understanding-codebase-cartography

Map unfamiliar codebases by identifying landmarks, boundaries, and flows to build a navigable mental model. Use when: (1) asked to explain code organization, architecture, or system structure, (2) multiple searches for individual files have been made without first examining directory structure, (3) changes or refactoring are proposed before analyzing what currently exists, (4) knowledge is limited to individual file contents rather than system-level organization.
