Progress Sharing And State Visibility

via “progress-sharing-and-state-visibility”

Unique: Implements progress sharing as a structured, queryable execution trace rather than unstructured logging, enabling both real-time streaming and historical analysis of agent behavior

vs others: Differs from LangChain's callback system which is primarily for logging; Portia's progress sharing is designed for external consumption and integration with monitoring/UI systems, not just internal instrumentation
