Additional Information

• Fedora 42, default GNOME, x86_64, glibc 2.43
• Installed via dnf (both stable 2.1.133 and latest 2.1.143)
• strace shows only futex timeout loops, no I/O
• Workarounds tried and failed: keyring disabled, D-Bus suppressed, git repo with commit, TERM=dumb, -p flag
• Native installer also silently fails to place binary in ~/.local/bin
• interestingly "claude --version" or "claude --help" work fine
