-- 0027_migration_requests — customer-initiated migration intake.
-- The dashboard wizard at /dashboard/projects/new/migrate writes one
-- row per source-platform import request. During beta, every row is
-- triaged by an operator via /dashboard/admin/migrations and either
-- handled by the (forthcoming) automated adapter pipeline or migrated
-- by hand for free. Once the adapter for a source ships, status
-- transitions through `scheduled` → `in_progress` → `completed`
-- without an operator in the loop.
