Leave Blu-ray LPCM frames that decode to more PCM than the module's 0x43800-byte output buffer capacity explicitly unsupported, and document the firmware 13.42 wrapping behavior in the technical debt entry. Assisted-by: Antigravity:gemini-3.8-flash

libSceAudiodecCpu technical debt
Unknown function info
- libSceAudiodecCpu codecs - Argument checks and LPCM decode follow firmware 13.60 disassembly, unverified on console. Only 16- and 24-bit Blu-ray stereo LPCM decodes. These throw through
NotImplemented_nid_no_patch: non-LPCM codecs (separate modules), DVD LPCM, non-stereo layouts (channel tables not recovered), frames larger than the 0x43800-byte input buffer, frames whose decoded PCM exceeds 0x43800 bytes (firmware 13.42 wraps output at 276,480 bytes, repeating earlier samples), an AU shorter than its frame or a PCM buffer smaller than the output (the module copies without checking), andInitDecoderwithout AU or PCM. Header byte 7 (frame count) and 33-bit timestamp continuation in the param are inferred. The type mask whensceKernelIsCronosreturns non-zero is not modelled.
