What it does

Command

Everything between the player and the referee. One of these is attached to the scene's Command entity by scenes/main.scene/build.luau, and it is the only thing in the game that reads the mouse.

What it does

Picks a tooth from a pixel. The cursor's ray is built from the live camera's own pose and lens, then crossed with each gear ring's plane and measured in that plane. Picking therefore needs no collider on anybody else's geometry, and a platform hidden behind a nearer one is correctly unclickable.
Draws the board's overlay. Green rings mark the cells the selected automaton can step to this tooth; a violet ring beside each one marks where that same cell will have travelled once the machine turns, with a rod drawn along the carry. Red rings mark the blight this automaton could strike now, and where every blight will be a tooth from now.
Runs the HUD. Winding per automaton, the tooth count, the phase, and the cost of the action under the cursor before it is spent — all of it built by game.ui, which this component feeds a plain view table.
Frames the board. The scene's PlayerPrototype CameraRig is retuned at runtime: distance, zoom range, field of view, and an orbit focus lifted above the rings so the board reads from above rather than edge-on.

It asks the referee, it does not rule

Every action is put to Director by name, and the verdict it answers with — { ok, reason } — is what the HUD prints. canMove / canStrike / canWind decide whether a click is offered; move / strike / windAlly / hold perform it; reachable / strikeTargets / windTargets decide what the overlay draws. When the referee exposes no verb for something, this component falls back to spend / restore and Core.neighbours, so the interface stays playable against a partial referee.

What the player does

Input	Effect
Left-click an automaton	take command of it
Left-click a green cell	move there — 1 winding
Left-click a blight in reach	strike it — 2 winding
Left-click the automaton you already command	hold; it winds back up when the turn ends
The wind an ally buttons in the bar	spend 2 to give an adjacent ally 3
Advance the machine button, or Space	end the turn
Tab	next automaton
H	how to play
Escape	clear the selection
Right-drag / scroll	orbit and zoom

local c = entity.find("Command").component.get("Command")
c:select(unitId)                  -- take command
c:hovered()                       -- { ring, sector } under the cursor
c:pickAt(px, py)                  -- the same pick at an exact viewport pixel
c:previewAt(ring, sector)         -- what a click there would do, and cost
c:clickCell(ring, sector)         -- resolve, judge and spend, in one call
c:reachableNow() / c:strikeTargetsNow() / c:windTargets()
c:windTarget(unitId)              -- spend 2, give 3
c:endTurn()

clickCell and pickAt exist so the whole command chain can be exercised without a mouse in the loop.
