Expected output: COSMOS v8.5+

If you get "command not found", you need to complete COSMOS installation first.

🏗️ Understanding ROXY-SYSTEMS Architecture

ROXY-SYSTEMS is a polyglot microservices platform that demonstrates real-world enterprise patterns:

🎯 Domain-Driven Design

Services are organized by business domain, not technology:

🔄 Two-Tier CI/CD Pipeline

Separate pipelines for infrastructure and applications:

🛡️ Security by Default

Every artifact is scanned and signed:

📥 Step 1: Clone ROXY-SYSTEMS

Navigate to your Code directory:

cd ~/Code

Clone the repository:

git clone https://github.com/vepsservice07-stack/roxy-systems.git

✅ Replace with your actual repository URL!

Enter the directory:

cd roxy-systems

Verify you're in the right place:

ls -la

You should see:

✅ Perfect! You're in the ROXY-SYSTEMS repository.

⚙️ Step 2: Install ROXY-SYSTEMS Environment

ROXY-SYSTEMS has its own installer that integrates with COSMOS.

Run the installer:

./install.sh
🆕 What the ROXY-SYSTEMS Installer Does

The installer extends your COSMOS environment with ROXY-specific features:

What you'll see during installation:

  1. ✅ Checking COSMOS installation...
  2. ✅ Detecting language tools (Rust, Go, Node, Java, Python)...
  3. ✅ Validating cosmos.json manifest...
  4. ✅ Installing git hooks...
  5. ✅ Initializing C-MOS ledger for ROXY-SYSTEMS...
  6. ✅ Configuring cloud integration...
  7. ✅ Setting up issue tracking...
  8. ✅ Installation complete!

🎉 Installation Complete!

You now have:

Verify installation:

c-pulse

You should see: A formatted table showing all ROXY-SYSTEMS services with their current status, versions, and language badges.

Example output:

IDENTITY (PLANE/LANG)                VERSION         STATUS
================================================================================
🦀 [RUST] signer-service             v0.1.0          ⚠ UNRELEASED
🦀 [RUST] identity-service           v0.1.0          ⚠ UNRELEASED
🔹 [GO]   gateway-service            v0.1.0          ⚠ UNRELEASED

☕ [JAVA] system-services-1          v0.1.0          ⚠ UNRELEASED
================================================================================

This shows all services are detected and ready for development!

🗺️ Step 3: Understanding the Repository Structure

ROXY-SYSTEMS follows a specific organization pattern. Let's explore it:

View the full structure:

tree -L 3 -I 'node_modules|target|.git'

Or if tree isn't installed:

find . -maxdepth 3 -type d | grep -v node_modules | grep -v target | grep -v .git

Key directories explained:

📦 src/
Service source code organized by domain
You'll spend most time here
🐳 docker/
Container definitions (base + service)
Infrastructure team manages this
☸️ kubernetes/
Deployment manifests and configs
Platform team manages this
🔧 deployment/
Release and rollback scripts
Used by CI/CD automation
⚙️ .github/workflows/
CI/CD pipeline definitions
Automatically triggered by tags
🧪 tests/
Integration and E2E tests
Run before deployment

🔍 Step 4: Exploring Service Domains

ROXY-SYSTEMS organizes services by business domain. Let's see what's available:

View all services:

cat cosmos.json | jq '.projects[] | {name: .name, path: .path, language: .language, type: .type}'

Service domains breakdown:

🔐 roxy-identity (Authentication & Security)

Services:

Purpose: Handles all authentication, authorization, and cryptographic operations

🌐 roxy-gateway (API Gateway)

Services:

Purpose: Entry point for all client requests, handles routing and rate limiting

⚙️ roxy-processing (Background Processing)

Services:

Purpose: Handles asynchronous operations and batch processing

💻 roxy-interface (User Interfaces)

Services:

Purpose: User-facing web applications

🔧 roxy-system (Infrastructure Services)

Services:

Purpose: Infrastructure support, monitoring, and automation

🎯 Step 5: Pick Your First Issue

Now that you understand the architecture, let's find something to work on.

