  "mechanism": "A PolymorphicSolver is any entity — from a fleeting thought process to a complex swarm — that implements the five-surface contract {{solver}} specifies (Manifest via {{card}}, Execute, Consult, Verify via {{validate}}, Feedback — emits a typed {{performance_signal}}). Manifest and Execute are mandatory; Consult/Verify/Feedback are optional but strongly recommended at hard seams. The pattern is named for its polymorphism: any substrate conforming to the contract qualifies — LLM, human, hybrid, tool-using agent, nested composition, or mechanical dispatcher — not just cognitive ones. It acts as a fractal node in the {{universal_solver_tree}}, accepting a {{task}} and using {{reason}} to orchestrate a lifecycle on a {{solver_node}}. It yields a {{solution}}, wrapping operations like {{tool_invoke}} with {{compute_budget}} checks, {{socratic_loop}} refinement, or {{reflexion}} for self-improvement. When operating as a dispatcher (routing sub-tasks to child solvers), it maintains a local {{pathway_memory}} so routing decisions compound as experience accumulates — the property that gives the fractal structure its learning dynamics.",
