CHEX: Multiversion Replay with Ordered Checkpoints

Summary: Defines multiversion replay for containerized workflows; uses system-call lineage to decide safe state reuse. CHEX uses ordered checkpoints, in-memory cache, and NP-hardness-aware heuristics to cut replay time by ~50% with lightweight sharing. (summarized by gpt-5-nano on Feb 09 2026)
