libSceNpEntitlementAccess technical debt

sceNpEntitlementAccessGetAddcontEntitlementInfoIndividual, sceNpEntitlementAccessPollConsumableEntitlementInfo, sceNpEntitlementAccessRequestConsumableEntitlementInfo, sceNpEntitlementAccessRequestConsumeEntitlement (libSceNpEntitlementAccess) - their names and NIDs are in the PS5 3.20 export inventory, but no credible prototypes were found. They are declared without parameters solely to resolve known imports; this is not an ABI claim
sceNpEntitlementAccessGetEntitlementKey - the three-argument signature, 16-byte key and errors 0x817D0002/0x817D0007 follow KytyPS5; PPSA01521 passes a service label, entitlement label and output pointer. Only the no-key path is implemented: local entitlement labels carry no keys, and the output is untouched on failure. Console error precedence and key provisioning are unverified
Entitlement requests and polls: native argument lists are restored for single-item, list and consume operations, plus abort/delete. Request IDs are 64-bit, labels occupy 20 bytes and transaction IDs occupy 72 bytes. List options occupy 32 bytes and results have a 64-byte stride; their field semantics and three list-result scalars remain unresolved. The existing signed-out responses do not reproduce native initialization, validation or asynchronous request handling; abort/delete throw until request tracking is implemented.

sceNpEntitlementAccessGetGameTrialsFlag, sceNpEntitlementAccessGetPftFlag (libSceNpEntitlementAccess) - reports a full game, not a game trial or Play First Trial: writes 0 to the uint32_t output and returns 0, and a null pointer returns 0x817D0002. The single-pointer signature, the value, the one-word write and the error of sceNpEntitlementAccessGetGameTrialsFlag follow sharpemu, which has no sceNpEntitlementAccessGetPftFlag; those of sceNpEntitlementAccessGetPftFlag follow dlc_emu, which takes the same SceNpEntitlementAccessGameTrialsFlag* as the trials flag, writes the OFF value 0 and returns the parameter error for null; 0x817D0002 is the parameter error of KytyPS5, prosper and sceNpEntitlementAccessGetEntitlementKey, while sceNpEntitlementAccessGetSkuFlag here returns 0x80558003. None of this is a console measurement, and PRAGMATA (PPSA02530) shows four live registers at the call, so further arguments are not ruled out
