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

- 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/

+  CodeGraph 辅助 Fortran→Rust 重构。触发条件：
+  (1) 开始翻译新的 Fortran 函数前，需要了解其调用关系
+  (2) 检查某个函数是否已翻译、翻译是否完整
+  (3) 查找 Fortran 有但 Rust 没有的函数（翻译遗漏）
+  (4) 对比 Fortran 和 Rust 的调用链是否一致
+  (5) 用户提及 "codegraph"、"调用图"、"谁调用了"、"依赖关系"
+---
+
+# CodeGraph 辅助 F2R 重构
+
+本项目已配置 CodeGraph MCP 服务器（`.mcp.json`），Claude 启动时自动加载。
+不要进行全量测试，系统内存会被占满。
+
+## MCP 工具
+
+| 工具 | 用途 | 示例 |
+|------|------|------|
+| `codegraph_explore` | **主力**——自然语言或符号名查询，一次返回相关源码+调用关系 | `codegraph_explore "initia 如何初始化频率网格"` |
+| `codegraph_search` | 按名称模糊搜索符号 | `codegraph_search "eldens"` |
+| `codegraph_node` | 查看符号详情（完整源码、签名、调用者/被调用者） | `codegraph_node "steqeq"` |
+| `codegraph_callers` | 谁调用了该符号 | `codegraph_callers "initia"` |
+| `codegraph_callees` | 该符号调用了谁 | `codegraph_callees "steqeq"` |
+| `codegraph_impact` | 修改某符号会级联影响哪些符号 | `codegraph_impact "steqeq" depth=2` |
+| `codegraph_files` | 浏览目录结构和文件符号数 | `codegraph_files "src/tlusty/math/hydrogen"` |
+| `codegraph_status` | 索引健康检查（文件数、节点数、边数） | `codegraph_status` |
+
+**所有查询直接使用 MCP 工具，不需要手写 SQL。**
+
+## 命名约定
+
+### 函数命名：Fortran 与 Rust 完全对应
+
+所有 TLUSTY Fortran 函数在 Rust 中都有**同名小写**版本。
+
+```
+Fortran:  RECHECK   ACCEL2   INITIA   STEKEQ   ELDENS
+Rust:     rechck    accel2   initia   steqeq   eldens
+```
+
+### `_pure` 后缀（仅 9 个函数）
+
+| `_pure` 版本 | 非-pure 版本 | 关系 |
+|-------------|-------------|------|
+| `steqeq_pure` | `steqeq` | 纯计算内核 → 回调串联完整版本 |
+| `resolv_pure` | `resolv` | 纯线性化求解 → 28 子程序编排 |
+| `start_pure` | `start` | 纯启动计算 → 带 I/O 版本 |
+| `solve_pure` | `solve` | 纯矩阵求解 → 完整求解器 |
+| `inkul_pure` | `inkul` | 纯 Kurucz 谱线 → 带文件 I/O |
+| `lemini_pure` | `lemini` | 纯 Lemke 插值 → 带表查询 |
+| `radtot_pure` | `radtot` | 纯辐射通量 → 完整辐射传输 |
+| `rayini_pure` | `rayini` | 纯瑞利散射 → 带文件读取 |
+| `iroset_pure` | `iroset` | 纯铁族设置 → 带回调完整版本 |
+
+**规则**：`_pure` = 纯计算内核（可独立测试），非-pure = 完整编排包装器（匹配 Fortran 行为）。
+
+## 状态文件系统
+
+| 文件 | 用途 |
+|------|------|
+| `.f2r_phase` | 当前阶段：`translate` / `integrate` / `verify` / `done` |
+| `.f2r_tasks` | 当前阶段待办列表（每行一个，完成后加 ✅ 前缀） |
+| `.f2r_complete` | 存在 = 全部完成，脚本自动停止 |
+| `.f2r_rate_limit` | API 限流重置时间，脚本自动管理 |
+
+### 读取状态的规则
+
+1. 启动时读取 `.f2r_phase` 确定阶段
+2. 读取 `.f2r_tasks` 取第一个未完成任务
+3. 完成后在 `.f2r_tasks` 中该任务行首加 ✅
+4. 全部完成后更新 `.f2r_phase` 并生成新 tasks
+
+## 参考文档（按需查阅）
+
+| 阶段 | 文件 | 使用时机 |
+|------|------|---------|
+| Phase 1 翻译 | `references/phase1-translate.md` | 发现翻译遗漏时 |
+| Phase 3 验证 | `references/phase3-verify.md` | Phase 2 完成后 |
+
+---
+
+## 当前阶段：Phase 2 集成（integrate）
+
+**目标**：将已翻译的纯计算函数连接为可运行的编排流程。
+
+任务和工作流详见 `references/phase2-integrate.md`。
+
+---
+
+## 自动化模式（定时任务触发）
+
+定时任务 `scripts/specf2r.sh` 通过 `--print` 触发本 skill。
+触发后必须立即按以下流程执行。
+
+### 执行流程
+
+```
+Step 0: 读取状态
+  → 读取 .f2r_phase 确定阶段
+  → 读取 .f2r_tasks 取第一个未完成任务
+  → 没有未完成任务 → 更新阶段，生成新 tasks
+  → 没有更多阶段 → 创建 .f2r_complete
+
+Step 1: 检查索引（仅确认健康，不扫描）
+  → codegraph_status
+
+Step 2: 执行当前任务
+  → 分析目标函数/模块
+  → 实现修改
+  → 编译验证
+
+Step 3: 更新状态
+  → 标记任务完成 ✅
+  → 取下一个任务继续
+```

+
+> 状态：✅ 已完成（2026-06-06 ~ 2026-06-07）
+> TLUSTY 350 函数 + SYNSPEC 168 函数 = 518 函数全部翻译为 Rust
+
+此文件仅供参考。仅在发现翻译遗漏或需要翻译新函数时查阅。
+
+## 翻译流程
+
+### Step 0: 数据同步
+
+CodeGraph 索引路径：`/home/dckj/SpectraRust/.codegraph/`
+
+每次 Rust 代码修改后，MCP 文件监视器会自动同步（2秒延迟）。如有疑问可手动触发：
+
+```bash
+cd /home/dckj/SpectraRust
+node /home/dckj/program/codegraph/dist/bin/codegraph.js sync
+```
+
+如果添加了新目录或数据异常，重建索引：
+```bash
+rm -rf /home/dckj/SpectraRust/.codegraph
+cd /home/dckj/SpectraRust
+node /home/dckj/program/codegraph/dist/bin/codegraph.js init -i
+```
+
+### Step 1: 选择翻译目标
+
+使用 `fortran-analyzer` skill 获取优先模块。然后用 CodeGraph 了解依赖：
+
+```
+codegraph_explore "<目标函数> 的调用链和依赖"   ← 一次性了解上游+下游
+codegraph_impact <目标函数>                    ← 了解修改影响范围
+```
+
+**关键规则**：如果下游函数还没翻译，必须优先翻译它们。
+
+### Step 2: 翻译函数
+
+用 `codegraph_node <函数名>` 获取完整信息：
+- Fortran 源码（完整函数体）
+- 所在文件和行号
+- 签名、参数、返回值
+- 所有调用者和被调用者列表
+
+对照 Fortran 源码逐行翻译。翻译后的 Rust 函数直接使用 Fortran 同名小写，
+例如 `ELDENS` → `pub fn eldens(...)`。
+
+### Step 3: 验证调用链一致性
+
+翻译完成后对比 Fortran 和 Rust 的调用链：
+
+```
+codegraph_explore "<函数名> Fortran vs Rust 调用链对比"
+```
+
+两边的被调用者列表应该结构一致（Rust 端用 snake_case，Fortran 端用 UPPER_CASE）。
+如果 Rust 端缺少被调用者 → 可能需要创建非-pure 编排包装器。
+
+### Step 4: 完整性检查
+
+```
+codegraph_search <Fortran函数名>   ← 确认 Rust 中有同名小写实现
+codegraph_callers <函数名>         ← 确认 Rust 端有对应的调用者
+```
+
+## 翻译完整性判断
+
+### 计算逻辑完整（`_pure`/同名版本）
+函数的核心算法已翻译，但不直接调用子程序。占 TLUSTY 的绝大多数。
+
+### 编排完整（非-pure 包装器）
+函数不仅包含计算逻辑，还通过回调或直接调用来串联子程序，完整匹配 Fortran 行为。
+目前仅 9 个函数有此版本。
+
+### 判断标准
+
+```
+codegraph_callees <函数名>   ← Rust 端
+codegraph_callees <函数名>   ← Fortran 端（用大写名）
+```
+
+- 两边被调用者列表完全匹配 → **编排完整**
+- Rust 端缺少被调用者 → **计算逻辑完整，需编排包装器**
+- Rust 端没有该函数 → **未翻译**

