Do not move to dashboard upload while a preflight failure remains.\n\n## Update invariant\n\nWhen updating an existing published plugin, preserve its plugin ID, package name, developer identity, public metadata, branding, and directory identity. Only upload a newly versioned package after all checks pass.\n"
