Refs #1 - observations: hcl backfilled from local rowid; (node_id, hcl) UNIQUE locator index becomes the gossip merge key - threads: cluster_key column + partial UNIQUE index; CreateThreadCluster is idempotent, threader folds into exact cluster_key before heuristic - AutoLinkThreadObservations dedup re-expressed on hcl DESC - new `knox reconcile [--dry-run]` rebuilds entries from the observation log and re-links threads idempotently (entry count, thread cluster_key verified bit-identical from log-only DB)
