Notifications and updates: frames, pictures, the keyboard, Windows, and going back when a new build cannot start
The bar first, the pledge as how it is met; what is short of the bar is work owed
Security defaults: updates that install themselves, checked against the release key
Security defaults: HSTS, the Linux confinement, notifications, the update check
Shadows; the gaps found on the way; the scores
Animations and transitions; the scores
Shadow trees, modules and import maps, classes that extend the platform's interfaces; the scores
The shell: a thread for every tab; the driver and the held-time line; the harness figure
Workers, ports across them, frames that measure themselves, scripts that run once
Forms that post
The document comes on another thread, the window live meanwhile
Fetching ahead, together: the pool, the preload scanner, the rules that still hold
Pictures: height:auto over the attribute, aspect-ratio, object-fit; one pointer move a turn; the reftest score
The bookmarks manager, its import and backups; form controls: padding, placeholders, baselines, select-all; new script verbs
Bookmarks and their bar
Tabs: a closed tab comes back, a tab is copied, links open behind and beside their opener
The shell's menus: what a right click offers on a link, a picture, a selection, a field, a tab and the address bar, the main menu, the keys that work them, the popup tokens a theme may name or leave to derive, and the script verbs that drive them
Not written yet: fixed boxes follow the scroll, and have since the scroll pass moved them
Frames the reader can use, framesets, window.open, and the scripted score at 65822 of 74294

Scripting and Measurements: ranges, CDATA sections and processing instructions; 65627 / 74294 scripted subtests
An object's and an embed's documents, pictures and fallback; 16886 / 26275 scripted, 9410 / 14616 reference
A frame element's window, names fixed at creation and window reuse; 16828 / 26275 scripted
Every iframe has a window from its insertion; a document a frame cannot show leaves it an error document
A frame's window through its WindowProxy, navigation by its Location, the sandbox attribute and structured clone; 16739 / 26149 scripted, 9409 / 14616 reference
