sceAgcSetStaticBuffer, sceAgcGetStaticBuffer, sceAgcSetStaticQword and
sceAgcGetStaticQword read and write the six 16-byte slots at 0xfe0040000
that the driver already maps for the fetch shader table, through a new
AgcDriverStaticTable_nid_postfix accessor.

Write the INDEX_ATTRIBUTES_INDIRECT packet the console's builder writes,
as measured by the prosper console oracle, with OpenAGC's signature, and
report its measured size of 16 bytes.

On Windows, agc_shader_helpers returned from main with the driver's
threads still running. ExitProcess ends them first, then the DLLs'
static destructors run and wait on what those threads left locked:
the async log's queue mutex in Driver::stop, DeviceUseGate's condition
variable in ~Driver, and condition variables in libkernel's statics.
The test hung after printing its result in about one ctest run of
three on a Radeon 860M (#6791).
Like the other driver tests, it now runs LibcRunShutdown_nid_postfix
before returning, which stops the driver while its threads are alive.

Reads the root at its byte offsets, walks the type table as key and
bank-index pairs and checks that the MRT0 key leads to the sixteen
colour-target registers: block 78 of the table sceAgcGetRegisterDefaults
returns, block 73 of version 10, and a valid block in every version from
4. Fails on the compact entries and on the version 0 legacy table.
sceAgcCbSetShRegistersDirect and the other register list writers threw on
a count of 0 although the matching size functions report 0 words for it.
PPSA05684 calls the writer with an empty list at its main menu and
terminated. An empty list now writes no packet and returns the cursor,
as its size says; a null buffer still throws.
AI-assisted: yes
The names hash to the NIDs dbOlWdppb4o and vieBRwlh1Lw that the exports
carried as sceAgcUnknownCreateInterpolantMapping and
sceAgcUnknown_vieBRwlh1Lw.

sceAgcFuseShaderHalves copied both halves' code, the fused header and its
tables into the caller's memory and registered the program at that
address. PPSA02100 fuses different halves into the same memory a few
calls apart, while draws that use the earlier result are still queued.
The registry keeps one program per code address, so those draws were
compiled from the later program: its code read a user-data word the
bound layout does not have, and the device reported "BDA access failed"
for the mesh stage.
The PS5 5.02 module writes only the back half's register list into that
memory (sceAgcGetFusedShaderSize reports eight bytes per register,
alignment 4) and leaves the code where the halves are.
The fused code, header and tables now live in memory libSceAgc owns, one
program per distinct pair of halves, registered once. The caller's
memory receives the fused register list and the size query reports that
list. A second fusion of the same halves returns the same program; halves
whose contents changed get a new one.
The driver looked a header up by comparing its fields with the
registered header, including the register list's address. A header whose
register list is a copy elsewhere with the same contents now matches
too, which is what the title passes after a fusion.
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.
