2026-01-27T01:15:03.fZ komodo-web-import Imported from KOMODO web table Source: KOMODO, ID: 966
2026-02-03T11:19:04.210394 dsmz-resolver-v1.0 Enriched with DSMZ composition Copied ingredients from DSMZ Medium 966
2026-03-13T06:19:45.017700Z culturemech-id-assigner-v1.0 Assigned CultureMech ID Assigned stable identifier: CultureMech:006924
2026-03-17T06:30:08.000000Z mediaingredientmech-enrichment-v1.0 Added MediaIngredientMech links Linked ingredients to MediaIngredientMech identifiers
2026-03-17T19:46:03.028034+00:00 normalize_media_names_to_snake_case.py NAME_NORMALIZED Normalized name from "R3 medium" to "r3_medium" for consistent matching
2026-06-05T07:40:28.264611+00:00 mim-legacy-to-chebi-migration-v1.0 Refreshed legacy MediaIngredientMech links to CHEBI keying Replaced 5 legacy mediaingredientmech_term link(s) with mediaingredientmech_chebi_term (id-safe: ingredient's own CHEBI + label). MIM deprecated the MediaIngredientMech:NNNNNN id scheme.
2026-06-08T23:19:28.815045+00:00 chebi-regrounding-v1.0 Corrected CHEBI ingredient grounding (audit G21/G22) Re-grounded 2 term reference(s) to the correct CHEBI (see reports/chebi_grounding_audit.md). Label-conditional fixes for pyridoxine/pyridoxamine, glycerol, MnSO4, Ca(NO3)2, selenate; casamino acids de-grounded (mixture, no single CHEBI).
2026-06-10T07:46:46.554407+00:00 primary-term-label-canonicalization-v1.0 Canonicalized primary term label to OBO canonical (OAK) 2 primary term(s); ingredient name resolved by OAK sqlite:obo:chebi.
2026-10-08T06:29:49.318246+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 966 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.
