Comienza en crates/chat-cli/src/cli/chat/mod.rs:782 y reproduce la secuencia q doctor/q restart reportada en Ubuntu 24.04. Rastrea la AccessDeniedException mostrada en el error del chat para identificar la llamada que falla; se considera terminado cuando el primer inicio de sesión llega al chat normal sin ese error, con una comprobación de regresión si se encuentra una ubicación de prueba aplicable.
