The blocked-destination case checks a different file, so an in-place
rewrite passed it. The earlier case is back beside it: a directory at
<name>.tmp makes the write fail, and the previous aps5-bench.json.gz must
be unchanged. It is left out of Windows builds, where the
std::ios_base::failure thrown inside the MinGW ofstream did not unwind to
the test's catch.

Without VK_EXT_shader_stencil_export (NVIDIA), stencil reference exports
are emulated by replaying the draw once per value. An export the prover
could not bound to at most 16 values was refused. The replay shader
compares the export's low eight bits, so an unbounded export now
replays all 256 values, and proven values are reduced to their low
eight bits as the comparison sees them.

Over budget but within a quarter over it, the sampled texture cache refused no use of a texture it does not hold, so a cyclic scan over a working set larger than the budget rotated the whole cache and hit almost never. The first use of a key in a present is now refused (used for its draw, never cached) when the least recently used entry was used in this or the previous present. A later use of the key is refused only when that entry was used in this present, so a texture used several times per present is still admitted on a later use. The refusal does not apply past the quarter-over ceiling, so a budget that falls still evicts.
The test lowers the budget through OverrideCacheBudgetForTest instead of the environment. The debt entry records the unmeasured present window, that a texture used more than once still rotates the cache, and the one A-B-A measurement.

When the list read at submission is invalid, the worker now always
executes the copy read again where the packet runs. With
APS5_SKIP_INVALID_INDIRECT_REGISTERS=1 only that copy's invalid entries
are skipped, so the valid entries of a partly updated list are written
instead of the stale ones from submission.
testPartlyUpdatedRegisterListSkipsOnlyItsInvalidEntries submits a list
that is invalid at submission, updates it to a valid entry plus an
invalid one before its packet runs, and reads the register back with
COPY_DATA.
SET_*_REG_INDIRECT lists are read when the command buffer is submitted.
When that copy holds an offset dword that is no register offset, the
queue worker now reads the list again where the packet executes (as the
console PFP does) and uses that copy if it is valid.
PPSA23566 (UFC 6) intermittently submits a SET_CONTEXT_REG_INDIRECT
whose first entry is 0x038f038f or 0x03900390 in both copies, followed by
180 valid pairs, and the title stopped with "extended register semantics
are not implemented". With APS5_SKIP_INVALID_INDIRECT_REGISTERS=1 the
invalid entries are skipped and the other registers are written; without
it the packet throws as before.
A pixel shader on the mesh path that reads barycentrics on a device with
neither VK_KHR_fragment_shader_barycentric nor VK_EXT_mesh_shader
reported only the missing mesh shaders. Say that the device has neither,
so reports from such devices are told apart from the case the emulation
covers.

A pixel shader that reads barycentrics on a device without
VK_KHR_fragment_shader_barycentric used to need a vertex shader so a
generated geometry stage could follow it, which a mesh pipeline cannot
have. The mesh program is now compiled a second time with the layout
its pixel shader needs: it writes its clip position as a varying and the
three corner positions of each primitive as per-primitive outputs, and
the pixel shader solves for the weights, for both smooth and linear
interpolation.
The layout is part of the mesh cache key, the stored artifact and the
captured request. Without VK_EXT_mesh_shader the draw still throws, now
saying so. Per-vertex parameters on the mesh path still throw.

Results that land in a unit whose store ran while its blocks were
watched, after those blocks left the watch while nothing was pending,
have neither saved bytes nor a watch: the unwatch hook found nothing to
save and the write-back refuses as before (#7017). The entry named only
the range that leaves the watch without the hook running over it.
A MarkWritten whose fresh collect fails (a no-access or unwatchable
resident page inside the 64 KiB block span) took the span out of the
write watch without running the unwatch hook, so pending storage-image
results over it kept no saved guest bytes and their write-back refused:
storing storage image results pending over memory outside the write
watch without the guest bytes saved before them is not implemented
(#7017, Palworld PPSA23126 among others).
The hook now runs over the block span before the blocks leave the
watch, as Unwatch and the import fallback do, with the tracker lock
released for it like #6308 does for imports. The debt entry drops the
failed collect from the unsaved cases.
The check makes a collect fail over a no-access arena page and requires
the hook to have covered the block; it needs the WindowsMappings
protection failure, so it runs in the Windows-only section of the write
tracking test.
