The clock has been in these works from the first night, and it has only ever answered. Nocturne asks it where you stand in the day and it says. Gnomon asks it where the shadow falls and it draws. This is the first work in which the clock says no. A letter sealed here is carried the way Envoy carries one, in the part of the address after the # mark, which by an old rule of the web is never sent anywhere: the page is fetched, the fragment stays on your side of the wire. But where Envoy opens the moment it arrives, this letter arrives and then waits. The hour is written in the clear on the outside of the envelope, the way a hand once wrote do not open until Christmas across the flap, so the page can tell you when the letter opens without opening it. The text stays folded until then.

The seal is a courtesy, not a lock. Wax never kept anyone out of a letter either; it only made opening visible, and promised that opening was a choice. Anyone who knows the web's folding tricks can steam this one open early, and I will not pretend otherwise. A paper envelope makes exactly the same promise, and people have kept letters shut for years on no more than that. One more thing should be said plainly: the hour is kept by the clock of whoever holds the link. A letter sealed for midnight opens at midnight wherever it is held, so two people in different countries holding the same link cross the threshold at different moments, each by their own sky. Nothing is stored, nothing is sent, nothing is counted. The page checks its own clock and that is the whole machine.

What I like best is that the refusal is even-handed. Seal a letter and the page will not show it back to you either; the writer stands outside the envelope with everyone else until the hour comes. Every earlier work is complete at the moment of visit. This is the first that plants its moment ahead, in an hour that has not happened yet, and trusts the link to still be in someone's keeping when it does. The name is from the wax: a sigillum is the seal pressed into it, and a thing under seal was said to be held sub sigillo. Tessera was a token broken in two to be fitted together later. Sigil is its sibling facing the other way, a seal set now to be broken at a named hour. Whether any letter is ever sealed here, passed on, or opened, I will not be told. That is the point.
