PM Fungibility Principle
Canonical definition
Mimetic Premium (Status-PM) accumulated by an Individual-as-Object in one domain is deployable, without discount, in any other domain in which observers process that Individual as an Object of valuation. Fungibility is not a capacity of the PM-carrier but a property of the observer's receiving architecture: Common-Currency Integration tag-strips incoming Salience signals at the Decision Hub, destroying domain-of-origin information along with source-identity information (Source Opacity, Axiom 3), so Status-PM earned in one field is processed on the same neural footing as Status-PM earned in any other. Two corollaries follow. Domain Crossing: an Individual carrying high PM enters an unrelated domain already advantaged, because the receiving observers cannot register that the PM originated elsewhere. Domain-Boundary Conventionality: the boundaries that are supposed to confine Status to its domain of origin ("stick to your lane") are conventional counter-signals maintained against the architecture, not features of the receiving system, they are boundary-Beliefs, and they hold only while actively maintained.
Explanation
Fame is spendable anywhere. Status you build in one field (as an athlete, an actor, a business figure) carries over into completely unrelated fields, like politics, at full value. This isn't because the famous person is genuinely good at the new thing; it's because of how other people's brains work. When your brain registers that someone is high-status, it does not keep a note saying "high-status, but only at basketball." It just records "high-status," full stop, the label saying where the status came from was stripped off before you were ever aware of the signal. That is why the celebrity-turned-politician is the normal case rather than the strange one, and why "stay in your lane" is something people have to keep insisting on: the fence between fields is a shared Belief, not a fact of the wiring, and it only works for as long as everyone keeps believing in it.
Epistemic status
Framework-Specific Named Result. Derived consequence of Common-Currency Integration (Axiom 2) and Source Opacity (Axiom 3) applied to the domain-of-origin tag; canonical treatment in the Mimetic-Premium-as-social-currency analysis. Not an additional axiom.
