v0.47.3 Docker image metadata and MCP Registry reruns now handle the failure modes that appeared in the Claudebox, Codexbox, and Pibox release jobs. - Docker Hub short descriptions now use Docker Hub's 100 UTF-8 byte limit, rather than a character count. Both single-image and multi-image jobs keep whole Unicode characters and reject invalid direct input before authentication. - MCP Registry publishing now reads the exact public version before OIDC login. A matching existing entry is a successful no-op. A different immutable entry fails. A duplicate response is accepted only after the Registry returns the exact expected metadata.
