Under a loaded full-project run the serial prepare of 6 instances with a 300 ms reconcile deadline took 2.6 s and tripped the fixed 2 s cap (5/10 full runs failed under CPU load). Deadline raised to 2 s so it cannot expire before the query is sent; the elapsed bound is now derived from the deadline (must beat (n-1) deadlines) while the one-query assertion proves the breaker.