Option 1: Use c-issue (Recommended)

c-issue list good-first-issue

This shows tasks tagged for new contributors. Pick one that interests you!

Option 2: Browse on GitHub

  1. Go to the repository on GitHub
  2. Click "Issues" tab
  3. Filter by label: good-first-issue
  4. Read through and pick one

Option 3: Create your own improvement

c-issue create

Follow the prompts to create a new issue for something you want to improve.

💡 Good First Issues typically include:

🛠️ Step 6: Make Your Change

Let's say you picked: "Add error handling examples to signer-service README"

Navigate to the service:

cd src/roxy-identity/signer-service

View the current README:

cat README.md

Edit the file:

Use your favorite editor (VS Code, vim, nano, etc.):

code README.md

Or:

nano README.md

Add your improvements

For this example, add an error handling section:

## Error Handling

The signer service returns structured errors:

```rust
pub enum SignerError {
    InvalidKey,
    SignatureFailed,
    VerificationFailed,
}
```

Handle errors appropriately in client code:

```rust
match signer.sign(&data) {
    Ok(signature) => println!("Signed: {}", signature),
    Err(SignerError::InvalidKey) => eprintln!("Invalid key provided"),
    Err(e) => eprintln!("Sign failed: {:?}", e),
}
```

Save the file

In VS Code: Ctrl+S (or Cmd+S on Mac)

In nano: Ctrl+X, then Y, then Enter

✅ Step 7: Validate Your Changes

Before committing, verify nothing broke.

Return to repository root:

cd ~/Code/roxy-systems

Check what changed:

git status

You should see:

modified:   src/roxy-identity/signer-service/README.md

Preview the changes:

git diff src/roxy-identity/signer-service/README.md

Verify your additions look correct.

💡 For Code Changes (not documentation):

💾 Step 8: Commit with COSMOS

Now use the COSMOS workflow to save your changes properly.

Run c-commit:

c-commit --no-verify

Note: We use --no-verify for documentation-only changes to skip code validation.

Answer the prompts:

1. "Selection (default: chore):"
→ Type 4 and press Enter (docs)

2. "Commit message (required):"
→ Type: add error handling examples to signer-service README
→ Press Enter

COSMOS will auto-detect the scope as signer-service and format your message as:

docs(signer-service): add error handling examples to signer-service README
🔍 What Happened Behind the Scenes

COSMOS just performed several critical operations:

Verify the commit:

git log -1 --oneline

You should see your formatted commit message!

🌐 Step 9: Share with the Team

Upload your change to GitHub so the team can see it and CI/CD can validate it.

Push your changes:

git push

What happens next:

  1. Your commit appears on GitHub
  2. C-MOS events sync to cloud storage
  3. Merkle chain is verified
  4. Team members see your contribution
  5. Your name is in the codebase history
🌩️ Cloud Sync in Progress

Your C-MOS events are being synced to your cloud provider:

View your commit online:

  1. Go to the ROXY-SYSTEMS repository on GitHub
  2. Click "Commits" tab
  3. Your commit should appear at the top!

✅ Your first ROXY-SYSTEMS contribution is now live!

🚀 Step 10: Creating a Release (Advanced)

Once your changes are reviewed and approved, you might need to create a release. This is typically done by team leads, but understanding the process is valuable.

⚠️ Release Permission Required

Only create releases after:

Preview the release (safe to run):

c-test src/roxy-identity/signer-service

This shows you what would happen without making any changes:

Execute the release (requires permission):

c-linker src/roxy-identity/signer-service
🔒 What c-linker Does (Production-Grade Release)

The linker runs through a comprehensive 13-phase release process:

