/** |

* Fired when the plugin is uninstalled (deleted via the WordPress admin). |
| 4 |
* |
| 5 |
* WCPOS distinguishes three kinds of data: |
| 6 |
* |
| 7 |
* - Derived/operational state — sync tables (rebuildable from WooCommerce |
| 8 |
* data on reinstall), cron events, transients, the print-job queue, JWT |
| 9 |
* secrets/tokens, sync watermarks and version latches, plugin-owned upload |
| 10 |
* directories and log files. Always removed. |
| 11 |
* |
| 12 |
* - User-authored configuration — POS settings, receipt templates (and their |
| 13 |
* revisions, taxonomies, and options), the receipt sequence counter, the |
| 14 |
* cashier role. Preserved by default (a delete/reinstall cycle must not |
| 15 |
* destroy a merchant's receipt designs or numbering continuity). Removed |
| 16 |
* only when a full wipe is requested via the WCPOS_REMOVE_ALL_DATA |
| 17 |
* constant (wp-config.php) or the wcpos_remove_all_data option. |
| 18 |
* |
| 19 |
* - Data owned by others — WCPOS Pro's options (woocommerce_pos_pro_*, |
| 20 |
* wcpos_stores_migrated) are NEVER touched, even on a full wipe: they |
| 21 |
* belong to a different plugin. POS metadata on orders/products |
| 22 |
* (_woocommerce_pos_* post/order meta) is part of WooCommerce's order |
| 23 |
* history and is also never touched. |
| 24 |
* |
| 25 |
* This file runs standalone — the plugin is NOT loaded — so table, option, |
| 26 |
* hook, and post-type names are hardcoded. Test_Uninstall guards them |
| 27 |
* against drift from the class constants. |
| 28 |
* |
| 29 |
* There is deliberately no is-this-really-an-uninstall guard at the top: |
| 30 |
* the file only defines functions, and the sweep at the bottom is gated on |
| 31 |
* WP_UNINSTALL_PLUGIN. Loading the definitions (tests, direct access) has |
| 32 |
* no side effects. |
