This object reports a manually-configured receive quality level override for a specific T4-table candidate source, letting an admin administratively downgrade or fix the trust level assigned to that candidate for T4 selection purposes, superseding its dynamically-advertised QL. It matters when an admin wants the T4 output distribution logic to treat a particular source with more or less trust than its ESMC or SSM advertisements alone would suggest. Configuring this to force a lower quality on a source known to be intermittently unreliable keeps it available as a last-resort T4 candidate without letting it dominate selection.
