2026-06-02T07:05:13.391914+00:00 infer_roles_from_name_lists ANNOTATED Added media role: MINERAL (confidence: 0.80)
2026-06-09T05:23:46.808404+00:00 correct_stale_ontology_labels.py CORRECTED ontology_label 'Na2SO4 x 10 H2O' -> 'sodium sulfate decahydrate': synced to canonical CHEBI label (preferred_term 'Na2SO4 x 10 H2O' 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).
2026-08-27T03:16:39.519511+00:00 refresh_occurrence_statistics CORRECTED occurrence_statistics 4/4 -> 6/6 (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). [source=ingredient_occurrences.tsv culturemech_rev=15a4da5c08 rows=194137 distinct_recipes=15257]
2026-09-02T22:41:49.137449+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: 'sodium sulfate, anhydrous'. Tokens already present on the kg-microbe ontology node were left out as redundant (#520).
