+# System Overview
+
+## Product
+
+Reanimator Chart is a small Go web viewer for Reanimator hardware JSON snapshots.
+
+It is designed to be embedded as a module in other Go applications that already collect audit data and emit Reanimator-compatible JSON.
+
+## Active Scope
+
+- Render one Reanimator JSON snapshot as HTML
+- Read-only presentation of top-level metadata and hardware sections
+- Tabular rendering for arrays such as `cpus`, `memory`, `storage`, `pcie_devices`, `power_supplies`, and sensor subsections
+- Status color coding for fast scanning
+- Lightweight section navigation
+- Standalone HTML rendering or embeddable HTTP handler
+
+## Explicitly Out Of Scope
+
+- Parsing vendor logs or archives
+- Collecting hardware data
+- Converting non-Reanimator formats
+- Editing or mutating snapshot data
+- Derived health analytics not present in the input JSON
+- Timeline/history reconstruction
+- Database storage
+- Background jobs, upload pipelines, or batch processing UI
+
+## Product Rules
+
+- The viewer must display the input snapshot as-is.
+- The viewer may format values for presentation, but may not invent new data.
+- Unknown fields must still be visible in the UI.
+- Known sections may have a preferred visual order, but payload content remains authoritative.
+
+## Tech Direction
+
+- Go HTTP server / embeddable handler
+- Server-rendered HTML
+- Minimal client-side JavaScript only for presentation helpers such as expand/collapse and sticky section navigation
+- No SPA framework unless a concrete need appears later
+
+## Local Run
+
+Expected future command:
+
+- `go run ./cmd/reanimator-chart`
