Performance rides on the back of the page
Status is derived only from the shepherd-authored triage/prediction data above -- community submissions and claims are a separate overlay and can never change it (see the participation panel below).
Claim (verbatim)
Among the Dunhuang manuscripts, popular performance narratives keep turning up on the backs of expired official documents and on re-used paper, while devotional sutra copies sit on fresh sheets. The connection is between physical support and position at the oral-written interface: a performance text was a private prosthesis for a voice โ provisional, personal, disposable โ so it took whatever surface lay to hand, whereas a sutra was itself the sacred object and demanded a proper body; the choice encodes function, not merely thrift. The support of a manuscript thereby becomes a genre detector independent of content: verso and re-use rates flag the performance circuit. If this holds, survival counts at Dunhuang cannot be read as popularity rankings without correcting for the re-use channel, which preserved and discarded performance texts on a different schedule from books.
Prediction clause (verbatim)
Census the physical support of narrative performance texts versus commissioned sutra copies in the same deposit. Primary clause, which decides the verdict: at least 50% of bianwen and transformation-text copies stand on re-used paper (verso of an earlier text or document), against no more than 15% of sutra copies.
Kill-dataset (verbatim)
IDP, the International Dunhuang Programme: its catalogue records and images showing recto/verso contents and paper re-use for the performance-text holdings and for sutra copies from the same deposit.
Nobody has run this test. The kill-data is named above. If you can run it — or you know the paper that already settles it — claim the kill or submit the prior. Kills and priors are credited here, by name, as they come in.

Novelty / leakage triage
anticipated in the literature โ this exact test has never been run
Mair's inventory of lay-student manuscripts and studies of Dunhuang manuscript reuse document performance narratives on versos and recycled paper (e.g., the Mulian verses on the back of P4524), so the pattern is known qualitatively. The formal two-population census with re-use rate thresholds against sutra controls has not been run.
