sceAgcSetAmmSemaphoreMemory(memory, sizeInBytes) registers the AMM semaphore memory once and zeroes the first 8 bytes of each 32-byte label; sceAgcGetSemaphoreLabel(index, label) writes memory + 32 * index for an index inside the registered memory.
Unblocks New Joe & Mac Caveman Ninja (PPSA02801) which imports both symbols. Matches OpenAGC and sharpemu agreements on signatures, 16 KiB alignment, 32-byte stride, and zeroed label counters.
Report the 8-byte GS primitive payload when the shader's context registers
set SPI_SHADER_IDX_FORMAT.IDX0_EXPORT_FORMAT to SPI_SHADER_2COMP, and 0
otherwise. The search runs over every context register, so an earlier
SPI_SHADER_IDX_FORMAT entry with another format does not end it.

sceAgcDcbSetWorkloadStreamInactive and the three ACB workload builders
(sceAgcAcbSetWorkloadsActive, sceAgcAcbSetWorkloadComplete,
sceAgcAcbSetWorkloadStreamInactive) threw for every call, and
sceAgcDcbSetWorkloadsActive read the workload ids before it checked the
stream.
The prosper console oracle (mattias800/prosper df074498,
prosper/tests/data/console_oracle/agcbuild.golden.tsv lines 48-56 and
196-204) measured all six calls on a PS5 with three argument patterns
and no workload stream registered: each returned null and wrote nothing.
Pattern b passes stream 1 with the workload ids at address 2, so the
console checks the stream before it reads the ids; here that call read
address 2 and crashed.
The four builders now return null for a null command buffer or a stream
that is not registered, and still throw for a registered stream: the
packet a registered stream gets is not measured, KytyPS5 has no body for
them, and its IT_NOP layout for the DCB calls differs from the
SET_UCONFIG_REG, WRITE_DATA and SET_WORKLOAD sequence OpenAGC
(3c7e8072, src/agc_workload_packet.c) derives from the driver. The
signatures are OpenAGC's DCB ones (src/game_compat.c), which says the
ACB calls use the same driver builders. sceAgcDcbSetWorkloadsActive now
checks the stream before the ids, as OpenAGC does. Recorded in
docs/dev/debt/libSceAgc.md.
agc_commands gains testWorkloadStreams: the three measured patterns for
all six calls (null, buffer untouched), an exhausted and a null buffer,
and a registered stream that throws without touching the buffer. On
upstream/main it fails with "sceAgcDcbSetWorkloadStreamInactive not
implemented", and the DCB active pattern b alone segfaults reading
0x2.

sceAgcDcbSetWorkloadsActive writes an 18-dword IT_NOP packet (stream id, 64-bit workload mask) and sceAgcDcbSetWorkloadComplete a 12-dword one (stream id, workload id, 64-bit clear mask), following KytyPS5. Both return null for a null buffer, an unregistered or out-of-range stream, a workload id above 63, and for active a duplicate id or a count of 0 or above 63. sceAgcDriverRegisterWorkloadStream and sceAgcDriverUnregisterWorkloadStream now record the stream ids the DCB calls check.

sceAgcDcbSetWorkloadsActive and sceAgcDcbSetWorkloadComplete threw. They now write a plain two-dword NOP and keep no workload state.

Hollow Knight Silksong (PPSA12544) imports libSceAgc NID vieBRwlh1Lw
(#699). Its name is unknown: it is not in aerolib, and the
sceAgcUpdateInterpolantMapping label other projects give it hashes to
SbuY2jN+axQ.
OpenAGC (src/game_compat.c at 3c7e807, sceAgcUnknownVieBRwlh1Lw) reads
it from FW 11.60 as the dbOlWdppb4o transform with the same (regs, gs,
ps) arguments, without the identity tail: it writes one register per
pixel shader input, none for a pixel shader without inputs, and rejects
a null pixel shader. It now shares the dbOlWdppb4o path and throws for
the rejected arguments.
For is_f16 1 and 3 inputs whose default_value and default_value_hi
differ, OpenAGC takes DEFAULT_VAL from default_value_hi, while KytyPS5,
sharpemu and dbOlWdppb4o here take it from default_value; these inputs
throw. On every other input the dbOlWdppb4o values equal OpenAGC's.
agc_interpolant_mapping runs the dbOlWdppb4o vectors and OpenAGC's
enhanced-mapping vectors through it.

