## Version Management

**`README.md` is the single source of truth for the repository version.**

- **Bump the patch version on every PR** — increment `XX.YY.ZZ` (e.g. `01.02.03` → `01.02.04`) in `README.md` before opening the PR; the `sync-version-on-merge` workflow propagates it automatically to all badges and `FILE INFORMATION` headers on merge to `main`.
- The `VERSION: XX.YY.ZZ` field in `README.md` governs all other version references.
- Version format is zero-padded semver: `XX.YY.ZZ` (e.g. `01.02.03`).
- Never hardcode a specific version in document body text — use the badge or FILE INFORMATION header only.

### Joomla Version Alignment

The version in `README.md` **must always match** the `<version>` tag in `manifest.xml` and the latest entry in `updates.xml`. The `make release` command / release workflow updates all three automatically.

```xml
<!-- In manifest.xml — must match README.md version -->
<version>01.02.04</version>

<!-- In updates.xml — prepend a new <update> block for every release.
     Note: the backslash in version="4\.[0-9]+" is a literal backslash character
     in the XML attribute value. Joomla's update server treats the value as a
     regular expression, so \. matches a literal dot. -->
<updates>
	<update>
		<name>{{EXTENSION_NAME}}</name>
		<version>01.02.04</version>
		<downloads>
			<downloadurl type="full" format="zip">
				https://git.mokoconsulting.tech/MokoConsulting/MokoCassiopeia/releases/download/01.02.04/{{EXTENSION_ELEMENT}}-01.02.04.zip
			</downloadurl>
		</downloads>
		<targetplatform name="joomla" version="4\.[0-9]+" />
	</update>
	<!-- … older entries preserved below … -->
</updates>

## updates.xml — Required in Repo Root

`updates.xml` **must exist at the repository root**. It is the Joomla update server manifest that allows Joomla installations to check for new versions of this extension.

The `manifest.xml` must reference it via:
```xml
<updateservers>
	<server type="extension" priority="1" name="{{EXTENSION_NAME}}">
		https://git.mokoconsulting.tech/MokoConsulting/MokoCassiopeia/raw/main/updates.xml
	</server>
</updateservers>
```

**Rules:**
- Every release must prepend a new `<update>` block at the top of `updates.xml` — old entries must be preserved below.
- The `<version>` in `updates.xml` must exactly match `<version>` in `manifest.xml` and the version in `README.md`.
- The `<downloadurl>` must be a publicly accessible direct download link (GitHub Releases asset URL).
- `<targetplatform name="joomla" version="4\.[0-9]+">` — the backslash is a **literal backslash character** in the XML attribute value; Joomla's update-server parser treats the value as a regular expression, so `\.` matches a literal dot and `[0-9]+` matches one or more digits. Do not double-escape it.

---

## manifest.xml Rules

- Lives at the repo root as `manifest.xml` (not inside `site/` or `admin/`).
- `<version>` tag must be kept in sync with `README.md` version and `updates.xml`.
- Must include `<updateservers>` block pointing to this repo's `updates.xml`.
- Must include `<files folder="site">` and `<administration>` sections.
- Joomla 4.x requires `<namespace path="src">Moko\{{EXTENSION_NAME}}</namespace>` for namespaced extensions.

---

## GitHub Actions — Token Usage

Every workflow must use **`secrets.GH_TOKEN`** (the org-level Personal Access Token).

```yaml
# ✅ Correct
- uses: actions/checkout@v4
  with:
    token: ${{ secrets.GH_TOKEN }}

env:
  GH_TOKEN: ${{ secrets.GH_TOKEN }}
```

```yaml
# ❌ Wrong — never use these in workflows
token: ${{ github.token }}
token: ${{ secrets.GITHUB_TOKEN }}
```

## Naming Conventions

| Context | Convention | Example |
|---------|-----------|---------|
| PHP class | `PascalCase` | `MyController` |
| PHP method / function | `camelCase` | `getItems()` |
| PHP variable | `$snake_case` | `$item_id` |
| PHP constant | `UPPER_SNAKE_CASE` | `MAX_ITEMS` |
| PHP class file | `PascalCase.php` | `ItemModel.php` |
| YAML workflow | `kebab-case.yml` | `ci-joomla.yml` |
| Markdown doc | `kebab-case.md` | `installation-guide.md` |

---

## Commit Messages

Format: `<type>(<scope>): <subject>` — imperative, lower-case subject, no trailing period.

Valid types: `feat` · `fix` · `docs` · `chore` · `ci` · `refactor` · `style` · `test` · `perf` · `revert` · `build`

---

## Branch Naming

Format: `<prefix>/<MAJOR.MINOR.PATCH>[/description]`

Approved prefixes: `dev/` · `rc/` · `version/` · `patch/` · `copilot/` · `dependabot/`

---

## Keeping Documentation Current

| Change type | Documentation to update |
|-------------|------------------------|
| New or renamed PHP class/method | PHPDoc block; `docs/api/` entry |
| New or changed manifest.xml | Update `updates.xml` version; bump README.md version |
| New release | Prepend `<update>` block to `updates.xml`; update CHANGELOG.md; bump README.md version |
| New or changed workflow | `docs/workflows/<workflow-name>.md` |
| Any modified file | Update the `VERSION` field in that file's `FILE INFORMATION` block |
| **Every PR** | **Bump the patch version** — increment `XX.YY.ZZ` in `README.md`; `sync-version-on-merge` propagates it |

---

## Key Constraints

- Never commit directly to `main` — all changes go via PR, squash-merged
- Never skip the FILE INFORMATION block on a new file
- Never add `defined('_JEXEC') or die;` to CLI scripts or model tests — only to web-accessible PHP files
- Never hardcode version numbers in body text — update `README.md` and let automation propagate
- Never use `github.token` or `secrets.GITHUB_TOKEN` in workflows — always use `secrets.GH_TOKEN`
- Never let `manifest.xml` version, `updates.xml` version, and `README.md` version go out of sync
