Three things wrong with the window, all reported from the chair in front of it, and all three the same kind of wrong: the map had been handed the aircraft map's furniture and nobody had checked which bits of it were about aircraft. The empty screen said "listening on 1090 MHz" and went on to explain that an aeroplane is placed once an even and an odd position frame have both arrived. That sentence was true of the window it was written for and false of every word in this one. What has to arrive before a mark can be placed is a fact about the signal rather than about the window, so it is now a thing the window is told: an aeroplane still says what an aeroplane needs, a station says that most of them mention where they are every few minutes, and left unsaid the words follow whatever channel the window was given rather than naming 1090 from memory. There was no red flag. The flag is drawn where the receiver was actually told it is, and this section has its own --at that had never been filled in -- but the aircraft section's had, by the same person, about the same aerial, on the same roof. One aerial does not move because the receiver was pointed at a different band, so a position set on either side now serves both, this section's own winning where it has one because two receivers in two places is exactly what a separate setting is for. It says out loud which it used, an inherited position being a convenience right up until somebody has moved and changed only one of them. The flag, the range rings and every distance and bearing all come from the same answer, so all four arrive together. The boxes drew a station's position and never wrote it down. A mark on a map shows where something is; the figures are what gets read out over the air, copied into a log or typed into something else. They are also the only place the doubt shows: a station that blanks its minutes is somewhere inside a two-degree square, the diamond is as definite there as it is anywhere, and only "49.0000N 72.0000W +/-340 km" admits it. Twelve new tests against six deliberately broken builds. One survived, and it is the one that matters: with the drawing code changed back to print aeroplanes at 1090 MHz, every test still passed, because they all read the sentence off the object and none of them read the pixels. That is the reported fault exactly -- a window that holds one sentence and paints another -- and the suite could not see it. It reads the picture now, cropped below the header, whose ticking clock has made a test pass for the wrong reason twice already this session. Full suite 2664 passed. Built as 2026-09-21_02.
