Source analysis

Agent Evidence is motivated by repeated pressure in real agent products:

• Answers cite sources, but teams cannot tell which claim each source supports.
• Tool results affect decisions, but later reviews see only final prose.
• Runtime traces exist, but trace backends do not explain claim support, contradiction, omission, or review state.
• Generated artifacts need review, diff, version, export, and source evidence.
• Private data must be redacted without erasing the shape of the audit record.
• Long-running and remote agent tasks need evidence that survives disconnects and system boundaries.
• Support teams need portable exports that contain facts, hashes, schemas, and redaction state.
• Evals and audits need to distinguish unsupported claims from uncollected evidence.

The standard therefore focuses on portable evidence graphs rather than another logging, tracing, or citation format.