+## 任务来源
+
+从 `.f2r_tasks` 读取。当前主要任务方向：
+
+### 1. TLUSTY RESOLV 编排补全 (`src/tlusty/io/resolv.rs`)
+
+Resolv 是 TLUSTY 主循环的核心编排器，每个频率点调用一次。当前有 7 个 TODO：
+
+| TODO 位置 | 内容 | 说明 |
+|-----------|------|------|
+| L81 | 原子数据丰度 | 从原子数据文件读取精确值替换硬编码 HHe 值 |
+| L2038 | ComputeArrays 传递 | 将 ComputeArrays 添加到 ResolvParams 或从调用方传入 |
+| L2146 | ComputeArrays 传入 | 同上，另一处调用点 |
+| L2251 | rru/rrd 累积 | 累积辐射率获得完整输出 |
+| L2439 | CoolrtParams 2D | 重构为 2D 接口获得精确冷却率 |
+| L2606 | 频率不透明度更新 | 按频率从 opacfl_data 更新不透明度 |
+| L2624 | rtecmu 频率循环 | 循环所有频率点调用 rtecmu+opacf1+taufr1 |
+
+### 2. TLUSTY Runner (`src/tlusty/main.rs`)
+
+| TODO 位置 | 内容 |
+|-----------|------|
+| L482 | 实现正确的 IJALI 频率选择（只用关键频率） |
+
+### 3. TLUSTY OPFRAC (`src/tlusty/math/continuum/opfrac.rs`)
+
+| TODO 位置 | 内容 |
+|-----------|------|
+| L309 | 解析 ioniz.dat 文件完整实现 |
+
+### 4. SYNSPEC Runner (`src/synspec/runner.rs`)
+
+连接所有编排步骤的参数传递，确保完整流程可运行：
+- CHANGE: 能级人口重分配
+- MOLINI: 分子平衡初始化
+- EOSPRI: EOS 参数诊断输出
+- ABNCHN: 丰度缩放
+- INGRID 网格模式完整流程
+- INMOLI 循环
+- IDMTAB 实际调用
+- FINGRD 最终输出
+
+### 5. SYNSPEC RESOLV (`src/synspec/math/resolv.rs`)
+
+- 构造完整的 ResolvParams 从模型数据
+- 填充 OPAC→RTE→OUTPRI 完整调用链
+
+## 集成工作流（严格遵守）
+
+```
+每次会话：
+1. 读取 .f2r_tasks → 取第一个未完成任务
+2. 读取任务对应的目标文件，定位 TODO
+3. 使用 codegraph 了解调用关系和依赖：
+   codegraph_explore "<目标函数> 的调用链"
+   codegraph_callees <目标函数>
+   codegraph_callers <目标函数>
+4. ★ 必须先读取对应的 Fortran 源码，理解原始逻辑
+5. 实现修改，连接纯计算函数到编排流程
+6. 编译验证：
+   RUSTFLAGS="-A warnings" cargo build 2>&1 | tail -5
+7. 编译失败 → 修复 → 重试
+8. 编译通过 → ★ 运行验证（见下方）→ 在 .f2r_tasks 中标记 ✅ → 取下一个任务
+```
+
+## ★ 运行验证（每项任务完成后必须执行）
+
+**编译通过 ≠ 完成。** 必须实际运行程序验证产出。
+
+```bash
+# TLUSTY 运行验证
+cd tests/tlusty/hhe_rust
+rm -f fort.7 rust.6 stderr.txt
+# 先确保有 fort.8 模型文件（如果需要）
+cp ../hhe/fort.8 . 2>/dev/null
+../../../target/debug/tlusty < hhe35lt.5 > rust.6 2>stderr.txt
+# 检查：fort.7 是否生成且非空？
+ls -la fort.7
+cat stderr.txt
+
+# SYNSPEC 运行验证
+cd tests/synspec/hhe
+cp hhe35nl.7 fort.8
+ln -sf fort.55.con fort.55 2>/dev/null
+rm -f fort.7 rust.6 stderr.txt
+../../../target/debug/synspec < hhe35nl.5 > rust.6 2>stderr.txt
+# 检查：fort.7 是否生成且非空？
+ls -la fort.7
+cat stderr.txt
+```
+
+**判定标准：**
+- ✅ `fort.7` 生成且非空 → 任务完成
+- ❌ panic / 无输出 / `fort.7` 为空 → **必须修复**，不能标记 ✅
+
+## ★ 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 ✅
+```
+
+## 已知运行问题（持续更新）
+
+| 问题 | 状态 | 详情 |
+|------|------|------|
+| TLUSTY fort.8 缺失 | 待修 | runner 在 `tests/tlusty/hhe_rust/` 中找不到 fort.8 |
+| TLUSTY 无输出 | 待修 | rust.6 为空，主循环未执行 |
+| SYNSPEC iniset panic | 待修 | `iniset.rs:161` 索引越界 `len=1, index=3` |
+| SYNSPEC nion=0 | 待修 | INITIA 原子数据未加载，nion/nlevel/natom 全为 0 |
+| SYNSPEC RDATA 空 | 待修 | 读取 0 ions, 0 levels |
+
+## ★ 核心原则
+
+```
+1. 先读 Fortran 源码：每个 TODO 都对应 Fortran 中的具体逻辑
+2. 保持调用顺序：Fortran CALL 顺序必须严格保持
+3. 正确传递参数：COMMON 块变量 → Rust struct 字段映射正确
+4. 数组下标转换：1-based → 0-based
+5. 不能用空壳：回调/closure 必须调用实际函数
+6. 每步验证编译：修改后立即 cargo build
+7. ★ 编译通过 ≠ 完成：必须实际运行程序验证产出
+```
+
+## 编译验证
+
+每次修改后：
+```bash
+RUSTFLAGS="-A warnings" cargo build 2>&1 | tail -5
+```
+
+相关模块的单元测试：
+```bash
+cargo test --lib <模块名> 2>&1 | tail -3
+```
+
+禁止全量测试，内存会被占满。
+
+## 完成标准
+
+1. `.f2r_tasks` 中所有任务标记 ✅
+2. `cargo build` 零错误
+3. 无 `TODO`/`FIXME` 遗留在生产代码中
+4. **TLUSTY 端到端运行成功**（`fort.7` 非空）
+5. **SYNSPEC 端到端运行成功**（`fort.7` 非空）
+6. 更新 `.f2r_phase` 为 `verify`
+7. 生成 Phase 3 的 `.f2r_tasks`

