✅ Environment structure - Only new required variable: POSTGRES_PASSWORD must not have default

Backwards Compatibility

✅ 100% backwards compatible

No breaking API changes
Existing clients continue to work
Mobile app compatible
External integrations unaffected

Risk Assessment

Risk Level	Likelihood	Mitigation
Data Loss	Very Low	Full backup before migration
Downtime	Medium	15-30 minute maintenance window
Rollback Needed	Low	Complete rollback procedure provided
Configuration Issues	Medium	Environment validation included

Pre-Migration Preparation

Step 1: Read Documentation

Required Reading:

COMPLETE_UPDATE.md - Full list of changes
REMEDIATION_REPORT.md - Detailed fix documentation
This file - Migration instructions

Estimated Time: 15 minutes

Step 2: Schedule Maintenance Window

Recommended:

Off-peak hours (e.g., 2 AM - 4 AM local time)
Notify users 24 hours in advance
Have rollback plan ready

Maintenance Window Checklist:

[ ] Maintenance notice sent to users
[ ] Backup administrator available
[ ] Rollback procedures reviewed
[ ] Monitoring tools ready (Sentry, logs, etc.)

Step 3: Verify Current System

# Navigate to project directory
cd /path/to/Full\ RunFlow/Web

# Check current version
git log --oneline -1

# Verify services are running
docker-compose ps

# Expected output:
# NAME                 STATUS
# runflow-app          Up
# runflow-db           Up
# runflow-backup       Up

# Check current build status
npm run build

# Note: Build may FAIL if you have C-01 bug (this is expected)

# Check database health
docker-compose exec db pg_isready -U runflow

# Expected: "accepting connections"

Step 4: Create Complete Backup

4a. Backup Database:

# Create backups directory
mkdir -p backups

# Backup database
docker-compose exec db pg_dump -U runflow runflow > backups/pre-migration-$(date +%Y%m%d-%H%M%S).sql

# Verify backup file exists and has content
ls -lh backups/
# Expected: File > 1MB (depending on data)

# Test backup integrity
head -20 backups/pre-migration-*.sql
# Expected: SQL commands visible

4b. Backup Docker Volumes:

# Backup postgres data volume
docker run --rm \
  -v web_postgres_data:/data \
  -v $(pwd)/backups:/backup \
  alpine tar czf /backup/postgres-data-$(date +%Y%m%d-%H%M%S).tar.gz -C /data .

# Verify volume backup
ls -lh backups/*.tar.gz

4c. Backup Configuration Files:

# Backup .env file
cp .env .env.backup-$(date +%Y%m%d-%H%M%S)

# Backup docker-compose.yml (will be modified)
cp docker-compose.yml docker-compose.yml.backup

# Backup other config files
cp Dockerfile Dockerfile.backup
cp docker-compose.dev.yml docker-compose.dev.yml.backup
cp .dockerignore .dockerignore.backup

# List all backups
ls -lh *.backup*

4d. Document Current State:

# Save current container info
docker-compose ps > backups/containers-before.txt
docker-compose exec app npm list > backups/packages-before.txt
docker-compose exec db psql -U runflow -d runflow -c "\dt" > backups/tables-before.txt

# Save environment variables (sanitized)
docker-compose exec app env | grep -v PASSWORD | grep -v SECRET | grep -v KEY > backups/env-before.txt

Step 5: Prepare New Environment Variables

5a. Review Required Variables:

Create a new .env.template file:

# Database (CRITICAL CHANGE - no default allowed)
POSTGRES_PASSWORD=${POSTGRES_PASSWORD:?Must be set}

# These remain the same (verify they exist)
DATABASE_URL=postgresql://runflow:${POSTGRES_PASSWORD}@db:5432/runflow?schema=public
NEXTAUTH_SECRET=<your-existing-value>
NEXTAUTH_URL=<your-existing-value>
ENCRYPTION_KEY=<your-existing-value>
JWT_SECRET=<your-existing-value>

# New optional variables
SENTRY_DSN=<optional>
NEXT_PUBLIC_SENTRY_DSN=<optional>

5b. Verify Current .env:

# Check current .env has all required variables
grep -E "POSTGRES_PASSWORD|DATABASE_URL|NEXTAUTH_SECRET|ENCRYPTION_KEY|JWT_SECRET" .env

# Expected: All 5 variables present

5c. Generate Missing Secrets:

If any secrets are missing or using weak defaults:

