1925-2025 Namsan Chōsen Jingū: Field Survey and Stone Structure Documentation (Centennial Evidence Package v1.0)

“This is v0.1; v1.0 will follow in 2026 as a versioned update” Abstract (English) This working paper is a Research Artifact Package that seals and structures field evidence related to the former Chōsen Jingū (Namsan, Seoul; established 1925) in the centennial year of 2025. The package provides reproducible documentation—GPS coordinates, comparative photographs (c. 1920s vs. 2025), frame-based evidence from pre-1962 films, an official correction letter regarding mislabeling in the Seoul Station centennial exhibition, and a centennial timestamp captured on 2025-10-15. Rather than presenting a finalized historical monograph, the goal is to fix provenance and integrity (public timestamp + SHA-256 hashes) and to offer a verifiable foundation for peer review, documentary production, exhibitions, and future research versions.
