Cross-document FTS5 search (trigram tokenizer for EN + space-free CJK, kept in sync by triggers, back-filled from existing docs). GET /api/search uses the FTS index for queries >=3 runes and a LIKE fallback for 1-2 (so 2-char Chinese words resolve); snippets are built in Go with rune-aware boundaries and sentinel highlights. Tags: user-scoped tags + document_tags join (both cascade), idempotent create/assign, per-tag doc counts. Doc list and search carry each doc's tags (one tagsByDoc query). Frontend: useTags, TagChip/TagPicker/SearchBox, rewritten DocList with chips + filter bar + search. Tablet/touch: responsive sidebar drawer (hamburger + scrim <768px), coarse- pointer tap targets, tap-to-open + outside-pointerdown-close for suggestion cards. Warm LLM-down state: useCheckpoint llmDown flag drives a gentle bilingual StatusBar note (writing still saves locally). Migration 0004 (tags + FTS). Tests: tags lifecycle, search EN/CJK/LIKE/update- reindex. go build/vet/test, tsc, vite all clean; verified live on deployment host.

🌸 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.
Description
Petal is a self-hosted, privacy-first writing editor for an ESL user. It replaces Grammarly with a warm, bubbly web app that combines Tiptap rich text editing, auto-save cloud storage, and periodic AI-powered grammar/ESL suggestions backed by a local vLLM inference endpoint.
