BriefTrace — Evidence, Provenance & Re-Run Control Plane for Autonomous Research Agents

The Problem

AI research is no longer just “answer a question.” It is becoming a multi-step workflow that searches the open web, mixes in PDFs and files, consults proprietary data, generates charts, and returns long-form analysis.

That creates a new operational problem:

• teams need to verify not just the final answer, but the evidence trail;
• the same prompt can produce materially different outputs across runs;
• human reviewers still need to approve sensitive claims, but current tools expose little structured review workflow;
• organizations lack a durable memory of which sources, judgments, and overrides made a report trustworthy.

The opportunity is not “another AI research agent.” It is the control plane that makes agent output usable inside real professional workflows.
