The release gate failed cargo-fmt. The domain that replaced the IP-based registry is longer, pushing several test assertions past the width limit, so rustfmt wanted to re-wrap them. Pure line re-wrapping — no semantic change. Caught by the pre-flight gate rather than after tagging, which is what it is for. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
