2026-05-11T04:08:29Z mediaingredientmech-agentic-curation LLM MERGED_FROM_UNMAPPED_DUPLICATE MAPPED Absorbed duplicate unmapped record A-Ketoglutaric_Acid.yaml (UNMAPPED_0266); local mapped CHEBI:30915 record represents alpha-ketoglutaric acid and the unmapped surface form is the alpha/a notation variant used in CultureBotHT.
2026-06-16T00:00:00+00:00 merge_duplicate_unmapped LLM MERGED_FROM_UNMAPPED_DUPLICATE MAPPED Absorbed duplicate UNMAPPED_0323 "alpha-ketoglutamate". Edison deep research (9 citations) resolved it as a misspelling of alpha-ketoglutarate = 2-oxoglutarate — the SAME compound as this CHEBI:30915 record, not a distinct ingredient. Promotion was refused by promote_resolved_unmapped.py (PK collision on CHEBI:30915), so merged the surface form here as a synonym instead.

The prior values came from the importer retired in #453, whose media_count counted a list truncated to 50 examples (#449).
