ch15 is now an account of what's actually running, not a roadmap for
what we'd add: VictoriaMetrics + Jaeger + Grafana on 88oakappsUpdate
fronted by Cloudflare and bearer-gated nginx, vmagent in-cluster, the
internal/prom histogram set, the rollout's NetworkPolicy footprint,
the obs.88oakapps.com endpoint shape, the ~$0/700MB resource budget,
and a token-rotation runbook. The "what we still don't have" section
keeps log aggregation, alerting, and full distributed tracing as the
honest gap list.
Other touched docs:
- 00-overview: \"deliberately absent\" no longer claims we have no
metrics — calls out the cross-cluster shape instead.
- 14-deployment-process: TL;DR now points at deploy-k3s/scripts/03-deploy.sh
(full build + push + apply + obs vmagent), with the manual
kubectl-set-image flow kept as the single-service path. Notes the
IfNotPresent gotcha that bit us during the rollout.
- 16-failure-modes: adds vmagent-can't-reach-obs and Grafana-no-data.
- 18-cost: $0 line item for the obs stack on 88oakappsUpdate, with the
CX32 migration trigger.
- 17/18 README + appendix b: link the new ch15, add the obs cheat
sheet block.
