Moiré Superconductivity From Precursor To Onset: A Frozen-Corridor Contract With Flip-Only Audits

Significant — This front-end materials superconductor lattice manuscript treats the source claim class "superconductivity emerges from a named correlated precursor state” in twisted graphene moire systems as a three-witness object (precursor, onset, and a direction-audited linkage) and supplies a contract overlay that converts the narrative into a replayable decision row with outcomes {accept, downgrade, refuse}. The corridor is frozen by a pad/corridor hash discipline that forbids threshold travel and post-view authority changes; tightening is replay-only; multi-zone handling is tokenized; and missingness/leakage are charged explicitly through STLF and SoZ so clean plots cannot be manufactured by starvation. The linkage witness is enforced via sunrise–sunset audit and, where applicable, flip-only schedules with a mandatory Z=0 anchor; disable-L is included as a falsifier targeting the coupling pathway rather than the existence of precursor/onset in isolation. The deliverable is durability: promotion is allowed only if the precursor-to-onset linkage survives swaps, falsifiers, and tightening under published token scripts; otherwise the output is downgraded or refused without rewriting the mechanism story.
