Test "undecidability/subject-reduction-reduct"

Expected: 🤷 either · Size: 65.2 KB · Lines: 1.2 k · lean4export: 3.1.0 · Lean: 4.29.1 · 📄 Declaration · 🔗 Source

Beta erases the annotation of undecidability/subject-reduction-redex, and with it the middle term, leaving the two endpoints to compare: the conversion of undecidability/alg-conv-trans-acc. A term the kernel accepts thus reduces to one it rejects.
