# linksets-m0 dataset plan (CONCELIER-CORE-AOC-19-004)

Purpose: produce deterministic dataset for STORE-AOC-19-005 rehearsal.

Generated artefacts:
- `out/concelier/backfill/linksets-m0.ndjson.gz` — placeholder deterministic NDJSON (stub until real export).
- `out/concelier/backfill/linksets-m0.ndjson.gz.sha256` — SHA256 `21df438c534eca99225a31b6dd488f9ea91cda25745f5ab330f9499dbea7d64e`.

Generation instructions (replace stub when real export is ready):
1) Export from staging Mongo using `scripts/concelier/export_linksets.sh --tenant default --output out/concelier/backfill/linksets-m0.ndjson.gz --gzip`.
2) Verify determinism: `python3 scripts/hash_ndjson.py out/concelier/backfill/linksets-m0.ndjson.gz` and compare across two runs (hashes must match).
3) Update `.sha256` file with the new hash.

Status: stub dataset and hash published 2025-11-19 to unblock rehearsal scheduling; replace with real export when available.
