Tally-stick checksums
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)
Tally-stick checksums. This joins medieval fiscal instruments to information theory. An Exchequer tally was a wooden stick notched with a debt's value and then split lengthwise, creditor and debtor each keeping half; the split's matching grain already authenticated the pair. The conjecture claims the sticks carried a second, unnoticed layer of security: that tally notch geometry encodes redundancy beyond face value — deliberate regularities in notch spacing, depth, or angle that do not carry the amount but would be disturbed by any later tampering with the notches. In modern terms these are anti-fraud bits, a checksum cut into a split physical token: alter a notch to inflate the debt and the hidden regularity breaks, exposing the fraud. If so, careful measurement of surviving tallies should reveal systematic non-value-bearing structure — geometry more regular than the recording of value alone requires.
Prediction clause (verbatim)
For each stick in a metrology of surviving tallies for non-value-bearing regularities, measure notch positions, depths, widths, and angles at sub-millimetre precision, and separate the features known to encode value from the residual geometry; test the residuals for systematic structure against a null of craftsman noise built by shuffling residuals across sticks. Primary clause: residual notch geometry must show statistically significant regularities (p < 0.01 after multiple-comparison correction) that recur across tallies from the same office and are consistent with a verification function; residuals indistinguishable from craftsman noise falsify the claim. The verdict follows the primary clause.
Kill-dataset (verbatim)
metrology of surviving tallies for non-value-bearing regularities.
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 scholarship. Kills and prior scholarship are credited here, by name, as they come in.

Provenance
Run: Imported conversation (verbatim harvest) · model: claude-fable-5
Origin: operator conversation with Claude Fable 5 at max effort, conducted 2026-07-03, relayed verbatim by the operator into the shepherd session on 2026-07-04. No ModelRun exists for the original generation (it happened outside the pipeline); this transcript file is the canonical capture. Transcript path: docs/generated/conjecture_harvest_fablemax_20260703.md. Model (operator-attested, not pipeline-recorded): claude-fable-5. Novelty disclaimer (verbatim, load-bearing -- rule 4): "Same caveat as before, doubled: at 100 items across all of archaeology and history, some of these will have cousins in the literature I can't check. What I can guarantee is the format — each links two things not normally linked, and each names the dataset or measurement that would kill it."
Novelty / leakage triage
anticipated in the literature — this exact test has never been run
The anti-fraud reading of tally design is published: denomination-coded notch widths plus the split stock/foil grain-and-notch match are framed in accounting history as an early internal control (wood can be removed but not invisibly added). The conjecture's distinctive claim — additional non-value-bearing regularities recoverable by metrological survey of surviving tallies — was not located as tested.
