§3.2.5: clarify that advance_sections are engagement-scoped (not
artist-scoped). One master artist with two engagements advances each
trajectory independently. Drop the prose section enumeration that
predated the AdvanceSectionType enum and conflated section names
with section types — section type is the enum, name is a free string,
default seeds land in Session 3 with ArtistAdvanceDefault.
§17.3: footnote on the artist_advance row documenting engagement
context resolution — ArtistResolver::fromPortalToken looks up
artist_engagements.portal_token, returns the master Artist as subject,
populates form_submissions.event_id from the engagement.
