AGENTS.md: the rule set is now two groups (llm-fleet + vllm-fleet) and a
Loki datasource is provisioned beside Prometheus.
Observability.md: current-state census refreshed (three LLM targets up,
two rule groups, Loki datasource); logs still carry no data.
Alloy.md: replace the 'wrong glob' theory with the proven cause - a
rootless container cannot read the 0640 systemd-journal files (a rootless
busybox read returns DENIED), and rootless quadlet logs land in the user
journal the system-only source never reads. Closing it is a
permission/architecture decision, not a config glob.
Adds shared/grafana/provisioning/datasources/loki.yml at http://loki:3100
so logs are readable through Grafana Explore. Loki ships no web UI of its
own and the guarded vhost serves only the API; this is the human surface.
radiance exports vllm:* metrics (verified on the live endpoint), not
llamacpp:*: nothing in llm-fleet could ever see frank-archon. Add a
vllm-fleet group - 1 recording + 4 alert (queueing, prefix-cache
collapse, preemption, p95 time-to-first-token) keyed to vllm:*.
Split the observability seam so llm-fleet rules bind llamacpp:* and
vllm-fleet rules bind vllm:*, and neither may evaluate the other's
namespace. Drops the retired no-metrics-for-archon doctrine the seam
still asserted and the vacuous namespace grep.
