# S-20 Slide Brief V3

## Status

- Status: child-owned brief ready before worker launch.
- Slide/version: `S-20 / s20-v3`.
- Worker profile: `video-slide-production`.
- Running mode: `prompt and generate`.
- Review: none / intentionally suppressed.
- Overwrite allowed: no.

## Source Basis

- Shot skeleton: `那一簇火 / 微弱支撑`.
- Source image context: `s19-v2-image.png` accepted; `s20-v1-image.png` broad-run historical only; `s20-v2` incomplete session-10 evidence only.
- Style authority: `visual-system/style/style-prompt-master.md`, module D with mud/stone detail.

## Slide Function

Bring the small fire slightly closer than S-19 so it lights only a small patch of mud and stones. The fire has temperature, but it must not become lively, cozy, victorious, or camp-like.

## First Read

Small local firelight on mud and stones before the traveler.

## Risk Class

- `distant human`
- `fire / road transition`

## Reference Plan

- Style module: D / Night Road Fire.
- Active style references:
  - `visual-system/style/style-anchor-board-v1.png` as common calibration.
  - `intake/imgs/D.夜路篝火型蓝图.png` as D fire/road style reference.
  - `slides/s19/s19-v2-image.png` as accepted sequence continuity reference only; do not regenerate S-19.
- Character references:
  - `visual-system/characters/character-slice-walk-back-v2-from-anchor.png` as distant/back traveler silhouette reference.
  - Identity detail must not drive the shot; traveler remains at the frame edge.

## Visual Requirements

- Horizontal 16:9 cinematic documentary still.
- Night or deep pre-dawn road edge.
- Small fire closer than S-19, but still restrained.
- Warm orange light only on a small patch of wet mud, stones, and road texture.
- Traveler at the frame edge, small/medium-small, not centered.

## Character Handling

Use the loaded walking-back slice for silhouette and outfit continuity only. No face, no portrait identity, no centered hero stance.

## Composition / Scale

- Environment first, local fire/mud second, traveler third.
- Fire: about 4-7% of frame.
- Traveler: frame edge, about 1/8-1/6 if visible.
- Road must continue beyond the fire.

## Light / Color / Texture

Low saturation, coal black, wet blue-gray, earth brown, mud texture, small local warm orange.

## Forbidden Drift

No bonfire, no tent, no camping chairs, no cookware, no group, no reunion, no victory, no cozy campsite, no large theatrical flames, no warm sunset.

## Acceptance Checklist

- New append-only version `s20-v3`.
- Prompt/image/return only by worker.
- No review file.
- MiniMax/MCP/external vision not used.
- Actual style and silhouette references loaded into worker context before generation.

## Prompt Handoff

Write `s20-v3-prompt.md`, generate `s20-v3-image.png`, and write `session-11/returns/s20-v3-slide-agent-return.md`. Record Skill mode, template/reference paths, loaded image roles, source files read, host output path if available, and SHA256 if the project image exists.
