Replaces partial EffectMgr.EffectType with all 226 decomp values; copies the IsNotNullOrEmpty/EquelsID/FindFromCardId/GetAllFuncVfxResults extension files + UI extensions; adds Renderer/MeshFilter shared-material/mesh/sortingOrder. Compile loop then closed the revealed deps (3242 files). 9.1k -> 18 errors.
Copied the 89 uncopied AI*SimulationUtility/extension files defining the AIVirtualCard/AIVirtualField extension methods; the compile loop then auto-closed the revealed type deps (~3049 files total, drift-clean). 10.0k -> 62 errors.
Authored Unity primitive/object-model shim, VFX layer (control-flow-preserving, InstantVfx never invokes its action -- headless suppression), god-object stubs (GameMgr/EffectMgr/UIManager with faithfully-extracted nested enums), View/UI/Touch tree, LitJson+BetterList+Tuple copied, third-party stubs. Discovered Roslyn header-error masking: fixing class-header type errors unmasks body references, so the true copy closure is ~2570 files (was 782 under masking). Errors: masked-25720 -> 268; our shim files compile clean. Remaining: ~50 residual shim/external types, 24 NGUI UI-base overrides, static-type fixes, plus likely 1-2 more unmask waves.
Compile-driven bulk-copy loop (tools/engine-port/m1_copy_loop.py) pulled the precise reference closure of the battle-core roots, stopping at the classify god-object/View-VFX-UI boundary. 782 files; no re-explosion (M0 had estimated ~order 1000). Residual frontier = 52 shim-classified + 80 external (Unity/BCL) types to author next.
