A panel of models attacks your problem with the literature, SageMath, PARI/GP and an SMT solver, then formalises the result in Lean 4 against Mathlib. Lean's kernel either accepts the proof or it does not, and no amount of confident prose changes that. When it fails you get the exact goal that remains, which is usually where the informal argument was hand-waving.

A mai duba wanda ba za a iya yaudarar

Lean 4 with Mathlib type-checks the final statement, and a proof that leans on sorry, native_decide or a fresh axiom is rejected rather than counted. Alongside it: SageMath, PARI/GP, Z3, CVC5 and the OEIS, so a construction can be computed and identified before anyone tries to prove anything about it.
