Curation

What a curator decided about this record, and why. A record built from several source concepts can carry one decision per concept.

CONFIRM_UNGROUNDED 2026-08-17 · claude-opus-5
Confirmed UNGROUNDED: no ontology term fits this concept. UBERON:0000922 'embryo' kept as an xref. Life-stage review (#112): carried UBERON:0000922 'embryo' as a parent, reached by the ambiguous-leaf rule rather than the path — several GOLD paths end in the same leaf, so the ones that do not claim the term keep it as a parent. parent_habitats asserts the parent is BROADER, and a larva or embryo is a whole organism rather than a broader kind of place, so this is the same over-claim the identity cases had one level up. Kept as an xref (#99). Per the rule #114 settled: the whole host organism gets its own identity and an <X>-associated environment term; parts of a host ground to the anatomy term.

DEFINED 2026-08-31 · claude-opus-5
Defined as 'brown algal embryo' under ENVO:01001000 'environmental system determined by an organism'. Definition authored from the record's committed deep-research report under research/habitats/, read in full; the report's proposed sentence, genus and near-miss table are the evidence. No new research was commissioned. Labelled 'brown algal embryo' and not 'embryo' on the report's explicit instruction: the bare label must not be the definiendum, because in GOLD 'Embryo' is a reusable life-stage slot - the same thing MIxS models as host_life_stage - and two sibling nodes carry it under Red algae and under Fish. This is the #161 case where two records share a source label and are NOT the same concept: the differentia is already in the path, so each gets its own label and no shared-term mechanism is needed. Genus is ENVO:01001000 rather than the plant or animal branch because a brown alga is a stramenopile, neither plant nor animal; the report notes ENVO has no algae-associated environment class at all, which is the real gap here.
