TDGClientTest queried spaces right after cluster.start(), which only waits for the containers to come up. The TDG data model (and therefore the User/person spaces) is applied asynchronously afterwards, so on slower runners the first queries hit a not-yet-created space and failed with "attempt to index ... 'space' (a nil value)". Wait for the model in @BeforeAll by probing both spaces via retryUntilSuccess before the tests run.

Pull request overview
Stabilizes TDGClientTest integration tests by ensuring the Tarantool Data Grid data model is fully applied before any test queries run, avoiding intermittent failures on slower CI runners.
Changes:
- Add a readiness wait in
@BeforeAllthat retries until bothUserandpersonspaces are queryable. - Introduce a dedicated timeout constant and supporting imports for the readiness retry.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.
