ApplyFastClear took the color fill before the CMASK clear, so a partial
fill of a multisampled target's color memory threw at the next use even
when a CMASK fast clear was pending over the whole target. The CB reads
a cleared tile's color from the clear registers whatever the memory
holds, so the CMASK clear is applied and the recorded fill dropped.
DecodeColorMetadataPass treated a CB_COLOR_CONTROL resolve as one only
when PA_SC_AA_CONFIG has a sample count, and checked the source against
it. A title that resolves with the rasterizer single-sample fell through
to the draw path and threw "only normal color rendering with copy ROP is
supported (... mode resolve)".
A color target's sample count is CB_COLOR_ATTRIB.NUM_SAMPLES, separate
from the rasterizer's; radeonsi itself writes PA_SC_AA_CONFIG 0 for a
multisampled framebuffer when rasterizer multisampling and line
smoothing are off. So a resolve is decoded when either the rasterizer or
CB0 is multisampled, and its sample count is CB0's. When the rasterizer
is multisampled, the source still has to match it.

A multisampled target's samples live only in its host image, so a fill
of its color memory never reached them: a title that clears its MSAA
targets that way (with no CMASK) kept drawing over the previous frame.
A uniform fill over the whole color memory now clears the host image to
that value at the target's next use, the same way a CMASK fast clear
does, and a pending CMASK clear still takes precedence. The color memory
is sized with addrlib's block dimensions for the sample count
(ComputeThinBlockDimension): a 64 KiB block holds width x height x
samples elements, laid out width first for 1x and 4x. A fill over part
of it, over a target whose footprint is not computed, or with a value
that has no exact clear value in the format throws at the next use.

The SPIR-V emitter declares extra views of the guest buffers binding:
buffers_coherent for GLC or DLC accesses (#2369) and buffers_u64 for
64-bit atomics. Each is another StorageBuffer variable on the same set
and binding, decorated Aliased, which Vulkan allows.
ShaderValidation, which checks the stages of every draw, accepted one
StorageBuffer variable per binding with u32 elements only, so such a
graphics shader was refused with "duplicate SPIR-V resource binding".
A second variable is now accepted when the binding is the guest buffers
array and every variable on it is Aliased; an aliased view may hold u64
elements. Other duplicates are still refused. agc_driver_graphics
validates pixel shaders with a GLC store and a 64-bit atomic, and checks
that the same modules without Aliased are refused.
The kernel reads its value with s_buffer_load_dword through the V# in
user[4..7] and stores it with buffer_store_format_x through the V# in
user[0..3]. When the value V# covers less than a dword (NUM_RECORDS
times its stride, or NUM_RECORDS bytes for stride 0) the load returns 0,
and a store format other than 32_UINT, 32_SINT or 32_FLOAT converts the
value, so in both cases the HTILE does not receive the dword read from
memory. The match now requires both. Kena's own dispatch (format
32_UINT, a value V# of one 16-byte record) still matches.

PPSA01802 (Kena: Bridge of Spirits) clears its depth HTILE every frame
with its own compute kernel: a 9-word dword fill that stores, through
the stride-4 V# in user[0..3], a value loaded from the pointer in
user[4..5]. Neither the DMA_DATA hook nor the fill kernels the driver
recognizes saw it, so the depth kept the first frames' contents and the
base pass and sky failed their depth test almost everywhere.
The kernel is matched exactly when the dispatch is decoded, the value is
read from guest memory, and the range is passed to NoteDepthMetadataFill
like a fill, so the whole-HTILE and ZMask rules apply unchanged.

Pipeline libraries take ownership of shader modules during prebuild. Treat null handles as a no-op so moved-from modules do not decrement the live-object count twice.
Apply the source-configured D_X XOR refusal during color decoding as well as direct layout construction. Regression tests reject each raw column-bit combination before storage or rendering is selected. Existing resident-array and packed-mip refusal paths remain in force.
AI-assisted implementation and validation: Codex.
Map SW_64KB_D_X color surfaces through the existing source-backed texture equations and mip geometry. Keep display and render-target equation caches separate. Reject unresolved raw column bits for the new mode instead of accepting them.
Cover the captured PPSA99902 descriptor, independent source offsets, pipe/bank tags, transfers, array/mip placement and resident/non-resident GPU draws. Record unmeasured console behavior in TechnicalDebt.
CPU validation on main e013f8c9: captured-descriptor failure 5/5; changed passes 5/5; pinned AMD addrlib reference 536940 addresses per run, five runs. Full build and GPU validation are tracked externally. AI-assisted implementation and validation: Codex.
With PA_SC_AA_CONFIG at one sample and MSAA_ENABLE off, the hardware scans
each pixel once and gives every sample of a multisampled color target its
result: radeonsi programs exactly this when GL multisampling is disabled on
a multisampled framebuffer (si_emit_msaa_config leaves sc_aa_config 0), and
GL defines it as single-sample rasterization with full coverage. Such a draw
without depth or alpha-to-coverage now rasterizes the target's sample count
with every sample location at the pixel center, which covers all samples
exactly when the center is covered.

