Detect spaghetti code and dependency cycles using graph theory, spectral analysis, and biomimetic patterns. Finds god functions, circular dependencies, dead code, suboptimal module boundaries, CI/CD pipeline deadlocks, and inefficient call patterns. Uses call graph topology (not just line-level metrics) to identify structural problems invisible to linters. Provides concrete fix patterns per domain. Use when the user says 'spaghetti', 'tangle', 'untangle', 'god function', 'god object', 'circular dependency', 'cycle detection', 'call graph', 'module coupling', 'dead code', 'code topology', 'complexity analysis', 'who calls who', 'démêler', 'couplage', 'dépendances circulair…