+[ ] I/O 语句: WRITE/READ/PRINT 对应 Rust 的文件 I/O
+[ ] 函数调用: 每个子程序调用参数正确传递
+[ ] 回调模式: 回调/closure 必须调用实际函数（不能是空壳 NoOp）
+[ ] 数学公式: 常数和计算公式与特殊函数完全一致
+[ ] 编译验证: cargo build 无错误
+[ ] DATA 语句: 已预提取到 src/data.rs
+```
+
+## 判断标准
+
+模块检查结果只有三种状态:
+```
+通过  — 逐行对比一致，调用完整，无空壳，逻辑相同。通过时立即检查下一个模块
+未通过 — 发现具体差异，修复后 cargo build 通过，但输出仍不一致
+跳过   — 不需要检查（如纯工具函数，已有充分单元测试覆盖）
+```
+
+## 修复原则
+
+```
+1. 严格对照 Fortran: 按 Fortran 代码行号逐行对比 Rust 实现
+2. 保持调用顺序: Fortran 中的 CALL 顺序必须严格保持
+3. 正确映射 COMMON: 使用 Fortran INCLUDE 文件确认变量含义
+4. 控制流程等价: IF/DO/SELECT CASE 逻辑必须一致
+5. 数组下标转换: Fortran 列主序 1-based → Rust 行主序 0-based
+6. 不能用 NoOp 回调: 如果 Fortran 有 CALL，Rust 必须调用实际函数
+7. 复杂模块分解: 分步骤修复，每步验证编译
+```
+
+## 完成标准
+
+1. TLUSTY 端到端: `fort.7` 与 Fortran 参考二进制一致
+2. SYNSPEC 端到端: `fort.7` 与 Fortran 参考二进制一致
+3. `cargo clippy` 零错误

+## 两阶段检查流程
+
+### Phase 1: Python 快速风险检测（自动）
+
+```
+步骤 1: 获取推荐模块
+$ python3 .claude/skills/f2r-check/scripts/next_module.py
+        │
+        ▼
+步骤 2: 快速检查差异
+$ python3 .claude/skills/f2r-check/scripts/f2r_check.py --diff <MODULE>
+        │
+        ├── ❌ mismatch/partial → 立即修复（现有流程）→ 步骤 4
+        │
+        └── ✅ match → 步骤 3: 风险评估
+                │
+                ▼
+步骤 3: $ python3 .claude/skills/f2r-check/scripts/f2r_check.py --risk <MODULE>
+        │
+        ├── 有 HIGH_RISK → 进入 Phase 2
+        │
+        └── 无风险 → 输出 "模块已完整，跳过" → 继续步骤 1
+```
+
+### Phase 2: Claude 深度语义对比（手动触发或自动）
+
+Phase 1 发现 HIGH_RISK 后，Claude 逐行对比 Fortran 和 Rust：
+
+```
+Phase 2 步骤:
+1. 读取 Fortran 源码
+2. 读取 Rust 源码
+3. 读取 INCLUDE 的 COMMON 定义文件
+4. 读取 use 引用的 Rust struct 文件
+5. 逐块对比（变量映射、索引转换、数组维度、赋值完整性）
+6. 发现 bug → 立即修复 → cargo build 验证
+7. 无 bug → 输出 "深度检查通过" → 继续下一个
+```
+
+### Phase 2 检查清单
+
+对每个 HIGH_RISK 模块，必须逐项检查：
+
+```
+[ ] COMMON 变量 → 正确的 Rust struct 字段
+    使用: python3 scripts/common_db.py --module <MODULE>
+
+[ ] 2D 数组下标顺序（Fortran 列主序 → Rust 行主序）
+    Fortran XDO(3,MHOD) 第一个下标变化最快
+    Rust xdo[[mhod_idx][3_idx] 需要交换下标
+
+[ ] 1-based → 0-based 索引一致性
+    IJ00=1 → ij00=0
+    DO I=1,N → for i in 0..n
+
+[ ] 循环边界转换
+    DO I=1,N → for i in 0..n (不是 0..n-1)
+    DO I=N,1,-1 → for i in (0..n).rev()
+
+[ ] IF 条件完整保留
+    <= vs <, >= vs >, .EQ. vs ==
+    .AND. vs &&, .OR. vs ||
+
+[ ] 所有赋值目标存在（无遗漏的 LINEXP 等）
+    检查每个 Fortran 赋值语句是否有对应 Rust 赋值
+
+[ ] CALL 顺序和数量一致
+    每个 CALL 都有对应 Rust 函数调用
+    调用顺序与 Fortran 一致
+
+[ ] 类型转换正确
+    INTEGER → i32, REAL*8 → f64, LOGICAL → bool
+    REAL*4 → f32, INTEGER*2 → i16
+```
+
+## 判断标准
+
+| 脚本输出 | 风险等级 | 行动 | 允许跳过？ |
+|----------|----------|------|------------|

+| `⚠️ partial` | — | 立即修复 | ❌ 否 |
+| `❌ mismatch` | — | 立即修复 | ❌ 否 |
+| `❓ missing` | — | 立即实现 | ❌ 否 |

+### 获取下一个模块
+```bash

+
+# 随机审计 5 个 match 模块
+python3 .claude/skills/f2r-check/scripts/f2r_check.py --audit
+```
+
+### Phase 2 辅助工具
+```bash
+# 查看模块使用的 COMMON 变量映射
+python3 .claude/skills/f2r-check/scripts/common_db.py --module ODFHYS
+
+# 查看 COMMON 块定义

+
+# 查看映射统计
+python3 .claude/skills/f2r-check/scripts/common_db.py --mapping
+```
+
+## 状态处理
+
+| 状态 | 行动 | 输出 | 允许跳过？ |
+|------|------|------|------------|
+| ✅ match (无风险) | 跳过 | "模块已完整，跳过" | ✅ |
+| ✅ match (有风险) | Phase 2 | "风险: 2 HIGH → 深度检查" | ❌ |

+| ❌ mismatch | 立即修复 | "修复: 修正逻辑..." | ❌ |
+| ❓ missing | 立即实现 | "修复: 实现模块..." | ❌ |
+
+## 修复原则
+
+1. **严格对照 Fortran**: 按 Fortran 代码行号，逐行对比 Rust 实现
+2. **保持调用顺序**: Fortran 中的 CALL 顺序必须严格保持
+3. **正确映射 COMMON**: Fortran COMMON 块变量 → Rust 结构体字段
+   - 使用 `common_db.py --module <NAME>` 查看映射
+4. **控制流程等价**: IF/DO/SELECT CASE 逻辑必须一致
+5. **数组下标转换**: Fortran 列主序 → Rust 行主序，1-based → 0-based
+6. **复杂模块分解**: 遇到复杂模块，分步骤修复，每步验证编译

