# Coverage

Every model the verifier serves, each stop its own description names, and whether a row of this dataset brackets it. A stop is **covered** when a row holds the last request that stands and the nearest one past it. It is **not reachable from the worked example** when no change of one number in the model's own worked example met it next to a request that stands. It is **not attempted** when a change of shape reaches it (a word, the length of a list, a load changed by a visible amount part way, a run continued from another), where there is no pair of numbers either side.

Stops named in a model's description were read from the address on the date the rows carry. The first seven models are the seven on https://zerotrustphysics.com.

In all: 936 rows; 255 named stops covered, 401 not reachable from the worked example, 25 not attempted.

Left out of the rows on purpose: stops that belong to the form of a request and not to a model (a number that is not a finite normal 64-bit number, a count of steps below 1 or above 1,000,000, more than 10,000 recorded frames).

## `aerospace/capsule_stardust`

The Stardust sample return capsule on its entry of 15 January 2006, from entry interface down to the drogue-deployment condition the radar recorded, under 31030 m and under Mach 1.23 at once, past which a state is refused: no lift, no wind, a yearly standard atmosphere, and no load. One entry was compared with the flight, the locked entry from entry interface; off that path the card holds the limits each field states.

## `aerospace/los_jwst_fine_guide`

The line of sight of the James Webb Space Telescope in quiet fine guide, as its Fine Guidance Sensor reads it every 64 ms: a Kalman filter stepped through the flight centroids of one fine-guide file, with eighteen constants fitted to this observatory's own centroids of April 2022. On quiet frames of held-back visits it met its five marks. It was compared on quiet fine guide only: on engine 0.10.1 a centroid more than 5 mas from the lock point, or more than four stated standard deviations from where it was expected, was refused and ended the run, and a new run started no earlier than 30 s later; since 0.11 the model answers those frames with the same equations and flags them.

## `energy/grid_gb`

The Great Britain synchronous area, the 50 Hz transmission system of England, Scotland and Wales as one rotating mass, in the 60 seconds after an importing interconnector trips. It is the served model of that event at any date: on trips from mid-2018 to early 2025 it met its lines, and on the six compared trips since November 2025 its fall is 39 to 80 percent deeper than the measured fall.

## `energy/generator_mmrtg_f1`

One radioisotope generator, flight unit F1, on the Curiosity rover: its daily-average electrical output from landing to mission day 4,087, with no load; on the 1,279 held-back days, 2,809 to 4,087, it was inside its line of 0.010 of 115.4 W by root mean square (0.008129, about 0.94 W) and outside it in its mean over the final 365 days (+0.010094, about 1.16 W high), so it failed its comparison by the rule fixed beforehand and is served with that stated. Its worst day read 2.60 W high.

## `energy/accumulator_sbo450`

The nitrogen charge of one HYDAC SBO450-0.6 diaphragm accumulator on the test rig at TU Darmstadt, as a piston pushes oil in and draws it out: gas pressure, temperature and an energy ledger. The ratio of piston area to vessel volume and the thermal time constant are fitted to this accumulator's own runs at 40 bar precharge and 60 bar. Compared with 285 held-back runs at 40, 80 and 120 bar and at half the charge, 0.01 to 20 Hz: the comparison failed, two of six lines met, and a second scoring confirmed it. Amended after that with every run opened, which is not a new test: on engine 0.10.1 the card refused by name outside the range in which it held: a precharge of 20 bar at gas pressures of 37 to 43 or 55 to 67 bar, or of 40 bar at 57 to 64 or 75 to 86 bar, the bands in which each charge was measured, a wall at 293.4 to 293.7 K, gas at 285.9 to 301.8 K and a piston at most 0.7 m/s, as in the measured runs, and heat at most 0.065 of the work over the whole motion, which in the measured sines is 0.2 Hz and faster; since 0.11 a step outside that range keeps going with the same equations and is flagged, up to the vessel's rated 330 bar, and heat above 0.065 of the work is still refused. Run after the fact on 0.10.1 it answered 196 of those 285 runs and refused 89; on the 196 the swing of gas pressure per piston travel is within 0.49 percent in the median, 1.37 in the worst record and 4.05 at most.

## `aerospace/capsule_insight`

The InSight entry capsule on its entry at Mars of 26 November 2018, from the top of the atmosphere to just past the flight's parachute deployment, down to 5700 m or Mach 1.46: no wind, the air of orbiter soundings set on the lander's barometer, and the capsule's lift as the load. Only runs from the locked entry state were compared with the flight; on engine 0.10.1 only states on the corridor they flew were answered, and since 0.11 other starts keep going with the same equations, down to the landing site, and are flagged. It does not forecast an entry whose lift is not known.

