What
Streamed tool events re-enqueued from a sub-agent now carry the parent tool use id from the event itself, so nested tool output is attributed to the right call.

the id on the event is preferred, with the enclosing tool use id only as a fallback
previously output from nested tool calls could be reattributed to the outer tool
Evidence
parentToolUseID
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
