Pull request overview
Updates the security model documentation to clarify a key limitation of TEEs and disk encryption: while dstack can protect confidentiality and measured execution, it cannot guarantee persistent storage freshness against an infrastructure operator who can roll back, replace, or withhold storage.
Changes:
- Documented that disk encryption does not prove “latest state” / freshness of attached persistent disks.
- Added explicit operator threat scenarios (withholding, deletion, replacement, rollback).
- Recommended anchoring monotonic state externally for rollback resistance.
💡 Add Copilot custom instructions for smarter, more guided reviews. Learn how to get started.
