| ## 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 |
