Timeouts look like client bugs until you see the cluster

Payments.Authorize timed out after eight seconds is easy to blame on the caller. Region tags and retry metadata often show a regional capacity problem instead.

If the caller already left, you never get that nuance. You only get a lost evaluation.

Capture on the middleware boundary

API middleware probes record the method, deadline, and environment. Pair them with an inbox reply that asks what the developer was trying to complete.

That qualitative note plus the stack is what turns a timeout into a trustworthy ticket draft.

Separate taxonomy from raw volume

gRPC failures should not drown in a generic 5xx bucket. Taxonomy and surface breakdowns show whether CLI, web SDK, or API middleware is burning hottest.

Capture the failure before they leave

Capture the failure before they leave. Book early access or talk to sales, then install @aethellayer/sdk when you are onboarded.
