-# Repository Guidelines
-
-## Project Structure & Module Organization
-adsPRO is a custom PHP MVC app. Keep business logic in:
-- `autoload/controls/` (`class.*.php`): request handling (`\controls\*`)
-- `autoload/factory/` (`class.*.php`): DB access via Medoo (`\factory\*`)
-- `autoload/view/` (`class.*.php`): view composition (`\view\*`)
-- `autoload/services/`: external integrations (Google Ads, OpenAI, Claude)
-- `templates/`: PHP templates rendered with `\Tpl::view()`
-- `migrations/`: SQL migrations (`NNN_description.sql` + optional `demo_data.sql`)
-- `layout/`: SCSS/CSS assets (`style.scss` -> `style.css`)
-
-Main entry points are `index.php`, `ajax.php`, `api.php`, `cron.php`, and `install.php`.
-
-## Build, Test, and Development Commands
-- `php -S 127.0.0.1:8000` - run a local PHP server from repo root.
-- `php install.php` - apply pending DB migrations.
-- `php install.php --with_demo` - apply migrations and demo data.
-- `php install.php --force` - re-apply tracked migrations.
-- `php -l autoload/controls/class.Campaigns.php` - lint a changed PHP file.
-
-There is no dedicated build pipeline; frontend dependencies are committed in `libraries/`. SCSS is typically compiled via VS Code Live Sass Compiler.
-
-## Coding Style & Naming Conventions
-- Follow existing PHP style: spaces inside parentheses (`if ( $x )`), braces on new lines.
-- Use `PascalCase` class names, lowercase namespaces (`\controls`, `\factory`), and `snake_case` for methods/variables/DB columns.
-- Controllers/factories are conventionally `static public function ...`.
-- Keep route/module naming aligned with URL pattern `/module/action/...`.
-
-## Testing Guidelines
-No first-party automated test suite is maintained in this repo. Validate changes with:
-- PHP lint on edited files.
-- Manual UI checks for affected `templates/` views.
-- Endpoint checks for `ajax.php`, `api.php`, or `cron.php` paths you touched.
-- Migration dry run on a non-production database when schema is changed.
-
-Document manual test steps and outcomes in each PR.
-
-## Commit & Pull Request Guidelines
-- Use concise Polish commit messages with prefixes seen in history: `feat:`, `fix:`, `update:`.
-- Keep commits focused (feature, refactor, migration, UI tweak).
-- PRs should include: scope summary, linked issue/task, migration notes, manual test checklist, and screenshots for UI changes.
-
-## Security & Configuration Tips
-`config.php` contains environment credentials. Do not introduce new secrets in commits or PR discussions, and treat any credential change as a coordinated ops task.
