      Signal Wire Topology & Bus Controller State:DAISY CHAINING
      [Bus Controller] ---BG Line---> [Device 1] ---BG Line---> [Device 2] ---BG Line---> [Device 3]
      Common Bus Request Line (BR): HIGH (Asserted)
      Bus Busy Line (BBSY): HIGH (Occupied by Device 2)
      Engineering Tradeoffs:

      Daisy Chaining: Lowest hardware cost (requires only 3 control lines regardless of master count). However, propagation delay is proportional to device count ($O(n)$), and any device failure in the chain breaks grant transmission down the line.
