ServerClientChannel struct
#include <Runtime/Net/Public/ServerClientChannel.h>

Authority-side state for one connected Owner. The unit of per-client replication.

Owns the inbound PlayerInputLog, per-entity Replicated[] bitvector, NetChannel typed send wrapper, and outbound PendingPacketQueue. Lives inside the World's ReplicationSystem — PIE worlds are isolated naturally.

Public functions

void Open(uint8_t ownerID, uint32_t logDepth, ConnectionInfo* ci, NetConnectionManager* mgr, uint32_t entityCapacity = 0): Open the channel — allocates the input log and sets OwnerID.
void Close(): Close the channel and release all resources.
auto IsReplicated(uint32_t index) const -> bool
void MarkReplicated(uint32_t index): Mark slab index index as replicated (EntitySpawn sent).
void ClearReplicated(uint32_t index): Clear the replicated flag for index (entity destroyed).
void EnsureCapacity(uint32_t count): Grow the Replicated vector to cover at least count slots.

PlayerInputLog InputLog: Inbound input frames from this Owner.
std::vector<bool> Replicated: Per-slab-index spawn tracking; true = EntitySpawn sent.
std::vector<uint32_t> PendingActivations: Net handle values queued for EntityActivate; drained once Playing.
NetChannel Channel: Typed per-connection send wrapper.
PendingPacketQueue SendQueue: Worker-push / Sentinel-drain MPSC queue.
std::optional<PendingPacket> PendingPlayerConfirm: Held until spawns are in SendQueue; pushed in Flush().
uint32_t PendingPlayerConfirmSpawnFrame: Minimum LastDispatchedFrame before confirm may be pushed.
ConnectionInfo* CI: GNS connection state (non-owning).
uint8_t OwnerID: Stable session identity (1–255; 0 = server).
uint32_t LastAckedSimFrame: Last simulation frame this client confirmed receiving.

Returns	`true` if a `EntitySpawn` has been sent for `index`.
