Detailed Description

One executable PT_LOAD segment, already bounds-checked against the image.

Handed to an elf_exec_segment_fn by elf_foreach_exec_segment so a scanner works from validated offsets instead of re-decoding program-header fields. Consumers read bounded segment ranges through priv_emu_elf_read.

Invariant
offset .. offset + filesz lies inside the source.
The segment is PT_LOAD with PF_X set and filesz is non-zero.
