# Godfortune Visual Split Quality Loop

Video research is separated in the same way that accompaniment, singing, and the
final music mix were separated. A single generated frame is not used to diagnose
background, character, compositing, and motion at once.

## Gate Order

1. Generate and approve four clean background plates per qualification scene.
2. Generate and approve transparent character states independently.
3. Build deterministic composite keyframes from approved layers.
4. Compare layered 2D, Wan I2V, and a hybrid treatment from the same composite.
5. Select the winning treatment per shot instead of forcing one engine across the
   complete episode.

## Background Plate

The background contains no people, characters, text, logo, or watermark. It is
scored for coherent geometry, scene-specific props, art direction, character and
caption safe zones, compatibility with the character line and palette, and
artifact absence. The previous three background candidates remain rejected
evidence and are not motion inputs.

## Character State

Each recurring character is delivered as a transparent full-body layer with
canonical anchors and a separate contact shadow. Required states are neutral,
speaking, singing open, gesture contact, extreme reaction, and recovery. Identity,
expression, silhouette, proportion, edge quality, and artifacts are evaluated
without a generated background.

## Composite Keyframe

Approved layers are assembled deterministically. Generative repaint is prohibited
after identity approval because it can change the face, clothing, or proportions.
The composite gate owns scale, staging, grounding, shadows, occlusion, mobile
readability, and caption safe zones.

## Motion Treatment

Dialogue defaults to layered 2D because it preserves identity and allows exact
audio timing. Wan I2V competes only for short exaggerated reactions, musical
climax gestures, and transitions. The hybrid candidate keeps the approved
character and background layers for most frames and uses I2V only where it
produces a measurable improvement.

Every gate requires a total score of at least 90, its metric floors, no hard
failure, and human approval. Background and character scores are never averaged
to hide a failed component.
