Access to capability × Epistemic integrity

What scales is not truth but the price of being believed. When frontier verification sits in a few hands, "verifiable" quietly means "verified by them" — credential access becomes the bottleneck, not facts, and provenance becomes a toll road. Authenticated reality splits into a premium signed channel and a vast ambient tier assumed fake by default; the poor live in the ambient one. This is also the only corner where shared reality is cheaply maintained — concentration is precisely what makes provenance enforceable — but that maintenance must be governed into existence as plural, contestable public infrastructure, not assumed.

The equilibrium is neither chaos nor clarity but a permanent attention tax: authentication must win every time while forgery needs to win only once, so maintaining shared reality is a cost every participant pays continuously. The tools work; people stop using them. Verification fatigue, not deception, is the real failure mode — the corner drains silently toward fog whenever checking becomes one friction too many. The redemption is an interface problem: bake default-on provenance into capture devices, and you get shared reality with no custodian to capture.

The fog is not a side effect but a moat: the chokepoint actor navigates a world they have made unnavigable for everyone else, keeping a private clear channel while the public layer degrades. No censorship fingerprint needed — flood the zone until dissent is indistinguishable from synthetic noise. The population experiences not oppression but confusion, and confusion doesn't organise resistance. That is what makes this the most under-walked corner: stable, deniable, and invisible from inside. The thin redemption is structural — unlike the symmetric fog of the proliferated corner, the lever to de-fog exists and its location is known.

The failure isn't that lies win — it's that a shared public fact stops being economically viable. Institutions that need shared facts don't loudly collapse; they quietly delaminate into private, trust-gated enclaves. The public square isn't burned down; it's abandoned. One off-diagonal surprise: at full saturation forgery loses its power, because nobody trusted the unverified channel anyway — the danger is the transition, not the end-state. The deeper tax is coordination friction: every transaction that used to run on cheap public trust now needs its own ritual, making the economy slower and more local, permanently.
