| 11 | * Fixture: a Lambda that owns a REST API and serves two routes through the |
| 12 | * `RestApiEventSource` (`onRestApiRoute`) binding. The event source |
| 13 | * materializes the `Resource` chain, `AWS_PROXY` `Method`s, and the invoke |
| 14 | * `Permission`; the `Deployment`/`Stage` below are ordered after them via |
| 15 | * the API's binding contract. |
| 16 | * |
| 17 | * Deliberately does NOT `yield*` any `api.*`/`stage.*` outputs: the API's |
| 18 | * full `create` settles only after every bound child (including the |
| 19 | * `Method`s that reference `host.functionArn`), so awaiting those outputs |
| 20 | * inside the host's own effect would deadlock the plan. The test discovers |
| 21 | * the REST API id out-of-band by its stack, stage, and logical-id tags. |
