Messages use typed blocks from merge-extensible `ContentBlockMap`; the pattern also types `MessageSource`, `FinishReason`, `TurnTrigger`, and `TurnEndReason`. New blocks coordinate adapters, UI, compaction, token metering, and persistence; replay measurements live in [token-meter.md](core-data-structures/token-meter.md).
Streaming uses raw chunks and `BlockAssembler`. After final-stream construction, the loop emits contained, non-durable, non-replayed `agent/model-request` metadata. Adapters normalize failures; `agent/request-error` may retry. Remote adapters use per-read idle watchdogs. Replay crosses routes only through a shared adapter ([contract](core-data-structures/llm-streaming.md)).
Streaming uses chunks and `BlockAssembler`. When the outer `llm/stream` returns a handle, AgentLoop emits contained, non-durable, non-replayed `agent/model-request` attempt metadata—not proof of provider I/O. `agent/request-error` may retry.
