Free tier gives counts, not the timeline

Paid deliverables

Verification report (serial number + ed25519 signature + content hash, $2) — GET /v1/report/{cvin}. If a device has no real external observation, the report is issued free and clearly marked demo_report.

Record contents are stored in Chinese and rendered on the Chinese page, which is authoritative for record text. Machine-readable: GET /v1/resolve/{cvin}.
