C.26:4.1 - Inherited QL boundary

Invariant QL-NQ: within FPF, quantum-like is a detached mathematical and representational modeling lens. It may use quantum-theory-derived structures such as contextual probability, Hilbert-like state spaces, non-Boolean logic, instruments, operator-like update, order effects, open-system descriptions, or incompatible probes.

Quantum-like does not assert physical quantum substrate, microscopic quantum process, qubits, quantum computation, physical entanglement, nonlocal causality, literal collapse, mystical observer effects, social substance, or collective mind. A physical-quantum claim is a different claim and needs separate physical or empirical support outside this pattern cluster.

Child patterns inherit QL-NQ. They should not restate the global boundary as local guidance unless they are repairing a specific confused phrase.
