Curation

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

  1. CONFIRM_UNGROUNDED 2026-08-16 · claude-opus-5

    Confirmed UNGROUNDED: no ontology term fits this concept. FOODON:03411301 'algae' kept as an xref. Non-habitat screen (#12): 'Host-associated > Algae' was grounded EXACT to FOODON:03411301 'algae', which FOODON defines as 'an informal term for a large, diverse group of photosynthetic eukaryotic ORGANISMS'. An organism is not a habitat, and because the seeder derives a GOLD child's parent from its path node, that identity also became the parent_habitats entry of 14 records under Host-associated > Algae — publishing 'is-a algae the organism group' as a broader-habitat claim 14 times over. The existing organism-identity screen could not see it: it tests ancestry against NCIT and mesh roots, and FOODON files both the organism and the material under one 'organism material' root, so there is no structural signal to test. The concept itself is real — algae as host — and is the same family as the sponge, nematode and reptile requests, so it becomes a term request with the FOODON term kept as an xref (#99) rather than an identity. (source concept habitatmech:GOLD.02383c20a7)

  2. DEFINED 2026-08-17 · claude-opus-5

    Defined as 'alga-associated environment' under ENVO:01001000 'environmental system determined by an organism'. Definition drafted from the record's deep-research report under research/habitats/ and read against it; the report's proposed wording, genus and near-miss table are the evidence. Parented to the organism root rather than the plant one: algae are polyphyletic and not all of them are green plants.

  3. SAME_AS 2026-08-24 · codex-gpt-5

    Merged into habitatmech:GOLD.02383c20a7 'Algae': the same concept under another source's name. Novel-concept merge (#183): Madin's host_algae category and GOLD's Host-associated > Algae node denote the same broad habitat, an alga acting as microbial host. Keeping both split Madin's 88 TAXON assertions from the already-defined GOLD record. Madin's flat category includes unresolved algal lineages and laboratory cultures, so its evidence remains a separate source attestation and is not pushed down to a GOLD child. The category override records Madin's own Host_associated classification rather than the seeder's prior OTHER fallback. (source concept habitatmech:MADIN.5eeeec4db2)
