 The same seven real things as on [zerotrustphysics.com](https://zerotrustphysics.com), and what their edges turned out to be.
 
-- **The SPERT III reactor.** The model takes one step in reactivity between 0.7686 and 1.2102 dollars, the values that the longest and the shortest reactor period of the 1969 tests give. One 64-bit number past either end and the answer stops, naming `ReactivityOutsideCard`. Inside the range there is a place where the burst first reaches 100 MW: at 1.1147492996633026 dollars the peak is 99.9999999999997 MW, and at the next number up it is 100.00000000000001. And a burst is one burst: change the reactivity by one unit in the last place part way through, and the run stops there (`ReactivityChangedDuringBurst`).
-- **NASA's Stardust capsule.** The worked run follows the capsule for twenty seconds from entry interface. Let it run on, and the fall passes 5 MW of heating on each square metre at step 809, passes 10 g at step 849, and is over at step 2,779, 138.95 seconds in, at the drogue-deployment condition the radar recorded. The next step is not taken. Start the capsule 1.73 m/s faster sideways than the flight did and the run stands; at 1.74 it is outside the speeds the compared entry passed through (`AirSpeedOutsideCard`).
-- **The James Webb Space Telescope's guide star.** The model is told where the guide star was measured, frame by frame, and says where it will sit next. Move one measured position by a little over a thousandth of an arcsecond one way, or two thousandths the other, and the run still stands. One 64-bit number further, the star is more than four standard deviations from where it was expected, and the run stops with the sentence that a new one may start no earlier than 30 seconds after that frame (`InnovationBeyondFourSigma`).
-- **Great Britain's power grid.** The model covers the sixty seconds after a power link drops, for a loss between 693 and 1,402 MW. In its worked stumble, a loss of 996 MW, the frequency dips to 49.67 Hz. Make the loss smaller and there is a place where the dip no longer reaches 49.7 Hz: at 869.2003553078027 MW the lowest frequency is 49.699999999999996 Hz, and at the next number down it is 49.7. The minute itself has an edge too: step 2,889 lands, and step 2,890 is not taken.
-- **LAGEOS.** Told where the satellite was at one moment, the model carries it forward seven days and no further: 60,480 steps of ten seconds land, and the 60,481st stops the run, with its proof kept to the last step that landed (`HorizonOutsideCard`). The start has to be the satellite's own orbit. Move the starting position 86 metres along one axis and the run stands; at 87 the orbit is in neither of the two bands the model was compared in (`OrbitOutsideCard`).
-- **A tyre on ice.** The rig measured slip between 0.05 and 0.20, driving or braking, and that is what the model takes: 0.05 stands and 0.049999999999999996 stops (`SlipOutsideCard`). At the worked load the tyre pulls with more than 1,200 N only while the slip is under 0.0682. The worked run sits in the very corner of what was measured, with the slip held 5 seconds before it starts and 21 by its end, so one more step is past the measurements (`HoldBeyondMeasured`).
-- **The power source on NASA's Curiosity rover.** The model follows the generator's daily output from landing to mission day 4,087. Run it a day at a time and the output first reads under 110 W on day 320 and under 100 W on day 1,115. Day 4,087 lands, and day 4,088 is where the model ends (`MissionTimeOutsideCard`).
+- **The SPERT III reactor.** The model takes one step in reactivity between 0.7686 and 1.2102 dollars, the values that the longest and the shortest reactor period of the 1969 tests give. One 64-bit number past either end and, on 0.10.1, the answer stopped, naming `ReactivityOutsideCard`; since 0.11 the model keeps going there with the same equations and flags every step. Inside the range there is a place where the burst first reaches 100 MW: at 1.1147492996633026 dollars the peak is 99.9999999999997 MW, and at the next number up it is 100.00000000000001. And on 0.10.1 a burst was one burst: change the reactivity by one unit in the last place part way through, and the run stopped there (`ReactivityChangedDuringBurst`); since 0.11 a later segment may carry its own reactivity, and the run keeps going with the same equations and flags every step.
