Codebase Documentation and Developer Onboarding

This productized sample uses the public Directus repository at a pinned commit to demonstrate a reference-grade onboarding system for a large monorepo.

The documentation maps deployable surfaces, shared packages, architecture, setup, extension points, storage adapters, trust boundaries, contribution rules, glossary, diagrams, and a tested first-change path. Every repository-specific figure is tied to the inspected source rather than invented from a generic template.

The result is designed for teams inheriting an unfamiliar codebase, onboarding new developers, preparing a vendor handoff, or reducing knowledge concentration around one technical owner.
