AI Invalid Verdict Schema

Initial Debt

Codex review found that the AI metadata schema required title and body even when the model returned valid: false.

Why It Matters

An invalid AI verdict could fail schema decoding before the rejection branch ran, causing finalizeReport to fall back to local metadata and accept a report the model rejected.

Resolution

apps/api/src/reports.ts now allows invalid verdicts to omit metadata and preserves explicit valid: false rejections.

Validation

• apps/api/src/reports.test.ts verifies { valid: false, reason } rejects without requiring generated title/body.
