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 '2-butanol+CO2', 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. 1 of 2 constituents resolve to existing MIM records via docs/data/label_index.csv; 2-butanol carries no component_id because MIM has no record for it. ingredient_type=DEFINED_MEDIUM because every constituent is a defined chemical (an unresolved name here means MIM lacks the record, not that the substance is undefined). No concentrations are recorded: the label states none.

Decomposition evidence

SOURCE_LABEL microbedecoder — 2-butanol+CO2

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

CURATED_DATASET mappings/microbedecoder_residual_research_decomposition.tsv — 2-butanol+CO2

Reviewed row: strategy=split, confidence=high; Secondary-alcohol donor + CO2 acceptor.

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

2026-08-04T02:54:09.684805+00:00	audit_import_ingredients[microbedecoder]	CREATED_AS_UNMAPPED	UNMAPPED	Imported from microbedecoder (source_id=kgmicrobe.compound:2_butanol_co2); no CAS-RN or CHEBI/NCIT match. Curator review needed.
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/2-butanolCO2-edison-literature.md (local artifact — research/ is gitignored, so the findings are quoted here rather than linked). Report verdict: \| recommended action \| CURIEs discussed: CHEBI:16526. 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.
2026-08-14T00:00:00+00:00	decompose_substrate_combinations	DECOMPOSED_TO_COMPONENTS	MAPPED	UNMAPPED_0679 -> kgmicrobe.ingredient:2_butanol_co2 (FALLBACK_REGISTRY). The label enumerates its own constituents, so this is a decomposition rather than a mapping: no ontology has a term for '2-butanol+CO2', 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. 1 of 2 constituents resolve to existing MIM records via docs/data/label_index.csv; 2-butanol carries no component_id because MIM has no record for it. ingredient_type=DEFINED_MEDIUM because every constituent is a defined chemical (an unresolved name here means MIM lacks the record, not that the substance is undefined). No concentrations are recorded: the label states none.
2026-08-14T00:00:00+00:00	apply_curated_decompositions	REPLACED_COMPONENTS_WITH_CURATED		components replaced with the curated research decomposition, superseding the label split. Components taken from the curated microbedecoder research decomposition (mappings/microbedecoder_residual_research_decomposition.tsv, strategy=split): the label names its constituents. 2 constituent(s), 2 carrying an identifier. That file was produced by the research pass and never written into the records; this applies it. It resolves constituents a label split cannot — abbreviations such as PY, and named media such as BHI, state no composition to split on. ingredient_type=DEFINED_MEDIUM. No concentrations are recorded: the curated row states none.
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 2 existing component(s) (EXTERNAL_TERM, MIM_CATALOG); constituent names, identifiers, and concentrations were not changed.
