 **Decision**: Lever-3 alone cannot close both gates simultaneously at ratio 2×. Lever-4 (occupation penalty) is being added on top rather than replacing lever-3 — the combination may reach equilibrium where games are long enough for high-tier development but short enough for decisive winners.

+**Lever 4 — occupation penalty** (IMPLEMENTED, batch run 2026-05-03):
 - `mc-city/src/city.rs`: added `captured_turn: Option<u32>` field, `mark_captured(turn)`, `occupation_production_mult(turn) → f64` (0.5 for 5 turns post-capture, 1.0 otherwise)
 - `api-gdext/src/lib.rs`: exposed `mark_captured(i64)` + `get_occupation_production_mult(i64)` on `GdCity`
 - `combat_utils.gd::capture_city`: calls `city._bridge._gd_city.call("mark_captured", GameState.turn_number)`
 - `turn_processor.gd::_process_production`: multiplies prod by `get_occupation_production_mult(turn_number)` per city
 - All 70 mc-city tests + 88 mc-combat tests pass

+**Diagnosis (combat-dev verdict 2026-05-03):** Lever-4's occupation production penalty restored decisive winners (10/10 victories) and high `winner_tier_peak` (4.0 median, matching R10) without resurrecting lever-3-alone's combat overshoot. **HOWEVER**, the new failure mode is more uniform: every game has p0 dominant + p1 stuck at tier 1. Lever-3+4 doesn't equalize the players — it makes the loser even less competitive. The alive-aware tier_peak_gap metric is undefined because no game has both players developed past tp≥2. This is **structurally worse** than R10's "uneven gap" mode (where at least both players developed).
+
+The capture/development tempo isn't fixed by stack-of-doom damage clamping + occupation penalty. The remaining levers (Round 2: turn-floor in `mc-turn::victory.rs::check_domination`; Round 3: tech-tree shortening in `game-data`) require cross-team handoff per the original objective scope.

+## Acceptance (2026-05-03 update)
+
+- ❌ tier_peak_gap (alive-aware) ≤4 median — N/A this batch (all games have p1_tp=1)
+- ✓ peak_unit_tier ≥3 in ≥7/10 absolute (10/10 in this batch; cite: `~/.cache/mc-src-20260502_215856/.local/batches/autoplay_batch/game_20260503_024038_*/turn_stats.jsonl`)
+- ❌ Median game-end turn — 284 this batch (within target ~T300, but 4 of 10 ended T100-150 via early domination)
+- ❌ Cross-team handoff to combat-dev/game-data for capture/balance work
+- ❌ p0-01 evidence updated to cite this objective's closure
+- ❌ Per-difficulty `AI_DIFFICULTY=hard|insane|easy` validation (not run this cycle)
+
+`status: partial` — lever-3+4 closes victory rate + winner_tier_peak gates but the alive-aware gap metric is undefined (loser never develops). 4 of 6 acceptance bullets remain ❌; cross-team handoff still required.
