short-drama-delivery-audit

Internal machine-owned gate used immediately before meta-short-drama publishes its final video. It does not call a model and never contacts a media provider.

The helper parses the canonical script.txt to identify active shots and their content durations. It then requires sanitized real-provider receipts for the reference image, every active shot image, and every active shot video; rejects placeholders, missing provider request/job IDs, and any runtime fallback substitution; and uses ffprobe to confirm that shot MP4s and the final MP4 are decodable and have the promised durations.

When Seedance rejects a shot under provider policy, its sidecar contains only the bounded reason provider_policy_rejected and an allowlisted policy code. The audit preserves those two fields, marks the shot not generated, and reports VIDEO_POLICY_REJECTED; raw provider text, signed URLs, request IDs, and secrets are discarded before this boundary.

The parent scheduler supplies one bounded disposition per paid step. The only accepted values are safe_no_submit, maybe_accepted, and receipt. It also supplies a separate bounded SHA-256 proof only when the exact bundled paid subprocess emitted a sanitized receipt on this invocation and the emitted JSON matched the resulting sidecar. A conclusive generated/policy receipt upgrades the public asset disposition to confirmed only when that current-run proof matches. The reserved runtime slots cannot be declared as plan steps.

When safe_no_submit accompanies a missing receipt and local fallback, the audit preserves the degraded provenance but does not claim that the provider may have billed the user. A maybe_accepted, receipt, missing, or malformed disposition without a conclusive, current-run-proven receipt remains fail-closed: the audit emits PAID_SUBMISSION_STATUS_UNKNOWN, a sanitized asset-name list, and a static instruction to check provider history before starting a replacement. Raw fallback output, child failure text, and provider text never cross into the verdict. A stale or forged workspace sidecar by itself is reported as RECEIPT_NOT_PROVEN_CURRENT_RUN and can never become confirmed.

Receipt or media evidence for a shot absent from the canonical script is reported as UNEXPECTED_PAID_ASSET and listed in unexpected_paid_assets. An incomplete receipt for that unexpected asset also carries the same fail-closed unknown-billing warning.

OVERVIEW.DURATION_S is story-content duration. The meta workflow adds a fixed two-second title and two-second ending, so the expected final duration is content duration plus four seconds. Small encoder timestamp differences are tolerated, but a three-second final file cannot satisfy a seven-second expected delivery.

Inputs

• with.run_dir: runtime-owned short-drama output directory.
• with.runtime.paid_submission_dispositions: bounded JSON object produced by the parent scheduler under its reserved output key. It contains only static step IDs and fixed disposition values.
• with.runtime.paid_submission_receipt_proofs: bounded JSON object produced by the parent scheduler under a second reserved output key. It contains only static step IDs and canonical sha256:<hex> receipt digests from exact bundled subprocess output captured during this run.
• with.runtime.fallback_outputs: mapping of shot number to the corresponding fallback step output. A non-empty value proves that local substitution ran.

Output

One JSON verdict with status (verified, degraded, or blocked), verified, media_provenance, active shots, content/final durations, whitelisted provider identifiers, per-asset paid_submission_dispositions, safe_no_submit_assets, may_have_been_billed, paid_submission_status_unknown_assets, unexpected_paid_assets, billing_guidance, and bounded issue codes. Raw prompts, provider responses, fallback output, signed URLs, and credentials are never emitted.
