# Publish-only migrations

A package that publishes its migrations with a timestamp must not also auto-load them — doing both runs both copies and fails on a duplicate table, a bug that hit three of our packages. Two package-only expectations pin the publish-only policy against a service provider:

```php
expect($providerClass)->toNotAutoLoadMigrations(?string $migrationsDir = null);
expect($providerClass)->toPublishMigrationsTimestamped(string $tag, int $count);
```

```php
it('publishes its migrations instead of auto-loading them', function (): void {
    expect(PasskeysServiceProvider::class)->toNotAutoLoadMigrations();
    expect(PasskeysServiceProvider::class)->toPublishMigrationsTimestamped('passkeys-migrations', 3);
});
```

- toNotAutoLoadMigrations — the package’s migrations directory (resolved from the provider by reflection, or passed explicitly) must not be registered with the migrator.
- toPublishMigrationsTimestamped — the tag must publish exactly $count sources, each to a database\_path('migrations/<Y\_m\_d\_His>\_<name>.php') destination.

Both only make sense against a package service provider, so they are package-only — an app has no provider to point them at. The provider must be registered in the test’s app through packageProviders(): toNotAutoLoadMigrations fails on a provider that never booted, since it could not have registered anything and would pass for free. Static mirrors: Assert::doesNotAutoLoadMigrations() and Assert::publishesMigrationsTimestamped().
