August 2150. Monthly calibration. Non-random pattern in the layer at the junction boundary, narrow band, 2.4 to 2.9 terahertz. Ran the diagnostic three times before carrying it across the room — the tier eight went in four months ago and I trust it less than I will. The intervals are mathematical. Margin: the tier six read this as noise for eight years. It was not noise. It was under the noise.
Later, same page. It has been there the whole time. Possibly years. We were not detecting an arrival. We were detecting that our eyes finally got good enough.
2151. Eighteen months of watching, mapped. Prime structure; the escalation in the long sequences is clean in a way nothing thermal is. He has built a bootstrap and sent it. Margin: now the part where the method has to be enough, because nothing else is coming to help it.
Month fifteen, day twelve. Tomas still checks. I don’t know that I would.
2153. Response. It came in on the rotation we sent that morning, six hours after — seven lines, prime structure kept, and two operators we never gave it. Derivable from the grammar, but only by something that understood what the grammar was for. Margin: not an echo. Logged it with my hands steady, which took doing.
2154. Sixteen days of nothing, the longest yet. He said the word artefact today — a standing wave, five years of pattern-hunger reading structure into a boundary layer. I told him across the racks that I would log that conclusion the day he can explain the prime structure as physics, and not before. He could not, and he stopped saying it. Margin: the thing in the layer is not always speaking. It is always there. The distinction is the whole discipline.
2155. Every three or four days now. Slower this fortnight. It varies. Margin: every few months in ‘53. Every few weeks in ‘54. It is developing carefully, and so are we, and only one of us gets to decide the pace.
