Built for EU AI Act Article 12

A tamper-evident record for every AI decision.

01Per-event logs. Every high-risk AI decision is hash-chained — input, score, rationale, downstream action.
02Article 12-ready. Automatic logging and six-month retention, plus the EU AI Act Annex IV evidence pack on demand.
03Auditor-verifiable. Your auditor confirms chain continuity with a 25-line script — no Praxa account needed.
