2048EndgameTablebase v13.6.1

Highlights

• Fixed an AI startup/table-selection error when registered tables contain board-sum goals such as sum-894.
• Integrated compatible board-sum tables into the existing AI table-priority rules. Lookup retains the actual sum goal, rejects unsafe large-tile masking, skips completed goals, and avoids single-tile-only cooldown rules.
• Improved search depth handling while a merge goal of 256 or higher is pending. Empty-space depth caps are relaxed to 7 with five empty cells and 6 with six or more, then return to the normal 4/3 caps after completion. Dynamic masking preserves the tiles needed for the merge; existing search time budgets remain unchanged.
• Updated the web AI WASM build to use the same bounded merge-goal policy.

Notes

• AI board-sum table selection applies to compatible standard-board patterns, not variant boards. Existing table and replay file formats are unchanged.
• Merge-goal protection can increase search work on affected positions; it is not a general speedup or a guarantee of stronger play on every board.
