 ## ⚠️ Important Implementation Notes
 
+### Core System Requirements
 - **Solver Configurations**: Use minimal parameters (primarily `verbose: false`) for fair comparison
-- **Database Operations**: Must be atomic with proper error handling
-- **Result Validation**: Positive solve times, valid status codes required
+- **Database Operations**: SQLite with comprehensive metadata and version tracking
+- **Result Validation**: Positive solve times, valid status codes, structure analysis
+- **External Libraries**: CVXPY conversion for DIMACS/SDPLIB compatibility
+- **Problem Structure Analysis**: Automatic variable/constraint counting and classification
+- **Version Tracking**: Complete solver backend and Git commit recording
 - **Logging**: Structured with appropriate levels (DEBUG, INFO, WARNING, ERROR)
-- **Problem Formats**: MPS (LP), QPS (QP), Python modules (SOCP/SDP)
+- **Problem Formats**: MPS (LP), QPS (QP), Python (SOCP/SDP), SeDuMi .mat (DIMACS), SDPA .dat-s (SDPLIB)
+
+### 🚨 CRITICAL DEVELOPMENT CONSTRAINTS (DO NOT VIOLATE)
+
+#### Dependencies Management
+- **NEVER create new requirements files**: The project uses a single `requirements.txt` file at the root
+- **DO NOT create requirements/ directory**: All dependencies are managed through the existing `requirements.txt`
+- **DO NOT split requirements**: Never create separate base.txt, python.txt, or other requirement files
+- **Use existing requirements.txt**: All GitHub Actions workflows must reference the single `requirements.txt`
+
+#### CI/CD Philosophy  
+- **CI must fail when problems exist**: Continuous Integration is designed to detect issues, not hide them
+- **DO NOT mask solver installation failures**: If a solver cannot be installed, the CI should fail
+- **NO graceful degradation in CI**: Avoid `|| echo "warning"` patterns that mask real problems
+- **Validate all dependencies**: The purpose of validation workflows is to ensure all required components work
+
+#### File Structure Integrity
+- **Respect existing file organization**: Do not reorganize without explicit user instruction
+- **Generated reports location**: HTML reports are generated in `docs/pages/` directory
+- **Database location**: SQLite database is at `database/results.db`
+- **Configuration location**: YAML configs are in `config/` directory

 ### Adding New Problems
-1. Place files in appropriate `problems/*/type/` directory
-2. Update `problems/problem_registry.yaml`
-3. Validate with `python main.py --validate`
+1. **Internal Problems**: Place in `problems/light_set/type/` directory
