Compliance evidence is the documented, verifiable record that an organisation or process meets a regulatory, contractual, or standards-based requirement. It includes artefacts such as audit logs, sensor readings, certificates, attestations, and chain-of-custody records, ideally tamper-evident and timestamped. It matters because it converts asserted compliance into auditable proof, supporting attestations to regulators and customers and enabling automated verification in areas such as cold-chain integrity and supply-chain assurance.

- High-quality evidence is timestamped, attributable, and tamper-evident, increasingly anchored to immutable logs or distributed ledgers to resist after-the-fact alteration. In regulated supply chains, sensor telemetry such as temperature traces becomes evidence that goods stayed within tolerance, supporting audits and dispute resolution.
