Subject: [PATCH] feat(agent): complete MVP - 5 tools, conversation
 persistence, verification, evals

- Add risk_assessment and tax_estimate tools (5 total)
- Add server-side conversation persistence (Prisma Conversation/Message models)
- Add conversation CRUD endpoints (list, get, delete)
- Add domain-specific verification layer (allocation sum, market prices, hallucination detection)
- Add evaluation framework with 12 test cases (happy path, edge cases, adversarial)
- Update chat UI with conversation sidebar, verification badges, new suggestions
- Add Railway deployment config (Dockerfile.railway, railway.toml, entrypoint)
- Add deployment guide (DEPLOY.md)

+# Claude Code Instructions
+
+## On Session Start
+Always read these three memory files before doing anything else:
+1. `~/.claude/projects/-Users-jpwilson-Documents-Projects-gauntlet-projects-week2-ghostfolio-ghostfolio/memory/MEMORY.md`
+2. `~/.claude/projects/-Users-jpwilson-Documents-Projects-gauntlet-projects-week2-ghostfolio-ghostfolio/memory/progress.md`
+3. `~/.claude/projects/-Users-jpwilson-Documents-Projects-gauntlet-projects-week2-ghostfolio-ghostfolio/memory/architecture.md`
+
+## Git Conventions
+- No Co-Authored-By lines in commits
+- Use --no-verify on commits (pre-existing ESLint bug in repo)
+- Branch: feature/agent-mvp
+- Fork: https://github.com/jpwilson/ghostfolioJPGauntlet
+
+## Dev Environment
+- Node 22 via nvm (`nvm use 22`)
+- Docker for Postgres + Redis: `docker compose -f docker/docker-compose.dev.yml --env-file .env up -d`
+- API server: `npm run start:server` (port 3333)

+# Deploying Ghostfolio Agent to Railway
+
+## Prerequisites
+- Railway account (https://railway.app)
+- Railway CLI installed (`npm install -g @railway/cli`)
+- GitHub repo pushed with latest changes
+
+## Step 1: Create Railway Project
+
+```bash
+railway login
+railway init
+```
+
+## Step 2: Add Services
+
+In the Railway dashboard or via CLI:
+
+1. **PostgreSQL**: Add a PostgreSQL plugin
+2. **Redis**: Add a Redis plugin
+3. **App**: Link to your GitHub repo
+
+## Step 3: Configure Environment Variables
+
+Set these in Railway dashboard for the app service:
+
+```
+# Database (auto-set by Railway Postgres plugin, but verify format)
+DATABASE_URL=${{Postgres.DATABASE_URL}}?connect_timeout=300&sslmode=require
+
+# Redis (auto-set by Railway Redis plugin)
+REDIS_HOST=${{Redis.REDIS_HOST}}
+REDIS_PORT=${{Redis.REDIS_PORT}}
+REDIS_PASSWORD=${{Redis.REDIS_PASSWORD}}
+
+# App secrets (generate random strings)
+ACCESS_TOKEN_SALT=<random-32-char-string>
+JWT_SECRET_KEY=<random-32-char-string>
+
+# AI
+OPENAI_API_KEY=sk-your-openai-key
+
+# Timezone (critical for portfolio calculations)
+TZ=UTC
+
+# Port (Railway provides this)
+PORT=3333
+```
+
+## Step 4: Deploy
+
+Push to GitHub and Railway auto-deploys, or:
+
+```bash
+railway up
+```
+
+## Step 5: Verify
+
+1. Check deployment logs in Railway dashboard
+2. Visit `https://your-app.railway.app/api/v1/health`
+3. Visit `https://your-app.railway.app/api/v1/agent/ui`
+
+## Troubleshooting
+
+- If portfolio shows 0.00: Ensure `TZ=UTC` is set
+- If agent fails: Ensure `OPENAI_API_KEY` is set
+- If DB errors: Check `DATABASE_URL` format includes `?sslmode=require`
