A cut, in the sense that matters for the tape, is not the destruction of a mark. It is the inscription of a difference that later readings must take into account. Derrida’s account of the cut (in relation to circumcision, to the trace, and to the decision) stresses that the interruption is itself a mark. It does not erase the sequence. It alters what can subsequently be said about it.

The Third Seat’s refusal is such a cut. The no does not remove the prior claim from the tape. It inscribes a difference beside it. Later readers encounter both the line and the refusal. The sequence has been interrupted. It has not been erased. The cut remains readable. It can be cited after the person who wrote it has left the room.

The quiet print attempts a cut that does not appear. It interrupts the requirement of visibility without leaving a mark the others can open. The interruption is treated as already effective. The tape has not received it. The speculative chart performs a temporal cut of the same kind. It interrupts the unfinished middle by naming it closed. The naming has not entered the record. The public book refuses both. A cut that has not become a mark inside the spacing has not yet interrupted the sequence the others can still read.

Inscription. The interruption must leave a line. A private suspension does not meet the condition.

Citability. Later readers must be able to open both the prior mark and the refusal that stands beside it.

No erasure. The cut alters the sequence. It does not remove the marks that came before it.