EVO Player (PPSA99039), Jelly5 (PPSA99505), Emby5 (PPSA99515) and
Nuvio PS5 (PPSA99997) stop on main 0f863c10 with
what(): sceAgcCreatePrimState: invalid user configuration register offsets
All four build their shader headers by hand (EVO-PLAYER-PS5
evo_agc_shader_header.c, ported from ps5-xash3d-halflife) and store the
ge_user_vgpr_en special at 0x25c (GE_USER_VGPR1, value 0) instead of
0x262 (GE_USER_VGPR_EN), as analysed in #3457. They run on the console.
OpenAGC's reconstruction of the FW 5.50 sceAgcCreatePrimState
(src/game_compat.c at 3c7e8072) copies the four special register pairs
verbatim without checking their offsets; KytyPS5's offset checks
(src/libs/agc.cpp at 16a7fe68) are EXIT_NOT_IMPLEMENTED guards. The
special is now copied at the offset the header stores, not moved to
0x262; the driver reads neither register. GE_CNTL, VGT_SHADER_STAGES_EN
and a used VGT_GS_OUT_PRIM_TYPE are still required at their own
offsets because the driver reads them there, and the error now names
the special and the offset found.
With the change all four titles get past sceAgcCreatePrimState and stop
in the shader recompiler (GetImageResource dword 3 is not a valid
runtime value), as #3457 reported for EVO Player.

(cherry picked from commit aeaa5080d9595305aa73e74d966f989c88b79839)
sceAgcDebugRaiseException (NID T6xuVw0KUJo) now logs the exception id
with APS5_LOG_OUT and returns 0, as libkernel's
sceKernelDebugRaiseException does.
Palworld PPSA23126 (#2598) and 007 First Light PPSA11386 (#2523) import
it; neither is shown calling it.
OpenAGC 3c7e8072 (src/game_compat.c) returns 0 and says the function is
a no-op on retail hardware; the ud2 trap it describes for development
hardware is not reproduced. KytyPS5 6f0cddd4 (src/libs/agc.cpp) takes a
uint32 exception_id, logs it and returns 0. OpenAGC declares no
arguments, but a body that only traps reads none, so the uint32 is kept
and the conflict is recorded in TechnicalDebt. The aerolib name is from
zecoxao/sce_symbols 2883963a; ps5-payload-dev/sdk f5d40f02 has only an
untyped stub.

The builder threw on a null indirect base, while the PM4 executor accepts
SET_BASE with address 0 (it only requires the alignment and address bits) and
an indirect draw that later reads the base is checked there. Titles clear the
base with 0, as with sceAgcDcbSetIndexBuffer, which already accepts 0 to
unbind. A non-null base is still checked for 8-byte alignment.

#1629 makes sceAgcDcbResetQueue throw 'unsupported op bit 0x40' (and for
0x200/0x400). Dreaming Sarah and Astro Bot call it with op bit 0x40 at
start-up, so both abort before the first frame. Main with only #1629
reverted runs Dreaming Sarah normally again (59.9/59.9 fps, no skipped
draws, no flashes).
sceAgcCreatePrimState only packs registers, but it now also resolves the
graphics ABI ahead of time, and that resolve throws when the primitive
type is a patch list without HS_EN or a hull stage with another type.
No draw can use such a state, so leave it to draw time and return the
registers. Bit 2 of VGT_SHADER_STAGES_EN is HS_EN, not an NGG bit.

Replace the CLEAR_STATE approximation with the envelope and per-op-bit packet groups measured on PS5 firmware 13.60. Emit groups for op bits 0x001, 0x002, 0x004, 0x008, 0x010, 0x020, 0x080, 0x100 and 0x800 in ascending order; throw for 0x040, 0x200 and 0x400 whose packets the driver rejects. state 2 sets the envelope flag and state 3 sets the 0x004 and 0x800 group payload dword.