# Generate strong POSTGRES_PASSWORD (if needed)
echo "POSTGRES_PASSWORD=$(openssl rand -base64 24)"

# Generate ENCRYPTION_KEY (if needed or weak)
echo "ENCRYPTION_KEY=$(openssl rand -hex 32)"

# Generate JWT_SECRET (if needed or weak)
echo "JWT_SECRET=$(openssl rand -base64 32)"

# Generate NEXTAUTH_SECRET (if needed or weak)
echo "NEXTAUTH_SECRET=$(openssl rand -base64 32)"

⚠️ IMPORTANT: If you change POSTGRES_PASSWORD, you'll need to:

Update it in all places in .env
Update the database after migration

Step 6: Verify Git Status

# Check current branch
git branch

# Check for uncommitted changes
git status

# If you have local changes you want to keep:
git stash save "local-changes-before-migration"

# Pull latest changes
git fetch origin
git log --oneline origin/main -10

# Expected: See recent commits from February 12, 2026

Migration Steps

Phase 1: Stop Services

Estimated Time: 2 minutes

# Stop all services gracefully
docker-compose down

# Verify all containers stopped
docker-compose ps
# Expected: No containers running

# Verify volumes still exist
docker volume ls | grep web_postgres_data
# Expected: Volume present

⏰ DOWNTIME BEGINS HERE

Phase 2: Update Code

Estimated Time: 3 minutes

# Pull latest changes
git pull origin main

# Or if you have a specific commit hash:
git checkout <commit-hash-with-fixes>

# Verify you're on the correct version
git log --oneline -1
# Expected: Commit from February 12, 2026 with remediation changes

# Check which files changed
git diff HEAD~1 --name-only

# Expected to see:
# - src/middleware.ts
# - src/app/api/auth/strava/callback/route.ts
# - docker-compose.yml
# - Dockerfile
# - And many other files from COMPLETE_UPDATE.md

Phase 3: Update Environment Configuration

Estimated Time: 5 minutes

3a. Backup Current .env:

cp .env .env.pre-migration

3b. Update .env File:

Option 1 - Manual Edit:

# Edit .env
nano .env  # or vim, code, etc.

# Critical change: Ensure POSTGRES_PASSWORD is NOT using default
# BEFORE: POSTGRES_PASSWORD=${POSTGRES_PASSWORD:-runflow}
# AFTER: POSTGRES_PASSWORD=<your-strong-password>

# Add new optional variables if desired:
# SENTRY_DSN=<your-sentry-dsn>
# NEXT_PUBLIC_SENTRY_DSN=<your-public-dsn>

Option 2 - Script Update:

# Update POSTGRES_PASSWORD format (if using default)
# This script changes the syntax to require explicit setting
sed -i 's/POSTGRES_PASSWORD:-runflow/POSTGRES_PASSWORD:?Must be set/g' .env

# Or set explicit strong password:
# Read current password
OLD_PASS=$(grep "^POSTGRES_PASSWORD=" .env | cut -d'=' -f2)

# Generate new strong password if current is weak
if [ "$OLD_PASS" = "runflow" ]; then
  NEW_PASS=$(openssl rand -base64 24)
  sed -i "s|^POSTGRES_PASSWORD=.*|POSTGRES_PASSWORD=$NEW_PASS|" .env
  echo "⚠️  POSTGRES_PASSWORD changed from 'runflow' to '$NEW_PASS'"
  echo "⚠️  Save this password securely!"
fi

3c. Verify .env:

# Check all required variables are set
grep -E "^(POSTGRES_PASSWORD|DATABASE_URL|NEXTAUTH_SECRET|ENCRYPTION_KEY|JWT_SECRET)=" .env

# Expected: All 5 variables present with values (not defaults)

# Verify no placeholders remain
grep -E "change-me|example|your-|<.*>" .env

# Expected: No matches (all placeholders replaced)

Phase 4: Update Dependencies

Estimated Time: 5 minutes

# Install/update Node packages
npm ci

# Expected: packages installed from package-lock.json

# Regenerate Prisma client (CRITICAL for C-01 fix)
npx prisma generate

# Expected output:
# ✔ Generated Prisma Client (x.x.x) to ./node_modules/@prisma/client

# Verify Prisma generation
ls -la node_modules/.prisma/client/
# Expected: Generated files present

Phase 5: Verify Build

Estimated Time: 3 minutes

# Build application
npm run build

# Expected output:
# ✓ Compiled successfully
# Route (app)                                Size     First Load JS
# ƒ Middleware                               26.7 kB
# ...

