pass rebuild canonical carapace prompt from requested wording · 0.6 s · raw log$ pnpm data:build

fail generate four carapace takes with local Stable Audio · 0.2 s · raw log

$ ./tools/sfxgen --prompt Single isolated weapon contact against a hard insect carapace: sharp dry chitin crack followed immediately by a hollow shell knock. Brittle, rigid, insect-shell texture with a short natural decay. Material contact only — no weapon swing, no whoosh, no large impact boom, no sub-bass, no music, no voices, no ambience. One impact only near the beginning, followed by silence. Clean immediate attack, dry close sound, reverb tail under 0.3 seconds. --seconds 0.3 --takes 4 --out audio/source/combat-core/sfx-material-carapace.mp3
