Task Summary
LoopIntegrationSpec (added in #5700) is now the most expensive suite in the amber-integration CI job. Two cost drivers:
| Driver |
Cost |
| Nested cases run 3x3 iterations; every iteration respawns all region workers (~2s per Python worker) |
~2 min of the suite on ubuntu |
On macOS the suite intermittently hangs mid-run and burns the whole 3-minute deadline before withRetry re-runs the test |
~3-4 extra min per occurrence; observed in 3 of 4 attempts across two runs on 2026-07-29 |
Trim the nested cases to 2x2 (nesting depth, not per-level iteration count, is what exercises the counter/routing envelope) and tighten the deadline to 90s so a hang costs less. Root-causing the macOS hang itself is tracked separately.
