# S-12 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-12`, Section B, rust, dripping water, time wear.
- `visual-system/style/style-prompt-master.md`: Module B city-edge pressure.
- `visual-system/characters/character-reference-registry.md`: active walking/back references if a traveler trace appears.
- Prior sequence: `S-10` steel canyon and `S-11` cold wall / no home.

## Slide Function

This is a city-edge texture and time-wear slide. The point is not a portrait; it is the world corroding around the traveler. Rust, water, concrete seams, and wet decay should carry the emotional pressure.

## First Read

Rust streaks, dripping water, wet concrete, old steel, and time-worn city edge. The traveler may appear only as a small peripheral passing trace.

## Risk Class

- `environment-led`
- `distant human` if traveler is included

## Reference Plan

- Style module: `B | 高位观察：系统边缘里的小人物`
- Active style reference: `projects/2026-06-23-在路上/intake/imgs/B.高位观察型蓝图.png`
- Character references if traveler appears:
  - `projects/2026-06-23-在路上/visual-system/characters/character-anchor-v2-walk-back-reference-crop-tight.png`
  - `projects/2026-06-23-在路上/visual-system/characters/character-slice-walk-back-v2-from-anchor.png`
- Role: style/texture reference plus distant walking-away identity/body continuity.

## Visual Requirements

- 16:9 horizontal cinematic documentary still.
- Rust, dripping water, wet concrete, pipe or rail, old steel, gray wall, cold utilitarian city edge.
- Traveler is optional but recommended as a small edge trace, about `1/14` to `1/10` of the frame.
- The frame should feel like time has accumulated on surfaces.

## Character Handling

If the worker includes the traveler, load the actual character reference images. If the worker cannot load them, generate an environment-only shot rather than a text-only identity-critical traveler.

## Composition / Scale

Close-to-medium environmental texture with depth: rust and drip details in foreground or midground, city-edge structure behind, small passing traveler if included.

## Light / Color / Texture

Cold gray light, wet stains, rust brown, dirty water, concrete pores, steel scratches, low saturation. The wet surface should feel real, not decorative.

## Forbidden Drift

No cyberpunk neon, no clean industrial design poster, no polished architecture ad, no abstract texture wallpaper, no heroic person, no readable text/logos.

## Acceptance Checklist

- Rust and dripping water are the first read.
- Style B pressure remains clear.
- Traveler, if visible, is small and reference-guided.
- Image supports sequence continuity after S-10/S-11.
- No review file is produced.

## Prompt Handoff

Write `s12-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 `s12-v2-image.png` only when required references are visible or choose environment-only framing.
