feat(docx-editor): edit Word documents without quietly eating what Word put in them A .docx editor is easy to write badly: read the file into HTML, let someone edit it, write a fresh document back, and hand them a file that lost its headers, its page size and half its formatting without ever saying so. Three things keep this one honest. The reader doesn't use mammoth's HTML. mammoth's converter is deliberately semantic, and HTML has nowhere to put a run's colour or a paragraph's line spacing, so it drops them — and those are controls this editor puts in the ribbon. Taking its parsed document model instead means what the ribbon offers is what the file can actually carry. Six properties mammoth's model didn't keep are added by build-time patches, each asserting its anchor so an upgrade that moves the code fails the build rather than shipping a lossy reader. The writer rebuilds the body but carries the rest of the package across: headers, footers, footnotes, endnotes, the document's own style catalogue, its theme and its page setup, with relationship ids and content types re-wired. Word features the editor can't model are still lost, so they are detected when the file opens and named in a banner before anyone edits. Tracked changes get their own gate. mammoth renders insertions as ordinary text and drops deletions, so saving would accept every pending revision without Word ever asking. Such a document opens read-only until the user says that is what they want. Verified over 66 real documents: 65 round-trip with an identical model and a structurally valid package, the one exception being a 7 MB WMF picture, which no browser can display and the writer cannot emit. Also driven end to end through a real Theseus over CDP — sidebar, ribbon, typing, save, reopen.

refactor(docx-editor): ship it as a community extension, not part of the browser A .docx editor is a megabyte of vendored library. Bundling it would charge that to everyone who wanted a browser, including the people who will never open a Word document in it. So it leaves the build: out of bundled-addons/, out of extraResources, absent from a fresh profile. It arrives the way anyone else's extension does — Settings › Extensions › Community, from the catalogue the gateway builds, and listed on theseus.x/extensions alongside everything else published there. That also means it is signed by the owner of a BNS name rather than by the operator key, which is the right trust story for something that isn't part of the browser. `npm run pack` produces the tarball the publish page takes; the signature needs the publisher name's wallet, so it isn't something the repo can do. The end-to-end test now installs the extension into a throwaway profile the way the community installer would, and asserts up front that a fresh profile doesn't already have it — the bundling is what was being removed, so it is worth a test that would notice it coming back.
