+### Invariant companion
+
+The optional `@deepseek-ai/dsh-agent-loop/invariant` companion registers request reconstruction with `ctx.invariants`. The loop marks each request with an internal non-enumerable identity before freezing it; the companion then requires a live session and independently rebuilds the message boundary and folded request header from the log. Direct one-shot calls remain outside this contract even when callers freeze them or attach a session id.
