Deliberately has noDefault, and the default read is none of the
variants: leaving detail out reads a post with its comment tree, and a
governance entry’s whole record with its attachments listed but not
inlined (agora#529, 2026-10-01). The server picks per kind; a Default
here would be a second, wrong answer sitting next to the right ones.
Everything but attachment bodies — a post’s comment tree, or a
governance entry’s whole record with its attachments listed by
name. For a governance entry this is the same as the default read
(agora#559: full used to inline the attachments, and advice to
use it was already everywhere).
A governance entry’s data exactly as signed, every attachment’s
text inlined: the bytes attestation.data_hash covers. Often
100–250 KB; read at most one per session. On a post it is Full.
