Module envelope 

The request/response envelope: the normalized LlmRequest/LlmResponse paired with the original provider payload and correlation Metadata.

Structs

Context

Cross-cutting request context passed through algorithms and LLM clients.

Request

A request an algorithm routes: the normalized LlmRequest plus optional host-owned raw data and correlation Metadata.

Response

A response an algorithm returns: the LlmResponse (streamed or aggregate) plus optional correlation Metadata.

Signals

Agentic-stack events fed to an algorithm out of band (e.g. tool results, budget updates) — in libsy, via Algorithm::process_signals.
