A read-only open, stat or reachability check of a missing path listed its
directory twice: once for a case-insensitive match of the name and again for
a case-insensitive match of the relinked <name>.guest.prx (#5434). Both
names are now matched in the same listing. Precedence and the ambiguous-name
errors are unchanged.
Since 39fdc48b5 a graphics program outside every registered shader was
read raw only while the registry was empty, and any RegisterShader after
the first raw draw threw. A title that registers some shaders through
sceAgcCreateShader and also draws programs it never registers stops at
its first such draw with "graphics program does not belong to a
compatible registered shader": oops-sdk homebrew registers its display
shaders while radeonsi (oops-mesa) submits raw programs.
Graphics programs now resolve as compute dispatches already do: an
address inside a registered shader resolves to that registration (a
registration of another type still throws), any other address is read
raw. RegisterShader throws only when the new shader's code overlaps a
graphics program that was drawn raw, where the program would get a
second identity (the draw cache revalidates raw programs by reading them
raw), instead of after any raw draw.
The drawn range is recorded once per raw snapshot: a flag on the
snapshot keeps later decodes of the same program off the lock. Recorded
ranges are merged, so the overlap check looks only at the predecessor of
the queried end.
Tests: agc_driver_prepared_graphics (a draw whose programs are registered
as compute shaders is refused, where it used an address outside every
registration before), agc_driver (ProgramSnapshot reads raw beside registered shaders
and refuses a registered program of another type; nested, overlapping
and adjacent raw ranges), agc_driver_prepared_unregistered_graphics
(raw-drawn ranges recorded exactly, unrelated code not reported).

Its declaration sat right after ClearCachedTextures, where another open change adds a line too. It now follows SampledBudgetReportDue, with the other memory-budget helpers.
DeniedParentWatch denied FILE_LIST_DIRECTORY to the name GetUserNameW
returns. When the user name equals the computer name, LookupAccountNameW
resolves that bare name to the computer's domain SID (SidTypeDomain), so
the deny entry matched no one, the parent watch was allowed and the test
aborted on an empty error. The entry now names the SID of the process
token's user.

When the current pool filled, the search for a completed pool started after it and skipped it, so a
title whose batches had all completed got a new pool instead of resetting the full one. The search
now ends at the current pool. A detiler test fills three pools' worth of sets with no batch in
flight and requires the pool count to stay the same.
TextureDetiler reset its descriptor pools only when the recorder was idle, so a recorder that keeps
work in flight grew a 64-set pool for every 64 detiles until vkAllocateDescriptorSets failed with
VK_ERROR_OUT_OF_DEVICE_MEMORY. PPSA25344 with its title near 9 FPS stopped on that after 12 and 22
minutes. Each pool now keeps the serial of the newest batch that used one of its sets, and a pool
whose batches completed (Recorder::CompletedThrough) is reset and reused before a new one is
created. The texture, image and CMASK pools share that ring.
Requests replayed from versions 22 to 24 now re-serialize at version 29 with
the default quad pixel mask (0xf) and quad sample masks (0xffff) after the dither and front-face flags, plus the empty linked call fallback list.
ReadFirstLane, Ballot and PermuteU32 can consume uncovered helper lanes after a fragment explicitly enables EXEC. Classify those operations as neighbour reads so a partial quad mask refuses their kill fallback when demote is unavailable. ReadFirstLane also stays protected when a constant whole-quad instruction folds away.
The CPU regression covers explicit EXEC, constant WQM, a comparison ballot and ds_permute. Unmasked programs still compile, supported masked programs retain demote and their subgroup operation, and constant colour keeps the kill fallback. The recovered source fails the readfirstlane and ballot checks; the corrected source passes both the focused check and shader-memory suite.

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.
With PA_SC_AA_MASK covering only some pixels of a quad, the uncovered pixels
run on the hardware as helper lanes, so derivatives of the covered pixels stay
defined. OpKill ends those invocations; OpDemoteToHelperInvocation keeps them
as helpers. The device enables VK_EXT_shader_demote_to_helper_invocation when
available and passes the DemoteToHelperInvocation capability and its SPIR-V
extension to the recompiler target and the graphics shader validation. A
demoted pixel also reads as a helper, so its initial EXEC bit is clear as on the
hardware. Without demote, OpKill stays for pixel programs that read no
neighbouring lanes; implicit-LOD sampling, LOD queries and cross-lane reads are
refused. The quad pixel mask execution test now also samples a mipmapped
texture with implicit LOD under the mask.
With one sample, PA_SC_AA_MASK leaves one coverage bit per pixel of the 2x2 quad,
so a draw can cover only some pixels of every quad (GTA V renders a target one
quarter of the pixels at a time this way). The pixel stage info carries that 4-bit
mask; a fragment shader whose mask is not full starts by killing the invocation
unless its gl_FragCoord quad position is covered, and runs without early fragment
tests. The mask is part of the recompile cache key and the serialized request
(version 24). Sample masks of multisampled draws stay refused.
Reject native sampled views of the depth image attached by the same draw before pipeline creation. Keep unrelated views, other devices and the single-sample path unaffected. Add unrun native-view refusal and scope controls; full dependency-stack build and runtime validation remain pending.
Adapt our preserved native-depth sampling work from c0d9edf and sample-aware footprint work from 6e35a877, retaining creation-time coherence and initial HTILE proof. The descriptor interface in upstream PR 4820 remains a separate prerequisite. This source draft has not been built or run.
