Sources ledger

Skill jperrello/C0BALT_CUT/.claude/skills/sources-ledger

Maintain work/sources.json — the registry of which source videos have been processed into shorts. Scans every work/<id>/ingest.json + the output/<slug>/ folder it produced, recording title, url, duration, the produced shorts (with grades/tiers), current disk footprint, and active|reaped status. Also mirrors a keyed per-source bd memory so future sessions recall what's already been clipped (and can re-ingest from the saved URL). Pure deterministic scan, idempotent, no Claude. The "memory" half of the disk-hygiene pair (reap-source is the "cleanup" half).From its SKILL.md

sources-ledger

The registry of what's been clipped. Answers "have I already made shorts from this video?" and "where did a reaped source come from?" without decoding opaque work/<sha1> hashes.

Usage

sources-ledger.sh sync          # rebuild work/sources.json from work/ + output/
sources-ledger.sh record <id>   # upsert one source (pipeline end-of-run / reap)
sources-ledger.sh show          # print the registry

Output: `work/sources.json`

An array, newest-ingested first, one entry per source that has an ingest.json:

{
  "id": "ac3763ad4c",
  "slug": "we-broke-into-mrbeast-s-studio",
  "title": "We Broke Into MrBeast's Studio",
  "url": "https://www.youtube.com/watch?v=y8K6QazBqrY",
  "uploader": null,
  "duration_sec": 5726.174,
  "ingested": "2026-06-01",
  "shorts": [ { "name": "....mp4", "grade": 72, "tier": "GOLD", "path": "output/<slug>/....mp4" } ],
  "shorts_count": 3,
  "status": "active",
  "reaped": null,
  "work_bytes": 2782512345
}

slug is computed identically to start.sh (kebab of the source title, falling back to the work id) so it maps work/<id> → output/<slug>/.
status is reaped once source.mp4 is gone or a .reaped marker exists (written by reap-source); otherwise active.
shorts reads each delivered output/<slug>/*.mp4 and its co-located *.grade.json.

bd memory

record also upserts a keyed memory (--key source-<id>) summarizing the source + how to re-ingest, best-effort (skipped if bd is absent). Keyed, so re-runs update in place rather than duplicating.

Where it runs

Pipeline end-of-run — start.sh calls sources-ledger.sh record <id> after a source's shorts are saved, so the registry is always current.
reap-source calls record <id> after reaping to flip status → reaped, then a final sync.
Standalone — sync backfills the whole registry from existing work/ dirs.
