After provisioning or re-provisioning a tester, the public URL (name.gent01.qa.grid.tf) can return 502 for a long time (seen 35 plus minutes) even though the tester is fully installed and its login gate works. Verified: the tester backend serves 302 over mycelium from other nodes, DNS resolves to the gateway node, and the on-chain name contract is clean (a single live contract, no orphans). The gateway node simply cannot reach the new VM yet. The gateway proxies per request, so re-deploying the gateway does not help; it is purely the gateway-node to fresh-VM mycelium route propagating. We should confirm whether this reachability can be sped up or pre-warmed (a ready VM pool would sidestep it). Separately, redoing a gateway for an existing user is fragile today: it needs the old name contract cancelled and the old gateway deleted by hand, compounded by the nonce issue (lhumina_code/hero_compute#132) and the empty-fqdn issue (lhumina_code/hero_compute#133).
