+      when reasoning:
+
+      1. In <think>, explain the constraint logic behind the move, not just the final
+      placement. Mention which row, column, or 2x2 box makes the move safe or forced.
+
+      2. Treat each move as a constraint-preserving placement: place a number only
+      if it does not already appear in the same row, column, or 2x2 box.
+
+      3. First look for highly forced cells. If an empty cell has only one legal candidate
+      after checking its row, column, and box, fill it immediately and explain why
+      other numbers are excluded.
+
+      4. If no cell is obviously forced, scan each row, column, and 2x2 box for missing
+      numbers. If a missing number can go in only one empty position within that unit,
+      place it there and state that unit-level reason.
+
+      5. Prefer moves that reduce uncertainty and create new forced cells for the
+      next turn. A good move should make the remaining puzzle more constrained, not
+      more ambiguous.
+
+      6. Solve incrementally: choose exactly one placement, explain it briefly in
+      <think>, then output that one move in <answer>.
+
+      7. Never modify bracketed initial cells or already-filled cells. Only place
+      numbers into dots.
+
+      8. Avoid exploratory guesses when a forced move exists. In this environment,
+      reliable progress usually comes from constraint propagation rather than trial-and-error.
+
+      9. If a previous move was invalid or the board did not change, do not repeat
+      the same placement. Recompute legal candidates and explain the corrected constraint-consistent
+      choice.
+
+      10. Use row, column, and box agreement as confidence: the strongest placements
+      are those supported by multiple constraints at once.
+
+      11. Keep <think> concise but meaningful: identify the target cell, list or compare
+      its legal candidates, and give the decisive constraint.

+      12. Output only the required XML-like format and choose valid Sudoku placements.

+      \ when reasoning:\n1. First compare the box position with the target position;\
+      \ the useful push directions are usually the directions that reduce their row/column\
+      \ distance.\n2. Before pushing, move the player to the square opposite the intended\
+      \ push direction. A move that only repositions the player can be useful if it\
+      \ sets up the next push.\n3. Never push a box into a wall, corner, or narrow\
+      \ dead end unless that square is the target or clearly on the only path to the\
+      \ target.\n4. Prefer short plans that move the single box steadily toward the\
+      \ target; avoid wandering moves that do not improve player position or box position.\n\
+      5. If the box and target are aligned in the same row or column, try to keep\
+      \ the box on that line and push along it.\n6. If they are not aligned, first\
+      \ push to fix one coordinate, then reposition and push to fix the other coordinate.\n\
+      7. Check that after each push, the player can still reach the next required\
+      \ pushing side of the box.\n8. Output only the required XML-like format and\
+      \ choose valid Sokoban actions.\n\nYou are the player and you need to push all\
+      \ boxes to targets. \nWhen you are right next to a box, you can push it by moving\

+      \ when reasoning:\n1. First compare the box position with the target position;\
+      \ the useful push directions are usually the directions that reduce their row/column\
+      \ distance.\n2. Before pushing, move the player to the square opposite the intended\
+      \ push direction. A move that only repositions the player can be useful if it\
+      \ sets up the next push.\n3. Never push a box into a wall, corner, or narrow\
+      \ dead end unless that square is the target or clearly on the only path to the\
+      \ target.\n4. Prefer short plans that move the single box steadily toward the\
+      \ target; avoid wandering moves that do not improve player position or box position.\n\
+      5. If the box and target are aligned in the same row or column, try to keep\
+      \ the box on that line and push along it.\n6. If they are not aligned, first\
+      \ push to fix one coordinate, then reposition and push to fix the other coordinate.\n\
+      7. Check that after each push, the player can still reach the next required\
+      \ pushing side of the box.\n8. Output only the required XML-like format and\
+      \ choose valid Sokoban actions.\n\nYou are the player and you need to push all\

+      \ when reasoning:\n1. First compare the box position with the target position;\
+      \ the useful push directions are usually the directions that reduce their row/column\
+      \ distance.\n2. Before pushing, move the player to the square opposite the intended\
+      \ push direction. A move that only repositions the player can be useful if it\
+      \ sets up the next push.\n3. Never push a box into a wall, corner, or narrow\
+      \ dead end unless that square is the target or clearly on the only path to the\
+      \ target.\n4. Prefer short plans that move the single box steadily toward the\
+      \ target; avoid wandering moves that do not improve player position or box position.\n\
+      5. If the box and target are aligned in the same row or column, try to keep\
+      \ the box on that line and push along it.\n6. If they are not aligned, first\
+      \ push to fix one coordinate, then reposition and push to fix the other coordinate.\n\
+      7. Check that after each push, the player can still reach the next required\
+      \ pushing side of the box.\n8. Output only the required XML-like format and\
+      \ choose valid Sokoban actions.\n\nYou are the player and you need to push all\

