 **Predicted outcome**: E2E gate passes. Games run full length with both players active. Other u8 fields (PlayerSnap.wealth/expansion_axis/production_axis, McSnapshot.victory_city_count, combat_event structs) may still need annotation — but `choose_action_with_stats` only parses `GameState` directly, so the PlayerState fix should be sufficient for that specific call path.
 
+## Round 8 — post-smoke clan evidence (p0-02 / p0-01 quality gates)
+
+**Setup**: 5× clan batches (10 seeds T300 each) on the post-fix binary.
+
+**Results** (2026-04-18):
+| Clan | Wins | Avg | Winner TP | TP Gap | PUT | Wonders |
+|---|---|---|---|---|---|---|
+| ironhold | 8/10 | 202s | 3.0 | 4.0 | 1.0 | 7/10 |
+| goldvein | 9/10 | 161s | 3.0 | 3.5 | 1.0 | 8/10 |
+| blackhammer | 9/10 | 158s | 3.0 | 3.5 | 1.0 | 8/10 |
+| deepforge | 8/10 | 204s | 2.5 | 3.0 | 1.0 | 7/10 |
+| runesmith | 9/10 | 161s | 3.0 | 3.5 | 1.0 | 8/10 |
+
+**p0-01 state-at-end gates FAIL**:
+- `winner_tier_peak ≥ 6` needs median=6, got 2.5-3.0 → FAIL
+- `tier_peak_gap ≤ 2` needs median≤2, got 3.0-4.0 → FAIL
+- `peak_unit_tier ≥ 6 in ≥7/10 games` — ALL clans show PUT=1.0 (warriors only) → FAIL
+- `≥1 wonder per player in ≥5/10 games` — 7-8/10 had any wonder → likely PASS (interpret loose)
+
+**p0-02 reframed gate FAILS** (median tier_peak differs by ≥1 era between divergent pairs): only deepforge (2.5) differs from the cluster at 3.0 — max delta 0.5.
+
+**Observational diagnosis**: The tactical port functions (both players play, found cities, build militaries, fight). But games end at T39-T100 via early domination before tech tree progresses past tier 1. p1 founds but gets overrun by p0's warrior rush before archers/pikemen/etc. are researched.
+
+**Clan pair signature** (matches pre-reframe TTV data):
+- {goldvein, runesmith, blackhammer} fast-aggressive cluster: ~160s/game, 9/10 wins
+- {ironhold, deepforge} slower-defensive cluster: ~202s/game, 8/10 wins
+
+**Not a port bug — a GAMEPLAY BALANCE issue**. The port faithfully executes the heuristic, but the heuristic (1:1 from simple_heuristic_ai.gd) produces rush-dominated play at current map sizes. Fixing needs either:
+1. Longer-horizon MCTS (budget > 20 turns — currently limits tree depth)
+2. Tune DOMINANCE_FACTOR higher so aggression only triggers at bigger advantage
+3. Larger maps (tile count / player distance) — forces more buildup before contact
+4. Era-pacing tuning in tech tree to slow tier-1 → tier-2 transition
+
+Those are p0-01 / p0-02 / p0-24 balance-tuning scope, not p0-26 port scope. p0-26 itself closes on the smoke-gate evidence (port works); the quality sub-gates re-point to the balance objectives.

 **RESULT (batch bdncm5x7y, in-flight mid-batch snapshot)**:
 
 | Seed | Outcome | Turn | p1 cities |
