## Overview

Big Bang is a declarative delivery product for installing and maintaining hardened Kubernetes packages. The documented user workflow is to configure a deployment, apply its manifests to a cluster, and extend the baseline with optional packages. The chart tree identifies package implementations, while the README describes their capabilities. No source excerpts were supplied, so relationships are limited to those explicitly documented; the graph does not infer a reconciliation pipeline from the Flux-related files.

Main entry points: [`chart/Chart.yaml`](https://github.com/dod-platform-one/bigbang/blob/master/chart/Chart.yaml) (Deployment manifests), [`chart/templates`](https://github.com/dod-platform-one/bigbang/tree/master/chart/templates) (Add-on packages)
