libSceAudioPropagation technical debt

libSceAudioPropagation lacks acoustic propagation: attributes have no effect, sources expose no paths or rays, rendering preserves the destination mix without adding path contributions, and memory queries return only a 16-byte CPU header. Ray results and audio paths accept empty lists and throw otherwise; calculation returns initial native validation errors and throws for unsupported propagation. Room, portal, source and material handles are tracked, but destruction after their system is destroyed silently succeeds without native lifetime semantics being confirmed. Occlusion, reflections and reverb are absent.

sceAudioPropagationSourceSetAudioPath: the native path lookup and update confirm a 64-bit path handle, a read-only 224-byte path description and a float gain in XMM0. The description contains four 48-byte points, a point count and flags; each point contains a descriptor, room handle, gain and three position floats. The last eight bytes of each point and of the description are not consumed by these paths and remain opaque. Protected implementation remains unchanged; allocation, ownership and rendering are not implemented.
libSceAudioPropagation: system options and frame configuration remain unknown. Descriptor validation, ray ownership and path generation are unimplemented. Native rendering accepts multiple mutable records; the host supports only format 2 and writes silence over the supplied capacity, without native accumulation or frame/count limits. Other formats and native validation precedence remain unimplemented. Source/system diagnostic fields still need reconstruction.
Initialization exports ending in Init, plus sceAudioPropagationSystem, are absent from the supplied native module and retain unresolved signatures. Query, locking, enumeration and report callback signatures are recovered; source/system diagnostic fields still need reconstruction.
