Detailed Description

Inline syscall sequence emitters using the kernel register convention.

Each emitter appends one complete syscall sequence to a program buffer. The calling convention (which registers carry the syscall id and arguments) is defined in syscall_conventions.h. Emitters handle the encoding so that demo programs only express intent, not ABI details.
