Token Transactions: Managing Fine-Grained Migration of Data

Summary: Treats per-site cache access rights as fragments of a global token database and migration as token transactions, enabling fine-grained data movement to transaction initiators. Presents Unilateral Commit Protocol (UCP) to recover token ownership and enforce token-state consistency after failures, with correctness shown versus 2PC. (summarized by gpt-5-mini on Feb 09 2026)
