 ## Public installer and static distribution
 
-`python3 sdk/install-entry.py` generates the root `install` from the canonical `skills/scripts/install.py` and the independently provisioned `skills/assets/release.pub`. `--check` verifies that the committed entry is current. The generated Bash contains the complete installer, so `curl -fsSL https://git.dever.cc/shemic/dever/install | bash` does not need a Git checkout or a separate skill download. Keep download, authentication and bootstrap behavior in the Python/Rust owners; do not maintain a second implementation inside the generated file.
+Root `install` is the sole installer source. Maintain its Bash entry and embedded Python directly; there is no generator or separate skill installer. It embeds the independently provisioned public key, so `curl -fsSL https://git.dever.cc/shemic/dever/install | bash` needs neither a Git checkout nor a separate skill download. Keep archive extraction and machine activation in their existing Rust owners. Validate changes with `bash -n install` and the focused `python3 -B -m unittest discover -s test/onboarding -p 'test_install*.py' -v` suite; the tests load the actual root entry instead of copying its implementation.
