A fiduciary-duty is a legally enforceable obligation requiring one party (the fiduciary) to act solely in the best interest of another party (the beneficiary). It is carved by three parameters: (1) the existence of a fiduciary relationship (formal, such as trustee-beneficiary, or de facto, such as attorney-client); (2) a conflict-of-interest space where the fiduciary's self-interest diverges from the beneficiary's interest; and (3) a vesting of discretionary authority in the fiduciary over the beneficiary's interests. Persistence mechanism: fiduciary-duties are codified in common law and statutory law, enforced through courts, and internalized in professional codes of conduct across law, medicine, finance, and governance.

fiduciary-duty requires the fiduciary relationship to exist now — without the relationship, the duty cannot operate. This is constitutive dependency per Law 8: remove the fiduciary relationship and the duty ceases to have meaning or force.

Fiduciary duty is a legal obligation defined and enforced by law. Remove law from the system and fiduciary duty ceases to exist as a binding construct. This is a present-tense constitutive dependency, not merely facilitative.
