An extent read from the first or the last asteroid now fails the belt test (finding s3.belt-fixture-first-read). Builds.

The first fixture hid the big sun's weight in the barycentre (it stood at the origin) and tested reach with two roots only, where nearest and farthest coincide.

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.

One zone node at the massive roots' centre of mass owns the only global term (SubzoneReach is the one place the subzone shape is decided: isolated-subzones). WellNode gains Extent and Anchor; a belt orbit's extent is its outermost asteroid. GravityField.SeriesFrom = 0.4 is emitted into the shader template and Gravity.cginc. Tests: the spec's WellLawTests; the old seam test is replaced by TheBandPotentialIsExactInSinglePrecision. GravityFieldParityVerify runs the multi-root fixture (second sun, moon inside the planet's Roche limit, far window): PASS, largest drawn tau 1.228, max error 0.01028 u. The dotnet suite has not been run at this commit.

Full suite at the previous head: 2003 passed, 1 failed (the seam test, whose 3e-6 was tighter than the closed form's
single-precision floor, 1e-5 measured, 1.5e-5 in the research).

Hand-built zones move from OrbitsFromFieldTests into ZoneWorlds so WellLawTests reuses them. Not yet run.

Gravity.cginc is GravityShader.Source() output. OrbitsFromFieldTests spell periods from GravityField.Pull composed as the law
(binary members feel the partner's pull at the chord, the outer body feels c(total mass)). Fixtures whose bodies carried
mass 0 under constant curves (WellFixture, the mining scenes) now carry a mass: the tree conserves mass. DrawnPoseTests'
rails use the Plummer pull. Builds; not yet run.

GravityField is now the band term U(eps, inner, outer) (C4 smoothstep fade, closed form and a series for tau > 1).
WellTree is built once per Zone from the orbit tree: node terms, reach, support, the pruned Force/Potential walk and
PullAround (rails). Zone.GetHeight/GetForce/PeriodAround delegate to it; WellReference, _wellOn, _strengths,
Strength() and DrawAhead.Well are gone; GravityLowering and the shader template take the flat term list;
HeightExaggeration halves to 2.0491803.
Does not pass yet: Gravity.cginc is not regenerated and PotentialOwnerTests/OrbitsFromFieldTests still spell the old law.

The belt fixture's PlanetSettings lacked AsteroidSize, AsteroidHitpoints and AsteroidRespawnTime, so building the zone
threw before the bound was read. Builds; the previous commit's belt test fails without this.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
A belt's asteroids circle its orbit's parent, so a belt reaches the chain's reach to that orbit plus its Radius
(AsteroidBelt.Radius, the largest asteroid Distance); the chain walk is one function for bodies and belts. The fixture
inserts a smaller body after the outermost so a last-wins bound fails, and a belt beyond the outermost body pins the
belt term. Builds; Unity-side files are in the next commit.

The largest over bodies of the root orbit's offset from the origin, every orbit Distance
along the chain, and the body's Roche limit: a static bound on where any body can be,
computed once at construction and independent of Pack.Radius. Presenters read it.
Builds; the Unity side follows in the next commit.

Each side of a station grows outward from it: a turret sits innerReach + 2 turretReach beyond the body inside it,
so turrets of differing reach clear each other (same arcs as before for one turret hull at k = -1, +1).
StationPlacementTests: shared flank check (no off-ring turret escapes it, 1e-4 relative arc), a narrative
station with five authored turrets and a second, larger turret hull, a zone with no turret hull, and a sweep
that no station or turret reaches another orbital. Not yet run.

The generator picks from every non-rosette planet orbit, empty nodes
included, so the source is the one ring orbit no orbital entity rides.

GameplaySettings carries ShipLayerHeight 3, OrbitalLayerHeight 15, FloaterLayerHeight 0 (authored in Settings.asset).
Entity.LayerHeight (Ship, OrbitalEntity) is the one offset RideHeight adds; DrawAhead.FloaterHeight is the floater
height ItemPickup and MineInstance draw at. HullData.GridOffset (Key 26) and the pickup/mine/prefab GridOffset fields
are gone with every reader. Fixtures (DrawnPose, FireControl*, ImpactFeedback) take heights from the layer owner;
LayerTests pin each kind's layer. FloatingItemsDrawnSmoke follows. ItemPickup/MineInstance.Bind take the settings from
ZoneRenderer. Builds as one commit with its tests; not compile-verified until the cut's head run.

