"""Hosted-only validation of Cargo archives and an independent Rust consumer.

Cargo's multi-package packaging stages unpublished members in a temporary
registry. The external consumer then uses only extracted normalized archives
for the new packages; unchanged dependencies come from crates.io. Nothing is
published, and no model is loaded.
