libSceDiscMap technical debt

Functional

• libSceDiscMap: loading disc bitmap metadata and resolving file byte ranges to bitmap blocks are not implemented. Both exports implement the confirmed no-bitmap path: return SCE_DISC_MAP_ERROR_NO_BITMAP_INFO before validating any argument and leave every output unchanged. The supplied module confirms signed 64-bit byte offset/size, a 32-bit IsRequestOnHDD result and three 64-bit outputs for ioKMruft1ek. The latter outputs describe the bitmap selector, first block and block count. Its exported source name remains unavailable.

Unknown function info

• sceDiscMapGetPackageSize (libSceDiscMap) - its name and NID are in the PS5 3.20 export inventory; the (int64_t, int*, int*) prototype follows shadPS4, is not measured on a console, and every call throws
