🚀 How to Run PlanGuard Enterprise

Option 1: 1-Click Windows Launcher (Recommended)

Double-click start.bat:

start.bat

This automatically boots the Python 3.12 REST API server on http://127.0.0.1:3000 and opens the Figma-grade interface in your browser.

Option 2: Run via Terminal

cd C:\Users\Devarsh\.gemini\antigravity-ide\scratch\planguard
python run.py

Option 3: Direct Browser Launch

Open frontend/index.html or the root index.html in Chrome or Edge:

file:///C:/Users/Devarsh/.gemini/antigravity-ide/scratch/planguard/frontend/index.html

🔬 Automated Verification Suite

Run the built-in mathematical verification suite:

python backend/test_engine.py

Results:

• [OK] Geometry Check Passed: Detected 24.2" encroachment into turning circle

• [OK] Compliance Check Passed: Initial Score = 44% (Status: NON-COMPLIANT)

• [OK] Remediation Solver Passed: Remediated Score = 98% (Status: PERMIT-READY)

• [OK] Gemini Neural Engine Passed: Synthesized response from planguard-hybrid-brain

• ALL 4 ENGINES VERIFIED 100% OPERATIONAL.

  • Instantly renders the stamped "Municipal Pre-Flight Compliance Verification" certificate ready for city plan examiners.

4. The Close (2:15 - 2:30)

"19,000 architecture firms and 3.7 million commercial contractors in the US alone spend billions on permit delays. PlanGuard turns a 3-month bureaucratic nightmare into an instant, 3-second automated compile step."
