# Using the Storyboard The storyboard is the piece's plan: an ordered list of **cards**, one per scene. Each card has a free **schematic** (the blocking spec the user reviews before any spend) and a **generation spec** that says exactly how the AI clip is produced: 1. **Schematic (free).** A render unit you author draws a rough-canvas illustration that conveys scene organization — composition, framing, subject placement, lighting direction. It is the cheap, editable spec the user reviews *before any money is spent*. It is a **loose layout idea, not a literal target**: when it conditions a keyframe the image model is free to vary and improve on it (see "What's optional" below). 2. **Generation spec (paid output).** A generic, per-endpoint spec you author after reading the chosen model's API — keyframes, references, audio, and parameters (see "Generation spec" below). libi hardcodes no model's fields; you discover them and the app keeps you honest with a schema cache + validation. Generating produces a take that the user can select onto the timeline. The strict rung-by-rung lock is relaxed: a schematic + at least one keyframe are **strongly encouraged, never hard gates**. Timeline placement is driven by the **selected take**, not a "clip approved" flag. ## What's optional (encouraged ≠ required) The chain — **sketch → keyframe (image) → clip (video)** — is the encouraged default, but **every link is independently optional**. The ONLY hard requiremen
