The specs written alongside the session, transaction and lifecycle work still seeded and read with raw statements. They go through the ORM factories now; the few that test SQL below the ORM carry a test-sql-allow reason. The raw SQL baseline holds 177 statements in 6 files.

/**
|
|
* db/database.ts opens the connection on first use, not at import.
|
|
*
|
|
* It used to call initDb() at module load, so importing anything that reached
|
|
* it opened the database: index.ts had to defer loading the app until a
|
|
* first-boot restore had put the backup's file in place. The connection is now
|
|
* opened by its first reader (the ORM's first connect inside buildApp(), driven
|
|
* by DatabaseLifecycle), and a connection closed on purpose for a restore stays
|
|
* closed until it is reopened.
|
|
*
|
|
* The cases share the module's one connection and run in order.