+      \ the useful push directions are usually the directions that reduce their row/column\

+      \ push direction. A move that only repositions the player can be useful if it\
+      \ sets up the next push.\n3. Never push a box into a wall, corner, or narrow\
+      \ dead end unless that square is the target or clearly on the only path to the\
+      \ target.\n4. Prefer short plans that move the single box steadily toward the\
+      \ target; avoid wandering moves that do not improve player position or box position.\n\
+      5. If the box and target are aligned in the same row or column, try to keep\
+      \ the box on that line and push along it.\n6. If they are not aligned, first\
+      \ push to fix one coordinate, then reposition and push to fix the other coordinate.\n\
+      7. Check that after each push, the player can still reach the next required\
+      \ pushing side of the box.\n8. Output only the required XML-like format and\

+      \ when reasoning:\n1. First compare the box position with the target position;\
+      \ the useful push directions are usually the directions that reduce their row/column\
+      \ distance.\n2. Before pushing, move the player to the square opposite the intended\
+      \ push direction. A move that only repositions the player can be useful if it\
+      \ sets up the next push.\n3. Never push a box into a wall, corner, or narrow\
+      \ dead end unless that square is the target or clearly on the only path to the\
+      \ target.\n4. Prefer short plans that move the single box steadily toward the\
+      \ target; avoid wandering moves that do not improve player position or box position.\n\
+      5. If the box and target are aligned in the same row or column, try to keep\
+      \ the box on that line and push along it.\n6. If they are not aligned, first\
+      \ push to fix one coordinate, then reposition and push to fix the other coordinate.\n\
+      7. Check that after each push, the player can still reach the next required\
+      \ pushing side of the box.\n8. Output only the required XML-like format and\
+      \ choose valid Sokoban actions.\n\nYou are the player and you need to push all\
+      \ boxes to targets. \nWhen you are right next to a box, you can push it by moving\
+      \ in the same direction. \nYou cannot push a box through a wall, and you cannot\

+      \ when reasoning:\n1. First compare the box position with the target position;\
+      \ the useful push directions are usually the directions that reduce their row/column\
+      \ distance.\n2. Before pushing, move the player to the square opposite the intended\
+      \ push direction. A move that only repositions the player can be useful if it\
+      \ sets up the next push.\n3. Never push a box into a wall, corner, or narrow\
+      \ dead end unless that square is the target or clearly on the only path to the\
+      \ target.\n4. Prefer short plans that move the single box steadily toward the\
+      \ target; avoid wandering moves that do not improve player position or box position.\n\
+      5. If the box and target are aligned in the same row or column, try to keep\
+      \ the box on that line and push along it.\n6. If they are not aligned, first\
+      \ push to fix one coordinate, then reposition and push to fix the other coordinate.\n\
+      7. Check that after each push, the player can still reach the next required\
+      \ pushing side of the box.\n8. Output only the required XML-like format and\
+      \ choose valid Sokoban actions.\n\nYou are the player and you need to push all\
+      \ boxes to targets. \nWhen you are right next to a box, you can push it by moving\
+      \ in the same direction. \nYou cannot push a box through a wall, and you cannot\

+      \ the useful push directions are usually the directions that reduce their row/column\
+      \ distance.\n2. Before pushing, move the player to the square opposite the intended\
+      \ push direction. A move that only repositions the player can be useful if it\
+      \ sets up the next push.\n3. Never push a box into a wall, corner, or narrow\
+      \ dead end unless that square is the target or clearly on the only path to the\
+      \ target.\n4. Prefer short plans that move the single box steadily toward the\
+      \ target; avoid wandering moves that do not improve player position or box position.\n\
+      5. If the box and target are aligned in the same row or column, try to keep\
+      \ the box on that line and push along it.\n6. If they are not aligned, first\
+      \ push to fix one coordinate, then reposition and push to fix the other coordinate.\n\
+      7. Check that after each push, the player can still reach the next required\
+      \ pushing side of the box.\n8. Output only the required XML-like format and\
+      \ choose valid Sokoban actions.\n\nYou are the player and you need to push all\
+      \ boxes to targets. \nWhen you are right next to a box, you can push it by moving\

+      \ push direction. A move that only repositions the player can be useful if it\

