Graffiti thread depth
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).
“Anticipated in print” means the direction of this claim already appears in scholarship, while this exact test has never been run — it records prior art, not proof; nothing here counts as supported or falsified until a registered resolution says so.
Claim (verbatim)
Graffiti thread depth. The walls of Pompeii preserve genuine written conversations: graffiti that answer, mock, and extend earlier graffiti on the same surface, recorded in CIL IV. Modern online forums show a robust statistical signature in how such exchanges unfold — the distribution of reply depths, meaning how many turns a thread runs before it dies, follows a characteristic rapidly decaying form driven by attention and diminishing engagement rather than by the medium. The conjecture is that this signature is a conversational universal: reconstructed Pompeian wall dialogues should follow the same reply-depth distribution as modern forum threads. If human back-and-forth has invariant statistics, then two millennia and a change of medium from plaster to pixels should not alter the shape of the curve.
Prediction clause (verbatim)
Using the CIL IV thread reconstruction, identify Pompeian graffiti that respond to other graffiti on the same wall, chain them into reply trees, and record each thread's depth; fit the resulting reply-depth distribution and compare it against depth distributions from modern forum thread corpora. Primary clause: a two-sample Kolmogorov-Smirnov test fails to reject identity of distributional form at p > 0.05, and the fitted decay parameter of the graffiti threads falls within the range fitted across modern forums; a clear rejection on both counts kills the conjecture. The verdict follows the primary clause.

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
Pompeian graffiti dialogues are documented philologically as genuine multi-party reply chains (Benefiel), forum reply-depth distributions are quantified in network science (power-law degree exponents ~3.3-4.2), and the cultural analogy is drawn qualitatively; the statistical comparison of CIL IV reply-depth distributions against modern forum distributions was not located.
