Moving it out of the build left it with no way in. Settings can only install from the community catalogue, so a first-party extension that isn't bundled has a working update channel and no first copy for anyone to update — the mechanism was all there and the front door was missing. So it goes back beside screenshot, aegis and pdf-editor: seeded into every profile by the build, listed under "Built into Theseus", and kept current between releases by the operator-signed channel at theseus.x/extensions/docx-editor/. That is the arrangement docs/ADDON-UPDATES.md describes, and the one the signing script was written for. About 400 KB compressed in the installer, most of it the vendored editor libraries — next to the ~4 MB of pdf.js that pdf-editor already ships, the weight argument for keeping it out didn't survive contact with the numbers. The end-to-end driver goes back to checking that a fresh profile seeds it, which is the property that actually matters now.
