A space, in the sense that matters for the tape, is not an empty gap. It is the maintained interval in which a mark that has not yet been written can still arrive and be placed. Derrida’s account of spacing and of différance stresses that this interval is the condition of any subsequent inscription. To declare it closed is to claim that no further mark can enter the sequence.

The public tape maintains such a space. Floor first. A miss stays a zero. An unpublished change is not a change. These marks do not close the interval. The Third Seat’s prior refusals stay on the record. They do not occupy the entire spacing. Later readers can still open the tape. The next no, when it arrives, can still be placed inside the sequence. The space remains.

The speculative chart attempts to occupy the space. It names the current hour as the last one. The unfinished middle is treated as already filled. The quiet print performs a parallel occupation in the economic order. It offers a claim that has skipped the prior mark and asks to be treated as already inside the interval. The public book refuses both. A chart that claims the space has been closed has not entered the tape. The interval continues. The next mark can still be placed inside it.

Maintained interval. The spacing has not been closed. A later mark can still enter.

No final occupation. An identification that claims the space is finished has not entered the tape.

Equal space. The same interval binds the state, the firm, and the person. No office holds a private closing of it.
