What

Implements 22 system-library functions on top of current main, raising coverage from 2973/3449 (86.20%) to 2995/3449 (86.84%) with no denominator change. Includes the sceKernelGetEventError fix (FreeBSD EV_ERROR semantics). Every function follows an already-accepted in-repo model with a focused test:

• libkernel (1): event-error via EV_ERROR flag, null-checked like siblings
• libSceNpEntitlementAccess (2), libSceNpSessionSignaling (4): offline SIGNED_OUT/UNAVAILABLE errors, like same-file siblings
• libSceGameUpdate (1), libSceNpManager (2): null/id validation mirroring identical-signature siblings
• libSceShare.native (4) + libSceShare (1): accepted no-capture model (+test/CMakeLists for native)
• libSceIme (1), libSceNet (1, synchronous-resolver abort no-op), libSceSystemGesture (3), libSceAudioOut (1), libSceNpWebApi2 (1)

Rebased onto current main; yielded SigninDialog, Http epoll work, and 4 entitlement queries to upstream implementations. NpAuth (3) and NpPartner001 (2) removed in favor of open #3604 and #3718; rebase planned after they merge. Supersedes #4046, which could not be reopened after the rebase force-push.

Unverified on console and disclosed: gesture/share codes (in-repo precedent only), abort/accept semantics.

Tested

• python3 tools/check_conventions.py --base 43bc17f --head HEAD -> pass
• python3 -m unittest discover -s tools/tests -> 174 tests OK (2 skipped)
• python3 tools/progress.py -> 2995/3449 (86.84%), +22, no regressions; shaders 1166/1166
• Full cmake build, ctest, guest tests: not run - no toolchain (no cmake/compiler, submodules uninitialized). Requires a configured runner before merge.

Checklist

• Based on current main; no other open PR implements the same functions
• One topic per PR; follow-ups go in a new PR
• No comments in code except technical debt
• Unimplemented paths throw (NotImplemented_nid_no_patch); silent stubs are listed in TechnicalDebt
• No notes, investigation .md files or images added to the repository
• New third-party code is a submodule built from source
• Generic behaviour, not specific to one title
• Depends on: none
• AI-assisted: yes

One question about sceNpSetContentRestriction: this currently returns success for both null and non-null restrictions, but the restriction is opaque (std::uint8_t opaque[128]) and doesn't appear to be stored or enforced anywhere in the library. Since the libSceNpManager model reports the user as signed out when PSN isn't emulated, could unconditional success mislead a guest into believing the restriction was applied?

The neighboring NP APIs generally validate null pointers and return an NP error when the service is unavailable — sceNpGetAccountAge and sceNpGetNpId both check their pointer and then return SCE_NP_ERROR_SIGNED_OUT.

I don't have console measurements for this function, so I'm raising this as a consistency and guest-visible-behavior concern rather than claiming the exact return code is known. Would it make sense to document the no-op behavior explicitly, or to use the existing signed-out error convention?

Closing: this removes the throw from 22 exports in 12 libraries to raise the progress figure, none of them is tied to a title, and by the description it was never built or run. Please reopen one library at a time, built and tested, with the title that stops at the function on main.
