General fix: enforce strict runtime validation of computed indices before any property access/assignment, so only safe integer indices
0..7are ever used. This prevents special keys (__proto__,constructor,prototype) and other non-integer/coerced values from reaching assignment sinks.Best fix here (without changing functionality): strengthen
resolveinsrc/board.tsto reject non-integer numeric tuple values usingNumber.isIntegerbefore range checks. This keeps existing API/behavior for valid inputs (strings resolved bysquareToIndices, or numeric tuples) while closing prototype-pollution-style dynamic key abuse paths. No new imports or dependencies are required.
