Commander Flow

Componentes open-source de terceiros

O Commander Flow é construído sobre software open-source e utiliza modelos de aprendizagem automática locais. Este documento enumera todos os componentes de terceiros distribuídos com a aplicação ou descarregados no seu computador no primeiro arranque, juntamente com a licença ao abrigo da qual são utilizados.

No total são 23 componentes: 17 bibliotecas de software e 5 famílias de modelos ML. Os textos das licenças (MIT, Apache 2.0, CC-BY 4.0, Gemma Terms of Use) figuram uma única vez no final do documento — cada componente está abrangido por exactamente uma delas.

Nota: os textos das licenças abaixo estão reproduzidos em inglês — são os originais oficiais e apenas os originais têm valor jurídico.

Aviso de não-modificação (cumprimento do §4(b) da Apache License 2.0). Todos os componentes licenciados ao abrigo da Apache 2.0 (sherpa-onnx, Serilog e seus sinks, ficheiros de pesos dos modelos Qwen2.5) são distribuídos no Commander Flow sem alterações em relação à respectiva versão upstream. O Licenciante não introduziu alterações ao código-fonte nem aos ficheiros de pesos; por conseguinte, o dever de «prominent notices stating that You changed the files» previsto no §4(b) da Apache License 2.0 não é desencadeado. Quaisquer modificações futuras serão divulgadas no presente documento, com indicação da data e dos ficheiros alterados.

Vozes Piper-VITS (leitura em voz alta, 15 idiomas)

The chat read-aloud feature uses 15 Piper-trained VITS voice models bundled with the installer and loaded at runtime through the same sherpa-onnx engine already listed in §1. The engine is unmodified Apache-2.0; the voice weight files (.onnx) carry per-voice licenses inherited from the underlying training datasets, listed below. No voice was modified by the Licensor.

      "Derivative Works" shall mean any work, whether in Source or Object
      form, that is based on (or derived from) the Work and for which the
      editorial revisions, annotations, elaborations, or other modifications
      represent, as a whole, an original work of authorship. For the purposes
      of this License, Derivative Works shall not include works that remain

      institute patent litigation against any entity (including a
      cross-claim or counterclaim in a lawsuit) alleging that the Work
      or a Contribution incorporated within the Work constitutes direct
      or contributory patent infringement, then any patent licenses
      granted to You under this License for that Work shall terminate
      as of the date such litigation is filed.

   4. Redistribution. You may reproduce and distribute copies of the
      Work or Derivative Works thereof in any medium, with or without
      modifications, and in Source or Object form, provided that You

          Derivative Works a copy of this License; and

      (b) You must cause any modified files to carry prominent notices
          stating that You changed the files; and

      (c) You must retain, in the Source form of any Derivative Works
          that You distribute, all copyright, patent, trademark, and
          attribution notices from the Source form of the Work,
          excluding those notices that do not pertain to any part of
          the Derivative Works; and

      (d) If the Work includes a "NOTICE" text file as part of its
          distribution, then any Derivative Works that You distribute must
          include a readable copy of the attribution notices contained
          within such NOTICE file, excluding those notices that do not
          pertain to any part of the Derivative Works, in at least one
          of the following places: within a NOTICE text file distributed
          as part of the Derivative Works; within the Source form or
          documentation, if provided along with the Derivative Works; or,
          within a display generated by the Derivative Works, if and
          wherever such third-party notices normally appear. The contents
          of the NOTICE file are for informational purposes only and
          do not modify the License. You may add Your own attribution
          notices within Derivative Works that You distribute, alongside
          or as an addendum to the NOTICE text from the Work, provided
          that such additional attribution notices cannot be construed
          as modifying the License.

      You may add Your own copyright statement to Your modifications and
      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with
      the conditions stated in this License.

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for describing the origin of the Work and
      reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each
      Contributor provides its Contributions) on an "AS IS" BASIS,
      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.

3.6 GNU General Public License v3.0 (or later) — Commander Flow TTS Worker (espeak-ng)

Read-aloud of chat answers is performed by a separate program, Commander Flow TTS Worker (tts\CommanderFlow.TtsWorker.exe in the installation folder). The application starts it as its own process and talks to it over a local named pipe using a documented protocol that carries only text in and audio samples out. The worker links the sherpa-onnx speech-synthesis runtime, which is built with the espeak-ng phonemiser compiled in, and every Piper-VITS voice bundle carries espeak-ng phoneme data files. espeak-ng is licensed under the GNU General Public License, version 3 or (at your option) any later version, and the worker as a whole is therefore free software distributed to you under the same license. Full text: https://www.gnu.org/licenses/gpl-3.0.html (also installed as tts\LICENSE; tts\NOTICE.md lists the worker's components).

Complete corresponding source (GPL §6):

The Commander Flow application itself (CommanderFlow.exe and its libraries) contains no espeak-ng code: its own copy of sherpa-onnx (sherpa-onnx-c-api.dll, used for speech recognition) is built from the same v1.12.20 sources with speech synthesis disabled (SHERPA_ONNX_ENABLE_TTS=OFF; see sherpa-onnx-c-api.BUILD-INFO.txt next to it). Nothing in the Commander Flow EULA restricts the rights the GPL grants you in the worker: you may study, modify, rebuild or replace it, and the application keeps working without it (it then reads aloud with the voices installed in Windows).
