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).

AMineLayerLaysWithTheAimOutsideItsArc: an unfused mine layer passes ArcPermitsFire and lays with the aim outside
its arc. SolveFliesToTheTargetItIsGiven: Solve flies to the decoy it is passed, not the designated target.
ATargetOutOfArcGivesNoSolution also asserts the subject of a designated target out of arc.

Bears is extracted from PFire; ArcPermitsFire passes on a fused gun, a solution, or a free aim in arc.
Solve flies along Solution's direction. ArticulationPoint loses its yaw clamp and follows a per-group
aim point placed from the group's solution. Arcs gets its new brief; Broadside is new.
Unverified: first commit of the cut, not yet built.
