Replace the AP-79 P4 TargetTracker poll adapter with the ported retail
TargetManager voyeur subscription system, wired per entity. Behaviorally a
faithful no-op refactor for the common cases (server-directed creature chase
+ auto-walk-to-object), now driven by the retail mechanism instead of the
GameWindow poll.
New: EntityPhysicsHost (App) — the per-entity IPhysicsObjHost (retail
CPhysicsObj stand-in), owning a TargetManager. Delegate-injected accessors so
it stays free of GameWindow internals (code-structure rule #1).
Wiring (GameWindow):
- _physicsHosts registry (guid → host) = retail CObjectMaint::GetObjectA,
backing the voyeur round-trip's cross-entity delivery.
- ResolvePhysicsHost lazily creates a minimal position-only host for ANY known
entity — retail lets every CPhysicsObj host a target_manager, so a STATIC
object (chest/corpse) still answers add_voyeur; without this, auto-walk to a
never-animated object would arm the moveto but never receive the immediate
target snapshot and never start.
- MoveToManager set_target/clear_target/quantum seams repointed at the host's
TargetManager (remote + player).
- HandleTargetting ticked unconditionally per entity BEFORE UseTime (retail
UpdateObjectInternal order): per-remote loop for remotes, pre-Update block for
the player. The player's tick is load-bearing for creature-chase — the player
as a watched target pushes its position to the chasing NPCs' HandleUpdateTarget
each frame, ahead of their UseTime.
- Despawn (RemoveLiveEntityByServerGuid): NotifyVoyeurOfEvent(ExitWorld) to the
entity's watchers before pruning the host — the only cleanup for a watcher
whose target already sent an Ok (past Undefined, the 10s staleness never fires).
Deleted: RemoteMotion.TrackedTarget* fields + _playerMoveToTarget* GameWindow
fields + the two manual poll blocks. AP-79 register row retired same commit
(AP section 73→72).
Delivery is now synchronous-on-set_target (retail: set_target is last in
MoveToObject, so the immediate snapshot lands with all moveto state in place)
vs AP-79's next-frame poll — more faithful. Full suite 4006 green.
