Models a social network's home feed and what readers do around it: a virtualized feed that loads more stories as it scrolls, a post dialog with threaded comments and a composer, a profile route and back, a search typeahead and the header menus. It also runs the instrumentation such apps attach to every interaction: error-guard wrappers, auto-tracked events that are batched, compressed and checksummed for upload, impression tracking, interaction timing and feature-gate exposures. Original React 19 + Vite + Tailwind code with deterministic, server-free fixtures (an in-page server streams chunked responses) and no third-party assets. Experimental, so it is off by default and does not affect the official score. Steps wait on window events the app fires once an interaction has committed. After clicks and keystrokes they also await a microtask, because React 19 commits discrete updates from a microtask, which a step-dispatched event only reaches once the step yields.
Output of `npm run build` in suites-experimental/social-network. Build artifacts only, so it can be dropped and regenerated whenever the source commit below it changes.

WebKit allows 100 pushState/replaceState calls per 10 seconds and counts them on the main frame, so suites that ran earlier in the harness can use up the budget. The router's pushState then threw a SecurityError before the state update, and OpenPostDialog waited forever for its event. The steps never go back or forward, so drop the History API entirely.

SocialNetwork-React, an experimental workload. It's an original React 19 + Tailwind app that models a social feed: a virtualized feed, a post dialog with threaded comments, profile navigation, search typeahead, and analytics running on every interaction.Steps: refresh the feed, scroll and load more stories, expand truncated stories, open a post dialog, expand replies, change comment order, load more comments, type a comment, close the dialog, open own profile, go back to the home feed, search typeahead, open the header menus.
