 - [sceAgcAcbWaitUntilSafeForRendering](../../../core/libs/prx/libSceAgc/Acb/src/Control.cpp) (libSceAgc) - `(buffer, videoOutHandle, displayBufferIndex)`, the declared arguments, which PPSA12544 (01.000.010) passes inside `waitUntilSafeForRendering` and `waitUntilSafeForRendering VR` markers on an asynchronous compute command buffer, ignoring the result. It writes the same rendering-wait packet as `sceAgcDcbWaitUntilSafeForRendering`, which the driver now accepts on compute queues too; the wait blocks only that queue's worker. Whether the console encodes the compute variant differently is not known
 - [sceAgcGetDefaultCxStateFlat](../../../core/libs/prx/libSceAgc/Misc/src/RegisterDefaults.cpp) (libSceAgc) - copies up to `size` bytes (clamped to 2048 bytes, the 512-dword `AgcContextState`) from the default context state initialized from the version 8 public register default groups (CX, SH, UC), indexed by register offset, following OpenAGC `src/context_state.c`; returns `0x80890001` on null destination; version selection without `sceAgcInit` is unverified

+- [sceAgcSuspendPointAndCheckStatus](../../../core/libs/prx/libSceAgc/Export.cpp) - this named callable export is listed in the [PS5 3.20 export table](https://github.com/DNNDHH/PS5-3.20_Libs/blob/b2a77c09cd71c01f34c790cfbe98c751a13262ad/libSceAgc.c) and was cross-checked against the same module in PS5 firmware 13.60. Its signature and behaviour are unverified; the declaration uses the no-parameter unknown-signature convention and throws through `NotImplemented_nid_no_patch`.

 - [sceAgcDebugRaiseException](../../../core/libs/prx/libSceAgc/Misc/src/Debug.cpp) (libSceAgc) - logs the exception id and returns 0, as retail hardware does nothing per [OpenAGC](https://github.com/OpenAGC/OpenAGC/blob/3c7e8072f0d7684e930454794fd5c02056946d73/src/game_compat.c); the trap (`ud2`) OpenAGC describes for development hardware is not reproduced. Neither is verified on a console. The `uint32` exception id is [KytyPS5](https://github.com/KytyPS5/KytyPS5/blob/6f0cddd4404ec5203e71fea77e75fc373299ba3f/src/libs/agc.cpp)'s claim; OpenAGC declares no arguments, so the logged id may be leftover register contents
