Its virtual slot `+316` and its exclusive key count at `+320`: the first dword of an entry is a stored-record pointer and its byte at `+4` selects a 212-byte profile bank. A key outside that count, or an entry pointer below `0x1000`, fails the lookup. + +The static constructor now identifies this object as the embedded `CLandscape` +subobject whose vtable is `Terrain.dll` RVA `0x643D0`. It installs that vtable +at parent offset `+316`, allocates the entry table at parent `+632` (subobject +`+316`) as `0x1f40` bytes / 1,000 eight-byte entries, and initializes its count +to zero. The profile-bank region starts at subobject `+332`: every one of the +100 banks has a 116-byte header followed by a 96-byte initialized stream, hence +the recovered 212-byte stride. The byte selected from each table entry is +therefore a bank index into a constructor-owned, fixed 100-bank region. This +proves the cache's allocation layout; it does **not** yet identify the code that +populates individual entry records from map resources. + On success the method returns the shared result view at cache offset `+24`, not the stored-record pointer and not a WEAR row.
