NAME=prod-runner
+```
+
+## Verify Runner
+
+The installer performs an automated integration test that verifies:
+
+1. **`.runner` file exists** with valid JSON containing `id`, `uuid`, `token`, `address` — this proves successful registration with Gitea
+2. **Systemd user service is active** — this proves the daemon is polling for jobs
+
+You can also check the Gitea UI under **Actions → Runners** to confirm the runner appears as **Online**.
+
+Optional: If `GITEA_ADMIN_TOKEN` is set, the installer will also query the Gitea API and report whether the runner appears in the admin or repo runners list. This is purely informational.
+
+## View Logs
+
+**GRM application logs** (Python CLI output):
+
+```bash
+# Application log file (all messages including DEBUG)
+cat ~/.local/state/grm/logs/grm.log
+
+# Enable debug logging in the current session
+GRM_LOG_LEVEL=DEBUG grm install 192.168.1.10 --user ubuntu --name prod-runner
+```
+
+**Runner logs** (on the remote host):
+
+```bash
+# Runner logs (via systemd user service)
+sudo -u grm-<name> journalctl --user -u gitea-runner -f
+```
+
+The GRM application writes to two destinations:
+
+| Destination | Level | Content |
+|-------------|-------|---------|
+| Console (stdout) | `GRM_LOG_LEVEL` (default: INFO) | Colorised user-facing messages and operation reports |
+| `~/.local/state/grm/logs/grm.log` | DEBUG | All messages with timestamps and severity |
+
+Set `GRM_LOG_LEVEL` to one of `DEBUG`, `INFO`, `WARNING`, `ERROR`, or `CRITICAL` to control console verbosity. The log file always captures everything at DEBUG level regardless of the console setting.
+
+Console output is automatically colorised via ``click.echo``: operation headers in bright cyan, completed steps in green, failures in red, and status updates in yellow.

+# Installation
+
+## Prerequisites
+
+- **SSH key authentication** — The remote host must be reachable via SSH using the user specified with `--user` and the private key specified with `--key`. GRM uses Ansible under the hood, which connects to the target host over SSH to execute all installation and configuration tasks. Without valid SSH credentials, Ansible cannot establish a connection and the deployment will fail.
+- **Sudo access** — GRM requires root privileges on the remote host to create system users, install packages, and configure rootless Docker. By default, you will be prompted interactively for the sudo password. For automation or uninterrupted workflows, configure passwordless sudo on the remote host and pass `--no-ask-become-pass`.
+
+## Supported Operating Systems
+
+- Arch Linux
+- Ubuntu 22.04 / 24.04
+- Debian 12
+
+All supported OSes are tested in CI via molecule scenarios on every PR.
+
+## Quick Start Install
+
+Using the CLI (you will be prompted for the sudo password by default):
+
+```bash
+grm install 192.168.1.10 --user ubuntu --key ~/.ssh/id_ed25519 --name prod-runner
+```
+
+> **Automation tip:** Configure passwordless sudo on the remote host and pass `--no-ask-become-pass` to skip the password prompt. This is recommended for CI/CD pipelines.
+
+## Make Install
+
+Using Make:
+
+```bash
+make install HOST=192.168.1.10 USER=ubuntu KEY=~/.ssh/id_ed25519 NAME=prod-runner
+```
+
+## Runner Registry
+
+After installation, GRM stores each runner's connection details (host, user, SSH key, Gitea URL) in a local JSON registry at `~/.local/share/grm/runners.json`. This means you rarely need to repeat connection arguments:
+
+```bash
+# List all registered runners with live systemd status
+grm list
+```
+
+## Multiple Instances on the Same Host
+
+Each runner instance is fully isolated with its own system user, rootless Docker daemon, data directory, and systemd user service:
+
+```bash
+# Install two runners on the same host
+grm install 192.168.1.10 --user ubuntu --name workflow-runner
+grm install 192.168.1.10 --user ubuntu --name build-runner
+
+# Manage them independently by name
+grm stop workflow-runner
+grm status build-runner

+# Troubleshooting
+
+## "Event loop is closed" warning
+
+This is a harmless cleanup traceback from Molecule's Docker driver when the test process is interrupted. It does not indicate a test failure.
+
+## Runner appears offline after installation
+
+- Check that the `GITEA_URL` and `GITEA_REGISTRATION_TOKEN` environment variables are correct.
+- Verify the runner service is running: `sudo -u grm-<name> systemctl --user status gitea-runner`.
+- Check logs for registration errors.
+
+## Integration test fails
+
+The test checks two things:
+
+1. **`.runner` file missing or invalid** — Registration failed. Check:
+   - `GITEA_URL` and `GITEA_REGISTRATION_TOKEN` are correct
+   - Runner logs for registration errors
+   - The `.runner` file should exist at `/var/lib/gitea-runner/<name>/.runner`

+2. **Service not running** — Daemon failed to start. Check:
+   - `sudo -u grm-<name> systemctl --user status gitea-runner`
+   - Logs for connection errors
+
+## Rootless Docker: service fails to start
+
+- Check the service status: `sudo -u grm-<name> systemctl --user status gitea-runner`.
+- Verify the rootless Docker daemon is running: `sudo -u grm-<name> systemctl --user status docker`.
+- Verify the Docker socket exists: `ls /run/user/$(id -u grm-<name>)/docker.sock`.
+- Check logs: `sudo -u grm-<name> journalctl --user -u gitea-runner -f`.
+- Ensure lingering is enabled for the runner user: `loginctl show-user grm-<name> | grep Linger`.

+## Common Issues Reference Table
+
+| Symptom | Likely Cause | Solution |
+|---------|-------------|----------|
+| Pre-commit rejects commit message | Missing conventional format or GRM-N prefix present | Use `feat: description` format without `GRM-N:` |
+| `make molecule` fails with `runner_name is undefined` | Verify playbook missing variable | Fixed in Phase 1.1; ensure you're on latest master |
+| CI molecule job fails | Docker not available on runner host | Ensure Gitea runner host has Docker installed and running |
+| Auto-merge doesn't trigger | Label not exactly `ready-to-merge` or CI checks not all green | Verify label spelling; check CI status |
+| Vikunja task not updated after merge | VIKUNJA_TOKEN expired or task ID missing from commit | Regenerate token; verify merge commit has `GRM-N:` prefix |
+| Post-merge can't find Vikunja task | Task not in project 6 or identifier mismatch | Verify task exists in Vikunja project 6 with correct identifier |
+| `make pytest-cov` fails | Coverage below 100% | Add tests for new code paths |
+| `scripts/configure_repo.py` fails | REPO_TOKEN missing or invalid | Set token with repo admin scope and re-run |
+| `configure_repo.py` sets wrong status checks | Stale `BRANCH_PROTECTION_CONFIG` | Updated to include `(pull_request)` suffix; re-run `configure_repo.py` |
+| Token visible in `ps aux` during install | Old version passed tokens via command line | Fixed: tokens now passed via temp file with `0600` permissions |
+| `remove-runner.yml` leaves lingering enabled | Old version didn't disable lingering | Fixed: now runs `loginctl disable-linger` and removes subuid/subgid |
+| apt cache update always reports `changed` | `cache_valid_time: 0` forced update every run | Fixed: changed to `cache_valid_time: 3600` |
+| Prune/service templates created even when `docker_rootless_setup: false` | Template tasks not guarded | Fixed: template creation now guarded by `docker_rootless_setup` |
