web — Disclosure Bureau Next.js app

Next.js 15 + React 19 + Tailwind + Supabase + assistant-ui.

Quick start (local dev)

# 1. Install deps
npm install

# 2. (Optional) Start local Supabase
#    Requires Docker. Skip if pointing at remote Supabase.
npx supabase init        # first time only — creates supabase/ folder
npx supabase start       # spins up Postgres/GoTrue/Storage on :54321

# 3. Configure env
cp .env.local.example .env.local
# Edit .env.local — paste local Supabase keys (printed by `supabase start`)

# 4. Apply migrations
psql postgresql://postgres:postgres@localhost:54322/postgres \
  -f ../infra/supabase/migrations/0001_chat_schema.sql

# 5. Start dev
npm run dev
# http://localhost:3030

Without Supabase

The app degrades gracefully if Supabase env vars are unset:

• Wiki browsing works (read-only from filesystem)
• Auth bar shows "auth: disabled (dev)"
• Chat bubble shows "Auth not configured"

Useful for quick UI work without spinning up Docker.

Production (Coolify on VPS)

See ../infra/coolify/. Stack:

• Coolify orchestrates everything
• Supabase self-hosted: db.disclosure.top, studio.disclosure.top
• Next.js: disclosure.top
• Meilisearch (shared): search.disclosure.top
• Imgproxy (shared): img.disclosure.top
• Caddy: TLS + reverse proxy (built into Coolify)

Tech notes

• No RAG: chat agent reads markdown directly. Wiki-link traversal substitutes for vector search.
• RLS-first: Supabase Row Level Security enforces "user sees only own sessions" at the DB layer.
• Magic-link auth: no passwords. GoTrue handles email delivery.
• Anti-abuse: per-user budget cap (default $5) + daily message quota (default 100) enforced via check_budget RPC before each Claude call.

Cost

Each chat turn costs ~$0.005-0.05 depending on context size (mostly Haiku $1/M input, $5/M output).
