| 2026-08-13T00:00:00+00:00 | merge_minted_hydrate_duplicates | MERGED_FROM | Absorbed 'Trisodium citrate x 2 H2O' (#321), which differs from this record only in notation the merge pass does not recognise as the same substance, so it escaped dedup and was grounded to the anhydrous parent. It had just been minted 'kgmicrobe.compound:trisodium_citrate_x_2_h2o' on the false premise that ChEBI has no term for this hydrate — the record's own CAS 6132-04-3 is registered by ChEBI against CHEBI:32142 'sodium citrate dihydrate'. Occurrences 14/14 + 51/51 -> 65/65. Raw label kept as a RAW_TEXT synonym. | |
| 2026-08-13T00:00:00+00:00 | reground_cas_specific_form | MERGED_FROM | Absorbed 'Sodium Citrate' (#320), whose CAS 6132-04-3 is registered against CHEBI:32142 — the dihydrate of the generic term it sat on. Per the #320 decision the CAS governs, and this record already holds that term. Occurrences 65/65 + 11/11 -> 76/76. | |
| 2026-08-27T03:16:39.519518+00:00 | refresh_occurrence_statistics | CORRECTED | occurrence_statistics 76/76 -> 277/277 (media_count/total_occurrences), derived from distinct CultureMech recipe ids in the #337 occurrence table. The prior values came from the importer retired in #453, whose media_count counted a list truncated to 50 examples (#449).

| 2026-09-02T22:41:49.137449+00:00 | claude_sssom_surface_form_backfill | ADDED_SYNONYMS | Recovered 6 surface form(s) that the published SSSOM `other` carried but no curated record did, so a rebuild would have dropped them from KGX: 'Na2citrate'; 'Na3Citrate'; 'Sodiumcitrate'; 'Trisodium citrate dehydrate'; 'Trisodium citrate·2H2O'; 'Trisodium citrate·3H2O'. Tokens already present on the kg-microbe ontology node were left out as redundant (#520). | |
| 2026-09-12T00:00:00+00:00 | reject_hidden_hydrate_synonym_collapses | REJECTED_HIDDEN_HYDRATE_SYNONYMS | MAPPED | Marked hidden hydrate synonym(s) as REJECTED_LABEL so this record no longer resolves sibling hydrate identities (#251): 'Trisodium citrate·3H2O'. |
