触控换媒｜接触触发、状态推进与成品回归

Create a new execution from the reusable mechanism, not a surface reskin of any reference video.

Workflow

1. Read references/summary.md for fit, input slots, and the concise starting example.
2. Read references/template.md completely before drafting.
3. Preserve the user's subject and objective, then fill every missing scene, trigger, event-chain, camera, sound, and payoff slot.
4. Treat these anchors as mandatory:

• Establish one bounded workspace, one primary object and one visible contact tool in reality.
• Toggle medium only at visible tool contact and preserve object registration across the boundary.
• Advance one irreversible build or preparation state after every toggle without resetting earlier progress.
• Return to photoreal reality with the completed object and original anchors visible.

5. Change source-specific people, setting, props, palette, dialogue, shot boundaries, sound family, and payoff surfaces together.
6. Compile MiniMax H3 and Seedance 2.0 independently; do not leak one model's field syntax into the other.
7. Silently verify anchor coverage, continuity, timing, physical causality, and anti-copy distance before returning the final prompts.

MiniMax H3

• Use the current official H3 task grammar and language profile.
• Separate integrated visual action, overall soundscape, and non-diegetic music or explicit silence.
• Use timestamps only to make event order executable; keep shots consecutive and duration-safe.

Seedance 2.0

• Define stable subjects once and preserve event order, camera motivation, sound intent, and overall duration.
• Use a simple paragraph for simple concepts or an ordered multi-shot structure for complex concepts.
• State overall duration once; do not copy H3 field labels or per-shot timecode grammar.

Output

Return one concept sentence, the filled slots, an anchor-coverage check, one MiniMax H3 prompt, one Seedance 2.0 prompt, and a short anti-copy validation note.

Non-Negotiable

• A subject-only request is underspecified. Preserve that subject and complete the mechanism instead of returning a generic portrait or showcase.
• Do not omit, reorder, or weaken a required anchor.
• Do not reuse source people, brands, dialogue, exact storyboard, signature props, exact timings, or recognizable effect surfaces.
