libSceGameUpdate technical debt

Silent stubs

• sceGameUpdateCreateRequest, sceGameUpdateCheck (libSceGameUpdate) - requests are kept in 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. Check never asks a patch service: it always answers no update (found and the byte after it cleared, the rest of the result untouched, return 0), which is what the module returns when its service reports 0x80412883; KytyPS5 also answers no update. What the service returns on an offline console is not measured. The answer only decides whether a title offers a patch. PPSA22408 aborted on the throw in sceGameUpdateCreateRequest at its title screen. Closes when: measured on a PS5

Functional

• libSceGameUpdate: initialization tracks host state but does not connect the patch service. Entitlement version lookup throws.
• 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; the host leaves it untouched when the missing service causes an exception.