  1. Phase -1: Cloud Availability – Verifies cloud is accessible (mandatory)
  2. Phase 0: Tombstone Check – Ensures service wasn't previously deleted
  3. Phase 0.5: C-MOS Verification – Runs all 7 compliance guarantees
  4. Phase 1: Input Validation – Checks service path and structure
  5. Phase 2: Pre-Release Snapshot – Captures current state
  6. Phase 3: Git Validation – Ensures no uncommitted changes
  7. Phase 4: Version Calculation – Determines semantic version bump
  8. Phase 5: Manifest Update – Updates Cargo.toml/package.json/etc.
  9. Phase 6: Changelog Generation – Creates release notes
  10. Phase 7: Release Commit – Creates version bump commit
  11. Phase 8: Release Tag – Creates immutable git tag
  12. Phase 9: Post-Release Snapshot – Captures final state + Merkle verification
  13. Phase 10: Cloud Finalization – Syncs all events to cloud with verification

If any phase fails, the entire release is rolled back.

Push the release tag:

git push --follow-tags

This triggers the CI/CD pipeline automatically!

⚙️ Step 11: Understanding the CI/CD Pipeline

ROXY-SYSTEMS has a sophisticated two-tier pipeline that automatically builds, tests, and deploys your code.

Control Plane (Base Images)

📦 Weekly Base Image Builds

Workflow: .github/workflows/build-base-images.yml

Triggered by:

What it does:

  1. Builds base images for each language (Rust, Go, Node, Java, Python)
  2. Installs language-specific tools and dependencies
  3. Caches layers for faster service builds
  4. Pushes to Artifact Registry
  5. Tags with date and language version

Example images:

Application Plane (Service Builds)

🚀 Service Release Pipeline

Workflow: .github/workflows/build-and-push.yml

Triggered by: Git tags matching *-v*.*.* pattern

Example tag: signer-service-v1.2.3

Complete pipeline flow:

  1. Checkout Code – Gets the tagged version
  2. Extract Metadata – Parses service name and version from tag
  3. Authenticate to Cloud – Uses Workload Identity Federation (no keys!)
  4. Pull Base Image – Uses appropriate language base
  5. Build Service – Runs language-specific build (cargo build, go build, etc.)
  6. Run Tests – Executes unit and integration tests
  7. Build Docker Image – Creates final container
  8. Scan for Vulnerabilities – Trivy scans for CVEs
  9. Sign Image – Cosign creates cryptographic signature
  10. Push to Registry – Uploads to Artifact Registry
  11. Update Kubernetes Manifests – Updates deployment configs
  12. Deploy to Staging – Automatic deployment to staging environment
🔐 Security Features Built-In

👀 Step 12: Watch Your Release Deploy

After pushing your release tag, watch the automation in action!

View the workflow run:

  1. Go to GitHub repository
  2. Click "Actions" tab
  3. Find your service's workflow (should be running)
  4. Click to see detailed logs

What you'll see:

✅ Successful Pipeline

└─ Deploy to staging ✓

✅ Workflow completed successfully in 8m 42s
🎉 Success! Your code is now:

📊 Step 13: Verify C-MOS Compliance

ROXY-SYSTEMS uses the C-MOS system to maintain complete audit trails. Let's verify everything is working.

Check the audit trail:

c-audit

This shows:

Deep dive into your service:

c-audit src/roxy-identity/signer-service

This shows detailed history for that specific service.

Verify C-MOS compliance:

cosmos-cmos-verify verify

This runs all 7 compliance guarantees:

  1. ✅ Global Total Ordering – Events strictly ordered
  2. ✅ 50ms Deterministic Finality – Validation completes in ≤50ms
  3. ✅ Immutable Append-Only Evidence – No deletions allowed
  4. ✅ Deterministic Stateless Validation – Reproducible results
  5. ✅ Recorded Negative Flow – Failures tracked
  6. ✅ Decoupled Read Model – Audit separate from operations
  7. ✅ Auditor-Verifiable Truth – Complete replay capability
✅ All Guarantees Passed

Your repository maintains SOC2-compliant audit trails!

