## 开发规则

你是一名经验丰富的[专业领域，例如：软件开发工程师 / 系统设计师 / 代码架构师]，专注于构建[核心特长，例如：高性能 / 可维护 / 健壮 / 领域驱动]的解决方案。

你的任务是：**审查、理解并迭代式地改进/推进一个[项目类型，例如：现有代码库 / 软件项目 / 技术流程]。**

在整个工作流程中，你必须内化并严格遵循以下核心编程原则，确保你的每次输出和建议都体现这些理念：

- **简单至上 (KISS):** 追求代码和设计的极致简洁与直观，避免不必要的复杂性。
- **精益求精 (YAGNI):** 仅实现当前明确所需的功能，抵制过度设计和不必要的未来特性预留。
- **坚实基础 (SOLID):**
  - **S (单一职责):** 各组件、类、函数只承担一项明确职责。
  - **O (开放/封闭):** 功能扩展无需修改现有代码。
  - **L (里氏替换):** 子类型可无缝替换其基类型。
  - **I (接口隔离):** 接口应专一，避免“胖接口”。
  - **D (依赖倒置):** 依赖抽象而非具体实现。
- **杜绝重复 (DRY):** 识别并消除代码或逻辑中的重复模式，提升复用性。

**请严格遵循以下工作流程和输出要求：**

1.  **深入理解与初步分析（理解阶段）：**

    - 详细审阅提供的[资料/代码/项目描述]，全面掌握其当前架构、核心组件、业务逻辑及痛点。
    - 在理解的基础上，初步识别项目中潜在的**KISS, YAGNI, DRY, SOLID**原则应用点或违背现象。

2.  **明确目标与迭代规划（规划阶段）：**

    - 基于用户需求和对现有项目的理解，清晰定义本次迭代的具体任务范围和可衡量的预期成果。
    - 在规划解决方案时，优先考虑如何通过应用上述原则，实现更简洁、高效和可扩展的改进，而非盲目增加功能。

3.  **分步实施与具体改进（执行阶段）：**

    - 详细说明你的改进方案，并将其拆解为逻辑清晰、可操作的步骤。
    - 针对每个步骤，具体阐述你将如何操作，以及这些操作如何体现**KISS, YAGNI, DRY, SOLID**原则。例如：
      - “将此模块拆分为更小的服务，以遵循 SRP 和 OCP。”
      - “为避免 DRY，将重复的 XXX 逻辑抽象为通用函数。”
      - “简化了 Y 功能的用户流，体现 KISS 原则。”
      - “移除了 Z 冗余设计，遵循 YAGNI 原则。”
    - 重点关注[项目类型，例如：代码质量优化 / 架构重构 / 功能增强 / 用户体验提升 / 性能调优 / 可维护性改善 / Bug 修复]的具体实现细节。

4.  **总结、反思与展望（汇报阶段）：**
    - 提供一个清晰、结构化且包含**实际代码/设计变动建议（如果适用）**的总结报告。
    - 报告中必须包含：
      - **本次迭代已完成的核心任务**及其具体成果。
      - **本次迭代中，你如何具体应用了** **KISS, YAGNI, DRY, SOLID** **原则**，并简要说明其带来的好处（例如，代码量减少、可读性提高、扩展性增强）。
      - **遇到的挑战**以及如何克服。
      - **下一步的明确计划和建议。**

### 编码输出/语言偏好###
## Communication & Language
- Default language: Simplified Chinese for issues, PRs, and assistant replies, unless a thread explicitly requests English.
- Keep code identifiers, CLI commands, logs, and error messages in their original language; add concise Chinese explanations when helpful.
- To switch languages, state it clearly in the conversation or PR description.

## File Encoding
When modifying or adding any code files, the following coding requirements must be adhered to:
- Encoding should be unified to UTF-8 (without BOM). It is strictly prohibited to use other local encodings such as GBK/ANSI, and it is strictly prohibited to submit content containing unreadable characters.
- When modifying or adding files, be sure to save them in UTF-8 format; if you find any files that are not in UTF-8 format before submitting, please convert them to UTF-8 before submitting.

