What

Adds sceNpEntitlementAccessGetEntitlementKey (NID 5LiMEPuW0DQ) to libSceNpEntitlementAccess. It is the only import of God of War Sons of Sparta (PPSA28997) that no AnyPS5 library exports: Unity's Media/Plugins/PSN.prx imports it, so the relinked title stops at load with unresolved ELF import 5LiMEPuW0DQ from libSceNpEntitlementAccess.prx.

Signature, from the call site in PSN.prx (0x4400): int sceNpEntitlementAccessGetEntitlementKey(SceNpServiceLabel, const SceNpUnifiedEntitlementLabel*, SceNpEntitlementAccessEntitlementKey*). The caller copies the label into a 17-byte buffer, zeroes a 16-byte key and treats a negative result as failure. The name was matched by hashing it to the NID.

Behaviour:

• null label or key: SCE_NP_ENTITLEMENT_ACCESS_ERROR_PARAMETER;
• a label not listed in the entitlements file (anyps5-entitlements.ini / ANYPS5_ENTITLEMENTS): SCE_NP_ENTITLEMENT_ACCESS_ERROR_NOT_FOUND, the answer sceNpEntitlementAccessGetAddcontEntitlementInfo gives for the same label. The console's error for an unowned label is unverified and recorded in TechnicalDebt;
• a listed label throws NotImplemented, as AnyPS5 has no key for an add-on.

NpEntitlementAccessEntitlementKey (16 bytes) is added to SceTypes.hpp. The library gets its own CMakeLists.txt (same shape as libSceGameUpdate) so the test can link libc and catch the throw.

Tested

Windows 11 Pro 26200, WinLibs GCC 15.2.0, Release.

• New test guest_np_entitlement_access: null arguments, an unlisted label (NOT_FOUND, key left untouched) and a listed label (throws, key left untouched), using a temporary entitlements file.
• Without the change: the test does not link (undefined reference to sceNpEntitlementAccessGetEntitlementKey). With an unlisted label returning 0 it fails at line 59; with a listed label returning 0 instead of throwing it fails at line 68. Restored: passes.
• ctest -j8 -E "agc_driver|graphics": 262/262 passed.
• PPSA28997, relinked with feat(relinker): add --module-dir for modules loaded at run time #846 (--module-dir Media/Plugins --module-dir Media/Modules) and feat(libkernel): implement _umtx_op wait and wake operations #1482 (_umtx_op): all imports now resolve; the title starts, renders, mounts and writes its save data, and keeps running.

The progress report counts sceNpEntitlementAccessGetEntitlementKey as a stub because its body still calls NotImplemented_nid_no_patch. That call is only on the path for a label listed in the entitlements file, where AnyPS5 has no add-on key to return (recorded in TechnicalDebt). Null arguments and unlisted labels are implemented and covered by guest_np_entitlement_access. No change made for this report.

Correction: #1436 (opened earlier today) already adds sceNpEntitlementAccessGetEntitlementKey with the same signature, so this PR duplicates it. I missed it because my search only matched PR titles. I'll close this one in favour of #1436 unless a maintainer prefers this version.

One difference for whoever reviews #1436: it answers an unlisted label with 0x817D0007 and null arguments with 0x817D0002, while the rest of libSceNpEntitlementAccess on main uses 0x80558007 (NOT_FOUND) and 0x80558003 (PARAMETER), for example sceNpEntitlementAccessGetAddcontEntitlementInfo. It also doesn't look at the entitlements file, so a label listed there is reported as not owned by this function but as owned by GetAddcontEntitlementInfo.