# If build fails:
# 1. Check error messages
# 2. Verify Prisma client generated: npx prisma generate
# 3. Clear cache: rm -rf .next && npm run build
# 4. See troubleshooting section below

✅ CRITICAL CHECKPOINT: Build MUST succeed before proceeding.

Phase 6: Update Docker Configuration

Estimated Time: 2 minutes

6a. Verify docker-compose.yml Changes:

# Show changes in docker-compose.yml
git diff HEAD~1 docker-compose.yml

# Expected changes:
# - POSTGRES_PASSWORD syntax changed
# - migrator command changed to "migrate deploy"
# - Resource limits added
# - Logging configuration added
# - Sentry env vars added

6b. Verify Dockerfile Changes:

# Show changes in Dockerfile
git diff HEAD~1 Dockerfile

# Expected changes:
# - Node version pinned to 20.11.1-alpine3.19
# - postgresql-client removed from runner
# - NODE_OPTIONS removed from runner

6c. Verify Other Config Files:

# Check .dockerignore
git diff HEAD~1 .dockerignore

# Check docker-compose.dev.yml
git diff HEAD~1 docker-compose.dev.yml

Phase 7: Rebuild Docker Images

Estimated Time: 8-12 minutes

# Build new images with no cache (ensures clean build)
docker-compose build --no-cache

# Expected output:
# [+] Building X.Xs (6/6) FINISHED
# => [app deps 1/4] FROM docker.io/library/node:20.11.1-alpine3.19
# ...
# => [app] exporting to image
# => => exporting layers
# => => writing image sha256:...

# This will take 8-12 minutes depending on your system

# Verify new images created
docker images | grep runflow
# Expected: New images with recent timestamp

Phase 8: Start Services

Estimated Time: 2 minutes

# Start services
docker-compose up -d

# Expected output:
# [+] Running 6/6
#  ✔ Network web_runflow-network              Created
#  ✔ Volume "web_postgres_data"               Created
#  ✔ Container runflow-db                     Started

#  ✔ Container runflow-migrator               Started
#  ✔ Container runflow-app                    Started
#  ✔ Container runflow-backup                 Started

# Check container status
docker-compose ps

# Expected: All containers "Up" or "Exited" (migrator, permissions-fixer should exit with code 0)

Phase 9: Monitor Startup

Estimated Time: 2-3 minutes

# Watch application logs
docker-compose logs -f app

# Wait for this message:
# "Ready on http://localhost:3000"

# Alternatively, watch all logs:
docker-compose logs -f

# Look for:
# - migrator: "Migration applied successfully"
# - db: "database system is ready to accept connections"
# - app: "Compiled successfully"
# - app: "Ready on http://localhost:3000"

# Press Ctrl+C to exit log viewing once app is ready

Phase 10: Verify Database Migrations

Estimated Time: 1 minute

# Check migration status
docker-compose exec app npx prisma migrate status

# Expected output:
# Database schema is up to date!
# 
# The following migration(s) have been applied:
# migrations/
#   └─ <timestamp>_<migration_name>/
#       └─ migration.sql

# Verify database tables
docker-compose exec db psql -U runflow -d runflow -c "\dt"

# Expected: All tables present (Activity, User, Lap, Split, etc.)

# Verify indexes exist
docker-compose exec db psql -U runflow -d runflow -c "\di"

# Expected: Multiple indexes including Activity_stravaId_idx, etc.

Phase 11: Initial Health Check

Estimated Time: 1 minute

# Wait for health check to pass
sleep 30

# Check health endpoint
curl http://localhost:3000/api/health

# Expected response:
# {"status":"healthy"}

# If error, wait 30 more seconds and try again
# Health check may take 40-60 seconds on first startup

# Check detailed health (if you have admin token)
curl -H "Authorization: Bearer <admin-token>" http://localhost:3000/api/health | jq

# Expected: Detailed health info with database, memory, etc.

⏰ DOWNTIME ENDS HERE (if health check passed)

Hour 4-24:

# Check every 2 hours:
curl http://localhost:3000/api/health
docker-compose exec db psql -U runflow -d runflow -c "SELECT COUNT(*) FROM \"Activity\";"

# If using Sentry, check dashboard for errors

First Week

Daily Checks:

# Day 1-7: Run daily

# Health check
curl http://localhost:3000/api/health

# Container status
docker-compose ps

# Resource usage
docker stats --no-stream

# Error count
docker-compose logs app --since 24h | grep -i '"level":"error"' | wc -l

# Database growth
docker-compose exec db psql -U runflow -d runflow -c "SELECT pg_size_pretty(pg_database_size('runflow'));"

