+# Log-Free Codebase Policy
+
+## Overview
+
+The Project Mycelium maintains a **log-free codebase** in main and development branches as a core architectural design decision. This policy ensures clean, production-ready code and simplifies maintenance, debugging, and AI-assisted development.
+
+## Policy Statement
+
+**All `log::` statements must be removed from the codebase before merging to main or development branches.**
+
+## Rationale
+
+### 1. **Code Cleanliness**
+- Removes visual clutter and noise from the codebase
+- Improves code readability and maintainability
+- Reduces file size and complexity
+
+### 2. **Production Readiness**
+- Eliminates potential performance overhead from logging statements
+- Prevents accidental logging of sensitive information
+- Ensures consistent behavior across environments
+
+### 3. **AI-Assisted Development**
+- Simplifies code analysis and pattern recognition for AI tools
+- Reduces token count and complexity for AI code generation
+- Enables more accurate code migrations and refactoring
+
+### 4. **Maintenance Benefits**
+- Reduces merge conflicts from logging changes
+- Eliminates outdated or inconsistent log messages
+- Simplifies code review process
+
+## Implementation Guidelines
+
+### ✅ **Allowed Usage**
+- **Feature Branches**: Developers may use `log::` statements for troubleshooting and debugging in feature branches
+- **Local Development**: Temporary logging for development and testing purposes
+- **Debugging Sessions**: Short-term logging to diagnose specific issues
+
+### ❌ **Prohibited Usage**
+- **Main Branch**: No `log::` statements allowed in main branch
+- **Development Branch**: No `log::` statements allowed in development branch
+- **Production Code**: No logging statements in production-ready code
+- **Permanent Logging**: No long-term or permanent logging infrastructure
+
+## Enforcement
+
+### 1. **Pre-Merge Cleanup**
+All feature branches must have `log::` statements removed before creating pull requests:
+
+```bash
+# Check for log statements before merging
+find src -name "*.rs" -exec grep -l "log::" {} \;
+
+# Remove all log statements (if any found)
+find src -name "*.rs" -exec perl -i -pe 'BEGIN{undef $/;} s/\s*log::[^;]*;//g' {} \;
+
+# Verify removal
+cargo check --lib
+```
+
+### 2. **Automated Checks**
+- CI/CD pipeline should include log statement detection
+- Pre-commit hooks can prevent accidental commits with logging
+- Code review checklist includes log statement verification
+
+### 3. **Migration History**
+- **2025-01-06**: Removed 881+ log statements from entire codebase
+- **Dashboard Controller**: 443 log statements removed
+- **Other Controllers**: 438 log statements removed across 24 files
+
+## Alternative Approaches
+
+### For Debugging
+Instead of permanent logging, use:
+
+1. **Conditional Compilation**:
+   ```rust
+   #[cfg(debug_assertions)]
+   eprintln!("Debug: {}", value);
+   ```
+
+2. **Feature Flags**:
+   ```rust
+   #[cfg(feature = "debug-logging")]
+   log::debug!("Debug information");
+   ```
+
+3. **Test-Only Logging**:
+   ```rust
+   #[cfg(test)]
+   println!("Test debug: {}", value);
+   ```
+
+### For Production Monitoring
+- Use external monitoring tools (Prometheus, Grafana)
+- Implement structured error handling with Result types
+- Use application metrics instead of log statements
+- Implement health check endpoints
+
+## Benefits Realized
+
+### 1. **Codebase Statistics**
+- **Before**: 881+ log statements across 24 files
+- **After**: 0 log statements (100% reduction)
+- **Compilation**: Clean builds with only minor unused variable warnings
+
+### 2. **Development Improvements**
+- Simplified ResponseBuilder migration process
+- Reduced code complexity for AI-assisted refactoring
+- Cleaner code reviews and merge processes
+- Improved code readability and maintainability
+
+### 3. **Performance Benefits**
+- Reduced binary size
+- Eliminated runtime logging overhead
+- Faster compilation times
+- Cleaner production deployments
+
+## Compliance
+
+### Developer Responsibilities
+1. **Remove all `log::` statements** before creating pull requests
+2. **Verify clean builds** after log removal
+3. **Use alternative debugging approaches** for troubleshooting
+4. **Follow the log-free policy** consistently across all contributions
+
+### Code Review Requirements
+1. **Check for log statements** in all code reviews
+2. **Verify compilation** after any log-related changes
+3. **Ensure policy compliance** before approving merges
+4. **Document any exceptions** (if absolutely necessary)
+
+## Exceptions
+
+**No exceptions are currently allowed.** The log-free policy is absolute for main and development branches.
+
+If logging becomes absolutely necessary for specific use cases, it must be:
+1. Approved by the architecture team
+2. Implemented with feature flags
+3. Documented as an architectural decision
+4. Reviewed regularly for removal
