Subject: [PATCH] Enhance documentation to reflect the addition of 22+ mutation
 types in Flakestorm, including advanced prompt-level and system/network-level
 attacks. Update README.md, API_SPECIFICATION.md, CONFIGURATION_GUIDE.md,
 USAGE_GUIDE.md, and related files to improve clarity on mutation strategies,
 testing scenarios, and configuration options. Emphasize the importance of
 comprehensive testing for production AI agents and provide detailed
 descriptions for each mutation type.

+## Production-First by Design
+
+Flakestorm is designed for teams already running AI agents in production. Most production agents use cloud LLM APIs (OpenAI, Gemini, Claude, Perplexity, etc.) and face real traffic, real users, and real abuse patterns.
+
+**Why local LLMs exist in the open source version:**
+- Fast experimentation and proofs-of-concept
+- CI-friendly testing without external dependencies
+- Transparent, extensible chaos engine
+
+**Why production chaos should mirror production reality:**
+Production agents run on cloud infrastructure, process real user inputs, and scale dynamically. Chaos testing should reflect this reality—testing against the same infrastructure, scale, and patterns your agents face in production.
+
+The cloud version removes operational friction: no local model setup, no environment configuration, scalable mutation runs, shared dashboards, and team collaboration. Open source proves the value; cloud delivers production-grade chaos engineering.

+- ✅ **Open Source Core**: Full chaos engine available locally for experimentation and CI
 
-## Toward a Zero-Setup Path
+## Open Source vs Cloud
 
- Future improvements include:
+**Open Source (Always Free):**
+- Core chaos engine with all 22+ mutation types (no artificial feature gating)
+- Local execution for fast experimentation
+- CI-friendly usage without external dependencies
+- Full transparency and extensibility
+- Perfect for proofs-of-concept and development workflows
 
-- **Cloud-hosted mutation generation**: No need to install Ollama locally
-- **One-command setup**: Automated installation and configuration
-- **Docker containers**: Pre-configured environments for instant testing
-- **CI/CD integrations**: Native GitHub Actions, GitLab CI, and more
-- **Comprehensive Reporting**: Dashboard and reports with team collaboration.
+**Cloud (In Progress / Waitlist):**
+- Zero-setup chaos testing (no Ollama, no local models)
+- Scalable runs (thousands of mutations)
+- Shared dashboards & reports
+- Team collaboration
+- Scheduled & continuous chaos runs
+- Production-grade reliability workflows
 
-The goal: Test your agent's robustness with a single command, no local dependencies required.
-
-For now, the local execution path gives you full control and privacy. As we build toward zero-setup, you'll always have the option to run everything locally.
