无限的源观测 ID 会将 4062 个节点的图扩大到 192 MB;每次遍历都会释放工作线程,并随之使 /search 服务停止运行。

Corroborates #1124 / #1168 / #1360 / #1238 / #825 from a corpus that isolates one variable that the earlier reports could not: our graph is logically tiny and still fatal.

Previous reports hit this at 9,474 nodes (#1124) and ~75K nodes (#825), so "large graph" was a plausible confound. Ours is 4,062 nodes / 7,357 edges — an order of magnitude smaller than #825 — and the worker still dies on every traversal. The failure tracks bytes per record, not graph size.
