`PauseType` (amber/src/main/scala/org/apache/texera/amber/engine/architecture/worker/PauseType.scala) is a small sealed trait with three singleton pause kinds (`UserPause`, `BackpressurePause`, `OperatorLogicPause`) and one case-class subtype `ECMPause(id: EmbeddedControlMessageIdentity)` used by the worker pause subsystem. It has no test coverage today. Add a `PauseTypeSpec` that pins: - The three pause singletons all extend `PauseType`, are object-identity stable, and compare unequal to each other (widened to `PauseType` to defeat compile-time constant folding). - `ECMPause` carries the id it was constructed with, supports case-class value equality + hashCode, and is distinct from every singleton PauseType. - Exhaustive `match` over `PauseType` distinguishes each subtype, and ECMPause's id destructures via match. -- This is an automated message from the Apache Git Service.
