<smaug> hi rniwa !

where we're heading

Ilya: the architecture came through evolution
... rather than thinking through from the start
... (looking at Level 1 picture)
... we're been trying to refactor things since
... we've pushing Resource Timing L1 through CR

Todd: RT L1 is implemented everywhere except Safari

Plh: a little bit of randomness in L1, since we don't define precisely how many resources will show up and how exactly (like multiple initiators)

[Ilya shows L1 and L2 at the same time]

[side discussion on running wptserve]

[Ilya goes through the changes of L2*)

[Q3-Q4 deliverables]

Ilya: I'd like to wait until L3 before moving Resource Timing to Fetch
... for L2, we need to resolve globalOffset for HRT, and missing resources in RT2

Plh: (earlier) we'll ship all the timeline L2 together

Ryosuke: we'll need to identify all the things missing in Fetch first

RESOLUTION: Publish a FPWD of Page Visibility 2

Ilya: for Beacon, let's keep as-is for L1
... and do the rewriting for L2

Todd: I'm motivated to close some of the discussions on L2 quickly

RESOLUTION: Push Beacon L1 to CR
