Handrix internal docs

Documentation for engineers working on Handrix. Architecture, conventions, runbooks, and ADRs live here.

Four spaces, same Diátaxis split as the public docs:

• Tutorials — onboarding paths for new engineers.
• How-to guides — recipes for recurring engineering tasks.
• Reference — schemas, services, internal APIs.
• Explanation — architectural overviews and ADRs.

This site is auth-gated in production. Vendor names, costs, and unfinished work are fair game here.
