| properties | 5 | enrich_references, opsin_iupac, rdkit_post_consensus, rdkit_pre_consensus, withhold_ambiguous_mass | withhold_ambiguous_mass: removed molecular_mass, monoisotopic_mass; the flow carries 2 candidate structures, so no one mass describes it |
| altLabel | 1 | consensus_match | group_key=2,4,4-trimethylpentene||dimension=Environmental > media=Air > strata=Unknown; cas=25167-70-8; added Common Chemistry CAS names as altLabel: 2,2,4-Trimethylpentene, Diisobutene, Diisobutylene, Pentene, 2,4,4-trimethyl-; object_uuid=fo-fce21215ed16da79 |

Where several steps wrote one field, the last one won — and the log below shows the sequence.
