Evidence

Evidence links claims to proof. Every assertion in an Echo traces back to sources, with clear provenance and confidence scoring.

Why evidence matters

When an AI agent says a venue has an "intimate atmosphere," that claim needs backing. Evidence provides the chain: where the data came from, how it was processed, and how confident the system is in the claim.

What evidence contains

Each piece of evidence connects a claim to its supporting data:

ComponentWhat it captures
ClaimThe assertion being supported
SourceWhere the data comes from
ProvenanceThe chain from original data to processed claim
ConfidenceHow strongly the evidence supports the claim

Confidence scoring

Confidence reflects how well-supported a claim is. Higher confidence comes from more data, stronger agreement between sources, fresher information, and more reliable source types.

A claim backed by many recent, agreeing sources scores higher than one with sparse or conflicting information.

What agents can do with evidence

When a guest asks "why this hotel?", an agent with access to evidence can give specifics rather than assertions. It can explain what sources support a claim and how confident the system is.

This is transparent reasoning rather than a black box.
