CRITICAL: Repository contaminated with 400+ build artifacts violating architecture

[krystophny]

PROBLEM: Repository root directory contains 400+ build artifacts (PNG, PDF, TXT files) that belong in test/output/ or build/ directories.

EVIDENCE:

find . -name "*.png" -o -name "*.pdf" -o -name "*.txt" | grep -v build/ | grep -v doc/ | wc -l
# Returns: 400

ARCHITECTURAL VIOLATION:

• Root directory artifacts: 0 expected (except essential config files)
• Current state: 400+ scattered artifacts
• Clean repository principle violated

IMPACT:

• Repository navigation confused by artifact clutter
• Git operations slowed by unnecessary file tracking
• Development environment polluted
• Architecture compliance failure

SOLUTION:

1. Move ALL test outputs to test/output/ directory
2. Clean ALL PNG/PDF files from root directory
3. Update .gitignore for proper artifact handling
4. Establish CI check to prevent re-accumulation

PRIORITY: CRITICAL - Architecture compliance failure
