/**
 * One level up from bootstrap-matches-schema.test.ts, which checks that every
 * TABLE exists. This checks every COLUMN.
 *
 * SQLite never runs the drizzle migrations at all -- runRemoteMigrations
 * throws for sqlite, and the live schema comes from hand-written DDL in
 * db/index.ts (a CREATE TABLE plus addColumnIfNotExists calls). So adding a
 * column to schema.ts and running `schema:migrations` type-checks, produces a
 * migration file, passes every repository test (their fixtures are built from
 * the schema), and still fails at runtime on the default dialect with "no such
 * column" -- breaking every write to that table.
 *
 * A grep- or token-based guard cannot catch this: db/index.ts refers to
 * columns as snake_case string arguments, never by the camelCase names the
 * schema uses. Only booting a real database and reading PRAGMA table_info
 * compares the two things that actually have to agree.