CreateLagrangeOrbit adds one sixth of a turn (was PI / 3 on a turns field).
PlaceTurret spaces turrets by k * (stationReach + 2 * turretReach) arcs,
k = -1, +1, -2, +2 (was t / 2 integer division putting two turrets on the
station, and radians-per-arc arithmetic on turns). Contacts.Radius moves to
HullData.Reach. Not yet verified on Yggdrasil.

Step pairs OfType<Ship>; stations and turrets sit on the orbital layer above the ship plane
(ruling aetheria-gravity:orbitals-above-floaters-below). Tests: a ship flies through a station and a turret;
two ships still bounce beside an orbital. Not yet compile-verified (verified once at the cut's head).

- ActionGameManager: the visible hostile/friendly indicators and MenuMap.Position read DrawAhead.Position at Clock.Lead.
- DrawAhead.Round drops its lead parameter: the target's lead is the drawn time less its zone's step time, derived inside,
so a caller cannot pass two times that disagree. Projectile and BallisticFlightTests updated; the hit tests derive their
lead from the drawn time; two assertions that only varied the now-absent lead are removed.
- Zone.RailAt logs "Requested orbit is not part of this zone!" for a missing parent again (DrawnPoseTests.AMissingParentOrbitIsLoggedAtADrawnTime).
Builds: not yet compiled at this commit (verified by the run that follows).

HUD target, lock, incoming-lock, bearing and sweep markers anchor on DrawAhead.Position / AtBearing at Clock.Lead.
GravityLowering's record fill is DrawAhead.Well (pure, pinned at non-zero lead). Rounds take DrawAhead.Time
instead of float Zone.Time + lead. Sensor ping, shield hit, compass icons, wormhole bearing, loot ViewOrigin and
the guided-projectile aim read the drawn pose. Not built in Unity yet.

GetOrbitPosition's step-time fill and RailAt each decided the rail chain (root at
FixedPosition, child at parent plus offset). The fill is now RailAt(id, _time).
DrawnPoseTests builds the sun on an off-centre FixedPosition (the ZoneGenerator
cluster-root shape) and adds a root test at step and drawn time, and an unset-orbit
OrbitalEntity fact for the DrawAhead guard.
All commits build, unverified until the job in the report.

The co-moving probe projected a world-fixed offset onto the rotating motion
direction; it now compares the planet and ship in world x and z. SimClockTests'
zero-lead sibling at a lead read the step-time ride height; with moving wells the
drawn ride is the field at T.

Planets, belts, wells, loot, mines, stations, the chunk reticle and the flow
clock are evaluated through DrawAhead (Time, Orbit, Height, Position) at one
drawn time; the rail law lives once in Zone.Offset; OrbitPositionAt, GetHeight,
ChunkPose, EvaluateBelt and RideHeight take a time. Fixes the planet jumping
against a co-moving ship at display rates above the step rate.
Not yet built or run (Unity presenter files are verified by compile only on
Starfire).

PeriodAround's ring term is one rule: self feels the mean, over the members whose pull it takes (itself if bodied, else every
bodied ring member), of half the rest of the ring. A station on a binary's ring no longer stands still. The 0.1 u window is a
named constant, pinned just inside and just outside it; a bodyless node's children are pinned never to read the node's parent's well.
Both commits build.

Combat and TurretController spelled GetHeight + GridOffset inline; they call target.RideHeight now. The drawn-ship test authors a hull with GridOffset 2.5 on the well's slope. Two new tests aim at a target hull raised 40 u.

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.

DrawAhead moved xz ahead but carried the last step's y, so on a slope the ship's height stepped once per sim tick.
Entity.RideHeight is the one owner of 'an unparented entity sits on the field'; the step and DrawAhead both call it.
A child is drawn where its parent is drawn.

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.

The crosser is unpiloted and launched at 50 u/s; hull drag slows it to about 25 u/s relative at the bow line.
