Muqarnas as diffusers

Status: Prior

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).

This is a proposed connection between two domains, generated by a language model. It is not an article and not evidence: it sits below the evidence/publication boundary. A quantitative prediction and a named kill-dataset are attached (when registered) so the claim stays falsifiable rather than merely evocative.

Claim (verbatim)

Muqarnas as diffusers. Muqarnas vaulting measurably evens the reverberant field for recitation compared to smooth domes of equal geometry — ornament with an acoustic function. Falsify: paired measurements in Iranian mosques.

Kill-dataset (verbatim)

paired measurements in Iranian mosques.

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

Leaked (already exists in the literature)

The core join is directly published: a computational study (Al Jumaily 2017, full-text-confirmed by the dossier) models muqarnas configurations as sound-scattering elements and concludes they improve the hearing state, and an in-mosque measurement study at the Yazd Jaame mosque reports lower reverberation time with muqarnas/squinch configurations (median RT ~3.33s vs ~4.32s without). The harvest's exact falsification design (paired comparison against a smooth dome of identical geometry) was not confirmed as performed, but ornament-with-acoustic-function is established.
