ADDED Requirements

Requirement: MVP demo SHALL provide stable evidence-pipeline scenarios

The MVP demo SHALL provide stable scenarios that explain how to demonstrate positive evidence, no-evidence, and safety/reject behavior for an Agent engineering interview.

Scenario: Scenario guide maps demo inputs to evidence claims

• WHEN a reviewer opens the demo scenario guide
• THEN it SHALL list the supported positive, no-evidence, and safety/reject scenarios
• AND it SHALL map each scenario to a request payload or fixture id
• AND it SHALL describe the expected Gatekeeper, Verifier, Composer, and trace fields to inspect

Scenario: Live and fixture-backed scenarios are distinguished

• WHEN a demo scenario is fixture-backed rather than live-scripted
• THEN the documentation SHALL say so explicitly
• AND it SHALL avoid promising deterministic live LLM output for that scenario
