## Code Mode child-call tree
Every `ToolCallBlock` recursively owns its children through `subCalls`, in start order. Runtime's `ToolCallTree` privately maintains the parent-callId-to-children index: a `tool/code-dispatch-start` event lands as a `RunningToolCall`, and the matching `tool/code-dispatch` settlement replaces it in place with a `ToolResultNode` whose `callTime` comes from the paired start. When the start fell outside the replay window, the settlement appends directly with `callTime: null`; Runtime never fabricates a zero duration. Live mux frames and history replay share this fold and tree projection, and child calls never become independent roots in transcript `nodes`. A child update copies only its ancestor path to the owning root; unchanged siblings and other roots retain object identity.

Wire or history edges that would introduce a cycle or exceed the fixed 256-call recursive-depth safety limit are consumed without mutating the tree, so the rest of the session remains renderable.
