ClassicNet
ClassicNet 為 Mac OS（PowerPC，Mac OS 8/9）帶來現代的網路能力：TLS 1.2/1.3、HTTPS、支援多工與流量控制的 HTTP/2，以及 WebSocket。它以可攜式 C 核心為基礎（在開發主機上經過 fuzzing 與 sanitizer 測試），架構於 Open Transport 之上，並由 mbedTLS 提供 TLS。所有功能都在真實的 Mac OS 9.2.2（PowerPC，QEMU 環境）上完整驗證過：以 TLS 1.3 + HTTP/2 完成含憑證驗證的連線並成功取得 200。採用 Apache-2.0 開源授權。

- Retro68 by autc04 — the cross-compiler toolchain that builds the OS 9 / PowerPC binaries (build dependency).
- Apple Open Transport — the classic Mac networking API ClassicNet’s transport layer sits on.
- HPACK static table — derived from RFC 7541, Appendix A; the Huffman/static tables are generated from the authoritative hpack Python package.
