RackGetInfo reports the rack's handles, buffer, id, uid, option limits,
render count and active voices. VoiceGetPortInfo reports a port's matrix,
volume and destination. VoiceQueryInfo answers info id 0x4001 with the
voice channel count and throws for other ids. Assumptions are recorded in
TechnicalDebt.

sceLoginDialogGetResult zeroed 8 bytes of a result struct of unknown size and reported result 0
with user id 0. It now writes only the leading int32 (USER_CANCELED), like
sceWebBrowserDialogGetResult and like the sign-in dialog, so a title takes its "no user chosen"
path instead of reading an invalid user id. Records the dialog in the silent-stubs list in
docs/dev/TechnicalDebt.md.
Per review: sceUserServiceGetNpAccountId reports success with account id 0 and
sceUserServiceGetUserColor returns blue by default; both are assumptions. Records them under
"Unknown function info" in docs/dev/TechnicalDebt.md.
* feat(libkernel): implement sceKernelReleaseFlexibleMemory
Unmaps the range through sceKernelMunmap, which returns its pages to
the flexible memory budget, as fpPS4 and prosper do.

* test(libkernel): keep the flexible memory release check apart from the batch map checks

sceAgcCbCondWrite writes the 9-dword COND_WRITE packet: poll a memory
dword, compare it masked with the reference, and write a dword to memory
on a match. sceAgcCbCondWriteGetSize returns its 36 bytes.

sceAgcAsyncCondExecPatchSetCommandAddress and
sceAgcAsyncCondExecPatchSetEnd patch the COND_EXEC packet like their
graphics counterparts, since sceAgcAcbCondExec writes the same packet
as sceAgcDcbCondExec. Both variants share one implementation, as the
REWIND patches do.

The query writes the maximum resource name length (0xfc) through its
output pointer and returns 0, as prosper does from a title's registration
configuration. The parameter follows the SDK wrapper
sce::Agc::ResourceRegistration::getMaxNameLength(unsigned int*). Resource
registration itself stays unavailable.

Rack 0x2001 is created with its option layout and KytyPS5's defaults, takes
the setup (0x20010000) and I3DL2 (0x20010001) voice params and reports the
common voice state. The voice mixes its inputs and runs a Freeverb-style
approximation driven by the I3DL2 parameters: room and room HF, early
reflections and their delay, late reverb and its pre-delay, decay time and
HF ratio, and diffusion. Out-of-range params throw, param changes keep the
tail, a stop or kill clears it, and the tail ends once it decays below
1e-20. The console's algorithm is unknown; the approximation is recorded in
TechnicalDebt. The test context buffer pool grows to 64.

Mastering voice param 0x30000004 sets a full-band and an LFE level. They
scale the mastering voice when it is mixed into the render buffer, the LFE
level on channel 3 of 6- and 8-channel voices. Non-finite levels are
invalid arguments.

The SDK 9 libc.prx heap maps its arenas with flag 0x8000, which threw as
an unsupported flag. The flag is ignored for this function, as sharpemu
does; other unknown flags still throw.

Whether the console's parser rejects 1e309 or stores an infinite real
is unknown, and RFC 8259 allows both. Following the exact-or-throw rule,
sce::Json::Parser::parse now throws with the number text and a note that
the behaviour is unverified, instead of returning JsonErrorParse. The
partially built tree is freed before the exception leaves the parser.
The case is listed under unknown function info in TechnicalDebt.md.

sceAgcWriteDataPatchSetDst, sceAgcWriteDataPatchSetCachePolicy, their
Async forms and sceAgcAsyncWriteDataPatchSetAddressOrOffset threw. They
now rewrite a WRITE_DATA packet in place: the destination in the
graphics (sceAgcDcbWriteData) or compute (sceAgcAcbWriteData) encoding,
the cache policy in bits 25-26 and the address in dwords 2-3, so the
patched packet equals the one written with those values. A register
destination is rejected when the packet requests write confirmation,
as when the packet is written.

PPSA14632 (Unreal Engine) writes sceAgcCbBranch(mode 1, compare
function 0, mask 0, reference 0) with a then buffer and a null else
buffer of 0 dwords. It leaves the compare address uninitialised, so it
is sometimes only 4-byte aligned. The writer rejected the null else
buffer and the misaligned compare address, and the driver accepted
opcode 0x3f only as the 4-dword INDIRECT_BUFFER, so the 14-dword branch
would have failed at submission.
sceAgcCbBranch no longer checks the compare address of an always-pass
branch, which reads nothing, or the address of a buffer of 0 dwords.
The driver runs the first buffer of an always-pass COND_INDIRECT_BUFFER
in modes 1 and 2 (if-then and if-then-else) in place of the packet. A
comparison, a predicated branch and other modes throw.

The 106-key (Japanese) arrangement threw. Its alphanumeric layer now
follows the JIS layout of the HID usages: the symbol keys right of the
digits and letters, the Ro key (0x87) and the Yen key (0x89). With the
Kana LED set it still throws, as the kana the console returns are
unknown.
