+valgrind --tool=massif --massif-out-file=massif.out \
+    ./target/release/examples/zkproof_bench
+
+# Visualize
+ms_print massif.out

+twiggy top pkg/ruvector_edge_bg.wasm
+```
+
+---
+
+## 🧪 Testing Strategy
+
+### 1. Correctness Tests (Required)
+All existing tests must pass after optimization:
+
+```bash
+cargo test --package ruvector-edge
+cargo test --package ruvector-edge --features wasm
+```
+
+### 2. Performance Regression Tests
+Add to CI/CD pipeline:
+
+```bash
+# Fail if performance regresses by >5%
+cargo bench --bench zkproof_bench -- --test
+```
+
+### 3. WASM Integration Tests
+Test in real browser:
+
+```javascript
+// In browser console
+const prover = new WasmFinancialProver();
+prover.setIncomeTyped(new Uint32Array([650000, 650000, 680000]));
+
+console.time('proof');
+const proof = await prover.proveIncomeAbove(500000);
+console.timeEnd('proof');

+## 🔒 Security Considerations
+
+### Cryptographic Correctness
+⚠️ **Critical:** Optimizations MUST NOT compromise cryptographic security
+
+**Safe optimizations:**
+- ✅ Caching (point decompression)
+- ✅ Parallelization (independent proofs)
+- ✅ Memory reduction (generator party count)
+- ✅ Serialization format changes
+
+**Unsafe changes:**
+- ❌ Modifying proof generation algorithm
+- ❌ Changing cryptographic parameters
+- ❌ Using non-constant-time operations
+- ❌ Weakening verification logic
+
+### Testing Security Properties
+```bash
+# Ensure constant-time operations
+cargo +nightly test --features ct-tests
+
+# Check for timing leaks
+cargo bench --bench zkproof_bench -- --profile-time
+```
