Full single-client capture replay (cl1 send=player seat, receive=opponent seat,
ts-ordered) ingests end-to-end: 33 frames, 0 rejects, 0 invariant violations at
turn boundaries (leader life/PP/board/hand).
Headless gaps filled per playbook (no Engine/ drift):
- IsRecovery=true after construction: the engine's own headless replay mode gates
the live view/UI layer off (BattleUIContainer, turn-control UI, VFX waits) while
keeping the live NetworkBattleReceiver (ND4) and authoritative state.
- Seed ToolboxGame.RealTimeNetworkAgent, BattleUIContainer, _backGround, and
per-player NullPlayerEmotion no-ops the receive/turn cycle dereferences.
- _IfaceImpl.g.cs (shim, not Engine/): BattleCardView.BattleCardIconAnimations
returns a lazy non-null no-op so the opponent card-reveal icon-init (deferred
VFX) doesn't NRE.
- HeadlessCardMaster.Load made cumulative: it replaced the global CardMaster each
call, so a Load(deck) evicted the oracle card set and broke tests run after.
Adds board-state accessors (LeaderLife/Pp/HandCount/BoardCount) and CaptureReplay
ts ordering.
