## 🚨 Issues

- 🔥 Complex funcs: syscalls.js:551:dispatch(215L), cpu.js:451:handle0F(172L), cpu.js:624:step(170L)
- 📁 Large files: src/cpu.js:803L, src/syscalls.js:766L
- 📋 39 duplicated groups
- 🔐 eval() in syscalls.js:458, syscalls.js:607

## 🧹 Dead Code & Tests

**Orphaned:** fetch-alpine-rootfs.mjs, browser_bridge.js, parity.mjs, run-alpine-smoke.mjs, openx86-sw.js, basic.mjs (+21)
**Unused exports:** node.js: NodeTcpNetwork, saveVfsSnapshotToFile
**Tests:** 0/64 (0%)
