Colosseum egress codes
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)
Colosseum egress codes. The Colosseum moved crowds of tens of thousands through its vomitoria — the numbered entrances and radiating stair-and-corridor system that gave the building its famously fast turnover. Modern stadium safety codes make crowd egress a precise engineering quantity: evacuation-time standards, flow rates per metre of exit width, and agent-based simulation tools that test a floor plan against moving crowds. The conjecture is that the Flavian architects, iterating on centuries of amphitheatre design without any of this theory, converged on the same solution: run a modern agent-based egress simulation on the Colosseum's actual plans, and the predicted evacuation times should meet modern stadium standards. Safety engineering was achieved by iteration long before it was achieved by calculation — and the vomitorium system should pass a code written nineteen centuries after it was built.
Prediction clause (verbatim)
Run agent-based egress simulations on the Colosseum's actual documented plans (vomitoria widths, stair dimensions, corridor network) at full attested capacity, using standard pedestrian-dynamics parameters. Primary clause: simulated total evacuation time meets the modern stadium benchmark of full egress within 8 minutes in the majority of runs, with no persistent choke points exceeding critical crowd density. The verdict follows the primary clause.
Kill-dataset (verbatim)
agent-based egress simulation on the actual plans.

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
already answered in the literature
The strongest leak class: the conjecture's named falsification test has already been run — a 2022 peer-reviewed simulation compares Colosseum evacuation (agent/flow modeling of vomitoria and stairs, specific flow ~1.14 person/s/m) against a modern arena (Gazprom Arena) and reports the Colosseum meets current evacuation standards, which is the conjecture's predicted outcome. In effect the claim is both anticipated and already supported in the literature.
