Complete production readiness package for 252-day shadow run validation

---

📋 How to Execute (5-Minute Summary)

Step 1: Pre-Flight (15 min)

# Read this first
GATE_3_PREFLIGHT_CHECKLIST.md

# Run scripts to verify infrastructure
.\gate3_test_api.ps1
.\gate3_check_market_data.ps1

Step 2: Prepare Database (5 min)

# Create test model if needed
# Run: GATE_3_SETUP_SCRIPTS.md SQL scripts
# Creates: model, cleans state, verifies schema

Step 3: Execute Shadow Run (30-60 min)

# Follow GATE_3_EXECUTION_GUIDE.md
# POST /api/shadow-runs with model ID + date window
# Monitor via Hangfire dashboard + polling script

Step 4: Validate Results (10 min)

# Read: GATE_3_RESULTS_VALIDATION.md
# Run SQL queries to verify gates (PBO, DSR, Cost2x)
# Decision: Proceed to approval or remediate

Step 5: Approve (5 min)

# Approval queue auto-populated
# Maker-checker approval via POST /api/v1/approval-queue/{id}/approve
# Model ready for activation

Total Time: ~90-120 minutes
