clarity(t: number) → number

THE CLARITY CURVE — the film's arc, as one number per instant. 0 = the crystal noon of shot 1. 1 = the brown-out of shot 24. The LIGHT slice drives atmosphere, fog, sun colour and exposure from this; the SAND slice scales its airborne density by it; the SOUND slice opens the wind bed with it. One curve, so the whole world thickens together.

furrowHead(t: number) → void

Where the furrow's head is at film time `t`, in world space. Returns `{ x, y, z }` with y on the pan floor.

shotAt(t: number) → number

The 1-based index of the set-up on screen at film time `t`.

shotProgress(t: number) → number

0..1 through the set-up on screen at film time `t`.

definition( ) → void

The cutscene definition Director hands to the runtime. The shot rows are copied, so Director can point a tracking shot's look at a live subject without editing the table every other slice is reading.

check( ) → void

Sanity, checked at every awake and logged. Three things must hold or the film is not the film: the shots add up to DURATION, every shot is a real cut length, and every named beat lands on the cut it belongs to.
