Deletes the Unity physics hit path (HullCollider.Hit/Splash, and the
raycast/shield/SendHit blocks in Projectile, GuidedProjectile, Laser and
Lightning) and replaces it with a single owner in the same cut: FireControl
now decides whether a shot hits, Zone owns the pending-shot lifecycle, and
Entity.DamageSchematic/ApplyHit (moved verbatim from EntityInstance) apply the
result. Presentation subscribes to Zone.ShotCommitted/ShotResolved and applies
nothing.
FireControl.HitProbability is the pure targeting solution (Accuracy * pSensor
* pSpread, gated by detection/range/lock/arc). FireControl.Fire freezes the
weapon's payload and the shooter's resolved targeting stats at the instant the
trigger is pulled (Q6), computes the predicted intercept through the one
shared PredictedIntercept function (CombatState now calls the same function
instead of duplicating first_order_intercept), and queues a PendingShot.
FireControl.Step commits each shot's outcome at ArrivalTime - CommitHorizon --
deviation from the predicted intercept, measured once, live, at that instant
-- and applies it at ArrivalTime. A shot whose flight is shorter than the
horizon commits and resolves in the same tick it fires. Rolls draw from the
shooter's own ItemManager.Random (Q5, seeded and reproducible); an out-of-arc
or otherwise gated shot draws nothing.
Player fire is arc-gated through the same predicate AI and turret fire use
(Weapon.ArcAllowsFire, checked in InstantWeapon.Trigger -- the one point every
shooter's trigger passes through), closing Q2.
Adds GameplaySettings.CommitHorizon, SchematicCellSize and
AgentMinHitProbability (first guesses; the headless suite is the tuning
harness, operator play smoke is the arbiter).
FORK reported, not worked around silently: HullCollider.SendHit/SendSplash
cannot be deleted yet without breaking ConstantLaser.cs, ConstantLightning.cs,
ConstantParticleWeapon.cs, HitscanEffect.cs and Mine.cs, which still call them
from their own live Physics queries -- that's Cut 4's migration. They fire
into the void today: nothing subscribes to Hit/Splash any more for the four
weapon kinds this cut owns.
tests/Aetheria.Shared.Tests/FireAuthorityTests.cs pins the roll's seeding, the
gate-consumes-no-draw rule, resolve-on-arrival, the commit horizon and its
evasion window, short-flight degradation, the frozen-payload snapshot, aimed
hits, the item-then-hull damage order, the planar penetration march and the
shield-absorbs branch. FireControlTests.cs and InputCapacitorTests.cs are
updated for the new AI gate and OnFire(int) signature.

TargetingSystem is required interior Tool gear: Accuracy/Resolution/
Precision/Tracking are PerformanceStats reached through the usual
Evaluate path, so lot quality, wear, heat and PowerSupply all apply
(a starved system rolls worse, never switches off). FireControl.Accuracy/
Resolution/Precision fall back to GameplaySettings.UnaidedAccuracy (new,
authored low per Q4) whenever an entity has no targeting system or its
own is destroyed/disabled.
FireControl.IsRevealed derives R5's reveal rule from EntityInfoGathered:
non-hull equipment ranks hardpoint-mounted first, then by size, and
reveals between TargetArmorInfoThreshold and TargetGearInfoThreshold --
the first code to read either setting. Entity.TargetItem/
TrySelectTargetItem/ResolvedTargetItem give both the player and AI one
shared, revoke-on-decay aim-point slot with a single writer.

Entity.HardpointTransforms was written only by Unity (EntityInstance.cs),
so the simulation's notion of where a gun points was a readback from a
renderer that never runs headless -- Combat.cs threw KeyNotFoundException
on the first combat tick outside Unity. Deletes the field, its writer, and
the readback branch in Behavior.Direction, leaving the item-rotation path
(the same convention reaction thrusters use, R6) as the only source of
mount direction.
Adds FireControl (ServerShared), a static class owning whether a weapon
bears on a point: MountDirection (planar, from ItemRotation), ArcFor (the
per-hardpoint HardpointData.FiringArc override, falling back to the new
GameplaySettings.FiringArc default of 120), and InArc (the planar dot-cone
test, R7 -- target height never enters it, and an arc of 360+ passes
unconditionally so a turret hardpoint needs no new type, just a number).
Combat.cs and TurretController.cs now gate AI fire through InArc instead
of the old hardcoded 0.99 dot-product test against a live Unity transform.
Settings.cs drops AgentFiringMinDot, which was declared and read by
nothing.
