+docker exec wealthysmart-db-dev psql -U wealthy_user -d wealthysmart -c 'SQL;'

 ## Deployment
 
 - Deployed via Gitea Actions (self-hosted runner on VPS)
 - Push to `main` triggers: GitHub → webhook → Gitea mirror sync → Actions workflow → Docker build & deploy
 - Domain: wealth.cescalante.dev
 - Reverse proxy: nginx-proxy + acme-companion (auto TLS)
+
+## Infrastructure
+
+- **Single server**: `ssh old-vps` — runs everything (WealthySmart, n8n, Forgejo, Vaultwarden, nginx-proxy)
+- `ssh production` is **NOT valid** — do not use
+- n8n UI: https://n8n.cescalante.dev — n8n DB queryable via `docker exec portfolio-db-prod psql -U portfolio_user -d n8n`
+
+## n8n Flows
+
+Four automated flows on old-vps feed data into WealthySmart:
+
+1. **BAC Credit Card** — Gmail trigger → POST /transactions/
+2. **Salary Deposits** — Gmail trigger → POST /transactions/
+3. **Municipal Receipts** — Cron trigger → POST /municipal-receipts/upload
+4. **Pension PDFs** (`e88c3UhBeo9WCbcy`) — Gmail trigger (daily midnight) → POST /pensions/upload
