Three tables with CASCADE foreign keys, indices, WAL, and a real MigrationStrategy
from schema version 1. No destructive fallback, ever.
Two things needed deliberate handling. SQLite defaults foreign_keys to OFF and
Drift, unlike Room, does not enable it -- without the pragma every CASCADE is
decorative, so there is now a test that reads the pragma back. And Drift both
snake_cases columns and names row classes after tables; build.yaml sets
case_from_dart_to_sql: preserve so the schema stays column-for-column identical
to Room's, and @DataClassName keeps row types from colliding with the domain
models.
SchemaTest was instrumented and needed a device; the Drift version is a plain
unit test that runs in under a second with no emulator. 16 tests.
95 tests passing, analyze clean.
