D002 - A refusal is not a failure

Status: decided Date: 2026-09-26

pros-link reports a target that understood and said no as Error::Rejected, and a target that answered in a shape this crate cannot read as Error::Unintelligible, carrying what was said. Neither is a broken link.

Why: the two call for opposite next actions. A rejection is usually the operator's path and nothing is broken; an unreadable answer is usually this crate being wrong about the server, and what was said is the only useful thing to report.

Rejected:

• Folding both into a connection failure: a caller then reconnects to fix a typo.
• A finer set of variants: distinctions that do not change what the reader does next.