+      \ dead end unless that square is the target or clearly on the only path to the\
+      \ target.\n4. Prefer short plans that move the single box steadily toward the\
+      \ target; avoid wandering moves that do not improve player position or box position.\n\
+      5. If the box and target are aligned in the same row or column, try to keep\
+      \ the box on that line and push along it.\n6. If they are not aligned, first\
+      \ push to fix one coordinate, then reposition and push to fix the other coordinate.\n\

+      \ push direction. A move that only repositions the player can be useful if it\

+      \ dead end unless that square is the target or clearly on the only path to the\
+      \ target.\n4. Prefer short plans that move the single box steadily toward the\
+      \ target; avoid wandering moves that do not improve player position or box position.\n\
+      5. If the box and target are aligned in the same row or column, try to keep\
+      \ the box on that line and push along it.\n6. If they are not aligned, first\
+      \ push to fix one coordinate, then reposition and push to fix the other coordinate.\n\

+      \ when reasoning:\n1. First compare the box position with the target position;\
+      \ the useful push directions are usually the directions that reduce their row/column\
+      \ distance.\n2. Before pushing, move the player to the square opposite the intended\
+      \ push direction. A move that only repositions the player can be useful if it\
+      \ sets up the next push.\n3. Never push a box into a wall, corner, or narrow\
+      \ dead end unless that square is the target or clearly on the only path to the\
+      \ target.\n4. Prefer short plans that move the single box steadily toward the\
+      \ target; avoid wandering moves that do not improve player position or box position.\n\
+      5. If the box and target are aligned in the same row or column, try to keep\
+      \ the box on that line and push along it.\n6. If they are not aligned, first\
+      \ push to fix one coordinate, then reposition and push to fix the other coordinate.\n\
+      7. Check that after each push, the player can still reach the next required\
+      \ pushing side of the box.\n8. Output only the required XML-like format and\
+      \ choose valid Sokoban actions.\n\nYou are the player and you need to push all\
+      \ boxes to targets. \nWhen you are right next to a box, you can push it by moving\
+      \ in the same direction. \nYou cannot push a box through a wall, and you cannot\

+      \ the useful push directions are usually the directions that reduce their row/column\

+      \ push direction. A move that only repositions the player can be useful if it\
+      \ sets up the next push.\n3. Never push a box into a wall, corner, or narrow\
+      \ dead end unless that square is the target or clearly on the only path to the\
+      \ target.\n4. Prefer short plans that move the single box steadily toward the\
+      \ target; avoid wandering moves that do not improve player position or box position.\n\
+      5. If the box and target are aligned in the same row or column, try to keep\
+      \ the box on that line and push along it.\n6. If they are not aligned, first\
+      \ push to fix one coordinate, then reposition and push to fix the other coordinate.\n\
+      7. Check that after each push, the player can still reach the next required\
+      \ pushing side of the box.\n8. Output only the required XML-like format and\

+      \ the useful push directions are usually the directions that reduce their row/column\
+      \ distance.\n2. Before pushing, move the player to the square opposite the intended\
+      \ push direction. A move that only repositions the player can be useful if it\
+      \ sets up the next push.\n3. Never push a box into a wall, corner, or narrow\
+      \ dead end unless that square is the target or clearly on the only path to the\
+      \ target.\n4. Prefer short plans that move the single box steadily toward the\
+      \ target; avoid wandering moves that do not improve player position or box position.\n\
+      5. If the box and target are aligned in the same row or column, try to keep\
+      \ the box on that line and push along it.\n6. If they are not aligned, first\
+      \ push to fix one coordinate, then reposition and push to fix the other coordinate.\n\
+      7. Check that after each push, the player can still reach the next required\
+      \ pushing side of the box.\n8. Output only the required XML-like format and\
+      \ choose valid Sokoban actions.\n\nYou are the player and you need to push all\

+      \ push direction. A move that only repositions the player can be useful if it\

+      \ dead end unless that square is the target or clearly on the only path to the\
+      \ target.\n4. Prefer short plans that move the single box steadily toward the\
+      \ target; avoid wandering moves that do not improve player position or box position.\n\
+      5. If the box and target are aligned in the same row or column, try to keep\
+      \ the box on that line and push along it.\n6. If they are not aligned, first\
+      \ push to fix one coordinate, then reposition and push to fix the other coordinate.\n\

+      \ push direction. A move that only repositions the player can be useful if it\

