cjm-transcript-correction-core

A frontend-agnostic core for the transcript correction workflow — the first downstream graph-extension core; composes the graph-storage capability worker into a headless pipeline that applies unified, non-destructive corrections (text, punctuation, segmentation) as a supersede-able overlay on a committed decomposition spine, recomputes the review worklist from deterministic signals, and exposes a CLI as its first driver.

Modules

• cjm_transcript_correction_core.cli — The CLI driver — the correction core's first (and currently only) frontend. run corrects the committed spine in the decomp graph DB, pointing the graph worker at that shared DB via load-time config, with optional session resume/reopen; review runs the interactive text-correction loop (the cross-transcriber diff is intra-graph since stage 5).
• cjm_transcript_correction_core.graph — The correction overlay's graph I/O: targeted (scale-shaped) reads of a committed spine via the graph-storage query action, construction of Correction / CorrectionSession nodes + CORRECTS / SUPERSEDES / DERIVED_FROM / REVIEWED edges, the in-core effective-spine projection (layer-0 + applied corrections), and commit through the job queue. Hand-rolled (revolution-1) = direct CR-18 spec material; append-only on layer-0 (never update/delete a Segment).
• cjm_transcript_correction_core.journal — Live append-through for the correction verbs — the workflow journal's domain half.
• cjm_transcript_correction_core.models — Overlay data shapes for the transcript-correction workflow: the Correction / CorrectionSession graph nodes + their relation registry, the read view of a committed spine segment, the worklist item, run configuration, and the correction run manifest (proto-bundle that chains decomp -> correction).
• cjm_transcript_correction_core.pipeline — The headless correction workflow: load a decomp run manifest, resolve the shared graph DB, start/resume/reopen a CorrectionSession, recompute the worklist from deterministic signals + persisted review state, run the D14 empty-segment prune (first operation), and record a chainable correction run manifest — with a cheapest-form HITL approval seam.
• cjm_transcript_correction_core.signals — Pure deterministic Tier-1 signal functions (no capability calls): empty-segment detection, bidirectional boundary punctuation/capitalization heuristics, forced-alignment coverage flags, positional cross-transcriber diff, and phonetic + edit-distance variant clustering. The worklist is recomputed from these each session; revolution-1 builds ZERO new capabilities.
