Search the open indexes for Fusion and Frontier Energy; software is cited by its SWHID from Software Heritage, and a quantified scenario run is preregistered on OSF before it is run. Annotation is your choice: Hypothesis opens this page in its own viewer.
Mirrors and harvest
The DOI is canonical. At release each signed bundle is also given an IPFS content identifier and a bloxberg anchor as mirrors; both are listed in the record once they exist. Zenodo exposes every record over OAI-PMH, and reviews and endorsements can arrive through COAR Notify where the repository supports it.

}C.5Where this edition sits among the six pillars
Foundry seals the evidence and Universe tests it; Reports publishes it; Standards takes its corrections and Academy teaches from it.
- F03 Sealed observations and indicator series Foundry Sealed observations and indicator series behind a profile (closeout).
- F04 After-action and scenario findings for Universe After-action and scenario findings for chapters 10 and 13 (after action review).
- F05 National Portfolio movement for chapter Foundry National Portfolio movement for chapter 11 (after action review).
- Applied in editions Standards Nexus Standards: applied in editions.
- XT-14 edition Reports Fusion and Frontier Energy 2026, published in every format with its sources, citation and corrections.
- F06 Method and correction findings as change Standards Method and correction findings as change proposals (correction).
- F12 Q4 synthesis informs the next-year Universe Q4 synthesis informs the next-year mandate (renewal).
- Taught in the open Academy Risk Academy: taught in the open.
What Foundry and Universe hand to this edition, and what it hands to Standards, Universe and Academy. From the programme spine; XT-14 is a drafted Baseline Edition, so these handoffs run from its first operational quarter.
