Partially verified: the curator re-read S14, S15, S20, S21; S16, S24 were not re-read by the curator and rest on the producer's pinned reading. COLMAP's automatic reconstruction writes a fused.ply dense cloud and Poisson and Delaunay PLY meshes, with texturing as a separate mesh_texturer step producing an atlas with per-face UVs; Meshroom's Texturing writes texturedMesh.obj/.mtl and texture_*.png, prefers Alembic for point-cloud interchange and has FBX support paused. Metashape's export list is producer-read only.

Curator qualifications: Partially verified: the curator re-read S14, S15, S20, S21; S16, S24 were not re-read by the curator and rest on the producer's pinned reading. Curator GET 2026-10-23 of the sources not re-read (mechanical source evidence, not semantic verification): S16: HTTP 200, bytes differ from the producer pin; S24: HTTP 200, bytes equal to the producer pin. Docs read 2026-10-22; no reconstruction run. Metashape export list not re-read; COLMAP format.rst (S16) not re-read.

Limitations: Docs read 2026-10-22; no reconstruction run.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
