blindness
Let an agent handle blindness respectfully, routing sudden vision loss to urgent care, supporting accessibility and rights, and giving no diagnosis.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.
