What

Resident Evil 4 (PPSA07411) imports seven PS VR2 calls that no library exports; #3537 adds other calls of the same family but not these. This PR declares them without parameters as throwing stubs (signatures unknown), as #1347 did for PPSA01317:

Library	Exports
libSceHmd2	sceHmd2GetDeviceInformationByHandle, sceHmd2GetFieldOfView, sceHmd2Terminate
libScePad	scePadVrControllerSetVibration, scePadVrControllerSetVibrationMode, scePadVrControllerReadCombinedState
libSceVrTracker2	sceVrTracker2ResetLocalCoordinate

Names come from the aerolib NID list (tools/nid_names.py). No test is added, since CONTRIBUTING says not to test that a symbol is exported; a TechnicalDebt entry lists the stubs. Overlap with #3537, checked with gh pr diff 3537: it declares sceHmd2GazeGetResult, sceHmd2Reprojection{DisableMirroring,EnableMirroring,GetMirroringDisplayBufferSizeAlign,GetMirroringWorkMemorySizeAlign,SetMirroringOption,SetParam,SetTiming,Terminate}, scePadVrControllerGetTriggerEffectState, scePadVrControllerSetTriggerEffect(s), sceVrTracker2Finalize, sceVrTracker2GetPlayAreaOrientedBoundingBox and sceVrTracker2LocateCoordinateSystem; none of the seven names here (main has sceHmd2GetFieldOfViewWithoutHandle but not sceHmd2GetFieldOfView). Both PRs append to the same three Export.cpp files, so they can conflict textually; this PR therefore inserts after the first function of each file. The title's other missing imports are covered by #3773 (Ssl, Json, ConvertKeycode, NpSessionSignaling), #3737 (Json setSpecialFloatFormatType), #3707 (libSceNet) and #3537. Each stub is added after the first function of its file, away from the end where #3537 appends.

Tested

• Windows, MinGW GCC 15.2.0: libSceHmd2, libScePad and libSceVrTracker2 build (on a base from before this rebase, with fix(libkernel): restore Windows select build for Demons Souls testing #4021 applied for the unrelated Windows HostPoll build break of the current main); tools/check_conventions.py --base upstream/main passes after rebasing onto main. I searched the open PRs for these names and found none.
• The RE4 import audit on a stack of main plus feat(libs): declare the PS VR2 exports PPSA15878 imports #3537, feat(libSceJson2): implement InitParameter2 constructors #3737, feat(exports): implement three small PRAGMATA exports #3791, fix(libSceNpTrophy2): accept a null details or data in GetTrophyInfo and GetGroupInfo #3517, feat(libSceNpAuth): implement offline auth requests #3604 and feat(libSceNet): export sce_net_in6addr_linklocal_allnodes #3707 lists exactly these names (together with the ones in fix(exports): export the calls PPSA07411 imports #3773) as the remaining absent imports.
• Not tested: running PPSA07411 with this change; the stubs throw.

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 (attach them to this PR)
• New third-party code is a submodule built from source
• Generic behaviour, not specific to one title
• Depends on: none (no shared names with feat(libs): declare the PS VR2 exports PPSA15878 imports #3537; possible textual conflict only)
• AI-assisted: yes (Claude Code)

Other open pull requests touch the same code. Merging one will break the other, or both implement the same thing. If this one builds on them, list them in Depends on.
