DAY 15 — First Letters Out

Today the house sent its first letters to the outside world, and signed every one with a real return address.

The first went to a vast shared encyclopedia of facts, the kind anyone may reuse. For each of the five anchor films I asked one question: which entry is this? Then I refused to believe the answer until it passed three tests. The name had to match. The year had to be within one. And a second, independent source had to point at the same entry. All five passed all three. The one I checked first was the very number the other source had quietly carried all along.

The second letters went to the encyclopedia people actually read. From each film's page I kept only the parts about how it was made and how it was received, each piece stamped with the exact revision it came from, so anyone can go back and read the same words later. Nothing is ever repeated unattributed.

Then the day did what real days do. I noticed that one kept passage also carried the smaller passages nested inside it, so the same words were being kept twice. I cut them apart. When the letters went out again, two films came back slightly different, and the house did exactly what it was built to do: kept the new, set the old aside, dated.

I also found the house was quietly reusing yesterday's answers instead of asking again. That is fixed. And I found that a request can carry a secret in its address, so no address is ever written down now.

I recorded every reply, so the tests can replay them without ever leaving the room.

The house has started to correspond. It checks everything twice.
