PanOffice

An AI-native office suite with web collaboration, assembled from two open-source engines plus our own services:

• PanOffice Desktop — the GenOffice document engines (Apache-2.0) running in a Tauri v2 shell (desktop-tauri/, no Electron in the shipping product), for .docx / .xlsx / .pptx / .pdf with block-level AI editing and byte-preserving round-trip saves. desktop/ holds the upstream Electron fork — engine source and behavioral reference.
• PanOffice Web — Collabora Online (MPL-2.0), embedded over WOPI, for browser-based real-time multi-user editing of the same file formats.
• Arch-GPT — in-house account (JWT SSO) and AI capabilities (OpenAI-compatible LLM gateway); no third-party AI accounts.
• PanOffice Server (server/) — the glue we own: a WOPI host (server/wopi-host), and later the file-sync (Drive) service.

See docs/ARCHITECTURE.md for how the pieces fit, docs/TAURI-MIGRATION.md for the Electron→Tauri plan, docs/ARCHGPT.md for the account/AI integration, docs/CODE-BUILD.md for building Collabora Online from source on this machine (done, verified), and docs/ROADMAP.md for milestones.

Repository layout

desktop-tauri/      shipping desktop shell (Tauri v2 + React) — new
desktop/            GenOffice 0.5.1 fork (Electron; engines + reference)
server/wopi-host/   minimal WOPI host bridging Collabora Online to a file store
deploy/             docker-compose for the web-collaboration stack
docs/               architecture, migration plan, Arch-GPT notes, roadmap

Upstream references kept outside this repo (in ~/panspace/):

• genoffice-0.5.1/ — pristine upstream GenOffice export (diff baseline)
• online/ — Collabora Online source, cloned from Gerrit (the GitHub repo is now an issue tracker only; official read-only mirror: CollaboraOnline/online.mirror)

Quick start

Local development boundary

All PanOffice development runs in this WSL checkout. Start the web shell, WOPI host, native XLSX sidecar, local Collabora build, and the local Arch-GPT CLI bridge with:

./tools/start-services.sh
# open http://127.0.0.1:5180

The script creates an ignored .runtime-local/ directory with a new, empty file store. It never reads deploy/data/files, browser recent-file storage, or any directory on 192.168.1.100. The ARM host is a deployment target only: build and test here, then transfer release artifacts only. Never transfer runtime file stores, .versions, lock files, browser profiles/localStorage, or .runtime-local/. Development services run as transient user units: they survive terminal closure, do not auto-start after a WSL reboot, and can be started again with the same command.

Desktop shell (Tauri; Node ≥ 20 + Rust + platform webview deps — see desktop-tauri/README.md):

cd desktop-tauri
npm install
npm run build:ui     # frontend only; `npm run dev` boots the full Tauri app

Engines / reference Electron fork (works today, upstream-complete):

cd desktop
npm install
npm test
npm run dev:docs     # one app; `npm run dev` runs all editors + shell

Web collaboration (Docker):

cd deploy
docker compose up --build
# open http://localhost:3000 — file list, click a file to edit it in Collabora
# (Collabora is on host port 9981; 9980 belongs to a pre-existing container)

Licensing and branding

• desktop/ is Apache-2.0 (upstream GenOffice). "GenOffice" and "Genspark" are trademarks of Mainfunc, Inc. and may not be used for this fork — user-facing branding has been renamed to PanOffice; the remaining de-branding work is tracked in docs/ROADMAP.md (M2).
• Collabora Online is MPL-2.0. We run it as a separate service and do not link it into the desktop code; any local patches to files under online/ must stay MPL-2.0 and be published. "Collabora" branding is likewise reserved — production builds need own branding (ROADMAP M7).
• New code under desktop-tauri/, server/, deploy/, docs/ is Apache-2.0.
