EXP-0010 — Rhyme structure: verse-final ending runs vs shuffled order
completed Deterministic computation
Question
Do ayah endings cluster in reading order (sustained rhyme) beyond what their own inventory of endings produces under random order?
Hypothesis
Strong ordered rhyme expected in many surahs (saj' is audible); the experiment measures where and how strongly, not whether rhyme exists.
Counting policy
Rhyme unit = last 2 letters-basic characters of each ayah's final token; per-surah mean run length; null = in-surah order shuffles with the repo PRNG (seed 20260814, 2000 draws); surahs under 10 ayahs excluded. Cross-text baselines (Bukhari, al-Mutanabbi) deferred to a follow-up spec.
