# S-20 Slide Brief V2

## Status

- Status: ready for one-shot worker.
- Slide: S-20.
- Version: `s20-v2`.
- Review: none / intentionally suppressed.
- Overwrite allowed: no.

## Source Basis

- Source shot skeleton: `S-20: 那一簇火 / 微弱支撑`.
- Core direction: the small fire is closer than S-19 and lights only a small patch of mud and stones; traveler remains at the frame edge.

## Slide Function

Show the fire has temperature, but not liveliness. It supports the road emotionally without becoming a camp or rest scene.

## First Read

Small firelit mud/stones first, surrounding night road second, frame-edge traveler last.

## Risk Class

- `distant human`
- `core motif`

## Reference Plan

- Style module: D / Night Road Fire with mud/stone detail.
- Active style references:
  - `projects/2026-06-23-在路上/visual-system/style/style-anchor-board-v1.png` as common A/B/C/D calibration board.
  - `projects/2026-06-23-在路上/intake/imgs/D.夜路篝火型蓝图.png` as D firelight reference.
- Sequence continuity:
  - Use `S-19/s19-v2` only if it exists before this worker launches; otherwise rely on D style master.
- Historical contrast:
  - `projects/2026-06-23-在路上/slides/s20/s20-v1-image.png` is broad-run historical evidence only, not an accepted final.
- Character references: none by design. Traveler remains at edge and identity detail should not drive the shot.

## Visual Requirements

- 16:9 horizontal cinematic documentary road-film still.
- Fire closer than S-19 but still small and restrained.
- Warm orange light falls only on a small patch of wet mud, stones, and roadside grit.
- Traveler remains at frame edge or as a small silhouette, not seated or resting.

## Character Handling

Back/side silhouette only if visible. Do not use face or portrait identity.

## Composition / Scale

- Medium-wide to distant frame.
- Fire about `4%-7%` of frame.
- Traveler about `1/10-1/6` at the edge, secondary.
- Keep negative space and dark road around the fire.

## Light / Color / Texture

- Coal black and wet blue-gray night with local warm orange firelight.
- Mud, stones, and wet road texture must be tangible.
- Warmth is local, not a broad orange wash.

## Forbidden Drift

No campsite, tent, chairs, cookware, social gathering, cozy lifestyle, large bonfire, heroic pause, fire worship, fantasy glow, labels, logos, UI, readable text.

## Acceptance Checklist

- Fire illuminates a small mud/stone patch.
- Traveler remains peripheral.
- No camp props or group appear.
- D warmth is restrained.
- No review file is produced.

## Prompt Handoff

Worker must write `s20-v2-prompt.md`, generate/copy `s20-v2-image.png`, and write `session-10/returns/s20-v2-slide-agent-return.md`. Brief and packet are read-only.
