# `reporters/tree` Source: [`src/reporters/tree.ts`](https://github.com/AI-for-dev/combo/blob/main/src/reporters/tree.ts) A run as a tree: a delegated subagent drawn under the one that asked for it. ## `treeOrder` *function* ```typescript export function treeOrder(subagents: readonly SubagentSnapshot[]): SubagentSnapshot[] { /* … */ } ``` Launch order, rearranged so that a child follows the parent it hangs under. The snapshot itself stays flat, and this is why: every existing reader keeps working, and the one that wants a tree asks for it here. A delegating run spawns its children after their parent anyway, so with a single root the order barely moves; with two parents working at once it stops interleaving three readers of one explorer with three of the other. **Nothing is ever dropped.** A subagent whose parent is not in the list - a reporter attached mid-run, a snapshot assembled by hand - is placed as a root, and anything the walk could not reach is appended rather than lost. A measurement that silently omits a subagent is worse than one that misplaces it. How deep each one is drawn is its own `depth`, decided when it spawned.
