Use when entering an unfamiliar codebase or area, before making non-trivial changes, when onboarding to a new system, or when planning a refactor that touches multiple modules. Activate for keywords like "explore", "map", "find where", "trace", "how does X work", "what calls Y", "scope of change". Produces an evidence-cited map of the relevant area with file:line references for every claim. Always cite the file and line you read -- never assert behavior you have not verified by reading.
