TPAC agenda: Monday (6th) & Tuesday (7th)

Hey folks. Looking forward to TPAC next week, it'll be a *busy* and
interesting one!

As a heads up, our tentative agenda is outlined in the following doc:
https://docs.google.com/document/d/1s7S1gpAp4nzFclIHN_nxN84Rfz-LMV554gf2-8aXR10/edit

Please take a look at the relevant background links (explainers, design
docs), and please feel free to chime in on the doc if you see anything
missing, slots that need to be shuffled, etc.

Cheers.
