# S-03 Slide Brief V2

## Status

- Slide id: `s03`
- Version: `s03-v2`
- Running mode: `prompt and generate`
- Review: disabled
- Status: ready for prompt; generation blocked unless visible-context references can be loaded by the host session

## Source Basis

- `projects/2026-06-23-在路上/slides/slides.md`: `s03` is Prelude / 0:00-0:16, function "Old boot and backpack detail connects body to road", style anchor `character detail`, broad-run `s03-v1-image.png` exists as historical evidence only.
- `projects/2026-06-23-在路上/intake/阶段五-镜头清单骨架.md`: S-03 is "行囊与路的关系"; low-position local shot, old boot steps over the wet mud edge, backpack lower edge sways slightly, not a shoe advertisement.
- `projects/2026-06-23-在路上/visual-system/visual-system.md`: old boots and old backpack are identity motifs; the body connects to mud, road, and continuation.
- `projects/2026-06-23-在路上/visual-system/style/style-prompt-master.md`: use global documentary road-film kernel and the `Character detail with road texture` mapping, controlled mainly by Module A.
- `projects/2026-06-23-在路上/visual-system/characters/character-reference-registry.md`: object/body detail should use the master anchor or relevant crop/slice when coat, backpack, boots, or posture identity matters.

## Slide Function

Turn the traveler's body and props into evidence of the road. S-03 should not introduce face or hero identity; it should make the old boot, wet mud, backpack lower edge, and walking body detail feel inseparable from the road.

## First Read

Wet mud, boot contact, and road texture first; backpack / coat movement second. The viewer should feel bodily cost and continuation before reading the image as a person shot.

## Risk Class

- `object/body detail`
- Prop continuity: old boot, backpack, long dark coat
- Low-angle road texture

## Reference Plan

- Style module: A / Landscape-Led Road, adapted for close body / prop detail.
- Active style reference:
  - `projects/2026-06-23-在路上/intake/imgs/A.风景主导型蓝图.png`
- Style calibration reference:
  - `projects/2026-06-23-在路上/visual-system/style/style-anchor-board-v1.png`
- Character / prop references:
  - `projects/2026-06-23-在路上/visual-system/characters/character-anchor-v2-codex-posture-test.png` as `Image 1`, master identity / clothing / backpack / boots / posture reference.
  - `projects/2026-06-23-在路上/visual-system/characters/character-anchor-v2-walk-side-reference-crop-tight.png` as `Image 2`, side walking posture, coat motion, backpack placement, stride, and boot reference.
  - `projects/2026-06-23-在路上/visual-system/characters/character-slice-walk-side-v2-from-anchor.png` as `Image 3`, full-body walking-side silhouette and boot / coat / backpack continuity.

## Visual Requirements

- 16:9 photorealistic cinematic documentary road-film still.
- Low camera near wet mud, boot, road edge, and lower body.
- Old boot steps through or just past the wet muddy edge; mud compresses under the sole and small wet grit gathers around the boot.
- The lower edge of the old backpack or backpack strap is visible higher in frame, lightly swinging with the walking motion.
- Coat hem and dark road-worn trouser / boot relationship should be readable without showing face.
- The image must feel like body meeting road, not a product shot of footwear.

## Character Handling

Use real active references for prop and body continuity. No face is needed and no face should appear. Do not invent new stylish boots, a new backpack, or a fashion silhouette from text-only prompting.

## Composition / Scale

- Low-position local detail, 16:9 horizontal.
- Boot / mud interaction is the first-read anchor, but the boot should not be polished or centered like an advertisement.
- Use shallow foreground mud texture, road ruts, pebbles, puddle edge, and moving leg / coat / backpack fragments.
- Keep the body cropped naturally: lower leg, boot, coat hem, backpack lower edge or strap. No full portrait.

## Light / Color / Texture

Cold gray, earth brown, dark khaki, wet blue-gray, coal black, low saturation. Morning / pre-dawn damp cold. Mud must be tactile: wet grit, pressure, soft splash, rough stones, frost residue, road wear.

## Forbidden Drift

- No shoe advertisement, product hero lighting, clean boot close-up, fashion styling, luxury outdoor campaign, crisp studio product shot, readable brand logo, or polished gear catalog.
- No face, no front portrait, no heroic full-body pose, no looking back.
- No clean road, paved highway, vehicle, city UI, neon, cyberpunk, fantasy glow, motivational poster, broad sunrise, readable text, labels, logos, or watermark.
- Do not process S-02, S-04, or any other slide.

## Acceptance Checklist

- S-03 reads as "行囊与路的关系": old boot, wet mud, backpack / coat movement, continuing body.
- The first impression is bodily contact with road texture, not a shoe ad.
- Active character / prop references are selected and named.
- Module A road texture and global documentary road-film style are used.
- No review file is written.
- No S-02/S-04 or other slide is touched.

## Prompt Handoff

Use the `gpt-image-2` Skill Advisor / host-native workflow, with Module A adapted for body / prop detail and the selected active character references. The final prompt must state that `Image 1`, `Image 2`, and `Image 3` must be loaded into visible context before host generation. If this worker cannot load those references into the generation context, block before generation rather than producing a text-only prop / identity-critical image.
