| 2026-04-19T07:39:23.955331+00:00 | audit_mim_merge | MERGED_FROM_DUPLICATES | MAPPED | Absorbed 1 duplicate MIM record(s) into this one: Potassium_sulfate.yaml. Synonyms, curation_history, and occurrence counts were unioned/summed; winner selected by highest occurrence count with preferred_term readability tie-break. |

| 2026-06-09T05:23:46.780296+00:00 | correct_stale_ontology_labels.py | CORRECTED | ontology_label 'K2SO4' -> 'potassium sulfate': synced to canonical CHEBI label (preferred_term 'K2SO4' unchanged). | |
| 2026-07-20T00:00:00+00:00 | migrate_media_roles_to_facets | ANNOTATED | Migrated legacy media_roles to role facets (#128): MINERAL -> nutritional_roles.SULFUR_SOURCE | |
| 2026-07-20T20:01:42.981644+00:00 | migrate_media_roles_to_facets | CORRECTED | Added nutritional role(s) MINERAL_SOURCE missed by the initial #128 migration: the residual MINERAL_SOURCE bucket was suppressed whenever any other target existed, which dropped the bulk cation from salts whose other role describes the anion (e.g. MgSO4). | |
| 2026-08-27T03:16:39.519055+00:00 | refresh_occurrence_statistics | CORRECTED | occurrence_statistics 51/76 -> 138/138 (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).

| 2026-09-02T17:40:44.716277+00:00 | claude_sssom_surface_form_backfill | ADDED_SYNONYMS | Recovered 1 surface form(s) that the published SSSOM `other` carried but no curated record did, so a rebuild would have dropped them from KGX: 'K2SO4·7H2O'. Tokens already present on the kg-microbe ontology node were left out as redundant (#520). | |
| 2026-09-12T00:00:00+00:00 | fix_malformed_hydrate_identities | REJECTED_MALFORMED_HYDRATE_ALIASES | MAPPED | Marked malformed hydrate alias(es) as REJECTED_LABEL so they remain on their own #344 local identities only: 'K2SO4·7H2O'. |
| 2026-09-12T00:00:00+00:00 | fix_malformed_hydrate_identities | REFRESHED_MALFORMED_SULFATE_OCCURRENCES | MAPPED | occurrence_statistics 138/138 -> 134/134 after moving CaSO4/K2SO4 x 7 H2O memberships off the anhydrous parent identifiers (#344). |
