A null batch address is refused whatever the size, so the accepted batch
of zero bytes is one at a real address, which is what TestConsoleEmptyBatch
starts.

A probe on a PS4 decoded exactly one frame and reported 0 for an ATRAC9
run job without RUN_MULTIPLE_FRAMES. Jobs read from a PS4 batch buffer
now do the same. Jobs from the PS5 builders keep decoding their whole
input, which FMOD in PPSA29141 relies on.

sceAjmBatchStartBuffer let a null batch of zero bytes through its
parameter check and formed the end pointer from it. A null batch now
returns INVALID_PARAMETER whatever the size, as the PS5 builders'
sceAjmBatchInitialize does; a batch of zero bytes still starts, runs
nothing and completes at once. A test covers both; neither was measured
on a console, which the debt entry says.

The gapless entry no longer says the one-frame behaviour is unverified,
since the probe measured it, and the libSceAjmi entry names the two
exports its file declares.

Review of the PS4 batch buffer change. The libSceAjmi stub of
sceAjmBatchJobRunBufferRa stays, declared with the _nid_disambig1 suffix
so that both libraries export the NID without defining one name.
sceAjmBatchStartBuffer reads the whole batch before running any job, as
probe batches on a PS4 showed: a buffer chunk of size zero is dropped
whatever its address, and a null address with a nonzero size refuses
the batch with INVALID_ADDRESS in the error record together with the job
chunk, the chunk's offset in the job and the job's return address, with
nothing of the batch run. Inputs and outputs share that rule. The
console-measured result flags move from test comments to the debt
entries.

PS4 titles build AJM batches with the SDK's inline helpers, which call
sceAjmBatchJobControlBufferRa, sceAjmBatchJobRunBufferRa and
sceAjmBatchJobRunSplitBufferRa and start the buffer with
sceAjmBatchStartBuffer. The buffer belongs to the title, so it has to use
the console's chunk layout rather than this library's private records.
The builders write console jobs (job, return address, buffer and flags
chunks) and return the position after them. StartBuffer checks the
context, walks the chunks, skips inline data and runs each job as the
library's existing control, run or statistics job. Chunk headers are read
as the console's builders write them: bits 0-3 the kind, bit 4 a buffer's
output direction, bits 6-25 the payload; the other bits keep a reused
buffer's old bytes on a PS4. Malformed batches return MALFORMED_BATCH,
unknown chunk kinds and unimplemented control flags throw.
An ATRAC9 run with RUN_MULTIPLE_FRAMES reports which side ran out as a
PS4 does (0x8 input, 0x10 room, 0x18 both), and the ATRAC9 format reports
the frame's bitrate; both were measured on a PS4 with Knowledge is Power:
Decades (Wwise) batch dumps and probe runs. The vibration test's exact-fit
run expects 0x18 accordingly.
The throwing stubs in libSceAjm and the libSceAjmi copy of
sceAjmBatchJobRunBufferRa are dropped.

sceAjmDecWVorbisCreateHeaderPacket checks its 0x48-byte parameter as the
PS5 module does and writes a five-entry length table, a Vorbis
identification header from the parameters, an empty comment header and
the setup packet.

Parse Xing/Info and LAME tags across candidate offsets covering both CRC-protected and unprotected streams, and accept VBRI headers at byte 36 for non-stereo / MPEG-2 frames. Reject non-Layer-3 streams with SCE_AJM_ERROR_INVALID_PARAMETER without throwing.
Progress: sceAjmDecMp3ParseFrame implemented (libSceAjm.native: 19/40 -> 20/40, 50.0%)
AnyPS5 resolves a title's imports by NID, so a title that imports a system
function no library provides fails to load with an unresolved import. The
PS5 3.20 export inventory lists 193 such exports across 37 PS5 system
libraries AnyPS5 implements but does not provide.
Declare them as throwing stubs so those titles load and reach their next
blocker. Each declaration calls NotImplemented_nid_no_patch and returns 0;
none of them implements the function. Declarations with a credible
prototype use it and cite the source with a pinned commit, and the rest
are declared without parameters, which resolves the import without making
an ABI claim. The technical-debt files record the limitation per library.
libSceMbus and libSceSystemService are left out because pull request #7821
declares them. libSceAgc is left out because its exports are versioned, so
the 3.20 NID names a different symbol from the one AnyPS5 ships.
libSceAvPlayer.native is left out because it compiles libSceAvPlayer's
Export.cpp.
Names and NIDs come from the PS5 3.20 export inventory at

