+# --- 10. unit tests (tests/unit/*.c via munit) ----------------------------
+# Harness contract (see .omo/notepads/stupidtools/learnings.md):
+#   - each tests/unit/<name>.c declares its extra link sources on its FIRST
+#     line as:  /* LINK: ../../src/foo.c ../../src/bar.c */
+#     (paths relative to tests/unit/, space-separated)
+#   - the harness adds -I <repo>/thirdparty/munit -I <repo>/src and
+#     thirdparty/munit/munit.c automatically, compiles with
+#     -std=c23 -Wall -Wextra -Wpedantic, and runs each binary.
+#   - a missing LINK line, a compile failure, or a non-zero exit all FAIL.
