Oopts, that's obviously a bad link.

What happens is that `jsonp(res)` generates a function to send a result.
That function gets passed through `payload` called [`status`](https://github.com/tidepool-org/jellyfish/blob/bewest/clean/lib/uploads.js#L53) as the `detach` function here:
https://github.com/tidepool-org/jellyfish/blob/bewest/clean/lib/uploads.js#L53

So `detach` is actually an alias for "send information for polling needed back to client right away, and ends up being the definition of `syncTask` https://github.com/tidepool-org/jellyfish/blob/bewest/clean/lib/uploads.js#L53 with `json(res)`'s value as the callback.

Since my original intervention was so involved, I wanted to change as little as possible between the surface areas of the existing interfaces.
