Hulusi Print Packet

Shop-floor bridge for the existing PDF and Markdown packet. Use this page to orient quickly before cutting, voicing, or recording validation data.

Readiness boundary: this packet is ready for HUL-P0/HUL-P1 bench trials, but it is not measured build evidence. Reed pull-down, pipe correction, ergonomic hole shifts, and production CAD exports still require prototype data.

Bench Loop

Confirm workbook inputs and re-export any derived shop sheets that changed.
Cut HUL-P0 reed coupons and record off-pipe pitch before committing to full pipes.
Build HUL-P1 melody pipe and compare all seven notes against validation.csv.
Update pull_down_cents and correction_pct only from measured prototype evidence.
