+
+## [0.2.1] - 2026-04-26
+
+### Features
+
+- **[VoxCPM2](https://github.com/OpenBMB/VoxCPM) TTS provider with voice cloning** — OpenMAIC adapts to user-managed VoxCPM backends (vLLM-Omni, Nano-VLLM, official Python API). Clone any voice from a reference audio clip you upload or record in the browser, or let Auto Voice generate a fitting voice from each agent's persona at synthesis time. Voice profiles are stored locally to keep the serverless setup model. The Agent Bar exposes a searchable, previewable voice picker that draws from the global VoxCPM voice pool [#496](https://github.com/THU-MAIC/OpenMAIC/pull/496)
+- **Per-model thinking configuration** — First-class metadata for each model's reasoning capability (effort levels, on/off toggle, adjustable budget, or fixed thinking) flows through chat and all generation paths and is mapped to the right provider-specific request fields (Anthropic `thinking`, OpenAI `reasoning`, etc.). The model selector becomes a unified provider/model/thinking popover with compact search and a much smaller toolbar footprint [#494](https://github.com/THU-MAIC/OpenMAIC/pull/494)
+- **End-of-course completion page with persistent quiz state** — When the outline is fully materialized, students see a course-complete view with quiz score card, scene-type stat cards, and a (motion-respecting) confetti celebration. Quiz answers persist on submit and grading results persist on completion, so navigating away and back restores the reviewing state with AI feedback intact instead of resetting [#484](https://github.com/THU-MAIC/OpenMAIC/pull/484)
+- Add latest released models including [GPT-5.5](https://github.com/THU-MAIC/OpenMAIC/pull/487), DeepSeek-V4 (`-pro`, `-flash`), Xiaomi [MiMo](https://github.com/XiaomiMiMo) (`mimo-v2.5-pro`, `mimo-v2.5`), Tencent [Hy3](https://github.com/Tencent-Hunyuan), and [OpenRouter](https://openrouter.ai/) as a multi-provider gateway [#481](https://github.com/THU-MAIC/OpenMAIC/pull/481) [#487](https://github.com/THU-MAIC/OpenMAIC/pull/487)
+- Add OpenAI image generation (GPT-Image-2) as a media provider [#481](https://github.com/THU-MAIC/OpenMAIC/pull/481)
+- Refresh built-in model registries across Anthropic, DeepSeek, Kimi, Qwen, MiniMax, Grok, OpenAI, GLM, SiliconFlow, and Ollama; persisted local settings now rehydrate in registry order so newly curated lists appear consistent without clearing state [#481](https://github.com/THU-MAIC/OpenMAIC/pull/481)
+- Add inline search for recent classrooms on the home page with deferred filtering by name and description, keyboard-driven open/clear/collapse [#476](https://github.com/THU-MAIC/OpenMAIC/pull/476)
+- Add Deep-Interactive badge on classroom thumbnails for sessions generated with Interactive Mode [#478](https://github.com/THU-MAIC/OpenMAIC/pull/478)
+- Replace always-included media instruction blocks in generation prompts with conditional snippet includes gated on `imageEnabled` / `videoEnabled` — disabled capabilities are removed from the prompt entirely instead of relying on negative-override directives the model often ignored [#490](https://github.com/THU-MAIC/OpenMAIC/pull/490) (by @YizukiAme)
+
+### Bug Fixes
+
+- Fix language drift between outline and scene generation by unifying the languageDirective across the pipeline so the same target language flows from outline planning through every per-scene call [#474](https://github.com/THU-MAIC/OpenMAIC/pull/474)
+
+### Other Changes
+
+- Refactor whiteboard role prompts to file-based markdown templates and add a geometry-conflict detector (overlap, line-through-bbox, canvas clipping) that surfaces problems back to the model. Eval (flash, repeat 3, gemini-3.1-pro scorer) shows overall quality 5.4 → 6.1 and overlap 6.3 → 8.1 from prompt + detector alone [#485](https://github.com/THU-MAIC/OpenMAIC/pull/485)
+- Migrate orchestration prompt builders (`buildStructuredPrompt`, `buildDirectorPrompt`, `buildPBLSystemPrompt`) from inline TS template literals to file-based markdown templates under `lib/prompts/`, sharing the loader infrastructure with the generation pipeline. `prompt-builder.ts` 890 → 314 lines; future content tweaks land as markdown edits [#459](https://github.com/THU-MAIC/OpenMAIC/pull/459)
