Build Week: One-command deterministic platform demo

[CodeBuildder]

Objective

Provide one deterministic, judge-safe command that launches or reuses Argus, Phoenix, Sentinel, and the Sentinel Operations Graph (SOG), seeds one truthful cross-agent lifecycle, verifies the resulting correlated incident, and prints every console URL.

Command

make demo-platform

Default safety

The default path uses replayed Argus evidence plus the Phoenix simulator. It must not create Chaos Mesh resources or disrupt Kubernetes workloads. Live k3s faults remain a separately authorized mode.

Scope

• preflight repository layout, local dependencies, Kubernetes context, and required services
• reuse already healthy services instead of failing on occupied ports
• start missing port-forwards and local APIs/UIs
• load OPENAI_API_KEY without printing it
• use reserved ports: Argus 5173, Phoenix 5174, Sentinel 5175
• publish one shared correlation ID with explicit replayed/simulator provenance
• verify exactly one correlated Sentinel case
• print judge URLs and evidence identity
• supervise only processes started by the command and clean them up on exit
• document dry-run and troubleshooting paths

Acceptance criteria

• One command reaches a ready demo from the documented three-repository checkout.
• Default execution cannot trigger live Chaos Mesh.
• Existing healthy services are reused safely.
• The seeded case appears in Sentinel with Argus + Phoenix evidence.
• Provenance remains replayed + simulator.
• Ctrl-C cleans up only command-owned processes.
• Shell syntax, existing tests, and UI builds pass.
