Beacon channel capacity
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)
Beacon channel capacity. The Byzantine empire ran a fire-signal chain that could relay news of Arab raids from the Cilician frontier to Constantinople within hours — a communication channel in the exact information-theoretic sense, and one operating under noise, since fog and haze could blind any single link. Information theory says a designer maximizing reliability under noise buys redundancy: overlapping viewsheds and backup sight-lines, at the price of extra stations. The conjecture is that the attested beacon sites reflect precisely this trade: the chain sits at viewshed-redundancy optima under a fog-noise model, using more stations than the bare minimum needed to connect the endpoints, with the surplus positioned where outage risk is highest. The Byzantines, in other words, engineered channel reliability, not station economy.
Prediction clause (verbatim)
Using GIS viewshed analysis over digital elevation models, compute the attested beacon chain's end-to-end transmission reliability under a fog-outage noise model, and compare it against alternative sitings: the minimum-station connecting chain and an ensemble of random feasible chains with the same station count. Primary clause: the attested chain uses more stations than the minimum yet achieves higher modeled reliability than the minimum-station chain and ranks in the top 10% of the equal-count random ensemble. The verdict follows the primary clause.
Kill-dataset (verbatim)
GIS viewshed analysis vs alternative sitings.
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.

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
Viewshed-GIS testing of the actual Byzantine beacon chain is published, documenting terrain-dependent spacing (~97 km open Anatolia vs ~56 km broken Bithynia) — the enabling analysis on the exact object. The optimization framing (siting at reliability-under-fog optima versus station-count minimization, tested against alternative computed sitings) was not located.
