This zone covers running Avvyland in development and production: deployment topology, persistence-layer bootstrap, the async task queue, observability, load testing, and signed-off SOPs.
Deployment — production deployment topology, systemd, Nginx, TLS, hardening.
Persistence Layer — FoundationDB (production deployment) vs MongoDB (code default + local dev) — with the dual-mode feature-flag detail.
Redis Task Queue — asynq queues, callback secret, retention, scaling.
Observability — OpenTelemetry → Grafana Tempo, structured logging, trace propagation.
Load Testing — Locust at locust.k8s.avvyland.com.
SOP: Projection Model Sign-Off — gating checklist for projection-model pipeline fixes.

Code default is MongoDB (FDB_ENABLED=false in state-server/config/config.go) but production overrides this to FDB.state-server/external/mongo/docker-compose.yaml); production does not deploy MongoDB.Deployed Services for the canonical list of what runs in production, sourced from avvy/argocd.
