Recovered/ holds the code linked only into the standalone exe (scripts/exe/build_exe.py), outside the Clank source dirs: - jsoncons/ and nProtect/ moved from scripts/exe/; GameGuard stand-in follows main's renamed entry points. - GPak/PakAuxiliary.cpp: Extract (virtualised in every build; 02-19 jumps out at 0x0065861E) rebuilt from the open GRF Editor decoder, after the visible 02-19 prologue; inline key and kRO keys 1-4. Apply traps (unreachable in 02-19). - GGHash/GGHash.cpp: CGGHash::Load/Check/VerifyHash trap (RagHash.dat check unreachable in 02-19). The whole client links: 984 units, 0 unresolved.