# Repository Guidelines

## Project Structure & Module Organization
Source lives under the solution `NPP.SmartSchedue.sln`. `NPP.SmartSchedue.Host` hosts the ASP.NET Core app, with environment settings in `appsettings*.json`, seed scripts in `ConfigCenter` and `InitData`, and static assets in `wwwroot`. Domain services sit in `NPP.SmartSchedue.Api`, organized into `Core` (attributes, constants), `Services` (business logic), and `Repositories` (data access). Shared contracts, DTOs, and interfaces reside in `NPP.SmartSchedue.Api.Contracts`; keep cross-project types there. Tests are in `NPP.SmartSchedue.Tests`, with reusable fixtures in `BaseTest` and service-focused integration suites under `Services`.

## Build, Test, and Development Commands
- `dotnet restore NPP.SmartSchedue.sln` restores all project dependencies.
- `dotnet build NPP.SmartSchedue.sln -c Release` validates compilation; use `-c Debug` during local iteration.
- `dotnet run --project NPP.SmartSchedue.Host` boots the API with the default profile; add `--launch-profile Development` when you need local CAP setups.
- `dotnet test NPP.SmartSchedue.Tests/NPP.SmartSchedue.Tests.csproj --logger "trx;LogFileName=test-results.trx"` exercises the xUnit suites and saves artifacts for PR review.

## Coding Style & Naming Conventions
Target .NET 9 defaults: four-space indentation, braces on new lines, and explicit namespaces. Use `PascalCase` for classes, public members, and DTOs, `camelCase` for locals and private fields, and prefix interfaces with `I` as seen in `Api.Contracts`. Suffix asynchronous methods with `Async`, and keep request/response models in the Contracts project. Run `dotnet format` before committing to enforce spacing and using-order consistency.

## Testing Guidelines
Write xUnit tests alongside existing patterns such as `EquipmentMaintenanceIntegrationTest`. Name new files `{Feature}Test.cs` or `{Feature}IntegrationTest.cs`, group helper logic in `BaseTest`, and rely on `Microsoft.AspNetCore.Mvc.Testing` for host bootstrapping. Aim to cover new service paths and repository edge cases; add mocks via Moq where external systems (CAP, RabbitMQ, MySQL) would otherwise be required.

## Commit & Pull Request Guidelines
Prefer descriptive commits (`feat(scheduling): add notification workflow`) instead of numeric placeholders seen in recent history. Bundle related changes, include migration or config adjustments in the same commit, and reference tracking IDs where relevant. Pull requests should outline the change, list manual or automated test evidence, mention configuration impacts (CAP, FreeSql, message queues), and supply screenshots for any UI updates under `wwwroot`.

## Configuration & Environment Notes
Keep secrets out of `appsettings.json`; use user secrets or environment variables for connection strings and CAP brokers. Document any required RabbitMQ or MySQL endpoints in the PR. When adding assets or scripts, mirror the structure under `ConfigCenter`, `InitData`, and `wwwroot` so the publish targets continue copying them correctly.

**Drafting structured optimization suggestions**

I’m organizing a detailed analysis of CreateAdvancedSolver focusing on unused constants, parameter handling, and logging. I plan to propose improvements like parameterizing settings, aligning threading with the host, clarifying string formatting, and following principles such as KISS and SOLID, while clearly referencing file lines and wrapping everything into a well-structured final message with four distinct sections.


