Editor-only class swap via the existing scalar dev-RPC family (new DebugOp.SetClass): F1/F2 keybind (ClassSwitchHotkeySystem), DebugOverlay '- Class -' buttons, and DebugCommandSendSystem.SetWarrior/SetRanger/SetClass statics. Server (DebugCommandReceiveSystem) swaps class in place on the spawned player: strips+re-seeds the ClassTraits StatModifier seeds, swaps the AbilityRef Fire slot, resets the ability cooldown, and heals a LIVING player to the new max (dead players skip the heal so respawn isn't raced). Server-authoritative + prediction-correct (same buffer-mutation path as GrantUpgrade); wire type unchanged so the RpcCollection hash is unaffected.
ClassTraits gains a shared Seeds core (spawn + swap can't drift), ClassSeedCount, IsClassSeed, a DynamicBuffer AppendSeeds overload, and Reapply. +3 EditMode tests (exact-count round-trip, value-equality fold, boundary/foreign-mod preservation); 351/351 green; Warrior<->Ranger round-trip Play-validated (server+client agree).

The per-player class travels on GoInGameRequest.ClassId (client reads a ClassSelection
singleton); GoInGameServerSystem seeds the class at spawn via ClassTraits (AbilityRef +
permanent trait StatModifiers on a reserved ClassSourceId; CharacterStatsRef stays Default
so the DRG-asymmetry deltas ride the replicated OwnerSendType.All buffer). AbilityFireSystem
gains the aim-directed Cone archetype: cooldown predicted both worlds, server-only cone
damage to living enemies (same-tick, SourceTick-stamped, like the melee cleave). 345/345.
