Source the played card's opponent-facing knownList[].cardId off the shadow engine (SessionBattleEngine.PlayedCardId -> BattleCardBase.CardId), engine-first with the wire-mined idx->cardId map as the fallback. PROVEN engine-resolved (each backed by a HeadlessConductorTests PlayedCardId_* test): deck cards and receive-path substituted/ revealed tokens (engine seats the wire id at the wire idx). PARTIAL retirement: the wire-mining bookkeeping (MineAddOps/MineChoicePicks/MineCopyTokens + Record*From) is KEPT as the load-bearing fallback. The choice/Discover, copy/clone and cross-side (isSelf:0) token cases are NOT proven to resolve at a wire idx headless — the autonomous token_draw path seats a chosen token at engine Index 0 (would collide with the leader), and copy/cross-side aren't cheaply fixturable. Deleting their mining on faith would silently corrupt opponent reveals, so it stays behind a TODO(M-HC-4f) gate. - SessionBattleEngine.PlayedCardId: new accessor mirroring PlayedCardClan/Tribe. - BuildPlayedCard: signature deckMap->explicit cardId; null on cardId==0 (no engine id AND no mined/deck-map fallback). - PlayActionsHandler: cardId = engine.PlayedCardId(seat, idx, fallback: mapped) ; mining retained. - Tests: PlayedCardId_* (deck/substituted/degrade pass; choice-gap [Explicit] documents the Index-0 finding). KnownListBuilder + CaptureConformance call-sites updated to new signature. Full BattleNode suite 263/263 green; HeadlessConductorTests 27/27; drift clean; no Engine edits.
