SynthLedger
Evidence layerAn audit trail layer that records AI decisions and human approvals — basis, approver, and stop conditions — and detects partial tampering via a hash chain. It answers “can we really let AI handle this?” with a record.
Illustrative example. No action is executed before approval.
Who, what, when, and on what basis.
Who
The approver and the acting principal are recorded, keeping human and AI decisions separate.
What
Each action — created, approved, executed — is recorded with its target and result.
When
A timestamp is kept for every action, so you can trace the sequence afterward.
Tamper-evident (hash chain)
Records are chained with prev_hash and sha256, so later rewrites can be detected.
Built into SynthAgent / standalone offering decided after the promotion gate
SynthLedger is the audit trail layer bundled with SynthAgent. It keeps evidence in a form you can use as a draft for external audit reports; full re-link resistance assumes an external anchor. A standalone offering is decided after the promotion gate. Planned for launch on AWS Marketplace in September 2026.
Answer with a record. Start with 30 minutes.
We will help design which evidence to keep for which operations, including the approval and logging design. Inquiries in English are welcome.
