How do I try the latest bits

Two options:
Dev channel (git checkout):
openclaw update --channel dev
This switches to the main branch and updates from source.
Hackable install (from the installer site):
curl -fsSL https://openclaw.ai/install.sh | bash -s -- --install-method git
That gives you a local repo you can edit, then update via git.
If you prefer a clean clone manually, use:
git clone https://github.com/openclaw/openclaw.git
cd openclaw
pnpm install
pnpm build
