+/* x86_64 process-startup ABI.
+ *
+ * The loader places an elyz_startup block at a known location (e.g. in a
+ * register or on a special stack page).  The exact ABI depends on the
+ * kernel-to-userspace handoff which is not yet implemented.
+ *
+ * Current state: STUB — the process receives argc/argv on the stack as a
+ * fallback, and the initial memory pool comes from a fixed test region.
