+-- Rollback script for LNM-21-102-DEV legacy advisory backfill migration.
+-- Removes backfilled observations and linksets by querying the backfill_marker field,
+-- then clears the tombstone markers from advisory_raw.
+--
+-- Usage:
+--   psql -d concelier -f ops/devops/tools/ops-scripts/rollback-lnm-backfill.sql
+--
+-- Environment variables:
+--   DRY_RUN - if set to "1", only reports what would be deleted without making changes.
+--
+-- After running this script, delete the migration record:
+--   DELETE FROM schema_migrations WHERE id = '20251127_lnm_legacy_backfill';
+--
+-- Then restart the Concelier service.
