Para cualquiera que use redes sociales o servicios digitales, significa menos fallas inesperadas en lo que abre todos los días. Pero el método sigue dependiendo de que una persona revise lo que la máquina propone, y ese control humano es justamente lo que decide si el sistema sirve o no. Un programa que se corrige solo todavía necesita alguien que lo mire.","quienFirma":"Meta","confianza":"divulgacion","consulta":null},"sello":{"hash":"00ccf164756b24bf7ea5fbbddbc63cf464ef00fffd8d7aabc781024eb714a0d5","sello":"55314ad277646c391449b512bc19332a0bf304ec7722b91f1806a9f9415d8106","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6608138,"aleatorio":"8eac64ec62757e2558d5524c58e4b110abaf4c959be2895ca379afc0e66db153","tiempo":"2026-11-03T03:06:00.000Z"},"nist":{"cadena":2,"pulso":2011003,"salida":"21B7B5CCE4EEF61FE5C640A685B3207BC9728D1AB285EB38A7F1A2827293CE9A68AAEFA377CB038730AC32ECF2F2328B5A4B69AF81A1725EA9DA37D047C21178","tiempo":"2026-11-03T03:05:00.000Z"},"noAntes":"2026-11-03T03:06:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Nov  3 03:06:24 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Catching Bugs Before They Land: JiTTesting’s Human-on-the-Loop Approach at Full Scale","descripcion":"Over the last year we’ve been sharing our work leveraging large language models to catch bugs on the fly — a novel approach we call Catching Just-in-Time Tests (JiTTests).