Broken Sword - Shadow of the Templars: Reforged (PPSA21480) decodes its
audio itself and uses AJM codec 23 only to resample interleaved s16 PCM
from 44.1 to 48 kHz: every block initializes the instance with
0, 2, 44100, sets the ratio 0.91875 and decodes 235 frames into a
256-frame output. The run threw "AJM: decoding codec 23 is not
implemented".
A codec 23 run now consumes its whole input and emits every output
frame whose position lies inside it, with the Catmull-Rom of the
existing resampler. Cases the title does not show throw, among them a
run after a resampled run without a new initialize.
Broken Sword - Shadow of the Templars: Reforged stops at AJM decoding codec 23, which is not one of the codec ids known in Ajm.cpp (MP3 0, ATRAC9 1, M4AAC 2, Opus 24).

Ghost of Yotei (PPSA26344, v1.008, eboot 0x2e1cfc) creates an M4AAC
instance (codec 2) and calls sceAjmBatchJobControl with flags
0x200000006000 (RESET | INITIALIZE | SIDEBAND_GAPLESS_DECODE), 8 bytes of
gapless decode plus 8 bytes of M4AAC initialize parameters and an 8-byte
result (#884); INITIALIZE for M4AAC threw on main.
- INITIALIZE (control and sceAjmBatchJobInitialize) reads the 8-byte
{config type (1 ADTS, 2 raw), sampling frequency index} block of
shadPS4 ajm_aac.h at 443f0224; an invalid type or a raw index above 11
returns the invalid parameter result. Raw input is configured from the
instance channels (0 is stereo) as in shadPS4 ajm_aac.cpp.
- RUN decodes ADTS frames (length from the header) and raw access units
(the whole input, as fdk-aac's raw transport) with FFmpeg's AAC decoder
into the instance's S16, S32 or float PCM, with the framework's gapless,
resampling, stream, format and multiple-frames sidebands.
- Without ENABLE_NONDELAY_OUTPUT the first two frames after
initialization or reset produce no output, as in shadPS4. A decoder
error returns CODEC_ERROR | FATAL. The codec info is {heaac, reserved};
the format reports the last frame's bitrate with fdk-aac's formula.
- Throws for what the sources do not settle: ADTS resynchronization,
profiles other than AAC LC, several raw data blocks per frame, channel
configurations other than 1, 2 and 6, more channels than the instance,
HE-AAC without ENABLE_SBR_DECODE, raw input with RUN_MULTIPLE_FRAMES or
several access units, a frame longer than the reserved room, and
unknown codec flags.
guest_ajm decodes an embedded 5-frame stereo ADTS fixture (two chirps,
encoded by FFmpeg 6.1.1's aac encoder at 64 kbit/s) frame by frame, in
one multiple-frames run, as float, as raw access units and with gapless
trimming, and checks sample counts, format, codec info, the delay frames,
RESET, partial input, missing room and the correlation of each channel
with its input chirp at the 1024-sample encoder delay; plus the
INITIALIZE validation results and the refusals.

A family 255 instance with more than one channel carries no stream count
or mapping in its initialization words, so its decoder now opens on the
first packet: the multistream packet's self-delimited streams are counted
(RFC 6716 appendix B), each stream's TOC stereo flag marks it as coupled,
and the channels map in order. A packet whose streams do not make the
channel count throws.
Metal Gear Solid 4 Master Collection (PPSA18194) initializes a 4-channel
family 255 decoder for its intro movie.
