2026-01-28T19:48:38.157199Z chebi-enrichment Added CHEBI ontology terms to ingredients Enriched using MicrobeMediaParam and MediaDive chemical mappings
2026-03-13T06:19:06.388354Z culturemech-id-assigner-v1.0 Assigned CultureMech ID Assigned stable identifier: CultureMech:001676
2026-03-17T06:30:46.000000Z mediaingredientmech-enrichment-v1.0 Added MediaIngredientMech links Linked ingredients to MediaIngredientMech identifiers

2026-06-05T07:41:40.274764+00:00 mim-legacy-to-chebi-migration-v1.0 Refreshed legacy MediaIngredientMech links to CHEBI keying Replaced 4 legacy mediaingredientmech_term link(s) with mediaingredientmech_chebi_term (id-safe: ingredient's own CHEBI + label). MIM deprecated the MediaIngredientMech:NNNNNN id scheme.
2026-06-08T23:19:49.461814+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).
2026-10-07T12:21:30.028294+00:00 codex CURATED_MEDIUM_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.
