The drill spawner measured its best-of-9 lane spacing only against bodies still in the back half (drillNearZ 9 m). On a court where lanes are HELD for life and speed is stamped at spawn, a body 12 m down still owns its lane — handing it to a faster arrival books an overtake for ten seconds later, mid-court, as two sprites walking through each other. That is what the seed-sensitive test failure (SEED=1234) was reporting: the assertion was right, the stream was not. Spacing now measures against every live drill body; drillNearZ is deleted (no other reader). Still best-of-9, no retry loop, so the stream cannot stall. 60 seeds x 150 s of drill: before, 7 seeds overlapped with narrowest clearance 0.00 m; after, zero overlap frames, narrowest 0.46 m (the test asks > 0.3). Suite green on 20260811/1234/777/99/424242/8 and on 299 of seeds 1..300; the straggler (SEED=80, the slid-serve return rate) is unrelated and logged as open.
