Retail oracle: CPartArray::InitParts@0x00517F40, CGfxObj::Serialize@0x00534970 (physics_bsp
gated on serialized-flags bit-0), CPhysicsPart::find_obj_collisions@0x0050D8D0 (returns OK /
passable when physics_bsp==null). Render-mesh bounds never enter collision.
Changes:
- GameWindow.cs: delete the ~200-line VISUAL mesh-bounds collision block (the
isPhantomSetup / isPhantomGfxObj locals + the if-block computing worldMin/worldMax
AABB + the ShadowObjects.Register call that capped and registered the synthetic
cylinder). Also removes dead counter variables scHaveBounds/scRegistered/scNoBounds/
scTooThin; trims the ProbeBuildingEnabled summary line accordingly.
- PhysicsDataCache.cs: delete IsPhantomGfxObjSource (the predicate that only existed
to fence the mesh-AABB synthesis; the "phantom" concept is now the default — no DAT
shape means no registration, verbatim with retail).
- PhysicsDataCachePhantomSourceTests.cs: deleted (tested the removed method).
- ShadowShapeBuilderShapeSourceTests.cs: new guard test — a Setup with parts but
hasPhysicsBsp=false and no CylSpheres/Spheres yields an empty shape list, locking
the DAT-only rule in the builder.
- retail-divergence-register.md: AP-2 row deleted (divergence retired).
Objects with no DAT physics shape (no CylSpheres, no Spheres, no part with a
PhysicsBSP) now register no collision shape and are passable, verbatim with retail.
Objects with real DAT shapes (BSP parts, CylSpheres) are unaffected.
dotnet build green, 22/22 tests passing (ShadowShapeBuilderShapeSourceTests +
CellarUpTrajectoryReplay + CornerFlood + Issue147ArwicBuildings replay harnesses).
Visual gate pending: walk Holtburg + open world; objects that become passable must
match retail (DAT has no physics shape — trees with real CylSpheres still solid).
