Two-Phase Commit
A distributed transaction protocol that coordinates multiple participants through a prepare phase and a commit phase, ensuring the atomicity of distributed transactions.

Workarounds for the tool-call side-effect problem include: executing candidates in a sandbox or transaction and committing after confirmation, or abstracting side-effecting actions into rollback-capable two-phase operations.
The two-phase dry-run validation borrows the idea of two-phase commit (2PC) from the database field; the first phase is the simulation phase that validates permissions and dependencies, and the second phase is the commit phase that performs the actual state changes
分布式系统中部分失败的解决模式包括两阶段提交（2PC）、Saga模式和事件溯源（Event Sourcing）
两阶段提交保证强一致但牺牲可用性，Saga模式通过补偿事务实现最终一致
