The creative half of corner-cases/alg-conv-trans-acc. Acc.rec is stuck on the variable a, and proof irrelevance admits any other proof of Acc (· < ·) 1 in its place, including one with a constructor at the head. Given both sides, a checker verifies this immediately; producing the right-hand side unprompted is the step no algorithm takes.
