Production feed generation failed with a generic message because
NEXT_PUBLIC_SITE_URL was missing on Vercel production: buildFeedUrl calls
getCampaignInviteBaseURL(), which throws in NODE_ENV=production without the
env (intentional fail-closed), so the action catch returned 'Não foi
possível criar o feed de calendário.' and nothing was created. The local
real-flow verification (login -> agenda without filters -> header icon ->
name -> generate -> link /campanha/agenda/ical/<secret> -> iCal 200 with
the activity) proved C92/C93 work; the divergence was the environment.
Configured NEXT_PUBLIC_SITE_URL=https://pt.jorgesolla.com.br in Production
(+ checked Preview) and redeployed.
New e2e campaignAgendaFeed pins the real flow: desktop (header -> dialog
-> generate -> link responds iCal with the fixture activity) and mobile
(FAB -> sheet -> generate). The e2e fixture now owns calendarFeed rows
(createdBy NOT NULL made the campaignUser cleanup transaction abort).
AGENTS.md deploy checklist notes NEXT_PUBLIC_SITE_URL as mandatory in
Production.
Closes#483