+
+## 脚本修复规则
+
+**重要**：如果发现脚本报告有误（误报），必须修复脚本！
+
+### 脚本误报类型
+
+| 误报类型 | 原因 | 修复方法 |
+|----------|------|----------|
+| 函数别名未识别 | `COMPT0` vs `compt0_brte` | 添加到 `FUNCTION_ALIASES` |
+| 注释 I/O 被检测 | `c write(...)` 被当作必须实现 | 已修复：忽略注释行 |
+| 辅助函数调用未检测 | 主函数调用辅助函数，辅助函数包含关键调用 | 已修复：扫描整个文件 |
+
+### 如何修复脚本
+
+1. **添加函数别名**：编辑 `scripts/f2r_check.py`，在 `FUNCTION_ALIASES` 字典中添加
+2. **添加调用提取模式**：在 `call_patterns` 列表中添加新模式
+3. **修复后验证**：`python3 f2r_check.py --diff <MODULE>`
+
+## 风险检测器说明
+
+### 检测器 A: 2D 数组转置风险
+扫描 INCLUDE 文件中的 2D 数组声明（如 `XDO(3,MHOD)`），
+标记所有访问该数组的模块需要验证下标顺序。
+
+### 检测器 B: 跨 COMMON 变量混淆
+检测已知的易混淆变量对（如 JNDODF vs IJTF），
+当模块同时使用这些变量时标记。
+
+### 检测器 C: f2r_depends 诚实性检查
+对比 `// f2r_depends:` 注释中声明的函数 vs 代码中实际的调用，
+标记声明了但未实际调用的函数。
+
+### 检测器 D: 索引累加器模式
+检测 `IJ00=1`, `IJQ=IJ00+IJ` 等索引算术模式，
+标记需要验证 1-based → 0-based 转换。

+START Module Check Results
+===========================
+
+Status: FAILED
+
+Fortran Source: start.f
+Rust Implementation: /home/fmq/.zeroclaw/workspace/SpectraRust/src/tlusty/io/start.rs
+
+Issues Found:
+-------------
+1. WARNING: Rust implementation is a simplified version/placeholder
+2. ERROR: Missing call to INITIA subroutine
+3. ERROR: Missing call to PRDINI subroutine
+
+Repair Suggestions:
+-------------------
+1. Need to fully implement this module
+2. Add call: initia(&mut params)
+3. Add call: prdini(&mut params)
+
+Summary:
+--------
+The START module in Rust is incomplete. The Fortran START module is responsible
+for initializing the TLUSTY calculation, including calls to INITIA (general
+initialization) and PRDINI (PRD - Partial Redistribution initialization). The
+current Rust implementation appears to be a placeholder or simplified version
+that does not include these critical initialization steps.

+
+## Problems Identified
+

+
+| Function | Status |
+|----------|--------|
+| DWNFR0 | Missing |
+| DWNFR1 | Missing |
+| GFREE0 | Missing |
+| LINPRO | Missing |
+| OPACT1 | Missing |
+| OPADD | Missing |
+| SABOLF | Missing |

+| WNSTOR | Missing |
+
+---
+
+## Control Flow Differences
+
+| Metric | Fortran | Rust |

+| Control Statements | 43 | 75 |
+
+### Fortran INCLUDE Files
+- BASICS.FOR
+- ATOMIC.FOR
+- MODELQ.FOR
+- ODFPAR.FOR
+- ALIPAR.FOR
+
+### Fortran COMMON Block
+- `hmolab`: contains `anh2(mdepth)`, `anhm(mdepth)`
+

+
+## Fortran Code Structure
+
+```fortran
+SUBROUTINE OPACF0(ID,NFRQ)
+
+C     Absorption, emission, and scattering coefficients
+C     at depth ID
+
+C     Input:  ID   - depth point

+      DIMENSION FREDG(NLMX),S(NLMX),SUM(NLMX),PRF(MFREQL)
+```
+
+### Fortran Control Flow Sequence
+
+1. **Initialization (TDPINI-like)**
+   - Calculate temperature-related quantities
+   - `CALL GFREE0(ID)`
+   - Set `LASER = ITER.GT.ITLAS`
+
+2. **Opacity Initialization (OPAINI-like)**
+   - Set electron density scalars
+   - `if(izscal.eq.1)` branch
+   - `CALL DWNFR0(ID)`
+   - `CALL WNSTOR(ID)`
+   - `CALL SABOLF(ID)`
+
+3. **Bound-Free Opacity**
+   - `IF(IELHM.GT.0)` - H- molecule check
+   - `IF(NFRQ.GT.NFREQC)` - frequency range check
+   - `DO 10 ITR=1,NTRANS` - transition loop
+   - `IF(ISPODF.GE.1)` - ODF mode check
+   - `CALL LINPRO(ITR,ID,PRF)` - line profile
+
+4. **Laser Mode**
+   - `IF(LASER)` branch
+   - `DO 30 IBFT=1,NTRANC` - bound-free transitions
+   - `CALL SGMER1(FRINV,FR3INV,IMER,ID,SGME1)`
+   - `CALL DWNFR1(FR,FR0(ITR),ID,IZZ,DW1)`
+
+5. **Ion Loop**
+   - `DO 40 ION=1,NION`
+   - Multiple IT (ion type) branches
+
+6. **Opacity Addition**
+   - `IF(IOPADD.NE.0)` then `CALL OPADD(0,ICALL,IJ,ID)`
+   - ODF handling with `ISPODF`
+
+7. **Opacity Table**
+   - `if(ioptab.gt.0)` then `call opact1(ij)`
+
+---
+
+## Rust Code Structure
+
+The Rust implementation has similar structure but is missing the function calls:
+
+### Present in Rust:
+- Temperature initialization (lines 1-18)
+- Electron density initialization (lines 20-42)
+- Bound-free opacity preparation (lines 44+)
+- Main transition loops
+- Ion type matching
+
+### Missing in Rust:
+- All 9 function calls are commented out or not implemented
+- The code has placeholder comments like:
+  - `// CALL GFREE0(ID) - 由外部调用或在此调用`
+  - `// CALL DWNFR0(ID) - 下沉修正初始化`
+  - `// CALL WNSTOR(ID) - 氢积分存储`
+  - `// CALL SABOLF(ID) - 束缚-自由 Sa Boltzmann 因子`
+
+---
+
+## Recommendations
+
+### Priority 1: Implement Missing Functions
+
+1. **GFREE0** - Free-free Gaunt factor initialization
+2. **SABOLF** - Sa Boltzmann factor for bound-free transitions
+3. **WNSTOR** - Hydrogen integral storage
+4. **DWNFR0** - Downward correction initialization
+5. **DWNFR1** - Downward correction calculation
+6. **SGMER1** - Emergent intensity calculation
+7. **LINPRO** - Line profile calculation
+8. **OPADD** - Opacity addition
+9. **OPACT1** - Opacity table lookup
+
+### Priority 2: Add COMMON Block Data
+
+The `hmolab` COMMON block with:
+- `anh2(mdepth)` - H2 number density
+- `anhm(mdepth)` - H- number density
+
+### Priority 3: Verify Control Flow
+
+The Rust code has 75 control statements vs Fortran's 43, suggesting possible:
+- Extra conditional checks
+- More granular loop handling
+- Potential logic divergence
+
+---
+
+## Function Call Mapping
+
+| Fortran Call | Rust Equivalent | Status |
+|--------------|-----------------|--------|
+| `CALL GFREE0(ID)` | `gfree0(&mut params)` | **TODO** |
+| `CALL DWNFR0(ID)` | `dwnfr0(&mut params)` | **TODO** |
+| `CALL WNSTOR(ID)` | `wnstor(&mut params)` | **TODO** |
+| `CALL SABOLF(ID)` | `sabolf(&mut params)` | **TODO** |
+| `CALL LINPRO(ITR,ID,PRF)` | `linpro(&mut params)` | **TODO** |
+| `CALL SGMER1(...)` | `sgmer1(&mut params)` | **TODO** |
+| `CALL DWNFR1(...)` | `dwnfr1(&mut params)` | **TODO** |
+| `CALL OPADD(...)` | `opadd(&mut params)` | **TODO** |
+| `CALL OPACT1(IJ)` | `opact1(&mut params)` | **TODO** |
+
+---
+
+## Summary
+
+The Rust implementation of OPACF0 is incomplete. The core structure is present but 9 critical function calls are missing. These functions handle:
+
+1. **Free-free opacity** (GFREE0)
+2. **Bound-free opacity preparation** (SABOLF, WNSTOR)
+3. **Line profiles** (LINPRO)
+4. **Downward corrections** (DWNFR0, DWNFR1)
+5. **Emergent intensity** (SGMER1)
+6. **Opacity accumulation** (OPADD)
+7. **Opacity table lookup** (OPACT1)
+
+Without these functions, the OPACF0 module cannot correctly calculate absorption, emission, and scattering coefficients at depth.

