…-view (TRA-902) Final TRA-902 activation piece: deliver the reader-feed config to the backend as Deployment env vars (GitOps-durable; ArgoCD self-heals the backend, so ad-hoc `kubectl set env` would be reverted). The backend (platform #455/#456) stamps these into index.html → window.__APP_CONFIG__.readerFeed; the SPA's Live Reads tab subscribes the browser to the broker over WSS. - helm/trakrf-backend: add a `readerFeed` values block + a conditional env block (gated on readerFeed.url, mirroring the mqtt.host trigger). READER_FEED_MQTT_URL /USERNAME/TOPIC as config; READER_FEED_MQTT_PASSWORD via secretKeyRef from trakrf-mosquitto-auth/frontend_password (out of git). Off by default. - argocd/root: per-env `readerFeedEnabled` flag (preview=true, prod=false) + GKE-only inject of readerFeed.url = wss://mqtt.<env>.gke.trakrf.id:8084/mqtt. Pairs with #148 (broker WSS listener + frontend-readonly read-only ACL). The creds land in PRE-AUTH index.html (public) → least-privilege subscribe-only. prod stays off until the multi-tenant cross-org read gate is closed (TRA-902 comment). Verified: helm template — preview renders READER_FEED_MQTT_* (URL/USERNAME/TOPIC + PASSWORD secretKeyRef); default/prod/aks render none; root gke injects the preview URL only; lint + root render pass.

helm/ chart change → ArgoCD auto-syncs; backend rolls (
maxSurge:0, single-pod) and serves the reader-feed config. Thefrontend-readonlyuser + WSS listener are already live (#148 + activated). After merge I'll confirm the backend carries the env + ping platform to validate end-to-end (DevTools__APP_CONFIG__.readerFeed, Live Reads tab).🤖 Generated with Claude Code