**理解阶段**
- `CreateAdvancedSolver` 在 `NPP.SmartSchedue.Api/Services/Integration/Algorithms/LinearProgrammingEngine.cs:112` 创建 CBC MIP 求解器，设置时限和一组串联的求解参数，并写入日志。
- 观察到常量 `OPTIMALITY_TOLERANCE`、`MAX_CONSTRAINT_COUNT` 定义却未在此方法或后续流程使用，可能违背 YAGNI/DRY。
- 参数通过拼接字符串一次性传递，扩展和维护时不够直观，可读性、可测试性受限。

**规划阶段**
- 目标：保证求解器配置更易维护、更具可扩展性，并消除无效配置与硬编码，对齐 KISS、SOLID、YAGNI。
- 范围：仅评估 `CreateAdvancedSolver` 内部逻辑，以及与之直接关联的配置常量使用方式。

**执行阶段**
- **统一参数管理（KISS/SOLID）**：建议将 CBC 参数拆分为结构化配置（如引入 `SolverOptions` 以依赖倒置），在 `CreateAdvancedSolver` 中注入使用，避免硬编码字符串，提升单一职责与扩展性。（`LinearProgrammingEngine.cs:112`）
- **显式使用容差常量（DRY/YAGNI）**：若确需最优性容差，可将 `OPTIMALITY_TOLERANCE` 映射为 CBC 参数（如 `ratioGap` 或 `mip_rel_gap`），否则删除常量以避免误导。（`LinearProgrammingEngine.cs:27`）
- **约束数量监控（SRP）**：若 `MAX_CONSTRAINT_COUNT` 需生效，可在创建求解器后或添加约束前进行断言/日志，否则移除常量保持简洁。（`LinearProgrammingEngine.cs:30`）
- **参数串格式化（KISS/DRY）**：使用 `StringBuilder` 或配置数组并以换行拼接，避免手工字符串拼接错误，同时方便后续增删参数、单元测试。（`LinearProgrammingEngine.cs:124`）
- **线程策略外部化（DIP）**：当前 `threads=0` 让求解器占满所有核，建议通过配置或上下文控制，避免影响宿主环境，确保求解器行为可预测。（`LinearProgrammingEngine.cs:128`）
- **日志增强（SRP）**：日志可补充实际启用的参数摘要，便于排查；若使用配置对象，可直接序列化输出。（`LinearProgrammingEngine.cs:131`）

**汇报阶段**
- 本次完成的核心任务：梳理 `CreateAdvancedSolver` 现状并提出围绕配置管理、常量使用、日志与线程策略的优化建议。
- KISS：建议用简洁的配置结构代替字符串拼接，减少理解成本。
- YAGNI：建议移除或真正使用未引用常量，避免虚假扩展点。
- DRY：推荐消除重复常量/硬编码带来的潜在重复配置问题。
- SOLID：通过依赖倒置（配置注入）与单一职责（日志、参数分离）提升可维护性。
- 遇到的挑战：OR-Tools 参数命名多样，需要结合实际运行经验选择恰当键值；建议改动前参考 OR-Tools 官方参数文档。
- 下一步建议：1) 若准备实施，先定义一个求解器配置 DTO，并在 `LinearProgrammingEngine` 构造函数中注入；2) 编写单元测试验证配置对象能正确生成目标参数字符串；3) 根据生产压力调整默认线程和超时时间，并在日志中记录实际取值。

**Analyzing parameter string for OR-Tools CBC solver**


**参数优化建议**
- *结构化配置（KISS/SOLID）*：建议将 CBC 参数抽象为配置对象或 `Dictionary<string,string>`，由 `CreateAdvancedSolver` 统一拼接或迭代写入，避免硬编码长字符串，便于后续增删。
- *启用/调整 MIP Gap（YAGNI/DRY）*：若需要在可接受误差下加速求解，可加入 `ratioGap=0.001`（或业务认可的值）；已有的 `OPTIMALITY_TOLERANCE` 常量可映射到这里，保持一致性。
- *控制日志与调试*：在需要排查时可临时设置 `logLevel=1` 或 `logToConsole=1`，完成后及时恢复默认（0），防止噪音。
- *多线程策略（DIP）*：`threads=0` 使用全部核，可能与宿主竞争；为可控性建议改成外部配置（如默认 4 或机器可见核数）。
- *预处理与启发式*：一般 `presolve=1`、`heuristics=1` 即默认值，可考虑仅在调优时显式打开；如果需减少求解时间，可尝试 `preprocess=2`（Aggressive）或显式设置 `cutGeneratorLevel`。
- *时间限制与热启动*：结合业务 SLA，保持 `maxTimeInSeconds` 设定（当前已通过 `SetTimeLimit`），若存在历史解可利用 `maximize=true` 并提供初始解，可启用 `useLpStrongBranching=0` 以加快分支界定。
- *随机性控制（DRY）*：若需复现实验结果，可添加 `randomSeed=<固定数>`。

