WAN 3.0参考预算契约

Use this skill before an authorized WAN 3.0 video request. It checks a redacted request against the published duration, resolution, aspect-ratio, reference-count, and reference-duration constraints so a paid call is not started with an impossible media plan.

Prerequisites

• - Python 3.9 or newer.
• A UTF-8 JSON request with duration_seconds, resolution, ratio, and references.
• The buyer\'s own media inventory and current account/model access. This skill validates labels and numbers only.

Inputs and outputs

Run python scripts/check_request.py examples/pass_request.json --out contract.json --report contract.md.

The checker accepts 2-30 second requests, 480p/720p/1080p resolution labels, a declared ratio, up to 10 image references, 5 video references, and 5 audio references. It checks that each video or audio reference is between 2 and 15 seconds and that each modality\'s total is at most 15 seconds. It emits JSON and Markdown reports with api_call_authorized: false.

Execution and acceptance

1. 1. Replace redacted IDs and factual durations only.
2. Run the checker. Exit code 0 means the request is structurally within the documented budget; exit code 1 means hold it.
3. Confirm the current WAN 3.0 endpoint, account access, billing, reference URL/file rules, and content policy manually before upload or payment.

This is not a model-quality guarantee. It cannot prove a media file exists, is reachable, is authorized, or will preserve a character or style.

Privacy and recovery

Do not put tokens, private URLs, names, or media bytes in examples. If a reference is missing, over budget, or rights are unclear, correct the request rather than retrying a paid call.

Standalone use

The contract can be used on its own for an API handoff, batch queue, or operator checklist; the result auditor is optional.
