 * Deterministic, license-clean fixture for the r2xsql test-suite: a few
 * named functions (one calling another, so xrefs/callers/callees are
 * non-empty) plus a unique string marker, so the tests in this directory
 * have stable, predictable data to assert against. Portable C (no libc
 * beyond stdio/string), built at test time by the tests Makefile.
