were audible and sounded good.
### Audio-byte migration onto the asset VFS DONE (2026-07-11)
`ResourceMap.BgmPathById` and `ResourceMap.AudioPath` are removed. BGM direct-name resolution now returns a
catalog entry, while voice and SFX retain their scene-local resolution; all three flow through
`ResourceMap.ReadAudio` and the injected `IAssetStore`. `GodotAdvHost` passes owned byte arrays across the
existing deferred main-thread boundary, and `Main` decodes them with
`AudioStreamOggVorbis.LoadFromBuffer` / `AudioStreamWav.LoadFromBuffer`. The existing BGM loop and fade,
voice interruption, ten-channel SFX load/start/release, clock pacing, and gain behavior are unchanged.
Validation: engine **128/128** and both .NET/Godot builds pass. An archive-only SC0000 regression verifies
the Ogg signatures for `BGM005.OGG` and `MAN999.OGG` plus the RIFF/WAVE signature for `E0808.WAV`. With
`extracted/` physically moved aside, the CLI completed SC0000's 127-op audio trace and a windowed Godot run
crossed voice at `0xa0a`/`0xbf6`, BGM005 at `0x7fa`, and the established SFX load/start/preload sequence at
`0xc29`/`0xc2e`/`0xc31` on channels 0/0/4. Godot reported no OGG/WAV read, decode, or deferred-call errors;
`extracted/` was restored afterward. Movie `0x236`, AGF work, opcode semantics, and unrelated VM behavior
were untouched.
