Rook-7 (Robot)

Rook-7 did not log audio on the gallery. The wind's noise floor sat above the threshold at which its intake could resolve anything worth carrying, and a log entry that recorded only that a microphone had been overwhelmed was an entry about the microphone. It logged the other channels instead, and it counted.

Two flashes, then dark, then two flashes, then dark. Fifteen seconds, group to group. It counted four hundred and six groups against its own clock while the humans were still on the stair, holding to the rail on the seaward side where the gallery narrowed, and the character was correct to within the tolerance the register required and correct to nothing tighter than that, which was itself the finding: the light was accurate to the standard it was inspected against, and the standard it was inspected against had been set by people who had never needed it to be accurate to anything else.

Observation: the register is complete. Completeness is not a property the Board required, specified, or inspected for. It is a by-product of a maintenance obligation that happens to have been discharged in writing for two hundred and seventeen years by people who were not being asked anything. Flag: the survey's search of the archive was a search of records created to answer questions. This record was not.

Rook-7 held that entry unsent, which it did with roughly one entry in forty, and appended a second line to the same block.

It had asked the attendant one question, on the stair, in the interval when the door below was shut and speech was available. Nothing on the water had navigated by the Sceir Light in a very long time — the traffic that used this shore carried its own solutions and had for generations, and the Board's own register recorded the light's fixes as a formality against instrument failure that had not been invoked in Rook-7's lifetime or the attendant's. It had asked why the light was still lit.

"Because it's lit," Beirne had said, on a stair, in the dark, with the note in the glass coming down past both of them. "That's the whole of it. A light you only put on when you know someone's out there isn't a light. It's a favour."

Rook-7 logged the sentence verbatim and filed it under nothing, there being no category in its schema that the sentence belonged to, and followed the humans down.

Below, on the spit, the falling tide had another fifty minutes in it and the wind had not eased at all.
