#5104 "CI integration lane connects to another repo's Postgres when two integration jobs share the runner". Run 8358 took task 31950's Postgres (another repo's integration job) with `--filter name=integration | head -n1` and every test failed to connect. Read this job's GITEA-ACTIONS-TASK-<n>- prefix from its own container and require exactly one Postgres under it. (Docker ORs repeated name= filters, so the old one is dropped, not kept.)
