Status: L2 V5 build-packet candidate.
cad/v2-dxf-starter.dxf and drawings/pipa-v5-starter.dxf are the only fabrication-authority artifacts in this packet, and only for prototype front-layout review. Generated imagery and prompt briefs are concept-only. cad/pipa.scad and wolfram/fret-scale-study.wl are source-only until measured inputs and runtime evidence exist.
Do not use this packet for final fret cutting, rear shell carving, pegbox side-profile fabrication, CNC body machining, or production quotes as final geometry.
