Field notes
Sabline combines a typed language with explicit effect budgets and machine-readable run receipts. Its examples distinguish an ungranted read of ./.env from a permitted settings-file read and output-directory write, while the documentation exposes a threat model and an audit command. The site also provides an llms.txt page intended to give language-specific guidance to models before they generate Sabline code.
