TLS-SMF: Terrestrial laser scans of an industrial test room (three epochs) and a cafeteria stress scene

Registered Leica BLK360 G1 terrestrial laser scans supporting the paper "TLS-SMF: ..." (Electronics, under revision, manuscript electronics-4525706). Three temporal epochs of one industrial test room — T1 (June 2026, showroom configuration, manual scan; plus the wall-removed export used as the semantic-processing input), T2 (July 2026, autonomous exploration scan), T3 (late July 2026, 99.6%-coverage exploration with a controlled-change protocol) — and a cross-floor cafeteria stress scene (August 2026). E57 format; multi-setup files carry registered per-setup poses. Ground-truth annotations, query benchmarks, and the processing pipeline are available at https://github.com/kkk3449/tls-smf. SHA-256 checksums included.
