The player's Attack (the Attack Target key, `AttackTarget()` and the Attack action button) now picks its target as 1.12.1's validator `0x612df0` does, where before it swung at whatever was selected, a friendly unit or a corpse included.
- With nothing selected, or a unit the player is friendly toward (reaction ≥ 4, `0x6130a3`), it runs the Tab cycler for the nearest enemy (`0x6130b5` → `0x493f60`), which commits the new selection at once, so `AttackTarget()` then `/cast` in one script casts at the new target.
- It then reads the selection again (`0x6130c1`): none raises "There is nothing to attack." (`0x6130d9`); a unit neither alive nor feigning, or one `CanAttack` (`0x606980`) rejects, raises "You cannot attack that target." (`0x613171`). A friendly unit with no enemy near stays selected and meets that second gate.
- The swing toggle runs only once a target is accepted (`0x6131a0`), so Attack at a corpse mid-swing gives the error and keeps the swing.
- The pet's attack order shares the same pick. vmangos stops a swing at a friendly or dead target server-side (`CombatHandler.cpp:46-59`), which the client no longer sends.
