v4.3 gives students two clear routes. Lightweight on-demand starts teaching immediately and processes only the pages currently being studied. Full knowledge-base mode is an explicit choice that organizes the complete course, builds the standard question bank, and can produce a printable, verifiable Study Guide.
Highlights:
- Lightweight on-demand is the recommended default: no whole-course preprocessing and no automatic PDF generation, while figures and detailed explanations stay intact.
- Full mode supports a recoverable one-question-per-turn teaching cadence.
- Study Guides use item-specific crops, readable formulas, beginner-first answer explanations, strict source/version checks, and page-by-page visual review.
- When the host can prove a fresh, single-item, tool-restricted child context, the Study Guide uses a native isolated child agent by default. No separate API key is required. A separately billed external Provider remains an explicit-request fallback with exact-plan pricing, privacy, scope, and upload consent.
- MinerU, Docling, and LangGraph remain named-request-only remote integrations; the skill never silently installs their heavy local dependencies.
- Both READMEs now provide plain-language feature scores, copyable enable/install prompts for Codex, Claude Code, Cursor, Windsurf, Antigravity, and Gemini CLI, plus a desktop/IDE recommendation for image-heavy studying.
- The detailed benchmark charts, costs, and Star History display are restored.
- The release incorporates and hardens the step-by-step teaching workflow from PR #41.
Install: copy the platform-specific instruction from the English README, or download universal-exam-cram-coach.zip when your agent cannot install it directly. See CHANGELOG.md for the complete history.

v4.3 把使用方式分成两条清楚的路线：推荐的轻量按需会马上开始复习，只处理当前学到的页面；明确选择完整建库后，才会整理全课程知识库、标准题库，并制作可打印、可核验的复习讲义。
主要变化：
- 默认轻量按需，不预处理整门课，不自动生成 PDF；题面图和详细讲解仍完整保留。
- 完整模式支持每轮一道例题的可恢复教学节奏。
- 复习讲义按题裁掉无关内容，直接显示公式，为答案提供零基础详解，并加强来源、材料版本和逐页视觉核验。
- 平台能够证明“每题全新上下文、只传当前题、限制无关工具”时，讲义默认使用内部独立子智能体逐题解释，不需要另一把接口密钥。另行计费的外部模型只作为用户明确要求后的备用方案，仍需对准确价格、隐私、范围和上传作单独同意。
- MinerU、Docling 和 LangGraph 只允许用户点名后的远程集成，不会静默安装重型本地依赖。
- 中英文 README 都加入了说人话的功能评分、可直接复制的启用与安装口令，覆盖 Codex、Claude Code、Cursor、Windsurf、Antigravity 和 Gemini CLI；有图教材建议优先使用桌面软件或编辑器界面。
- 完整实测图表、费用表和 Star History 已恢复展示。
- 吸收并加固了 PR #41 的逐题教学流程。
安装：复制中文 README里对应平台的口令；只有智能体无法自行联网安装时，才需要手动下载 universal-exam-cram-coach.zip。完整历史见 CHANGELOG.md。
