A Windows import under 1 MiB returns to the write watch once its settle
read has completed, though main-queue work submitted before the read may
have used the import first, and an earlier import of the same pages may
not have run its first use yet. On the NVIDIA driver (617.42) neither
marks the pages once the read has completed, so the rewatch needs no wait
for the main queue. The docs said the marking lasts until the import's
first GPU use completes; they now say that a completed GPU use ends it,
the settle read included.
agc_import_settle_first_use submits 4096 copies of a 64 KiB import on
the main queue before its settle read is queued. The import must return
to the write watch while the copies still run, and the driver must mark
none of its pages afterwards.
agc_import_settle_earlier_import records 4096 copies of a 64 KiB window
import, replaces it with the import of its whole 128 KiB range, and
submits the copies only once the range is back in the write watch. The
driver must mark none of the range's pages while they run. A driver that
keeps marking fails either test.
Retiring a Windows import whose settle read was still running waited for
the read's batch under the imports mutex, so lookups on every thread
waited with it. The retired import is now kept with that batch and freed
once the batch has completed. Only a guest unmap of its memory still
waits for the batch, in the pin waiter, which waits for the main queue
there anyway.
The [buffers] profile line counts these retirements and the unmaps that
waited, apart from the imports of 1 MiB or more settled inside their
window, which the old wait counter mixed with the retirement waits.
agc_import_settle_retire replaces a 64 KiB window import with the import
of its whole range, 64 times, right after its settle read was submitted.
No replacement may wait, at least one must find the read running, and
the last import must return to the write watch.
ARCHITECTURE.md and the debt entry describe how imports under 1 MiB are
settled without waiting and return to the write watch, which the debt
entry listed as not implemented.
Use the registered application allocator and the source-backed alignment/size signature. Add callback ownership and failure checks; record unmeasured console behavior.
Git for Windows 2.56 (runner image 20261002) moved from mingw64 to ucrt64,
so the fixed SSL_CERT_FILE path no longer exists and the WinLibs CMake
fails the FFmpeg download with status 60 on every Windows build. Take the
bundle from whichever of ucrt64 and mingw64 exists.

A guest S# with FILTER_MODE min or max and an anisotropic XY filter
threw "combines a min or max reduction with anisotropic filtering",
which stops High on Life (PPSA15388) in its home base. It now decodes
to a Vulkan sampler with both anisotropy and the reduction mode, as a
weighted-average anisotropic S# already does. RADV programs the same
S# for such a Vulkan sampler.
Tamalero's gfx1030 measurement on #5156 covers a sample without
derivatives through a 2x anisotropic S# over a single-level texture:
min or max with anisotropic bilinear returns the bilinear minimum or
maximum, and min with anisotropic point the point result. The
execution test checks the bilinear case on the host GPU; the debt
entry records what is not measured.

Restore world-to-listener matrix construction instead of rejecting
non-default orientation, translation or flags.
- Build an orthonormal row-major matrix from position, orient_front
and orient_up; apply the right-handed axis flip for flag 1.
- Store the negated dotted translation in each matrix row.
- Validate unknown flags, invalid or non-finite input, short
orientation axes, and unrepresentable translation without changing
the output.
- Preserve finite velocity and positive finite sound speed.
- Update NGS2 geometry tests and the libSceNgs2 technical debt note.
