   - Race conditions when waiting on multiple requests. Ensure that waiting checks are unique enough and don't depend on a hard order when there's a chance that telemetry can be sent in arbitrary order.
   - Timeouts or sleeps in tests. Instead suggest concrete events or other signals to wait on.
 - Flag usage of `getFirstEnvelope*`, `getMultipleEnvelope*` or related test helpers. These are NOT reliable anymore. Instead suggest helpers like `waitForTransaction`, `waitForError`, `waitForSpans`, etc.
+- Flag any new or modified `docker-compose.yml` under `dev-packages/node-integration-tests/suites/` or `dev-packages/node-core-integration-tests/suites/` where a service does not define a `healthcheck:`. The runner uses `docker compose up --wait` and relies on healthchecks to know when services are actually ready; without one the test will race the service's startup.

-# A value of 0 makes the http server behave similarly to Node.js versions prior to 8.0.0, which did not have a keep-alive timeout.

+`@sentry/effect` supports both Effect v3 and Effect v4 (beta). The integration
+auto-detects the installed Effect version at runtime, but the layer composition
+APIs differ between the two major versions, so the setup code is slightly
+different.

-The `effectLayer` function initializes Sentry. To enable Effect instrumentation, compose with:
+## Usage with Effect v4
 
-- `Layer.setTracer(Sentry.SentryEffectTracer)` - Effect spans traced as Sentry spans
-- `Logger.replace(Logger.defaultLogger, Sentry.SentryEffectLogger)` - Effect logs forwarded to Sentry
-- `Sentry.SentryEffectMetricsLayer` - Effect metrics sent to Sentry
+Effect v4 reorganized the `Tracer` and `Logger` layer APIs, so the wiring looks
