📝 WalkthroughWalkthroughThe change adds opt-in PostHog error tracking and OpenTelemetry log export. Dashboard middleware captures exceptions and HTTP completion data. Dashboard PostHog settings, demo environment variables, dependencies, documentation, and observability tests are updated. ChangesApplication observability
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to This change enables opt-in browser and server telemetry for the demo. It should not merge until telemetry is restricted to HTTPS, since an HTTP endpoint could expose exported logs and credentials; the remaining test-isolation and documentation issues are lower-impact but should also be corrected.

The standard docker-compose.yaml builds docker/Dockerfile.anomstack_dashboard, which copies only selected anomstack files and does not include anomstack/observability.py, so this unconditional import terminates the dashboard with ModuleNotFoundError before Uvicorn can serve anything. That image also installs only requirements-dashboard.txt, which lacks the new PostHog/OpenTelemetry dependencies needed when observability is enabled; update the standalone dashboard image and its requirements alongside this import.
Useful? React with 👍 / 👎.

Document the unmatched route-label fallback.
The middleware uses getattr(route, "path", "unmatched"), and the current demo can emit unmatched. This sentence says that HTTP logs include a route template without stating that fallback.

The PR objectives identify completed Replay Vision analysis as unverified, but this text states that scanners emit Signals as confirmed behavior. Qualify the statement so operators do not treat unverified demo output as confirmed.

Reset the cached observability client before this assertion.
configure_observability() returns the existing module-level _client before it evaluates the environment. If another test initializes observability first, this test can fail even when POSTHOG_OBSERVABILITY_ENABLED is unset. Reset _client with monkeypatch or add a fixture that restores the module state.

The live demo now sends browser analytics, replay data, exceptions, and dashboard application logs to the Deepwell dev PostHog project (148051), supporting self-driving dogfooding.
