Subject: [PATCH] Validator: discard promotional/training ads (workshops,
 courses)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Medical-flavored ads like «کارگاه بوتاکس و فیلر… ویژه پزشکان ۱۰٪» passed the
medical gate and got misclassified as a پزشک عمومی shift with a bogus 10%
share. Now: if a course/event/product marker is present and there's no
staffing intent (hiring/shift/availability), the item is auto-discarded.