+# OPACF0 模块 Fortran vs Rust 实现对比报告
+
+## 1. 概述
+
+**OPACF0** 是 TLUSTY 中计算单深度点吸收、发射和散射系数的核心函数。
+
+| 属性 | Fortran | Rust |
+|------|---------|------|
+| 文件路径 | `$TLUSTY/rust/tlusty/extracted/opacf0.f` | `src/tlusty/math/continuum/opacf0.rs` |
+| 代码行数 | ~363 行 | ~919 行 |
+| 函数签名 | `SUBROUTINE OPACF0(ID, NFRQ)` | `pub fn opacf0(id, nfrq, config, model, atomic, freq_params, output)` |
+
+## 2. 架构差异
+
+### 2.1 数据传递方式
+
+| 方面 | Fortran | Rust |
+|------|---------|------|
+| 数据共享 | COMMON 块全局变量 | 参数结构体传递 |

+| 原子数据 | ATOMIC.FOR COMMON | `Opacf0AtomicParams` 结构体 |
+| 输出数组 | COMMON 块中的 ABSO, EMIS, SCAT | `Opacf0Output` 结构体 |
+
+### 2.2 Rust 结构体设计
+
+Rust 实现使用了 4 个主要参数结构体：

+    iopadd: i32,    // 附加不透明度标志
+    izscal: i32,    // 密度缩放标志
+    ioptab: i32,    // 表格不透明度标志
+    iter: i32,      // 当前迭代次数
+    itlas: i32,     // 激光抑制阈值
+    qtlas: f64,     // 激光抑制参数
+}
+
+pub struct Opacf0ModelState<'a> { ... }   // 温度、密度、占据数等
+pub struct Opacf0AtomicParams<'a> { ... } // 能级、跃迁、离子数据
+pub struct Opacf0FreqParams<'a> { ... }   // 频率数组、Planck 函数
+pub struct Opacf0Output<'a> { ... }       // 输出不透明度数组
+```
+

+| SGFF0 | 3.694D8 | 3.694e8 | 匹配 |
+
+## 4. 详细差异分析
+
+### 4.1 索引转换 (正确处理)
+
+**Fortran (1-indexed):**
+```fortran
+DO IBFT=1,NTRANC
+   ITR=ITRBF(IBFT)
+   II=ILOW(ITR)
+```
+
+**Rust (0-indexed):**
+```rust
+for ibft in 0..atomic.ntranc {
+    let itr = atomic.itrbf[ibft] as usize - 1;
+    let ii = atomic.ilow[itr] as usize - 1;
+```
+
+状态: **正确转换**
+
+### 4.2 束缚-自由不透明度计算
+
+**Fortran:**
+```fortran
+ABTRA(ITR,ID)=POPUL(II,ID)
+EMTRA(ITR,ID)=POPUL(JJ,ID)*ANE*SBF(II)*WOP(II,ID)*CORR
+```
+
+**Rust:**
+```rust
+output.abtra[itr * nd + id_idx] = popul_ii;
+let emis_val = popul_jj * ane * atomic.sbf[ii] * wop_ii * corr;
+output.emtra[itr * nd + id_idx] = emis_val;
+```
+
+状态: **匹配**
+
+### 4.3 自由-自由不透明度计算
+
+**Fortran:**
+```fortran
+SFF2(ION,ID)=EXP(FF(ION)*HKT1(ID))
+SFF3(ION,ID)=POPUL(NNEXT(ION),ID)*CHARG2(ION)*SGFF
+```
+
+**Rust:**
+```rust
+output.sff2[ion_idx * nd + id_idx] = (ff_val * model.hkt1[id_idx]).exp();
+output.sff3[ion_idx * nd + id_idx] = popul_nnext * charg2 as f64 * sgff;
+```
+
+状态: **匹配**
+
+### 4.4 Mermerges 积分计算
+
+**Fortran (递归求和):**
+```fortran
+SUM(NLMX)=S(NLMX)
+DO I=NLMX-1,II0,-1
+   SUM(I)=SUM(I+1)+S(I)
+END DO
+```
+
+**Rust (简化实现):**
+```rust
+fn compute_sgmsum(...) -> f64 {
+    // 简化处理，缺少递归求和
+    s * sgm0 / gmer[id]
+}
+```
+
+状态: **不完整实现** - Rust 版本缺少完整的递归求和逻辑
+
+### 4.5 频率循环中的自由-自由计算
+
+**Fortran 氢型 Gaunt=1 (IT=1):**
+```fortran
+SF1=SFF3(ION,ID)*FR3INV
+SF2=SFF2(ION,ID)
+IF(FR.LT.FF(ION)) SF2=UN/XKF(ID)
+ABSOFF=SF1*SF2
+```
+
+**Rust:**
+```rust
+let sf1 = output.sff3[ion * nd + id_idx] * fr3inv;
+let sf2 = if fr < atomic.ff[ion] {
+    UN / output.xkf[id_idx]
+} else {
+    output.sff2[ion * nd + id_idx]
+};
+sf1 * sf2
+```
+
+状态: **匹配**
+
