| 2026-08-13T00:00:00+00:00 | fix_hydrate_collapse | MERGED_INTO | Merged into CHEBI:53503 'Cobalt chloride hexahydrate'; occurrences transferred. Tombstoned REJECTED, SSSOM rows dropped (#321/#334). | |

The merge set identifier and status but left ontology_mapping untouched, so this tombstone kept advertising a term it no longer asserts — anything indexing by ontology_id routed through it. Now agrees with the merge target 'Cobalt chloride hexahydrate'. Provenance is unaffected: what the record used to assert is in this history. | |
| 2026-08-29T03:56:37.918511+00:00 | hydrate_duplicate_merges | CORRECTED | cas_rn 7646-79-9 -> 7791-13-1. 7646-79-9 is the ANHYDROUS parent's CAS; 7791-13-1 is the dbxref on CHEBI:53503 cobalt chloride hexahydrate, which this record is grounded to. A hydrate and its anhydrous parent are different substances with different formula weights (#334). | |

The compatibility node id lagged a same-prefix identifier correction; the downstream node id must match the curated identifier unless a record intentionally crosses CURIE prefixes. | |

The token is kept as provenance only; it must not resolve, be exported, or enter the SSSOM other column. |
