CURATOR_JUDGMENT
via MIM curation (#368)
A culture-media ingredient named sulfur, sulphur, or sulfur powder denotes weighable elemental sulfur, not ChEBI's sulfur atom or polysulfur terms.

| 2026-05-29T23:35:36.113121+00:00 | extract_roles_from_synonyms | ANNOTATED | Added media role: MINERAL (confidence: 1.00) | |
| 2026-06-09T05:23:46.840780+00:00 | correct_stale_ontology_labels.py | CORRECTED | ontology_label 'Sulphur' -> 'polysulfur': synced to canonical CHEBI label (preferred_term 'Sulphur' 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 | |
| 2026-08-13T00:00:00+00:00 | fix_wrong_compound_cas | CORRECTED_WRONG_COMPOUND_CAS | cas_rn '12597-03-4' -> '7704-34-9' (#320). The recorded value denotes trisulfur specifically, not polysulfur — a different compound, not a different form of this one. Replaced with ChEBI's hasDbXref on CHEBI:17909, the term this record is already mapped to, so the new value comes from the existing mapping rather than a fresh lookup. | |
| 2026-08-27T03:16:39.519931+00:00 | refresh_occurrence_statistics | CORRECTED | occurrence_statistics 5/5 -> 7/7 (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] | |
| 2026-09-11T13:41:33.694587+00:00 | fix_sulfur_family | MERGED_INTO | REJECTED | Merged into CHEBI:33403 'Sulfur'; occurrences transferred to the surviving elemental sulfur record and SSSOM rows dropped. The old record CHEBI:17909 split a spelling or supplied powder form from the same weighable sulfur substance (#368). |
