The administered reed
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)
Papyrus production was a concentrated, licence-hedged Egyptian industry with a Ptolemaic monopoly in its ancestry; wheat was the freest market the ancient world had. Join them through price behaviour: papyrus prices should look administered — nominally rigid for decades, then jumping in steps, and nearly identical across distant districts in the same year — while wheat prices in the very same documents bounce with every harvest. Concentrated producers and customary tariffs make sticky prices; atomistic markets make flexible ones, and the papyri record both regimes side by side. If this holds, the ancient book world's key raw material was priced more like a state utility than like a crop, and papyrus price attestations must be read as posted tariffs rather than market clearings.
Prediction clause (verbatim)
Primary clause (carries the verdict): the median run-length in years between changes in attested nominal charta prices is at least 3x the median run-length for wheat prices in the same corpus and period. Secondary clause: cross-district same-year price dispersion for charta is less than half that for wheat.
Kill-dataset (verbatim)
papyri.info (in-house) price series for charta and wheat; the kill is a statistical run-length and dispersion test on non-codex documentary evidence.
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 — this exact test has never been run
Papyrus's concentrated, monopoly-descended Egyptian industry versus the freest ancient market (wheat) is well characterized, and price-behaviour studies exist, but the specific 'administered price' test—charta nominal-price run-lengths >=3x wheat's and lower cross-district dispersion—is un-run.
