The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We establish a consistency chain from the tree-level QED prediction through truth-level and detector-level reconstruction, yielding a reconstructed concurrence of 0.279 ± 0.007 with the good-solution approach.

C2weakest assumption

The Monte Carlo simulation and the good-solution reconstruction method accurately capture detector effects and spin correlations without introducing bias or post-hoc adjustments that would invalidate the reported concurrence value.

C3one line summary

Monte Carlo simulation at the proposed STCF reconstructs a concurrence of 0.279 ± 0.007 for tau+ tau- pairs in the pi pi channel, showing feasibility for quantum entanglement studies.
