 ## Purpose
 
 Instead of each component defining its own types, Commons centralizes:
-- Communication message types
-- Task definitions
+- Communication message types (including training progress, control signals)
+- Task definitions (JobType::Task, JobType::Training, JobType::DataPreparation)
+- Training job payloads (TrainingJob, InferenceJob, TrainingMetrics, TrainingControl)
 - Configuration structures
 - Storage schemas
