Interesting! Does this fix the bug you reported where a situation that demanded a capability found undefined instead? And if so, how? As far as I understand this PR, no logic has changed, but some code has been consolidated?

There are 3 cases where it's pulled out - two of them are currently decoding it, but this one isnt: https://github.com/earthstar-project/willow-js/pull/23/files#diff-b6dccdeff4ac0c74bf56d6387fb90af19ebd8718059842bad86fa1ef79482b4bL683

So the functional change here is for that case to now decode it.

And yeah, this should fix the issue - when I looked at the browser debug I was getting an object with jut the bytes method - it hadn't been decoded into the auth token object with a capability field etc
