 1. Runs `node --build-sea sea-config.json`, which generates the blob, copies the Node.js binary, and injects the code into it — all internally, using the same [LIEF](https://lief.re/)-based logic that used to live in the external `postject` tool (now folded into Node core and no longer needed as a dependency)
 2. Signs the resulting binary (macOS specific)

+`sea-config.json` also enables `useCodeCache`, which pre-compiles the bundle to V8 bytecode at build time for a faster cold start, and demonstrates `assets`: `assets/greeting.txt` is embedded into the binary at build time and read back at runtime in `hello.ts` via `node:sea`'s `isSea()` / `getAsset()`. It only prints when actually running as a SEA — `npm start` (plain ts-node, not a SEA) skips it. Another option worth knowing about: `useSnapshot` (V8 heap snapshot for even faster startup — not used here, since it requires restructuring the entry point around `v8.startupSnapshot`) and `execArgv` (bake in default CLI flags).

+- The SEA binary is platform-specific; you'll need to build it on each target platform. CI builds and smoke-tests it on Linux, macOS, and Windows on every push/PR (see `.github/workflows/ci.yml`).
 - Source maps are included for debugging, but not used in the final SEA

 ## Future Improvements
 
-Here are some potential enhancements that could be implemented to improve the project:
+Done so far: unit tests (`node:test`), CI with a cross-platform build matrix (GitHub Actions), and linting/formatting (Biome). Still open:
 
-1. **Automated Testing**
-   - Add unit tests for core functionality using Jest or Mocha
-   - Implement integration tests for the SEA build process
-   - Add end-to-end testing for the executable
-   - Set up test coverage reporting
+1. **Testing**
+   - Integration/end-to-end tests for the built binary itself, beyond the CI smoke test
+   - Test coverage reporting
 
-2. **Continuous Integration/Deployment**
-   - Set up GitHub Actions
-   - Implement automated builds for different platforms
-   - Add automated release management
-   - Configure deployment workflows
+2. **Release automation**
+   - Automated release management (tag → build matrix → attach binaries to a GitHub Release)
 
 3. **Code Quality**
-   - Integrate Biome for code formatting and linting
-   - Implement SonarQube for code quality metrics
-   - Set up pre-commit hooks for code quality checks
    - Watch `ts-node` for TypeScript 7 (native Go compiler, GA July 2026) support before upgrading past TS 5.9 — TS 7 shipped without a stable programmatic API, which `ts-node` depends on
+   - Pre-commit hooks (e.g. via Biome's own git hooks support)
 
 4. **Documentation**
    - Add JSDoc documentation for all functions
-   - Generate API documentation
    - Create contribution guidelines
-   - Add architecture diagrams
 
 5. **Performance**
-   - Implement build size optimization
-   - Add performance benchmarking
-   - Optimize startup time
-   - Implement caching strategies
+   - Add performance/startup-time benchmarking
+   - Consider `useSnapshot` for faster cold starts (see `sea-config.json` discussion above)
