Elsewhere

Proxy guidance now names the failures Claude should not retry.

What

The guidance the agent sees about making outbound HTTPS calls through the pre-configured proxy now names connection reset, unexpected disconnect and RPC failure as expected outcomes, and tells it to check the proxy status endpoint instead of retrying.

Evidence

or a transfer is cut off (connection reset, unexpected disconnect, RPC failed)

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
