+Project: https://github.com/NanmiCoder/cc-haha
+Commercial licensing: relakkes@gmail.com
+
+This is a custom source-available license, not the MIT License, Apache
+License, Business Source License, or an OSI-approved open-source license.
+The English text in this file is the governing license. LICENSING.md is an
+explanatory guide, not an additional grant or restriction.
+
+1. Scope and existing rights
+
+"Software" means the cc-haha source code and accompanying documentation to
+which the applicable copyright holders apply this license. "Licensor" means
+each copyright holder granting rights under this license, and "you" means
+the individual or legal entity exercising those rights.
+
+This license grants only rights the Licensor is entitled to grant. Third-party
+code, dependencies, and contributions available under a separate license
+remain subject to that license, including their existing notices. See
+THIRD_PARTY_LICENSES.md and any file-level or directory-level license notices.
+This license does not cancel, narrow, or replace rights already granted under
+MIT or another license for previously distributed code. In particular,
+LICENSE-MIT-legacy records the historical MIT terms; it does not grant MIT
+rights to later additions available only under this license.
+
+2. Permitted use
+
+Subject to sections 3 and 4, the Licensor grants you a worldwide,
+non-exclusive, royalty-free copyright license to use, reproduce, study,
+and modify the Software for noncommercial personal use, education,
+research, and the limited internal business use described below. You may
+redistribute the Software and modifications, or provide remote access to
+them, only for noncommercial purposes and subject to section 4.
+
+Internal business use means use within an organization solely for its own
+internal operations, including internal deployments, internal tools, and
+modifications kept for its own internal needs. It does not authorize paid
+client work, developing software or other deliverables for commercial sale
+or licensing, or any other activity reserved under section 3. An employee's
+ordinary salary for otherwise permitted internal work does not by itself
+make that work a prohibited commercial use. Internal deployment or access
+by an employee does not exempt an otherwise prohibited activity.
+
+These terms do not claim ownership of, or require disclosure of, your
+inputs or generated outputs. However, permission to use the Software to
+create outputs remains subject to section 3. Software code copied into an
+output also remains subject to its applicable license.
+
+3. Commercial monetization requires written permission
+
+Except for the limited internal business use expressly permitted in
+section 2, commercial monetization using the Software, its modifications,
+or a substantial portion of it requires a separate written commercial
+license from the applicable rights holders. Without that license, you
+may not:
+
+(a) Sell, license for a fee, rent, or otherwise commercially distribute
+the Software or a product that contains, embeds, or is derived from it.
+
+(b) Provide paid hosting, SaaS, managed services, or remote access to the
+Software or its capabilities to third parties.
+
+(c) Use the Software to perform paid client work or create software or
+other deliverables for commercial sale or licensing, including contracted
+development and commissioned work, whether or not the Software itself is
+included in the delivered work.
+
+(d) Carry out or supply paid customization, secondary development,
+integration, deployment, or maintenance of the Software for third parties,
+or commercially provide the resulting modifications or derivative works.
+
+(e) Monetize a product or service using the Software indirectly through
+advertising, commissions, or bundling with a paid product or service, even
+if access to the Software is described as free.
+
+These restrictions do not depend on whether the product or service competes
+with cc-haha. Keeping attribution, changing names, logos, interfaces, or
+implementation details, or making source code public does not remove them.
+A commercial license is required before carrying out a restricted activity.
+
+Free, noncommercial community forks, redistribution, and remote access
+remain permitted subject to section 4. Voluntary donations solely supporting
+a noncommercial community project's maintenance, without paid access,
+features, or services in return, do not by themselves make it a prohibited
+commercial use.
+
+4. Redistribution and visible attribution
+
+Whenever you distribute the Software or a substantial portion of it, with
+or without modifications, in source or binary form, or provide permitted
+remote access to it, you must:
+
+(a) Include this complete license, the applicable copyright notices, and
+all applicable third-party license notices with the distributed materials.
+For remote access, make them available through a normally accessible legal
+or license page. Do not remove or obscure existing legal or source notices.
+
+(b) Clearly display the following source attribution, with a working link
+where the medium supports links:
+
+    Based on cc-haha: https://github.com/NanmiCoder/cc-haha
+    Copyright (c) 2026 cc-haha
+
+Place it near the beginning of the main README of a source distribution,
+in an ordinarily accessible About or legal page of a graphical application,
+and in the product description or accompanying documentation of a binary
+distribution. For a command-line-only distribution, include it in the normal
+help or license output. For an integrated component, identify the cc-haha
+component in the host product's corresponding notices. It must remain
+legible and must not be hidden behind an additional purchase or login solely
+to view the notice.
