SuperBizAgent-java/openspec/changes/archive/2026-07-05-mvp-demo-interview-runbook/proposal.md

Why

The MVP already has trace, evidence hardening, and evaluation artifacts, but the interview demo path is still too scattered. This change packages the existing capabilities into a repeatable demo runbook that can be executed and explained in a short interview window.

What Changes

• Add a focused interview walkthrough for the payment-timeout MVP demo.
• Add reusable request payloads and PowerShell scripts under mvp/demo.
• Add a trace inspection checklist that maps runtime output to the engineering story.
• Keep the change documentation-only and script-only; no backend runtime behavior changes.

Capabilities

New Capabilities

• None.

Modified Capabilities

• mvp-demo-trace-acceptance: Extend the demo acceptance surface with a repeatable interview runbook and executable local demo scripts.

Impact

• Affects mvp/demo documentation and scripts.
• Adds issue and devflow tracking files.
• No Java production code, API contract, database schema, or dependency changes are expected.
