The DAT file reader had several bugs inherited from the old C++ reference code, which targeted an older format version. Verified and fixed against real client_portal.dat and client_cell_1.dat files: - Fix header offset: BTree root is at 0x160, not 0x148 (file size field) - Fix BTree entry size: 24 bytes (flags+id+offset+size+timestamp), not 12 - Fix sector-chain node reading: BTree nodes span multiple sectors via linked-list headers; must assemble node data across sector boundaries - Fix DatStreamImpl.Read() BSTR handling: use Buffer.BlockCopy to match C++ SysAllocStringByteLen instead of Marshal.PtrToStringAnsi - Fix DatStreamImpl.ReadBinary() pointer lifetime: inline fixed block to keep destination buffer pinned during Marshal.Copy - Document LoadFilters() dependency on parameterized COM properties in IDecalCore.Configuration that need IDispatch to call correctly Add smoke test project (13/13 tests pass against real DAT files).
