Article 12 of Regulation (EU) 2024/1689 breaks into seven enforceable sub-requirements. ProofLink satisfies each one by architecture — not by policy promise. Here is the clause-by-clause map.
Article 12 requires high-risk AI systems to automatically record events over their lifetime, keep those records tamper-evident, and make them usable for traceability and post-market monitoring. ProofLink was built to this shape before the deadline existed: automatic logging, hash-chain tamper detection, human-readable audit trails, and Bitcoin-anchored proof of time.
Each Article 12 sub-requirement, matched to the ProofLink mechanism that satisfies it. All seven: native, in production.
1 · Automatic event recording throughout system lifetime
Every autonomous action triggers a receipt at execution time — no manual logging, no batching.
2 · Tamper-evident log integrity
SHA-256 hash chain: altering any receipt breaks the chain, producing immediate cryptographic evidence of tampering.
3 · Sufficient to identify risk circumstances
Receipts capture the trigger event, AI reasoning path, policy gate used, executor identity, outcome, and risk category label.
4 · Post-market monitoring support
The full ledger is queryable at verify.itechsmart.dev — filter by date, actor, category, severity. Export API available.
5 · Traceability of autonomous decisions
Every receipt links to the originating incident, the agent that acted, the approval chain, and the policy governing execution.
6 · Independent third-party verifiability
Bitcoin-anchored via OpenTimestamps — verifiable by any party using open-source tooling, without iTechSmart involvement.
7 · Defined retention period
Receipts are permanent on-chain, with configurable local retention windows for jurisdiction-specific compliance periods.
