65aa61811e Well-law tests follow the subzone law: two suns 600 apart are two subzones, not a superposition
WellsSuperpose is removed (its rule, roots superpose everywhere, is the one multi-root-zone-shape decides); HeightIsThePotentialOverOneK and FlowFieldTests probe inside each well's reach. ZoneWorlds gains Belt and AsteroidSize; fade and ring tolerances are relative to the Plummer pull. Not yet run on dotnet at this commit.

a4977cbe48 Every rail's period is derived from the field it orbits in; OrbitPeriod is deleted
Zone.PeriodAround is the one owner: round a body, the pull its well gives at the rail's distance
(GravityField.Acceleration); round a bodyless node, the ring law (strength of the orbits inside, plus
half of what shares the ring). Orbit.Period and AsteroidBelt.Periods are written once at zone build,
before placement; BeltTargets copies the belt's periods. A parentless orbit has no field and stands at
its phase. Fixtures lose OrbitPeriod and gain wells where their rails must move. Builds; the new
OrbitsFromFieldTests follow in the next commit.

8f491fd3c9 Core radius is the Roche curve; the global exaggeration divides by the core's growth
core-at-roche-and-exaggeration-up: PlanetSettings.CoreRadius and Planet.CoreRadius are
deleted; the well's softened core reads the RocheLimit curve (one curve of mass). The
core < Roche guard cannot fail and is replaced by a Roche-limit-positive-and-finite
check. Settings.asset: CoreRadius removed, HeightExaggeration 10 -> 4.0983607
(10 / (7.32 / 3)). Tests pin the new curves and the peak drawn slope / 2.44x steeper tail.

1c5326dd9d TheCoreIsTheBowlUpToItsEdge: sample 0.996R so a join at 0.995R fails
The mutation table showed a join at 0.995R surviving: no sample lay at or past it. At 0.996R the log form
differs from the bowl by 1.6e-5 c, over the test's tolerance.

45d19f3a8e PotentialOwnerTests: authored curves read from Settings.asset; zero pinned from just below; the core bowl sampled to 0.99R
TheAuthoredCurvesBuildAtEveryMass loads PlanetSettings from the asset the way RunStartTests does. The unphysical-strength
theory adds -1e-6 and -float.Epsilon and a new test builds zero and negative zero. TheCoreIsTheBowlUpToItsEdge compares
the drop from a lone body's centre with c r^2/2R^2 at 0.5R to 0.99R, tightly enough that a join at 0.95R fails.

3a5b3b0bab Gravity grid-lowering: the drawn height is one Gravity Field pass over the zone's wells; gravity brushes and brush inputs deleted
Zone.WellReference owns each body's reference zero (GetHeight uses it). Gravity.cginc mirrors GravityField.Potential;
Brushes/Gravity Field draws depth = -h on layer 9 from a StructuredBuffer that GravityLowering.Lower fills from the
zone each frame; GravityLowering.CreateField makes the one quad. GravityFieldParityVerify renders it and compares every
texel with -Zone.GetHeight (max error 0.0059 u), the gradient with GetForce (0.03 degrees) and the wiring.

Deleted: the Gravity Well children of Planet, Gas Giant, Sun and PlanetOutpost prefabs, Wormhole 1's three gravity
children, their overrides in Main Menu and TestScene, five wormhole/wave materials and two brush shaders,
Planet.GravityWellDepth/Radius, BodyData keys 6-7, PlanetSettings.GravityDepth/GravityRadius (and the Settings.asset
keys). Surface Displacement culls layer 9 only. Headless build and tests not yet run at this commit.

c4dfd905ff Gravity: the Planet guard refuses an unphysical well; tests pin the Roche rule, per-body multipliers, the core band and Ship's order
A WellStrength that evaluates negative, NaN or infinite now throws at construction (it built an
antimass well with NaN height). New tests: the core-inside-Roche guard judged at every mass on
curves that cross in the generated range; per-body multipliers move neither strength, core nor
Roche limit; potential and force consistency inside the cores' outer bands (0.5 R to R); a
moving Ship feels the field where it has moved to.

021c4cbcbf Gravity: one potential per zone owns acceleration and height
GravityField is the law of one well (logarithmic tail, softened core).
Zone.GetForce and GetHeight sum it over the bodies; GetNormal derives from
the force for ship tilt; Flow and Ship read GetForce. Well strength, core
radius and Roche limit are PlanetSettings curves of mass, height
exaggeration K one global. Deletes GravityAcceleration, GravityReferenceRate,
GravityStrength, the PowerPulse well, GetNormal's finite differences and
BodyData.GravityDepthExponent. Settings.asset carries the calibrated curves.
Tests: PotentialOwnerTests, the moon's moon placement, retired keys over every
BodyData type, a body-derived giant sweep. Not yet built or run (verify job
follows); this commit may not build.
