-- Status: DO NOT RUN prisma db push --accept-data-loss
--
-- PROBLEM:
-- prisma db push detects drift and wants to DROP+RECREATE:
--   - VisitorProfile (19,336 rows)
--   - HouseholdCluster (2,741 rows)
--   - AdClickEvent (1,524 rows)
--   - AttributionPath (841 rows)
--   - TrackedSession columns: channelGroup, fbclid, gbraid,
--     gclid, utmContent, utmTerm, wbraid
--
-- All models and columns ARE present in prisma/schema.prisma.
-- The drift is from structural differences (types, constraints,
-- indexes) between the schema file and production.
--
-- SOLUTION: Use safe-migration.sql for additive changes only.
-- Then run `npx prisma db pull` to sync the schema file with
-- the production database state.
--
-- To generate the actual diff SQL, run from a machine with
-- DATABASE_URL:
--
--   npx prisma migrate diff \
--     --from-schema-datasource prisma/schema.prisma \
--     --to-schema-datamodel prisma/schema.prisma \
--     --script