+
+## [0.2.0] - 2026-04-20
+
+### Features
+
+- **Deep Interactive Mode** — Generate hands-on interactive scenes (3D visualization, simulation, game, mind map/diagram, online programming) with an AI teacher who operates the UI to guide students. Fully responsive across desktop, tablet, and mobile [#461](https://github.com/THU-MAIC/OpenMAIC/pull/461)
+- Add code element support on the whiteboard — AI agents can write, display, and reference runnable code during lessons [#385](https://github.com/THU-MAIC/OpenMAIC/pull/385) (by @cosarah)
+- Add Arabic (ar-SA) interface language [#431](https://github.com/THU-MAIC/OpenMAIC/pull/431) (by @YizukiAme)
+- Add MinerU Cloud API as a PDF parsing provider, with a dedicated settings UI [#438](https://github.com/THU-MAIC/OpenMAIC/pull/438)

+- Add international base URL shortcuts for GLM, Kimi, and MiniMax in provider settings [#449](https://github.com/THU-MAIC/OpenMAIC/pull/449)
+- Add anti-framing security headers (X-Frame-Options + CSP `frame-ancestors`) with an optional `ALLOWED_FRAME_ANCESTORS` override [#430](https://github.com/THU-MAIC/OpenMAIC/pull/430) (by @YizukiAme)
+- Add i18n key alignment check to CI so missing or extra translation keys fail the build [#447](https://github.com/THU-MAIC/OpenMAIC/pull/447) (by @KanameMadoka520)
+- Add whiteboard layout quality eval harness and unify it with the outline-language harness [#425](https://github.com/THU-MAIC/OpenMAIC/pull/425) [#453](https://github.com/THU-MAIC/OpenMAIC/pull/453)
+
+### Bug Fixes
+

+
+## Claiming Issues
+
+To avoid duplicate effort, please **comment on an issue** to claim it before you start working. A maintainer will assign you.
+
+- If **no PR or meaningful update** (WIP commit, progress comment) appears within **1 day**, the issue may be reassigned to someone else.
+- If you see an issue already assigned, reach out to the assignee first to coordinate — you may be able to collaborate or split the work.
+- If you can no longer work on a claimed issue, please leave a comment so others can pick it up.
+
+## Prerequisites
+
+- [Node.js](https://nodejs.org/) >= 20.9.0
+- [pnpm](https://pnpm.io/) (latest)
+- A copy of `.env.local` — see [`.env.example`](.env.example) for reference
+
+## Getting Started
+
+```bash
+# Clone the repository
+git clone https://github.com/THU-MAIC/OpenMAIC.git
+cd OpenMAIC
+
+# Install dependencies
+pnpm install
+
+# Set up environment variables
+cp .env.example .env.local
+# Edit .env.local with your API keys
+
+# Start the development server
+pnpm dev
+```
+
+## Development Workflow
+
+1. **Fork** the repository and create a branch from `main`:
+   ```bash
+   git checkout -b feat/your-feature main
+   ```
+2. **Branch naming convention:**
+   - `feat/` — new features or enhancements
+   - `fix/` — bug fixes
+   - `docs/` — documentation changes
+3. Make your changes and **test locally**.
+4. Run **all CI checks** before committing (see below).
+5. Open a **Pull Request** against `main`.
+
+## Before You Submit a PR
+
+Run the following checks locally — CI will run them too, but catching issues early saves everyone time:
+
+```bash
+# 1. Format code
+pnpm format
+
+# 2. Lint (with auto-fix)
+pnpm lint --fix
+
+# 3. TypeScript type checking
+npx tsc --noEmit
+```
+
+If formatting or lint auto-fixes produce changes, include them in your commit.
+
+### Local Testing
+
+Before marking a PR as **Ready for Review**, you **must**:
+
+1. **Verify your goal** — confirm that the PR achieves what it set out to do (bug is fixed, feature works as expected, etc.)
+2. **Regression test** — manually check that existing functionality is not broken by your changes (e.g. navigate key flows, verify related features still work)
+3. **Run CI checks locally** (see above)
+
+If you have not completed local verification, keep your PR in **Draft** status. Only move it to Ready for Review once you are confident it works and does not regress other features.
+
+### PR Guidelines
+
+- **Every PR must link to an issue** — use `Closes #123` or `Fixes #456` in the PR description. If no issue exists yet, create one first. PRs without a linked issue will not be reviewed.
