An image table cannot store, update atomically or read PCK and BY2/BY4
through its records (#757): those operations fault and read zeros. #6243
turns a heap T# whose words and record offset the SRT walker evaluates
into a selected one-record table, which kept that limitation although
such a T# is one known descriptor, as #5188's direct images were.
PlanTableColumns now binds such a T# directly, for every operation of the
shader on it, when any of them is a store, an atomic, a packed or a
BY2/BY4 access. A T# keyed per lane, or by a value the walker cannot
evaluate, keeps its table and its unsupported-operation fault. The disk
format moves to 37 so that plans cached by #6243's builds are not reused.
Since #757, a T# loaded from a buffer heap at a runtime offset is an
image table column, and every capture snapshots the whole heap, up to
65,536 records, even when user data or an SRT read fixes the offset.
When the T#'s eight dwords and its offset are runtime values the SRT
walker evaluates, the column is now selected: the offset is kept as a
descriptor source, the shader indexes entry 0, and the snapshot reads
only the record at the evaluated offset, with the heap base moved to
that record.
The column keeps a table's semantics. An invalid T#, an unmapped record
or an offset that carries past 32 bits is poison that faults only when a
lane selects it; an offset the walker cannot read faults the table
instead of throwing; the record's mode is picked per entry, so no
pipeline variant is added; and a dispatch that writes the record faults
it as written by its dispatch. Dwords past the heap read zeros, as the
scalar loads would, and a record past the key cap is read rather than
poisoned.
A column stays a whole table when its offset is chosen per lane, or when
the shader may write the memory the offset is read from at run time: the
buffer it is read from (by V#), or any memory when the read or a write
goes through a pointer or a GPU-only descriptor. Samplers are unchanged:
an S# the walker evaluates is already a direct sampler. The plan stores
the selection, so the disk cache format is 36.
Five agc_shader_memory and agc_shader_bindless checks asserted the old
planning and now assert the selected record:
- "image table SRT key": a key read through the SRT narrowed a 4-key
table to records 0 and 2. It now selects record 2 alone, captures no
other record, and a changed key moves the capture without changing the
module or its disk key.
- "image table key union" and "image table late key": two keys of one
heap shared one column with two value key domains. Each key now
selects its own record, as two one-record tables.
- "image table unkeyed access": a read keyed through the SRT shared a
whole column with a read keyed per lane. The first now selects its
record; the second keeps the whole, unnarrowed table.
- "uniform table image": the T# at a user data offset was one key of a
full table. It is now the one selected record, and the record the user
data does not select is not read.
A value key domain only arises for a key the walker evaluates, so it no
longer narrows an image column; key buffer domains (keys loaded per
lane) still do.
Decode the four PA_SC_AA_MASK fields at the rasterized sample count. Use the native Vulkan mask when all four pixels agree and apply varying masks in the fragment shader, preserving helpers and combining coverage with alpha-to-coverage and shader mask exports. Add the normalized masks to pipeline, draw and shader keys and the versioned replay request.
Refuse unsupported conservative-raster, centroid and early depth/stencil memory-write cases. Synthetic readbacks cover driver submission, depth/stencil suppression, fragment stores and one-sample and four-sample coverage.
A dump is fully installed, so scePlayGoGetSupportedOptionalChunk and
scePlayGoGetOptionalChunk report every optional chunk (language pack) like
scePlayGoGetLanguageMask reports every language. They returned an empty
bitmask, so PPSA01748 hid every text language its playgo-scenario.json
lists as a chunk language, English included.

A 2D image_sample_l through a 1D T# now takes the 1D runtime mode, as
image_sample_lz already does, instead of failing the runtime image
interface. Measured on RDNA2 (gfx1036) with tools/hw-oracle against the
same sample with DIM 1D: u inside, on and past the edges, v of 0, 0.5, 1,
-0.25 and 3, LOD -1 to 6 on a 5-level R32_FLOAT texture, point, linear and
linear-mip filtering, wrap, clamp and border addressing, and HEIGHT or
DEPTH 3. All 4725 rows matched: the 1D T# decides the addressing and v is
ignored.
The execution test samples a 5-level 1D T# with distinct mip contents at
LODs -1 to 6, fractional ones included, with u inside, on and past the
edges, under point filtering with wrap and clamp and linear filtering with
linear mips and wrap, clamp and border addressing. Every result must match
the same image_sample_l with DIM 1D bit for bit; point-filtered results
must also be the expected texel of the expected level, and linear-mip
results the blend of the two levels the LOD selects.
On Windows every direct host import leaves the write watch, and a sampled
texture snapshot over it was compared with guest memory at every lookup:
its generation stays 0, so UnchangedSince never holds. ASTRO BOT
(PPSA21564) compared about 31 GB per 10 s at the title.
The lookup now keys such a snapshot by UntrackedHint, NewestStamp,
ForgetSerial and the recorder's newest write note, taken before the
snapshot is read or compared, as StorageTexture::compareUntracked does,
and skips the compare while the key is unchanged and no recorded work
writes the surface. The byte compare still decides after any mark.

Crimson Desert (PPSA25286) calls scePadSetVibrationMode(handle, 5)
at start-up, and main rejects any mode above 3 with
SCE_PAD_ERROR_INVALID_ARG (0x80920001). The title then carries on
with the call failed.
The modes are not documented. SharpProspero names 1 (advanced) and 2
(compatible); mode 3 was accepted for PPSA21480. The call now also
accepts 5, which a shipped title passes, and keeps rejecting the values
no title has been seen to use (4, 6 and above). The mode is stored as
before and has no other effect.

ds_add_f32 and ds_add_rtn_f32 now follow the measured hardware: both
operands are flushed to a signed zero when bit 0 of the f32 denormal field
is clear and the result when bit 1 is clear, the sum is rounded to nearest
even, a NaN data operand is stored quieted, else a NaN old value is stored
quieted, and +inf + -inf stores 0xffc00000. Measured on gfx1010 and, in
#5492, on gfx1031.
The new MemoryInfo field is stored in the shader disk cache (field count
31, minimum record 79 bytes, FormatVersion 34). The parts that depend only
on the data operand are computed once, before the CAS loop.

The Windows error for a refused FindFirstChangeNotification was one string shared
by WatchParent and WatchContents, so the log could not tell which handle or path
was denied. Build it from the watcher, the path the API was given and
GetLastError instead.
Still throws: the EVFILT_VNODE attach path is vfs_kqfilter, which returns only
EINVAL, ENOMEM or 0, with EBADF from fget before it, and consults no directory
permission, so no FreeBSD errno stands for a host that refuses to notify.
Main's flatVolumeLineCompatible change also took format 34 with another layout, so entries of either would load as the other.

Move bounded vertex folding and empty-image feedback into separate topics. Keep the replay coverage proof, stage contracts, finite-reference tests and mapped cache regressions; version the stencil layout separately as format 34.

Preserve instance and triangle order with one dynamic-reference shader pipeline. Require bounded references, complete export coverage, replay-safe mask control and resources; refuse unsupported side effects and feedback.
