A minister resigns before the seven o'clock.
The wire lands at 16:47 and the bulletin is at 19:00. You paste the agency copy, choose a ninety-second package, and ask for pictures. Two minutes later you have his statement from the budget hearing in March, the ministry exterior from last week, and an empty slot against the line about the investigation — because there is genuinely nothing in the archive about it. You rewrite that line to something the pictures can carry, and you are in the cutting room by ten past five.
