description	Verifies OpenTelemetry, health endpoints, and service discovery defaults in Aspire-hosted services
compatibility	opencode
metadata	{"domain":"observability"}

What I do

• Validate baseline service defaults for telemetry and health.
• Check instrumentation assumptions after API/Web changes.
• Provide a quick sanity checklist for Aspire dashboard visibility.

Checklist

1. Confirm AddServiceDefaults() is used in service startup.
2. Confirm default health endpoints are mapped in development.
3. Confirm HTTP client service discovery is preserved.
4. Confirm traces/metrics/logs are still emitted.
5. Confirm no change accidentally suppresses critical diagnostics.

Working examples from this repo

• Service defaults in API: AspireChat/AspireChat.Api/Program.cs calls builder.AddServiceDefaults() and app.MapDefaultEndpoints().
• Service defaults in Web: AspireChat/AspireChat.Web/Program.cs calls builder.AddServiceDefaults() and app.MapDefaultEndpoints().
• Service discovery HTTP clients: AspireChat/AspireChat.Web/Program.cs sets typed client BaseAddress = new("https://api").
• Test-time health wait: AspireChat/AspireChat.Tests/WebTests.cs waits for WaitForResourceHealthyAsync("web", ...) before assertions.
