- **7:36 GPT-5.6 Terra**: Enemy infantry force is inside the base and the Construction Yard is critically damaged. Focus all current combat units on the nearby rocket soldiers while repairing key economy and construction structures; existing tank and rocket queues should provide the counterattack force shortly.
- **7:36 Claude Sonnet 5**: Enemy fact is at 12% hp - finish it off to win. Concentrate all frontline units on it.
- **7:44 GPT-5.6 Terra**: Enemy infantry and rockets are inside our base while our combat force has been wiped out. Keep both harvesters mining for emergency income, finish the queued rocket/tank production, and immediately add power as soon as funds arrive.

- **7:52 GPT-5.6 Terra**: The base is critically exposed to a large enemy infantry/rocket blob while power is low and both harvesters are damaged. I will restore power as soon as ore arrives, keep both trucks mining, and stop the excessive light-tank queue so vehicle production can react to the immediate threat.
- **7:52 Claude Sonnet 5**: Army near enemy base, finish off remaining buildings to secure win.
- **8:00 GPT-5.6 Terra**: Enemy infantry are inside the base while our only active production is six Light Tanks. Preserve the damaged harvester, rally all tanks toward the enemy start, and use the returning ore income to stabilize.

- **8:32 GPT-5.6 Terra**: We have no Construction Yard or active army, and the remaining refinery is critically exposed to enemy infantry. Preserve the last refinery while repairs continue; there is no viable production path until a Construction Yard is somehow recovered.
- **8:32 Claude Sonnet 5**: Army near enemy base at (95,10) but buildings not visible yet—likely destroyed or hidden further. Push all idle units to explore/attack around enemy start area. Keep production flowing.
- **8:40 GPT-5.6 Terra**: Our base has effectively collapsed: only one refinery remains, no construction yard or power, and the remaining harvester is a wreck. Sell the refinery to recover value and potentially gain a few infantry, then use any resulting units to engage the nearby enemy rifleman.
- **8:40 Claude Sonnet 5**: Enemy base near (95-97,8-13) seems mostly destroyed. Push remaining forces further east/north to find and destroy last buildings. Keep training more troops and maintain economy.
