Found by building a consumer against a fresh install: an installed libakstdlib was not usable. akstdlibConfig.cmake calls find_dependency(akerror), and the top-level build pulls the submodule in EXCLUDE_FROM_ALL, so `cmake --install` on this project installs only this project and leaves that dependency unresolvable. CI had been hiding it by installing libakerror@main in a separate step -- a different libakerror from the one actually compiled, which is the inconsistency TODO.md 2.3 recorded and the previous commit removed. Removing it exposed the real gap. CI now installs deps/libakerror, the same commit the top-level build compiles, so there is one libakerror in play and the install is consumable. tests/consumer/ is the check that would have caught it: a standalone project, configured against CMAKE_PREFIX_PATH rather than as part of this build, because being part of this build is exactly what would let it pass without testing anything. It exercises what only an install has -- find_package with a version request against the generated version file, find_dependency(akerror) resolving, and the exported akstdlib::akstdlib target -- and touches one function from each of the four sources, so a library installed with a source file missing from its link line fails there rather than in the next consumer to find it.
