The per-round swarm purge ran `docker volume prune -f`, which on Docker 23+ removes only anonymous volumes. A named DB volume such as mariadb_data survives `docker stack rm`, so the next round booted the prior round's database, whose root password no longer matched the freshly regenerated credentials, and mariadb failed with "Access denied for root". Use `docker volume prune -a -f` so named unused volumes are wiped too and each round re-initialises from clean state. Swarm-test-harness only; never runs in compose.

Test Utilities 🧪
This directory holds the operational side of testing in Infinito.Nexus.
These assets are meant to support confidence, not ceremony. They help the project validate real-world behavior across local development, CI environments, and deployment-oriented smoke tests. The emphasis is on practical feedback: when something breaks, the surrounding test tooling should make the failure easier to understand, easier to reproduce, and easier to clean up. 🚀
Good changes in this area usually make the test experience more:
- repeatable
- diagnosable
- environment-aware
- safe to rerun
The ideal outcome is boring reliability: contributors should be able to trust that a test run says something meaningful about the system, not just about the machine that happened to execute it. ✅
