-NumLeftoverMovesToSelect(IN SEARCHER_THREAD_CONTEXT *ctx, IN ULONG uDepth)
-/**
-
-Routine description:
-
- How many "leftover" (below GOOD_MOVE -- see search.c's
- TRY_GENERATED_MOVES gate) moves are worth a full SelectBestWithHistory
- scan before we give up and just take the remainder in whatever order
- they're sitting in. Only ever consulted once every high-performer
- move (winning/even capture, killer, killer-mate) has already been
- exhausted -- this never limits how many of *those* get selected,
- only how much further care to spend on the ordinary/leftover tail.
-
- Replaces the old g_uSearchSortLimits[ply], indexed by distance from
- the root -- a poor proxy for what actually matters here, which is
- how large the remaining subtree below this node is (distance from
- root only correlates with that when total search depth is roughly
- fixed; it says nothing once extensions/reductions/iterative-deepening
- are in play). uDepth (remaining depth, in ONE_PLY units, possibly
- fractional) is the more principled signal: a bigger remaining
- subtree makes the cost of a few extra O(n) selection scans more
- worth paying to avoid a bad early choice cascading into extra
- full-width re-searches.
-
- STARTING POINT, NOT YET VALIDATED under this new meaning: this
- reuses the previous table's six numbers verbatim, just reindexed by
- plies of *remaining* depth instead of *distance from root* -- same
- overall shape (more care with more depth left), same specific
- values, carried over only because they're a known, testable
- starting point, not because they were ever confirmed correct here.
