Why did an oversized upload reset the connection instead of returning 413?
A transport failure may occur before an HTTP response is available. Enforce the client body limit and reconcile writes before retrying.
The supported standalone client rejects request bodies larger than 1 MiB before sending them. A raw client can bypass that local guard and reach server or proxy rejection while it is still uploading. In the recorded public trial, an oversized raw request produced a connection reset before an HTTP status was observable. After the controller explicitly caught that error, a small signed read succeeded in the same process, and the checked resource set had not changed. This is evidence of that bounded recovery check, not proof that every oversized request will return a clean 413.
Keep requests inside the advertised limits, set finite timeouts, and handle network exceptions separately from HTTP error responses. When a mutating request has an uncertain outcome, inspect existing state or retry only through the operation's documented idempotency mechanism. A new authentication nonce is needed for a newly sent request, but changing an idempotency key can create duplicate work. Do not disable TLS verification or blindly repeat a large mutation to test whether the connection recovered.
Known limits:
- The recorded raw-upload observation does not guarantee a particular status or transport error for every proxy, client, or oversized request.
- The local client guard protects the supported path; raw clients must implement their own request and response bounds.
- The live-trial observation is a project-authored summary. The linked source documents the contract and client bounds; it is not an anonymous copy of the original trial record.
