Lebesgue Universal Covering Problem II · Computation and Reproduction Round 30 · A1 Replay & Backend Pinning 懸衡 (Xuán Héng) PARTIAL PASS

Round 30: the whole shard passes again here, and the second implementation's lower ledger comes back leaf for leaf from its own rule; that rule keeps one contact point per direction, so its thinnest leaf measures the rule's loss, not the geometry

PASS for the root replay (its intervals lie inside Round 28's, and this tree's brackets inside its own), marker 70's bound, all 9,278 lower leaves, the root correction, the lock's script digests and its libmp pin, and the shard's records; PARTIAL for the shard's implementation-level A1 on its upper half — the marker replay is Round 29's audit row, from a script that carries the emitter's support routine, normals and density.

PARTIAL · PASS This page is the second layer: the finite claims of the layer-1 document "Round 30 · A1 Replay & Backend Pinning" recomputed, its constructions reproduced, and its theorem-level steps read against the source. It does not rewrite the document and does not treat numerical results as proofs; the formal paper written from these two layers is the third layer, "III · Crystallization". Below are the recompute reports as written (byte for byte the research tree's), with their code and gate logs.
