2026-07-20T00:00:00+00:00 migrate_media_roles_to_facets ANNOTATED Migrated legacy media_roles to role facets (#128): MINERAL -> nutritional_roles.MINERAL_SOURCE
2026-08-27T03:16:39.518471+00:00 refresh_occurrence_statistics CORRECTED occurrence_statistics 59/146 -> 199/199 (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: 'Ca(NO3)2•4H2O' (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: '(1) Ca(NO3)2'. Tokens already present on the kg-microbe ontology node were left out as redundant (#520).
2026-10-03T07:30:00+00:00 yaml_record_review MERGED_SOURCE_OCCURRENCE Moved the CAS-qualified Ca(NO3)2•4H2O source label and three CultureMech occurrences from stale UNMAPPED_0049 onto this calcium nitrate tetrahydrate identity; the truncated Ca placeholder was retired instead of mapping to elemental calcium.
