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.

UnderALookalikeLieNoGearIsLocated: claimed and true hulls of one type and size with a reactor mount of equal type, position and shape. AMountAimReadsThePositionAxesInOrder and TwoMountsOfOneTypeAreTwoRows use a Wing hull off the diagonal with two Sensors mounts. Assert.Same and DoesNotContain over Entities become ReferenceEquals asserts. The docked-stance test reads IsHostileTo on a hostile-by-default subject instead of _iffOverrides. Test-only; no production change. Not yet built.

Conflicts: Behaviors.cs keeps Union(48, PickupData) and Union(49, LaunchSuppressorData);
Zone.cs keeps the departure record on _entities with master's Visibility (emissions-heard);
ContactRevealTests.cs keeps master's removal of the emission-departure test.

Entities is a MemberView with no mutating member; Admit installs the death watch with the
membership and refuses a member already present, Remove takes it away with the membership.
The Reset and duplicate-Add bypass paths of the death watch cannot be spelled any more.
Tests move to Admit/Remove; Admit also activates, so the explicit Activate calls that followed
a raw Add are dropped. Unity call sites route through Zone.Remove.
Builds: unverified at this commit (verified in the job at the head).

SetSignature refuses Emission; Sensor.PingVisibility (key 7) is retired and
Ping() writes no signature; Sense's Emission skip, the departure subtraction
and SignatureOn are deleted. Tests: SetSignatureRefusesEmission,
APingNoLongerBrightensThePinger; fixtures drop PingVisibility.
Not yet built or tested at this commit (verify job follows).

Ship.Update reads Turn and feeds the rotation thrusters and aether drives; it no longer reads the
look direction or snaps Direction toward it. Steering.Toward is the one law from heading to demand
(a heading astern now turns at full demand). HelmInput owns the face-the-aim state. Accelerate,
Combat and MoveTo write Turn through Steering.Toward. Entity.LookDirection is renamed Aim in the
simulation, the Unity readers and the tests. Unity player input follows in the next commit.

Three tests in MiningIndexTests, no production change. RegionsStayNearTheSearchArc bounds the share
of a small search's regions that lie past reach on both sides (window widened, nearest loosened);
VisibilityBoundPrunesADimBelt bounds rocks examined against rocks in reach in a half-lit belt of
largest rocks; ARockExactlyAtReachIsFound searches from 1-300 units with reach set to a rock's exact
distance, a third of them radially outward from a belt's outermost rock. Each threshold's unmutated
and mutant values are in its comment.

BeltTargets drops its own reach skip (TargetRegion.CanHold owns it) and an
empty-belt guard AsteroidBelt already makes unreachable. Tests add an
off-centre sun, whole-belt searches across the antipode, cost after time
passes, a late short step that re-keys nothing, and an entity search off the
origin.
