For the doc items in the exec sheet, we have a way of incorporating them into spells as public constants, you can refer to this example from the archives. Since this is top level it must be declared as constant or else the spell cannot be cast. In this case we have multiple doc hashes, so a more specific variable name such as COINBASE_DOC or JATDAO_DOC (examples of var names, I just make them up) might be useful.

Link change is fine. Content hash appears to be unaltered.

Hash updated for me and is now 0xcb6486208b3cd076038392e547db55b56f4221ffd966ee1aa6573e6c86ec21d2. Just confirming this is the same on your end.
