The tool enables reviewers to trace conclusions back to supporting evidence across RAG pipelines and tabular transformations, with integrity guarantees costing tens of microseconds per event. In 2,000 randomized trials, verification flagged every injected mutation across four mutation classes.", "body_md": "arXiv:2607.09682v1 Announce Type: new\nAbstract: AI systems are increasingly used to assist consequential decisions in regulated domains such as auditing, finance, and healthcare. This creates a recurring obligation: an organization must be able to reconstruct, after the fact, which evidence informed a given conclusion, and to show that the record of that reasoning was not altered. Existing tools address related but distinct problems - model observability, drift monitoring, governance reporting - and are built for the machine-learning engineer operating a system, not the reviewer who must trace one specific conclusion back to its supporting evidence. We present AuditWeave, a lightweight Python library, with no runtime dependencies, that records the steps of AI-assisted and data-transformation workflows into a single append-only, hash-chained ledger. A small, system-agnostic event vocabulary spans both retrieval-augmented generation (RAG) pipelines and tabular/lakehouse transformations, so a conclusion that draws on both can be traced end-to-end through one record. Within a sealed ledger, any modification, reordering, insertion, or deletion of events is detectable through chain verification. We describe the design and evaluate recording overhead, scalability, and tamper-detection correctness on the reference implementation. The integrity guarantees cost tens of microseconds per event, and, as the hash-chain construction implies, verification flagged every injected mutation across four mutation classes over 2,000 randomized trials.", "url": "https://wpnews.pro/news/auditweave-a-tamper-evident-auditor-navigable-evidence-layer-for-ai-assisted-and", "canonical_source": "https://arxiv.org/abs/2607.09682", "published_at": "2026-07-14 04:00:00+00:00", "updated_at": "2026-07-14 04:21:57.680616+00:00", "lang": "en", "topics": ["ai-tools", "ai-safety", "ai-ethics", "developer-tools"], "entities": ["AuditWeave"], "alternates": {"html": "https://wpnews.pro/news/auditweave-a-tamper-evident-auditor-navigable-evidence-layer-for-ai-assisted-and", "markdown": "https://wpnews.pro/news/auditweave-a-tamper-evident-auditor-navigable-evidence-layer-for-ai-assisted-and.md", "text": "https://wpnews.pro/news/auditweave-a-tamper-evident-auditor-navigable-evidence-layer-for-ai-assisted-and.txt", "jsonld": "https://wpnews.pro/news/auditweave-a-tamper-evident-auditor-navigable-evidence-layer-for-ai-assisted-and.jsonld"}}
