2026-08-05T00:01:30.894952+00:00 microbedecoder-residual-dispositions LLM MERGED_FROM_UNMAPPED_DUPLICATE Absorbed UNMAPPED_0634 '1 % Sodium Lactate' as a RAW_TEXT synonym -- concentration-prefixed duplicate of sodium lactate. No new SSSOM row; CHEBI:75228 is already mapped. Source: kgmicrobe.trait:1_sodium_lactate.
2026-08-13T00:00:00+00:00 fix_comma_split_d_record MERGED_FROM Absorbed the record labelled 'D' (#346). The label 'D' is not an ingredient name: it is the head of a comma-split. This record's own RAW_TEXT synonym, carried over from CultureMech, is '(L-lactic acid, sodium salt)' — so the source label was 'D,L-lactic acid, sodium salt', split at the first comma into 'D' and the remainder. That is DL-lactic acid sodium salt, i.e. stereo-unspecified sodium lactate, which is CHEBI:75228 and is already held by this record. Everything downstream of the split was then derived from the orphaned 'D': cas_rn 138-86-3 (LIMONENE) came from fuzzy-matching 'D' in CultureBotHT compounds_to_cas.csv, and the CHEBI:29958 'L-aspartic acid residue' mapping from matching the one-letter amino-acid code for aspartate. Three fields, three unrelated substances, all artefacts of one split. Occurrences 190/136 + 1/1 -> 191/137. Both the raw split label and the reconstructed source label kept as RAW_TEXT synonyms.
2026-08-27T03:16:39.519849+00:00 refresh_occurrence_statistics CORRECTED occurrence_statistics 137/191 -> 283/283 (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).
