Links and GET forms to wiki pages swap the next page into .shell instead of loading a new document: the server answers boosted requests and history restores with a partial (title, page actions out-of-band, shell content). The header stays, browsers without cross-document view transitions (Firefox) no longer flash between pages, and the swap runs as a same-document view transition. Files, the editor, internal endpoints and POST forms still navigate normally. Back/Forward refetch pages (no snapshots that could predate a move or delete); the tree rail keeps its scroll position and the content column returns to where it was. Mutation redirects swap their result in the same way. Page scripts that assumed a fresh document now also run after a swap (toc, contents, companion, scroll-sync, search actions) or register once (fitness). The e2e suite now also runs in Firefox.
