| 2026-10-08T08:10:31.707883+00:00 | codex | CURATED_KOMODO_CONCENTRATION_SOURCE_EVIDENCE | Exact medium/source membership, ingredient inventory/forms, physical-state conditions, literal snippets, and arithmetic checked. Stock boundaries, source-only rows, preparation context, and variants remain explicit follow-up tasks; secondary chemical mappings unchanged. KOMODO accession 1117 is mapped to the same DSMZ accession by https://komodo.modelseed.org/servlet/KomodoTomcatServerSideUtilitiesModelSeed?MediaList; mapping response SHA256=d8259d98e6dbffdf6961a1ab92bc86f3567d5d96de352bfa079edb2a91e9580a. The mapping supports identity only, not ingredient quantities or variants. |
