  - `process_transaction_event_1` in `core/processor.py:60` (Complexity: 13, 65 lines)
  - `process_transaction_event_2` in `core/processor.py:80` (Complexity: 14, 65 lines)
  - `process_transaction_event_3` in `core/processor.py:100` (Complexity: 15, 65 lines)
  - `process_transaction_event_4` in `core/processor.py:120` (Complexity: 16, 65 lines)

### 🧪 Pillar 2: Test Density & Verification Health (20.0 / 20.0 pts)
- **Status**: Elite (>35% Test Density)

- **Severity Breakdown**: 0 Critical | 0 High | 1 Medium
  - **[MEDIUM]** permissive_cors in `pkg/gateway/cors.go:42`: Wildcard CORS origin enabled on development router
  - **[LOW]** unpinned_digest in `Dockerfile:1`: Container base image uses floating tag instead of SHA256 digest

### 📦 Pillar 4: Dependency & Licensing Compliance (15.0 / 15.0 pts)
- **Status**: Clean & Permissive
- **Direct Dependencies**: 48 packages
- **Copyleft / Commercial Risk**: 0 packages detected

### 📝 Pillar 5 & 6: Maintainability & Git Hygiene (19.0 / 20.0 pts)
- **Docstring & Comment Density**: 16.0%
- **Maintainability Tier**: High (>12% Doc Density)
- **Continuous Integration Posture**: Standardized branch rules and automated pull request validations verified.

## 3. Technical Debt Quantification & Financial Arbitrage

| Financial Metric | US In-House Benchmark ($165/hr) | LATAM Nearshore Squad ($55/hr) | Net Capital Arbitrage Savings |
| :--- | :--- | :--- | :--- |
| **Total Estimated Debt** | 70 hours | 70 hours | — |
| **Total Remediation Cost** | **$11,515.00** | **$3,850.00** | **$7,665.00 (66.6%)** |

### 🚀 Recommended Nearshore Squad Remediation Plan
- **Dedicated Pod**: 1x Senior Full-Stack / Platform Engineer
- **Delivery Velocity**: 35 refactoring hrs/wk
- **Estimated Remediation Timeline**: 2.0 weeks
- **Total Fixed-Cap Investment**: $3,850.00
- **Guaranteed Outcome**: Refactor high-complexity modules, eliminate 100% of security/secret flags, bring test density above 30%, and elevate RQI to **90+ (A+ Elite)**.
