Version 1.6 Description DOI: https://doi.org/10.5281/zenodo.21149543 This record is Version 1.6 of the discussion paper. It updates Version 1.5, DOI: https://doi.org/10.5281/zenodo.21032259. Title: Reframing Japan’s Photon Science Knowledge Infrastructure and Circulation for the SPring-8-II Era Subtitle: User-Centric and AI-Enabled Support across Complementary Photon Science Facilities Version 1.6 is a substantive clarification and consolidation of the knowledge-infrastructure argument developed in Version 1.5. The central position remains unchanged: SPring-8-II should be treated not only as a major source upgrade, but also as an opportunity to redesign user support, complementary facility use, data workflows, knowledge infrastructure, and knowledge circulation for Japan’s photon science ecosystem. This version adds a formal abstract and strengthens the framing of the paper as a discussion of photon-science knowledge infrastructure. It clarifies that proposals, experiment logs, metadata, consultation records, failed trials, inconclusive results, intermediate states, degradation precursors, boundary conditions, analysis choices, and lessons learned are not merely administrative residues or unsuccessful outcomes. When handled under appropriate confidentiality, disclosure, permission, and access-control conditions, they can form part of the reusable knowledge base needed for future user support, expert judgment, AI-assisted navigation, and scientific discovery. Version 1.6 also clarifies the meaning of scientific intuition in the paper. Scientific intuition is treated not as an ungrounded feeling, but as experience-based immediate judgment formed through repeated exposure to experiments, anomalies, failures, partial successes, boundary conditions, and expert interpretation. The proposed knowledge infrastructure is therefore intended not to automate intuition itself, but to make its experiential basis more visible, reusable, and accountable where appropriate. The update further refines the treatment of automation and AI. It recognizes the growing importance of automated sample exchange, remote operation, AI-guided scanning, active learning, and closed-loop experimentation in advanced photon-science facilities. At the same time, it distinguishes the present paper’s use of AI agents from fully autonomous experimental steering. Here, AI agents and the AI concierge are first understood as human-supervised tools for recording, structuring, retrieving, and handing off experimental judgment. They do not replace researchers, beamline scientists, safety reviewers, peer review, beamtime allocation, or institutional decision-making. Version 1.6 makes the near-term implementation boundary more explicit. The initial implementation should be limited, low-risk, and reviewable: public-information-based RAG guidance, FAQ support, beamline and method navigation, and preparation of consultation packages for human experts. More sensitive uses involving internal operational knowledge, experiment logs, sample-environment conditions, safety constraints, proprietary information, or interpretive conclusions should be introduced only gradually, under explicit governance, access control, source traceability, and human accountability. This version also adds a clearer intergenerational motivation. SPring-8-II is described as a renewal opportunity that occurs only once in approximately thirty years. The paper therefore asks what should be recorded for those who will design the next renewal after SPring-8-II: not only technical specifications, but also the reasoning behind design choices, what was prioritized, what was sacrificed, and what knowledge was already felt to be disappearing. Version 1.6 includes the English version of the discussion paper and, where uploaded with this record, accompanying reference and communication materials such as the Japanese machine translation and explanatory slide PDFs in English and Japanese. These Japanese materials are provided to improve accessibility for Japanese readers and to support domestic discussion. In case of any ambiguity or discrepancy, the English version should be regarded as authoritative. This document is an author-prepared strategic discussion paper for international dialogue.
