Overview

A link in the chain (stage 4). A Middleware MODIFIES the TurnState, short-circuits, and has operational effect (rate limit, tracing, cost) — it does NOT decide tool/skill permission (that is Policy). Short-circuit = NOT calling nxt and setting state.halt_reason. Setting halt_reason AND calling nxt is a contract violation (the Executor prioritizes halt_reason on the way back).

Concurrency: it runs on the task's fiber; IO (e.g. a tracing exporter) must be async off the path (Async { ... } fire-and-forget) or accept the latency in the turn. No timeout of its own (covered by the turn timeout).
