# Task: Restore teacher conversation context and project file reading
|
||||
|
||||
## Identity
|
||||
|
||||
- Task ID: 20260922-teacher-context-c40f7b51
|
||||
- Mode: Feature
|
||||
- Branch: codex/20260922-teacher-context-c40f7b51-teacher-context
|
||||
- Worktree: D:\Datas\OthersProjects\.codex-worktrees\makelore\20260922-teacher-context-c40f7b51
|
||||
- Base commit: 7f5131e92fb06f3357ca45f18aaead0e2eaa87e0
|
||||
- Owner: codex
|
||||
- Status: Ready for Integration
|
||||
|
||||
## Scope
|
||||
|
||||
- 复现并修复云端老师无法获得当前来源会话上下文的问题，并支持按需只读当前项目文件。
|
||||
- 以实际 Main service/model 路径建立失败测试；根据证据修复上下文准备、文件读取及必要 UI 提示，完成相关测试、类型检查和构建。
|
||||
|
||||
## Intent And Constraints
|
||||
|
||||
- 使用 maintain-project-docs 与 diagnosing-bugs；Concurrent Task Gate / Planning Gate Passed，官方 start/status 已确认本任务独占 feature worktree。106 个 owner 任务记录已读取；既有未知范围保持只读，无已确认阻塞冲突。
|
||||
- 用户明确批准官方 release-missing 清除 17 条工作目录缺失的已完成任务登记；均已完成，只删除登记，保留分支和提交。此前 start 因此被阻断，未绕过门禁写代码。
|
||||
- 用户本次要求老师读取会话和项目文件，授权修正旧“无文件访问”边界；只读当前项目，不增加文件修改、命令执行、跨项目/账号读取或 Pi 编程执行能力。不创建子智能体。
|
||||
- 先通过真实路径的确定性测试捕获缺失上下文，再定位和修复。已复现长来源消息导致上下文全部被删除、无文件工具导致原生工具请求失败；冷会话历史恢复测试通过。未读取用户真实会话或调用真实付费模型，不将测试复现等同于用户当时运行日志。
|
||||
- 定位文档中模板空白以 README、AGENTS 与可执行代码补充；canonical 项目记忆仅提出 promotion，不在 feature 中修改。
|
||||
|
||||
## Outcome
|
||||
|
||||
- Main 老师服务现将当前项目路径、当前 active-branch 完整文本和当前老师话题的已完成历史交给本地只读工具。支持浏览目录、按行读取 UTF-8 文件和按消息 ID 读取本轮会话原文；允许 `.makelore/project.json` 配置，拒绝其他 `.makelore` 会话数据、Git 内部数据和越界路径。复用已有文件读取服务的项目边界、文本校验和 256 KiB 预览限制。
|
||||
- 原预算算法会逐条移除全部来源消息，长中文项目分析可只留下当前含糊追问。现在保留最近问题/回答的首尾节选；同时节选过长的上一轮老师回复，避免预留读取预算后连续追问失败。节选包含消息 ID，并可通过工具恢复中间原文；当前问题、明确引用和系统指令仍保留，超预算明确报错。
|
||||
- 原生 SSE 支持分片工具调用参数、只读结果回传和继续生成；每轮最多六批读取后要求最终文本，计算工具定义/结果/原生思考的输入预算，成组省略较早工具轮次并累计模型用量。思考内容仅用于 Main 内原生后续请求，不发给 Renderer、不持久化。每次读取和后续模型调用检查账号与取消状态。
|
||||
- UI 标明结合当前会话和项目文件答疑，显示上下文节选提示；既有话题无需迁移或重新创建，运营试聊仍不获得真实项目工具。README 已同步当前行为。
|
||||
- 本次只修改客户端，未修改云端协议、运营配置或数据库；不合并、不推送、不部署，不清理任务工作目录。
|
||||
|
||||
## Verification
|
||||
|
||||
- Red-capable loop：实际 CodingTeacherService 长来源测试首先失败，模型请求只含系统指令与当前追问；prepareTeacherModel 原生读取测试首先失败 `teacher_tools_unavailable`；长老师历史追问测试首先失败 `teacher_context_too_long`。修复后均通过。
|
||||
- `pnpm exec vitest run tests/unit/coding-teacher.test.ts tests/unit/coding-teacher-model.test.ts tests/unit/coding-teacher-read-tools.test.ts tests/unit/coding-teacher-ui.test.tsx`：44 passed。覆盖真实 service → source → model → 本地文件 → model continuation，冷历史 active branch、节选、老师原文恢复、路径边界、取消/账号变化、分片参数、原生思考、累计用量、读取轮数和输入预算、旧 UI 行为。
|
||||
- `pnpm exec vitest run tests/unit/coding-project-files.test.ts tests/unit/pi-session-projector.test.ts`：12 passed。
|
||||
- `pnpm exec playwright test tests/e2e/pi-coding-first-chat.spec.ts --grep 'project teacher side chat'`：1 passed；使用现有隔离 Electron fixture 验证新提示及带回主会话草稿，云端/模型边界为测试替身。
|
||||
- `pnpm run typecheck`、修改生产文件的定向 ESLint、`pnpm run build:vite`、`git diff --check`：通过。依赖使用仓库锁定的 pnpm 10.33.4 / frozen lockfile，锁文件未变化。
|
||||
- `pnpm exec tsc --project tsconfig.node.json --noEmit --composite false`：报告 66 条错误，与已记录 Main 基线数量一致；老师模块和 project-files 无诊断。未宣称全量 Main 类型检查通过，未扩大修复其他模块。
|
||||
|
||||
## Follow-ups
|
||||
|
||||
- 集成时将本任务提交合入客户端 main，并按发布流程更新客户端后进行真实老师模型验收；本地测试未消费真实模型点数。
|
||||
- Main 全量类型检查的既有 66 条错误不在本次范围。
|
||||
|
||||
## Promotion Candidates
|
||||
|
||||
- Target：`.project-docs/10-decisions/ADR-2026-09-22-coding-teacher.md`、对应 decision index、`20-architecture/` 老师数据流与 current-state。Proposal：将原“纯文字、无工具、无项目文件”边界更新为“Main 直接请求计费网关，有限的当前项目/当前会话只读工具，仍无 Pi 执行、写文件或命令”。Evidence：用户本次明确要求恢复会话和文件读取，新增 service/model/读取回归与 Electron UI 测试通过。Future impact：后续老师配置、客户端与联调应依此能力边界；云端发布载荷不变。Semantic conflict：旧 ADR 的 no-tools/no-files 明确冲突，不能把旧约束当成当前需求。Human confirmation：用户本次问题已授权该只读边界修正，集成时无需再次询问同一项授权。
|
||||
- Target：current-state / evidence index。Proposal：记录 UTF-8 字节预算逐条删消息可丢光长主会话；应保留最近问答节选，并提供本轮只读原文恢复。Evidence：原实现确定性失败测试与修复后通过的长来源、长老师回复和读取原文测试。Future impact：后续预算调整必须覆盖连续追问和工具结果开销。Semantic conflict：无；无需额外人类确认。

