Prototype-planning boundary

This explorer organizes the repo's current floor-harp packet, but it is not fabrication authority by itself. Build dimensions still need a reviewed string schedule, load-path analysis, and CAD or full-size drawing authority before the packet can move beyond L2.

Current packet basis
22-string L2 prototypeREADME.md and design.md define the current C3-C6 planning boundary.
Legacy design table
34-string workbookfloor-harp-design-table.xlsx is useful reference evidence, not the current validated string schedule.
Missing authority
CAD and load reviewcad/ and drawings/ are starter folders; no browser-renderable CAD or reviewed DXF is present.
Validation state
TBD measurementsvalidation.csv records required checks, with measured fields intentionally left TBD.
