## Architecture

- **Single meta box** (`review_metabox`) covers all schema types — field visibility toggled by `js/toggle.js`
- **Post meta key prefix:** `_bsf_` (leading underscore hides from WP Custom Fields panel)
- **Type selector:** `_bsf_post_type` — integer 0/1/2/5/6/7/8/9/10/11
- **Options prefix:** `bsf_*` (e.g. `bsf_review`, `bsf_product`, `bsf_custom`)
- **Front-end output:** `display_rich_snippet()` on `the_content` filter — outputs Microdata HTML
- **AJAX handlers:** `bsf_submit_rating`, `bsf_update_rating` (public), `bsf_submit_color`, `bsf_submit_request` (admin)
- **Third-party libs:** BSF Analytics (`admin/bsf-analytics/`), NPS Survey (`lib/nps-survey/`), Astra Notices (`lib/notices/`)

## Schema Types

| Value | Type | Option Key |
|---|---|---|
| 1 | Item Review | `bsf_review` |
| 2 | Event | `bsf_event` |
| 5 | Person | `bsf_person` |
| 6 | Product | `bsf_product` |
| 7 | Recipe | `bsf_recipe` |
| 8 | Software Application | `bsf_software` |
| 9 | Video | `bsf_video` |
| 10 | Article | `bsf_article` |
| 11 | Service | `bsf_service` |

## Gotchas

- **WooCommerce exclusion:** By default, `product` post types are excluded from the meta box. Toggle in admin Tab 5 or use `bsf_exclude_custom_post_type` filter.
- **`BSF_META_BOX_URL` constant:** Defined in `init.php` with Windows path handling — don't redefine it.
- **Pre-commit hook blocks literal conflict markers** (7x `<`, 7x `=`, 7x `>`) in any committed file — including docs. Use alternative notation in documentation.
- **PHPCS excludes:** `lib/`, `vendor/`, `admin/bsf-analytics/`, `node_modules/`, `stubs/` — don't add production code there expecting it to be linted.
- **PHPStan baseline:** `phpstan-baseline.neon` suppresses known false positives — add new intentional patterns here rather than inline ignores.
- **Text domain is `rich-snippets`** (not the plugin slug `all-in-one-schemaorg-rich-snippets`).
- **`register_activation_hook`** is called in `index.php` and seeds options via `settings.php` — re-running `add_option()` is safe (won't overwrite existing values).
- **Schema Pro detection:** `is_schema_pro_installed()` checks for `wp-schema-pro/wp-schema-pro.php` file existence to conditionally show the "Get Schema Pro" upsell.

## Development Notes

- Run `composer format` before every commit to avoid PHPCS failures
- PHPStan must pass with no new errors — add to baseline if suppression is intentional
- All user input must be sanitized; all output must be escaped (see WPCS rules)
- Nonce verification required on all AJAX handlers before processing
- `manage_options` capability check required for admin-only AJAX actions
