Evidence and provenance
Every sentence on this site is bound to a named source in our claims register, and the site cannot be published until each one is approved. In our research stack an answer carries its sources, their dates and what the search did not cover.
Execution and data boundaries
Patra's document core performs no network I/O, proven by tests that block sockets and deny the network at the operating-system level. Karta runs commands in a sandbox with the network off by default. Where a system cannot yet keep data inside your environment, we say so.
Human authority
People set what a system may do. Karta stops at protected paths until a person approves, and each approval is bound to the action it approves; in ChangeProof an approval counts only for the exact plan the reviewer was shown.
Execution and refusal
The research API declares which components ran and refuses an unapproved downgrade. When evidence is insufficient, it abstains and shows what it searched.
