## Slide Function
|
|
|
|
`S-04` is the early Section A road shot: cold morning frost and a long road. Its job is to extend the opening world-before-person grammar after `S-01`, keeping the road and cold terrain as the subject.
|
|
|
|
## First Read
|
|
|
|
The viewer should first read:
|
|
|
|
1. cold road and frosted mud;
|
|
2. long worn road receding through a large empty wilderness;
|
|
3. weak pre-dawn / morning haze;
|
|
4. only then, optionally, a tiny traveler far away as a non-identity-critical coordinate.
|
|
|
|
## Risk Class
|
|
|
|
- Risk class: `environment-only / distant human optional`
|
|
- Identity critical: no
|
|
- Face requirement: none
|
|
- Character references: not required unless a visible traveler becomes larger than a tiny distant coordinate.
|
|
|
|
## 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`
|
|
- Common calibration reference: `projects/2026-06-23-在路上/visual-system/style/style-anchor-board-v1.png`
|
|
- Character reference: none required for this prompt; if a traveler appears, keep the figure tiny, back/side, and non-face.
|
|
- Prior sequence context: `S-01` accepted opening road grammar, but do not copy its image directly.
|
|
|
|
## Visual Requirements
|
|
|
|
- 16:9 horizontal cinematic documentary still.
|
|
- Landscape-led road-film composition.
|
|
- Frost, wet mud, ruts, stones, puddles, sparse terrain.
|
|
- Low saturation: cold gray, earth brown, dark khaki, wet blue-gray.
|
|
- The road must be longer than the person and should dominate the frame.
|
|
- Any traveler must be tiny and secondary, not a portrait or hero backshot.
|
|
|
|
## Character Handling
|
|
|
|
No visible identity handling is required. If the image model introduces a distant traveler, the figure should be about `1/20` to `1/12` of the frame, seen from back or side, without readable face detail. Do not attach active character image references for this landscape-led no-face shot unless the parent session deliberately changes the shot to a visible traveler shot.
|
|
|
|
## Composition / Scale
|
|
|
|
- Camera: wide road-film frame, slightly low or eye-level observational viewpoint.
|
|
- Foreground: frosted mud, rough ruts, wet stones, dull puddle edges.
|
|
- Midground: long road bending or tapering into cold haze.
|
|
- Background: empty sparse wilderness, low horizon, weak morning haze.
|
|
- Person scale: absent preferred; tiny optional only.
|
|
|
|
## Light / Color / Texture
|
|
|
|
- Light: cold early morning / pre-dawn silver-gray, overcast or thin haze.
|
|
- Texture: documentary realism, real mud and frost, no polished scenic gloss.
|
|
- Warmth: almost none; if present, only a weak pale edge in the sky, not sunrise.
|
|
|
|
## Forbidden Drift
|
|
|
|
- No travel advertising.
|
|
- No postcard sunrise.
|
|
- No clean inspirational road.
|
|
- No centered heroic traveler.
|
|
- No portrait MV.
|
|
- No vehicle, animal, tent, camp, city, UI, logo, readable text, watermark, fantasy glow, or high-saturation scenery.
|
|
|
|
## Acceptance Checklist
|
|
|
|
- First read is cold road / frost / mud, not person.
|
|
- The road feels long and unresolved.
|
|
- Landscape and road dominate the frame.
|
|
- Any traveler is tiny, non-face, and non-identity-critical.
|
|
- Style follows active Module A and global documentary road-film kernel.
|
|
- Review file remains absent because review mode is disabled.
|
|
|
|
## Prompt Handoff
|
|
|
|
Build `s04-v2-prompt.md` through `gpt-image-2` Advisor / host-native workflow using Module A. Record the mode check, template/reference files read, active style references, and source files actually read. Do not require character image attachment. If host image generation cannot be accessed or the generated image cannot be saved to `s04-v2-image.png`, return blocked with the exact missing condition.