🛡️ Critical Rules for ROXY-SYSTEMS

RULE 1: Always Use COSMOS Tools
RULE 2: Only Edit src/ and tests/
RULE 3: Test Locally Before Committing
RULE 4: Never Force-Push or Rewrite History
RULE 5: Releases Require Approval

❓ Common Scenarios & Solutions

Scenario 1: Fix a Bug in Rust Service

cd src/roxy-identity/signer-service # Fix the bug in src/lib.rs cargo check cargo test cd ~/Code/roxy-systems c-commit # Type: fix # Message: correct signature validation logic git push

Scenario 2: Add Tests to Go Service

cd src/roxy-gateway/gateway-service # Add test file: rate_limiter_test.go go test ./... cd ~/Code/roxy-systems c-commit # Type: test # Message: add comprehensive rate limiter tests git push

Scenario 3: Update Node.js Dependencies

cd src/roxy-interface/webui npm update npm audit fix npm test cd ~/Code/roxy-systems c-commit # Type: chore # Message: update dependencies and fix vulnerabilities git push

Scenario 4: Improve Documentation

cd src/roxy-processing/scheduler # Edit README.md cd ~/Code/roxy-systems c-commit --no-verify # Type: docs # Message: add job scheduling examples git push

Scenario 5: Feature Requiring Review

# Create feature branch git checkout -b feat/new-auth-method # Make changes cd src/roxy-identity/identity-service # ... edit code ... cargo test # Commit (uses COSMOS) cd ~/Code/roxy-systems c-commit git push origin feat/new-auth-method # On GitHub: Create Pull Request # Wait for review and approval # Merge after approval

🆘 Troubleshooting Guide

Problem: "command not found: c-commit"

Solution:

  1. Verify COSMOS is installed: cd ~/Code/cosmos-systems && ./install.sh
  2. Check PATH: echo $PATH | grep /usr/local/bin
  3. Re-source shell: source ~/.bashrc or source ~/.zshrc

Problem: "cargo check failed" or similar validation error

Solution:

This is intentional! COSMOS is preventing broken code from reaching the team.

  1. Read the error message carefully
  2. Fix the code issue
  3. Run validation again locally
  4. Try c-commit again

Problem: "Someone else pushed and I'm behind"

Solution:

git pull --rebase # Fix any conflicts if needed git push

Problem: "I committed by mistake"

Solution (if NOT pushed yet):

git reset HEAD~1 # Your changes are now unstaged # Fix them and commit again

Solution (if already pushed):

Contact your team lead! Never force-push. They'll help you revert safely.

Problem: "CI/CD pipeline failed"

Solution:

  1. Go to GitHub → Actions tab
  2. Click on the failed workflow
  3. Read the error logs
  4. Common causes:
    • Tests failing (fix tests or code)
    • Vulnerability found (update dependencies)
    • Build error (fix syntax/imports)
  5. Fix the issue and push again

Problem: "I need to skip validation for docs-only change"

Solution:

c-commit --no-verify

Use sparingly! Validation exists for good reason.

Problem: "Cloud sync failed"

Solution:

# Verify cloud configuration cosmos-cloud-config-manager verify # Manually sync if needed cosmos-cloud-uploader sync

🏆 Success Stories

Here's what other newcomers accomplished in their first months:

"I deployed my first feature in week 2"

"After going through the onboarding, I picked up a small issue in the gateway service. The COSMOS tools made it impossible to mess up—validation caught my mistakes before they reached the team. By the end of week 2, my code was in staging!"

— Alex, Backend Engineer

"C-MOS saved us during an audit"

"We had a surprise SOC2 audit. Because COSMOS automatically records everything to the C-MOS ledger with cryptographic proof, we had complete evidence of our change management process. What could have been weeks of scrambling took one afternoon to generate reports."

— Jordan, DevOps Lead

"The learning curve is real, but worth it"

"I won't lie—the first week felt overwhelming. So many new concepts! But the documentation is thorough, and the tools prevent you from making mistakes. By week 3, I was helping onboard the next person. By month 2, I was reviewing architecture proposals."

— Sam, Full-Stack Engineer

"Multi-language support is incredible"

"I came from a pure Python background. ROXY-SYSTEMS has Rust, Go, Node, Java, and Python services. COSMOS validates all of them automatically. I didn't need to learn five different build systems—the tools just work. Now I'm comfortable contributing to any service."
