Seeds 1/2/3: victory T75 / max_turns T300 / max_turns T300. Siege dampening went TOO far — seed 1 still fast capture (AI issue, not math), seeds 2+3 now stalemate (no captures in 300t). FAIL: victories 1/3 (33%, need 50-80%), median TTV 75, both-p5m4-T100 1/3. Root cause per ttv-dev: p1 garrison dies T69, doesn't rebuild. That's AI not combat.
