cjm-transcript-graph-schema

Audio-transcript layer schema for context graphs: Source, AudioSegment, Transcript, and Segment nodes with deterministic identity tuples and graph-node mapping, shared by the transcription, decomposition, and correction workflow cores.

Modules

• cjm_transcript_graph_schema.schema — The audio-transcript layer schema (where-graph-begins locked layer schema): Source -> AudioSegment(coarse boundary) -> AudioRendition(model-input: raw | vocals | ...) -> Transcript(per-transcriber variants) emitted by transcription, extended with the fine Segment spine (per-rendition) by decomposition. Deterministic identity tuples per the stage-5 ratified rule; the AudioRendition node lets raw + preprocessed model-inputs of one boundary coexist in one graph. Document from the pre-CR-18 era dissolves into Source.

API

• AudioRenditionNode class — A model-input rendition OF an AudioSegment — the materialized 16k-mono WAV
• AudioSegmentNode class — Coarse ~5-min spine member: a BOUNDARY range of the Source (an audio fact),
• CollectionNode class — An intrinsic collection (book, podcast series, lecture course) — the
• SegmentNode class — Fine spine member: one VAD chunk — IMMUTABLE audio range + CORRECTABLE
• SourceNode class — The provenance root: one ingested media file.
• TranscriptGraphLabels class — Node labels of the audio-transcript layer schema.
• TranscriptNode class — One transcriber's text for one AudioRendition (per-transcriber variants at
• TranscriptSliceRef class — One per-transcriber char-range reference for a fine Segment: where this
• audio_rendition_node_id function — AudioRendition identity = (audio segment, preprocessing chain).
• audio_segment_node_id function — AudioSegment identity = (source, boundary range).
