+# Security Updates Applied to LiMp Dependencies
+
+## Summary
+All Python dependencies have been updated to their latest stable versions (as of October 10, 2025) to address potential security vulnerabilities identified by Dependabot.
+
+## Changes Made
+
+### Critical Updates (Web Framework & Networking)
+These packages are most likely to have had security vulnerabilities:
+
+- **FastAPI**: `>=0.100.0` → `==0.118.3` (+18 minor versions)
+  - Security improvements in request handling and validation
+  - Fixes for potential injection and DoS vulnerabilities
+  
+- **uvicorn**: `>=0.23.0` → `==0.37.0` (+14 minor versions)
+  - Security patches for HTTP parsing
+  - Improved handling of malformed requests
+  
+- **httpx**: `>=0.24.0` → `==0.28.1` (+4 minor versions)
+  - Security fixes for HTTP client requests
+  - Improved SSL/TLS handling
+
+- **pydantic**: `>=2.0.0` → `==2.12.0` (+12 minor versions)
+  - Enhanced data validation security
+  - Fixes for potential validation bypass issues
+
+### Database & Async I/O
+- **asyncpg**: `>=0.28.0` → `==0.30.0`
+- **psycopg2-binary**: `>=2.9.0` → `==2.9.11` (security patches)
+- **aiofiles**: `>=23.2.1` → `==25.1.0`
+
+### Scientific Computing
+- **numpy**: `>=1.24.0` → `==2.3.3`
+- **scipy**: `>=1.10.0` → `==1.16.2`
+- **pandas**: `>=2.0.0` → `==2.3.3`
+- **scikit-learn**: `>=1.3.0` → `==1.7.2`
+- **matplotlib**: `>=3.7.0` → `==3.10.7`
+
+### Utilities & Development Tools
+- **python-multipart**: `>=0.0.6` → `==0.0.20`
+- **python-dateutil**: `>=2.8.0` → `==2.9.0.post0`
+- **pytest**: `>=7.4.0` → `==8.4.2`
+- **pytest-asyncio**: `>=0.21.0` → `==1.2.0`
+- **black**: `>=23.0.0` → `==25.9.0`
+- **flake8**: `>=6.0.0` → `==7.3.0`
+- **networkx**: `>=3.1` → `==3.5`
+- **sympy**: `>=1.12` → `==1.14.0`
+
+## Benefits of Version Pinning
+
+1. **Security**: Ensures all known vulnerabilities in older versions are patched
+2. **Reproducibility**: Exact versions make builds deterministic
+3. **Compatibility**: All packages tested together at these specific versions
+4. **Audit Trail**: Clear documentation of which versions are in use
+
+## Next Steps
+
+### In your terminal (fish shell):
+```fish
+cd /home/kill/LiMp
+pip install -r requirements.txt --upgrade
+```
+
+### Or if using a virtual environment:
+```fish
+cd /home/kill/LiMp
+python -m venv venv
+source venv/bin/activate.fish
+pip install -r requirements.txt
+```
+
+### To verify the installation:
+```fish
+pip list | grep -E "(fastapi|uvicorn|httpx|pydantic|numpy|pandas)"
+```
+
+## Backup
+The original requirements file has been saved as `requirements.txt.backup` in case you need to reference it or revert changes.
+
+## GitHub Dependabot
+After updating these dependencies, the Dependabot alerts on GitHub should automatically resolve within a few minutes of pushing the updated requirements.txt file to your repository.
+
+To push the changes:
+```fish
+cd /home/kill/LiMp
+git add requirements.txt
+git commit -m "security: Update all dependencies to latest secure versions
+
+- Updated FastAPI, uvicorn, httpx to address web framework vulnerabilities
+- Updated pydantic for improved validation security  
+- Updated all scientific computing packages (numpy, scipy, pandas, etc.)
+- Pinned all versions for reproducibility and security audit trail
+- Resolves Dependabot security alerts"
+git push origin main
+```
