/** |

* MxChat Licence Check — asks mxchat.ai whether this site's domain is still |
| 4 |
* switched on for its licence key, and honours an explicit "off" from the |
| 5 |
* licence holder's My Account after a three-day grace period. |
| 6 |
* |
| 7 |
* Plan: plan-mxchat-20261007-c93ede (Support Ticket 467). An Agency licence |
| 8 |
* holder who resells to clients could see the domains activated on a key but |
| 9 |
* had no way to switch one off, and even a server-side unlink left the old |
| 10 |
* install running Pro: `mxchat_license_status` is a local option written at |
| 11 |
* activation and never re-checked. |
| 12 |
* |
| 13 |
* The rules, from Maxwell's approval note (they override the original spec): |
| 14 |
* |
| 15 |
* 1. Turning back on is immediate. A site that is off (or in its grace |
| 16 |
* period) re-checks when an admin opens any MxChat screen, at most once a |
| 17 |
* minute; on the "Check license now" button; and hourly in the background. |
| 18 |
* Activating from the site's own Activate button stays instant as before. |
| 19 |
* 2. A site that is on checks once a day, at a random time per site. |
| 20 |
* 3. ONLY AN EXPLICIT "OFF" COUNTS. A timeout, a 5xx, a non-JSON body, a DNS |
| 21 |
* failure or an mxchat.ai outage never switches a site off. Today's |
| 22 |
* production endpoint does not know this route yet and answers |
| 23 |
* {"success":false,"data":"Invalid action"} — that is an error here too, |
| 24 |
* so a core shipped ahead of the website change keeps every site on. |
| 25 |
* 4. A site move is not "off". A valid key on a domain mxchat.ai does not |
| 26 |
* recognise ("unknown") stays on. |
| 27 |
* 5. Grace period: after the first explicit off the admin sees a notice and |
| 28 |
* Pro is switched off only when an off answer arrives three days after the |
| 29 |
* first one with no on/unknown in between. Nothing else is touched: |
| 30 |
* settings, knowledge, the saved key and email, and the free features all |
| 31 |
* stay exactly as they are, so switching back on restores Pro in place. |
| 32 |
* |
| 33 |
* What is sent to mxchat.ai: the licence key, the account email, the site's |
| 34 |
* host name and the plugin version (the same three identifiers the existing |
| 35 |
* activate / deactivate / check-domain calls already send, plus the version). |
| 36 |
* The readme's "External services" section documents all four calls. |
