+- `src/Database/Models/Tenant.php`
+- `src/Database/Models/Domain.php`
+- `src/Contracts/Tenant.php`
+- `src/Contracts/Domain.php`
+- `src/Database/Concerns/*`
+- `assets/migrations/*`
+
+## Default Tenant Model
+
+- Table: `tenants`
+- Primary key: `id`
+- Uses `VirtualColumn`, `CentralConnection`, `GeneratesIds`, `HasInternalKeys`, `TenantRun`, `InitializationHelpers`, `InvalidatesResolverCache`.
+- Dispatches tenant lifecycle events.
+
+## Default Domain Model
+
+- Unique `domain` column.
+- Belongs to configured tenant model using `Tenancy::tenantKeyColumn()`.
+- Uses `CentralConnection`, `EnsuresDomainIsNotOccupied`, `ConvertsDomainsToLowercase`, `InvalidatesTenantsResolverCache`.
+
+## Single-Database Traits
+
+- `BelongsToTenant`
+- `FillsCurrentTenant`
+- `TenantConnection`
+- `CentralConnection`
+- `HasScopedValidationRules`
+- `RLSModel`
+
+## Rules
+
+- Custom tenant models must implement `Stancl\Tenancy\Contracts\Tenant`.
+- Custom domain models must implement `Stancl\Tenancy\Contracts\Domain`.
+- Preserve resolver cache invalidation behavior when replacing models.
+- Use tenant scoping traits consistently for single-database tenancy.
+- If auto-increment tenant IDs are used, update config and migrations together.
