"""Random-search Population component — an uncapped keep-all leaderboard.

One module per component (see :mod:`scaffold`). Random search keeps every evaluated candidate so the
uniform-random policy can draw a parent and its context from the *entire* history rather than a
truncated elite — that full pool is what makes the baseline an exploration comparison point instead of
a hill climb.
