Borrowed jurisdiction is the reframe that lets a leader keep secrets without owning the information door. A leader does not own secrecy; they are temporarily entrusted with it because another responsibility genuinely requires it. So confidentiality is purpose-bound, consequence-bound, audience-bound, and usually time-bound — legitimate while it protects the function (a negotiation that public disclosure would destroy) and illegitimate once it merely protects the holder (I’d prefer nobody know what concessions I made).
When it drifts
That shift is ontological drift inside a jurisdiction: the original form (confidentiality enables the work) quietly becomes a drifted one (confidentiality protects my standing). A simple counterfactual test exposes it — if revealing this did not threaten the holder personally, would the functional reason for secrecy still exist? If yes, the claim may hold; if the real harm is only embarrassment or lost support, the borrowed authority has been converted into private property it was never meant to be.
