■ Challenge detected

Given a source bundle, entry file, command, and failure predicate (exit code and/or stdout/stderr patterns), runs a deterministic delta-debugging reducer in a network-isolated sandbox and returns the reduced bundle and entry that still reproduce the failure, plus a replay script and run log. Scoped to a local minimum under the passes listed, never a proof of global minimality.
