Edit a draft trailer's intent.

What a deck or trailer is FOR. Every deck and trailer is planned from an explicit intent — what the video is for, its logline, theme, central question, stakes, what a first-time viewer is promised, a four-stage arc (setup, escalation, turn, closing question) and how the ending lands the question. Every chapter or beat names the arc stage it serves (arcStage), how it advances the central question (advancesQuestion) and, after the first, why it follows the one before it (whyItFollows: the visible link — a cause, an answer, a contrast, a match cut, a look, an object, a sound — and what it moves forward; one line, never shown on screen). Plan coverage first writes what a first-time viewer would take away from the plan without seeing the intent (viewerTakeaway, with how much of the story the words recited rather than let them work out: toldVersusShown, and where they lost the thread: lostTheThread), then compares it with the intent: intent clarity, the central question, the buildup and whether the theme is carried each fail the plan on their own, and so do subtext — a plan that recites its plot instead of posing its question — and transitions — a part that follows the one before it for no reason a first-time viewer can feel (weakTransitions names the weakest, each with its fix); voices (do the characters speak, rather than the narrator carrying everything) is scored beside them.

Where the units now break the new intent's arc: fix them with the chapter or beat refine.
