| 11 | * Declares a foreign-key constraint over one or more columns (class-level). | |

| 13 | * Single-column convenience stays on {@see Column}'s `foreign` flag; use | |
| 14 | * this attribute for composite FKs — or any FK needing actions/shape the | |
| 15 | * flag cannot express. `references` accepts EITHER a table name string OR | |
| 16 | * a model class-string — a model class-string resolves to its table name | |
| 17 | * through the {@see MetadataFactory} at build time (the same convention the | |
| 18 | * model itself uses), so a renamed table never breaks the FK silently. | |
| 19 | * | |
| 20 | * `referencesColumns` may be LEFT NULL when `references` is a model | |
| 21 | * class-string: it then defaults to the target model's full primary-key | |
| 22 | * column list (single or composite — a composite-PK target works out of | |
| 23 | * the box). With an explicit `referencesColumns` the arity must match | |
| 24 | * `columns` (mirroring `Blueprint::foreignKey()`); the {@see MetadataFactory} | |
| 25 | * validates names and arity at build time and emits exactly one | |
| 26 | * `Blueprint::foreignKey()` call per declaration. | |
