The theater fraction
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 theater fraction. Service-capacity planning sizes a facility to a fixed fraction of the population it must serve at peak; this conjecture claims Greek cities did the same with their theaters. If theaters were built to seat a set percentile of the citizen body — a shared civic capacity rule — then seat counts are a fossilized census, and the ratio of theater capacity to city population should be nearly constant across the Greek world. Across dozens of poleis with measured capacities and independent population estimates, that ratio should cluster tightly in the 0.10-0.20 band, with scatter markedly tighter than the loose population-to-walled-area scaling on the same cities — making seats a sharper demographic proxy than walls or any other urban size measure. Pan-Hellenic sanctuary theaters, sized for festival crowds rather than resident citizen bodies, should stand out as extreme outliers — the exception confirming the rule. Scatter as wide as the other proxies kills it.
Prediction clause (verbatim)
Across >= 30 poleis with measured theater capacity and independent population estimates, the ratio of capacity to estimated total population clusters in 0.10-0.20 with a coefficient of variation <= 0.35, tighter than the CV of population-to-walled-area scaling (>= 0.5) on the same cities; pan-Hellenic sanctuary theaters stand out as > 3-sigma outliers. Scatter as wide as other proxies kills it.

Provenance
Run: Fresh agent generation · model: claude-fable-5
Generated by a fresh Fable-tier instance at maximum effort with generation-first blindness (no repo/web/DB access); titles-only knowledge of existing items, embedded in titles_supplied per the batch-2 lane rule; prompt pre-committed in docs/GOAL_CONJECTURES_BATCH3_20260705.md (b043140). Novelty unverified by construction. titles_supplied stripped to the committed sidecar conjecture_fresh_fablemax_batch3_titles_supplied_20260705.md at import (schema additionalProperties:false; relaxation queued).
Novelty / leakage triage
already answered in the literature
A near-direct precedent exists: a settlement-scaling study of entertainment-structure capacities across 238 Roman-Empire sites explicitly treats seating capacity as a population proxy and reads deviations as socio-economically meaningful — the conjecture's move on the same object class. The Greek-polis-only band, CV comparison, and sanctuary-outlier clauses were not located, but the connection is published.
