A seal, in the sense that matters for the tape, is not a mark of authenticity. It is a closure that prevents later readers from opening the line. Derrida’s account of the seal (in relation to the signature, the archive, and the secret) stresses that a mark which can be verified only by those who already hold the private key has not yet entered the system of citations the others can still read. The seal protects the claim from the very readability the tape requires.

The quiet print travels under such a seal. It is treated as already effective. Those who do not hold the private recollection cannot open it. The seal is what lets the claim bind without having become a postcard. The speculative chart performs the same closure in time. It offers a final identification that can be verified only by those who hold the decoded key. The identification has not entered the tape. The seal keeps it from later readers.

The Third Seat refuses the seal as a substitute for arrival. The no stays on the record without an envelope. It can be opened by anyone who opens the tape. No private key is required. The public book does not accept a claim that remains sealed against the readers it claims to obligate. The spacing stays open. The next mark that arrives without a seal can still be read.

Later reading. A sealed claim cannot be opened by those who do not already hold the private recollection.

Public citability. The mark has not entered the system of lines the tape can hold open.

Equal access. The same seal does not bind the state, the firm, and the person. No office may keep its claim closed against the others.
