Curation

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

1. GROUND 2026-08-12 · claude-opus-5

   Grounded to PO:0030078 'rhizoid' (EXACT). 3 GOLD paths share this leaf and differ only in host clade. Merged onto BTO:0006474 deliberately: the structure is the same wherever it sits and the host lives in the taxon, as with feces and blood serum. Each path survives in source_attestations. Re-grounded from BTO:0006474 to PO:0030078 now that PO is vendored (#10). (source concept habitatmech:GOLD.00c5215805)
