# Architecture Diagramming Standard

## **Priority: P1 (Standard)**

## Guidelines

- **Use C4 Model**: Context->Container->Component->Code.
- **Audience-Centric**: Tailor abstraction (Execs vs. Devs).
- **Select Type**: Sequence (Protocol), ERD (Data), State (Lifecycle), Cloud (Infra). _See [Selection](references/diagram-selection.md)_
- **Explicit Labels**: Label _every_ arrow (e.g., "Uses", "HTTPS").
- **Consistent Notation**: Cylinders=DB, Rectangles=Systems, Dashed=Async.
- **Metadata**: Title, Date, Version, Author.
- **Legend Mandatory**: Define all shapes/colors/styles.
- **Direction**: `graph LR` (Flow) or `graph TD` (Hierarchy).
- **Deployment**: Map containers to infrastructure.
- **Governance**: CRITICAL: Review [best-practices.md](references/best-practices.md) before starting.

## Anti-Patterns

- **Mixed Levels**: DB columns in System Context.
- **Unlabeled Arrows**: Ambiguous relations.
- **Mystery Shapes**: Undefined in Legend.
- **Dead Ends**: Unconnected nodes.
- **Clutter**: >20 nodes/diagram.
- **Acronyms**: Undefined abbreviations.
