 | professions/trainers | every Engineering trainer group offers a visitor exactly the twelve TBC master-tier recipes its class can learn — and none of the others, so a broken class filter fails too. Eleven are class-restricted goggles: four classes cover all twelve across the eight groups, two characters per class cover the Horde/Alliance and Aldor/Scryer interaction splits, and the remaining five classes pin the armour-type sharing at Technician Mihila. Why a hidden recipe is hidden is pinned too: either the class cannot wear the goggle at all — the refusal read from SMSG_INVENTORY_CHANGE_FAILURE, which must be EQUIP_ERR_NO_REQUIRED_PROFICIENCY — or the goggle is another class's within the same armour type, which is why armour proficiency would be the wrong filter to gate on | P2 | covered (`TestAC_27146_*`) | #27146 |
 | world/dalaran | Dalaran's faction guards eject a hostile player from the Silver Enclave and Sunreaver's Sanctuary, and from nowhere else — public mailboxes, the street, the sewers and the neutral inn are left alone. Both directions are asserted: only checking public ground would pass a build where the guards never fire. One case parks a pet inside a quarter with its owner outside, since every other case is a lone player and would not notice the guard reading the owner's position instead of the trespasser's | P2 | covered (`TestAC_4467_*`) | #4467 |
