First proof that follower DEATH / board-removal commits in the authoritative part of PlayCard headless (not the cosmetic post-Process tail). Card 800144120 (cost-0 when_play destroy of a select_count=1 enemy follower) resolves via the M6 selectedCards path: selected enemy follower removed (board -1 + cemetery +1), un-selected untouched (routing confirmed load-bearing by swapping the selection). Shim gap fixed (the predicted M7 cost): SkillProcessor.SelectCardToHaveDestroyVoicePlay's cosmetic death-voice tail NRE'd on three M1 default!/Null* shadows (IBattleCardView.VoiceInfo, CardVoiceInfoCache.GetCardVoiceInfoForBattle, ReadOnlyVoiceInfo.GetDestroyVoice — the last unusable as the interface since m1_stub_gen dropped its : IReadOnlyVoiceInfo base). Fix = one hand shim HeadlessVoiceInfo : IReadOnlyVoiceInfo returning the engine's own VoiceAndWaitTime._nullVoice sentinel, wired into the two generated seams with // HEADLESS-FIX markers. No Engine/ edit (drift clean). dotnet test SVSim.BattleEngine.Tests -> 7/7 green; check_drift.py clean; engine 0 Error(s). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
