Six distinct fixes accumulated over live-test iterations against four bids
(654473755566, 806245601092, 283192092460, 131549100204, 799755786270) — together
they take the shadow engine from "throws on the first non-mulligan play" to
"survives a full PvP battle, only weird-edge-case Unity touches still left to whack".
1. Engine StableRandom seed aligned with clients' Matched.seed
(BattleSession.EnsureEngineSetup, NodeNativeBattleHarness.Create). Clients seed
_stableRandom with BattleSeeds.Stable(masterSeed) (the value the node ships in
Matched.seed); we were passing the RAW masterSeed to engine.Setup, so every
StableRandom call diverged from call #1 onward — every turn-1+ draw picked a
different deck position than the clients. Verified Stable(1184631275)=1543475792
matches the wire on bid 654473755566.
2. SeedDeck advances cardTotalNum to deck.Count+1 + pins BattleStartDeckCardList.
Mirrors SBattleLoad.InitPlayer's tail (SBattleLoad.cs:1292). Without it,
skill-generated tokens auto-assigned Index 0,1,... and COLLIDED with deck-loaded
indices 1..40 — silent until something addressed the deck card with the
colliding Index (Hoverboarder at deck idx 1 + a token at engine Index 1 made
GetBattleCardIdx's SingleOrDefault throw on bid 806245601092).
3. BattleCardView.GameObject lazily non-null in the shim (ViewUiTouchStubs.cs).
The IsRecovery card-create delegate (NetworkBattleManagerBase.cs:379) passes
null cardGameObject; Skill_metamorphose.cs:147 in the in-play branch then NRE'd
on `metamorphosedCard.BattleCardView.GameObject.transform.rotation = identity`,
a purely cosmetic touch with no game-state implication. Bid 283192092460:
Petrification on a board follower.
4. TranslateChoiceKeyAction unwraps wrapped selectCard on shadow ingest
(SessionBattleEngine.cs, sibling to TranslateTargetOwners). Live sender-send
wires Choice plays as selectCard:{cardId:[...], open:0}; engine's
ConvertToListInt does `value as List<object>` — a Dict casts to null and
foreach NREs. The receiver's swallow-all catch (NetworkBattleReceiver.cs:1255)
logs to Debug.LogError + LocalLog — both shimmed/no-op'd headlessly — and
returns false, but Receive calls ReceivedMessage with checkBreakData:false so
the false isn't propagated. The play continues with choiceIdList=[], the chosen
branch never resolves, the played card stays in hand; a later targeted play
(A's bounce on B's "board" idx 20) then can't find the target → NRE on null in
ActionProcessor.PlayCard:407. Bid 131549100204: B's Resonance + A's bounce.
Opponent-relay path is unaffected — node strips selectCard from broadcasts.
5. HeadlessHandViewStub overrides HandUnfocus/HandFocus/FocusRearrangeHandHand
to return NullVfx. CreateHandControl returns null in headless; the base
methods unconditionally deref `_handControl.SetHandState(...)`. A follower
with a when_spell_play Heal trigger fired on its leader for amount 0 — even
a 0-heal drives ApplyHealing → CreatePullHandInVfx → HandUnfocus → NRE.
Bid 799755786270: two consecutive spell plays both crashed this stack.
Added InternalsVisibleTo("SVSim.BattleEngine.Tests") so the shim-level
regression tests can pin the no-op contracts directly.
Plus the previous-session fixes carried in this same uncommitted state
(see docs/superpowers/plans/2026-06-07-shadow-engine-desync-handoff.md):
- doesPlayerGoFirst:true + mgr.IsFirst:true (turn-1 draw count correct
per seat)
- RecoveryOperationCollection.PlayHandCardOperation routes all type:30
through PlaySkillSelectHandCardOperation (skips the two-phase user-select
guard that aborts targeted spells in recovery)
- ShadowFeed + ToRawBody: server-generated typed bodies (DealBody, etc.)
converted to RawBody before engine.Receive (`env.Body as RawBody`
returned null for typed bodies)
- Ready idxChangeSeed seeds A's XorShift via the receiver; B's seed is
injected via SeedOppoIdxChange (BattleSeeds.IdxChange + viewerId)
- ReadySpin defaulted to 0 (was 243) — non-zero double-cranks the shadow
which ingests BOTH sides' Ready frames on one stream
Test counts: SVSim.UnitTests 1054/1054, SVSim.BattleEngine.Tests 34/34.
Open: known-residual Unity touches are individual whack-a-mole now (per-card
skill edge cases), not the structural divergences fixed here.

