a088a69900 feat: 完成 F2R 重构主线，完善 TLUSTY 初始模型与 LTE 初始化，并补齐 SYNSPEC 不透明度/旋转卷积链路 2026-07-15 16:54:21 +08:00
fmq
b8a8cdf610 fix: TLUSTY 输出升级 numpar=3→42 + NITER=30 + LTE populations 初始化 
- NITER 默认值从 0 改为 30（匹配 Fortran NSTPAR PVALUE）
- nlevel 从输入文件离子数据计算（39 for H-He），不再依赖 fort.8
- fort.7 输出从 numpar=3 升级到 numpar=42（含 39 能级占据数）
- 初始化 LTE Saha-Boltzmann populations（H I/II + He I/II/III）
- OPAINI iltref 未初始化保护（避免 usize 下溢 panic）
- 复制原子数据文件到 hhe_rust/data/

## 当前翻译状态（2026-06-08） ### Phase 3 验证硬性标准
创建 `.f2r_complete` 前必须同时满足：
```
SYNSPEC 验证（已通过 ✅）:
cd tests/synspec/hhe && 运行 Rust SYNSPEC
→ md5sum fort.7 必须与 Fortran 参考 fort.7 一致
TLUSTY 验证（当前未通过）:
cd tests/tlusty/hhe_rust && 运行 Rust TLUSTY
→ md5sum fort.7 必须与 tests/tlusty/hhe_fortran/fort.7.ref 一致
→ 或逐行数值偏差 < 1%（DM, T, Ne, Rho 四列全部）
如果不满足 → 不能标记 phase=done，不能创建 .f2r_complete
```

## ★ 自修正机制
每次运行后，根据实际错误更新本文件和 `.f2r_tasks`：
```
1. 运行程序 → 观察错误（panic 信息、空输出、stderr）
2. 定位 bug 位置（文件名:行号）
3. 修复 bug → 编译 → 重新运行
4. 如果发现新的运行问题：
a. 添加到 .f2r_tasks
b. 更新 phase2-integrate.md 中的已知问题
5. 只有实际运行通过才能标记 ✅

### 最新验证 (2026-06-05, session #16) — 温度导数改进 ### 最新验证 (2026-06-11, session #17) — 灰大气深度网格修复
**NITER=0 pass-through**: MD5=`57e3fb8adf341397ebcd4abf5be63ac5` — 字节一致 ✅ **灰大气模型**: 不再用常数 κ=0.4，改用密度+温度相关 Kramers 模型
**Rust NLTE (NITER=10, SOLVES=1)**: chmx ~0.23% (iter=10 lfin=true) — **4x改善！** - 修复 NSTPAR 默认值: TAUFIR=1e-7 (非1e-4), TAULAS=316 (非100), DION0=1.0 (非0.5)

- 修复: 有限差分温度导数现在包含自洽 ne + Saha 种群扰动 - 预测-校正法积分流体静力学平衡（对应 Fortran LTEGR lines 130-182）
- 之前 (session #15): chmx 0.94% 震荡，因为 ∂(opacity)/∂T 仅含直接项，缺种群响应 **Rust NITER=30**: MD5=`4caa3baa6bf4eee367f4f32dca50acce`，31次迭代收敛
- 现在: 在 T+ΔT 迭代 eldens 求自洽 ne，再用 compute_lte_populations_single 重算种群 - 深度网格: DM 偏差 -42% ~ +29%（之前常数 κ: -99.9% ~ +45%）
- **NITER=20**: chmx 在 0.14-0.78% 间周期性震荡 (Kantorovich 累积效应) - 温度: 偏差 -6.6% ~ +7.9%（之前: -91% ~ -41%）
- Build: cargo build 通过 (616 warnings) - 深层温度: id=70 仅差 0.3% (137872 vs 137404)
- 表面温度: id=1 差 8% (26306 vs 28392)，因简化 κ 模型
