# Verification summary — connected prototype

**CAD layout and print exports checked. Physical qualification remains open.**

| Gate | Result |
|---|---|
| Original exterior | 78 × 150 × 24 mm nominal retained. Original84 classified shell faces, opening/seam outlines and unchanged external components compared. Ambiguous CAD trim representation resolved within1.1µm numerical tolerance. |
| Final finishing changes | Three sealed voids filled; PTT pad clearance restored; PCB stop root broadened inward. All change volumes remain inside the protected outer skin. |
| Print files |21 watertight, consistently wound, single connected meshes in mm; matched to individual CAD solids. Native archive reopened and all21 identities verified. |
| Rigid assembly | No unresolved modeled part/part, purchased-part/part, hardware/electronics or PCB/part interference. One raw Boolean PCB flag resolved by independent1.449mm separation. |
| Connected wiring | All seven interfaces represented. No unexpected physical route/part, route/electronics or wire-pair overlaps. Wider dressing volumes checked separately. Intended termination contacts are explicitly classified. |
| Soft stock |45 retained installed stock groups after removal of three obsolete films. Retained PTT rear pad has its own open clearance. |
| Controls |28 translation samples,32 edge-rocking probes and six simultaneous end-of-travel pairs checked. No unexpected modeled contacts. Physical switch actuation/return is untested. |
| Access |22 fasteners checked with a Ø3×30mm shaft in their documented assembly stages. Internal screws are fitted before the PCB/halves join. |
| Structural review | Local diagnostic beam/roof calculations and inherited control screens provided with explicit material/load assumptions. These are not process-specific strength certificates. |

## How the final geometry is tied to the checks

The full assembly was screened before a small local P01 finishing correction. Before_Local_Finish preserves that exact manifest, assembly index, motion and exterior evidence. The finishing-delta audit checks all added material against every retained physical/reservation group and each sampled control pose; removed material clears the PTT pad. All other printed parts, hardware, electronics and harness geometry are unchanged. The final native archive and meshes were then exported from the updated assembly and independently checked. FINAL_VERIFICATION_SUMMARY.json records the hashes.

The raw0.8mm inner-band comparison records internal support changes and CAD Boolean ambiguity; it is preserved for transparency and is not silently relabeled a pass. The actual constraint is the original exterior and external opening outlines, established by the original-face check and the finishing-delta protection proof.

## Remaining physical gates

Use the specified microphone cable and thin non-battery harnesses. Confirm the factory battery’s protected lead exit and excess length dress naturally into the available space; tape must stay on stationary lands within the documented thin-stock allowance. Received switch travel/force, solder insulation, USB shoulder height, PCB/foam variation and real assembly paths remain first-article checks. CAD does not establish electrical continuity, optical brightness, acoustic quality, radio performance, print strength or cycle life.

Install all connections together, seat the case by hand, test USB and every control, complete ten service cycles and1,000 actuations per control, and record functional results. Golden remains unchanged.

## Presentation update

The external USB cable-shoulder gauge is hidden in the exterior, connected-interior and front-mechanism review images, and hidden by default in the native Fusion archive. It remains available as an engineering reference for USB fit checks. The reopened archive preserves all21 printed solids and all181 group placements. Individual STL/STEP geometry and the full engineering reference STEP are unchanged. See presentation_visibility.json.
