Bugsnax (PPSA01503) draws with DB_ALPHA_TO_MASK 0xe701 (quad offsets
3, 1, 2, 3 without OFFSET_ROUND) on a two-sample target and stopped on
the refusal of every dither but the eight-sample 0x18701. The pixel
shader now applies an eight-level per-quad table for it, measured
natively on gfx1032, and the request's dither byte selects that table
(serialization version 47). It is accepted only for two matched raster
and DB_EQAA samples, the two measured location pairs and FP16_ABGR or
32_ABGR exports.

The printf family formatted floating-point conversions through the host,
which prints every exact digit and rounds ties to even. The libc.prx
that titles ship keeps the exact digits only down to a position derived
from the binary exponent and prints zeros after them, rounds half up on
the kept digits, and rounds an exact tie down once that exponent
estimate reaches 8. So %.0f of 2.5 is 3 and %.1f of 0.25 is 0.3 there,
and %.20f of 0.1 is 0.10000000000000000555.
Format finite double and long double e, f and g conversions with those
rules from exactly generated digits, on every host. On 600,000 random
formats every output with up to 17 significant digits now matches the
copies bundled with PPSA07923, PPSA05916 and PPSA13934; longer outputs
still differ where the console's extended-precision digits end one unit
lower.

The libc debt entry for %a and %A still described the Windows-only
formatter and said Linux hands %a to glibc; since Linux routes %a and %A
to the same formatter, describe it for both platforms.

The Windows printf family handed %a and %A to the host, whose UCRT prints
a subnormal unnormalised (0x0.0000000000001p-1022) and pads with zeros
even when the - flag is given (%-010a of 1.5 gave 0x001.8p+0). The
libc.prx that titles ship normalises subnormals (0x1p-1074), rounds a
shorter precision half up without renormalising a carry, and lets -
override 0, as C requires.
Finite doubles are now formatted here, checked against three titles'
copies of libc.prx run side by side.

pthread_mutexattr_setkind_np stored only kinds 1 to 4 and threw for others.
FreeBSD 11.4 stores any kind, pthread_mutexattr_gettype rejects kinds of
PTHREAD_MUTEX_TYPE_MAX or more with EINVAL, and mutex_check_attr makes
pthread_mutex_init fail with EINVAL for a kind outside the mutex types.

The Windows registration check fails when a test executable is built but no ctest test runs it. Put the executable under ANYPS5_RUN_QUARANTINED_FRAME_REPLAY as well, so OFF neither builds nor registers it and ON does both.
The recorder reads a delta block with ReadCommittedUnsynced while the second DMA copy into it is still in flight, so the capture can hold zeros and the replay then does not reproduce the second copy. The test failed intermittently on the Windows lane. Do not register it on Windows unless ANYPS5_RUN_QUARANTINED_FRAME_REPLAY is ON, and list it in the libSceAgcDriver technical debt.
Main limits the standard port to logged-in users, so scePadOpen now checks the port type alone first, then the user and index, and leaves the standard port's user lookup to PortForUser.

v_cvt_f32_ubyte0 to v_cvt_f32_ubyte3 take byte N of source 0 after
SRC0_SEL and SRC0_SEXT select and extend it, as measured with the
hardware oracle on RDNA2 (gfx1036) for all seven source selects with
and without SRC0_SEXT. The test checked four combinations derived from
the ISA guide; it now checks every combination against the measured
results, and the debt entry keeps only what is not measured: gfx1013.

TakeStorage copies a pending or live storage image over the whole depth
plane of a new single-sample surface, after the creation clear. On AMD's
Windows driver 32.0.31041.1004 (RX 7800 XT), one or two 8x8 blocks of a
D16 surface then tested as the clear value in about 1 of 10 runs of
agc_driver_depth_surface_from_storage, although a copy back of the image
read the copied values (#6630).
Without a stencil plane the copy now goes through an UNDEFINED to
TRANSFER_DST_OPTIMAL barrier on the depth aspect and back to GENERAL, so
the clear's state is discarded before the copy writes every texel. A
surface with a stencil plane keeps the previous path.
