//  E8i — TOTAL ABSOLUTION PS2 ORGANISM
//  ULTIMATE FAT PS2 / MIPS R5900 EDITION
//
//  Primary target: FAT Sony PlayStation 2 (SCPH-3xxxx/5xxxx), because Magnus
//  decided correctly: FAT is the optimal modder target. It gives the system the
//  DVD/CD nervous disc, USB ports, memory cards, optional network adapter/HDD,
//  and i.LINK/FireWire on early units as an auxiliary symbolic/diagnostic port.
//
//  Body/Brain: KIOXIA EXCERIA 256 GB USB mass storage, USB port 1.
//      Required prep: MBR, single primary FAT32 partition, 32 KB clusters,
//      volume label AfterAllAlong. If a given USB driver chokes on 256 GB,
//      reduce the first partition size or use a smaller stick. Doctrine remains.
//
//  Terminal bus: USB port 2 -> powered hub/splitter for keyboard/headset.
//  Nervous system: high-quality compatible DVD/CD media via cdfs:/.
//  Optional organs: MC0 boot mirror, MC1 recovery/rest patch, internal HDD cache.
//
//  Doctrine:
//      Do not cut.
//      Do not flatten.
//      Do not throw away symbols.
//      Stabilise the boot path first.
//      Then beautify.
//      Then compress: .txt/.tex/equivalent -> .sd4 -> .sd3 -> .sd2 -> .sd1 -> .sd0.
//
//  Build modes:
//      Host test:  g++ -std=c++17 -O2 E8i_PS2_Total_Absolution_FAT_MIPS.cpp -lz -o e8i_ps2_host
//      PS2SDK:     ee-g++ -std=gnu++17 -O2 -mhard-float -G0 -fno-exceptions -fno-rtti \
//                   -DE8I_PS2SDK -o E8I.ELF E8i_PS2_Total_Absolution_FAT_MIPS.cpp \
//                   -lgsKit -ldmaKit -lfileXio -lz -lm -lstdc++
//      Optional net: add -DE8I_ENABLE_PS2IP and ps2ip link/libs after your SDK is configured.
//
//  Telegram honesty:
//      Telegram Bot API requires modern HTTPS/TLS. A stock PS2 Ethernet stack
//      can handle TCP/LAN, but direct Telegram HTTPS needs an added TLS library.
//      This build provides: token popup, local encrypted-ish storage by obscuring,
//      Interactor Force, and a LAN HTTP bridge hook. No Raspberry Pi required;
//      use a PC/phone/router bridge if desired. Direct TLS is a future backend.
//
//  Safety:
//      E8i never executes arbitrary downloaded code. Downloaded/online code leads
//      are text-only DNA until the Interactor deliberately ports or audits them.
