Partially verified: the curator re-read S14, S18; S15, S22, S24 were not re-read by the curator and rest on the producer's pinned reading. COLMAP asks for high visual overlap with each object seen in at least 3 images; Meshroom asks for 60% side and 80% frontal overlap, no flash, fixed focal length and no shadows, reflections or transparent objects. Metashape's overlap figures (60/80% aerial; 60-70% close range) and its no-crop/rotate rule are producer-read only. Curator qualifications: Partially verified: the curator re-read S14, S18; S15, S22, 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): S15: HTTP 200, bytes differ from the producer pin; S22: 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 manual (8.5 MB) not re-fetched; COLMAP SIFT/ALIKED and EXIF details not re-located. 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.
