Limitations

TrustChain TRL7 pilot — audit-ready evidence, not production certification.
Custody and risk events are DB audited in E11/E12; not all events are on-chain.
Document bytes remain in private off-chain object storage; only hashes and proofs are verified here.
PDF export is HTML print-ready in E13; native PDF generation is planned for a later phase.
