# S-13 Slide Brief V2
## Status
- Status: ready for one-shot slide worker.
- Visible child session owns this brief.
- Worker must not modify this file.
- Review mode: none.
- Overwrite allowed: no.
## Source Basis
- `slides/slides.md`: `S-13`, Section B, calloused hand near backpack strap or cold rail.
- `visual-system/style/style-prompt-master.md`: character detail with B city-edge setting.
- `visual-system/characters/character-reference-registry.md`: active master, side/front identity, and relevant body/coat/backpack references.
- Sequence: after city pressure and corrosion, the body shows the cost through hand, strap, and cold rail.
## Slide Function
This is a character-detail slide. It should show bodily cost without becoming a glamour close-up: rough middle-aged hand, strap tension, cold rail or wall, dark coat, old backpack. The first read is touch and weight.
## First Read
Calloused hand, backpack strap or cold steel rail, dark coat sleeve, wet city-edge coldness.
## Risk Class
- `object/body detail`
- identity-relevant body / prop continuity
## Reference Plan
- Style module: `B | 高位观察:系统边缘里的小人物`, adapted to body detail.
- Active style reference: `projects/2026-06-23-在路上/intake/imgs/B.高位观察型蓝图.png`
- Character references:
- `projects/2026-06-23-在路上/visual-system/characters/character-anchor-v2-codex-posture-test.png`
- `projects/2026-06-23-在路上/visual-system/characters/character-anchor-v2-side-reference-crop-tight.png`
- `projects/2026-06-23-在路上/visual-system/characters/character-slice-side-v2-from-anchor.png`
- Role: clothing, backpack strap, body scale, side identity support, and hand/prop continuity.
## Visual Requirements
- 16:9 horizontal cinematic documentary still.
- Medium-close detail, not portrait.
- Hand is rough, middle-aged, practical; no clean advertising hand.
- Backpack strap or cold rail must carry weight/tension.
- City-edge background remains cold and utilitarian.
## Character Handling
This is identity/body-continuity relevant. The worker must load actual active character references before generation. If references cannot be loaded, block before generation.
## Composition / Scale
Hand/strap/rail in foreground or midground. Partial coat sleeve and backpack edge visible. Face absent or only a blurred edge; no direct portrait.
## Light / Color / Texture
Cold gray urban side light, wet metal, dark coat fabric, old strap texture, skin roughness, rust or concrete in background. Low saturation; avoid beauty lighting.
## Forbidden Drift
No fashion accessory ad, no clean product strap, no heroic clenched fist, no dramatic movie-poster hand, no luxury leather styling, no homeless collapse coding.
## Acceptance Checklist
- Hand/strap/rail read as bodily cost and persistence.
- Coat/backpack details match active character references.
- City-edge B pressure remains present.
- No face-centered portrait.
- No review file is produced.
## Prompt Handoff
Write `s13-v2-prompt.md` through the `gpt-image-2` Advisor / host-native workflow. Record mode, template/reference basis, sources read, and visible-context image roles. Generate `s13-v2-image.png` only after active character references are visible to the worker context.
