Read the gaps first. The ring is the orbit, read clockwise from the top, and each mark is one unit at its station. Solid marks are holding alignment, hollow ones are drifting and delivering well under what they were built for, and where a unit came down there is simply nothing on the ring. The gaps are not a rendering choice — that arc has no mirror over it any more, and the domes under it are the ones eating the shortfall.

One line per unit that stayed up, tracked from before the incident to the close of the log. The healthy units dip when the array is disturbed and climb back to roughly where they started. The drifting ones come back part way and then flatten out well short of spec. The flat part is the point: that is a unit that has recovered as much as it is going to.

One dot per unit still in orbit. Alignment error runs left to right, delivered output bottom to top, so a healthy array collects in the upper left: pointed accurately, delivering near rated. Units that lost their footing sit low and to the right, throwing their light past the domes rather than onto them. Units on the surface have no alignment to report and are not plotted.

Two lines and the space between them. Early in the log delivery sits at or above demand and the band is barely visible. After the incident the delivered line drops away and stays down while demand holds roughly where it was, because the crops need what they need regardless. The filled band is the shortfall, and it does not close again inside this log.

Ranked highest to lowest. A unit holding station normally sits in a narrow band near the bottom of the list. The units at the top are spending several times that to stay where they are, and they are the same units the recovery chart shows flattened out below spec. Spend climbs before a unit is written off, so the top of this list is a reasonable guess at which mirrors leave the ring next.

Bars are approaches logged per cycle, with the share that forced an evasive burn marked inside them. The count is low and flat through the early cycles, then steps up and stays up. Wreckage in orbit does not clear itself, so this is the new normal rather than a spike.
