Name	Kind	What it is
`checkHitori`	function	Checks unshaded row and column duplicates, adjacent shades, and white connectivity.
`decodeHitori`	function	Read a native saved Hitori game, or null for invalid board data or progress.
`encodeHitori`	function	Versioned public clue and mark data; the generated answer is not saved.
`generateHitori`	function	Makes a seeded puzzle and proves its answer is the only one.
`hintHitori`	function	Gives one next shade in the unique minimal solution, if uniqueness was proved.
`HITORI_LEAST_SIDE`	constant	The minimum supported Hitori board dimension.
`HITORI_LEVELS`	constant	How hard a puzzle is made, by what a person must do to solve it; see `rateHitori`.
`HITORI_MAX_NODES`	constant	The native Hitori search-node budget.
`HITORI_MOST_ATTEMPTS`	constant	The native Hitori generation-attempt limit.
`HITORI_MOST_SIDE`	constant	The maximum supported Hitori board dimension.
`HITORI_SIZES`	constant	The sides on offer; any side from 4 to `HITORI_MOST_SIDE` is a board `isHitoriBoard` takes.
`HitoriBoard`	type	Hitori dimensions and printed clues in their native row-major representation.
`HitoriGame`	type	The immutable Hitori board, current entries or marks, undo history and assistance state.
`HitoriLevel`	type	A native difficulty tier for generated Hitori puzzles.
`hitoriNeighbors`	function	Read orthogonally adjacent cells on a square Hitori board.
`HitoriPuzzle`	type	A seeded Hitori board with its verified solution and native difficulty tier.
`HitoriRating`	type	How hard a board is, measured by solving it.
`HitoriSolve`	type	A bounded Hitori solve result: answer count, first solution, node work and whether the search completed.
`isHitoriBoard`	function	Whether the value has valid native Hitori dimensions, clues and data.
`newHitori`	function	Create the initial immutable Hitori game from a valid board.
`rateHitori`	function	Rates a board with one answer by solving it: with the plain rules, with the whites-stay-together rule, then by supposing.
`restartHitori`	function	Return the Hitori game reset to its initial entries or marks.
`shadeHitori`	function	Apply the requested native Hitori entry or mark to a new immutable game; invalid or fixed targets stay unchanged.
`solveHitori`	function	Counts distinct minimal shade patterns: an answer shades only squares that settle a duplicate, so extra shades are never a second answer.
`undoHitori`	function	Return the Hitori game with its previous marks or entries restored, or unchanged when there is no undo history.
