Sardis v0.8.3: Demo Ops + Cloud Deployment (Cloud Run & AWS)

v0.8.3 focuses on one thing: making demos and staging environments reliable under real operating conditions. We added deployment automation for both Google Cloud Run and AWS App Runner, tightened live-mode operator UX in /demo, and documented the exact frontend-to-backend integration contract.

What Shipped

• Cloud Run deploy automation -- Staging script now handles artifact build/push, service deploy, env wiring, health checks, and post-deploy bootstrap guidance.
• AWS App Runner deploy automation -- ECR build/push and service create/update flow with runtime env injection.
• Frontend live-mode runbook -- Explicit mapping for SARDIS_API_URL, SARDIS_API_KEY, and DEMO_OPERATOR_PASSWORD.
• Demo reliability upgrades -- Clearer live lock messaging and persistent transaction history across refreshes.

Why This Matters for GTM

Design partners and investors do not test code in ideal conditions. They test links, flows, and operator handoffs. v0.8.3 reduces demo failure risk by making deployment and live-mode setup deterministic and repeatable.

• Faster path from local staging to shared demo URL
• Lower chance of live-mode lockouts during walkthroughs
• Clear fallback from live mode to simulated mode without breaking the narrative

Operator Checklist (Condensed)

1. Deploy API to Cloud Run (recommended) or App Runner
2. Bootstrap API key via auth bootstrap endpoint
3. Set landing env vars server-side only
4. Run blocked and approved scenarios in /demo live mode
