# Forensic Evidence Graph Report: FEG-DEMO-001

- Subject: Example 1957 GT Berlinetta authenticity review
- Overall risk: 36.5/100
- Risk level: moderate

## Domain Risk

- Documentation: 66.4/100
- Identity: 49.4/100
- Inspection: 11.4/100
- Provenance: 16.6/100
- Technical: 29.1/100

## Rule Findings

- [high] Claim has no supporting evidence: Vehicle retains its factory color scheme
- [critical] Identity claim is contradicted: Vehicle retains its original chassis identity
- [medium] Timeline gap detected between 1962 and 1984.
- [medium] Timeline gap detected between 1984 and 2026.
- [medium] Evidence graph has 4 disconnected components.

## Central Nodes

- Vehicle retains its original chassis identity (`claim_identity_original`): degree 2
- Physical inspection record (`source_inspection`): degree 2
- Chassis stamping morphology matches expected pattern (`evidence_chassis_stamp`): degree 2
- Localized metalwork around stamping area requires escalation (`finding_reworked_stamp_area`): degree 2
- Vehicle retains its factory color scheme (`claim_factory_color`): degree 2

## Timeline Gaps

- 1962 to 1984
- 1984 to 2026
