https://mnstry.org/topics/boundary/ Five rooms on where a boundary actually is, as opposed to where the interface suggests it is. A view that hides and ships, a pipeline that finishes and sends, an architecture with no path to build a leak out of, an acceptance contract satisfied by an unusable screen, and a fact settled twice. The last two come from a single review and mark the honest limit of the argument the first three make. https://mnstry.org/writing/projection-is-not-protection/ https://mnstry.org/writing/projection-is-not-protection/ Why audience metadata, filtered views, and hidden panels protect nothing, and what five near-identical warnings in our own tooling reveal about how badly people want them to. The canonical treatment of the projection boundary.

The canonical treatment of the readiness-authorization split. Mon, 03 Aug 2026 00:00:00 GMT https://mnstry.org/writing/unleakable-context/ https://mnstry.org/writing/unleakable-context/ Why the only private context that stays private is the context with no path out of its domain, with Signal's subpoena record as the existence proof. The canonical treatment of the domain lock.

The canonical treatment of the on-screen geometry contract. Mon, 03 Aug 2026 00:00:00 GMT https://mnstry.org/writing/two-classifiers-two-truths/ https://mnstry.org/writing/two-classifiers-two-truths/ A keyboard that was open and closed at once inside one running application, and why the repair is a single owner per fact rather than two components instructed to agree more carefully. The canonical treatment of one authority per fact. Mon, 03 Aug 2026 00:00:00 GMT
