A holder that failed leaves a version to publish again by hand: said numbered again while the build is held, built again under the same number when its file is gone, numbered anew after a published; refused for other bytes. The floor is asked again by hand; a branch's tagged versions are removed through each seat's remove, per repository. Claude-Session: https://claude.ai/code/session_01JG73KJNrH5EgFXMKKYSrig
