11 bounded physical-evidence records.
Publisher independence, identity precision and measurement scope vary by row. Results remain bounded by the disclosed specimen, setup, workload and metric; an inconclusive mapping is evidence associated with the catalog model, not verification of a manufacturer claim.

| Range-resolution versus repeatability boundaryrange_resolution_review | Millimetre-to-centimetre repeatability dispersion observed; intrinsic resolution not isolatedThe paper reports standard deviation and RMSE at several ranges and materials; those statistics are not the datasheet’s quantization/resolution metric. | inconclusiveObserved standard deviation and RMSE characterize repeatability and error, not the datasheet’s distance-dependent quantization/resolution metric; the claim remains unresolved. | Characterization and calibration of multiple 2D laser scanners ↗Sections 4.1–4.3, Tables 2, 4 and 6 Checked 2026-08-24 |
| Observed host-interface boundarydata_interface_review | Scanner interfaced to ROS through USBThe study reports the host-facing USB path; it does not isolate whether an adapter bridges the scanner core’s 115,200 bps UART. | inconclusiveThe study validates a host-facing USB path into ROS but does not isolate the scanner core’s UART or confirm 115,200 bps, so the adapter boundary prevents direct support. | Characterization and calibration of multiple 2D laser scanners ↗Section 3.2 experimental setup Checked 2026-08-24 |

Known limits
What this record does not prove.
- The 12 m range claim is target-conditioned; it is not a universal detection distance.
- The OpenAMR source has not confirmed the exact A1 submodel sticker, so no exact robot crosswalk is released.
- No RCI serialised-device or robot-level scan test exists.
