| 2026-06-09T05:23:46.807551+00:00 | correct_stale_ontology_labels.py | CORRECTED | ontology_label 'Na2S x 9 H2O' -> 'sodium sulfide nonahydrate': synced to canonical CHEBI label (preferred_term 'Na2S x 9 H2O' unchanged). | |
| 2026-07-20T00:00:00+00:00 | migrate_media_roles_to_facets | ANNOTATED | Migrated legacy media_roles to role facets (#128): REDUCING_AGENT -> physicochemical_roles.REDUCING_AGENT | |
| 2026-08-13T00:00:00+00:00 | fix_scrambled_hydrate_cas | CORRECTED_SCRAMBLED_CAS | cas_rn '1313-82-2' -> '1313-84-4' (#320/#334). The recorded value denotes anhydrous sodium sulfide, contradicting the hydration state this record's own label states. Replaced with ChEBI's hasDbXref on CHEBI:76209, the specific term this record is mapped to — provenance independent of the value being replaced, per MAPPING_SEMANTICS §3. | |
| 2026-08-24T00:00:00+00:00 | regrade_synonym_matches | REGRADED_EXACT_TO_SYNONYM | mapping_quality EXACT_MATCH -> SYNONYM_MATCH (#317). The record's label does not equal the term's primary label 'sodium sulfide nonahydrate'; preferred_term 'Na2S x 9 H2O' matches the ChEBI synonym 'Na2S.9H2O' on CHEBI:76209. The schema defines EXACT_MATCH as a direct match to the term and SYNONYM_MATCH as a match to a known synonym, so the recorded grade overstated. ontology_id is unchanged — the term is correct. The own-identifier SSSOM predicate remains skos:exactMatch under Rule D (#438), independently of mapping quality. | |
| 2026-08-27T03:16:39.519493+00:00 | refresh_occurrence_statistics | CORRECTED | occurrence_statistics 100/1747 -> 2750/2751 (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).

| 2026-08-30T04:48:06.233536+00:00 | claude_culturemech_alias_backfill | ADDED_SYNONYMS | Added 1 CultureMech recipe surface form(s) that folded onto this record's published label but were absent from MIM's label index, so CultureMech could not resolve them: 'Na2S-9H2O' (x1 CultureMech mentions). Source: culturemech:output/ingredient_occurrences.tsv. | |
| 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: '(used for reduction of the medium)'. Tokens already present on the kg-microbe ontology node were left out as redundant (#520). |
