AuditWeave: A Tamper-Evident, Auditor-Navigable Evidence Layer for AI-Assisted and Data-Transformation Workflows

Short summary

AuditWeave is a lightweight Python library that records AI-assisted and data-transformation workflow steps into an append-only, hash-chained ledger for post-hoc auditability. It uses a system-agnostic event vocabulary spanning RAG pipelines and tabular transformations, enabling end-to-end tracing of conclusions to supporting evidence. Integrity guarantees cost tens of microseconds per event, and verification detected all injected mutations across 2,000 randomized trials.

• •Lightweight Python library creates tamper-evident hash-chained ledger for AI workflow audit trails
• •Spans both RAG pipelines and tabular/lakehouse transformations with one event vocabulary
• •Tens of microseconds overhead per event; 100% mutation detection across 2,000 trials
