   These five sub-gates jointly measure whether games feel like a competitive 4X arc regardless of victory mode. No single "median TTV" number replaces them — game length is a *consequence*, not a target.

+Normal-vs-Normal smoke (`apricot-20260418_074209`, 10 seeds T300, AI_GPU_ROLLOUT=false) + 5 clan batches (`apricot-20260418_08*` ironhold/goldvein/blackhammer/deepforge/runesmith):

+All 5 quality sub-gates FAIL: tier_peak 2.5-3.0 vs required ≥6, peak_unit_tier 1.0 vs required ≥6 in ≥7/10, tier_peak_gap 3-4 vs required ≤2, wonder_count 0 (none built), total_combats below target. **Diagnosis**: games resolve T39-T100 via early domination before tech progresses past tier 1. This is a GAMEPLAY BALANCE issue (domination threshold too loose, tech costs too steep, or map too small), not an AI defect — MCTS correctly pursues the shortest path to victory, which happens to be rush-domination under current data.

 **Remaining to reach done:**
-1. Land the `tier_peak` / `peak_unit_tier` / `wonder_count` instrumentation in `auto_play.gd` + `tools/autoplay-report.py` (tracked as p0-25).
-2. Run a Normal-vs-Normal 10-seed T300 batch with the new metrics exposed.
-3. If any sub-gate below target, tune MCTS rollout count, strategic axes, or difficulty.json pacing until all five hit. Tuning lives in warcouncil's lane.
+1. Tune one of: `DOMINANCE_FACTOR` (domination victory threshold), MCTS strategic horizon / rollout count, tech research costs, map size defaults, or difficulty.json pacing — until median `tier_peak` ≥ 6 in Normal-vs-Normal batch.
+2. Re-run Normal-vs-Normal 10-seed T300 batch; confirm all 5 sub-gates clear.
+3. Tuning lives in warcouncil's lane but parameter choice may require shipwright (economy/tech) input.

 - ✓ **Personality win-rate balance (blackhammer)**: FIXED 2026-04-17 via two GDScript-only changes: `DOMINANCE_GOLD_FLOOR` 200→50 (unblocks rush-buy for low-economy clans) and `PRODUCTION_AXIS_BUILDING_BIAS` 6→8 (raises threshold so aggression=9 clans prefer units over buildings). Batch `blackhammer_tune_20260417_101447` (10 seeds, T300, `AI_PIN_PERSONALITY=blackhammer`): **2/10 blackhammer wins** (seed 4 T71, seed 9 T125, both domination). Gate: ≥1 win in 10-seed sample — PASSED. Seed 8 hit safety timeout (892s, `in_progress`) — not a blackhammer loss. Prior B5 zero-win run (`.local/iter/b5-manual-20260417_061957/`) used old binary with DOMINANCE_GOLD_FLOOR=200.
 - 🟡 **Six axes each materially affect gameplay** — pre-reframe verification via per-axis ablation sweep (2026-04-17, `.local/iter/ablate_<axis>_20260417_072921/`): each axis neutralized to 5 for all clans; all 6 showed ≥10% delta on correlated legacy metric (aggression→mil -16.7%, expansion→TTV -27.6%, grudge_persistence→TTV -28.9%, production→TTV -24.9%, trade_willingness→gold -48.9%, wealth→gold -40.0%). Neutralizing any axis collapses domination win rate from 49/49 to 1–8/10 — games stall. **POST-REFRAME target**: re-run the 6-axis ablation under p0-25 instrumentation and pin the era-progression-axis correlations (expansion/production/grudge_persistence should each show ≥1 era delta on `tier_peak_med`; aggression/trade_willingness/wealth retain their existing mil_med / gold_med correlations). NEEDS re-run to cite under the reframed gate.

Root cause is the shared gameplay-balance issue tracked under `p0-01`: games resolve T39-T100 via rush domination before tech tree diverges. Once p0-01's pacing tune lands, re-measure divergence and close the remaining gate.

 ## Remaining to reach done
 
-Everything about axis wiring, per-clan weight resolution, the blackhammer balance fix, and the pre-reframe evidence (gold divergence, win balance, first-combat) STAYS shipped. The two remaining gates under the post-reframe framework:
-
-1. **Re-run the 5×10 clan batches on the p0-25-instrumented binary** (10 seeds each for ironhold/goldvein/blackhammer/deepforge/runesmith, T300). Cite median `winner_tier_peak` per clan and verify ≥1 era delta between production/expansion-divergent pairs. Estimate 25–40 min wall-time on apricot under the post-SIGTERM-cleanup environment.
-2. **Re-run the 6-axis ablation sweep on the p0-25-instrumented binary**. For era-correlated axes (expansion, production, grudge_persistence), replace the TTV delta with a `tier_peak_med` delta and verify ≥1 era drop when the axis is neutralized. For mil/gold-correlated axes (aggression/trade_willingness/wealth), the existing mil_med and gold_med deltas carry forward unchanged.
-
-Both batches can run in parallel. After they land, flip `status: done` and cite the new batch dirs.
+1. **Waiting on p0-01 balance tune** — era-divergence gate cannot be evaluated until games routinely reach tier 6+. After p0-01 lands its pacing fix, re-run the 5-clan batch and cite `tier_peak_med` delta between ironhold/deepforge (low production) and goldvein/runesmith (high production) pairs.
+2. **6-axis ablation re-run** on the tuned binary with `tier_peak_med` deltas for expansion/production/grudge_persistence. The pre-reframe ablation (2026-04-17) already confirmed all 6 axes live under the legacy metric; this is confirmation under the reframed gate.

-   `TreeState::rollout` serially per leaf. Needed:
