It's called Catalyst, not Marzipan, which is pushed back on a little. Podcasts is cited as fulfilling this (is it replacing a Mac app? Stephen gets away with this a bit) and they say that Messages might now be a Catalyst app, but in fact it isn't.
The permissive grading may be due to the other hosts not wanting to get too picky when it comes to grading later picks.
The watch version of Home did get redesigned, so this pick is deemed technically correct. Myke made the same pick in the Upgrade Draft, but didn't get credit there as it was in the iOS and iPadOS section.
"Heavy on Siri integration, framework for pro apps to talk to each other"
Ungraded: probably a migration tool from version 1, the App Store version might be kept around for a while
Some contention during grading about pro apps talking to each other leads to clarification that the entire pick must be true, but this one is deemed close enough.
A week after grading, there is some controversy from the listeners and Federico, as iWork did get updated (well, slightly, a few basic Shortcut actions were added), it just wasn't mentioned in the keynote. Stephen proposes a placating half point, but Myke stands firm that "there are no half points around here." This seems to be the last time that half points were ever considered for a pick.
"(how do we decide major? — on stage at WWDC or we decide past that)"
Ungraded: "some features that Federico would like to see", the actual features that Federico talked about were not recorded in the document, but were: a new, more flexible design, easier and faster to add dates and notes, tags, saved searches, better Files integration
"Be multilingual and support multiple languages at the same time."
"Support multiple modalities – e.g. text input, voice input, or image attachments in the same conversation."
"Display content from third-party apps inline based on a new developer framework."
If the overall pick about a "Siri app" is wrong, all the details will be counted as wrong as well. But that won't be a problem because Federico thinks that this approach is "so obvious".