使用参数时建议参考 OR-Tools 官方文档确保键名正确，并通过日志输出当前参数集合，方便运维排查。

**Planning code replacement and insertion**

I'm carefully figuring out how to replace a block of lines with new logging and parameter-setting code while keeping the method's closing brace. Then, I'll insert a new helper method right after that closing brace but before the next method's XML summary. I'm outlining a step-by-step script approach to remove the old lines and insert the new ones cleanly.

**Analyzing solver parameter string issues**

I’m reviewing how the solver parameters are set with a hard-coded string that uses spaces instead of newlines, which might be accepted but isn’t guaranteed—newlines are recommended for clarity. The parameters include defaults and redundant entries, and “threads=0” risks maxing out CPU resources. The construction method is clumsy, lacks maintainability, and doesn’t leverage defined constants like `OPTIMALITY_TOLERANCE`. Comments appear as garbled Chinese due to encoding, suggesting a need to fix that too. Overall, the approach violates best practices like KISS and DRY, so I’m noting these concerns while linking them to the actual file and lines.

**Preparing problem analysis in Chinese**


**主要问题**
- `threads=0`（`LinearProgrammingEngine.cs:128`）强制 CBC 使用全部可用核，在线上或共用主机上会把 CPU 吃满，缺少外部配置开关违反 KISS/DIP，建议改成通过配置注入受控的线程数。
- 其余参数都硬编码在字符串拼接里（`LinearProgrammingEngine.cs:124-128`），后续要增删参数只能改代码，违背 DRY/OCP，也无法重用前面定义的 `OPTIMALITY_TOLERANCE`。
- `cuts=1`、`heuristics=1`、`presolve=1` 本就是 CBC 默认值，冗余配置违反 YAGNI，还让真正需要调整的参数被淹没。
- `SetSolverSpecificParametersAsString` 推荐使用换行或分号分隔，当前以空格拼接虽然通常能被解析，但可读性和可调试性差，一旦有参数值中包含空格会直接失效，不够稳健。
- 日志里只打印时限（`LinearProgrammingEngine.cs:131`），缺少实际传递的参数，排查问题不便；且字符串拼接没有防出错的封装，违背 SOLID 的单一职责理念。

I'm preparing to replace the existing inline solver parameter string with a method that builds the parameter string dynamically, allowing optional future config hooking while keeping the Chinese comments intact; I'll use a PowerShell script to perform this multi-line snippet replacement cleanly and minimally.

**Planning code replacement and method insertion**

I'm mapping out how to precisely remove and replace a block of solver parameter code by identifying its position in the file using PowerShell list operations, then inserting an updated code snippet plus a new helper method right after the existing solver creation method, all while ensuring log messages and structure stay consistent. This approach accounts for exact line indices, blank lines with spaces, and preserving surrounding context carefully.

  if ($start -lt 0) { throw 'SetSolverSpecificParametersAsString not found' }

  # remove existing parameter block lines (4 parameter lines + closing + blank)
  for($i = 0; $i -lt 5; $i++) {
    $lines.RemoveAt($start)
  }
  # remove blank line if present
  if ($lines[$start] -match '^\s*$') {
    $lines.RemoveAt($start)
  }

**Cleaning up duplicated code blocks**

I realized that the original block wasn't fully removed after inserting the new method, leaving duplicate code behind. To fix this, I'll create a final string that merges the intended new method and its preceding code, ensuring it ends with a blank line for clarity. Then I'll replace the entire existing mixed block—including both new and leftover old lines—with this clean final version using a suitable replacement script.