### 云端编程老师

- 主会话标题栏的“问老师”打开右侧独立聊天。老师按运营发布的提示词、文本教学 Skills、模型和原生思考选项回答，并按预算读取当前主会话已完成分支的文本与用户明确引用。Main 直接调用既有计费网关，不创建 Pi worker，不携带工具。

|
||||
- 老师可按需只读当前项目的目录与 UTF-8 代码文件（包括 `.makelore/project.json` 项目配置），复用 Main 的项目路径边界和 256 KiB 文件预览上限，按行读取并标明截断。读取结果经同一计费网关送给老师，单轮最多六批读取后生成回答；累计用量涵盖所有模型请求。不能修改文件或执行命令，也不能读取 `.makelore` 内其他账号/会话记录或 `.git` 内部数据。每次读取与后续模型请求都检查账号和取消状态；运营试聊不提供项目读取工具。
|
||||
- 老师话题按当前云端账号、项目和来源会话保存，创建时固定发布版本；每轮发送重新检查启停。关闭面板或切换会话不取消已接受的问题，退出账号会中止。请求先落盘再调用模型，同一请求标识不重复发送，重启后未完成请求标记中断。
|
||||
- 回答可复制或追加到主输入框草稿，由用户决定发送；归档来源需先恢复。删除来源会话会停止并删除关联老师记录。运营草稿试聊使用 `niancode://coding-teacher/preview?draft_revision=N` 打开独立示例上下文，不读取学生项目，要求桌面当前账号具有运营权限。
