## Source Basis

- `intake/阶段五-镜头清单骨架.md`: S-45, lyric "别回头"; back view passes old footprints without looking back.
- `slides/slides.md`: closure into "continue"; style A / motif.
- `visual-system/visual-system.md`
- `visual-system/style/style-prompt-master.md`
- `visual-system/characters/character-reference-registry.md`

## Slide Function

Compress farewell into a physical action: old footprints remain behind; the traveler continues.

## First Read

Muddy footprints and old road trace first; back-view traveler moving past them second.

## Risk Class

medium/distant human, motif detail

## Reference Plan

- Style module: A Landscape-Led Road.
- Active style reference: `projects/2026-06-23-在路上/intake/imgs/A.风景主导型蓝图.png`
- Character reference: `projects/2026-06-23-在路上/visual-system/characters/character-slice-walk-back-v2-from-anchor.png`
- Visible-context roles for generation: Image 1 A road reference, Image 2 walking back identity reference.

## Visual Requirements

- Back view from behind the traveler.
- Old footprints visible in wet mud behind or beside him.
- He does not turn back.
- Frame leads into the coming C reveal; keep mud real.

## Character Handling

Use walking back slice for posture, coat/backpack silhouette, boots, and no-looking-back direction.

## Composition / Scale

Medium-wide or wide 16:9 frame. Footprints occupy foreground/midground; traveler about 1/10 to 1/7 of frame.

## Light / Color / Texture

Cold dark road or pre-dawn, damp mud, worn boot prints, restrained documentary light.

## Forbidden Drift

No sentimental portrait, no readable text, no clean symbolic footprints, no bright inspirational road.

## Acceptance Checklist

- Footprints are old and physical, not graphic symbols.
- Traveler continues away without turning.
- Mud and road remain real.
- Image status remains validation pending for parent/user confirmation.

## Prompt Handoff

Build the final prompt through the `gpt-image-2` Advisor / host-native workflow using A style and walking back character reference.
