TSUNAGI_20constant

TSUNAGI AT 20×20: 64 levels in blocks of 16, easiest first by the measured difficulty (difficulty.ts), each block's 15th and 16th its twist.

WRITTEN BY node scripts/tsunagi-levels-huge.ts, NEVER BY HAND, from the pool node scripts/tsunagi-reduce-pool.ts makes. Each line is one level: its layout (a character for each pair's two stones, . for an empty cell) and its one answer (the character of the line through every cell). Every level is proved to have exactly one answer by levels.test.ts, no two are the same board under a turn or a mirror, and difficulty.test.ts holds the order to the measure.