+- **Keep PRs focused** — one concern per PR; do not mix unrelated changes
+- **Describe what and why** — fill out the [PR template](.github/pull_request_template.md)
+- **Include screenshots** — for UI changes, show before/after
+- **Ensure CI passes** before requesting review
+- **All UI text must be internationalized (i18n)** — do not hardcode user-facing strings
+
+## Commit Message Convention
+
+We follow [Conventional Commits](https://www.conventionalcommits.org/):
+
+```
+<type>(<scope>): <short description>
+
+[optional body]
+
+[optional footer]
+```
+
+**Types:** `feat`, `fix`, `docs`, `refactor`, `test`, `chore`, `ci`, `perf`, `style`
+
+Examples:
+
+```
+feat(tts): add Azure TTS provider
+fix(whiteboard): prevent canvas from resetting on window resize
+docs: add CONTRIBUTING.md
+```
+
+## AI-Assisted PRs 🤖
+
+PRs built with AI tools (Codex, Claude, Cursor, etc.) are welcome! We just ask for transparency and self-review:
+
+- **Mark it** — note in the PR title or description that the PR is AI-assisted
+- **AI-review your own code first** — before requesting maintainer review, run an AI code review (e.g. Claude, Codex, Copilot) on your changes and address the findings. This is **required** for AI-assisted PRs to avoid dumping large amounts of unreviewed generated code on maintainers.
+- **You are responsible for what you submit** — understand the code, not just the prompt.
+
+AI-assisted PRs are held to the same quality standard as any other PR. Community members are also encouraged to leave constructive feedback on any PR — peer review helps everyone improve.

+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<https://www.gnu.org/licenses/>.

+
+设置后，访客需要输入密码才能使用，所有 API 路由也会受到保护。不设置则无影响。
+
+### Vercel 部署
+
+[![Deploy with Vercel](https://vercel.com/button)](https://vercel.com/new/clone?repository-url=https%3A%2F%2Fgithub.com%2FTHU-MAIC%2FOpenMAIC&envDescription=Configure%20at%20least%20one%20LLM%20provider%20API%20key%20(e.g.%20OPENAI_API_KEY%2C%20ANTHROPIC_API_KEY).%20All%20providers%20are%20optional.&envLink=https%3A%2F%2Fgithub.com%2FTHU-MAIC%2FOpenMAIC%2Fblob%2Fmain%2F.env.example&project-name=openmaic&framework=nextjs)
+
+或者手动部署：
+
+1. Fork 本仓库
+2. 导入到 [Vercel](https://vercel.com/new)
+3. 配置环境变量（至少一个 LLM API Key）
+4. 部署
+
+### Docker 部署
+
+```bash
+cp .env.example .env.local
+# 编辑 .env.local 填入你的 API Key，然后：
+docker compose up --build
+```
+
+### 可选：MinerU（增强文档解析）
+
+[MinerU](https://github.com/opendatalab/MinerU) 提供更强的表格、公式和 OCR 解析能力。你可以使用 [MinerU 官方 API](https://mineru.net/) 或[自行部署](https://opendatalab.github.io/MinerU/quick_start/docker_deployment/)。
+
+在 `.env.local` 中设置 `PDF_MINERU_BASE_URL`（如需认证则同时设置 `PDF_MINERU_API_KEY`）。
+
+### 可选：VoxCPM2（自托管 TTS，支持音色克隆）
+
+[VoxCPM2](https://github.com/OpenBMB/VoxCPM) 是 OpenBMB 开源的 TTS 模型，支持声音克隆。OpenMAIC 自���适配器，把 VoxCPM 跑在自己机器上即可对接。
+
+**1. 部署 VoxCPM 后端。** 三种部署形态，背后是同一套 OpenMAIC 适配器，在设置里切换即可。
+
+| 后端 | 接口 | 适用场景 |
+| --- | --- | --- |
+| **vLLM-Omni** | `/v1/audio/speech` | OpenAI 兼容的语音接口，适合 GPU 服务器 |
+| **Python API** | `/tts/upload` | 官方 VoxCPM Python 运行时（FastAPI） |
+| **Nano-vLLM** | `/generate` | 轻量级 Nano-vLLM FastAPI 部署 |
+
+每种后端的具体启动步骤见 [VoxCPM 仓库](https://github.com/OpenBMB/VoxCPM)。
+
+**2. 在 OpenMAIC 中配置。** 打开 设置 → **语音合成** → **VoxCPM2**，选择后端类型并填入 Base URL，下方的 Request URL 预览会显示实际请求地址。
+
+<img src="assets/voxcpm/voxcpm-connection.png" width="85%" alt="VoxCPM2 连接设置：后端选择、Base URL、模型名" />

+
+```env
+TTS_VOXCPM_BASE_URL=http://localhost:8000/v1
+```
+
+**3. 管理音色。** 三种音色模式，都在 **设置 → 语音合成 → VoxCPM2 → VoxCPM 音色** 里。
+
