Builder::deterministic_external_spawn(bool)to thecurrent_threadruntime. When enabled,Handle::spawnfrom outside the runtime thread (e.g. fromspawn_blockingwork) drains the inject queue into the local queue at a fixed point each tick instead of interleaving — making the resulting schedule deterministic under paused time.39-line patch on top of v1.49.0+anthropic.1.
