Three orchestrator failures traced through the Sep 7 gpt-6-astra campaign sessions: 1. delegation.independent_completions (new, default false). #104299 made every ungrouped task its own completion message, so a 15-task call woke the orchestrator up to 15 times; one chain received 132 notices and answered 130 of them with "already incorporated". A multi-task call now returns as ONE consolidated message unless the flag is on; `group` is inert until then. 2. Queued units were killed before they started. Units of one call share a pool slot but the executor was still sized by slots, so with 15 units live a new unit queued behind a full pool; the stale monitor's clock ran from dispatch, interrupted it at 450 s, and the child exited `interrupted 0.02s` when its thread finally came up (13 such lanes in one session). The executor now grows to the number of live units and the stall clock arms when the runner actually starts. 3. The tool text said "do not wait or poll — just continue" without saying that completions are delivered only BETWEEN turns. A model that never ends its turn (one 203-minute turn, 717 API calls) never received 40 finished results. Tool description, dispatch note and completion header now say to finish independent work, give a one-line status, and end the turn.
