The package override forces "drizzle-orm": "catalog:".packages/core/script/migration.ts is a Bun migration generator/checker. Its fixed paths are packages/core/schema.json (snapshot), packages/core/src/database/migration (tsDir), packages/core/src/database/migration.gen.ts (registry), and packages/core/src/database/schema.gen.ts (schema); CLI options are boolean --check and string --name.packages/core/script/migration.ts calls generate(): it creates an opencode-core-migration- temporary directory with incremental and full outputs, copies packages/core/schema.json to incremental/baseline/snapshot.json, runs Drizzle incrementally with the optional migration name, rejects more than one generated migration, writes a new formatted TypeScript migration to packages/core/src/database/migration/${name}.ts unless that file already exists, updates packages/core/schema.json from the generated snapshot, generates the complete schema into packages/core/src/database/schema.gen.ts, regenerates packages/core/src/database/migration.gen.ts, and recursively removes the temporary directory in finally.packages/core/script/migration.ts --check calls check(): it generates an incremental migration from the baseline and throws Core schema has ungenerated database migrations. Run \bun script/migration.ts` from packages/core.if any migration appears; regenerates and byte-compares the full schema, throwingCurrent database schema is stale. Run `bun script/migration.ts` from packages/core.on mismatch; regenerates and byte-compares the registry, throwingDatabase migration registry is stale. Run `bun script/migration.ts` from packages/core.on mismatch; and always recursively deletes itsopencode-core-migration-check-` temporary directory.drizzle() helper in packages/core/script/migration.ts writes a temporary ${path.basename(output)}.config.ts that imports packages/core/drizzle.config.ts by file URL and overrides out; it runs bun drizzle-kit generate --config ${config} plus ["--name", name] when a name exists, with working directory packages/core.packages/core/script/migration.ts scans */migration.sql, extracts and sorts directory names; generatedSql() requires exactly one full-schema migration and throws Expected one full schema migration, found ${generated.length}. otherwise; typescriptMigrations() scans *.ts in packages/core/src/database/migration, strips extensions, and sorts names.Effect and DatabaseMigration, export { id: name, up(tx) { return Effect.gen(...) } } satisfies DatabaseMigration.Migration; generated full-schema modules omit id and satisfy Omit<DatabaseMigration.Migration, "id">. SQL is split on --> statement-breakpoint, trimmed, empty statements removed, and each statement rendered as yield* tx.run(...).renderRun() in packages/core/script/migration.ts replaces tabs with two spaces, emits one-line SQL inline and multiline SQL in an indented template literal; escapeTemplate() escapes backslashes, backticks, and ${. Generated TypeScript is formatted with Prettier’s typescript and estree plugins using semi: false and printWidth: 120.renderRegistry() in packages/core/script/migration.ts emits parallel dynamic imports via await Promise.all([import("./migration/${name}"), ...]), maps each module to .default, and constrains the result with satisfies DatabaseMigration.Migration[].
