Step 14 of v4.1 — local-development observability stack with version-pinned container images: - prom/prometheus:v3.0.1 - prom/node-exporter:v1.10.2 (textfile collector enabled) - grafana/grafana:11.4.0 - otel/opentelemetry-collector-contrib:0.115.0 Two complementary export paths from voyage hooks/scripts/otel-export.mjs: - VOYAGE_EXPORT_MODE=textfile → node-exporter textfile collector - VOYAGE_EXPORT_MODE=otlp → otel-collector OTLP/HTTP receiver (:4318) Both feed Prometheus → Grafana. Files: examples/observability/docker-compose.yml examples/observability/otel-collector-config.yaml examples/observability/prometheus.yml examples/observability/grafana-datasource.yml examples/observability/README.md Verified manifest expected_paths (5 files). docker compose config validation runs in Step 16 with proper skip-pattern when docker is unavailable.
