An EOP flip reservation also ended a frame, and so did the submission
whose EOP release carries the reserved token, so a title flipping with
EOP releases counted each displayed frame twice: a capture of N frames
stopped after about N/2 and could start between the reservation and
the submission that flips. The reservation is now only recorded; a
frame ends at a CPU flip or at a submission that flips.
agc_driver_frame_capture_eop reserves and submits six EOP flips with
APS5_FRAME_CAPTURE_FRAMES=3 and checks that the capture starts after
the first flipping submission and holds three frames of one reservation
and one submission each.

APS5_FRAME_CAPTURE=<dir> makes the AGC driver record a few frames of a
title: the shader registrations and ABI resolutions, video output and
EOP flip reservations it made since it started, a snapshot of every
readable guest allocation (the title image included) taken at a frame
boundary once the driver is idle, and for the next frames each
submission, flip and suspend point with the thread that made it, its
serial progress and the guest pages the write tracker saw the CPU write
before it. At the end it stores the presented display buffers as
reference images. APS5_FRAME_CAPTURE_AT_FLIP, _TRIGGER and _FRAMES pick
the frames.
agc_frame_replay maps the captured memory at its addresses and replays
the calls of each captured thread on a thread of its own, in captured
order, through the current build of the driver with no title running.
It paces GPU work to the in-flight depth the title had, releases GPU
waits that the title's CPU threads released without calling the driver
(AgcDriverAwaitedWaits), and reports frame times, released waits and
how closely the replayed display buffers match the references.
Tests: agc_frame_capture (file format) and agc_driver_frame_replay
(two captured frames of CPU writes and DMA copies replayed and
compared). Docs: BUILD.md, ENVIRONMENT.md and the libSceAgcDriver debt
file.

%U and %W take the weekday as (tm_wday + 7) % 7 and (tm_wday + 6) % 7
with the C remainder, which fits the PS5 rows of libSceLibcInternal.sprx
and of the libc.prx titles ship. A composite conversion is written part
by part, each part all or nothing. %G, %g and %V throw for a tm_yday
past the year and a tm_wday below -6, where no rule fits the console.

The tests now check the SDK values of the pan error constants, that 0 params leaves the output untouched, that a NaN param angle keeps its LFE level with 7 speakers, and that a param one float below the first speaker in radians throws. The throw messages and the debt entry say the PS5 module did not return within 60 s for those inputs instead of claiming it never returns.

A Windows process started without a standard handle, such as a detached
process or a --windows-gui executable started from Explorer, has
descriptors 0 to 2 whose _get_osfhandle is -2. fcntl then threw on their
unknown file type, which stopped Halo: Combat Evolved (PPSA99500) at
start-up. Open NUL on each of them when libc loads, as Linux and macOS
already open /dev/null on a closed standard descriptor.

rewatchSettledImports passed an import's 64 KiB-rounded span to
Rewatch. For an import whose size is not a block multiple the span's
last block holds pages past the allocation, the walk fails on them, and
the import stayed compared for good. Pass the import's own pages; the
shared-block and live storage image checks still use the block span.
#7948 requires the FMASK of an eight-fragment DCC target to be
write-watched at the initial import and at each reuse. On Windows an
FMASK in a host import whose deferred settle has not run yet is still
compared, so the target is refused with "native FMASK contents require
watched guest memory" after the previous commit has settled its color and
metadata ranges.
Call WatchedAfterSettle for the FMASK range at both checks, as the initial
import already does for the color, DCC and CMASK ranges. A range that is
unwatched without an import awaiting its read is still refused, and
nothing changes off Windows.
Four-sample targets take no FMASK range, so this changes nothing for them.

Rush 2 Recompiled (PPSA69423) and Wave Race 64 Recompiled (PPSA69424)
stop on Windows with "initial multisampled DCC contents require watched
guest memory" (https://github.com/boykopovar/AnyPS5/issues/9724). Their
multisampled color target lives in a 784 KiB host import made at map
time. An import under 1 MiB stays compared until a later lookup reaps
its deferred settle read, and the titles draw to the target first.
When an initial multisampled DCC import needs a range whose import still
waits for its settle read, submit that read now if it is still wanted,
wait for its fence and return the import to the write watch before the
check. This builds on #8527's ordering: the read goes through its
main-queue batch with barriers around it, so it runs after every earlier
main-queue access, and the wait happens under the GPU mutex that
submission holds.
An import that is not a whole number of 64 KiB blocks, such as these
titles' 0xc4000 bytes, never got a deferred read, and Rewatch refuses a
range that does not start and end on a block. Such an import now waits
for this path alone. It returns to the write watch with its partial
blocks whole, each stamped as a CPU store, unless another compared
import or a live storage image shares them.
Imports that stay compared for any other reason still do, an explicitly
unwatched range is still refused, and APS5_NO_DEFERRED_SETTLES still
keeps these imports compared.
The prosper console oracle measured SCE_KERNEL_ERROR_EINVAL for creating
a semaphore with an initial count above the maximum, a maximum of 0, a
negative initial count or a null name, for polling 0 or more than the
maximum, and for signalling 0. These threw, or polled past the maximum
returned EBUSY, and signalling 0 succeeded.

Firmware 13.60 subtracts Expires minus Date and Date minus Last-Modified
on unsigned ticks without comparing them, so either order wraps to a
lifetime that never runs out. Keep that behaviour, state it in the debt
doc, and cover both cases next to their in-order counterparts.

sceNgs2PanGetVolumeMatrix now returns the PS5 error codes in the PS5 check order instead of throwing, and lets NaN angles and distances through as the PS5 module does. sceNgs2PanInit gives the 7-speaker degree defaults for 0 speakers without angles, stores NaN speaker angles and leaves unused slots untouched. Inputs on which the PS5 library never returns still throw.
