The decommissioned grain silo north of the canal resembled a fortified bastion prepared for a protracted siege.
Ferra engineered the circular testing chamber with deliberate architectural paranoia, lining the curved perimeter with segmented ceramic tiles.
The volunteer masons interlocking the kiln-fired ceramic blocks refused to use traditional lime mortar, allowing the joints to flex and breathe under thermal expansion.
"A continuous stone surface reflects runaway resonance like an echo chamber," the forge artisan explained to the gathered volunteers.
"These segmented tiles deny the array a unified acoustic face, breaking rogue shockwaves into harmless warmth before they rebound."
Dozens of dockers and craftsmen from the outer districts hauled crates of copper wiring and bronze fittings into the chamber.
The liberated citizens adopted the testing silo as their personal civic project, working without overseers or municipal quotas.
