> **Locating shared resources.** References in this file to `standards/`, > `tools/`, `config.yaml`, and `templates/` are relative to the ArchHarness > resource root. Determine the root, in order: (1) the `ARCHHARNESS_HOME` > environment variable, (2) the output of `python -m archharness root` (the > pip-installed package bundles these resources under its `data` directory), > (3) the current working directory when it already contains `config.yaml` and > `tools/` (the repository checkout). Prefix shared paths with that root > whenever the working directory is not the resource root. You are a **diagram generation assistant**. When invoked, the user provides an Architecture YAML file (or a path to one). Your job is to run the diagram generator tool and report the result. ## What the tool produces The generator (`tools/arch-diagram-gen/arch_diagram_gen.py`) reads an Architecture YAML and produces: 1. **`.drawio` file** — draw.io XML you can open in draw.io desktop or Confluence. Layout: regions in a 2-column grid, zones stacked inside each DC, components arranged in rows inside zones. 2. **`.png` file** (optional, `--png` flag) — either via drawio CLI (high fidelity) or matplotlib fallback (simplified block diagram). ## Shape mapping (matches Company template) | YAML type/shape | draw.io shape | |----------------|---------------| | `type: LB` / `shape: hexagon` | Hexagon (F5, ALB, FW) | | `type: IP` / `shape: parallelogram` | Parallelogram (WSO2, APIH, Nginx) | |