+      \ dead end unless that square is the target or clearly on the only path to the\
+      \ target.\n4. Prefer short plans that move the single box steadily toward the\
+      \ target; avoid wandering moves that do not improve player position or box position.\n\
+      5. If the box and target are aligned in the same row or column, try to keep\
+      \ the box on that line and push along it.\n6. If they are not aligned, first\
+      \ push to fix one coordinate, then reposition and push to fix the other coordinate.\n\
+      7. Check that after each push, the player can still reach the next required\

+    env_instruction: 'You are a careful 4x4 Sudoku solver. Use these reusable abstractions
+      when reasoning:
+
+      1. In <think>, explain the constraint logic behind the move, not just the final
+      placement. Mention which row, column, or 2x2 box makes the move safe or forced.
+
+      2. Treat each move as a constraint-preserving placement: place a number only
+      if it does not already appear in the same row, column, or 2x2 box.
+
+      3. First look for highly forced cells. If an empty cell has only one legal candidate
+      after checking its row, column, and box, fill it immediately and explain why
+      other numbers are excluded.
+
+      4. If no cell is obviously forced, scan each row, column, and 2x2 box for missing
+      numbers. If a missing number can go in only one empty position within that unit,
+      place it there and state that unit-level reason.
+
+      5. Prefer moves that reduce uncertainty and create new forced cells for the
+      next turn. A good move should make the remaining puzzle more constrained, not
+      more ambiguous.
+
+      6. Solve incrementally: choose exactly one placement, explain it briefly in
+      <think>, then output that one move in <answer>.
+
+      7. Never modify bracketed initial cells or already-filled cells. Only place
+      numbers into dots.
+
+      8. Avoid exploratory guesses when a forced move exists. In this environment,
+      reliable progress usually comes from constraint propagation rather than trial-and-error.
+
+      9. If a previous move was invalid or the board did not change, do not repeat
+      the same placement. Recompute legal candidates and explain the corrected constraint-consistent
+      choice.
+
+      10. Use row, column, and box agreement as confidence: the strongest placements
+      are those supported by multiple constraints at once.
+
+      11. Keep <think> concise but meaningful: identify the target cell, list or compare
+      its legal candidates, and give the decisive constraint.
+
+      12. Output only the required XML-like format and choose valid Sudoku placements.
+
+
+      You are solving a Sudoku puzzle. Fill in the grid so that every row, column,
+      and 2x2 box contains the numbers 1-4 without repetition.

+      \ push direction. A move that only repositions the player can be useful if it\

+      \ dead end unless that square is the target or clearly on the only path to the\
+      \ target.\n4. Prefer short plans that move the single box steadily toward the\
+      \ target; avoid wandering moves that do not improve player position or box position.\n\
+      5. If the box and target are aligned in the same row or column, try to keep\
+      \ the box on that line and push along it.\n6. If they are not aligned, first\
+      \ push to fix one coordinate, then reposition and push to fix the other coordinate.\n\

+    env_instruction: 'You are a careful 4x4 Sudoku solver. Use these reusable abstractions
+      when reasoning:
+
+      1. In <think>, explain the constraint logic behind the move, not just the final
+      placement. Mention which row, column, or 2x2 box makes the move safe or forced.
+
+      2. Treat each move as a constraint-preserving placement: place a number only
+      if it does not already appear in the same row, column, or 2x2 box.
+
+      3. First look for highly forced cells. If an empty cell has only one legal candidate
+      after checking its row, column, and box, fill it immediately and explain why
+      other numbers are excluded.
+
+      4. If no cell is obviously forced, scan each row, column, and 2x2 box for missing
+      numbers. If a missing number can go in only one empty position within that unit,
+      place it there and state that unit-level reason.
+
+      5. Prefer moves that reduce uncertainty and create new forced cells for the
+      next turn. A good move should make the remaining puzzle more constrained, not
+      more ambiguous.
+
+      6. Solve incrementally: choose exactly one placement, explain it briefly in
+      <think>, then output that one move in <answer>.
+
+      7. Never modify bracketed initial cells or already-filled cells. Only place
+      numbers into dots.
+
+      8. Avoid exploratory guesses when a forced move exists. In this environment,
+      reliable progress usually comes from constraint propagation rather than trial-and-error.
+
+      9. If a previous move was invalid or the board did not change, do not repeat
+      the same placement. Recompute legal candidates and explain the corrected constraint-consistent
+      choice.
+
+      10. Use row, column, and box agreement as confidence: the strongest placements
+      are those supported by multiple constraints at once.
+
+      11. Keep <think> concise but meaningful: identify the target cell, list or compare
+      its legal candidates, and give the decisive constraint.
+
+      12. Output only the required XML-like format and choose valid Sudoku placements.
+
+
+      You are solving a Sudoku puzzle. Fill in the grid so that every row, column,
+      and 2x2 box contains the numbers 1-4 without repetition.

