Architecture Finding

Type: tech-debt
Affected area: tuna-os/docs repo root

The docs repository is the only one of 7 authorized repos without a justfile for build/test standardization. All other repos have at least one justfile defining standard workflows.

Impact

• Contributors must discover build/test commands from documentation
• No standardized entry point for CI operations
• Inconsistent with rest of the tuna-os ecosystem

Recommendation

Add a justfile with standard recipes: build, test, lint, serve for the Docusaurus site.
