#[Deprecated] on a constant, and the notice nobody saw

A deprecated class constant emitting a notice on every use, into a channel that had been discarding notices since a configuration change in March.

final class Order
{
    #[Deprecated(message: 'use Status::Pending', since: '5.2')]
    public const string STATUS_PENDING = 'pending';
}

// and config/logging.php, changed to reduce noise
'deprecations' => ['channel' => null],

The same mistake as 2023 and in a smaller way: a channel set to null during a noisy week and never restored. The deprecation mechanism is only as useful as the destination, and the check that catches it is a test asserting the deprecation channel is not null — four lines, and it now runs with everything else.