## `materials/creep_cmsx6`

One cast of the single-crystal nickel alloy CMSX-6, loaded along [001] at 980 degrees Celsius, creeping in tension under a held load: the percentage creep extension of a round test piece 6 mm in diameter against the time since the full load, from 0.1 percent to 5 percent at 170 to 230 MPa and from 0.1 to 0.2 percent at 140 to under 170 MPa. Six constants fitted to six creep tests of this cast; the time to a level met its three lines on six held-back tests. Below 0.1 percent, and past 0.2 percent under 170 MPa, the law misses the measured curves; there the card refused on engine 0.10.1, and since 0.11 it answers with those misses stated and flags every step.

## `materials/fingerpad_p02_glass`

One human finger pad pressed on flat glass at 2 N (1.93 to 2.07 N) and twisted about the normal at 5 to 50 degrees a second until it slips, the right index finger of participant P02 of the torsion experiment at UCLouvain: the torque, the stuck fraction of the contact, the work and the heat, from eight constants fitted to this finger's own trials. Compared on 2026-10-09 with its held-back trials at 1 N, 10 N and 100 degrees a second and missed: the slip torque was off by +9, +29 and -13 percent against a mark of 5.6 percent; on engine 0.10.1 those conditions and every other load were refused by name, and since 0.11 it answers at every force and rate above zero with those misses stated and flags every step where nothing was measured. What was left on 0.10.1 was the one block of trials the fit took its level from: there this finger slipped at 10 to 11 N mm and the card gives that to about 8 percent, on trials it was fitted to, which is not a test. Another block of the same finger differs by 13 to 15 percent, another finger by about a fifth.

## `energy/reactor_triga_jsi`

The TRIGA Mark II reactor of the Jozef Stefan Institute, Ljubljana, with its 56-element core of standard fuel, in pulse mode from 2.0 to 3.0 printed dollars on the rod-worth tables of cores 215, 217 and 231: power, energy released and core-average fuel temperature from the fire signal through the pulse to the scram. Ten constants are fitted to 36 pulses of this reactor, in a form added after the twelve fixed beforehand had failed; by the rule fixed beforehand the comparison with the 20 rows held back failed, four of six lines missed, with peak power 23 and 44 percent low on a day the card was not fitted to; the fuel temperature was compared only through one thermocouple of one element. After that scoring the lower limit was raised from 1.4 to 2.0 dollars, where the held-back rows had read up to 29 percent low: below 2.0 dollars the card refused by name on engine 0.10.1, and since 0.11 it computes the same equations there, with nothing compared, and flags every step.

## `argon_pair_gas`

Argon gas at low density from one Lennard-Jones pair potential whose two constants are fitted to the measured speed of sound in argon: second virial coefficient, speed of sound and viscosity at zero density. On engine 0.10.1 each property was answered where it was compared: the speed of sound from 250 K to 349.868 K at 30.5 kPa to 467.2 kPa, the viscosity from 291.09 K to 681.96 K at zero pressure; elsewhere the solver refused by name. Since 0.11 it keeps going past that with the same equations, from 250 K to 6000 K, where argon begins to ionize, at 0 to 500 kPa.

VTT D-221704 in an ambr 250 vessel at pH 4.0 and 35 °C, turning D-galacturonate into mucic acid: biomass, glucose, galacturonate, mucic acid, carbon dioxide made and oxygen taken up at the end of every segment of the caller's feeding record, with carbon and electrons closed; six constants are fitted to this organism's own measurements, at a feed of 29.4 to 34.7 g/L glucose; on four held-back cultures fed 10 and 50 g/L it met three of its six lines and missed three (galacturonate, mucic acid and carbon dioxide), a second scoring confirmed it, and it is not validated against measurement. On engine 0.10.1 it refused by name a feed outside the fitted 29.375 to 34.676 g/L glucose and a record longer than 215 h, so the four held-back questions were refused, and, from 0.7.0, a starting biomass, glucose or galacturonate, a feed schedule, water, sample or broth volume outside the fitted cultures' own. Since 0.11 it answers any start, feed and feed schedule from zero, the four held-back questions among them, held only by its own limits.

## `fusion_pb11_lhd`

Proton-boron-11 fusion in the boron-seeded hydrogen plasma of the Large Helical Device under one hydrogen neutral beam of 45 keV or of 127.45 to 160.25 keV: alpha particles per second, fusion power, the share of beam protons that fuse, and the alpha emissivity profile. No constant is fitted. On engine 0.10.1 it answered only inside the envelope of the inputs compared with measured alpha count rates, each beam family inside its own, and refused outside it by name; since 0.11 it keeps going with the same equations, for a beam above the 10 keV stopping energy to 190 keV, and stops only at a physical limit, and says why. Compared with one published calculation and, in shape only, with measured alpha count rates: it missed three of its four pass lines. It is not validated against measurement.

