Seeds: victory T126 / max_turns T300 / max_turns T300. Same result as batch 3 — ttv-dev's cumulative tuning (BASE_CITY_HP 300, HEAL_PER_TURN 26, melee_fraction 0.40) creates stalemates. Batch 2 was the best (12/14) at earlier values. p1-defense-dev's garrison fix is good but buried by overaggressive siege dampening. Seed 1 T126 victory = +51 from batch 3's T75 (improvement) but still below 200 target. Seeds 2+3 can't CAPTURE at all. Action: revert ttv-dev HP+heal+melee to batch-2 values (260/20/0.50), keep garrison fix + wall penalties. 2026-04-16 12:40 BATCH 5 (p1-defense-dev garrison + ttv-dev 280/23/0.40): 12 PASS / 2 FAIL.

Batch 2 had victories 2/3 at original values.

Median TTV 300 (target ≥200 MET). Victory rate 1/3 33% (below 50-80% target) due to seed 1 T77 fast capture — AI-side failure: p1 builds 3 warriors vs p0's 9, never builds walls. ~30 LOC total Rust diff. Further seed 1 extension requires AI-side fix (p1 wall priority + mil scaling). Next task: AI build-priority adjustment.
