Pipeline and architecture

The pipeline reconstructs registration, feature encoding, coreset memory bank, and kNN scoring for the PCB inspection setting.
The architecture figure shows a PCB ROI converted into patch tokens and routed through a transformer encoder plus MLP head.

Tables and claim boundary

Record types: research pilot records and method/result diagrams. Production-evaluation criteria: camera input, gold-label comparison, and defect-detection performance.

The result table keeps the FR-PatchCore/PatchCore-style table layout while separating PCB inspection values from claim boundaries.
