I was inspired to try setting this puzzle as a 'deconstruction version' of the fantastic puzzle Unique Values by Mesmer. (In fact, Unique Values was my first introduction to variant sudoku--thank you Matt!)

Rules:

• Deconstruction: the grid contains nine non-overlapping 3x3 regions which you must locate. Each region contains the digits from 1 to 9 with no repeats. Each row and column of the entire 11x11 grid also has no repeated digits.
• The 'value' of a cage, cell, or collection of cells is the sum of its digits, where an empty cell contributes 0.
• Region sum cages: no two cages have the same value. If a single cage intersects multiple regions, its restrictions to each region have the same value.
• The two inequalities between cells point to the smaller value. The cage labelled '<14' has a value strictly less than 14.
