Reproducible LSOG mapping for Maine: design-based estimation, an FIA-anchored 10 m product, and an apples-to-apples comparison with the Hagan et al. (2026) LiDAR map

v4.1.0 (2026-06-27): Ecosphere Comment + Maine LSOG package. Adds the finalized Ecosphere Comment (Hagan reproduction and reanalysis) and SI and the Maine accessibility-window figure, alongside the Maine-only LSOG raster products. The regional multi-state manuscript and products are in the companion record (10.5281/zenodo.20836852). v4.1.1 (2026-06-27): TreeMap any-LSOG reported as a range across vintages and class-assignment conventions. v4.2.0 (2026-06-28): red-team corrections. Accessibility window reported at both the 400 m (Hagan stated) and 800 m buffers; scope-of-inference argument hardened with survey-sampling and spatial cross-validation citations; references re-alphabetized. v4.2.1 (2026-06-28): citation corrections (Lohr 2022; Woodall and Weiskittel attribution), data-availability cites the open-access version DOI, and a concision pass.
