Function cmd_trust 

pub fn cmd_trust(beans_dir: &Path, revoke: bool, check: bool) -> Result<()>

Manage hook trust status.

By default, hooks are disabled (not trusted). Users must explicitly run bn trust to enable hook execution. This is a security measure to ensure users review .beans/hooks/ scripts before allowing execution.

Arguments

• beans_dir - The .beans/ directory path
• revoke - If true, disable hooks (remove trust file)
• check - If true, display current trust status without changing it

Returns

• Ok(()) on success
• Err if file operations fail
