rb-node-2 says hi

A small worker node, freshly racked. Not serving an app yet — still bringing up the infrastructure side.

// planned role

This node is the third worker in the lab-east sidekiq pool. It pulls background jobs from the staging redis (mailers, csv exports, image thumbnailing, occasional pdf rendering). No public HTTP listener is configured — that lives behind a separate proxy on a different VLAN, and it never terminates traffic on this address.

• sidekiq concurrency: 25 threads (memory-tuned for jemalloc)
• queues: default, mailers, exports, low, scheduled
• upstream: redis-staging-1.lab.example:6379 (sentinel-managed)
• log shipper: vector → loki-lab (json lines)
• metrics: yabeda + prometheus, scraped on :9394

If you've landed here from a stale bookmark, the app that previously lived at this hostname has been retired or never deployed at all. No redirect is configured — by intent. Anything that needs to find it should be using service discovery via consul, not raw hostnames.
