## MODIFIED Requirements

### Requirement: MVP demo SHALL be reproducible for interviews
The MVP demo SHALL provide a repeatable way to show a diagnosis answer, trace, verifier evaluation, and feedback.

#### Scenario: interview demo check script records an evidence bundle
- **WHEN** the user runs the interview demo check script against a running `mvp-demo` service
- **THEN** the script SHALL submit a fixed Chat diagnosis request
- **AND** it SHALL fetch the trace for the same session id
- **AND** it SHALL submit useful feedback for that session
- **AND** it SHALL write chat, trace, feedback, and summary outputs under `mvp/demo/output/`

#### Scenario: interview demo check fails with actionable readiness output
- **WHEN** the target service is not reachable
- **THEN** the script SHALL fail before issuing diagnosis requests
- **AND** the failure message SHALL name the base URL and the expected startup profile

#### Scenario: interview documentation explains audit fields
- **WHEN** an interviewer asks how prompt or Gatekeeper changes are audited
- **THEN** the demo documentation SHALL point to `prompt_audit.version` and `gatekeeper_result.rule_set_version`
- **AND** it SHALL explain that deterministic eval fixtures are the regression source of truth