+### 4.6 H- 自由-自由计算
+
+**Fortran:**
+```fortran
+ABSOFF=SFFHMI(POPUL(NFIRST(IELH),ID),FR,TEMP(ID))*ELEC(ID)
+```
+
+**Rust (简化实现):**
+```rust
+fn compute_sffhmi(popul_h: f64, _fr: f64, _temp: f64) -> f64 {
+    // 简化实现，实际应调用 sffhmi 模块
+    popul_h * CFF1
+}
+```
+
+状态: **不完整实现** - Rust 使用简化公式，忽略频率和温度依赖
+
+### 4.7 最终不透明度计算
+
+**Fortran:**
+```fortran
+ABSO(IJ)=ABSO(IJ)-EMIS(IJ)*XKF(ID)
+EMIS(IJ)=EMIS(IJ)*XKFB(ID)
+```
+
+**Rust:**
+```rust
+output.abso[ij_idx] = output.abso[ij_idx] - output.emis[ij_idx] * output.xkf[id_idx];
+output.emis[ij_idx] = output.emis[ij_idx] * output.xkfb[id_idx];
+```
+
+状态: **匹配**
+
+## 5. 未实现的功能
+
+### 5.1 外部函数调用 (Rust 中标记为 TODO)
+
+| Fortran 调用 | 功能 | Rust 状态 |
+|-------------|------|----------|
+| `CALL GFREE0(ID)` | 自由-自由 Gaunt 因子初始化 | 未调用 |
+| `CALL DWNFR0(ID)` | 下沉修正初始化 | 未调用 |
+| `CALL WNSTOR(ID)` | 氢积分存储 | 未调用 |
+| `CALL SABOLF(ID)` | 束缚-自由 Sa Boltzmann 因子 | 未调用 |
+| `CALL SGMER1(...)` | Mermerges 截面计算 | 未调用 |
+| `CALL DWNFR1(...)` | 下沉修正计算 | 未调用 |
+| `CALL LINPRO(...)` | 谱线轮廓计算 | 未调用 |
+| `CALL OPADD(...)` | 附加不透明度 | 未调用 |
+| `CALL OPACT1(IJ)` | 表格不透明度 | 未调用 |
+| `SFFHMI(...)` | H- 自由-自由截面 | 简化实现 |
+| `FFCROS(...)` | 特殊自由-自由截面 | 未实现 |
+| `GFREE1(ID,X)` | 精确 Gaunt 因子 | 未实现 |
+
+### 5.2 特殊逻辑差异
+
+#### 5.2.1 izscal 标志处理
+
+**Fortran:**
+```fortran
+if(izscal.eq.1) then
+   densi(id)=un
+   densim(id)=0.
+end if
+```
+
+**Rust:**
+```rust
+if config.izscal == 1 {
+    model.densim[id_idx] = model.densi[id_idx] * model.wmm[id_idx];
+} else {
+    model.densim[id_idx] = 0.0;
+    model.densi[id_idx] = UN;
+}
+```
+
+状态: **逻辑反转** - Rust 的条件分支与 Fortran 相反
+
+#### 5.2.2 数组访问越界检查
+
+Rust 实现添加了大量边界检查：
+
+```rust
+let iatm_ii = atomic.iatm[ii] as usize - 1;
+if iatm_ii < atomic.iadop.len() && atomic.iadop[iatm_ii] > 0 && fr <= freq_params.frtabm {
+    continue;
+}
+```
+
+这是安全的做法，但 Fortran 假设数组大小足够。
+
+## 6. 测试覆盖
+
+### Rust 单元测试
+
+```rust
+#[test]
+fn test_opacf0_config_default() { ... }
+
+#[test]
+fn test_constants() { ... }
+
+#[test]
+fn test_helper_functions() { ... }
+```
+
+### 缺失的测试
+
+- 无与 Fortran 输出的数值对比测试
+- 无完整工作流集成测试
+- 无边界条件测试
+
+## 7. 总结
+
+### 完成度评估
+
+| 组件 | 完成度 | 备注 |
+|------|--------|------|
+| 主框架结构 | 100% | 所有主要循环和分支存在 |
+| 物理常数 | 100% | 完全匹配 |
+| 束缚-自由计算 | 90% | 缺少截面函数 |
+| 自由-自由计算 | 80% | 缺少精确 Gaunt 因子 |
+| Mermerges 处理 | 50% | 积分逻辑不完整 |
+| 谱线不透明度 | 70% | 缺少 LINPRO 调用 |
+| 外部模块调用 | 30% | 大多数为占位符 |
+| izscal 逻辑 | **错误** | 条件分支反转 |
+
+### 关键问题
+
+1. **izscal 逻辑错误**: Rust 中 `izscal == 1` 和 `izscal != 1` 的处理与 Fortran 相反
+2. **Mermerges 积分不完整**: 缺少递归求和逻辑
+3. **H- 自由-自由简化**: `compute_sffhmi` 使用简化公式
+4. **多个外部函数未实现**: GFREE0, DWNFR0, WNSTOR, SABOLF, SGMER1, DWNFR1, LINPRO, OPADD, OPACT1
+
+### 建议修复优先级
+
+1. **高**: 修复 izscal 逻辑错误
+2. **高**: 实现 Mermerges 递归求和
+3. **中**: 实现 SFFHMI 完整计算
+4. **中**: 添加与 Fortran 的数值对比测试
+5. **低**: 实现其他外部函数调用

