# Konghou Prototype Risks

## Structural Risks

- **Neck lean under cumulative string load:** Block paired-course work until the mule records loaded and unloaded deflection.
- **Bridge lift or soundboard cracking:** Use bridge and soundboard coupons before full stringing, then inspect after each proof-load step.
- **Pin rail splitting:** Drill and load-test pin coupons with the actual pin supplier before drilling the mule rail.
- **Anchor pullout:** Pull-test hitch pins or anchor hardware before using them in a loaded frame.

## Evidence Risks

- **String tension guessed from gauge alone:** Do not claim calculated tension until unit weight comes from the vendor or a measured sample.
- **Scaffold DXF mistaken for final CAD:** The included DXF is marked mule review only; replace it before paired-course cuts.
- **OpenSCAD scaffold mistaken for fabrication authority:** `cad/konghou-mule-load-path.scad` is an L2 review scaffold until every parameter traces to measured or reviewed data.
- **Concept images interpreted as dimensions:** Generated visuals are communication support only.
- **Material choice treated as settled too early:** `material-study.csv` records candidates and coupon gates; no frame, bridge, pin, or string material is proven yet.

## Readiness Risk

This packet is useful because it creates a canonical path, but it is intentionally not a final konghou plan. A future PR should promote the packet only after the mule build log contains real deflection, tension, and serviceability data.

- **Cultural authority overclaim:** Engineering language must not silently extend into traditional, authentic, heritage, or historical-reconstruction framing. See `cultural-provenance.md` for the authority statement and open cultural-review gate, and `public-readiness.md` for the polish-claim block list that binds every future PR and public-facing artifact.
