- Fixed: a delivered peer body now survives a tool-calling turn. The body was spliced into the first provider request only; OMP rebuilds every continuation request from its own store, where the delivery is just the `<msg from="peer"/>` stub, so an agent that called a tool before replying composed its answer from a context in which the message was empty and reported "your message arrived empty". Delivered bodies are now remembered per delivery signature and re-spliced (idempotently, bounded by count and bytes) into every later boundary that still shows their stub. This is the root cause behind the field ">400B bodies arrive empty" reports: size was a proxy for tool use, not the trigger (KNOWN-HAZARDS #10, `REQ-HAZARD-DELIVERY-BODY-DURABILITY`).
