Module audio_sidecar_link 

Cold-path audio sidecar linker — bake, hash, mmap-ready bytes, optional native file write.

Links baked tensors to q42:hasSpectralSheet NQuin objects at ingest.

Enums

SidecarBakeKind

Functions

bake_audio_sidecar_into

Bake sidecar bytes into out; returns (content_hash, bytes_written).

compile_spectral_sheet_quin

Emit linker NQuin: subject → q42:hasSpectralSheet → sheet index (lower 60 bits of hash).

enrich_preview_from_sidecar

Hot path: overlay mmap/CQT/STFT column into uniform preview bins.

format_sidecar_relpath

Write relative path spectral/audio/{hash:016x}.bin into caller buffer; returns length.

link_tensor_audio_sidecar

Bake from tensor preview + link quin for cold ingest pipelines.

sidecar_content_hash

FNV-1a over preview bins — stable sidecar filename hash.
