libSceGameUpdate technical debt

Silent stubs

• sceGameUpdateCreateRequest, sceGameUpdateCheck, sceGameUpdateGetAddcontLatestVersion (libSceGameUpdate) - no patch service is asked. Check answers no update (found and the byte after it cleared, the rest untouched, return 0), what the module returns when its service reports 0x80412883. sceGameUpdateGetAddcontLatestVersion clears found and returns 0 after its argument and initialization checks; its service path in the module is not read. Requests use the module's 8 slots with ids from 0x20000000 (a ninth returns 0x80412806, an aborted request's Check 0x80412807), as prosper reads the PS5 3.20 libSceGameUpdate.sprx. Offline console answers are not measured. PPSA22408 aborted on the throw in sceGameUpdateCreateRequest, PPSA24263 on the one in sceGameUpdateGetAddcontLatestVersion. Closes when: measured on a PS5

Unknown function info

• sceGameUpdateCheckTitle has an unknown signature and behaviour. The parameterless int declaration is an import-resolution placeholder, not a confirmed ABI signature, and every call throws through NotImplemented_nid_no_patch. Only its name and NID sGNKn-jXzHQ are established by the 13.60 export inventory; not measured on a console.

Functional

• libSceGameUpdate: initialization tracks host state but does not connect the patch service.
• sceGameUpdateCheck: option zero is supported for argument validation. The original additionally permits option one when a kernel platform predicate succeeds; that platform mode is not modeled. Three titles disassembled for this entry (PPSA01494 01.100.002 at 0x63f1982, PPSA30839 01.003.000 at 0x6bf0c92, PPSA31162 02.000.001 at 0x6a204e1) pass option zero: right after sceGameUpdateCreateRequest they fill both the parameter and the result with a 64-bit size of 0x30 and zeros after it. On a non-negative return they read only found (PPSA01494 tests it for nonzero, the other two for 1), never addcont_found or content_version; PPSA01494 and PPSA30839 then call sceGameUpdateDeleteRequest whatever the result.
• sceGameUpdateGetAddcontLatestVersion: the supplied module confirms a 20-byte entitlement-label input and a 48-byte service output. Null pointers are rejected before initialization is checked. There is no local output-size validation or blanket clearing of the output; answers found = false and returns 0 without contacting the patch service, matching sceGameUpdateCheck.
