## 3. Cross-Language Quality Matrix

### 3.1 Naming Guard Enforcement

| Language | Linter Coverage | Bash Coverage | Total | Retirement Feasible? |
|----------|----------------|---------------|-------|---------------------|
| **Go** | 60% (forbidigo proposed) | 40% (forbidden words, depth) | 100% | ❌ NO - Hybrid |
| **Python** | 40% (pep8-naming) | 60% (forbidden words, LOC, depth) | 100% | ❌ NO - Hybrid |
| **TypeScript** | 70% (max-lines, naming) | 30% (forbidden patterns) | 100% | ❌ NO - Hybrid |

**Verdict:** Bash guards CANNOT be retired - hybrid approach required

**What CAN Migrate:**
- Identifier length constraints (all languages via linters)
- File naming conventions (TypeScript oxlint, partial others)
- Complexity limits (all languages via linters)

**What MUST Stay in Bash:**
- Forbidden word patterns (v2, V3, new_, old_, temp) - No regex support in linters
- Path depth enforcement (all languages) - Outside linter scope
- File-level LOC limits (Go, Python) - No linter support
- Allowlist management - Requires cross-file analysis

### 3.2 LOC Guard Enforcement

| Language | File LOC in Linter? | Function LOC? | Line Length? | Bash Required? | Violations |
|----------|---------------------|---------------|--------------|----------------|------------|
| **Go** | ❌ NO | ✅ funlen (80) | ✅ lll (120) | ✅ YES | 121 files |
| **Python** | ❌ NO | ⚠️ Complexity | ⚠️ Line length | ✅ YES | Unknown* |
| **TypeScript** | ✅ max-lines (500) | ✅ max-lines-per-fn | ✅ max-len | ⚠️ PARTIAL | 64 files |

*Python LOC data not in static analysis JSON - requires separate scan

**Total Files Over 500 LOC:** 206+ (121 Go + 64 TypeScript + unknown Python)

**Largest Violators:**
1. Go: server_test.go (1509 lines)
2. TypeScript: IntegrationsView.tsx (1739 lines)
3. TypeScript: types.ts (1208 lines, NO allowlist exception)