Drive ATTACK frames through the headless receive conductor and assert on engine
board state (node-native harness). Two cases: follower -> enemy leader (leader
life drops by atk, attacker spent) and a lethal follower-vs-follower trade (both
removed). ATTACK opcode confirmed = 10 (NetworkBattleDefine.PlayActionType).
Headless view-untangle (no Engine logic edits; drift clean):
- IBattlePlayerView.AttackSelectControl -> non-null HeadlessAttackSelectControl
(no-op RegisterAttackPair/ResetCardAfterAttack); IsCardTranslatable left to base.
- IBattleCardView.CardInfo -> backing card via BuildInfo (so IsCardTranslatable
reads authentic IsClass); class/null view ctors now chain : base(buildInfo).
- IBattleCardView._inPlayFrameEffect -> non-null no-op control.
- Seed Certification.viewer_id headless so the IsRecovery target parse
(vid != UserViewerID) does not throw inside SavedataManager and silently drop
the parsed targetList.

- VFX: SequentialVfxPlayer.GetAllVfxAsList, ParallelVfxPlayer.GetVfxList,
VfxMgr.CheckAndAddEffectVfxList; point our own ShowBattleUIImmediatelyVfx stub at
NullVfx.GetInstance() (it called a non-existent NullVfx.Create).
- Static factories: SkillTargetSelectTouchProcessor.Create (10-arg),
DialogReportToManagement.Create(long).
- Re-add StartSkillSelectVfx.OnStart event (m1_stub_gen drops `event` decls — the
recurring session-6 gap; generator event-capture fix still pending).
- Stop the BattleCardView/GameObjMgr ctor cascade: parameterless ctors on the no-op
BattleCardView and GameObjMgr hand shims so non-chaining subclass/field stubs satisfy
their implicit base() call.
- Copy Cute/ListExtensions.cs (FisherYatesShuffle extension) verbatim into Engine.

- Add the (JsonData) ctor to the LoginBonus data hand stubs (Continuous/Normal/
Special/FreeCardPackBox) and StoryRecoveryData (LitJson.JsonData is copied).
- Full-surface the two nested View types that only the parent's empty stub covered:
BattleCardView.BuildInfo (14-arg ctor) and DestroyVfx.FileNamePair (ctors +
ObjectFileName/SeFileName); add BattleCardView(BuildInfo) to the hand shim.
- Regenerate Field/Spell/UnitBattleCardView: stale stubs whose ctors had dropped the
decomp `: base(buildInfo)` chain, exposed (CS7036) once BattleCardView lost its
implicit default ctor.

Generate the Main-namespace versions of the four colliding SelectionProcessing
dialog classes (ChapterCharaDecider/DownloadInfoGetter/DeckSelectionDialogDisplay/
DeckSelectionConfirmDialogDisplay) via the new --ns path — AreaSelectUI uses the
Main module and constructs them into an IProcessing[]. baseclauses binds each to
Main.ProcessingBase; iface_reattach (regenerated full) attaches Main.IProcessing.
Also fill IReplayRecordManager with its 3 real members (SetupRecording/
SetupBattleInfoFilter/SetupOperateMgrEvents); both implementors already had them.

- VfxWith<T> ctor params were swapped ((T,VfxBase) vs decomp (VfxBase,T)) -> ~38
CS1503 across SkillCollectionBase/BattleCardBase skill-processing (ProcessInfo
<-> VfxBase). These are on the resolution path. Fixed to match decomp.
- UnityEngine primitives: implicit Vector3/Vector2<->Vector4 + Color->Color32
conversions; Transform.Translate/Rotate(Vector3,Space) overloads (iTween).
- ITouchProcessor was dropped from touch-processor stubs by base-clause recovery;
re-attach via Shim/View/TouchProcessorIfaces.cs (interface-only for generated
full-surface stubs, interface+no-op members for the empty hand stubs).

Make the minimal hand shims partial + generate full member surface for the manager/
task/controller god-objects (LoadingViewManager/DeckUpdateTask/MyPageTask/ReplayController/
PlayerControllerForWatching/WatchDataHandler/EvolutionTouchProcessor/StoryChapterSelection
Utility/NonDialogPopup). NonDialogPopup given MonoBehaviour base + hand Close() removed
(superseded by full surface). LoadTask dup deleted (already copied verbatim). RoomMatch
watch/replay closure types stubbed. Copied 8 more closure files.
CS0246-in-generated-signature masking note: 4 such errors were hiding ~1582 — generated
CS0246 masks as hard as header CS0246; the real frontier is 1586 (CS7036 base-ctor +
member-level), 0 structural.

Stub-generate BattleLogManager(45)/BattleLogItem(17)/InPlayCardFrameEffectControl(4)
member surfaces from decomp signatures; declare BattleLogWindow+nested enum; make
BattleLogItem a MonoBehaviour so inherited gameObject/transform resolve.

Resolves the 268-error header frontier: settings Item base, ErrorDialog.Data,
RoomConnectController nested types, Unity asset/light/collider types, CriWare/
CodeStage/Spine SDK surface, and copies INetworkLogger + SingletonMonoBehaviour
verbatim. Per F3 this unmasks the type bodies (~26.5k member-level errors now
visible) -- the real M1 bulk, attacked in following waves.
