Brief
Ship the flagship: Dockerized training + FastAPI serving + tracked runs + CI green, deployed to a free-tier cloud with a live URL.
Dataset
Churn-model data (m2 registry lineage) + warehouse-read evidence (m5-l15). Train/holdout hashes recorded; serving bytes must match.
Starter guardrails (plan 88)
m0 checklist repo shape; winner run from the registry; pinned image tag; secrets mounted, never baked; free-tier alarms on before deploy.
100-pt rubric
Live URL serves contract (health + predict + version) 25; cold-clone build 20; smoke green 15; tracking/registry lineage 15; monitoring sketch + alert 10; docs + cost appendix 15.
Deterministic checks -> LLM review
Checks: URL live (health 200 + version); image tag pinned; run lineage present; cost appendix non-empty. LLM review grades docs and trade-off notes.
