+ * el_val_t return type instead of an implicit int.  Without these, the
+ * ci-base elb (which does not emit extern-fn forward decls for stub-only
+ * functions) produces truncated 32-bit returns on 64-bit Linux → segfault.
+ *
+ * Guarded by EL_SOUL_DEMO_BUILD: soul-demo.c includes this header but
+ * defines its own (different-arity) versions of some of these functions.
+ * Dockerfile.stage compiles soul-demo with -DEL_SOUL_DEMO_BUILD to skip
+ * this block and avoid conflicting-types errors.