# Backup verification
ls -lh backups/
# Verify automated backups are running

Weekly Checks:

# Week 1: Run full verification

# 1. Test all critical features
# 2. Review Sentry error reports (if configured)
# 3. Check for security issues
# 4. Verify backups are being created
# 5. Review logs for patterns
# 6. Check performance metrics

Rollback Procedures

When to Rollback

Immediate Rollback Triggers:

Database corruption detected
Application won't start after 10 minutes
Critical security vulnerability discovered
Data loss detected
Build fails repeatedly

Deferred Rollback Triggers:

Performance degradation > 50%
Multiple non-critical bugs
User reports of issues
Monitoring shows anomalies

Emergency Rollback (< 5 minutes)

Use this if critical issues arise immediately after migration:

# Step 1: Stop new services
docker-compose down

# Step 2: Restore previous code
git checkout <previous-commit-hash>
# Or: git reset --hard HEAD~1

# Step 3: Restore .env
cp .env.pre-migration .env

# Step 4: Restore database
docker-compose up -d db
sleep 10
cat backups/pre-migration-*.sql | docker-compose exec -T db psql -U runflow runflow

# Step 5: Rebuild with previous version
docker-compose build
docker-compose up -d

# Step 6: Verify rollback
curl http://localhost:3000/api/health

# Step 7: Document rollback
echo "Rollback completed at $(date)" >> backups/rollback-log.txt

Standard Rollback (10-15 minutes)

Use this for planned rollback with data preservation:

# Step 1: Document current state (for forensics)
docker-compose logs app > backups/logs-before-rollback-$(date +%Y%m%d-%H%M%S).txt
docker-compose exec db pg_dump -U runflow runflow > backups/after-migration-$(date +%Y%m%d-%H%M%S).sql

# Step 2: Stop services
docker-compose down

# Step 3: Restore database from pre-migration backup
docker-compose up -d db
sleep 10
cat backups/pre-migration-*.sql | docker-compose exec -T db psql -U runflow runflow

# Step 4: Verify database restored
docker-compose exec db psql -U runflow -d runflow -c "SELECT COUNT(*) FROM \"User\";"
docker-compose exec db psql -U runflow -d runflow -c "SELECT COUNT(*) FROM \"Activity\";"
# Compare with counts from backups/migration-results-*.txt

# Step 5: Restore code
git log --oneline -10  # Find pre-migration commit
git checkout <pre-migration-commit>

# Step 6: Restore configuration
cp docker-compose.yml.backup docker-compose.yml
cp Dockerfile.backup Dockerfile
cp .env.pre-migration .env

# Step 7: Restore dependencies
npm ci
npx prisma generate

# Step 8: Rebuild
npm run build
docker-compose build

# Step 9: Start services
docker-compose up -d

# Step 10: Verify rollback
sleep 30
curl http://localhost:3000/api/health
docker-compose logs app | tail -20

# Step 11: Full verification
npm test
curl -H "Authorization: Bearer <token>" http://localhost:3000/api/activities

# Step 12: Document rollback
cat > backups/rollback-report-$(date +%Y%m%d-%H%M%S).txt << EOF
Rollback Date: $(date)
Reason: <reason-for-rollback>
Issues Encountered: <issues>
Data Restored: From backup $(ls -t backups/pre-migration-*.sql | head -1)
Rollback Status: SUCCESS
Verification: PASSED
EOF

Partial Rollback (Specific Files)

Use this if only specific changes need reverting:

# Example: Rollback only middleware changes

# Step 1: Identify problematic files
# From COMPLETE_UPDATE.md, critical files were:
# - src/middleware.ts
# - src/app/api/auth/strava/callback/route.ts
# - docker-compose.yml

# Step 2: Revert specific files
git checkout <previous-commit> -- src/middleware.ts

# Step 3: Rebuild
npm run build

# Step 4: Restart app
docker-compose restart app

# Step 5: Verify
curl http://localhost:3000/api/health

# Example: Rollback docker-compose.yml only
git checkout <previous-commit> -- docker-compose.yml
docker-compose down
docker-compose up -d

error TS2345: Argument of type 'Error' is not assignable to parameter

Cause: Prisma client not regenerated (C-01 fix incomplete)

Solution:

# Clean and regenerate
rm -rf node_modules/.prisma
rm -rf .next
npx prisma generate
npm run build

Issue: "POSTGRES_PASSWORD must be set"

Symptoms:

Error: POSTGRES_PASSWORD must be set

Cause: Environment variable not configured in .env

Solution:

