# 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`
