A color target with both DCC and CB_COLOR_INFO.FAST_CLEAR keeps its fast
clear in the DCC keys and fills its CMASK with 0xF (expanded), as radv
does (radv_get_cmask_fast_clear_value) and as PPSA21567 does
(CB_COLOR_INFO 0x10042730, reported on #419). Such targets now decode;
their clear is materialized by the existing DCC path. A DCC target's
CMASK that is not all expanded throws.

Draws into a color target with CB_COLOR_INFO FAST_CLEAR (bit 13) were
rejected. The CMASK keeps one nibble per 8x8 tile: 0 means the tile is
fast-cleared and reads as CB_COLOR_CLEAR_WORD, 0xF means expanded (the
texels hold the color). The texture units and display scanout do not read
it, so a title runs a fast-clear eliminate pass before sampling or
flipping such a target.
DecodeColorBuffer now takes the CMASK address (CB_COLOR0_CMASK and
CB_COLOR0_CMASK_BASE_EXT) and the bytes one nibble per 8x8 tile spans.
Before a draw renders into the target, and in a fast-clear eliminate
pass, a CMASK whose nibbles are all 0 is materialized: the target is
filled with the clear texel (FillClear on its resident image, else
guest memory on the CPU) and the CMASK bytes are stored as expanded,
through the same GPU-ordered store as the DCC "uncompressed" keys
(0xFF either way). The result equals the draw followed by the eliminate
pass. An all-expanded CMASK changes nothing; a mixed one throws, as do
fast clears of DCC, mipmapped, 3D and array targets.
PPSA14632 (LEGO Horizon Adventures) fast-clears its two 3840x2160
display buffers through CMASK, so its final composite draw was dropped
on every frame and only black was presented.

A 16-bit PCM block whose num_samples exceed its data starts a stream, and waveform blocks with flag 0x2 append more data to it. The voice outputs silence while it has played all appended data and CONTINUE is set, and ends at num_samples or when CONTINUE is cleared.
Measured on a PS5 (firmware 13.60) through dlopen of
libSceVoiceQoS.sprx: a null block, any size other than exactly 0x40000,
and an app type other than 0x20000000 or 0x10000000 all return
0x804E0902 without touching the block, instead of throwing. A second
initialization returns 0x804E0905, as prosper reads from the module.

Add scePadOpenExt for special ports, which return DEVICE_NOT_CONNECTED because the host has no special controller, and the extended read and report exports, which throw.
Once an image has .ehmeta, an eh_frame_hdr version other than 1, an
eh_frame_ptr encoding other than absptr or pcrel, a 64-bit record length,
an eh_frame_ptr outside the image or a missing terminator now throw
instead of returning the empty answer. The test queries a fixture DLL
whose .ehmeta it can break, since the unwinder reads the same section.

A year before 1980 or after 2107 cannot be packed into the DOS time, so
GetDosTime threw. Following the disassembly-derived fpPS4
reimplementation of the PS4 library, it now returns INVALID_YEAR after
writing 0 for an earlier year and 0xff9fbf7d, the largest encodable
time, for a later one. The TechnicalDebt entry now records fpPS4 as the
source for the SetDosTime year decode as well.
A captured grain stored only the port slot and data pointer, so a port
created in a destroyed port's slot before the next push mixed the old
pointer with its own format. Ports now carry a generation that the
capture records. TechnicalDebt notes that the last grain pushed before a
title stops is never played.

The Smurfs Dreams imports both and no library exports them, so eager
binding stops the title before it starts. sceAudioInAsyncOpen throws
like the other AudioIn opens that have no implementation;
sceHttp2SetMinSslVersion returns success like the other Http2 SSL
setters, as no request reaches the network.

The host mixes without the console's mastering stage, so the mastering
parameters have nothing to configure, as with sceAudioOut2MasteringInit.
Accept them instead of aborting, keep throwing for a null parameter
block, and record SetParam next to MasteringInit in TechnicalDebt.

Return the id a graphics event was registered with in
sceAgcDriverAddEqEvent, which titles derive from their context
(PPSA12544: 0 or 1 for graphics, 0x20 + 8 * pipe + queue for compute) and
read back to dispatch the event. Other event filters, a null or
misaligned event and an id above 32 bits throw. The meaning is an
assumption and recorded in the technical debt.

GuestAppContent now writes a param.json that declares downloadDataSize 0
and checks that sceAppContentDownloadDataGetAvailableSpaceKb returns OK
with 0 KB for /download0 (it threw before), and PARAMETER for a null
result. TechnicalDebt records that the console's behaviour for such a
title is unverified.
