ValidationExceptionHandler (handles validation exceptions → 400) → GlobalExceptionHandler (catch-all → 500 in prod, full detail in dev). Each returns true to stop the chain once handled.app.UseExceptionHandler() currently runs without a SuppressDiagnosticsCallback override. In .NET 10, handled exceptions may suppress logs/metrics/events by default once an IExceptionHandler returns true. Treat this as an explicit observability decision when editing exception handling.traceId (HttpContext.TraceIdentifier), timestamp (ISO 8601), and correlationId when available. 500 errors hide detail in production.X-Correlation-ID or X-Request-ID from inbound requests, generates GUID if absent, pushes to Serilog.LogContext.
