Acompanhante da ferramenta de c\u00f3digo aberto ScanCode Toolkit, destinada a escanear o c\u00f3digo em busca de viola\u00e7\u00f5es de direitos autorais de terceiros, identifica\u00e7\u00e3o das licen\u00e7as utilizadas e descoberta de vulnerabilidades n\u00e3o corrigidas, criticou o projeto que criou um clone do produto ScanCode com a ajuda de IA, reescrito de Python para Rust (o nome do clone n\u00e3o \u00e9 mencionado, mas, pela apar\u00eancia, refere-se ao projeto Provenant). Afirma-se que o projeto reescrito infringiu a marca registrada ScanCode e removeu refer\u00eancias a direitos autorais e licen\u00e7as. As reivindica\u00e7\u00f5es s\u00e3o justificadas pelo fato de que no clone reescrito foram mantidos algoritmos-chave do ScanCode, preservada a arquitetura do projeto e a estrutura do c\u00f3digo. <\/p>\n

Na opini\u00e3o do acompanhante do ScanCode, a cria\u00e7\u00e3o bem-sucedida do clone foi facilitada pela exist\u00eancia de um conjunto abrangente de testes automatizados do projeto, que inclui mais de 90 mil testes, dos quais 40 mil se dedicam \u00e0 detec\u00e7\u00e3o do uso de v\u00e1rias licen\u00e7as no c\u00f3digo. Os autores da vers\u00e3o reescrita afirmaram ter alcan\u00e7ado um aumento significativo de desempenho (10 a 100 vezes), mas, segundo o acompanhante do ScanCode, o pre\u00e7o da acelera\u00e7\u00e3o foi a n\u00e3o-completude na execu\u00e7\u00e3o do conjunto de testes, al\u00e9m da redu\u00e7\u00e3o na precis\u00e3o e na plenitude das informa\u00e7\u00f5es fornecidas (o clone apresentava resultados incorretos e n\u00e3o encontrava todas as informa\u00e7\u00f5es durante a an\u00e1lise). <\/p>\n

Se em testes de desempenho especiais o port do Rust superou significativamente o ScanCode, ao passar pelo conjunto de testes padr\u00e3o, o clone se mostrou mais lento, apesar de que algumas verifica\u00e7\u00f5es foram puladas. Ap\u00f3s a implementa\u00e7\u00e3o de otimiza\u00e7\u00f5es no ScanCode, como cache, o desempenho do ScanCode ao escanear o c\u00f3digo se tornou t\u00e3o bom quanto o do clone em Rust, mantendo a precis\u00e3o do funcionamento.<\/p>\n

Os autores do clone tamb\u00e9m s\u00e3o considerados respons\u00e1veis por violar os direitos autorais e a licen\u00e7a Apache 2.0 sob a qual o c\u00f3digo do ScanCode \u00e9 distribu\u00eddo. Observa-se que, no processo de reescrita, quatro requisitos principais da licen\u00e7a foram violados: deixar o arquivo original com a anota\u00e7\u00e3o (NOTICE), manter as men\u00e7\u00f5es aos direitos autorais, destacar as altera\u00e7\u00f5es feitas e mudar o nome na obra derivada. Ap\u00f3s o aviso, os autores do clone publicaram o arquivo NOTICE e renomearam seu projeto, mas duas das outras viola\u00e7\u00f5es ainda permanecem n\u00e3o corrigidas.<\/p>\n

O respons\u00e1vel pelo ScanCode acredita que a comunidade deve desenvolver crit\u00e9rios para distinguir entre o que, ao usar IA, deve ser considerado uma obra derivada e o que \u00e9 uma implementa\u00e7\u00e3o independente. Na sua opini\u00e3o, ap\u00f3s reescrever o c\u00f3digo em outra linguagem mantendo os algoritmos e a estrutura, o resultado continua a ser uma obra derivada, mesmo que durante o processo as vari\u00e1veis tenham sido renomeadas e coment\u00e1rios tenham sido modificados ou removidos. As alega\u00e7\u00f5es dos autores do porto Rust de uma reestrutura\u00e7\u00e3o independente, apenas inspirada no projeto ScanCode, s\u00e3o incorretas neste caso, pois o trabalho visa criar a apar\u00eancia de um desenvolvimento original, o que \u00e9 ainda pior do que a c\u00f3pia direta, j\u00e1 que tais manipula\u00e7\u00f5es s\u00e3o mais dif\u00edceis de detectar. <\/p>\n

Um problema significativo na gera\u00e7\u00e3o de c\u00f3digo atrav\u00e9s de IA \u00e9 a aus\u00eancia de rastreamento da origem do c\u00f3digo que foi utilizado para obter o resultado. Por padr\u00e3o, agentes de IA que utilizam c\u00f3digo de projetos abertos ignoram informa\u00e7\u00f5es sobre os autores, a menos que sejam implementados recursos espec\u00edficos para identifica\u00e7\u00e3o e preserva\u00e7\u00e3o de metadados sobre licen\u00e7as e autoria. O problema da atribui\u00e7\u00e3o afeta n\u00e3o apenas a reescrita de c\u00f3digo de uma linguagem para outra, mas tamb\u00e9m a gera\u00e7\u00e3o de c\u00f3digo de forma geral \u2014 o resultado, nesse caso, pode reproduzir com bastante precis\u00e3o os padr\u00f5es de c\u00f3digo aberto existente utilizado no treinamento do modelo.
