We've completed the M4 milestone by introducing a self-contained observability dashboard at /_anvil and adding support for OpenTelemetry GenAI semantic conventions. The new dashboardMiddleware provides a zero-dependency view into your traces, while traceToOtelSpans and the new OTLP/HTTP exporter allow for seamless telemetry integration with your favorite collectors. We also improved the dev loader to ensure singleton trace stores are shared reliably across route files during development.