Goat Simulator 3 draws a triangle list whose indices are all 0xffffffff
with primitive restart off. Each fetch past a descriptor's records reads
zeros (out-of-bounds select 0 or 1), but the zero-padded vertex copies
were sized to the highest index: 160 GiB, which vkAllocateMemory refused.
When the highest index is at least 64Ki vertices past the largest
per-vertex record count, the draw now uses a copy of its indices with
every index past that count moved to it. Each attribute reads zeros
there as at the original index; only the vertex index the shader sees
changes, so indices closer to the records are left as they are.

Vulkan's standard 8x sample 7 is (0.9375, 0.0625), (7, -7) in signed sixteenths; the table had (7, -8), so the
standard pattern (PPSA99902's PA_SC_AA_SAMPLE_LOCS words 0xbd153fd1 / 0x9773f95b) was refused as nonstandard.
Regression row with those words.

The duplicate ColorTarget::cmaskAddress, decode and size helper are gone: multisampled targets
use main's cmaskAddress/cmaskBytes (whole metablocks). Single-sample targets keep main's rule
(CMASK under FAST_CLEAR); a multisampled one takes it under FAST_CLEAR or COMPRESSION. A zero
fill of the whole CMASK clears at the next use, 0xFFFFFFFF marks it expanded, any other or
partial fill refuses the next use; eliminate/DCC passes over a multisampled target and a CB
resolve into a fast-clear destination are refused. The draw key adds CMASK_BASE_EXT (0x398),
which main decodes but did not key.

Draws with PA_SC_AA_CONFIG multisampling (2, 4 or 8 samples, every target with as many
fragments, the standard sample locations, MSAA_ENABLE) render into host-only multisampled
color images and multisampled depth surfaces; the pipeline rasterizes with that sample
count. A CB_COLOR_CONTROL resolve over a multisampled CB0 runs as a render pass whose
resolve attachment is CB1's resident image. A zero fill over a target's CMASK fast-clears
it to the CB_COLOR_CLEAR_WORD values of its next use. EQAA, coverage conversion,
nonstandard sample locations, sampling a multisampled surface and multisampled mips stay
refused.

A FLAT_SHADE input without pass-through that a pixel shader reads
through v_interp_mov_f32 P10 became an explicit per-vertex input and
read vertex 1 minus vertex 0. With the last provoking vertex the
pipeline then threw ("last provoking vertex with explicit per-vertex
flat interpolation is unsupported"), which stopped all three
ps5-opengl titles in the catalog.
ps5-opengl reads every flat input through P10 when GL's last-vertex
convention is in effect, and its driver passes the GL 4.6 CTS on a PS5
(#1413). Such a read now returns the provoking vertex's value, as P0
does, and only a P20 read keeps a flat input per vertex. The lane was
not measured on the console itself, so FragmentParameter records it
and a pipeline using the first provoking vertex throws.

A rect-list draw whose count is not a multiple of 3 threw "incomplete rect-list
primitive". Rect lists are drawn as patch lists of 3 control points, and Vulkan
generates floor(vertexCount/3) patches, so the draw now records as is and the
trailing 1 or 2 vertices are left out. Palworld (PPSA23126) draws 4 vertices x 9
instances as a rect list when character creation opens (#3832).

DecodeState bound the depth surface whenever DB_DEPTH_CONTROL enabled a
depth, stencil or depth bounds test and either plane was valid. A stencil
test beside a depth-only surface (DB_STENCIL_INFO format invalid, depth
test off) tests nothing, but the surface was still attached and the
render extent was clamped to it. A draw into a 1920x1080 target with a
960x540 depth surface left bound then covered only the top-left quarter.
A test whose plane is present but invalid no longer binds the surface.
Such a draw renders without a depth attachment, as it already does when
both planes are invalid. DrawRejection follows the same rule.
