  • Replace placeholder visuals with real CJ-S build photos.
  • Verify current supplier pricing and availability before recommending purchases.
  • Confirm workbook Helmholtz cells use the corrected end correction.
  • Keep acoustic values marked predicted until validation.csv contains measured rows.
  • Treat site previews, visual BOM layouts, and future generated images as non-authoritative unless visual-output-register.csv traces them to design-table/CAD authority.

01 · OverviewCajon Family Public-Review Prototype

cajon — concept render

This explorer is the studio-facing build packet for cajon. Sections below cover design, BOM, validation, the interactive acoustic model, visual authority, risks, capstone deliverables, and release gates for the box-percussion / Helmholtz packet.

Authority boundary

This is a pre-build V5 packet candidate. Panel thickness, joinery strength, snare preload, and strike response must be measured on the CJ-S prototype before production-ready claims.