+      when reasoning:
+
+      1. In <think>, explain the constraint logic behind the move, not just the final
+      placement. Mention which row, column, or 2x2 box makes the move safe or forced.
+
+      2. Treat each move as a constraint-preserving placement: place a number only
+      if it does not already appear in the same row, column, or 2x2 box.
+
+      3. First look for highly forced cells. If an empty cell has only one legal candidate
+      after checking its row, column, and box, fill it immediately and explain why
+      other numbers are excluded.
+
+      4. If no cell is obviously forced, scan each row, column, and 2x2 box for missing
+      numbers. If a missing number can go in only one empty position within that unit,
+      place it there and state that unit-level reason.
+
+      5. Prefer moves that reduce uncertainty and create new forced cells for the
+      next turn. A good move should make the remaining puzzle more constrained, not
+      more ambiguous.
+
+      6. Solve incrementally: choose exactly one placement, explain it briefly in
+      <think>, then output that one move in <answer>.
+
+      7. Never modify bracketed initial cells or already-filled cells. Only place
+      numbers into dots.
+
+      8. Avoid exploratory guesses when a forced move exists. In this environment,
+      reliable progress usually comes from constraint propagation rather than trial-and-error.
+
+      9. If a previous move was invalid or the board did not change, do not repeat
+      the same placement. Recompute legal candidates and explain the corrected constraint-consistent
+      choice.
+
+      10. Use row, column, and box agreement as confidence: the strongest placements
+      are those supported by multiple constraints at once.
+
+      11. Keep <think> concise but meaningful: identify the target cell, list or compare
+      its legal candidates, and give the decisive constraint.

+      12. Output only the required XML-like format and choose valid Sudoku placements.

+      \ push direction. A move that only repositions the player can be useful if it\

+      \ dead end unless that square is the target or clearly on the only path to the\
+      \ target.\n4. Prefer short plans that move the single box steadily toward the\
+      \ target; avoid wandering moves that do not improve player position or box position.\n\
+      5. If the box and target are aligned in the same row or column, try to keep\
+      \ the box on that line and push along it.\n6. If they are not aligned, first\
+      \ push to fix one coordinate, then reposition and push to fix the other coordinate.\n\

+    env_instruction: 'You are a careful 4x4 Sudoku solver. Use these reusable abstractions
+      when reasoning:
+
+      1. In <think>, explain the constraint logic behind the move, not just the final
+      placement. Mention which row, column, or 2x2 box makes the move safe or forced.
+
+      2. Treat each move as a constraint-preserving placement: place a number only
+      if it does not already appear in the same row, column, or 2x2 box.
+
+      3. First look for highly forced cells. If an empty cell has only one legal candidate
+      after checking its row, column, and box, fill it immediately and explain why
+      other numbers are excluded.
+
+      4. If no cell is obviously forced, scan each row, column, and 2x2 box for missing
+      numbers. If a missing number can go in only one empty position within that unit,
+      place it there and state that unit-level reason.
+
+      5. Prefer moves that reduce uncertainty and create new forced cells for the
+      next turn. A good move should make the remaining puzzle more constrained, not
+      more ambiguous.
+
+      6. Solve incrementally: choose exactly one placement, explain it briefly in
+      <think>, then output that one move in <answer>.
+
+      7. Never modify bracketed initial cells or already-filled cells. Only place
+      numbers into dots.
+
+      8. Avoid exploratory guesses when a forced move exists. In this environment,
+      reliable progress usually comes from constraint propagation rather than trial-and-error.
+
+      9. If a previous move was invalid or the board did not change, do not repeat
+      the same placement. Recompute legal candidates and explain the corrected constraint-consistent
+      choice.
+
+      10. Use row, column, and box agreement as confidence: the strongest placements
+      are those supported by multiple constraints at once.
+
+      11. Keep <think> concise but meaningful: identify the target cell, list or compare
+      its legal candidates, and give the decisive constraint.
+
+      12. Output only the required XML-like format and choose valid Sudoku placements.
+
+
+      You are solving a Sudoku puzzle. Fill in the grid so that every row, column,
+      and 2x2 box contains the numbers 1-4 without repetition.
+
+      Initial cells are shown in [brackets] and cannot be modified. Empty cells are
