// 
// Whitelist of AgentConfig templates whose client-side enemy HUD actually binds.
// Why this exists: the enemy HP bar is not created by anything the server pushes. From
// EnemyHUDCtrl.lua the HUD binds only when AgentConfig[agentId].ShowHPBar is
// true, and RefreshHpVisible additionally needs no hide / near-death state. Pushing
// SyncUnitAttrs (attr 1) + SyncUnitHp + SyncUnitAttacked is enough to render and flash a bar
// on a template that has one, and is not enough to conjure one on a template that does not.
// The general summon catalog (AgentSummonCatalog.json, 9015 rows) is the unfiltered
// AgentConfig projection: 7051 of its rows carry InitWeaponId = 0. Those templates have
// no HP bar, so an enemy spawned from them fights, takes damage and dies with no visible bar —
// which reads as "I cannot kill it". This file is the filtered set (ShowHPBar && InitWeaponId >
// 0): every id here is guaranteed to bind a bar.
