Threat Model Generator

Generate a threat model for the following system using the STRIDE framework:

**System**: {{system}}
**Architecture**: {{architecture}}
**Data sensitivity**: {{dataSensitivity}} (public/internal/confidential/restricted)
**Trust boundaries**: {{trustBoundaries}}

For each STRIDE category (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege):

1. **Threat**: specific threat scenario (not generic)
2. **Attack vector**: how an attacker would exploit this
3. **Affected component**: which part of the system is vulnerable
4. **Impact**: what damage this causes (data, availability, reputation)
5. **Likelihood**: low/medium/high with reasoning
6. **Risk score**: impact x likelihood
7. **Mitigation**: specific countermeasure with implementation details
8. **Detection**: how to detect if this attack is occurring
9. **Residual risk**: what risk remains after mitigation

Prioritize by risk score. Include a data flow diagram description.
