Picks the mark from 95c93f9 over the one I drew: at the 16–18px the dock actually renders, a solid fill reads and an outlined page does not, and pairing with pdf-editor's red badge makes the two editors obviously a set. It moves into icon.svg rather than living only as a data URL in the manifest, so make-icons.mjs keeps deriving the PNGs and addon.json's copy from one drawing. Same picture as before, one source instead of three places to forget.

Word editor — a Theseus extension
Opens, edits and saves Word documents (.docx) in a full Theseus tab, and
exports them as PDF.
Saving comes in three shapes. Save drops a copy in your downloads until the
document has a home; Save as… opens a real file dialog where the extension
you type — .docx or .pdf — decides the format, and from then on Save writes
straight to that file; PDF is the one-click export. PDFs are rendered by
Chromium's own print pipeline from lib/doc-css.js, the same stylesheet the
editor displays, on the paper size the document itself specifies — so the
export matches the preview rather than being a second opinion about it.
It is a first-party extension: written here, signed with the Silent Mode
operator key, and updated over the channel at
theseus.x/extensions/docx-editor/ like every other add-on Theseus ships.
It does not go through the community catalogue, which is for extensions
published by whoever owns a BNS name.
It ships inside Theseus, so a fresh install already has it and Settings lists it under Built into Theseus; the channel above then updates it between releases without waiting for one. That is the same arrangement as screenshot, aegis and pdf-editor, and it is what gives a user their first copy at all — Settings can only install from the community catalogue, so an extension that is neither bundled nor catalogued has a working update channel and no way in.
The cost is about 400 KB compressed in the installer, most of it the vendored editor libraries.
The icon
icon.svg is the one drawing. npm run icons rasterises it to
icon-16/32/48/128/256.png and writes a minified copy into addon.json's
icon field, which is what the dock button and the catalogue card read — so
there is never a second version to keep in step.
It is a blue document badge, paired with pdf-editor's red one so the two editors read as a set in the dock — a solid fill stays legible at the 16–18px the dock actually renders, which an outlined page does not.
Deliberately not Microsoft's Word icon: their mark is a blue sheet carrying a white W, and dressing our extension up as theirs would be both a legal problem and a dishonest one. A folded-corner page is the universal document glyph, and "DOC" is the file format rather than anyone's trademark.
Building
The vendored libraries (mammoth, ProseMirror, docx, JSZip) are bundled by a build step that lives outside this folder, because mammoth needs local patches before it can carry everything the editor edits:
cd ../../addon-build/docx-editor
npm install
npm run build # writes vendor/docx-vendor.js here
npm run icons # re-rasterises icon.svg after editing it
vendor/docx-vendor.js is committed, so the extension is installable straight
from a checkout; re-run npm run build after touching anything under
addon-build/.
Publishing
The full recipe is in docs/ADDON-UPDATES.md; the short version, signed with the operator key and always from a clean copy of the commit rather than the working tree:
git archive HEAD TheseusNavigator/extensions/docx-editor | tar -x -C <clean>
node scripts/sign-addon-update.mjs <clean>/TheseusNavigator/extensions/docx-editor https://navigate.st/bns/theseus.x/extensions/docx-editor "$USERPROFILE/.silentmode/ops/addon-update-key.pem" --out out/
node ../Argus/src/lib/sia-upload.js out/docx-editor-<version>.tar.gz bns/theseus/extensions/docx-editor
node ../Argus/src/lib/sia-upload.js out/updates.json bns/theseus/extensions/docx-editor
The channel lives on Sia only — nothing goes to the VPS filesystem — and is
served through the gateway at https://navigate.st/bns/theseus.x/extensions/.
A first release has no updates.json to prepend to, so it ships one holding
just its own entry. Versions must increase.
Testing
Three levels, all re-runnable, all from ../../addon-build/docx-editor:
node test/roundtrip.mjs # the built-in fixture
node test/corpus.mjs <folder of .docx> # real documents
node ../../../scratchpad/verify-docx-editor/drive.mjs # a real Theseus, over CDP
The last one installs this folder into a throwaway profile the way the community channel would, and is the only one that catches browser-only breakage.
What survives a round trip, and what doesn't, is written up in ROUND-TRIP.md. Read that before promising anyone a Word feature.
