Castellan accuses President with forensic proof

The Castellan uses the Doctor’s Personal Code Matrix as forensic proof, rendering its pulsing glyph-scape on his console to demonstrate direct temporal tampering. The codes shift when interfaced, visibly linking the Doctor to the lethal manipulation at Talor’s death and the unauthorized access in the computer room.