+
+---
+
+## 6. 建议检查顺序
+
+1. **首先检查** `TABINT` - 不透明度表插值 (用于 `ioptab != 0` 情况)
+2. **然后检查** `INIFRT` - 从表读取频率 (用于 `ioptab > 0` 情况)
+3. **接着检查** `RTEANG` - 辐射传输角度设置
+4. **最后检查** `DMDER` 和 `GOMINI` - 工具函数
+
+---
+
+## 7. 总结
+
+INITIA 模块共有 **约 30 个直接子程序依赖**。根据现有 Rust 代码库:
+- **已完成**: 约 25 个模块
+- **需要检查**: 5 个模块 (TABINT, INIFRT, RTEANG, DMDER, GOMINI)
+- **纯函数**: 约 15 个 (易于单元测试)
+- **状态依赖**: 约 15 个 (需要传入状态结构)

+| Rust 测试 | `tests/tlusty/hhe_rust/` |
+
+## 测试方式
+
+```bash
+cargo build --bin tlusty
+cd tests/tlusty/hhe_rust
+rm -f fort.7
+../../../target/debug/tlusty < hhe35lt.5 > rust.6 2>stderr.txt
+```
+
+## 检查工作流（严格遵守）
+
+```
+每次调用本 skill 时：
+1. 读取 progress.md → 恢复检查进度
+2. 运行 Rust → 与 Fortran 对比输出
+3. 如果输出一致 → 更新 progress.md → 结束
+4. 如果输出不一致 → 从断点继续检查:
+   a. 读取 progress.md 中 "下一个待检查模块"
+   b. ★ 必须先读取对应的 Fortran 文件，逐行理解原始逻辑
+   c. 然后读取对应的 Rust 文件
+   d. 逐行对比: 调用顺序、变量映射、索引转换、逻辑分支
+   e. 发现差异 → 立即修复 → cargo build 验证
+   f. 更新 progress.md → 继续下一个模块
+5. 全部通过 → 运行测试验证 → 更新 progress.md
+```
+
+## ★ 核心原则：必须参考 Fortran 代码
+
+```
+严禁凭猜测修改代码！每次修改前必须：
+1. 先读取对应的 Fortran 源码文件
+2. 理解 Fortran 的确切逻辑流程
+3. 找到 Fortran 中的对应行
+4. 然后对照修改 Rust 代码
+
+违反此原则是产生 bug 的最主要原因。
+```
+
+## Fortran 调用链（检查顺序）
+
+从主程序开始，沿着调用链深度优先检查:
+```
+TLUSTY (tlusty.f)
+  → START (start.f)
+      → INITIA (initia.f) ★ 最大模块，927行
+      → HEDIF (hedif.f) [可选]
+      → COMSET (comset.f)
+      → PRDINI (prdini.f)
+  → RESOLV (resolv.f)
+      → INILAM, LINSEL, OPAINI ...
+      → OPACF0, OPACF1, RTEFR1 ...
+      → LUCY (lucy.f)
+      → OUTPUT
+  → ACCEL2 (accel2.f)
+  → SOLVE / SOLVES / RYBSOL
+      → MATGEN → BRTE, BHE, BRE
+      → MATINV
+```
+
+## 模块文件映射（精确路径）
+
+每个 Fortran 模块对应的 Rust 文件：
+
+| Fortran 模块 | Fortran 文件 | Rust 文件 | 子目录 |
+|-------------|-------------|-----------|--------|
+| TLUSTY | tlusty.f | `src/tlusty/main.rs` | (主程序入口) |
+| START | start.f | `src/tlusty/io/start.rs` | io/ |
+| INITIA | initia.f | `src/tlusty/io/initia.rs` | io/ |
+| HEDIF | hedif.f | `src/tlusty/math/hydrogen/hedif.rs` | math/hydrogen/ |
+| COMSET | comset.f | `src/tlusty/math/utils/comset.rs` | math/utils/ |
+| PRDINI | prdini.f | `src/tlusty/math/opacity/prdini.rs` | math/opacity/ |
+... 
+
+### 文件搜索规则
+
+查找 Fortran 模块对应的 Rust 文件时，按以下顺序搜索：
+
+1. `src/tlusty/math/{name}.rs`
+2. `src/tlusty/math/{subdir}/{name}.rs` （subdir 见下）
+3. `src/tlusty/io/{name}.rs`
+4. 特殊映射（多个 Fortran 函数合并到一个 Rust 文件）
+
+math 子目录: ali, atomic, continuum, convection, eos, hydrogen, interpolation, io, odf, opacity, partition, population, radiative, rates, solvers, special, temperature, utils
+
+特殊映射（多合一 Rust 文件）:
+- `bhe.rs` ← BHE, BHED, BHEZ
+- `gfree.rs` ← GFREE0, GFREED, GFREE1
+- `interpolate.rs` ← YINT, LAGRAN
+- `sgmer.rs` ← SGMER0, SGMER1, SGMERD
+- `ctdata.rs` ← HCTION, HCTRECOM
+- `cross.rs` ← CROSS, CROSSD
+- `expint.rs` ← EINT, EXPINX
+- `erfcx.rs` ← ERFCX, ERFCIN
+- `lineqs.rs` ← LINEQS, LINEQS_NR
+- `convec.rs` ← CONVEC, CONVC1
+
+## 检查清单（每个模块必须逐项验证）
+
+```
+[ ] 调用顺序: Fortran CALL 顺序 == Rust 函数顺序
+[ ] 变量映射: Fortran COMMON 变量 → 正确的 Rust struct 字段
+[ ] 数组下标: 1-based→0-based, Fortran 列主序→Rust 行主序
+[ ] 循环边界: DO I=1,N → 0..n, DO I=N,1,-1 → (0..n).rev()
+[ ] IF 条件: .AND.→&&, .OR.→||, .EQ.→==, .NE.→!=, 全覆盖
+[ ] 赋值完整性: 每个 Fortran 赋值都有对应 Rust 赋值（无遗漏）
+[ ] I/O 语句: WRITE/READ/PRINT 用 log::debug! 或条件打印实现
+[ ] 函数调用: 每个子程序调用参数正确传递
+[ ] 回调模式: 回调/closure 必须调用实际函数（不能是空壳 NoOp）
+[ ] 数学公式: 常数和计算公式与特殊函数完全一致
+[ ] 编译验证: cargo build 无错误
+[ ] DATA 语句（已预提取到 src/data.rs）
+```
+
+## 判断标准
+
+模块检查结果只有三种状态:
+```
+通过  — 逐行对比一致，调用完整，无空壳，逻辑相同。通过时立即检查下一个模块
+未通过 — 发现具体差异，修复后 cargo build 通过，但输出仍不一致
+跳过   — 不需要检查（如纯工具函数）
+```
+
+## 修复原则
+
+```
+1. 严格对照 Fortran: 按 Fortran 代码行号逐行对比 Rust 实现
+2. 保持调用顺序: Fortran 中的 CALL 顺序必须严格保持
+3. 正确映射 COMMON: 使用 Fortran INCLUDE 文件确认变量含义
+4. 控制流程等价: IF/DO/SELECT CASE 逻辑必须一致
+5. 数组下标转换: Fortran 列主序 1-based → Rust 行主序 0-based
+6. 不能用 NoOp 回调: 如果 Fortran 有 CALL，Rust 必须调用实际函数
+7. 复杂模块分解: 分步骤修复，每步验证编译
+```

+
+### 最新验证 (2026-06-11, session #17) — 灰大气深度网格修复
+**灰大气模型**: 不再用常数 κ=0.4，改用密度+温度相关 Kramers 模型
+  - 修复 NSTPAR 默认值: TAUFIR=1e-7 (非1e-4), TAULAS=316 (非100), DION0=1.0 (非0.5)
+  - κ = κ_es + 4.3e24 * ρ * T^(-3.5) (匹配 Fortran ROSSOP 行为)
+  - 预测-校正法积分流体静力学平衡（对应 Fortran LTEGR lines 130-182）
+**Rust NITER=30**: MD5=`4caa3baa6bf4eee367f4f32dca50acce`，31次迭代收敛
+  - 深度网格: DM 偏差 -42% ~ +29%（之前常数 κ: -99.9% ~ +45%）
+  - 温度: 偏差 -6.6% ~ +7.9%（之前: -91% ~ -41%）
+  - 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
+**Fortran 参考**: MD5=`759482772c154caef5da1c4ad5790ef6`

