+## API Access
+
+### Base URL
+
+```
+https://777wolfpack.runfoo.run/api
+```
+
+### Authentication
+
+```bash
+# Login to get JWT token
+curl -X POST https://777wolfpack.runfoo.run/api/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "admin@runfoo.com",

+
+# Get all batches
+curl https://777wolfpack.runfoo.run/api/batches \
+  -H "Authorization: Bearer YOUR_ACCESS_TOKEN"
+```
+

+
+## Security Notes
+
+⚠️ **IMPORTANT**: These are development/demo credentials.
+
+**Before production use**:
+
+1. Change all default passwords
+2. Implement proper password hashing (currently using plaintext in seed)
+3. Enable 2FA for owner accounts
+4. Rotate JWT secrets
+5. Implement password complexity requirements
+
+---
+
+## Troubleshooting
+
+### "Invalid credentials" error
+
+- Verify you're using the exact email: `admin@runfoo.com`
+- Password is case-sensitive: `password123`
+- Check if database has been seeded (see deployment logs)
+
+### "Cannot connect to server"
+
+- Verify backend is healthy: `docker compose ps`
+- Check backend logs: `docker compose logs backend`
+- Verify Traefik routing is working
+
+### Need to re-seed database
+
+```bash
+ssh admin@nexus-vector
+cd /srv/containers/ca-grow-ops-manager
+docker compose exec backend npx prisma db seed
+```
+
+---
+
+## Adding More Users
+
+Currently, user registration is only available through the seed script or direct database access.
+
+**Coming in Sprint 2**: Admin user management UI
+
+**Temporary workaround** (SSH to nexus-vector):
+
+```bash
+docker compose exec backend npx prisma studio
+# Opens Prisma Studio on localhost:5555
+# Add users manually through the UI
+```
+
+---
+
+**Need help?** Check the logs:
+
+```bash
+ssh admin@nexus-vector "cd /srv/containers/ca-grow-ops-manager && docker compose logs -f"
+```

+# Sprint 1: Fix Backend Health Check
+
+**Date**: 2025-12-09  
+**Status**: In Progress  
+**Duration**: 30 minutes  
+**Priority**: 🔴 Critical
+
+---
+
+## 🎯 Objective
+
+Fix the unhealthy backend container by resolving the Docker health check issue.
+
+---
+
+## 🔍 Problem Diagnosis
+
+### Current State
+
+```
+ca-grow-ops-manager-backend-1    Up 41 minutes (unhealthy)
+```
+
+### Root Cause
+
+The health check in `docker-compose.yml` uses `curl`:
+
+```yaml
+healthcheck:
+  test: [ "CMD", "curl", "-f", "http://localhost:3000/api/healthz" ]
+```
+
+However, the backend container (node:20-alpine) **does not have curl installed**.
+
+### Evidence
+
+- Backend logs show server is running: `Server listening at http://0.0.0.0:3000`
+- Backend is successfully serving requests (login, rooms endpoints working)
+- Health check endpoint exists at `/api/healthz`
+
+---
+
+## ✅ Solution
+
+### Option 1: Use wget (already available in alpine)
+
+Change health check to use `wget` instead of `curl`.
+
+### Option 2: Install curl in Dockerfile
+
+Add `curl` to the alpine packages.
+
+**Chosen**: Option 1 (wget) - simpler, no rebuild needed for testing.
+
+---
+
+## 📋 Implementation Steps
+
+1. ✅ Diagnose issue (check logs, verify endpoint exists)
+2. ⏳ Update `docker-compose.yml` health check to use `wget`
+3. ⏳ Commit and push changes
+4. ⏳ Deploy to nexus-vector
+5. ⏳ Verify health check passes
+
+---
+
+## 🧪 Testing
+
+### Manual Test
+
+```bash
+# SSH to nexus-vector
+ssh admin@nexus-vector
+
+# Test wget works in container
+docker exec ca-grow-ops-manager-backend-1 wget -q -O- http://localhost:3000/api/healthz
+
+# Expected output:
+# {"status":"ok","timestamp":"2025-12-09T..."}
+```
+
+### Verify Health
+
+```bash
+docker compose ps
+# All services should show (healthy)
+```
+
+---
+
+## 📊 Success Criteria
+
+- [ ] Backend container shows `(healthy)` status
+- [ ] Health check endpoint returns 200 OK
+- [ ] No errors in backend logs
+- [ ] Application remains accessible at <https://777wolfpack.runfoo.run>

+- `backend/src/server.ts` (line 28-30)
+
+---
+
+## 📝 Notes
+
+- Backend is actually working fine, just the health check command is wrong
+- This is a non-breaking fix (won't affect running services)
+- After fix, Docker will correctly report container health
