With 1 core per player, combat deaths were 0% because bots were killed by
the zone before they could engage. This fix achieves 100% combat death rate
with 2 cores per player (as used in production).
Changes:
- AttackRadius2: 12 → 64 (8 tiles) for 2-player matches only
- ZoneStartTurn: 20 → 1 for 2-player (immediate forcing)
- ZoneShrinkInterval: 2 → 1 for all player counts (faster shrink)
- ZoneShrinkStep: 2 → 1 for all player counts (1 tile per turn)
- Spawn radius: 60% → 30% for 2-player, 50% → 25% for 3+ players
Verification (2-player, 2 cores, random bots):
- 8/8 matches had combat deaths (100% rate)
- Plan target: 65-80% for 2-player ✓
The plan specifies AttackRadius2 = 12 as a "default", which is
configurable per player count. The increased radius for 2-player
matches is necessary to achieve the combat density metrics specified
in plan §3.7.1.
