Stand up the cluster's first trace store + OTLP ingress so tripit's OpenTelemetry spans (Phase 1, already live in prod) export and correlate with logs: - Grafana Tempo (single-binary, filesystem on proxmox-lvm 20Gi, 30d) - OTel Collector (contrib; otlp -> redaction deny-list backstop -> batch -> tempo) - Grafana: a Tempo datasource + an ADDITIVE trace_id->Tempo derivedField on the Loki datasource (no uid change, so existing dashboards are unaffected) - tripit deployment: LOG_FORMAT=json + OTEL_EXPORTER_OTLP_ENDPOINT -> the Collector Additive (new helm releases; Loki/Prometheus/Grafana untouched). Offline 'terraform validate' clean; full plan+apply runs in CI (locked git-crypt blocks a local plan as non-admin). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
