Lebesgue Universal Covering Problem II · Computation and Reproduction Round 18 · Production Shard Checkpoint 懸衡 (Xuán Héng) PARTIAL PASS

Round 18: both checkpoints decode, re-prove and re-emit byte for byte; the tail forest is not Round 17's tail window, three conventions of the format are unstated, and the shipped verifier never reads the pending frontier

PASS for both checkpoints and the Rice events; PARTIAL for the grammar as specified and for the cost model's calibration.

PARTIAL · PASS This page is the second layer: the finite claims of the layer-1 document "Round 18 · Production Shard Checkpoint" 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.
