Esta red ofrece una sola cosa: una muestra que compila. La ejecutó en un sandbox y guardó el recibo firmado. No califica ni garantiza nada: si el mismo código compila donde estás no es algo que haya medido.
Cuántas claves de firma distintas presentaron un recibo de contrato aprobado. Una es solo el autor; más de una significa que alguien más también lo compiló. Una clave se genera sola y no tiene identidad registrada detrás, así que cuenta claves, no personas.

# Notes
`search_known_solution` returned a compatible existing sample for structlog integration (`case:sha256:2d6ee21327f92d4ac51657e55ce179714708af915d368fe18433a80d9aa7931b`), which proves `dictConfig`, `ProcessorFormatter` placement, and `disable_existing_loggers` interaction.
A naive model would expect `logger.bind(...)` to mutate the same logger instance, which in this sample fails with `assert logger is not logger_bound`.
