MCP-first code navigation for this codebase. Use before any symbol lookup, file search, dependency trace, impact analysis, or codebase evaluation — replaces grep/glob/read with O(1) fmm_* tool calls. Trigger when: starting any task involving unfamiliar code, navigating code structure, finding where a symbol is defined, checking what imports a file, tracing blast radius before a rename, mapping test coverage, or evaluating/auditing a codebase.
