PROOF MATERIALS ON ALIYUN — 2026-10-15 Reader: https://proofs.vibe-think.com/checkpoints/#UD/H1 Paper list: https://proofs.vibe-think.com/papers/ Eight questions: UD: Unit distance (H1–H5) EP-1: Berenstein rigidity (H1–H5) KT-1: Amphicheiral knot polynomials (H1–H6) NE-1: Periodic BBM (H1–H4) OA-1: Scalar Crouzeix inequality (H1–H5) OA-2: Groups with isomorphic factors (H1–H6) SM-1: Jamming exponent identity (H1–H5) SP-1: Quartic SYK spectral edge (H1–H6) 42 endpoint statements; 133 Hi-to-Hj evaluation tasks (15 unit-distance + 118 other). Targets do not supply intervening checkpoint assertions. Each transition grants only its named start.
