Two-stage Policy Check Pipeline

Use different strictness levels at different pipeline points.

Stage 1: Script Light Check

• Model: gemini-3-flash-preview
• Input: source articles + generated script JSON
• Output: structured findings per rule

Stage 2: Asset Strong Check

• Model: gemini-3-pro-preview
• Input: articles + script + generated images
• Limit image payload to a fixed cap (24 images), add truncation finding if exceeded.

Normalization Rules

• Normalize finding status to PASS|WARN|REVIEW|BLOCK.
• Fill missing rules as PASS for full matrix coverage.
• If response is empty/unparseable, add model-response validity finding.

Persistence

Store for each run:

• stageStatus, overallStatus
• prompt artifact and response artifact in R2
• cost log entry
• findings table rows

Enforcement

• BLOCK prevents downstream generation/upload stages.
• Non-clean states can force private upload mode.
