Run locally

1. Install dependencies with bun install.
2. Copy .env.example to .env.local.
3. Set VITE_SUPABASE_URL and VITE_SUPABASE_ANON_KEY in .env.local.
4. Start the development server with bun run dev.

Open http://localhost:5173/. Public landing pages work without Supabase credentials. Authentication and account data require a configured Supabase project.

For the connected Supabase project, http://localhost:5173/ is an allowed local authentication origin. Registration emails return to the app's current origin. Keep .env.local out of Git, and never expose a service-role key through a VITE_ variable.

Supabase project notes

The connected project is juyzcctqoxypkrcdqahg (Second Brain). The corrective migration 20261017135243_complete_productora_supabase_setup.sql was applied through the dashboard SQL Editor on 2026-10-17. It updates 24 analytics views to use caller RLS, secures profile creation, and backfills missing profiles. The script can be reapplied, but the dashboard does not record CLI migration history. Reconcile the remote history before running db push; the original repository migration is not a complete baseline of the existing database.

The project has four AI edge functions: ai-tags, ai-short-term, ai-long-term, and ai-mermaid. AI generation requires a signed-in session and a valid server-side GEMINI_API_KEY. It was not invoked during setup.
