<b>From Adjacency to Pair Coherence in the Qur'an : </b><b>A Reproducibility Dataset for Testing ʿAmūd Alignment, Complementarity, Placement, and Negative Controls</b>

<p dir="ltr">This dataset develops a reproducibility framework for testing whether two adjacent Qur'anic surahs form a coherent pair rather than merely standing next to one another in the received order.</p><p dir="ltr">The Qur'an contains 113 adjacent surah relationships, but adjacency alone does not establish pair coherence. This research object therefore treats those 113 relationships as a comparison universe and asks what additional evidence is required before a pair claim can be accepted.</p><p dir="ltr">The framework evaluates proposed pairs through several evidentiary dimensions: ʿamūd alignment, functional complementarity, opening and closing relationships, placement logic, mutual illumination, specificity, counterevidence, negative controls, and proportional confidence grading.</p><p dir="ltr">Six possible forms of pair relation are distinguished: complementarity, contrastive balance, burden completion, scale transfer, mirror relation, and witness-response relation.

These categories are not assigned automatically. A pair must demonstrate a specific structural relationship that explains both surahs more effectively when they are read together.</p><p dir="ltr">A central test is mutual illumination. A strong pair should clarify both surahs rather than allowing one surah to carry the entire interpretive argument.
