feat(c4-diagrams): add multi-boundary layout patterns#6
Conversation
Add documentation for creating clean, readable C4 diagrams with multiple system boundaries (e.g., cross-control-plane architectures). New patterns documented: - Side-by-side boundary placement using Rel_L/Rel_R - Grid structure within boundaries (2x2 layout) - Relationship direction guidelines for different scenarios - Data flow alignment (left-to-right: entry → processing → execution) - Complete cross-control-plane example These patterns emerged from designing the Functions service control plane architecture diagram and help avoid overlapping lines and cluttered layouts.

Add documentation for when to use Container vs Container_Ext (and other _Ext variants) based on ownership: - Internal: elements your team owns and maintains - External: elements owned by other teams or external services Key pattern: "Resource you create, other service processes" should be Container_Ext since the other team owns the controller that processes it. Includes: - Ownership rule explanation - Common patterns table with rationale - Functions service example - Context vs Container diagram guidance Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
