Thanks to Lucas for scribing this week!

We talked about a number of different topics, e.g.:
- how to trust local/remote/verified/unverified/etc. DID resolution (see
#44 <https://github.com/w3c-ccg/did-resolution/pull/44>),
- how to use proofs and metadata at different stages of DID resolution,
- how to treat deactivated DIDs (see #5
<https://github.com/w3c-ccg/did-resolution/issues/5>),
- caching (see #10 <https://github.com/w3c-ccg/did-resolution/issues/10>),
- resolving DIDs after a fork or other failures of the underlying ledger
(see #43 <https://github.com/w3c-ccg/did-resolution/issues/43>)

*Next call will be on November 7th.*
