The Cost and Network Limits of Space-Based AI Compute

This feed contains multiple distributed-systems and infra papers with several security-relevant findings. Key issues: (1) a practical memory-exhaustion (DoS) attack against the blocklace CRDT that can force correct nodes to replicate arbitrarily many useless updates unless identifier-acceptance is restricted; (2) measured enforcement gaps in six popular open-source LLM-agent frameworks where pre-execution approval/cancellation/timeouts fail to prevent sibling branches or replayed side effects — the authors demonstrate real-world reachability and provide SOUNDGATE, a kernel-routed Rust gate, as
