Offer the optional shared silkscreen dashboard: real solver events, candidate reasons, live/replay separation, fitted-model inspection and separately recorded detailed/5s replays. Audit every fitted body and every via/hole across the whole board, both faces, with coverage counts. Missing Fab geometry is not free space; native DRC does not establish fitted visibility. Keep unresolved labels explicit and do not apply an incomplete layout. Native geometry/edit/undo/refresh belongs to the EDA bridge.++## Visits++- 2026-10-18T22:59:33Z++## What the binary checked++### silkscreen++- **audit**: design/silk-audit-result.json+- **auditSha256**: 8b70dadb0291ffad9c55cf0e7c15674a1d752b8d868c4fa156c056304cc6beee+- **board**: ./aiflow-run/board-5.kicad_pcb+- **boardSha256**: 84b3b6a4807d6ef072794c66e1b65a74592695e721dec3b347c711e38745e244+- **collisions**: 0+- **footprints**: 38+- **footprintsCovered**: 38+- **input**: design/silk-audit.json+- **inputSha256**: ecb18b98d6498068e782f9dfa6ce251a6f01e423702ab7ebc3aace310c833aab+- **inventoryItems**: 57+- **labels**: 52+- **marks**: 52+- **nativeVerified**: False+- **note**: geometry audit of the supplied whole-board inventory; native DRC, label association and both native 2D/3D views remain required+- **obstacles**: 86+- **pass**: True+- **viaItems**: 19+- **vias**: 19++## Screenshots and drawings++**start**++![start](shot-silkscreen-1-start.png)++**visit 1-start**++![visit 1-start](shot-silkscreen-1-start.png)