+
+(c) If you modify the Software, prominently identify your distribution as
+a modified or unofficial version in its README and corresponding About,
+legal, or CLI notice, and provide a description of your material changes.
+Do not imply that your distribution is an official cc-haha release or is
+endorsed by its maintainers.
+
+(d) Pass these terms to recipients for the covered Software. You may license
+your own additions separately only insofar as doing so does not remove or
+contradict these conditions on the covered Software. This section does not
+require you to publish private modifications or your independently written
+code, and does not grant commercial rights withheld by section 3.
+
+5. Names and marks
+
+No trademark or logo rights are granted except the limited use of the
+cc-haha name needed for truthful source attribution under section 4.
+You may give a modified distribution its own name and branding, but must
+retain the required source attribution and legal notices. This license
+does not require reuse of the cc-haha logo or any minimum amount of code
+modification.
+
+6. Termination
+
+Rights under this license terminate automatically if you violate its
+conditions. If this is your first violation and you fully cure it within
+30 days after receiving written notice from the Licensor, your rights under
+this license are reinstated. Otherwise, reinstatement requires the
+Licensor's written permission. Termination under this license does not
+revoke independently granted rights under MIT or another license.
+
+7. Disclaimer
+
+TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SOFTWARE IS PROVIDED
+"AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT
+LIMITED TO THE WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR
+PURPOSE AND NONINFRINGEMENT. IN NO EVENT SHALL THE LICENSOR OR COPYRIGHT
+HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN
+ACTION OF CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION
+WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE.
+
+All rights not expressly granted under this license are reserved, without
+limiting rights available under a separate license or applicable law.

+也不是 OSI 认可的开源许可证。本页仅解释条款，实际授权以 LICENSE 及适用的独立许可为准。
+
+## 允许与需要授权的用途
+
+| 场景 | 当前许可的处理 |
+| --- | --- |
+| 个人非商业使用、学习、研究、修改 | 允许 |
+| 企业内部自用：内部部署、内部工具、仅供自身内部需要的修改 | 允许；不包括下列需要授权的商业盈利活动 |
+| 员工因正常内部工作领取工资 | 不会仅因此被认定为需要授权的商业盈利活动 |
+| 免费发布非商业社区 fork、修改版或提供非商业远程访问 | 允许，须履行来源署名、许可保留和修改说明要求 |
+| 使用 cc-haha 接单、承接付费委托、开发或交付收费的代码、文档、设计等成果 | 需事先取得书面商业授权，即使交付物不包含 cc-haha 源码 |
+| 使用 cc-haha 开发用于对外商业销售或许可的软件或其他成果 | 需事先取得书面商业授权 |

+| 换皮售卖、收费分发、商业集成或商业再分发 cc-haha 或其衍生版本 | 需事先取得书面商业授权，不以是否构成竞争产品为条件 |
+| 面向第三方提供付费托管、SaaS、托管服务或远程访问 | 需事先取得书面商业授权 |
+| 表面免费，但通过广告、佣金或捆绑收费产品、服务变现 | 同样需事先取得书面商业授权 |
+
+**企业内部自用可用；接单、对外商业盈利、收费修改和二次开发须事先取得书面商业授权。**
+内部部署、员工操作、公开源码或保留署名，均不能豁免上述需要授权的活动。
+限制不以是否与 cc-haha 竞争为条件，不保留“非竞争性商业集成或再分发”的免费例外。
+输入、输出的所有权不会仅因使用工具转移给本项目，但使用工具生成商业交付物仍须遵守上述用途限制；
+直接复制的软件代码还受其适用许可约束。私人修改及独立代码不因此被要求公开。
+仅为非商业社区项目维护提供自愿捐赠、且不换取付费访问、功能或服务，本身不视为需要授权的商业盈利活动。
+商业授权联系：**relakkes@gmail.com**。第三方权利人拥有的部分可能还需另行取得其授权。
+
+## 二次分发必须显著标明来源
+
+对于适用新许可的代码和修改版，应包含完整 LICENSE、版权和第三方许可声明，并展示：
+
+```text
+Based on cc-haha: https://github.com/NanmiCoder/cc-haha
+Copyright (c) 2026 cc-haha
+```
+
+- 源码分发：放在主 README 靠前位置。
+- 图形界面应用：放在正常可访问的“关于”或法律信息页面。
+- 二进制分发：在产品介绍或随包文档中展示，并随包附带许可文件。
+- 纯命令行分发：在正常帮助或许可输出中展示。
+- 远程访问：通过正常可访问的法律或许可页面提供完整声明；嵌入组件在宿主相应位置明确该组件来源。
+- 修改版：明确标记为非官方或修改版，并说明实质性修改，不得暗示官方背书。
+
+这些要求不意味着必须使用 cc-haha 的 Logo，也不要求“修改一定比例的代码”。
+修改名称、界面或大量代码不能自动豁免商业限制和署名义务。
+本许可没有强制公开私人修改或独立编写代码的条款。
+
+## 从 MIT 迁移的边界
+
