### Task Summary `Region` (`amber/src/main/scala/org/apache/texera/amber/engine/architecture/scheduling/Region.scala`) is the unit of execution for the workflow scheduler but currently has no dedicated unit tests. Add `RegionSpec` covering its public surface: - Constructor exposes `physicalOps`, `physicalLinks`, and `ports` via `getOperators`/`getLinks`/`getPorts` - `getOperator(id)` looks up by `PhysicalOpIdentity` and throws `NoSuchElementException` for unknown ids - `topologicalIterator` yields operators in topological order derived from `physicalLinks` - `getSourceOperators` treats operators without input ports as sources - `getStarterOperators` equals `getSourceOperators` when no `resourceConfig` is provided ### Priority P3 – Low ### Task Type - [x] Testing / QA -- This is an automated message from the Apache Git Service.