+<img src="assets/voxcpm/voxcpm-voice-manager.png" width="85%" alt="VoxCPM2 音色管理：Auto / Prompt / Clone 三种模式" />
+
+- **Auto Voice**（默认）：合成时根据每个智能体的人设动态生成 voice prompt，零配置。
+- **Prompt 音色**：用自然语言描述音色，例如 *"温暖的女性教师嗓音，平静而鼓励，中等音调"*。
+- **Clone 音色**：上传一段参考音频或在浏览器里录一段。音频存在 IndexedDB 中，每次合成时发给后端。

+const RUBRIC_PROMPT = `You are evaluating a classroom whiteboard screenshot from an AI teaching assistant. Score like a teacher reviewing their own board work for a student's benefit.
+
+Context: This is a real-time teaching whiteboard, NOT a poster or infographic.
+- Empty space is NORMAL and NOT a problem — teachers write in one area at a time.
+- What matters: would a student be confused, misled, or unable to read the content?
+- Ignore the small dark circle "N" in the corner — it is a page UI element, not whiteboard content.
+
+Score each dimension from 1 to 10 (10 = perfect, 1 = broken):
+
+1. readability — Can a student read every element easily?
+   - Font size CONSISTENCY is critical: penalize heavily if some text is 2x+ larger than other text on the same board (e.g., one giant title + tiny formulas).
+   - Are characters crisp? Any Chinese rendered as boxes or missing glyphs?
+   - Penalize text styled like UI components (gray boxes, card backgrounds) that don't match handwritten whiteboard feel.
+
+2. overlap — Are elements clear of each other, AND does new content respect existing content?
+   - Penalize any occlusion (shapes over text, text stacked on text, arrows piercing labels).
+   - CRITICAL: penalize "writing over existing content" — if a new formula is placed directly on top of an existing table row when empty space was available nearby, that is a layout failure, not just overlap.
+   - 10 = everything distinct; 1 = multiple elements unreadable due to occlusion.
+
+3. rendering_correctness — Are formulas, shapes, and symbols drawn correctly?
+   - LaTeX must render: raw source like "\\\\frac", "\\\\theta", or garbled chunks like "0ext", "Gsinheta", "heta" = major penalty.
+   - Subscripts/superscripts must render: "G_x" shown as raw underscore (not Gₓ) = penalty.
+   - Chinese inside LaTeX math mode (e.g., "口诀(当 a > 0 ext 时)") = penalty.
+   - Diagram ACCURACY matters: a parabola drawn as V-shape straight lines, a circle drawn as ellipse-when-should-be-circle, an angle labeled wrong = penalty.
+   - 10 = all math/shapes render correctly and match the concept; 1 = multiple broken renders OR fundamentally wrong diagrams.
+
+4. content_completeness — Is the content whole, bounded, and annotated?
+   - Edge clipping: any element cut off at canvas edge (formula missing its left character, table column cut, arrow head beyond edge) = major penalty.
+   - Unexpected clearing: if previous turns' content has vanished in a later turn with no reason, penalize.
+   - Bare diagrams with no labels (a circle with no annotation of what it represents) = penalty.
+   - 10 = all content fully visible and annotated; 1 = significant content lost, truncated, or unlabeled.
+
+5. layout_logic — Does the arrangement support teaching flow?
+   - Related elements grouped (a diagram with its labels/formulas together)?
+   - Natural reading order for the concept (cause → effect, equation → graph → solution)?
+   - Spatial planning: does new content go to sensibly-chosen empty areas rather than crammed near or over existing elements?
+
+overall: 1–10 holistic teaching-quality score. Weight overlap and rendering_correctness more heavily since they directly block comprehension.
+
+issues: 1-5 short concrete problem descriptions a teacher would call out.
