No newsroom on earth publishes its own bias telemetry in real time. This page is the board auditing itself, every sweep: where today's sourcing actually came from, and which stories are only being told by one side.
verdict this sweep: BALANCED · 48 stories · 62 source placements
The roster is the desk's deliberate spread of outlets (each labeled by public lean indices — labels describe outlet positioning, never story truth). The desk owns the roster file; changing it shows here immediately.
Clear — every multi-source story on the board is carried by more than one side of the spectrum.
Want your own mirror? Your Seat shows Your Tilt — the framing spread of what you've been reading. Private to you, always.