## `fusion_pb11_thermal`

Energy balance of a uniform thermal proton-boron-11 plasma, ion temperature 200 to 450 keV: the electron temperature at which the electrons balance, fusion, bremsstrahlung, synchrotron and exchange power, and the ignition margin. No constant is fitted. No such plasma has been made: it is checked against published calculations only, on engine 0.10.1 it answered only inside the inputs of that comparison, and since 0.11 at ion temperatures of 1 to 1000 keV, where the balance's own forms hold, and of its eight gated pass lines seven were met and one was missed.

## `pipe_flow_superpipe`

Fully developed, smooth-wall, turbulent air flow in the Princeton Superpipe (129.36 mm bore), a mixing length with van Driest damping with nothing fitted (kappa 0.41, A+ 26): Darcy friction factor, centreline-to-bulk velocity ratio and the mean velocity profile, bulk Reynolds number 31,577 to 35,724,000 on engine 0.10.1 (since 0.11, 4000 to 1e10 and bulk Mach number up to 0.3), laminar, transitional and rough-wall flow refused by name; compared once with held-back Superpipe measurements of A. J. Smits' group: the friction line met (rms 1.38 percent, worst 2.69, against Prandtl-Karman's 2.17 rms) and the profile line met (1.59 percent), the centreline line missed at one of 21 profiles (2.99 percent low against 2 percent, the NSTAP profile at 81,330), so by the rule fixed beforehand the comparison failed; the friction factor falls below the measured one as the Reynolds number rises, 2.7 percent low at 35.7 million.

## `step_flow_armaly`

Steady laminar air flow over the backward-facing step of the rig of Armaly and others (1983; step 4.9 mm, channel 5.2 mm opening to 10.1 mm), two-dimensional Navier-Stokes with nothing fitted: reattachment length and the velocity profile at one station, Reynolds number 100 to 389; compared with measured velocity profiles at 100 and at 389 only, second-hand and digitised, all three lines met at 389 and confirmed by a second scoring, and at 100 also first-hand from Armaly's Figure 15 out to 30.31 step heights; stations out to 30 step heights at 100, out to 13.57 above 100; the reattachment length at 100 is 14 percent below the sentence of NASA Technical Memorandum 106248 that quotes the measurement, a miss of that sentence, and 6 percent below Armaly's own plot as read first-hand afterwards, inside the mark; at 389 it is 6 to 7 percent below that plot.

## `tokamak_dt_beam_target`

The deuterium-tritium fusion rate of one time slice of a JET or TFTR pulse in steady state, from its analysed profiles (temperatures, densities, fuel mix in up to 128 radial shells) and its neutral beams: thermal, beam-target from classical slowing-down with the Bosch-Hale cross-section, and beam-beam reactions, the fusion power and the neutron rate. No constant is fitted. Its held-back comparison failed: on the 34 slices of every TFTR tritium pulse of the profile database, another machine, the median of solver over database fusion power was 1.02, but 30 of the 34 lay inside 0.75 to 1.25 where nine in ten were asked (second scoring V-42: the same numbers). The reference is TRANSP's calculation on the same profiles and beam heating the solver is given, so agreement shows the solver's slowing-down arithmetic matches TRANSP's on TRANSP's own plasma and nothing about the neutron counters; against four measured values the solver is +7, +21, -11 and about +8 percent. After that failure limits were written in, on data by then spent and so tested blind by nothing, and are enforced by name. Since engine 0.7.0 the fast ions the solver finds are counted in each shell's charge balance and held from both sides at the extremes the slices compared and answered reach (no more than 12 percent over or 21.5 percent under the electrons), and on engine 0.10.1 the ranges of the physics were the span of those slices; since 0.11 it answers ion temperatures of 0.2 to 100 keV and beams to 1000 keV. The band is wide, and that is a finding: on TFTR the solver's own fast ions are 1.1 to 3.1 times the database's in the shell of largest excess, and the questions carry no thermal hydrogen, which TRANSP holds at 4 to 22 percent of the electrons at the edge. Of the 34 TFTR slices, 23 are answered on 0.7.0 as on 0.6.0, with the same bits: median 1.088, 21 of 23 inside 0.75 to 1.25 (1.015 and 23 of 23 with pulse 73268 against five times its database value, an alpha power). On JET the same 53 slices are answered, median 0.934, all inside the band.
