Version history: new document_versions table (migration 0003) holding full-body snapshots that cascade with the doc. Throttled auto-snapshots on save (>=3min apart, max 40/doc, pruned), explicit manual restore points, and a pre_restore safety copy taken before each restore so restoring is itself undoable. Endpoints under /api/docs/:id/versions, all owner-scoped. Empties and bare renames never snapshot. Export: pure-Go Tiptap-JSON -> Markdown / HTML / plain-text / docx (no cgo/pandoc, single-binary intact), CJK-safe with RFC 5987 filenames. docx is a hand-built OOXML zip. PDF is handled client-side via the browser print dialog + an @media print stylesheet so CJK renders with the reader's own fonts. Frontend: ExportMenu (downloads + Print/PDF) and HistoryPanel (snapshot list, preview, restore) wired into the title row; bilingual zh-first to match chrome. Restore remounts the editor via editorEpoch. Stop saving empty docs: blank Untitled drafts now reuse-on-create and self-discard when navigated away from (refs avoid stale closures). Tests: versions_test.go, export_test.go (incl. valid-zip docx). go build/vet/test, tsc, vite build all clean; live end-to-end smoke verified snapshot/throttle/restore/export.

🌸 Petal
A self-hosted, privacy-first writing editor with warm bubbly design, auto-save, and
local-LLM grammar/ESL suggestions. See petal-spec.md for the full
design spec and BUILD_PLAN.md for build progress.
Stack
Go + chi backend · SQLite (modernc, pure Go) · React + Vite + Tiptap + Tailwind v4 frontend ·
local vLLM/Ollama for AI suggestions. Single-binary deployment (frontend embedded via go:embed).
Local development
Two processes during development:
# 1. Backend (serves /api on :8080)
go run ./cmd/server
# 2. Frontend dev server (HMR on :5173, proxies /api → :8080)
cd web && npm install && npm run dev
Open http://localhost:5173 while developing.
Production build (single binary)
cd web && npm run build # emits web/dist (embedded by the Go binary)
cd .. && go build -o petal ./cmd/server
./petal # serves UI + API on :8080
Configuration is via environment variables — copy .env.example to .env.
Status
Early build, multi-session. Auth (Authentik), Copyleaks plagiarism, and Docker/Traefik
deployment are deferred — see BUILD_PLAN.md.
