frank-archon (radiance, Dankserver) emits vllm:* + radiance:* (job=frank-archon).
llm-fleet.json queried only llamacpp:* and its endpoint picker selected via
label_values(llamacpp:.*), so archon - despite being scraped and alert-on
(vllm-fleet group) - had zero panels. The dashboard description also still
claimed archon was llama.cpp, which is stale.
- Fix the description: two namespaces; the $job picker is the llama.cpp pair
(dragoon/zealot); archon is radiance and gets its own section.
- Add a frank-archon row + 8 panels: vllm:* throughput, request outcomes by
finish reason, queue/preemption, TTFT p50/p95, and the radiance natives vllm
omits - decode/prefill t/s, MTP draft acceptance, engine-step timing, prefix
hit. All 14 queries verified live against Prometheus (non-empty).
Dashboards-only; the next grafana deploy provisions it.
