Changes Summary

🔄 Issue #316: Rate-Limit-Aware WebSocket Reconnection with Jitter

Problem: WebSocket reconnection logic lacked jitter and attempt caps, creating a "thundering herd" problem where multiple clients reconnect simultaneously after outages.

Solution Implemented:

• ✅ Jitter Addition: Added randomized variation (±20%) to exponential backoff delays to prevent synchronized reconnection storms
• ✅ Reconnection Cap: Implemented maximum reconnection attempt limit (10 attempts) with "unavailable" status when exceeded
• ✅ Focus-Aware: Reset attempt counters when users return to the tab, treating it as a fresh signal
• ✅ Recovery Path: Allow recovery from unavailable state when tab regains focus
• ✅ Comprehensive Testing: 9 new tests covering jitter distribution, max attempts, and focus behavior

Files Modified:

• src/hooks/useWebSocket.ts - Enhanced with jitter calculation, attempt tracking, and unavailable status
• src/hooks/useWebSocket.test.ts - Expanded test suite with new scenarios

🛡️ Issue #317: Vulnerability Disclosure Policy

Problem: Repository lacked formal vulnerability reporting process, creating no safe channel for security researchers to report issues.

Solution Implemented:

• ✅ SECURITY.md: Created following GitHub's standard format with:
  • Supported versions table
  • Private vulnerability reporting mechanisms (GitHub Security Advisory + email)
  • Response time commitments (3 business days ACK, 7 days investigation)
  • Safe harbor language protecting researchers
  • Realistic scope and out-of-scope definitions
• ✅ Cross-linking: Added security policy reference in README and bug report template
• ✅ Bug Report Redirect: Updated template to direct security issues to private reporting

Files Created/Modified:

• SECURITY.md (new) - Complete vulnerability disclosure policy
• README.md - Added security section with policy link
• .github/ISSUE_TEMPLATE/bug_report.md - Added security warning with redirect

🚀 Issue #318: Production Deployment/CD Pipeline

Problem: Repository lacked automated deployment mechanism, creating manual bottleneck for production releases.

Solution Implemented:

• ✅ Automated Deployment Workflow: Created .github/workflows/deploy.yml that:
  • Triggers only on main branch merges (not every PR)
  • Implements two-stage pipeline: Build → Deploy
  • Properly injects production environment variables via GitHub secrets
  • Integrates with Vercel for seamless deployment
  • Tracks deployment status and creates summary reports
  • Gracefully handles missing credentials with clear messaging
• ✅ Documentation: Added comprehensive deployment setup guide to README including:
  • Required Vercel secrets configuration
  • Production environment variables
  • Deployment process explanation
  • Setup instructions for maintainers

Files Created/Modified:

• .github/workflows/deploy.yml (new) - Complete production deployment pipeline
• README.md - Added deployment section with setup guide

Key Features:

• Artifact caching for efficient builds
• Automatic deployment status tracking
• Summary report in GitHub Actions
• Configurable for multiple deployment targets

👀 Issue #319: PR Preview Deployments for Visual Review

Problem: Reviewers had to locally checkout branches and run dev server to evaluate UI changes, creating friction for contributors.

Solution Implemented:

• ✅ Automatic PR Previews: Created .github/workflows/preview-deploy.yml that:
  • Automatically deploys each PR to staging environment
  • Posts preview URL as PR comment for easy access
  • Updates automatically on new commits
  • Uses non-production (testnet) backend
• ✅ Fork PR Handling: Gracefully manages fork-originated PRs by:
  • Detecting fork status
  • Posting explanatory comment with local setup instructions
  • Preventing credential exposure
• ✅ Error Handling: Clear messaging for:
  • Missing deployment credentials
  • Failed deployments
  • Incomplete configuration
• ✅ Documentation Updates:
  • Updated PULL_REQUEST_TEMPLATE with preview section
  • Added comprehensive guide to README including:
    • Fork PR limitations explanation
    • Staging-specific environment variables
    • Setup instructions

Files Created/Modified:

• .github/workflows/preview-deploy.yml (new) - Complete PR preview pipeline
• .github/PULL_REQUEST_TEMPLATE.md - Added preview deployment section
• README.md - Added PR preview documentation with limitations and setup

Key Features:

• Concurrency group to prevent unnecessary redeploys
• Fork PR security measures (no secret exposure)
• Configurable staging backend
• Graceful credential and error handling

Testing & Verification

WebSocket Tests

• ✅ 9 unit tests all passing
• ✅ Tests cover: jitter distribution, max attempts, backoff reset, focus handling
• ✅ Full coverage of new reconnection behavior

Workflows

• ✅ .github/workflows/deploy.yml - Ready for Vercel integration
• ✅ .github/workflows/preview-deploy.yml - Ready for PR previews
• ✅ Both workflows include error handling and graceful fallbacks

Documentation

• ✅ All new features documented in README
• ✅ Setup instructions for deployment pipelines
• ✅ Clear explanation of PR preview limitations
• ✅ Security policy and vulnerability reporting guide

---

Configuration Required

To activate all features, maintainers should configure these GitHub repository secrets:

For Production Deployment (#318):

VERCEL_TOKEN             - Vercel API token
VERCEL_ORG_ID            - Vercel organization ID
VERCEL_PROJECT_ID        - Vercel project ID
NEXT_PUBLIC_API_URL      - Production backend URL
NEXT_PUBLIC_WS_URL       - Production WebSocket URL
NEXT_PUBLIC_NETWORK      - Production network
NEXT_PUBLIC_SETTLEMENT_CONTRACT        - Production contract ID
NEXT_PUBLIC_SOLVER_REGISTRY_CONTRACT   - Production contract ID

For PR Previews (#319):

Same Vercel credentials as above, plus optional staging-specific variables:

NEXT_PUBLIC_PREVIEW_API_URL              - Staging backend (defaults to testnet)
NEXT_PUBLIC_PREVIEW_WS_URL               - Staging WebSocket
NEXT_PUBLIC_PREVIEW_NETWORK              - Staging network
NEXT_PUBLIC_PREVIEW_SETTLEMENT_CONTRACT  - Staging contract ID
NEXT_PUBLIC_PREVIEW_SOLVER_REGISTRY_CONTRACT - Staging contract ID
