MANUAL_CURATION via MIM curation (#213/#308)

The label enumerates its own constituents, so this is a decomposition rather than a mapping: no ontology has a term for 'Yeast + Meat Extract + H2', and none could — a combination is not a substance. Minted under the #288 STOCK_SOLUTION convention and split on '+', which transcribes the label rather than inferring anything. 2 of 3 constituents resolve to existing MIM records via docs/data/label_index.csv; Yeast carries no component_id because MIM has no record for it. ingredient_type=UNDEFINED_MIXTURE because at least one constituent is itself an undefined preparation. No concentrations are recorded: the label states none.

SOURCE_LABEL microbedecoder — Yeast + Meat Extract + H2

The source label explicitly names every retained top-level part.

This is an ingredient/mixture has-part assertion, not an identity mapping, variant hierarchy, or complete culturing recipe.

2026-08-05T00:01:30.894952+00:00 microbedecoder-residual-dispositions LLM FLAGGED_NEEDS_EXPERT NEEDS_EXPERT Not a single-compound grounding target: multi-component blend or named medium; no single ontology term grounds it -- needs decomposition into constituents.
2026-08-06T00:00:00+00:00 edison_literature_identity LLM ANNOTATED Edison LITERATURE (PaperQA3) identity research; report at research/ingredients/Yeast_Meat_Extract_H2-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: ## Curation recommendation — ### Record status CURIEs discussed: CHEBI:18276. Recorded as provenance only — no grounding applied from this run. Edison's recommendations are deliberately conservative, and a plausible identifier promoted by a mechanism that never decided anything is what #203 and #263 exist to undo. Any CURIE above is a curator's to accept or reject.

2026-08-15T00:00:00+00:00 move_mapped_out_of_unmapped_collection MOVED_TO_MAPPED_COLLECTION Moved from unmapped_ingredients.yaml to mapped_ingredients.yaml (#370). The record was already MAPPED; it had been promoted in place by a path that does not move between collections, and reconcile_sssom reads only the mapped collection — so its mapping was curated but unpublished.
2026-08-24T00:00:00+00:00 migrate_component_partonomy TYPED_COMPONENT_PARTONOMY #369: added method/evidence/completeness and explicit reference scope to 3 existing component(s) (MIM_CATALOG, UNMAPPED); constituent names, identifiers, and concentrations were not changed.
