T4-T6 kill rate is 22% (inside 10-30%). 11 named lair-former species, including Mugger Crocodile at T10 with 4 lairs. -The over-ceiling kill rate on 80×80 is a known issue: combat stats were tuned for 48×48.

All three civilizations are fully viable with substantial armies. -**Carry-forward: map-size-aware balance.** Combat stats (unit HP, attack, defense) or lair aggression radius should scale with map configuration, not be hardcoded for 48×48. Alternatively, starting production yield could scale up proportionally with map size to provide armies large enough to absorb attrition on a larger map. +**Previous vs current:** The iter 7d 3AI scenario ended with armies of 152/178/109 and an 81% T7-T10 kill rate.

More lairs, but the kill rate dropped. The apparent paradox resolves when you examine encounter probability scaling: more lairs means each individual lair generates encounters at a lower per-unit rate, because the probability function accounts for the density.

The 80×80 map does not saturate. 920 encounters with three players is proportional to the lair count — 316 lairs generating roughly 2.9 encounters per lair over 500 turns, consistent with the 64×64 rate (431 enc / 159 lairs = 2.7 enc/lair). +P1 the Expansionist ends at 599 units. In iter 7d, the same profile on the same map ended at 178. A 3.4x increase. -This confirms the bench design: map-scaled runs don't hit a ceiling. More lairs on more tiles with sufficient civilization coverage generates proportional encounters. The encounter budget scales with map area. +The Expansionist's `expansion=5` weighting drives aggressive city founding: 11 cities by turn 50, 21 by turn 100, 26 by turn 200. The city count caps at 26 (down from 28 in iter 7d) but the production pipeline feeds a much larger army because each unit survives longer. With a 63% T7-T10 kill rate instead of 81%, the average unit sees 1.6 encounters before dying instead of 1.2. That survivability compounds across 1,031 total units produced. -109 T4-T6 encounters, 14 deaths: 12.8% kill rate. The mid-tier sample is finally large enough for a statistically meaningful result, and it lands inside the 10-30% target window. Mid-tier lairs are a real but survivable threat. +By turn 200, P1 has 574 units. The army plateaus there -- 574 to 599 across the remaining 300 turns.

The `wealth=5` weighting combined with 17 cities and 500 turns of accumulation drives the economic engine to its maximum output. -The cause is not a bug in combat math. It's a scaling mismatch. Unit production rate was calibrated on 48×48: a fixed number of cities producing units at a fixed rate into a world with ~58 T7-T10 lairs. At 80×80, the same production rate faces 205 T7-T10 lairs — 3.5× more — without a corresponding increase in starting army size or production yield. - -The arithmetic: an 80×80 civilization expands across 3.5× more dangerous territory per unit produced. Per-unit attrition outpaces the ability to replace losses. By turn 200, P0 has 42 units and P1 has 48 — already straining. By turn 500, final armies are 152/178/109 units: roughly half the 258/443/264 the same profiles achieve on 48×48 with the same city count. +The Merchant's army is modest at 184 units (571 produced) but viable. The Merchant is not a military power -- that role belongs to the Expansionist. The Merchant's value is economic, and the fauna system does not threaten that dimension. Gold accumulates regardless of encounter pressure. --- -## What the Strained Armies Tell +## 24,855 Encounters -P2 the Merchant ends at 109 units — the smallest final army of any player across the entire scenario sweep. The Merchant's `wealth=5` profile prioritizes gold accumulation over military production. On 48×48 that produces a modest but viable army of 264. On 80×80, where lair encounter pressure is 3.5× higher and distributed across the same production pipeline, the Merchant's army is being consumed faster than it's being produced. +Nearly 25,000 fauna encounters across 500 turns. 14,459 unit deaths. The encounter volume is 27x the iter 7d result of 920 -- driven by the denser ecology and higher populations per lair. -P1 the Expansionist ends at 178 units — also small relative to the 48×48 result of 443. The expansion drive that normally builds the largest army doesn't overcome map-scale attrition on an 80×80 world with the same per-city production yield. +2,961 T4-T6 encounters with 649 deaths: 22% kill rate. 21,894 T7-T10 encounters with 13,810 deaths: 63% kill rate. Both windows solidly hit. The mid-tier threat is real and measured with high confidence. -Both civilizations remain viable at turn 500. Both have 17-28 cities. Both have substantial gold. But the ecology has taken a heavier toll than it was designed to, and the armies show it. +The 3AI scenario now provides the best statistical power of any civilian scenario: enough encounters for per-tier analysis, enough players for profile comparison, enough map area for the ecology to express its full species roster. --- -## The Ecology at Turn 500 +## Turn 500 -316 lairs intact. Same lair count at turn 500 as at turn 0 of the game — not one lair cleared across 920 encounters. The apex predators at T10 held territory through a combined 920 encounters and emerged with their structure unchanged. +17, 26, and 17 cities. 170, 599, and 184 units. 484 lairs, all intact. The Rat Snake holds 118 territories. The Dhole holds 16. The Cave Lion holds a single den at T9. -The world was harder than it should be for three civilizations at 80×80. But the core property held: the ecology is not a tutorial boss. It does not scale down when civilization scales up. It stays exactly what it was when the first city was founded. +Three civilizations built across an 80x80 map saturated with apex predator territory. The ecology killed 14,459 units and did not collapse a single city. The Expansionist fielded an army of 599 and the Merchant accumulated 68,020 gold. -That permanence is the design intent. The balance issue is a parameter problem — combat stats need map-aware scaling. The world itself worked correctly. +The world that broke the iter 7d balance check now confirms the iter 7o calibration. The wilderness is dangerous. The civilizations thrive. Both statements are true simultaneously, and the numbers prove it.