+**Rust NLTE (NITER=10, SOLVES=1)**: chmx ~0.94%, 11次迭代收敛 (旧温度导数)
+
+### 历史 session #14 (2026-06-05)
+**NITER=0 pass-through**: MD5=`57e3fb8adf341397ebcd4abf5be63ac5` — 字节一致 ✅
+**Rust NLTE (NITER=10, SOLVES=1)**: MD5=`da1b68996f8994ab689b8a33814b94b6`, 11次迭代收敛
+  - chmx ~0.94% (id=69 TOTN), iter=10 lfin=true
+  - SOLVES chmx: iter1=0.599 → iter2=0.011 → iter3..10≈0.009-0.018(震荡)
+  - Lambda dhhmx=0.0 (LTE 种群不参与 ALI)
+**NLTE 差异**: 已知限制 — 无 WNSTOR/SABOLF → dabt/demt 不准 → SOLVES chmx ~0.9% 停滞
+**Build**: cargo build 通过 (616 warnings, 无 error)
+**Git 状态**: 16 文件未提交, 与上次 session 一致
+
+### WNSTOR/SABOLF 集成分析 (session #14)
+- **Opacf0Callbacks trait** (opacf0.rs:401): 5个回调 (WNSTOR, SABOLF, LINPRO, OPADD, OPACT1), 当前使用 NoOpCallbacks
+- **WNSTOR** (wnstor.rs): 已实现, 计算氢占据概率 WOP/WNHINT
+- **SABOLF** (sabolf.rs): 已实现, 计算 Saha-Boltzmann 因子 + 温度导数 dSBF/dT
+- **opacf0()** (opacf0.rs:452): 完整 Fortran 等价函数, 需要 Opacf0Callbacks + 大量参数结构体
+- **resolv.rs 当前做法**: 使用简化的 Opacf0State::compute_opacity() + 有限差分 dabt/demt
+- **集成路径**: 
+  1. 创建 RealCallbacks 实现 (包装 WNSTOR+SABOLF 调用)
+  2. 填充完整参数结构体 (Opacf0AtomicParams 等, ~30个数组)
+  3. 用 opacf0() 替代 compute_opacity() 计算 dabt/demt
+  4. 估计工作量: 1-2天, 需要完整原子数据初始化
+- **之前尝试**: 人口导数有限差分(chmx→0.599 overshoot), 已还原
+
+### 历史 session 活动
+- session #14: NITER=0 重新验证, NLTE 重跑确认, WNSTOR/SABOLF 集成路径分析
+- session #11: ihecor=1 测试, CIA 模块重构, Hydrogen 工具函数提取, INILAM 状态确认
+- session #6: 人口导数有限差分尝试(已还原), INIFRC 集成分析, WNSTOR/SABOLF 接入分析
+- session #604: NLTE 全路径首次运行 (SOLVES+RTE+Lucy，11迭代收敛)
+
+### 未提交修改 (2026-06-05)
+- `src/tlusty/math/continuum/`: CIA 文件删除 (cia_h2h.rs, cia_h2h2.rs, cia_h2he.rs, cia_hhe.rs)
+- `src/tlusty/math/hydrogen/`: bhe.rs, colhe.rs, colis.rs, hedif.rs 修改, 新增 utils.rs
+- `src/tlusty/io/resolv.rs`: 修改
+- `src/tlusty/math/continuum/mod.rs`: 修改
+
+### 尝试的改进 (2026-06-05, session #6)
+1. **人口导数包含在有限差分中** (已还原): 在 T+ΔT 扰动人口但保持 ne 固定, 导致导数过大(chmx → 0.599 overshoot)。正确方法需要自洽 ne 调整, 这需要完整的 WNSTOR→SABOLF→OPACF0 管道。
+2. **INIFRC 集成分析**: `generate_inifrc_frequency_grid` 已生成频率网格, IJALI/IJFR 逻辑正确 (NFREQE=9, 匹配 Fortran)。完整 INIFRC 需要原子数据库初始化, 当前不必要。
+3. **结论**: 没有完整的 WNSTOR/SABOLF/OPACF0 管线, 不透明度温度导数无法显著改善。SOLVES chmx ~5% 平台是当前架构的固有限制。
+
+### NLTE 路径关键修复 (2026-06-05)
+1. **REINT/FCOOL**: REINT=1.0 启用积分形式辐射平衡方程，FCOOL=REINT*FCOOLI 捕获 ALI 隐式频率贡献
+2. **Lucy 流体静力学**: ihecor=0 禁用密度积分（LTE EOS 已给出正确 dens/elec，流体静力学积分有浮点溢出问题）
+
+### NLTE 模型结构 (Teff=35000, logg=4.0, HHe)
+| 深度 | dm [g/cm²] | T [K] | ELEC [cm⁻³] | DENS [g/cm³] |
+|------|-----------|-------|-------------|-------------|
+| 表面 | 2.9e-7 | 24138 | 3.8e8 | 7.3e-16 |
+| 中层 | 1.9e-2 | 26894 | 2.2e13 | 4.6e-11 |
+| 深层 | 2.98e2 | 140901 | 5.7e16 | 1.1e-7 |
+
+chmx 从 0.378 → 0.030-0.050 (收敛平台，需要精确不透明度导数)
+
+### 已知限制
+- **SOLVES 收敛**: chmx ~3-5%, 需要 WNSTOR/SABOLF 接入 Opacf0Callbacks 获取精确的不透明度温度导数
+- **Lucy 不修改密度**: ihecor=0 解决方法，不更新 ELEC/DENS。需要修复流体静力学积分中的浮点溢出
+- **START/INITIA**: 仍使用 fort.8 读入模型（简化版灰大气），需要完整实现
+- **INIFRC**: 完整实现但未在 INITIA 中调用
+
+**测试前置条件**: `fort.8` 必须存在（从 `hhe/hhe35lt.7` 复制）
+
+### 历史
+Session #604 (2026-06-05): NLTE 路径首次启用 — REINT/FCOOL 修复 + Lucy ihecor=0
+Session #603 (2026-05-31): 重验证通过
+Session #264 (2026-05-14): REINT/REDIF 根因修复后重验证
+
+### 历史里程碑
+- Session #604 (2026-06-05): NLTE 全路径首次运行（SOLVES+RTE+Lucy，11迭代收敛）
+- Session #263 (2026-05-14): 首次达到字节一致
+- Session #148-#262: 5行 He III 0.33% 差异 (浮点路径依赖)
+- Session #264: REINT/REDIF 根因修复后重验证

+
+## 已知差距(按优先级排序)
+
+1. **灰大气深度网格 (session #17 部分解决)**: Kramers κ(ρ,T) 模型给出 DM 偏差 <42%，T 偏差 <8%。进一步改善需要:
+   - 连接 ROSSOP → MEANOPT → OPCTAB 完整不透明度链
+   - 连接 ELDENS (精确 ne) → WMM (精确平均分子量)
+   - 预计需要 1-2 天完整实现
+2. **不透明度温度导数 (部分解决)**: 自洽 ne+Saha 有限差分已改善 4x (0.94%→0.23%)。进一步改善需要:
+   - WNSTOR 占据概率 (WOP < 1 修正 LTE 种群)
+   - SABOLF 解析温度导数 dsbf/dT
+   - 变量 Eddinger 因子
+3. **Lucy 流体静力学**: ihecor=1 时密度积分产生浮点溢出 → 不透明度→0 → Jν→0。需要修复 BOLK/dm 除法
+4. **INITIA 完整实现**: 当前使用简化版灰大气创建，需要完整 INITIA（含 NSTPAR namelist 解析）
+5. **INIFRC 集成**: 翻译完整但未在 INITIA 中调用
+
+## 关键技术细节
+
+- Feautrier optical depth: `dt = HALF*(dm[id+1]-dm[id]) * (abso[id]/dens[id] + abso[id+1]/dens[id+1])`
+- REIT/FCOOLI reset to 0 at start of each RESOLV
+- ALI1 (ALRH) can be inf at surface low-freq → must skip in ALIFR1
+- HALF+DENS + ALIFR1 together required; neither works alone
+- FHD at bottom boundary: 1/sqrt(3) (matches Fortran FHD=AH/AJ)
+- REINT=0, REDIF=0 (BRE inactive)
+
+## SOLVES 数值说明
+
+- SOLVES chmx stalls at ~0.009 (doesn't converge to <1e-3)
+- NITER>20 causes oscillation and drift (NITER=10 is optimal)
+- Variable Eddington factor (NMU=4) destabilizes SOLVES without analytic derivatives
+- 第1次 SOLVES 迭代出现 NaN (bet/alf/dpsi), 但 chmx=0 所以无影响

+### Summary
+f2r-check 模块检查策略：优先修复依赖链短的模块
+
+### Details
+在 TLUSTY/SYNSPEC Fortran 到 Rust 迁移中，使用 f2r-check 检查模块一致性时：
+
+1. **OPACF0** 是核心不透明度模块，被调用 7 次，有 9 个子程序调用缺失
+   - 其中 6 个已实现（GFREE0, DWNFR0, DWNFR1, WNSTOR, SGMER1, OPACT1），只需取消注释
+   - 3 个需要先修复依赖（SABOLF→PARTF, LINPRO→5个调用, OPADD→5个CIA调用）
+
+2. **推荐优先级**：先修复依赖链短的模块
+   - IJALI2：只需添加 QUIT 调用
+   - LEVCD：只需添加 INDEXX 和 QUIT 调用
+
+3. **依赖链分析**：
+   - ✅ = 完全匹配，可直接使用
+   - ❌ = 有缺失调用，需修复
+   - ⚠️ = 部分实现
+
+### Suggested Action
+使用 `python3 .claude/skills/f2r-check/scripts/next_module.py` 获取下一个待检查模块，
+然后使用 `python3 .claude/skills/f2r-check/scripts/f2r_check.py --diff <MODULE>` 查看详细差异。

+//! Each function reads a CIA table on first call, then performs 2D bilinear

+//!
+//! # Usage
+//! 1. Call the `*_init` function once to load the CIA data file.
