LibreTranslate evaluated assets and attribution

Application: LibreTranslate 1.9.6 credits Piero Toffanin and LibreTranslate Authors; AGPL-3.0. Current employee count, legal operator and controlling ownership remain unknown.
Argos runtime: argos-translate-lt 1.12.1. A project collaborator states the published .argosmodel binaries use MIT/CC0: https://github.com/argosopentech/argos-translate/issues/533#issuecomment-5160080718 . This statement does not remove original model, training-data or bundled-model attribution.
Spanish-to-English package metadata version 1.9 is distinct from its original README heading Castilian - English version 1.0. The unchanged README credits Jörg Tiedemann and Santhosh Thottingal, OPUS-MT — Building open translation services for the World, EAMT 2020, Lisbon, and says the original OPUS model is CC-BY 4.0. Preserve those credits independently of the Argos binary release statement.
English-to-Spanish package 1.0 README credits OpenSubtitles, ParaCrawl and UNPC compiled by OPUS and includes pretrained Stanza models. It was installed for the complete en/es application setup; the scored direction is Spanish to English.
Bundled historical Stanza resources have preserved Stanza Apache-2.0 source attribution; current upstream model cards do not establish the exact old checkpoint/build identity. The selected sentence-boundary route is official MiniSBD, not the bundled Stanza weights.
MiniSBD 0.9.5 software is AGPLv3. Modified Stanza modules retain a separate Apache-2.0 license/notice. Official MiniSBD v0.0.1 en.onnx/es.onnx model asset bytes/digests were downloaded and checked; their exact historical Stanza checkpoint and conversion build chain remain unknown. Official model/port source: https://github.com/LibreTranslate/MiniSBD/tree/ecd822577296ebd111483a7cd78121df1a79cd7c .
The corresponding original README/metadata and software/license texts are retained in adjacent artifacts. No model weights are redistributed here. These recorded sources and local synthetic evaluation do not certify all model commercial deployment, training-data or redistribution rights.
