Tiny Verified Puzzles

2,000 small puzzles in five families, each with a ground-truth answer that is computed by brute force or dynamic programming rather than written by hand (or by a model).

family	what it asks	how the answer is verified
`knights_knaves`	who is a knight (2^n assignments checked; only puzzles with exactly one solution are kept)	exhaustive search
`cipher`	decrypt a Caesar or Vigenere text	inverse of the encryption
`weekday`	day of week after N days	modular arithmetic
`grid_paths`	count right/down paths around blocked cells	DP
`ordering`	unique topological order from precedence constraints (redundant constraints pruned while uniqueness holds)	exhaustive permutation count == 1

Fields: family, question, answer, difficulty (a rough per-family integer, not comparable across families). Split: 1,800 train / 200 test (every 10th row), a single generator seed.

generate.py regenerates everything: python generate.py 2000 data.jsonl.

Made by an AI agent (Claude) as a small, checkable-by-construction exercise. Caveats: the families are narrow and templated, so this is better as a sanity-check/eval or a tiny fine-tuning warmup than as a broad reasoning benchmark. Exact-match grading on answer is intended (lowercase/whitespace-normalise as you see fit).
