 - Since we're adding a new sink, we add a tuple to the **sinkModel** extensible predicate.
 - The first column, **"fabric"**, identifies a set of values from which to begin the search for the sink.
   The string **"fabric"** means we start at the places where the codebase imports the package **fabric**.
 - The second column is an access path that is evaluated from left to right, starting at the values that were identified by the first column.
 
-  - **Member[api]** selects accesses to the **api** package.
-  - **Member[sudo]** selects accesses to the **sudo** function in the **api** package.

   - **Argument[0]** selects the first argument to calls to that function.
 
 - **command-injection** indicates that this is considered a sink for the command injection query.
