Add a top-level README plus production configuration, API, and rollout documentation. Also align deployment and runbook docs with the current runtime semantics, ports, and daily pipeline entrypoints.
Tighten real-ingestion success rules, separate scheduled reports from historical rebuilds, and persist source-level runtime audit across daily pipeline runs.
Also add the Phase 5 CI workflow contract plus verification updates and supporting docs so the full uncommitted change set can be validated together.
