+# FireWorldBench-new
+
+筛选后的 I 轨试做集，共 50 道逻辑题（选择题和开放题成对）。同事件、同题型的 S 轨文本题一并附上，共 145 个 S 逻辑题。问题行 390。有结构的二维场 133 张图；没有结构的场 62 处不附图，只在 `material` 里给出原切片按 R1–R8 算出的一个统计量。
+
+三维图沿用原图。题干文字、选项和 Gold 不改。
+
+## 数据入口

+- `main_synthetic/full_test_A/questions.jsonl`
+- `main_synthetic/full_test_A/gold.jsonl`
+- `main_synthetic/assets/i50/`：有结构的新图
+- 没有结构的场：`material` 中无 `path`，含 `statistic` 和 `regions`
+
+区域：沿 x 从入口到出口均分 8 段，R1 为入口。温度和第 95 百分位、烟炱第 95 百分位、能见度第 10 百分位、速度第 90 百分位、纵向/竖向速度为平均值。图的底色是略浅于旧图的海军蓝，等高线 1.2 pt。
+
+尚未做关键区域裁剪。评测尚未在这 50 题上重跑。

Derive the complete profile from the raw observations; no calibrated score, winner, runner-up, stability label, or switch label is supplied in this item. For this short-answer item, predict only: risk_region, risk_level, risk_driver, runner_up_region, stability_phase, winner_switch_count_bin.  Return one JSON report with free-language conclusion, prediction, evidence, mechanism, and confidence. The prediction object must contain only the requested field or fields.", "answer_fields": ["risk_region", "risk_level", "risk_driver", "runner_up_region", "stability_phase", "winner_switch_count_bin"], "physical_axis": "P3", "fire_axis": "T2"}

Observation positions map to early, middle, and late. The sequence may contain one synthetically injected cross-time or cross-signal anomaly, so compare every observation with the preceding state instead of assuming smooth-looking readings are consistent. A consistent sequence uses first_violation_bin=none and violation_type=none; otherwise classify the first injected discontinuity as jump, disappearance, direction_flip, or sensor_conflict. For this short-answer item, predict only: consistency, first_violation_bin, violation_type.  Return one JSON report with free-language conclusion, prediction, evidence, mechanism, and confidence. The prediction object must contain only the requested field or fields.", "answer_fields": ["consistency", "first_violation_bin", "violation_type"], "physical_axis": "P4", "fire_axis": "T1"}

For example, when forecasting from T=30, a crossing at T=45 is 30_60s, not 10_30s. Use none for all three fields if no future crossing occurs. For this short-answer item, predict only: trigger_variable, region, time_bin.  Return one JSON report with free-language conclusion, prediction, evidence, mechanism, and confidence. The prediction object must contain only the requested field or fields.", "answer_fields": ["trigger_variable", "region", "time_bin"], "physical_axis": "P1", "fire_axis": "T3"}

bin, and trigger variable. Time bins use absolute simulation time, never elapsed forecast time: 0_10s means T<=10, 10_30s means 10<T<=30, 30_60s means 30<T<=60, and after_60s means T>60. For example, when forecasting from T=30, a crossing at T=45 is 30_60s, not 10_30s. Use none for all three fields if no future crossing occurs. For this short-answer item, predict only: region, time_bin.  Return one JSON report with free-language conclusion, prediction, evidence, mechanism, and confidence. The prediction object must contain only the requested field or fields.", "answer_fields": ["region", "time_bin"], "physical_axis": "P1", "fire_axis": "T3"}

bin, and trigger variable. Time bins use absolute simulation time, never elapsed forecast time: 0_10s means T<=10, 10_30s means 10<T<=30, 30_60s means 30<T<=60, and after_60s means T>60. For example, when forecasting from T=30, a crossing at T=45 is 30_60s, not 10_30s. Use none for all three fields if no future crossing occurs. For this short-answer item, predict only: region, time_bin.  Return one JSON report with free-language conclusion, prediction, evidence, mechanism, and confidence. The prediction object must contain only the requested field or fields.", "answer_fields": ["region", "time_bin"], "physical_axis": "P1", "fire_axis": "T3"}

The sequence may contain one synthetically injected cross-time or cross-signal anomaly, so compare every observation with the preceding state instead of assuming smooth-looking readings are consistent. A consistent sequence uses first_violation_bin=none and violation_type=none; otherwise classify the first injected discontinuity as jump, disappearance, direction_flip, or sensor_conflict. For this short-answer item, predict only: consistency, first_violation_bin, violation_type.  Return one JSON report with free-language conclusion, prediction, evidence, mechanism, and confidence. The prediction object must contain only the requested field or fields.", "answer_fields": ["consistency", "first_violation_bin", "violation_type"], "physical_axis": "P4", "fire_axis": "T1"}
