Release gates
  • HUL-P0 reed-coupon measurements are still required before claiming reed pull-down calibration.
  • HUL-P1 melody-pipe measurements are still required before treating the pipe and finger-hole model as validated.
  • Production CAD, DXF, STEP, STL, and G-code remain deferred until measured prototype data supports them.
  • Concept images should be replaced with shop photos before public-release presentation.

01 · OverviewHulusi (葫芦丝) — Wooden Cucurbit Free-Reed Flute Family (HUL-001) — Build Packet

hulusi — concept render

The hulusi lineage is credited to the Dai people of Yunnan, with related instruments across nearby communities and regions; this repo documents a modern wooden workshop interpretation rather than a traditional artifact claim.

Readiness boundary

This explorer is a showcase and navigation layer. Fabrication authority still comes from the workbook, design table, drawing files, and measured validation records. HUL-P0 and HUL-P1 measurements are still pending.
