"""Verify the test suite retains automatic source discovery.

Top-level test/*.cpp files are globbed at configure time and recorded in
|
|
test_src.txt. Make reconfigures when an individual test/*.cpp is newer than
|
|
that list. This check prevents a regression to a central append-only list,
|
|
Ninja CONFIGURE_DEPENDS glob restacking, or a glob that never re-runs after

a new file is added.
