Code Consistency Validator

Validates type consistency across Rust, TypeScript, and PostgreSQL boundaries.

When to Use

• Reviewing code for type mismatches
• Debugging precision loss issues
• Validating API contracts between languages
• Checking BigInt/Number conversions
• Auditing cross-language data flow

Workflow

Step 1: Run Quick Grep

Use provided grep commands to find potential issues.

Step 2: Check Critical Patterns

Look for Number() on wei/balance, parseInt without radix.

Step 3: Generate Report

Report findings using severity levels (CRITICAL/WARNING/INFO).

---

Critical Type Mappings

Rust	TypeScript	PostgreSQL
i64/u64	bigint (not number!)	BIGINT
U256	string	DECIMAL(36,18)
f64	number	DOUBLE PRECISION

🔴 CRITICAL Patterns

Number(response.profit_wei)  // ❌ Precision loss!
parseInt(hexBalance)         // ❌ Missing radix!
JSON.stringify({ amount: BigInt(x) })  // ❌ Fails!

Quick Grep

grep -rn "Number(" --include="*.ts" | grep -E "(wei|balance|amount)"
grep -rn "parseInt(" --include="*.ts" | grep -v ", 10)" | grep -v ", 16)"

Report Format

🔴 CRITICAL (funds at risk) 🟠 WARNING (potential bugs) 🟡 INFO (style) ✅ VALIDATED