# Generate strong password
PASSWORD=$(openssl rand -base64 24)

# Add to .env
echo "POSTGRES_PASSWORD=$PASSWORD" >> .env

# Update all references
sed -i "s|\${POSTGRES_PASSWORD:?.*}|\${POSTGRES_PASSWORD}|g" .env

# Restart
docker-compose up -d

Issue: Container Restart Loop

Symptoms:

runflow-app restarting

Cause: Health check failing (likely database connection)

Solution:

# Check app logs
docker-compose logs app | tail -50

# Check database status
docker-compose exec db pg_isready -U runflow

# Verify DATABASE_URL
docker-compose exec app env | grep DATABASE_URL

# Common issues:
# 1. Database not ready - wait 30s and check again
# 2. Wrong DATABASE_URL - verify in .env
# 3. Database password mismatch - check POSTGRES_PASSWORD in .env

# Restart in order
docker-compose restart db
sleep 15
docker-compose restart app

Issue: "Migration not found"

Symptoms:

Error: Migration <name> not found

Cause: Migration history mismatch

Solution:

# Check migration status
docker-compose exec app npx prisma migrate status

# If migrations out of sync:
# Option 1: Mark as applied (if migration already in DB)
docker-compose exec app npx prisma migrate resolve --applied <migration-name>

# Option 2: Deploy missing migrations
docker-compose exec app npx prisma migrate deploy

# Verify
docker-compose exec app npx prisma migrate status

Issue: Rate Limiting Too Aggressive

Symptoms:

429 Too Many Requests on normal usage

Cause: Rate limit thresholds too low or identifier collision

Solution:

# Temporary: Restart app to clear in-memory rate limits
docker-compose restart app

# Permanent: Adjust rate limits in code
# Edit src/app/api/auth/verify-email/route.ts
# Change: checkRateLimitAsync(..., 10, 3600)
# To: checkRateLimitAsync(..., 20, 3600)

# Rebuild and restart
npm run build
docker-compose restart app

Issue: XSS Test Failing

Symptoms:

XSS payload not escaped in Strava callback

Cause: C-04 fix not applied correctly

Solution:

# Verify file has fix
grep "safeDeepLinkForHtml" src/app/api/auth/strava/callback/route.ts

# If not present:
git checkout origin/main -- src/app/api/auth/strava/callback/route.ts

# Rebuild
npm run build
docker-compose restart app

# Test
curl "http://localhost:3000/api/auth/strava/callback?code=test&deep_link=<script>alert(1)</script>"
# Expected: &lt;script&gt; (escaped)

Issue: Sentry Not Receiving Errors

Symptoms:

No errors appearing in Sentry dashboard

Cause: Environment variables not set

Solution:

# Check env vars
docker-compose exec app env | grep SENTRY_DSN

# If not set, add to .env:
echo "SENTRY_DSN=<your-sentry-dsn>" >> .env
echo "NEXT_PUBLIC_SENTRY_DSN=<your-public-dsn>" >> .env

# Restart
docker-compose restart app

# Test
curl -X POST http://localhost:3000/api/test-error
# Check Sentry dashboard

Issue: High Memory Usage

Symptoms:

Container using > 2GB memory

Cause: Memory leak or resource limits not applied

Solution:

# Verify limits applied
docker inspect $(docker-compose ps -q app) | jq '.[0].HostConfig.Memory'

# If not set (shows 0):
# Ensure docker-compose.yml has deploy.resources.limits
grep -A 3 "deploy:" docker-compose.yml

# Restart with limits
docker-compose down
docker-compose up -d

# Monitor
docker stats

# If still high:
# 1. Check for memory leaks in logs
# 2. Restart app periodically
# 3. Consider increasing limit to 3-4GB

Issue: Database Connection Pool Exhausted

Symptoms:

Error: Connection pool timeout

Cause: Too many concurrent connections

Solution:

# Check current connections
docker-compose exec db psql -U runflow -d runflow -c "SELECT COUNT(*) FROM pg_stat_activity WHERE datname='runflow';"

# Check max connections
docker-compose exec db psql -U runflow -d runflow -c "SHOW max_connections;"

# If at limit:
# Option 1: Increase Prisma pool size
# Edit prisma/schema.prisma:
# datasource db {
#   url = env("DATABASE_URL")
#   connection_limit = 10  // Add this
# }

# Option 2: Increase PostgreSQL max_connections
# Edit docker-compose.yml:
# db:
#   command: postgres -c max_connections=200

# Restart
npx prisma generate
docker-compose down
docker-compose up -d
