 - **[arch.md](arch.md) — the architecture split.** How CPU-specific code is kept
  behind a build-time `arch` module so the generic kernel never names x86_64,
  leaving room for other systems (e.g. an AArch64 Raspberry Pi) later.
+- **[sysv.md](sysv.md) — the calling convention.** What "the kernel is SysV" means,
+  and why the loader→kernel boundary has to pin it (the RDI-vs-RCX handoff).
 - **[testing.md](testing.md) — testing.** How the kernel is tested by booting it in
  QEMU and asserting on its serial output — reproducibly, and structured so the
  same tests run across architectures.
