 # NOTICE:
-# Force a fresh build of drizzle-migration and assert that
-# unplugin-drizzle-orm-migrations actually replaced the `virtual:drizzle-migrations.sql`
-# import. Without this guard a layer built when the rolldown plugin silently
-# no-op'd (intermittently observed on Railway with tsdown 0.21.9 + rolldown
-# 1.0.0-rc.16) ships a dist/index.mjs that re-exports the literal `virtual:`
-# specifier, which crashes at runtime under tsx with
-# ERR_UNSUPPORTED_ESM_URL_SCHEME. `rm -rf dist` keeps this RUN's command-string
-# distinct from earlier cached variants and prevents a stale dist from masking
-# a failed transform.
+# The Rolldown adapter of unplugin-drizzle-orm-migrations intermittently left
+# the virtual import in the output on Railway. The Rollup adapter is compatible
+# with tsdown and inlines the migration data. Import the output to verify the
+# runtime contract. Do not check a generated chunk name because adapters use
+# different output layouts.