+1. 此次变更前的主分支提交
+   [`755a18edb7e7519a12f5c7ee4265c9eb4f2ed508`](https://github.com/NanmiCoder/cc-haha/commit/755a18edb7e7519a12f5c7ee4265c9eb4f2ed508)
+   使用 MIT；后续若在迁移前有其他 MIT 提交，也以相应版本实际分发的许可为准。
+2. 旧版 MIT 授权继续有效；已经按 MIT 获得的代码不会因替换根目录 LICENSE 而失去原授权。
+   历史全文原样保存在 [LICENSE-MIT-legacy](LICENSE-MIT-legacy)，该文件不向后续新增代码授予 MIT 权利。
+3. 新许可只在相应权利人有权授权的范围内生效。第三方依赖、内嵌代码、单独授权的文件及既有 MIT 贡献，
+   继续保留适用的许可与通知，参见 [THIRD_PARTY_LICENSES.md](THIRD_PARTY_LICENSES.md) 及文件、目录中的声明。
+4. 本变更不能追溯要求旧版 MIT 使用者在 README 或界面新增署名，也不能阻止其按 MIT 对旧代码进行合规商用。
+   旧版 MIT 原本要求的版权和许可保留义务仍然存在。
+5. 对新增贡献，应在接受前明确贡献者的授权；不能仅靠修改根目录文件宣称取得所有贡献者的版权或重新许可权。
+
+本次迁移没有新增业务代码，不能把已经按 MIT 发布的代码变成只能按新许可使用。
+任何人仍可从历史版本取得这些代码并按 MIT 合规修改、分发和商用。
+新增限制主要作用于未来由有权授权者按新许可发布、且没有其他独立授权的新增内容。
+
+本次迁移仅更新源码仓库的许可文本和说明，不发布新的安装包。
+后续分发适用新许可的安装包时，应随包携带 LICENSE、NOTICE、历史及第三方许可声明，
+并核查上面的可见署名要求；既有发布包不会被本次源码变更自动更新。
+
+## English summary
+
+The governing terms are in [LICENSE](LICENSE). Noncommercial personal,
+educational, and research use, and an organization's own internal operations,
+internal tools, and internal-only modifications are allowed. Ordinary employee
+salary for otherwise permitted internal work is not by itself prohibited.
+
+Separate prior written commercial permission is required for paid client work,
+commissioned development, creating software or other deliverables for commercial
+sale or licensing, paid customization or secondary development, commercial
+integration or redistribution, and paid hosting, SaaS, or managed access.
+These restrictions also cover monetization through advertising, commissions,
+or paid bundles, whether or not the offering competes with cc-haha. They apply
+to paid client work even when the delivered output contains no cc-haha code.
+Internal deployment, employee access, attribution, or public source code does
+not exempt a restricted activity. Output ownership is not transferred, but
+using the Software to create commercial deliverables is still restricted.
+
+Free noncommercial community forks, redistribution, and remote access are allowed
+with the required notices, visible source attribution, and identification of
+material modifications.
+
+Redistributions must carry the license and applicable notices. Source attribution
+belongs near the beginning of the main README, in an accessible About or legal
+page for graphical applications, in binary product descriptions or accompanying
+documentation, and in normal help or license output for CLI-only distributions.
+Private changes and independently written code need not be published.
+
+Existing MIT grants remain valid. The historical MIT text is preserved in
+[LICENSE-MIT-legacy](LICENSE-MIT-legacy) and does not grant MIT rights to later
+additions. Third-party code and separately licensed contributions keep their own
+terms. This is a source-available license, not an OSI-approved open-source license.
+Future contributions must be accepted under clearly agreed terms; this change
+does not transfer contributors' copyright or blanket relicensing authority.
+
+This change adds no product code and cannot make previously MIT-licensed code
+exclusive to the new terms. Historical versions remain available for compliant
+MIT use, modification, redistribution, and commercialization. The new restrictions
+primarily cover future additions that their rights holders release only under
+the new license.
+
+This source-only change does not publish or update installers. Future binary
+releases must carry the applicable license files and meet the attribution
+requirements. Commercial licensing: **relakkes@gmail.com**.
