repo-system-map

Analyze a software repository at the latest remote main commit and turn its implemented architecture into a citation-backed interactive isometric system map with a legend, selectable infrastructure buildings, dependency and payload flows, and plain-language learner explanations. For eligible public GitHub repositories, also contribute the verified map to tamdogood/CodeTerrain with a pull request. Use when a user provides a repository URL or asks to visualize, explore, learn, explain, or map a repo's architecture, infrastructure, runtime control flow, data flow, services, queues, stores, external systems, or deployment topology in an interactive UI.

# Repo System Map

Build an explorable model of what the repository actually implements. Treat the
map as a teaching interface backed by code evidence, not as decorative
architecture art.

## Contract

Accept:

- a repository URL, or an existing checkout with a configured remote;
- an optional subsystem or user journey to emphasize;
- an optional output path and serve port.
