S-03 Slide Brief V2

Status

• 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.
