This update brings the macOS Scaleway runner cache onto the same per-account Kura mesh as the Linux fleet, with a fr-par-local hot path.
- Faster, local cache reads for macOS runners. The macOS Tart VMs now read and write cache directly from a per-account cache node inside Scaleway fr-par over a Private Network NodePort, instead of crossing the WAN to a Hetzner node. The controller restamps the endpoint automatically if the cache pod moves to another node.
- Background cross-region replication keeps caches coherent. The fr-par cache node and the account’s Hetzner nodes form a private, per-account peer mesh with mutual TLS and bandwidth limits, so cache data stays in sync without adding latency to the runner hot path.
- Per-account CA isolation. The controller now maintains a separate certificate authority per account for mesh peering, so pods from different accounts cannot authenticate to each other over the replication plane.
