Prometheus and OpenTelemetry were unused overhead that added complexity without providing practical value for this project. OpenTelemetry in particular was only partially integrated — the SDK was never initialised, meaning spans were silently discarded. Removed: - prom-client, @opentelemetry/sdk-node, @opentelemetry/auto-instrumentations-node deps - src/metrics/ (MetricsService, MetricsController, MetricsModule) - src/telemetry/ (TelemetryModule stub) - src/common/interceptors/tracing.interceptor.ts - Secondary internal NestJS app on port 3001 (main.ts) - telemetry config block (config/configuration.ts) Updated: - BrewService / BrewController: removed MetricsService injection and counter calls - BrewModule: removed MetricsService provider - AppModule: removed TelemetryModule import and TracingInterceptor provider - Unit tests: removed MetricsService mocks and metric-specific assertions - E2E tests: removed MetricsModule setup and internal metrics server assertions - article_submission.md: removed Prometheus/OpenTelemetry bullet point
