Books Older Than Their Paper
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)
The physical Maya codices are Postclassic objects, but astronomical tables must anchor themselves to absolute dates, and anchors fossilize: a copied table drags its original entry dates along with it, patched by correction increments rather than recomputed from scratch. So the distribution of internal calendrical anchor points across the four codices, compared against their accepted manufacture windows, measures the depth of the copy chain — how many centuries of lost exemplars stand behind each surviving page. The mechanism is scribal economics and authority: a working table's value is its pedigree, so scribes adjust the entry point and preserve the structure, leaving the old anchors embedded like tree rings. If the conjecture holds, the statement 'four books survive' becomes 'four lineages survive,' each with a measurable length, and the lost exemplar chain becomes a quantity rather than a guess.
Prediction clause (verbatim)
Extract all securely readable calendrical anchor dates from the facsimiles of the four codices and compare them with each codex's accepted physical manufacture window. Primary clause (the verdict follows it): at least two of the four codices contain anchor dates more than 200 years earlier than their manufacture window. Secondary clause: the earliest anchors cluster in the Classic period rather than scattering uniformly, indicating copy chains rooted in Classic-period originals.
Kill-dataset (verbatim)
FAMSI codex facsimile corpus: the facsimiles supply the readable calendrical anchor dates for all four Maya codices.
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
That the Postclassic codices copy far older (Classic-rooted) astronomical materials and carry deep base/anchor dates is a mainstream view, but quantifying copy-chain depth by systematically comparing internal calendrical anchors against physical manufacture windows as a 'tree-ring' lineage measure is an un-run operationalization. Thin field.
