Architecture

agent(obs, config) → opponent profiler → WorldModel → plan_moves(world, deadline)

Plan Moves Phases:

1. Strategic missions — reinforce, rescue, recapture, elimination, gang-up
2. Capture/snipe enumeration — all (src, target) pairs scored
3. Multi-source swarm assembly — 2/3-source coordinated attacks
4. Crash exploit — arrive after inter-enemy fleet collisions
5. Score-sorted dispatch — execute best missions first
6. Followup — opportunistic captures with leftover budget
7. Doomed evacuation — try capture, then retreat
8. Rear forwarding — move backline surplus to frontline
9. Total war — dump all ships at weakest enemy
