chore(scripts): add segmented-transcript backfill script#122
Merged
Conversation
Re-runs the spec #18 segmented cleanup (TranscriptCleaningProcessor) on episodes that have a cleaned Markdown transcript but no AnnotatedTranscript JSON sidecar, so every episode gets a segmented view. This backfilled the 5 stragglers that predated the segmented pipeline (coverage now 866/866), which was the prerequisite for dropping the legacy-blended tab in #120. Idempotent: skips episodes that already have a sidecar unless --force. Dry-run by default; --apply to write; --episode-id to target specific rows.

Follow-up to #120 (which dropped the legacy-blended/shadow transcript tabs). That PR merged the frontend change but not the script that made it possible — this PR adds it.
What
scripts/backfill_segmented_transcripts.py— a one-off, idempotent repair that re-runs the spec #18 segmented cleanup (TranscriptCleaningProcessor) on episodes that have a cleaned Markdown transcript but noAnnotatedTranscriptJSON sidecar. This is what backfilled the 5 stragglers that predated the segmented pipeline, bringing coverage to 866/866 so the legacy tab could be removed.--applyto write;--episode-idto target specific rows;--forceto re-clean episodes that already have a sidecar.--force, so re-running is safe and won't re-spend LLM tokens.Note
Uses
print()for CLI output, consistent with the siblingscripts/backfill_feed_holes.py.scripts/is one-off operational tooling, not application code.
