The netcode core of the 4-socket kit (Phase1_Combat_Gym_Build_Spec §1,§2,§5; review NP-1/ RS-1/DB-1/DB-3): - PlayerInput: +4 Socket0..3 InputEvents + Burst-safe GetSocket(i); legacy Fire kept vestigial. - PlayerInputGatherSystem: gather sockets from keyboard 1..4 (+gamepad RT/LB/RB); socket 0 also fires on the legacy primary (right-click / pad LT) as a bridge. - AbilityFireSystem: query dropped to 4 type args (PlayerInput/PlayerFacing/LocalTransform/ GhostOwner) + BufferLookup<AbilitySocket>/ComponentLookup<SocketCooldown>/BufferLookup< EffectiveSocketStats> (the 7-arg-cap fix); loops 4 sockets; per-socket cooldown + per-socket effective stats; Cone + Projectile dispatch per socket (predict-spawn Projectile-only). - ProjectileSpawnId.Pack: pure Burst-safe key owner14|socket2|fireCount12|fork4 so same-tick multi-socket projectiles never collide; AbilityFireSystem uses it. L1 clean; L2 494/494 (+5 ProjectileSpawnId tests: distinct-per-socket, fork, owner, bit-ranges, count-wrap). L3 two-player + rollback is the group-A gate (after step 2.5). Note: the client feel layer (muzzle/anim) still reads the legacy cooldown until step 2.5; sockets bake empty until content (step 4), so nothing fires in-game yet.
