Two-phase commit's design-implementation gaps (known blocking window with no timeout enforcement, recovery requiring participant availability) are validated only under synchronous simulation where messages arrive instantly, meaning the real-world impact of coordinator crashes during the blocking window — where participants hold locks indefinitely — remains untested.
2PC's blocking window is characterized but only tested under instant delivery — actual timeout/crash behavior is unvalidated
